7-146259-4

Overview

The 7-146259-4 is a rectangular connector header from the AMPMODU Mod II series, manufactured by TE Connectivity AMP Connectors. It features a 48-position configuration with a 0.100-inch (2.54mm) pin spacing and double-row arrangement. Designed for through-hole termination, this male pin header utilizes tin-plated contacts and liquid crystal polymer insulation rated UL94 V-0. The component supports a maximum current rating of 3A and operates within a temperature range of -65°C to 105°C.

Feature Summary

• Double-row board-to-board or cable interconnect design
• Through-hole solder termination for secure mounting
• Tin-plated copper alloy contacts for conductivity
• UL94 V-0 flame retardant liquid crystal polymer housing

Applications

• General purpose electronic circuit board interconnections
• Signal transmission in industrial control systems
• Data routing in telecommunications equipment

Procurement Notes

Verify the specific contact plating material and terminal availability before integration, as manufacturing updates may affect compliance requirements. Confirm that the through-hole footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the specified thermal limits to maintain signal integrity and mechanical stability during service life.

Selection Notes

Select this component when a robust, double-row male header is required for high-density board stacking or cabling applications. The 2.54mm pitch ensures compatibility with standard wiring harnesses and mating sockets. Consider the 3A current capacity and wide temperature range for demanding operational environments requiring reliable electrical performance.

Part Context

This part belongs to the AMPMODU Mod II family, a widely recognized line of rectangular connectors known for reliability. The series offers various position counts and configurations to support diverse interconnection needs across multiple industries. The 7-146259-4 specifically addresses the need for a 48-pin solution within this established ecosystem.

Replacement Considerations

Direct substitutes include other 48-position, 2.54mm pitch headers from the same manufacturer. Verify pin count, row configuration, and termination method compatibility before swapping. Alternative brands may require re-evaluation of mechanical fit and electrical ratings.
