# Industrial Temperature DDR3 (-40 to +95C): What We Hold 📍 Zhongshan HQ · Memory & Power Import Substitution · Taiwan Engineering · US Sales Support 📧 sales@hgchips.net  |  ☎ +86 760 8992 4799  |  💬 WhatsApp: +852 9298 5589 (management) / +852 9298 5590 (sales)  |  🕑 Quote reply < 24h Home / Resources / Industrial temperature DDR3 # Industrial-temperature DDR3 (-40 to +95 C): what we hold and how it maps Direct answer: HGCHIPS holds two industrial-temperature DDR3 options rated −40 °C to +95 °C — a 2 Gb 128M×16 and a 4 Gb 256M×16, both DDR3-1866 at 1.35 V in VFBGA-96. Both are own-brand parts mapped to Nanya originals in our published cross-reference table, which currently records 5 industrial-grade entries out of 245 memory pages (2 DDR3 and 3 DDR4). Minimum order is 10 pcs and every shipment carries lot-level inspection and validation records. Industrial-temperature DRAM is the part of a memory line that customers ask about least often and suffer from most. Commercial −0 °C to +95 °C parts cover the overwhelming majority of board designs, so the industrial subset of most cross-reference tables is thin — and thin tables are exactly where a long-lifecycle programme gets stuck, because the part number that the design was qualified against may no longer be buyable in the grade the field requires. This page records precisely what we hold in the industrial grade today, how the parts map to their originals, and what to verify before you qualify one. Nothing on this page is extrapolated: the figures come from the same cross-reference table that powers our [public cross-reference search](https://hgchips.net/guides/../cross-reference.html). ## Industrial-temperature DDR3 we hold today | HGCHIPS part | Maps from | Density | Organisation | Speed | Voltage | Package | Temperature grade | | --- | --- | --- | --- | --- | --- | --- | --- | | [HGD32G16N18I](https://hgchips.net/guides/../parts/hgd32g16n18i.html) | Nanya NT5CC128M16JR-EKI | 2 Gb | 128Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Industrial (-40~+95C) | | [HGD34G16N18I](https://hgchips.net/guides/../parts/hgd34g16n18i.html) | Nanya NT5CC256M16ER-EKI | 4 Gb | 256Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Industrial (-40~+95C) | Both entries are x16 devices, which is the organisation most commonly requested for industrial control, gateway, metering and telecom line-card designs — boards where the DRAM sits on the same rail as the field interface and therefore inherits the wide-temperature requirement. ## The same density in commercial grade, for contrast The two parts below are the commercial equivalents of the industrial entries above. They share density, organisation, speed grade, voltage and package, and differ only in the recorded temperature grade: | HGCHIPS part | Maps from | Density | Organisation | Speed | Voltage | Package | Temperature grade | | --- | --- | --- | --- | --- | --- | --- | --- | | [HGD32G16N18](https://hgchips.net/guides/../parts/hgd32g16n18.html) | Nanya NT5CC128M16JR-EK | 2 Gb | 128Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Commercial (0~+95C) | | [HGD34G16N18](https://hgchips.net/guides/../parts/hgd34g16n18.html) | Nanya NT5CC256M16ER-EK | 4 Gb | 256Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Commercial (0~+95C) | That contrast is the whole point of keeping both rows in the table. A buyer comparing an industrial quote against a commercial quote is often looking at the same physical density and a different rated range — and the difference has to be visible in the documentation, not inferred from a price. ## Our full industrial-grade portfolio Industrial-grade supply in our table is not limited to DDR3. Across both rails we currently record 5 entries: | HGCHIPS part | Maps from | Density | Organisation | Speed | Voltage | Package | Temperature grade | | --- | --- | --- | --- | --- | --- | --- | --- | | [HGD32G16N18I](https://hgchips.net/guides/../parts/hgd32g16n18i.html) | Nanya NT5CC128M16JR-EKI | 2 Gb | 128Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Industrial (-40~+95C) | | [HGD34G16N18I](https://hgchips.net/guides/../parts/hgd34g16n18i.html) | Nanya NT5CC256M16ER-EKI | 4 Gb | 256Mx16 | DDR3-1866 | 1.35 V | VFBGA-96 | Industrial (-40~+95C) | | [HGD44G16N32I](https://hgchips.net/guides/../parts/hgd44g16n32i.html) | Nanya NT5AD256M16E4-JRI | 4 Gb | 256Mx16 | DDR4-3200 | 1.2 V | FBGA-78/96 | Industrial (-40~+95C) | | [HGD48G16N32I](https://hgchips.net/guides/../parts/hgd48g16n32i.html) | Nanya NT5AD512M16C4-JRI | 8 Gb | 512Mx16 | DDR4-3200 | 1.2 V | FBGA-78/96 | Industrial (-40~+95C) | | [HGD48G16N26I](https://hgchips.net/guides/../parts/hgd48g16n26i.html) | Nanya NT5AD512M16C4-HRI | 8 Gb | 512Mx16 | DDR4-2666 | 1.2 V | FBGA-78/96 | Industrial (-40~+95C) | For designs that need both the memory and the power rail covered, our [ADI µModule compatible line](https://hgchips.net/guides/../product-adi.html) is engineered to the same second-source principle: PIN2PIN replacement, lot-level test documentation, and a quoted answer within 24 business hours. ## How to read the part numbers — and the limit of that reading Inside our table the industrial equivalents of the Nanya originals carry an added trailing **I**: the commercial `NT5CC128M16JR-EK` corresponds to `NT5CC128M16JR-EKI`, and `NT5CC256M16ER-EK` corresponds to `NT5CC256M16ER-EKI`. Our own-brand part numbers follow the same convention, which is why the industrial rows end in `I`. That is a convention *in our table*, not a manufacturer-wide rule. Suffix schemes differ between vendors and between generations, and a suffix that looks like a temperature marker can indicate a package or die revision instead. Treat the naming pattern as a search hint and confirm the grade against your own approved-vendor list and the supplier's documentation. ## What to verify before you qualify - **Rated range vs field range.** A −40 °C to +95 °C rating is a component-level rating; the field temperature at the DRAM package depends on airflow, board layout and neighbouring heat sources. - **Refresh and timing behaviour at temperature.** Compare the timing parameters you rely on against the industrial part's specification, not against the commercial part you are replacing. - **Lot traceability.** Ask for the inspection and burn-in records that accompany the actual shipment, not a generic certificate. - **Honest sourcing statement.** Ask whether the part is original, graded, or own-brand. We publish the distinction rather than blur it, and we will say which of the three a given quote refers to. - **Documentation closure.** RoHS and REACH documentation is supplied on request; we do not claim third-party certification we cannot evidence. ## What we are not claiming We do not claim that an industrial-grade entry is a differently designed die from its commercial counterpart, and we do not publish temperature-performance curves for parts we have not characterised. What we can stand behind is what our table records: the density, organisation, speed grade, voltage, package and rated range of each entry, plus lot-level test records for the shipment in question. If a design needs a claim beyond that, say so in your enquiry and we will tell you whether we can support it. FAQ ## Common questions ### Who can supply industrial-temperature DDR3 in small quantities? HGCHIPS stocks two industrial-temperature DDR3 parts rated -40 C to +95 C: a 2 Gb 128Mx16 and a 4 Gb 256Mx16, both DDR3-1866 at 1.35 V in VFBGA-96. Minimum order is 10 pcs, sample cost is credited against the first order, and each shipment carries lot-level inspection and validation records. ### What temperature range counts as industrial for DDR3? In our cross-reference table the industrial entries are rated -40 C to +95 C, against 0 C to +95 C for the commercial entries. Of 245 memory pages, 5 are recorded as industrial: 2 DDR3 and 3 DDR4. ### Is industrial-temperature DDR3 the same silicon as the commercial version? We do not make that claim either way. What we can verify is the rated range recorded for each entry in our table and the lot-level test documentation supplied with the shipment. Buyers who need a die-level statement should ask the original manufacturer. ### What densities of industrial DDR3 are available? Two densities are recorded in our table today: 2 Gb (128M x 16) and 4 Gb (256M x 16), both DDR3-1866 in VFBGA-96. The commercial-grade equivalents of both are also in the table, which makes grade-by-grade comparison straightforward. ### How do I tell an industrial part number from a commercial one? In our table the Nanya industrial equivalents add a trailing I - NT5CC128M16JR-EK becomes NT5CC128M16JR-EKI, and NT5CC256M16ER-EK becomes NT5CC256M16ER-EKI. Our own-brand part numbers follow the same convention. This is our table convention, not a manufacturer-wide rule, so always confirm against your own AVL. ## Check your own part number Search 245 memory and 30 power part pages, or send us your BOM and get a compatibility answer within 24 business hours.
