Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix and technical documentation against the manufacturer's current datasheet before procurement. Ensure that the required contact pins are sourced separately, as this header is designed for separable connections. Confirm compatibility with the intended PCB layout and mating connector specifications to guarantee proper mechanical fit and electrical performance in the final assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 70-position female header with a 2.64 mm pitch is required for 0.635 mm contacts. Consider the tin-plated contact surface and gold-plated sleeve for corrosion resistance and signal integrity. Evaluate the mechanical constraints of the application to ensure the separable design meets the insertion and extraction force requirements of the system architecture.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Fischer Elektronik BL LP series, which specializes in connectors for circuit boards and ribbon cables. The series includes various profiles and header configurations designed for robust electronic interconnections. The BL LP 4 70 Z represents a high-pin-count variant within this family, offering standardized spacing for consistent manufacturing processes across different electronic product lines.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 70-position count, and 0.635 mm contact diameter. Verify that alternative components offer compatible CuSn-alloy contacts and similar plating specifications (tin-plated contacts, gold-plated sleeves) to maintain electrical reliability and mechanical interchangeability without redesigning the PCB footprint.
