Overview
The M20-7880246 is a rectangular connector socket assembly from the Harwin M20 series. It features a dual in-line (DIL) configuration with 4 positions arranged in 2 rows. The component utilizes a 2.54 mm (0.1 inch) pitch and is designed for through-hole mounting with a right-angle orientation. The contacts are female sockets terminated with tin plating, suitable for board-to-board applications.
Feature Summary
- Dual in-line socket assembly design for compact board-to-board interconnects
- Right-angle through-hole termination for specific PCB layout requirements
- Tin-plated female contacts ensuring reliable electrical connection
Applications
- Board-to-board interconnection systems
- Industrial control circuitry
- Consumer electronic device assemblies
Procurement Notes
Verify the current lifecycle status of the M20-7880246 before procurement planning, as availability may be limited. Confirm that the right-angle through-hole form factor aligns with the target PCB footprint and mechanical constraints. Ensure compatibility with mating pin headers within the same M20 series to maintain interface integrity.
Selection Notes
Select this component when a low-profile, right-angle DIL socket is required for 2-row connections. The 2.54 mm pitch ensures compatibility with standard industrial header systems. Consider the tin contact finish for general-purpose applications where gold plating is not strictly necessary for corrosion resistance or signal integrity.
Part Context
This part belongs to the Harwin M20 series, which provides industrial-standard connectors for high-density PCB applications. The series offers various configurations including vertical and horizontal orientations with different row counts and contact finishes to suit diverse mechanical and electrical design needs.
Replacement Considerations
Compatible substitutes include other M20 series sockets with matching 2.54 mm pitch and 4-position DIL layout. Verify that alternative parts maintain the same right-angle through-hole mounting style and tin contact specifications to ensure mechanical and electrical interchangeability.
