Overview
The Harwin M20-7871446P is a board connector featuring 28 contacts arranged in a dual inline (DIL) configuration with two rows. It utilizes a 0.1 inch (2.54 mm) pitch and employs surface mount terminals for PCB attachment. The component includes a locking mechanism and uses black insulator material. Electrical specifications include a dielectric withstand voltage of 600VAC, a maximum insertion force of 2.0016 N, and an insulation resistance of 1,000,000,000 Ω.
Feature Summary
- Dual row female socket assembly designed for surface mount technology
- Integrated locking mechanism to secure mating connections
- Black insulator housing constructed from durable polymer materials
Applications
- Electronic circuit board interconnections requiring DIL sockets
- Surface mount assembly processes for consumer electronics
- Industrial control systems utilizing standard 2.54mm pitch connectors
Procurement Notes
Verify the specific suffix 'P' against the manufacturer's official datasheet to confirm if it denotes a specific packaging variant or tape-and-reel configuration distinct from the base part number. Ensure compatibility with automated pick-and-place equipment if surface mount assembly is planned. Confirm RoHS compliance status through current regulatory documentation provided by Harwin Inc.
Selection Notes
Select this component when a 28-position dual row female header is required for surface mount applications. The 0.1 inch pitch ensures compatibility with standard pin headers. Consider the integrated locking feature for applications requiring enhanced mechanical stability during vibration. Verify that the 600VAC rating meets the system's electrical isolation requirements.
