M20-7870842R

Overview

The M20-7870842R is a surface-mount socket assembly from the Harwin M20 series, designed for board-to-board and wire-to-board connections. It features a dual in-line configuration with 16 positions (8+8) arranged in two rows. The connector utilizes a 2.54 mm pitch and employs a bottom entry interface for mating. Contact plating is gold to ensure reliable conductivity, while the termination method is soldering for PCB integration.

Feature Summary

• Dual in-line socket assembly design
• Surface mount termination style
• Gold contact plating for durability
• Bottom entry mating interface

Applications

• Board-to-board interconnects
• Wire-to-board connections
• General electronic assemblies

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence risks associated with older M20 series variants. Confirm RoHS compliance status via official datasheets before procurement. Ensure storage conditions meet manufacturer specifications to preserve contact integrity. Validate pin count and orientation against schematic requirements prior to ordering.

Selection Notes

Select this component when a low-profile, dual-row surface-mount solution is required. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the bottom entry feature for specific mechanical constraints. Verify that the gold plating meets the environmental exposure requirements of the target application.

Part Context

This part belongs to the M20 series, a family of high-reliability connectors known for their robust construction and precise engineering. The series supports various configurations including single and dual rows with different entry types. The M20-7870842R specifically addresses needs for compact, high-density surface-mount applications requiring durable contacts.

Replacement Considerations

Check for direct substitutes within the M20 series such as M20-7870842 if reel packaging is not strictly required. Evaluate alternative manufacturers offering similar 2.54 mm dual-row SMT sockets only after verifying mechanical footprint and electrical compatibility.
