Frequently Asked Questions
How many positions does the M20-9720845 provide, and what pin pitch does it use for board compatibility?
The M20-9720845 is a 16-position connector arranged in a dual-in-line (8+8) configuration with a standard 2.54 mm (0.1-inch) pitch. This pitch is compatible with breadboards, DIP sockets, and a wide range of development boards, making it easy to interface with Arduino, Raspberry Pi, or custom microcontroller PCBs that use standard 2.54 mm header spacing.
For a development board using M20-9720845, how does the 7 mm pin length affect soldering process selection?
The 7 mm pin length of the M20-9720845 allows through-hole pins to protrude sufficiently below PCBs with standard thicknesses of 1.6 mm to 2.0 mm, leaving approximately 4 mm to 5 mm of pin for reliable solder fillet formation. This extra pin length accommodates both automated wave soldering and hand soldering with a standard iron at 350°C, while also enabling use with 0.1-inch pitch wire wrap and machine-pin socket combinations.
When is the M20-9720845 a better choice than a surface-mount connector of similar 16-pin count for a prototype design?
Through-hole connectors like M20-9720845 provide superior mechanical strength and pull-out resistance compared to surface-mount alternatives, with through-hole solder joints capable of withstanding forces greater than 10 N perpendicular to the board. For prototype boards subjected to repeated plug/unplug cycles or connectors used with cables that exert physical stress, the through-hole mounting of M20-9720845 prevents pad lifting failures that SMD connectors are susceptible to in hand-assembly environments.
