Is there a pin-compatible replacement for XHP-4?

No, there is no pin-compatible replacement because XHP-4 is a connector housing, not a PCB-mounted part. You should look for a mating header, such as S4B-XH-A(LF)(SN), which connects to the XHP-4.

What risks should I check before replacing XHP-4?

The main risks are mechanical and electrical. First, ensure the header's PCB footprint (e.g., through-hole vs. SMT) matches your board design. Second, verify that the voltage and current ratings of the alternative header meet or exceed the JST original's 250V/3A specification.

XHP-4 Alternatives, Datasheet & Cross Reference | JST

The JST XHP-4 is a popular 4-position, 2.5mm pitch connector housing. While it is not directly replaced, it pairs with many compatible male headers, with the official JST S4B-XH-A(LF)(SN) being the recommended mating part for new designs.

AI replacement insight

Package riskhigh

Mating headers can be Through-Hole or SMT, requiring different PCB layouts. Footprint must be verified for non-JST parts.

Electrical riskmedium

Cross-vendor parts may have lower voltage or current ratings. This must be verified from the datasheet.

Sourcing riskmedium

Generic part numbers like 'XHB-4A' have inconsistent specs across vendors, creating a high risk of ordering the wrong part.

Can it be replaced directly?

There is no direct replacement for the XHP-4 housing itself. The best option is to use a compatible mating header from the JST XH series to complete the connection.

Best replacement path

Use the official JST mating header S4B-XH-A(LF)(SN) for a reliable right-angle, through-hole connection that is guaranteed to be compatible.

Main risk

Using non-JST compatible headers risks mechanical incompatibility with the PCB footprint or lower electrical ratings (voltage/current) that could compromise safety.

Recommended alternatives

Official JST right-angle through-hole header that mates with the XHP-4 housing, sharing key electrical ratings.
