Is there a pin-compatible replacement for XY308-2.54-4P?

No replacement is confirmed as 100% pin-compatible without a detailed dimensional check. The MAX MX128-2.54-04P-GN01-Cu-Y-A is a strong candidate for form, fit, and function, making it the most likely to be pin-compatible, but verification is essential.

What risks should I check before replacing XY308-2.54-4P?

The main risk is a mechanical mismatch of the PCB footprint, which could prevent assembly. Also, check for functional differences, such as the wire termination method (e.g., screw-clamp vs. spring-cage), which could affect usability.

AI replacement insight

Package riskmedium

Pin-to-pin footprint is not guaranteed across vendors and must be verified from datasheets.

Electrical risklow

Candidates with matching voltage and current ratings are available, minimizing electrical stress risk.

Sourcing riskmedium

Availability and lead time of alternatives should be checked with distributors.

Can it be replaced directly?

No verified direct drop-in replacement is available. The MAX MX128... is a strong form, fit, and function candidate that requires engineering review of the PCB layout.

Best replacement path

The MAX MX128-2.54-04P-GN01-Cu-Y-A is the most promising path, matching all key electrical ratings and the screw-terminal function.

Main risk

The primary risk is a mismatch in the PCB pin-out and mechanical footprint, which could prevent assembly.

Recommended alternatives

A 4-position, 2.54mm pitch terminal block with matching 150V/6A rating. Verify PCB footprint before use.
