Overview
The M20-7880446 is a Harwin M20 series dual in-line (DIL) socket assembly featuring eight positions arranged in two rows. It utilizes a 2.54 mm pitch and employs horizontal right-angle through-hole mounting for secure board integration. The connector system supports board-to-board applications with gold-plated contacts rated for 3A current and 1000V voltage. Constructed with polyamide insulation, it operates within a temperature range of -40°C to +105°C.
Feature Summary
- Horizontal right-angle orientation facilitates compact vertical stacking and space-constrained PCB layouts.
- Gold-plated contact surfaces ensure reliable signal transmission and corrosion resistance over extended service life.
- Polyamide insulation material provides high thermal stability and mechanical strength under industrial conditions.
Applications
- General purpose electronic interconnections
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the specific contact plating configuration against project requirements, as datasheets may list variations such as gold-tin combinations. Confirm that the horizontal mounting style aligns with the mechanical constraints of the target enclosure. Ensure the polyamide housing meets the thermal environment specifications for the intended operational lifespan.
Selection Notes
Select this component when a low-profile, right-angle female connector is required for dense circuit board arrangements. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the 1000V rating for applications requiring higher isolation voltages compared to standard 250V connectors.
Part Context
This part belongs to the M20 series, a widely used line of headers and wire housings designed for robust performance. The series offers various configurations including single and double rows with different mounting angles. The M20-7880446 specifically addresses needs for horizontal female receptacles with durable metallic contacts.
Replacement Considerations
Direct substitutes within the same series include M20-7880442, which shares identical physical dimensions and pin count but differs in contact plating specifications. Verify electrical ratings and material compatibility before swapping components to ensure system integrity.
