Overview
The Harwin M20-7822946 is a 29-position single-row socket assembly from the M20 series, designed for board-to-board connections. It features a 2.54 mm pitch and vertical through-hole termination. The housing is constructed from nylon, while contacts are made of bronze with nickel plating and tin overplating. Rated for 12A current, it operates within a temperature range of -40°C to 105°C and complies with RoHS standards.
Feature Summary
- Vertical single-row configuration optimized for high-density PCB layouts
- Durable double-beam contact design ensures reliable electrical connection
- Compatible with standard SMT reflow processes despite through-hole mounting
Applications
- Industrial control systems requiring robust interconnects
- Consumer electronics with space-constrained designs
- Automotive electronic modules
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm pin count, row configuration, and termination style. Ensure compatibility with mating header specifications regarding current rating and operating temperature range before finalizing procurement orders.
Selection Notes
Select this component when a vertical, single-row interface is required for direct board stacking. The 2.54 mm pitch aligns with industry-standard spacing, facilitating integration with common mating connectors. Verify mechanical height constraints and thermal requirements against the specified -40°C to 105°C operational limits.
Part Context
This part belongs to the Harwin M20 series, a line of industrial standard headers and wire housings. The series is characterized by compact designs suitable for applications with strict density and height limitations, offering versatile options for both surface mount and through-hole implementations.
Replacement Considerations
Consult the official Harwin obsolescence notifications or distributor cross-reference lists for verified substitute part numbers. Do not assume functional equivalence with generic competitors without validating pinout, mechanical dimensions, and electrical ratings.
