BL 20 SMD 4 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 BL 20 SMD 4 is a female header connector manufactured by Fischer Elektronik, designed for surface-mount technology (SMT) applications. It features a 2.54 mm pitch and provides four contacts. The contact sleeves are tin-plated, while the contact springs are gold-plated to ensure reliable signal transmission. The contact material consists of a CuZn alloy, offering mechanical stability and conductivity. This component is engineered for high-density electronic assemblies, providing a compact and robust connection solution suitable for PCB integration.
Verify the specific ordering suffix against official Fischer Elektronik documentation to confirm pin count and plating specifications. Ensure compatibility with standard SMT reflow processes. Cross-reference the datasheet for precise mechanical dimensions and thermal handling limits before procurement to prevent assembly mismatches.
Select this component when a low-profile, four-position female header is required for surface-mount implementation. The 2.54 mm pitch aligns with standard ribbon cable and wire harness systems. Consider the gold-plated springs for environments requiring frequent mating cycles or high reliability standards.
This part belongs to the BL 20 SMD series, which includes variants with different contact counts such as the BL 20 SMD 48. Fischer Elektronik specializes in connectors and heat sinks, establishing this product within their portfolio of precision-engineered electronic components for industrial and consumer electronics.
Consult official Fischer Elektronik substitution guides for direct equivalents. Generic headers may differ in spring tension or plating thickness. Verify that alternative parts match the 2.54 mm pitch and SMT footprint to ensure mechanical fit and electrical performance.
