Is there a pin-compatible replacement for B06B-XASK-1N(LF)(SN)?

Potentially, but this requires careful verification. While some parts have an identical PCB footprint (form-fit), differences in connector series (XA vs. XH) mean mating connectors are not interchangeable. True pin-to-pin compatibility is not guaranteed without comparing mechanical drawings.

What risks should I check before replacing B06B-XASK-1N(LF)(SN)?

The main risk is mechanical incompatibility. Check the PCB footprint dimensions, header height, and keying. Crucially, ensure your mating connector housing is compatible with the replacement header's series (e.g., XH series), as it will differ from the original XA series.

B06B-XASK-1N(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

The JST B06B-XASK-1N(LF)(SN) is a 6-pin, 2.5mm pitch straight through-hole header from the XA series, rated for 3A and 250V. Finding a direct replacement requires matching the XA series' specific mechanical footprint and locking features.

AI replacement insight

Package riskmedium

Footprint may be similar, but housing dimensions, keying, and locking features differ.

Electrical risklow

Voltage and current ratings are identical.

Can it be replaced directly?

No direct, verified drop-in replacement has been identified. Several functional alternates exist but belong to the JST XH series, which has different housing and locking features than the target's XA series.

Best replacement path

Find a straight, 6-pin, 2.5mm pitch header and verify its mechanical drawing against the B06B-XASK-1N(LF)(SN) datasheet for footprint compatibility.

Main risk

Mechanical incompatibility due to connector series mismatch (XA vs. XH), affecting both PCB footprint and mating connector compatibility.

Recommended alternatives

A 6-pin, 2.5mm pitch straight header with same ratings, but from a different connector series requiring mechanical verification.

Questions & answers

Alternatives like HC-XH-6A-G exist with the same pin count, pitch, and orientation. However, they are from the XH series, which is not directly mate-compatible with the target's XA series. PCB footprint and mechanical fit must be verified via datasheet comparison.
