Strong alternative with matching package, impedance, current rating, and automotive temperature range.
ACMA4532-510Y is an automotive-grade common mode filter in a 4532 (1812) package. Finding a replacement requires matching its 2800Ω typical impedance at 10MHz, 230mA current rating, and wide temperature range.
The top candidate (ACM4532F2NV-510T02-D) has matching electricals. Other candidates have high electrical risk.
Package size matches, but target's pinout is unverified. User must confirm layout compatibility.
Multiple manufacturers produce similar parts, but availability should be checked.
Direct replacement for ACMA4532-510Y should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The TAI-TECH ACM4532F2NV-510T02-D is a strong candidate, matching all key electrical and physical parameters.
The primary risk is ensuring the physical pinout matches, as the target's datasheet does not specify it. Parametric differences in other candidates, like lower impedance, pose a performance risk.

| Feature / factor | ACMA4532-510Y | ACM4532F2NV-510T02-D | ACMA4532-110Y | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 4532, null pins | 4532 (1812), 4-pin | 4532, 4-pin | 4532 (1812), 4-pin / 4532, 4-pin — Package matches. Target pin count is unverified but assumed to be 4.; ACMA4532-110Y: Package matches. | |
| Impedance | 1000Ω min, 2800Ω typ @ 10MHz | 1000Ω min, 2800Ω typ @ 10MHz | 600Ω typ @ 10MHz | 1000Ω min, 2800Ω typ @ 10MHz / 600Ω typ @ 10MHz — Impedance profile is a strong match.; ACMA4532-110Y: Significantly lower impedance will reduce filtering effectiveness. | |
| Current | 230mA | 230mA | 360mA | 230mA / 360mA — Rated current matches.; ACMA4532-110Y: Higher current rating provides more margin. | |
| Resistance | 1.0Ω max | 1.0Ω max | 0.6Ω max | 1.0Ω max / 0.6Ω max — DC resistance matches.; ACMA4532-110Y: Lower DCR is an improvement. | |
| Temperature | -55°C to +150°C | -55°C to +150°C | - | -55°C to +150°C — Automotive operating temperature range matches. |
Verified drop-in options for ACMA4532-510Y are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
