311-87-140-41-001101

Headers, Receptacles, Female Sockets Overview

The Preci-Dip 311-87-140-41-001101 is a single-row socket connector designed for through-hole mounting on printed circuit boards. It features forty positions with a 2.54 mm pitch, accommodating standard pin headers. The contacts are constructed from copper beryllium alloy and finished with gold plating on the mating interface to ensure reliable conductivity. Tin plating is applied to the termination pins for soldering compatibility. The housing utilizes glass-reinforced PCT material, rated UL94 V-0 for flammability, supporting operation between -55°C and 125°C with a 3A current rating.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number against official manufacturer catalogs to confirm availability and lead times. Ensure that the required contact count and pitch match the design specifications before ordering. Cross-reference the insulation material and temperature ratings with environmental requirements. Confirm compliance with relevant safety standards if applicable to the end application.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, forty-position through-hole socket is required. Verify that the 2.54 mm pitch aligns with the mating header dimensions. Consider the 3A current rating and operating temperature range relative to the circuit load. Evaluate the need for gold versus tin contact finishes based on environmental exposure and cycle life expectations.

Headers, Receptacles, Female Sockets Part Context

This model belongs to the Preci-Dip 311 series of rectangular connectors. The series offers various position counts and orientation options. The 311-87 suffix typically denotes a socket variant with specific termination and housing characteristics within the broader product line.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 311-series sockets with identical pin counts and pitch, such as 311-87-140-41-001101 variants with different plating thicknesses. Alternative manufacturers offering 2.54 mm pitch single-row sockets may be considered if dimensional compatibility is verified.
