M80-7404542

Overview

The Harwin M80-7404542 is a Datamate J-Tek male header connector featuring 45 positions arranged in a 3-row configuration. It utilizes a 2.00mm (0.079 inch) pitch and is designed for right-angle surface mount installation with solder termination. The contacts are constructed from phosphor bronze with gold plating, housed in a black polyamide casing. Rated for 3A current and 360V voltage, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• High-density 45-position interconnect solution in a compact 3-row layout
• Right-angle surface mount design facilitates space-constrained PCB integration
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Polyamide housing provides thermal stability up to 125°C

Applications

• Board-to-board interconnects in high-pin-count assemblies
• Cable-to-board connections requiring right-angle routing
• Industrial control systems with dense I/O requirements
• Automotive electronics modules needing robust connectivity

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm pin count, row configuration, and mounting style. Ensure compatibility with standard SMT reflow profiles. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm that the gold plating thickness meets application requirements for contact resistance.

Selection Notes

Select this component when a high-density, right-angle header is required for board-to-board or cable applications. The 3-row format maximizes pin density within a limited footprint. Verify that the 2.00mm pitch aligns with mating connector specifications. Consider the 360V rating and 3A current capacity for electrical load requirements. Ensure the surface mount package fits within the available PCB area and clearance constraints.

Part Context

This connector belongs to the Harwin Datamate J-Tek series, known for its push-pull locking mechanism and high reliability. The M80-7404542 variant specifically addresses needs for high-pin-count interconnects in compact spaces. It complements other Datamate products by offering a specialized right-angle surface mount option for complex system architectures.

Replacement Considerations

Compatible substitutes include other Datamate J-Tek headers with matching 45-position, 3-row, right-angle SMT configurations. Verify identical 2.00mm pitch, gold-plated phosphor bronze contacts, and polyamide housing material. Ensure mating connectors share the same locking mechanism and dimensional tolerances.
