Overview
The M20-7910242R is a 2-position surface mount board-to-board receptacle connector from the Harwin M20 series. It features a 2.54 mm (0.100 inch) pitch and is designed for right-angle horizontal mounting on printed circuit boards. The contacts are gold-plated with a tin post finish to ensure reliable signal transmission. The housing utilizes polyamide (PA9T), also known as Nylon 9T, reinforced with glass for enhanced thermal stability and mechanical strength. This component supports a current rating of 3A and provides an insulation resistance of 1 GOhm.
Feature Summary
- Surface mount design for automated assembly processes
- Gold-plated contacts for low contact resistance
- Glass-reinforced polyamide insulation for durability
Applications
- General purpose board-to-board interconnections
- Compact electronic device assemblies
- Industrial control modules
Procurement Notes
Verify that the specific suffix 'R' corresponds to the tape and reel packaging format required for your pick-and-place equipment. Confirm that the 2.54 mm pitch matches the target footprint layout. Ensure the right-angle orientation aligns with the mechanical constraints of the final enclosure design before initiating production orders.
Selection Notes
Select this part when a low-profile, right-angle connection is necessary for space-constrained applications. The 3A current rating suits moderate power signals. Consider the PA9T material if higher heat resistance is needed compared to standard nylon variants. Verify compatibility with mating header pins from the same M20 series family.
Part Context
This component belongs to the M20 series of connectors, which are characterized by their compact size and high-density capabilities. The series offers various configurations including headers and receptacles in different pin counts. The M20-7910242R specifically addresses the need for a small-footprint, two-channel interface solution in modern electronics manufacturing.
Replacement Considerations
Compatible substitutes include other 2-pin, 2.54mm pitch SMT receptacles from manufacturers such as Samtec or Molex. Ensure the replacement maintains the same right-angle profile and housing height to fit existing PCB layouts without mechanical interference.
