147377-4

Headers, Male Pins Overview

The 147377-4 is a surface mount header connector from the AMPMODU System 50 series, manufactured by TE Connectivity AMP Connectors. It features 40 positions arranged in a dual-row configuration with a 1.27 mm (0.050 inch) mating pitch and a 2.54 mm (0.100 inch) row spacing. The connector utilizes gold-plated contacts with a thickness of 30.0 µin (0.76 µm) on the mating interface and tin plating on the tail, housed in black polyphthalamide insulation rated UL94 V-0. Designed for board-to-board or cable applications, it operates within a temperature range of -65°C to 105°C and supports a maximum voltage of 30VAC.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel quantities or cut tape options, as these affect handling procedures. Ensure the requested variant matches the required pin count and shroud configuration. Cross-reference the manufacturer part number against official TE Connectivity databases to confirm current availability status and any recent product change notices that may impact long-term supply.

Headers, Male Pins Selection Notes

Select this component when high-density interconnection is required with precise alignment constraints. The dual-row layout maximizes connection density while maintaining standard board spacing compatibility. Consider the operating temperature range and flammability rating to ensure compliance with environmental standards. Verify that the mating receptacle matches the 1.27 mm pitch and shrouded geometry to prevent misalignment during insertion.

Headers, Male Pins Part Context

This component belongs to the AMPMODU System 50 family, a widely used line of rectangular connectors known for their reliability in harsh environments. The system offers various configurations including headers, receptacles, and terminals. The 147377-4 specifically addresses the need for robust surface-mount solutions in compact designs where space efficiency and secure locking mechanisms are critical for maintaining connection integrity under vibration.

Headers, Male Pins Replacement Considerations

Direct substitutes include other 40-position, 1.27mm pitch SMD headers from compatible families, provided mechanical dimensions and shroud styles match exactly. Verify that alternative parts maintain the same contact material specifications and insulation ratings. Check for pinout compatibility if the replacement involves different series within the same manufacturer's portfolio.
