Is there a pin-compatible replacement for MX128-5.08-04P-GN01-Cu-Y-A?

No pin-compatible replacement has been confirmed without datasheet verification. Candidates like XY2500V-D-5.08-4P share the same pitch and pin count, making them strong candidates, but require a mechanical check.

What risks should I check before replacing MX128-5.08-04P-GN01-Cu-Y-A?

Before replacing, you must verify the mechanical dimensions (footprint, height) from the datasheet. Also, confirm the connector style; the target is pluggable, and some alternatives may be fixed blocks.

MX128-5.08-04P-GN01-Cu-Y-A Alternatives, Datasheet & Cross Reference | Cybermax

MX128-5.08-04P-GN01-Cu-Y-A is a 4-position, 5.08mm pitch pluggable terminal block rated for 300V and 10A. Finding a suitable replacement requires careful comparison of mechanical drawings.

AI replacement insight

Package riskmedium

While pitch and position count match, overall dimensions and pinout must be verified from datasheets.

Electrical risklow

Candidates meet or exceed the target's voltage and current ratings, posing minimal electrical risk.

Can it be replaced directly?

No confirmed direct drop-in replacement has been identified. Several functional alternatives exist but require datasheet review to confirm mechanical fit and style.

Best replacement path

XY2500V-D-5.08-4P and DB2EK-5.08-4P-GN-S are strong candidates with upgraded current ratings. They require mechanical verification.

Main risk

The primary risk is mechanical incompatibility. This includes PCB footprint, height, and whether the connector is a fixed or pluggable type.

Recommended alternatives

This 4-position, 5.08mm pitch terminal block offers a higher current rating of 15A. Review datasheet for mechanical compatibility.
