Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number suffix against official Fischer Elektronik documentation to confirm contact count and plating specifications. Ensure compatibility with mating pin diameters within the 0.635 mm to 0.85 mm range. Cross-reference datasheet revisions to confirm mechanical dimensions and mounting requirements before procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, 25-position female header is required for PC/104 or similar modular systems. Confirm that the mating hardware utilizes pins within the specified diameter tolerance. Evaluate through-hole mounting constraints and verify that the 2.54 mm pitch aligns with the target PCB layout design.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the BL 18 219 series of female headers manufactured by Fischer Elektronik. The series offers various contact counts ranging from one to thirty-six positions, all sharing the same 2.54 mm pitch and gold-plated contact construction. These connectors are specifically tailored for robust board-to-board applications requiring high reliability.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Fischer Elektronik BL 18 219 variants with matching contact counts, such as BL 18 219 24 or BL 18 219 26, provided the pin diameter tolerance remains compatible. Verify mechanical footprint and pin acceptance criteria before substitution.
