BL 5 31 is listed in the Headers, Receptacles, Female Sockets range at ChipApex. The manufacturer field lists Fischer Elektronik. Its product description is for 0.635 mm and up to 0.85 mm. Review the specifications below when checking this part for your BOM.
The Fischer Elektronik BL 5 31 is a 31-position female header connector designed for through-hole PCB mounting. It features a 2.54 mm pitch and utilizes copper-zinc alloy contacts with tin-plated sleeves. The inner contact spring surface is nickel-plated with a gold coating of at least 0.75 µm, ensuring reliable electrical performance for wire diameters ranging from 0.635 mm up to 0.85 mm.
Verify the specific product variant against official datasheets to confirm contact plating specifications and mechanical dimensions. Ensure compatibility with mating pins regarding diameter constraints. Cross-reference part numbers with manufacturer documentation to distinguish between standard and ECO versions if applicable.
Select this component when a high-density 31-position female header is required for through-hole applications. Consider the 2.54 mm pitch constraint and verify that the target wire or pin diameter falls within the specified 0.635 mm to 0.85 mm range. Evaluate the gold-plated contact surface requirements for long-term reliability in the intended operating environment.
The BL 5 series represents Fischer Elektronik's line of female headers engineered for robust electronic connections. This specific model belongs to a family of connectors characterized by standardized pitches and durable contact materials, serving as a fundamental interconnection solution in various hardware designs.
Consult official substitution lists for equivalent 31-position female headers with matching 2.54 mm pitch and through-hole mounting. Verify mechanical footprint and contact material compatibility before replacing.
