Is there a pin-compatible replacement for ZX-XH2.54-5PWT?

No pin-compatible SMT replacement has been verified. All identified candidates have a different mounting type (Through-Hole instead of Surface Mount), which makes them incompatible with the existing PCB footprint.

What risks should I check before replacing ZX-XH2.54-5PWT?

The primary risk is mechanical incompatibility. The target is a Surface Mount (SMT) right-angle header. All potential alternatives are Through-Hole, requiring a complete PCB layout and assembly process change. Verify the connector orientation (straight vs. right-angle) as well.

ZX-XH2.54-5PWT Alternatives, Datasheet & Cross Reference | Megastar

ZX-XH2.54-5PWT is a 5-pin, 2.5mm pitch, right-angle SMT header from Megastar. While no direct drop-in replacements are identified, several functional alternatives with different mounting types exist that require board redesign.
