Is there a pin-compatible replacement for XY2500R-B-5.00-4P?

While no replacement has been pre-verified as 100% pin-compatible, DB128V-5.0-4P-GN-S and DB127V-5.0-4P-GN-S are strong candidates. They share the same critical dimensions (4-pin, 5.0mm pitch) and are likely to be pin-compatible, but you must confirm the PCB footprint from the datasheets.

What risks should I check before replacing XY2500R-B-5.00-4P?

Before replacing, check three key areas: 1) Mechanical Fit: Ensure the candidate's PCB footprint and height match your design. 2) Electrical Ratings: Verify the voltage and current ratings are equal to or greater than the original's 300V/15A. 3) Wire Gauge: Confirm the replacement accepts your required wire size.

XY2500R-B-5.00-4P is a standard 4-position, 5.0mm pitch wire-to-board terminal block rated for 300V and 15A. Several functional alternatives are available from other manufacturers, with some offering identical or improved electrical specifications.

AI replacement insight

Electrical risklow

Strong candidates match or exceed voltage/current ratings. Downgrade options exist and must be carefully evaluated.

Package riskmedium

While pitch and position count match on good candidates, slight variations in body dimensions or pin length are possible and require datasheet review.

Sourcing risklow

This is a common connector type with multiple manufacturers, suggesting good availability of alternatives.

Can it be replaced directly?

No direct, datasheet-verified pin-to-pin replacement has been confirmed. However, DB128V-5.0-4P-GN-S and DB127V-5.0-4P-GN-S are strong candidates for form, fit, and function compatibility, pending user verification of the mechanical drawings.

Best replacement path

DB128V-5.0-4P-GN-S is the strongest candidate, offering a slightly higher current rating with matching form factor. DB127V-5.0-4P-GN-S is also a strong choice with identical electricals. Both require mechanical drawing verification.

Main risk

The primary risks are electrical downgrades (lower current or voltage) in some alternatives and ensuring the mechanical footprint and pinout are identical.

Recommended alternatives

A strong alternative with matching form, pitch, voltage, and a slightly higher current rating.
