Overview
The Harwin M80-7820442 is a vertical board header from the Datamate L-Tek series, featuring four positions with a 2.00mm pitch. It utilizes male pins for board-to-board or cable connections, designed for through-hole mounting and solder termination. The connector supports a rated current of 2.2A and a voltage rating of 120V, operating within a temperature range of -55°C to 125°C. Insulation is provided by black polyamide (PA46) material meeting UL94 V-0 flammability standards. Contact finishes include gold plating on mating surfaces and tin-lead on tails.
Feature Summary
- Vertical orientation design facilitates direct board-to-board integration
- Four-wall shielding provides electromagnetic interference protection
- Latch bracket system ensures secure mechanical retention
Applications
- Compact electronic device interconnects
- Board-to-board signal transmission
- Cable assembly connections
Procurement Notes
Verify component authenticity against official Harwin documentation due to discontinued status. Confirm RoHS compliance requirements as this specific part may not meet current environmental directives. Validate pin count and stacking height compatibility with mating connectors before procurement. Ensure storage conditions maintain moisture sensitivity level integrity.
Selection Notes
Select this component when vertical mounting space is constrained and shielding is required. Verify that the 2.00mm pitch matches the target circuit layout. Check if the 2.2A current rating suffices for the application load. Consider alternative models if lead-free soldering processes are mandatory due to tin-lead tail finish.
Part Context
This connector belongs to the Datamate L-Tek family, known for high-reliability applications in harsh environments. The series offers various configurations including different stacking heights and contact materials. This specific model represents a standard vertical header variant within the broader product ecosystem.
Replacement Considerations
M80-7520422 is listed as an obsolete predecessor. M80-7820445 is a verified substitute with identical positioning and electrical characteristics but potentially different contact finishes.
