Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact part number suffix against official Fischer Elektronik documentation to confirm contact count and row configuration. Ensure compatibility with mating PC 104 headers regarding pin layout and mechanical tolerances. Confirm that the gold plating specification matches the application's conductivity requirements. Cross-reference thermal ratings with system operating environments to validate performance under heat stress.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a standardized PC 104 interface is required for space-constrained designs. The dual-row arrangement supports higher I/O density compared to single-row alternatives. Gold plating is essential for applications demanding long-term stability and low contact resistance. Verify that the through-hole footprint aligns with the target PCB manufacturing capabilities and drill specifications.

Headers, Receptacles, Female Sockets Part Context

This model belongs to the Fischer Elektronik BL 19 series, specifically engineered for PC 104 form factor applications. The series provides standardized interfaces for stacking electronic boards in compact enclosures. The BL 19 designation indicates a two-row configuration, distinguishing it from single-row variants. This specific part represents a 40-contact implementation within that structural family.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other Fischer Elektronik BL 19 series connectors with matching 40-pin counts and PC 104 compliance. Verify identical 2.54 mm pitch and gold-plated contact specifications. Ensure mechanical dimensions and termination type match the existing assembly constraints before substitution.
