Procurement Notes
Verify the specific suffix 'P' against official datasheets to confirm packaging details, as distributor listings may vary. Ensure compatibility with mating male headers from the same Gecko-SL family. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this part for applications requiring high-density vertical interconnects on limited board space. The 1.25 mm pitch allows for compact layouts compared to larger spacing options. Verify that the target PCB footprint matches the surface mount terminal specifications provided in the official mechanical drawings.
Part Context
This component belongs to the Harwin Gecko-SL series, which focuses on high-reliability power distribution. The series offers various configurations including through-hole and surface mount options. The Gecko-SL line is engineered for demanding environments, providing robust mechanical retention and electrical stability across diverse industrial sectors.
Replacement Considerations
Direct substitutes within the Gecko-SL family include G125-FS11005F2R and G125-FS12005L0P. Verify pin count and mounting style compatibility before substitution. Cross-reference mechanical dimensions to ensure fit within existing enclosure constraints.
