Overview
The M20-7920442R is a 8-position receptacle connector from the Harwin M20 series, designed for surface mount right-angle board-to-board applications. It features a 0.100 inch (2.54mm) pitch and utilizes gold-plated phosphor bronze contacts with a 3A current rating. The housing is constructed from black PA9T nylon with UL94 V-0 flammability, supporting an operating temperature range of -40°C to 105°C.
Feature Summary
- Right-angle surface mount design for compact PCB integration
- Gold-plated phosphor bronze contacts ensure reliable signal transmission
- High-temperature resistant PA9T insulation material
Applications
- Board-to-board interconnections
- Wire-to-board connections
- General electronic equipment
Procurement Notes
Verify the specific suffix 'R' against official datasheets to confirm RoHS compliance status. Ensure compatibility with mating header part numbers within the same M20 series family. Confirm that the right-angle surface mount footprint matches the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, right-angle connection is required for dense board stacking. The 2.54mm pitch offers standard spacing compatibility. Consider the 3A current rating and 500V voltage capability for circuit requirements. Verify that the surface mount termination method aligns with the assembly process capabilities.
Part Context
This part belongs to the Harwin M20 series, which provides a comprehensive range of headers and wire housings. The series is characterized by its versatile mounting options and robust construction, suitable for various industrial and commercial electronic applications requiring reliable interconnect solutions.
Replacement Considerations
Compatible mating parts include other M20 series headers such as M20-9990846. Ensure the replacement maintains the same 2.54mm pitch, 8-position count, and right-angle orientation to guarantee mechanical and electrical compatibility.
