What are the key features of M20-7823642?

  • 36-position female socket connector on 0.1-inch (2.54 mm) pitch for standard 0.1-inch header mating
  • Gold contact finish on mating surfaces for low-resistance, corrosion-resistant connections in demanding environments
  • Tin over nickel termination finish optimized for reliable PCB soldering and long-term contact integrity
  • Straight through-hole PTH box design (3.6 inch body length) for secure board mounting with high mechanical retention
  • RoHS-compliant lead-free construction for global regulatory acceptance

What is M20-7823642 used for?

The M20-7823642 is used in prototyping boards, development kits, and embedded system backplanes where a reliable 36-position, 0.1-inch pitch female receptacle is needed for module interconnection. Its gold-plated contacts ensure low contact resistance in signal and power distribution applications across industrial automation, test equipment, and computing peripherals. The straight PTH box style provides strong mechanical retention suitable for applications subject to vibration or repeated mating cycles.

Frequently Asked Questions

What mating connector pitch does the M20-7823642 require, and which standard header series is compatible?

The M20-7823642 uses the industry-standard 0.1-inch (2.54 mm) pitch, making it directly compatible with Harwin M20 series straight male headers and the vast majority of 0.1-inch pin headers from other manufacturers. The 36-position configuration mates with corresponding 36-pin male headers in a single row arrangement. This ubiquitous pitch ensures wide cross-vendor compatibility for prototyping, development boards, and industrial control backplanes.

Why does the M20-7823642 use gold on the mating contacts and tin-over-nickel on the termination contacts?

Gold plating on the 36 mating contacts provides stable, low-resistance connections by resisting oxidation over thousands of insertion and removal cycles, ensuring signal integrity in high-reliability applications. Tin over nickel on the PCB termination tails improves solder wettability during reflow or wave soldering, creating strong mechanical and electrical bonds to the board. This dual-finish strategy is a standard industry practice balancing cost, reliability, and manufacturing compatibility across a 3.6-inch body length connector.

In what vibration-intensive applications is the through-hole PTH design of the M20-7823642 preferable to SMT alternatives?

The straight PTH box mounting of the M20-7823642 anchors the 36-position connector body mechanically through the PCB, providing significantly higher pull-out and lateral force resistance than SMT receptacles. This makes it preferable in industrial automation equipment, motor control panels, railway electronics, and test instrumentation where boards are subject to continuous vibration at frequencies from a few Hz up to several hundred Hz. The 0.335-inch body depth and 3.6-inch length distribute mechanical stress over a large soldering area, reducing the risk of pad lift under shock loads.
