504385-E

Headers, Male Pins Overview

The TE Connectivity Erni 504385-E is a MicroBridge series pin header connector designed for surface mount applications. It features a 4-position, single-row configuration with a 1.27mm (0.050 inch) mating pitch. The component utilizes square male pins with gold-plated mating surfaces and tin-plated tails, housed in black liquid crystal polymer (LCP). Rated for 3.7A per contact, it operates within a temperature range of -40°C to 150°C and meets UL94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Surface mount right-angle or straight design compatible with automated pick-and-place assembly processes
• Four-wall shielding structure provides electromagnetic interference protection
• Gold-plated contacts ensure reliable signal transmission in board-to-board connections

Headers, Male Pins Applications

• Automotive electronic control units requiring robust surface mount interconnects
• Industrial control systems utilizing MicroBridge connector families
• Board-to-board connections in compact electronic assemblies

Headers, Male Pins Procurement Notes

Verify the specific orientation suffix in the part number to confirm straight versus right-angle mounting requirements. Ensure compatibility with the corresponding MicroBridge receptacle series for proper mating. Confirm that the surface mount footprint matches the target PCB layout specifications before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, shielded surface mount header is required for high-reliability applications. The 1.27mm pitch allows for dense circuit board layouts while maintaining adequate spacing. Consider the operating temperature range and current rating to ensure suitability for the specific environmental conditions of the end-use application.

Headers, Male Pins Part Context

This connector belongs to the MicroBridge family, which is widely used in automotive and industrial sectors. The series offers various positioning options and shielding configurations to meet diverse connectivity needs. The 504385-E specifically addresses the need for compact, shielded headers in space-constrained designs.

Headers, Male Pins Replacement Considerations

Compatible counterparts within the same MicroBridge series should be evaluated for mechanical and electrical equivalence. Verify that alternative parts maintain the same 1.27mm pitch and shielding characteristics to ensure seamless integration without redesigning the host PCB.
