BL LP 4 54 S

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL LP 4 54 S is a precision-engineered header connector designed for applications requiring contacts with a diameter of 0.635 mm. It features 54 positions with a 2.54 mm pitch, utilizing selective gold-plated contacts on the mating surface and nickel plus minimum 5 µm plating on the contact sleeve. The component is constructed from CuSn-alloy contacts and is intended for through-hole mounting.

Headers, Receptacles, Female Sockets Feature Summary

• Precision design for 0.635 mm contact diameter compatibility
• Selective gold plating on mating surfaces for reliable connection
• Nickel base with minimum 5 µm coating on contact sleeves

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnects requiring specific contact diameters
• High-density PCB assemblies using 0.635 mm pins
• Electronic equipment needing robust header connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the application circuit utilizes contacts with a 0.635 mm diameter to ensure mechanical compatibility. Confirm that the required current rating aligns with the connector's specifications, as detailed in the official datasheet. Ensure the PCB layout accommodates the 2.54 mm pitch and the specific pin count of 54 positions without obstruction.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when the system design mandates a 0.635 mm contact interface rather than standard sizes. The selective gold plating offers superior conductivity and corrosion resistance compared to tin-only options. Consider the physical dimensions and mounting requirements to ensure it fits within the designated space constraints of the assembly.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the BL LP 4 series, which specializes in connectors for non-standard 0.635 mm contact diameters. Unlike standard 2.54 mm pitch headers that accept 1.0 mm or 1.27 mm pins, this series ensures precise alignment and secure mating for specialized hardware interfaces requiring tighter tolerances.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 54-position count, 2.54 mm pitch, and 0.635 mm contact diameter requirement. Verify that any alternative maintains the selective gold plating specification to preserve electrical performance and reliability standards equivalent to the original part.
