What are the key features of M20-9980745?
- 14-position dual in-line (7+7) configuration on 2.54mm pitch fits standard 0.100" footprint for broad compatibility with sockets and female headers
- 6.1mm pin length with 3mm through-hole termination depth provides secure mechanical retention and reliable solder joint in THT wave or hand soldering
- Gold (Au) over Nickel (Ni) termination finish on brass contacts ensures low contact resistance and strong solderability across the full operating temperature range
- Straight plug orientation suits vertical board-to-board stacking and wire-to-board harness assembly with standard 2.54mm pitch crimp sockets
- RoHS-compliant (Pb-free) materials support green electronics manufacturing and compliance with global environmental regulations
What is M20-9980745 used for?
The M20-9980745 is widely used in embedded system development boards, test and measurement fixtures, and industrial control PCBs where a robust 14-pin dual in-line through-hole connector is needed for reliable board-to-wire or board-to-board mating. Its 2.54mm pitch is compatible with the vast majority of standard socket housings, IDC cable assemblies, and breadboard strips, making it a versatile choice for prototype bring-up and low-to-medium volume production. The gold-plated brass contacts and 6.1mm pin length also make it suitable for edge-mount adapter boards and programming jigs in electronics manufacturing test environments.

Frequently Asked Questions
How does the 6.1mm pin length of M20-9980745 affect PCB stackup and clearance in dual-board assemblies?
The 6.1mm pin length on the M20-9980745, combined with the 3mm through-hole termination depth, leaves approximately 3.1mm of pin exposed above the PCB surface after soldering. When mated with a standard 2.54mm pitch female socket of 8.5mm total height, the resulting board-to-board standoff is approximately 8mm to 10mm, providing adequate clearance for components up to 6mm tall on the lower board. This is a common stackup dimension in Arduino-shield and Raspberry Pi HAT style module designs.
What mating sockets are compatible with the M20-9980745, and what current rating should designers expect per contact?
The M20-9980745 is mechanically and electrically compatible with Harwin M20-series 14-pin dual in-line female sockets (such as M20-7820745) and most standard 2.54mm pitch dual-row female headers from other manufacturers. Each contact is rated for approximately 1A continuous current at 25°C ambient, with the brass-and-gold contact system maintaining contact resistance below 20mΩ over hundreds of mating cycles, suitable for signal and low-power supply connections up to 14W total per connector.
When should a designer use the M20-9980745 over a 2mm pitch alternative for a 14-pin interconnect?
The M20-9980745 at 2.54mm (0.100") pitch is preferred when board space is not the limiting constraint and lowest-cost mating cable assemblies are required, since 2.54mm pitch IDC ribbon cable, crimp sockets, and test clips are available from dozens of suppliers at commodity pricing. A 2mm pitch alternative saves roughly 30% linear board space on the connector row but requires more expensive tooling and cables. The 2.54mm pitch is also the dominant choice for hand-soldering in prototyping and repair scenarios, as the larger pin-to-pin clearance of 2.54mm versus 2.0mm reduces solder bridge risk.
How many mating cycles is the M20-9980745 designed to withstand, and how does this influence test fixture design?
Harwin M20-series connectors are rated for a minimum of 500 mating cycles with gold-plated contacts maintaining contact resistance below 30mΩ throughout their rated life. In a production test fixture where a board under test is inserted and removed 50 times per day, the M20-9980745 would remain within specification for approximately 10 days of continuous use before contact wear may degrade signal integrity. For higher-cycle fixtures (more than 10,000 cycles), Harwin's Gecko or M80 series with reinforced contact spring designs are recommended over the M20 series.
