FAQ

## LTM46xx series — common questions

### What replaces the LTM46xx series?

HGCHIPS supplies 21 pin-compatible replacements covering the ADI LTM46xx μModule family. Every module is compared against the original datasheet — footprint, pin-out, input and output voltage range, output current and package.

### Do LTM46xx replacements need a board redesign?

No board redesign is intended. The modules share the original LGA / BGA land pattern, so the intent is a drop-in swap. Always qualify on your own board before volume use — we provide samples from 10 pcs and lot-level test reports.

### What is the minimum order quantity?

Samples start at 10 pcs, with sample cost credited against your first production order.

### Why do teams open a second source on the LTM46xx family?

The main driver is supply certainty: ADI allocation and premium broker pricing on long-lead parts, versus a long-term stock commitment on our side.

## Send your LTM46xx BOM line

We confirm compatibility, share test reports and quote within 24 business hours — samples from 10 pcs.
