Is there a pin-compatible replacement for B4P-VH-B(LF)(SN)?

A direct, pin-compatible replacement is not identified in this list. The closest part, B4P-VH-FB-B(LF)(SN), is electrically identical but has a different PCB footprint due to mounting bosses. Other candidates have different orientations or lower current ratings.

What risks should I check before replacing B4P-VH-B(LF)(SN)?

Key risks include: 1) Mechanical Fit: Ensure the replacement has a straight (vertical) orientation, not right-angle. 2) PCB Footprint: Check for differences like mounting bosses. 3) Electrical Rating: Verify the current rating is 10A or higher.

B4P-VH-B(LF)(SN) Alternatives, Datasheet & Cross Reference | JST

The JST B4P-VH-B(LF)(SN) is a popular 4-pin, 3.96mm pitch straight header from the VH series, rated for 10A and 250V. Finding a direct replacement requires matching the straight orientation and current rating.

AI replacement insight

Package riskhigh

Many candidates have the wrong orientation (right-angle). Close matches may have different footprints (e.g., mounting bosses).

Electrical riskmedium

Some mechanically similar parts have lower current ratings, requiring application-level analysis.

Can it be replaced directly?

No direct drop-in replacement was found. All viable alternatives require engineering review for either mechanical footprint or electrical rating differences.

Best replacement path

Verify JST's B4P-VH-FB-B(LF)(SN) for footprint compatibility or select HC-VH-4ALT if a 7A current rating is acceptable.

Main risk

Mechanical incompatibility due to mounting orientation or PCB footprint differences is the primary risk, followed by electrical downgrade.

Recommended alternatives

Electrically identical alternative from the same manufacturer, but requires PCB footprint review due to added mounting bosses.
