Is there a pin-compatible replacement for B14B-XASK-1(LF)(SN)?

Not perfectly. While some 14-pin, single-row headers exist, they often have a 2.54mm pitch instead of 2.5mm. This small difference can cause mounting issues. Additionally, many alternatives are unshrouded, unlike the original JST part. Full datasheet and footprint review is essential.

What risks should I check before replacing B14B-XASK-1(LF)(SN)?

Key risks include: 1) Pitch mismatch (2.5mm vs 2.54mm) affecting PCB fit. 2) Mechanical form, especially shrouded vs. unshrouded headers, which impacts polarization and protection. 3) Electrical ratings, ensuring the replacement's current rating is sufficient.

B14B-XASK-1(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

The JST B14B-XASK-1(LF)(SN) is a 14-pin, single-row, 2.5mm pitch shrouded header. Finding a direct replacement requires matching the pin count, single-row configuration, 2.5mm pitch, and shrouded design.

AI replacement insight

Package riskhigh

Pitch and shroud differences require PCB and mating connector validation.

Electrical riskmedium

Some alternatives have lower current ratings, requiring circuit analysis.

Can it be replaced directly?

No direct, pin-to-pin compatible replacement for B14B-XASK-1(LF)(SN) was found. All candidates have significant differences in mechanical form or electrical ratings.

Best replacement path

Reviewing unshrouded 1x14 2.54mm pitch headers if the application can tolerate the lack of a shroud and slight pitch difference.

Main risk

The primary risk is mechanical incompatibility due to differences in pitch (2.5mm vs 2.54mm) and the presence or absence of a protective shroud.

Recommended alternatives

A 14-pin unshrouded header with matching electricals but different form factor and pitch; requires board-level verification.
