3-647078-3

Headers, Male Pins Overview

The TE Connectivity AMP Connectors part number 3-647078-3 is a vertical header connector belonging to the MTA-156 series. It features a 3-position configuration with a 2.54mm (0.100 inch) pin spacing. The connector utilizes through-hole termination for secure PCB mounting and employs a 1-wall shrouded design to ensure correct mating alignment. The contacts are tin-plated, providing reliable electrical conductivity and corrosion resistance suitable for general electronic applications.

Headers, Male Pins Feature Summary

• Vertical orientation facilitates compact board stacking
• Shrouded housing prevents incorrect insertion
• Through-hole termination ensures mechanical stability

Headers, Male Pins Applications

• General purpose circuit boards
• Industrial control systems
• Consumer electronics assemblies

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm contact plating thickness and insulation color requirements. Ensure the selected variant matches the intended current rating and voltage specifications for the target application environment. Cross-reference the RoHS compliance status if environmental regulations apply to the final product assembly.

Headers, Male Pins Selection Notes

Select this component when a low-profile vertical interconnect is required for signal transmission between PCBs or cable harnesses. The 2.54mm pitch is standard for prototyping and general wiring. Consider the shrouded design if polarized mating is necessary without additional mechanical keying features. Evaluate thermal dissipation needs as tin plating has lower conductivity than gold.

Headers, Male Pins Part Context

This connector is part of the broader MTA-156 family from TE Connectivity, designed for versatile wire-to-board and board-to-board connections. The series is known for its reliability in high-volume manufacturing environments. As an AMP brand product, it adheres to strict quality standards established by TE Connectivity for industrial and commercial electronic interconnections.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 3-position, 2.54mm pitch vertical headers from manufacturers like Molex or JST, provided they match the shrouding style and termination method. Verify that any alternative part maintains identical mechanical dimensions and electrical ratings to ensure seamless integration.
