76385-314LF Male Pin Header

Updated: 2026-08-10

Overview

The 76385-314LF Male Pin Header is a standardized connector widely used in electronics manufacturing. It belongs to the 76385 series by a major component manufacturer, designed for through-hole PCB mounting. These headers facilitate reliable interconnections in devices ranging from industrial controls to consumer electronics. The 'LF' suffix indicates lead-free compliance, adhering to RoHS environmental standards. Typical applications include board-to-board connections, cable assemblies, and test equipment interfaces. Its design prioritizes mechanical stability and consistent electrical performance across temperature variations.

Structure and Working Principle

This pin header consists of precision-machined metal pins (commonly brass) housed in an insulated thermoplastic frame. The pins are gold-plated to reduce contact resistance and prevent oxidation. The 314 designation typically refers to specific dimensional characteristics like pitch and row configuration. When mated with a female socket, the pins establish electrical continuity through spring-loaded contact pressure. The housing features polarization slots to prevent incorrect insertion. Some variants include locking mechanisms for vibration-resistant applications in automotive or aerospace systems.

Key Features

The 76385-314LF offers several technical advantages: a 3A current rating per contact, operating temperatures from -55°C to +105°C, and an insertion durability exceeding 500 cycles. The gold plating (0.76μm min) ensures stable contact resistance below 20mΩ. Mechanically, the nylon housing provides UL94V-0 flame resistance while maintaining dimensional stability. Pin retention force exceeds 2.5N, preventing dislodgment during assembly. Compatible with wave soldering and reflow processes, it supports both manual and automated PCB population methods.

Application Areas

Primary use cases include industrial automation controllers, medical monitoring devices, and telecommunications infrastructure. The connector's reliability makes it suitable for harsh environments when paired with appropriate shrouded headers. In consumer electronics, it appears in smart home hubs and appliance control boards. Automotive applications require specialized variants with higher vibration resistance. The open-frame design allows for custom pin configurations during PCB layout for prototyping or low-volume production.

Maintenance and Precautions

Prevent contamination by storing in anti-static packaging until use. During PCB assembly, ensure solder wets the entire pin circumference without bridging adjacent contacts. For high-vibration environments, apply adhesive strain relief to cable connections. Inspect for bent pins prior to installation using a magnifier. Never force-mate connectors beyond rated insertion force. For field repairs, use extraction tools specifically designed for pin headers to avoid damaging PCB vias during component replacement.

B2B Procurement Guide

Industrial buyers should verify manufacturer certifications (e.g., ISO 9001) and request material composition reports for regulated industries. Minimum order quantities typically start at 1,000 pieces, with price breaks at 10k+ units. Key procurement considerations include lead time (commonly 6–8 weeks for custom configurations), packaging options (tape-and-reel vs. bulk), and compliance documentation. For high-reliability applications, request sample testing data including thermal cycling and humidity resistance reports.
