Is there a pin-compatible replacement for BX-PM2.54-2-10PY?

There is no verified pin-to-pin replacement. While several candidates match the 2x10 2.54mm pitch layout, they have different electrical ratings or unconfirmed dimensions. You must review the datasheets to confirm pinout and footprint compatibility.

What risks should I check before replacing BX-PM2.54-2-10PY?

The main risk is electrical: ensure the alternative's lower voltage rating (e.g., 250V) is sufficient for your circuit, as the original part has a 1000V withstand rating. Also, check the mechanical drawing for housing height and pin length to ensure a proper fit.

AI replacement insight

Electrical riskhigh

Candidates have 250V-300V ratings vs. target's 1000V withstand. Unsuitable for high voltage applications.

Package risklow

Candidates match key mounting type, pitch, and pinout, but housing dimensions should be double-checked from datasheets.

Sourcing risklow

Multiple manufacturers produce similar 2.54mm headers, offering good availability of alternatives.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. Several functional alternatives exist but have a lower voltage rating and require engineering review.

Best replacement path

Use XKB Connection X6521FV-2x10-C85D32 or HanElectricity 2541FV-20P-B, but verify voltage requirements and mechanical drawings before purchasing.

Main risk

The primary risk is electrical; candidates have a significantly lower voltage rating. A secondary risk is minor mechanical differences in the housing or pin length.

Recommended alternatives

A strong alternative with matching form factor, but requires review of its lower voltage rating.
