Overview
The M20-7860842P is a surface mount socket connector from the Harwin M20 series. It features an 8-position, single-row configuration with a 2.54 mm (0.100 inch) pitch. The component utilizes a bottom-entry design for mating and employs SMT termination for PCB attachment. Contact plating includes gold on the mating interface and tin on the tail, fabricated from phosphor bronze. The housing is constructed from black polyamide (PA6T), rated UL94 V-0, supporting operation between -55°C and +105°C.
Feature Summary
- Surface mount socket assembly with bottom-entry mating orientation
- Gold-plated contacts ensure reliable signal transmission in low-signal applications
- Polyamide insulation provides high thermal stability and flame resistance
- Single-row layout facilitates compact board space utilization
Applications
- High-density electronic assemblies requiring surface mount technology
- Industrial control systems utilizing low-voltage signal interconnects
- Consumer electronics devices with restricted vertical clearance
- Automotive infotainment and sensor modules
Procurement Notes
Verify the specific suffix 'P' indicates the inclusion of positioning pins or polarity features as defined by Harwin documentation. Confirm that the gold/tin contact finish aligns with the intended application's corrosion requirements. Ensure the surface mount footprint matches the manufacturer's recommended land pattern to guarantee solder joint integrity during reflow processes.
Selection Notes
Select this component when a low-profile, surface-mount socket is required for single-row interconnections. The 2.54 mm pitch offers compatibility with standard header systems. Consider the gold-plated mating contacts for superior conductivity in sensitive signal paths compared to tin-only alternatives. Evaluate the -55°C to +105°C temperature range against environmental operating conditions.
Part Context
This part belongs to the M20 family of connectors, known for their robust mechanical design and versatile mounting options. The M20 series supports both through-hole and surface mount configurations across various pin counts. The M20-7860842P specifically addresses needs for compact, reliable socket connections in modern printed circuit board designs where space efficiency is critical.
FAQ
What is the contact material used in this connector?
The contacts are made from phosphor bronze, providing good elasticity and conductivity.
