Overview
The M20-7873742 is a dual-in-line (DIL) socket assembly manufactured by Harwin Inc. within the M20 series. It features a 14-position configuration arranged in two rows, providing a total of 14 contact points for reliable electrical interconnection. The component utilizes a 2.54 mm (0.1 inch) pitch to ensure compatibility with standard board layouts. Designed for surface mount technology (SMT), it employs a solder termination type for secure PCB attachment. The connector supports both bottom and top entry configurations, offering flexibility in mating orientation. Contact surfaces are finished with gold plating to enhance conductivity and corrosion resistance.
Feature Summary
- Dual-row DIL socket assembly designed for surface mount applications
- Supports flexible bottom or top entry mating orientations
- Gold-plated contacts ensure reliable signal transmission
Applications
- Board-to-board interconnections
- Cable-to-board connections
- General electronic equipment
Procurement Notes
Verify current availability status as this component may be subject to obsolescence notices. Confirm that the specific ordering suffix matches the required entry style and termination type. Ensure compliance with RoHS directives if applicable to your manufacturing process. Cross-reference the datasheet for precise mechanical dimensions before finalizing procurement decisions.
Selection Notes
Select this model when a 14-position SMT socket with dual-row layout is required. Consider the 2.54 mm pitch for standard spacing requirements. Evaluate the need for bottom versus top entry based on assembly constraints. Verify that the gold contact finish meets the environmental durability needs of the target application.
Part Context
This part belongs to the Harwin M20 series, a range of connectors known for their robust design and versatility. The M20 series offers various configurations including headers, sockets, and wire housings. This specific socket assembly is engineered for high-density applications requiring reliable surface mount connectivity.
Replacement Considerations
Check for direct substitutes within the M20 series that offer identical pin counts and pitch. Verify compatibility with existing PCB footprints and mating components before transitioning to alternative part numbers.
