XH-D-3A
DEALON
Needs validationmedium risk
This DEALON part is a strong functional match with identical key electrical ratings, pitch, and pin count.
Best Alternatives to XH-3PA
XH-3PA is a common 3-pin, 2.5mm pitch through-hole header. Several manufacturers offer form, fit, and functionally similar parts within the XH connector family, providing multiple sourcing options.
AI replacement insight
Package risklow
High likelihood of compatibility within the XH series, but datasheet verification is necessary for footprint.
Electrical risklow
Most alternatives match the 250V/3A rating, but this must be confirmed for each candidate.
Sourcing risklow
This is a very common connector type with a large number of suppliers.
Can it be replaced directly?
Yes, several manufacturers produce 3-pin, 2.5mm pitch headers that are strong functional alternatives to XH-3PA. However, pin-to-pin compatibility requires verifying mechanical drawings.
Best replacement path
Use cross-vendor XH-series parts like DEALON XH-D-3A or Megastar ZX-XH2.54-3PZZ-Y after verifying mechanical dimensions.
Main risk
The primary risk is minor mechanical differences in housing or pin dimensions between manufacturers, which could affect PCB fit or mating.
