Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct pin count and orientation. Confirm that the tin plating specification meets the environmental requirements of the target application. Cross-reference the package dimensions with the intended PCB footprint to guarantee proper assembly alignment and clearance.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 42-position through-hole header with 2.54 mm spacing is required. Ensure the operating temperature range aligns with the system environment. Consider the mechanical stability provided by the through-hole design versus surface mount alternatives if space constraints exist.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 4 series of precision connectors from Fischer Elektronik. The series utilizes stamped spring contacts for durability. Similar models in the lineup vary primarily by position count and orientation, such as right-angle configurations, while maintaining consistent pitch and mounting characteristics.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 42-position, 2.54 mm pitch through-hole headers from Fischer Elektronik, such as the BL 4 72 Z for higher density needs. Verify compatibility with mating pins before substitution.
