Overview
The M80-8273442 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a vertical surface mount design with 34 positions arranged in a dual inline (17+17) configuration. The component utilizes a 2.00mm pitch and includes friction latch locking for secure mating. Contact materials are phosphor bronze with tin plating, housed in black polyphenylene sulfide (PPS). Rated current is 2.2A per contact at 120V, operating within -55°C to 125°C.
Feature Summary
- Vertical surface mount topology for direct PCB integration
- Dual inline structure with friction latch retention mechanism
- Tin-plated phosphor bronze contacts for reliable conductivity
- High-temperature resistant PPS insulation material
Applications
- Industrial control system interconnects
- Automotive electronic module connections
- Telecommunications equipment backplanes
- Medical device internal circuitry
Procurement Notes
Verify the specific suffix '442' against the latest Harwin datasheet to confirm tin plating and latch type. Check RoHS compliance status as manufacturing processes may evolve. Confirm availability through authorized distributors since this series may have lifecycle variations. Ensure EDA models match the exact physical dimensions for accurate PCB footprint placement.
Selection Notes
Select this part when vertical SMT space is constrained but high pin counts are required. The friction latch eliminates need for separate screws, simplifying assembly. Compare against M80-826 series if lead-free requirements differ or if alternative latching mechanisms are preferred. Validate thermal resistance during soldering against the PGS material limits.
Part Context
This component belongs to the Datamate L-Tek family, known for robust industrial connectivity. It complements socket counterparts like M80-820 series. The 34-position variant serves applications needing dense I/O without increasing board area significantly compared to single-row solutions.
Replacement Considerations
M80-8273442P is a potential alternative offering similar form factor with different plating options. Verify mechanical compatibility of the friction latch interface before substitution.
