Overview
The M20-7872942 is a dual-row socket header from the Harwin M20 series, designed for surface-mount board-to-board applications. It features 40 positions with a 2.54 mm (0.100 inch) pitch and utilizes square female contacts. The connector employs a push-pull latching mechanism to ensure secure mating. Contacts are gold-plated for reliable signal transmission, while the tail is tin-plated for solderability. Constructed with black polyamide insulation rated UL94 V-0, it supports a maximum current of 3A per contact at 250V. The operating temperature range spans from -40°C to +105°C.
Feature Summary
- Push-pull latching system for secure mechanical retention
- Gold-plated square female contacts for durability
- Surface-mount termination for automated assembly
Applications
- Board-to-board interconnections in industrial equipment
- Signal routing in medical electronic devices
- Data handling systems in metering and measurement instruments
Procurement Notes
Verify the specific suffix against the official datasheet to confirm pin count and plating specifications. Ensure compatibility with mating headers regarding stacking height and latching force. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when a robust, high-density connection is required for surface-mounted assemblies. The dual-row configuration maximizes I/O density within a limited footprint. Evaluate thermal requirements against the 105°C limit and ensure PCB layout accommodates the specified stacking heights for proper engagement.
Part Context
This part belongs to the M20 series, which provides versatile interconnect solutions for harsh environments. The series offers various row counts and mounting styles, including SMT and through-hole options. The M20-7872942 specifically addresses needs for high-reliability connections in compact electronic designs requiring secure latching.
Replacement Considerations
Consult the official Harwin replacement guide for verified substitutes. Cross-reference mating connectors to ensure mechanical and electrical compatibility. Verify that alternative parts meet identical stacking height and latching force requirements.
