Pin-compatible 3-pin header from JST, the original XH series manufacturer, matching all key specs.
Find reliable substitutes for the HC-XH-3A-G, a 3-pin 2.5mm pitch straight header. Top alternatives include the original JST B3B-XH-A and other form-fit compatible options for your design.
Clones may have slight dimensional variations. Right-angle or bossed versions are not drop-in.
Voltage/current ratings are standard for this connector type and easily matched.
This is a very common connector style with many manufacturers and high availability.
Direct replacement for HC-XH-3A-G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for HC-XH-3A-G, then review parametric alternatives for package and electrical fit.
Mechanical mismatch is the primary risk. Verify pitch (2.50mm), orientation (straight), and features like mounting bosses before ordering.
