Overview
The M20-7883942 is a dual in-line (DIL) socket assembly manufactured by Harwin Inc. within the M20 series. It features a 39+39 position configuration, totaling 78 contacts arranged in two rows. The connector utilizes a 2.54 mm pitch and is designed for horizontal surface mount technology (SMT) termination. Electrical specifications include a current rating of 3 A and a voltage rating of 1000 V. The housing material is polyamide (PA6T/Nylon 6T), providing thermal stability. Contact plating consists of gold over tin to ensure reliable signal transmission.
Feature Summary
- Dual row DIL socket design for high-density board-to-board or wire-to-board connections
- Horizontal surface mount termination for automated PCB assembly processes
- Gold and tin contact plating for enhanced conductivity and corrosion resistance
- Polyamide insulation material supporting industrial and telecommunications environments
Applications
- General purpose electronic interconnections
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the specific lifecycle status with the manufacturer, as product availability may vary. Confirm that the horizontal SMT orientation matches the PCB layout requirements. Ensure compatibility with mating pin headers from the same M20 series family. Check RoHS compliance documentation for regulatory adherence in target markets.
Selection Notes
Select this component when a high-count, low-profile horizontal connection is required. The 2.54 mm pitch ensures compatibility with standard industry spacing. Consider the 1000 V rating for applications requiring higher isolation. Verify that the 3 A current capacity meets the circuit load requirements without overheating.
Part Context
This part belongs to the Harwin M20 series, which offers a range of header and wire housing solutions. The M20 series is characterized by its robust construction and suitability for harsh environments. This specific model represents a high-pin-count variant optimized for surface mount integration.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Consult Harwin directly for obsolescence management or equivalent alternatives.
