Overview
The Harwin M20-7870446 is a surface-mount socket assembly featuring eight positions arranged in a dual in-line configuration. It utilizes a 2.54 mm pitch and employs tin-plated contacts for reliable signal transmission. Designed for bottom entry, this component supports vertical PCB mounting via solder termination. The housing material ensures durability under standard reflow conditions, making it suitable for high-density board-to-board interconnections.
Feature Summary
- Dual in-line surface-mount socket design for compact board integration
- Tin-plated contacts ensure corrosion resistance and stable electrical performance
- Bottom entry orientation facilitates efficient PCB layout and routing
Applications
- Board-to-board interconnections
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the current lifecycle status before procurement as availability may be limited. Confirm that the specified tin plating and surface-mount package align with your manufacturing process requirements. Ensure compatibility with standard reflow soldering profiles to maintain connector integrity during assembly.
Selection Notes
Select this component when a low-profile, dual-row female header is required for surface-mount applications. The 2.54 mm pitch matches standard industrial spacing, while the tin finish offers a cost-effective solution for general-purpose signaling. Consider the bottom-entry orientation for optimal board space utilization.
Part Context
This part belongs to the Harwin M20 series, which provides robust rectangular connectors for demanding environments. The series is characterized by its durable construction and compliance with industry standards. This specific model represents a compact solution within the broader family of headers and wire housings designed for reliable electronic interconnects.
Replacement Considerations
Direct substitutes are not explicitly confirmed in available documentation. Verify mechanical dimensions and pinout compatibility if considering alternative manufacturers. Ensure any replacement maintains the same 2.54 mm pitch and surface-mount footprint to fit existing PCB layouts.
