Frequently Asked Questions
How many positions and what pitch does the M20-7870442 connector provide?
The M20-7870442 is an 8-pin (4+4 dual-in-line) SMT receptacle with a 2.00mm pitch between adjacent contacts. The connector stands 7.5mm high after board mounting, providing clearance for mating headers on daughter cards or piggyback PCBs in stacked board-to-board assemblies.
What contact plating does the M20-7870442 use and how does it affect long-term reliability?
The M20-7870442 uses a gold plus tin hybrid contact finish: gold on the mating interface for low contact resistance and reliable electrical connection over repeated insertions, and tin-over-nickel barrier plating on the SMT termination side for excellent solderability and corrosion resistance across the component's service life.
Can the M20-7870442 be assembled by standard automated SMT pick-and-place equipment?
Yes. The M20-7870442 is a surface mount component with a standardized 2.00mm pitch and regular rectangular body measuring approximately 10.4mm × 7.5mm, compatible with automated pick-and-place feeders and reflow soldering at standard lead-free solder paste profiles, typically 260°C peak, minimizing manual assembly cost in volume production.
In which application sectors is the Harwin M20-7870442 commonly specified?
The M20-7870442 is commonly specified in industrial automation, robotics controllers, scientific instruments, and embedded computing systems where a 2.00mm pitch SMT DIL socket must connect a processor board to a peripheral or sensor daughter card. Its RoHS compliance and Harwin's M20-series ecosystem of compatible headers also make it popular in aerospace ground-support electronics where board-swap modularity and 8-pin connector standardization are valued.
