Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required 21-position configuration and tin plating finish. Confirm compatibility with the target board's hole size and the mating connector's contact diameter of 0.635 mm. Ensure the through-hole mounting style aligns with the assembly process capabilities. Cross-reference the manufacturer datasheet for mechanical dimensions and thermal handling limits before finalizing procurement decisions.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, right-angle or straight header is needed for 2.54 mm pitch connections. The tin plating offers a balance between cost and performance for general-purpose signals. Consider the 0.635 mm contact diameter constraint during mechanical design. This series is suitable for applications where vertical space is limited but reliable through-hole retention is necessary.

Headers, Receptacles, Female Sockets Part Context

This component is part of the Fischer Elektronik BL LP 3 series, which focuses on low-profile fork contact female headers. The series is characterized by its ability to handle specific contact diameters while maintaining a compact form factor. Similar models in the range vary primarily by position count and orientation, sharing common design principles for precision interconnects.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same series include variants with different position counts, such as BL LP 3 22 Z or BL LP 3 36 Z, provided the mechanical footprint and pin pitch remain compatible. Verify that any replacement maintains the 0.635 mm contact diameter requirement and tin-plated finish to ensure functional equivalence.
