77313-422-48LF

Headers, Male Pins Overview

The 77313-422-48LF is a Bergstik® series vertical header connector manufactured by Amphenol ICC (FCI). It features 48 positions arranged in two rows with a 0.100" (2.54mm) pitch. Designed for through-hole mounting, it utilizes square male pins with gold or GXT™ contact plating on the mating side and tin plating on the tail. The connector supports a current rating of 3A per contact and operates within a temperature range of -65°C to 130°C. Constructed with black thermoplastic insulation rated UL94 V-0, it offers an unshrouded design suitable for board-to-board or cable applications.

Headers, Male Pins Feature Summary

• Provides reliable electrical interconnection via a 48-position, dual-row unshrouded header configuration.
• Features push-pull locking mechanism for secure board-to-board or cable connections.
• Utilizes phosphor bronze contacts with specified gold or tin plating for durability and conductivity.

Headers, Male Pins Applications

• Board-to-board interconnects in electronic equipment
• Mezzanine connections between circuit boards
• Memory card interconnect solutions
• Power-to-board connections

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to ensure correct pin length and plating options match the design requirements. Confirm that the unshrouded style aligns with the assembly space constraints. Check RoHS compliance status if restricted substances are a concern. Ensure the through-hole termination method is compatible with the manufacturing process. Validate the 3A current rating against the application's thermal profile.

Headers, Male Pins Selection Notes

Select this component when a high-density, low-profile vertical header is required for signal or power distribution. The 2.54mm pitch allows for standard spacing compatibility. Consider the unshrouded design for cost-sensitive or space-constrained layouts where guide rails are unnecessary. Evaluate the push-pull retention needs against other locking styles. Ensure the operating temperature range meets the environmental conditions of the final product.
