Key Features
- 46-position 23+23 DIL straight plug in 2.54 mm pitch for standard through-hole dual-row PCB mounting
- 6.1 mm pin length with brass-core tin-over-nickel (Sn/Ni) contacts for reliable solder joint formation and corrosion resistance
- M20 series standard 3 mm body height for compatibility with standard 2.54 mm grid breadboards and IDC cable headers
- Pb-free RoHS compliant construction with male contact gender for mating with standard female DIP socket or IDC connectors
Applications
M20-9982346 is used to connect 46-pin ribbon cables and IDC harnesses to PCBs in embedded system development boards, industrial SBC carriers, and backplane inter-board wiring where 2.54 mm pitch through-hole connectors are required. Its 23+23 DIL straight configuration also makes it compatible with DIP-46 sockets used in EPROM programmers, logic analyzers, and prototype daughter card connectors.

Frequently Asked Questions
How many positions does M20-9982346 provide and in what physical arrangement?
M20-9982346 provides 46 positions in a dual-in-line (DIL) arrangement of 23 pins per row, with a 2.54 mm pitch between contacts. The straight through-hole pin layout spans approximately 57.15 mm in row length, suitable for standard 0.100 inch grid PCBs and IDC ribbon cable mating.
What is the pin length of M20-9982346 and how does it affect soldering on standard PCBs?
M20-9982346 has 6.1 mm pin length, which provides approximately 2.5 mm to 3 mm of pin protrusion below a standard 1.6 mm PCB. This protrusion length is within the recommended range for wave soldering and hand soldering, ensuring good solder joint wetting without excessive trimming.
Which industrial or embedded development boards commonly use a 46-position DIL THT connector like M20-9982346?
Raspberry Pi expansion boards, Arduino Mega shields, industrial SBC I/O headers, and custom backplane connectors use 46-position 2.54 mm DIL connectors. M20-9982346 fits standard 46-pin IDC ribbon cable assemblies and DIP-46 breakout sockets, covering GPIO, address bus, and data bus interfaces on embedded systems with 23 or more I/O lines per row.
What contact material and finish does M20-9982346 use and how does this compare to gold-plated alternatives?
M20-9982346 uses brass contacts with tin (Sn) mating finish over a nickel (Ni) barrier. Tin-plated contacts provide reliable electrical connection at contact resistance below 30 mΩ for applications with fewer than 50 mating cycles, at lower cost than gold-plated alternatives which are typically required for 500+ cycle high-reliability connectors.
