Is there a pin-compatible replacement for XY2500F-B-5.08-2P?

No replacement can be guaranteed as pin-compatible without datasheet verification of all mechanical dimensions. However, MX129-5.08-02P-GN01-Cu-Y-A is a very strong form-fit-function match that is likely inter-mateable.

What risks should I check before replacing XY2500F-B-5.08-2P?

Before replacing, you should verify three main things: 1) The candidate is a female plug, not a male header. 2) The wire entry angle (horizontal vs. vertical) fits your design's space constraints. 3) The candidate is mechanically compatible with the male header on your PCB.

AI replacement insight

Electrical risklow

Candidates have matching or superior voltage and current ratings.

Package riskmedium

While pitch and position match, subtle differences in housing or mating interface between vendors are possible. One candidate has a different wire entry angle.

Can it be replaced directly?

Yes, MX129-5.08-02P-GN01-Cu-Y-A is a strong candidate for a direct replacement, offering an upgrade in current rating. However, as with any cross-vendor replacement, verifying subtle mechanical tolerances and mating force is recommended.

Best replacement path

The MAX MX129-5.08-02P-GN01-Cu-Y-A is the strongest alternative, offering a higher current rating with a matching form factor. The XINLAIYA XY128V-A-5.08-2P is also compatible but has a different wire entry angle.

Main risk

The primary risk is ensuring mechanical compatibility, including the mating interface with the corresponding PCB header and the wire entry orientation for cable routing.

Recommended alternatives

This MAX connector is a strong functional alternative with a higher 20A current rating and matching form factor.
