BL LP 4 40 Z

Headers, Receptacles, Female Sockets Overview

The BL LP 4 40 Z is a single-row male header connector manufactured by Fischer Elektronik. It features 40 positions with a 2.54 mm (0.100 inch) pitch, designed for through-hole PCB mounting. The contacts are tin-plated copper alloy pins with a square contact shape. The connector utilizes polyamide insulation material rated to UL 94 V-0 standards. Total contact length measures 11.20 mm, with a mating contact length of 5.40 mm and a column contact length of 3.00 mm. The insulator height is 2.80 mm.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number against official Fischer Elektronik documentation to confirm pin count and plating specifications. Ensure compatibility with mating socket connectors regarding pitch and housing dimensions. Check for RoHS compliance status if required by project regulations. Confirm surface mount versus through-hole requirements match the design layout.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 40-position single-row header is required for through-hole applications. The 2.54 mm pitch is standard for general-purpose electronics. Consider the tin plating thickness for solderability needs. Evaluate the operating temperature range against environmental conditions. Ensure the square pin shape aligns with available mating receptacles.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to Fischer Elektronik's BL series of rectangular headers. The series offers various position counts and mounting styles. The BL LP variant specifically denotes low-profile through-hole male pins. This family provides standardized dimensions for easy integration into existing designs.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other 40-position, 2.54 mm pitch through-hole male headers from manufacturers like Molex, TE Connectivity, or Samtec. Verify that replacement parts match the pin length, insulator height, and contact plating specifications. Ensure the mating interface geometry remains identical to avoid assembly issues.
