Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix and contact configuration against the official Fischer Elektronik datasheet before procurement. Ensure the required pin diameter matches the component specifications. Confirm that the through-hole mounting style aligns with the target PCB layout. Cross-reference the terminal plating and insulation material requirements with the project documentation to guarantee compatibility.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, single-row connector is required for 0.635 mm square pins. The 2.54 mm pitch allows for standard spacing on PCB layouts. Consider the 3 A current rating and 125 V voltage limits for circuit design. The fork contact design offers robust mechanical retention compared to standard spring fingers.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL series of PCB receptacles from Fischer Elektronik. The series is characterized by its use of stamped contact springs rather than coiled springs, offering a compact solution for board-to-board connections. These components are widely used in industrial electronics and consumer devices where space efficiency and connection stability are critical.

Headers, Receptacles, Female Sockets Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 2.54 mm pitch, 2-position count, and fork contact geometry. Verify mechanical dimensions and electrical ratings with alternative suppliers if sourcing from other manufacturers.
