Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, plating type, and mounting style. Ensure compatibility with standard 2.54 mm grid footprints during PCB layout. Confirm RoHS compliance status if required by project specifications. Cross-reference the full part number with Fischer Elektronik catalogs to avoid confusion with similar header or socket variants.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, surface-mount solution is required for connecting two parallel PCBs. The 0.635 mm contact diameter offers robust mechanical retention compared to finer pitches. Consider the single-row configuration for space-constrained layouts where vertical clearance is limited. Validate thermal requirements and mating cycle expectations against the tin-plated contact specifications.
