LMV321 — graded alternatives

TI

4 verified matches, sorted by compatibility grade and evidence strength. Differences are listed before any compatibility claim. Data source: live tenant catalog. Data verified: 2026-07-13T00:00:00.000Z

The closest documented alternative to LMV321 is SGMicro SGM321, graded FUNC (functional alternative that may need board or BOM changes, high confidence). No differences are recorded in the cited evidence; review both datasheets for application conditions. 3 further graded candidates listed below. Every match is an engineering-review candidate, not an unqualified drop-in claim.

Engineering questions about this cross-reference

What are the differences between SGM321 and LMV321?

No differences are recorded in the cited evidence for this pair. That is not a guarantee of identity — review both datasheets for electrical, timing and application conditions.

Is SGM321 a drop-in replacement for LMV321?

SGM321 is a FUNC-graded engineering-review candidate (functional alternative that may need board or BOM changes). Cited evidence must be reviewed against your application conditions. Production use requires validation on your board.

What is the difference between P2P, PIN and FUNC grades?

P2P is a documented drop-in candidate, PIN keeps the package and pinout but needs firmware work, and FUNC is functionally similar but may require a board or BOM change.
