M20-7870746

Overview

The Harwin M20-7870746 is a 14-position dual in-line socket assembly designed for surface mount technology. It features a 2.54 mm pitch and a 2-row configuration with bottom entry termination. The contacts are tin-plated to ensure reliable connectivity, while the housing provides structural integrity for PCB integration. This component belongs to the M20 series, which is engineered for high-density board-to-board applications requiring robust mechanical stability and consistent electrical performance in compact electronic systems.

Feature Summary

• Dual row socket assembly with bottom entry design for efficient PCB routing
• Tin-plated contacts provide corrosion resistance and stable signal transmission
• Surface mount termination enables automated placement and secure board attachment
• Compact form factor supports high-density interconnect requirements

Applications

• Board-to-board interconnections in embedded computing systems
• High-density wiring harnesses in industrial control modules
• Signal distribution in communication equipment backplanes
• Interfacing between daughterboards and motherboards in consumer electronics

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence risks. Confirm RoHS compliance status via official datasheets before integration. Check for end-of-life notifications from Harwin Inc. to assess long-term availability. Ensure storage conditions maintain contact plating integrity. Validate pin count and orientation against schematic requirements prior to procurement.

Selection Notes

Evaluate thermal management capabilities during reflow soldering processes to prevent warping. Consider mating connector compatibility regarding contact geometry and retention force. Assess spatial constraints on the PCB layout to accommodate the dual-row profile. Review environmental ratings if the application involves extreme temperatures or humidity. Compare alternative pitches if higher density is required without changing footprint.

Part Context

This component is part of the M20 series by Harwin Inc., a line of connectors known for reliability in demanding environments. The series offers various configurations including single and double rows with different termination styles. The M20-7870746 specifically addresses needs for surface-mounted, low-profile connections where space efficiency and durability are critical factors in modern electronic device manufacturing.

Replacement Considerations

M20-7870742P serves as a gold-plated variant within the same series offering similar physical dimensions but enhanced conductivity properties.
