• Compatible with 0.635 mm square profile circuit points
• Supports plugability for circuit point dimensions of 0.50 mm and 0.70 mm

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnection systems
• Through-hole PCB connection assemblies
• Electronic component integration requiring fork contact profiles

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix and pin configuration against the official Fischer Elektronik datasheet before procurement. Ensure that the required contact plating and insulation color match the project specifications. Confirm mechanical compatibility with the target 0.635 mm square profile and verify that the through-hole mounting style aligns with the printed circuit board design requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 20-position straight header with a 2.54 mm pitch is required for through-hole assembly. Consider the tin-plated contact finish for general-purpose applications where corrosion resistance is sufficient. Evaluate the mechanical force requirements, noting the 1.5 N insertion force, to ensure compatibility with automated placement equipment and manual handling processes within the manufacturing workflow.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 1 series, which focuses on precision-engineered stamped contact springs. The series is characterized by its suitability for fork contact applications and compatibility with specific square profile dimensions. Fischer Elektronik, founded in 1969, specializes in PCB connection systems, offering components that integrate mechanical stability with precise electrical connectivity for various industrial electronic assemblies.

Headers, Receptacles, Female Sockets Replacement Considerations

Cross-reference with other Fischer Elektronik headers such as the BL LP 1 20 Z for similar form factors. Verify that alternative suppliers provide connectors with identical 2.54 mm pitch and 20-position count. Ensure that any substitute maintains the same through-hole mounting style and compatible fork contact profile dimensions for mechanical interchangeability.
