77311-122-09LF

Headers, Male Pins Overview

The Amphenol ICC (FCI) 77311-122-09LF is a BergStik® series vertical board-to-board header connector. It features a single row of nine male pin contacts with a 2.54mm pitch. Designed for through-hole mounting, the unit utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the termination column. The housing is constructed from black thermoplastic material rated UL94 V-0 for flammability.

Headers, Male Pins Feature Summary

• Vertical orientation facilitates direct board-to-board stacking connections
• Push-pull locking mechanism ensures secure mating retention
• Gold-plated contact surfaces provide reliable signal transmission
• Thermoplastic insulation offers structural stability and fire resistance

Headers, Male Pins Applications

• Board-to-board interconnects in industrial control systems
• Signal routing within factory automation equipment
• Connections in instrumentation and measurement devices
• Interface modules for heavy equipment control units

Headers, Male Pins Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Amphenol documentation. Confirm that the specific suffix indicates the required contact configuration and plating specifications. Ensure compliance with project environmental standards regarding material composition and RoHS directives before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this connector when a vertical, unshrouded header with a 2.54mm pitch is required for rigid board connections. Consider the 3A current rating per contact and the -65°C to 125°C operating temperature range against system thermal requirements. Evaluate the through-hole termination style against available PCB fabrication capabilities and mechanical stress constraints.

Headers, Male Pins Part Context

This component belongs to the BergStik® family of 2.54mm pitch connectors manufactured by Amphenol ICC (FCI). The series provides standardized vertical headers suitable for general-purpose electronic assemblies. The 77311 base numbering identifies the specific header geometry and contact arrangement within the broader product portfolio.

Headers, Male Pins Replacement Considerations

Consult official Amphenol substitution guides for verified equivalent part numbers. Verify that any alternative maintains identical pitch, row count, and mounting orientation. Ensure compatibility with existing mating receptacles and PCB footprint dimensions before implementation.
