Overview
The Oupiin 4976-2X10TSB is a wire-to-board connector header designed for through-hole mounting. It features a dual-row configuration with 20 positions, providing a total of 20 male pins. The connector utilizes a 3.00mm (0.118 inch) pitch between contacts. The housing is constructed from plastic material rated UL 94V-0 for flame resistance and is available in white color. This component supports wire gauges ranging from 30 AWG to 18 AWG and carries a current rating of up to 10.3 Amperes.
Feature Summary
- Dual-row header design with kinked leads for secure PCB retention
- UL 94V-0 rated plastic housing for enhanced fire safety
- Locking feature ensures reliable mating connection stability
Applications
- Industrial control systems requiring robust power connections
- Consumer electronics utilizing 3.0mm pitch wiring harnesses
- General-purpose board-to-wire interconnects
Procurement Notes
Verify the specific pin count and row configuration against the datasheet to ensure compatibility with the target PCB footprint. Confirm that the housing material meets the required environmental and thermal standards for the intended application environment. Ensure the selected wire gauge falls within the supported range of 18 AWG to 30 AWG for optimal contact performance.
Selection Notes
Select this component when a dual-row 3.00mm pitch header is required for through-hole assembly. Consider the 10.3A current capacity and UL 94V-0 rating if higher thermal or electrical performance is needed compared to standard 2.54mm connectors. Evaluate the kinked lead design for applications requiring enhanced mechanical stability during soldering.
Part Context
This part belongs to the Oupiin 4976 series, which specializes in 3.00mm pitch wire-to-board connectors. The series offers various configurations including single and dual rows, with options for surface mount or through-hole termination. The 4976 series is characterized by its locking mechanisms and support for a wide range of wire gauges, making it suitable for diverse electronic assemblies.
Replacement Considerations
Direct substitutes may include other 3.00mm pitch dual-row headers from different manufacturers, provided they match the 20-position count, through-hole termination style, and compatible current ratings. Verify mechanical dimensions and pin spacing to ensure interchangeability without PCB redesign.
