A1254WR-S-6P
CJT
Needs validationmedium risk
Strong functional alternative with matching electrical ratings and wider temperature range; pinout requires verification.
Best Alternatives to ZX-GH1.25-WT6
Finding a substitute for the Megastar ZX-GH1.25-WT6 6-pin header involves matching the 1.25mm pitch and right-angle SMT format. The primary challenge is verifying the PCB footprint for pin-to-pin compatibility.
AI replacement insight
Package riskmedium
High risk until the PCB footprint is verified from the datasheet. Form factor (SMT, RA) matches.
Electrical risklow
The best candidate (A1254WR-S-6P) matches or exceeds all key electrical ratings.
Can it be replaced directly?
Direct replacement for ZX-GH1.25-WT6 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
