Excellent match with identical package, pitch, pin count, and a higher voltage rating. Review datasheet for pin length.
Find replacements for the CJT A2541HWV-2x12P, a 24-pin, 2.54mm pitch dual-row header. This guide reviews alternatives based on form, fit, and electrical parameters.
Key dimensions (pitch, rows) match on top candidates.
Top candidates have matching or superior ratings.
This is a common connector type with multiple vendors.
Direct replacement for A2541HWV-2x12P should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a form-fit-function match like HC-JN254-2-12-Z or ZX-PM2.54-2-12PY, which have the same 2.54mm pitch, 2x12 configuration, and 3A current rating.
The primary risk is a subtle mechanical mismatch in pin length or insulator dimensions that could affect assembly or mating connection.
