M20-7831342

Overview

The M20-7831342 is a rectangular connector receptacle from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 26 positions with a 0.100 inch (2.54 mm) pitch arranged in two rows. The connector utilizes through-hole mounting and gold-plated phosphor bronze contacts housed in black polyamide insulation rated UL94 V-0. It supports a current rating of 3A and a voltage rating of 1000V, operating within a temperature range of -40°C to +105°C.

Feature Summary

• Push-pull latching mechanism ensures secure mating and unmating.
• Gold-plated square contacts provide reliable electrical performance.
• Polyamide housing offers high thermal stability and flame resistance.

Applications

• Industrial control systems
• Telecommunications equipment
• General electronic assemblies

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm that the specific ordering suffix matches the required contact plating and termination style. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate that the part number corresponds to the exact pin count and row configuration required for the design.

Selection Notes

Select this component when a robust push-pull latching system is required for high-reliability connections. Consider the 1000V rating and 3A current capacity for power distribution needs. Verify that the 2.54mm pitch aligns with existing PCB footprint constraints. Evaluate the through-hole termination method against available assembly processes.

Part Context

This receptacle belongs to the M20 series, which is characterized by its durable push-pull locking feature. The series is widely used in demanding environments requiring secure mechanical retention. The M20-7831342 specifically provides a 26-position interface suitable for dense board-to-board interconnections.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin M20 series variants only if pin count and latching mechanism requirements can be adjusted.
