Is there a pin-compatible replacement for 533980671?

While several 'PicoBlade style' clones exist, like ZX-MX1.25-6PLT, true pin-compatibility must be confirmed by comparing the datasheet's mechanical drawing with the Molex original. No candidate is verified as a drop-in replacement without this check.

What risks should I check before replacing 533980671?

Key risks include: 1) Mechanical footprint mismatch preventing proper PCB assembly. 2) Mating incompatibility with existing PicoBlade wire housings. 3) Different electrical ratings, such as lower voltage, that could compromise safety or performance.
