XH-3A-P
HCTL
Needs validationlow risk
Strong functional alternative with matching key electrical and mechanical specs. Requires datasheet review for footprint confirmation.
Best Alternatives to XD-XH-3A-G
XD-XH-3A-G is a standard 3-pin, 2.5mm pitch through-hole header used for wire-to-board connections. Many manufacturers produce functionally similar connectors, often as part of the popular XH series.
AI replacement insight
Package riskmedium
Housing and footprint dimensions must be verified from datasheets.
Electrical risklow
Most candidates have matching voltage and current ratings.
Sourcing risklow
This is a common connector type with many available manufacturers.
Can it be replaced directly?
No direct drop-in replacement is confirmed. However, parts like HCTL XH-3A-P are strong candidates that require a datasheet review to verify mechanical fit.
Best replacement path
Cross-reference to other manufacturers' XH series 3-pin straight headers, such as HCTL XH-3A-P or ZHOURI XH-3PA.
Main risk
Minor differences in mechanical dimensions (housing, pin length, footprint) could prevent a successful substitution.
