Official JST right-angle PCB header designed to mate with the XHP-3 housing.
Best Alternatives to XHP-3
JST's XHP-3 is a 3-position, 2.5mm pitch connector housing for the popular XH series. Finding a replacement requires understanding the entire connector system, including compatible crimp terminals and the various mating PCB headers available.
AI replacement insight
Package riskhigh
Target is a housing, candidates are headers. They are not interchangeable.
Sourcing riskmedium
Cross-vendor alternatives require careful mechanical validation before procurement.
Can it be replaced directly?
Direct replacement for XHP-3 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Identify the required PCB header (straight or right-angle, SMT or TH) that mates with the XHP-3 housing. The official JST part is S3B-XH-A (right-angle) or B3B-XH-A (straight). Then, select a mechanically compatible part from the XH 2.5mm family.
Main risk
The primary risk is confusing a housing with its mating header, leading to incorrect part selection. For headers, mechanical incompatibility (footprint, orientation) is the key risk.
