Overview
The Oupiin 2011-2X20G00SK028B is a board-to-board connector header featuring 40 contacts arranged in two rows. It utilizes a 0.100 inch (2.54mm) pitch and employs male pin terminals for connection. The component supports through-hole solder termination, ensuring secure attachment to printed circuit boards. Designed for reliable signal transmission, it operates within a temperature range of -40°C to 105°C and carries a current rating of 3A.
Feature Summary
- Dual-row configuration providing 40 contact positions
- Male pin terminal design for header applications
- Through-hole solder termination method
- Standard 0.100 inch (2.54mm) contact spacing
Applications
- General-purpose electronic equipment interconnections
- Industrial control system circuit boards
- Consumer electronics internal wiring
- Communication device signal routing
Procurement Notes
Verify the specific suffix 'K028B' against official manufacturer documentation to confirm exact physical dimensions and mating compatibility. Ensure that the through-hole termination style matches your PCB fabrication capabilities. Cross-reference the 3A current rating with your application's thermal requirements to prevent overheating during operation.
Selection Notes
Select this component when a dual-row male header is required for standard 2.54mm pitch layouts. Consider the 3A current capacity and -40°C to 105°C operating range against environmental conditions. Evaluate the through-hole mounting requirement versus surface-mount alternatives if space constraints or automated assembly processes dictate different termination styles.
Part Context
This part belongs to the Oupiin 2011 series, which specializes in 2.54mm pitch male pin headers. The series offers various row configurations and contact counts to suit diverse board-to-board connectivity needs. Oupiin manufactures these connectors using copper alloy materials with gold plating to ensure low contact resistance and durability.
Replacement Considerations
Compatible substitutes include other 2x20 male pin headers with 2.54mm pitch and through-hole termination. Verify that alternative parts match the 3A current rating and -40°C to 105°C temperature specifications. Check mechanical height and width dimensions to ensure fit within the designated PCB footprint.
