M20-7882142

Overview

The M20-7882142 is a rectangular connector receptacle from the Harwin M20 series, designed for through-hole mounting with right-angle termination. It features 42 positions arranged in a dual-row configuration with a 0.100 inch (2.54 mm) pitch. The contacts are made of phosphor bronze with gold plating to ensure reliable signal transmission. The housing is constructed from black polyamide (PA6T), offering UL94 V-0 flammability rating and an operating temperature range of -40°C to +105°C. Rated at 3A per contact and 250V, this board-to-board or cable connector utilizes a push-pull locking mechanism for secure mating.

Feature Summary

• Right-angle through-hole termination facilitates compact PCB layout integration
• Gold-plated phosphor bronze contacts provide durable conductivity and corrosion resistance
• Push-pull locking system ensures secure mechanical retention during operation

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment interfaces
• General-purpose electronic assemblies needing high-density connections

Procurement Notes

Verify the specific suffix against the official datasheet to confirm right-angle orientation and pin count. Ensure compatibility with mating header specifications regarding stacking height and contact length. Confirm RoHS compliance status if required by project standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when right-angle through-hole mounting is necessary for space-constrained designs. The dual-row configuration supports higher density compared to single-row alternatives. Verify that the 2.54mm pitch matches the target PCB footprint. Consider the push-pull locking requirement for vibration-prone environments where standard latches may be insufficient.

Part Context

This part belongs to the Harwin M20 series, a family of high-performance connectors known for reliability in harsh environments. The series offers various configurations including surface mount and through-hole options. The M20-7882142 specifically addresses applications requiring right-angle connectivity with secure locking mechanisms.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 42-position count, 2.54mm pitch, right-angle through-hole termination, and push-pull locking mechanism.
