DEALON
A potential cross-vendor alternative with matching key electrical and mechanical specs; requires datasheet review.
A2508WV-4P is a common 4-pin, 2.5mm pitch vertical through-hole header. Several cross-vendor alternatives exist, but require careful verification of mechanical dimensions and footprint before substitution.
Mechanical dimensions (housing, pin length) must be verified from datasheets.
Key ratings (voltage, current) match across strong candidates.
No drop-in replacement is verified. However, several parts like ZX-XH2.54-4PZZ-Y are likely form-fit-function compatible after datasheet review.
Source a cross-vendor XH-style 2.5mm 4-pin vertical header like Megastar ZX-XH2.54-4PZZ-Y and verify mechanical drawings.
Mechanical incompatibility. While electrical specs match, housing dimensions and pin footprint can vary slightly between manufacturers.
