Overview
The Oupiin 2111-1X40G00SB is a single-row male board connector featuring 40 contacts with a 2.54mm (0.100 inch) pin pitch. Designed for through-hole solder termination, it utilizes gold-plated copper alloy terminals to ensure reliable conductivity and corrosion resistance. The component supports a current rating of 1A and withstands dielectric voltages up to 500V AC. Its straight orientation and low-profile housing facilitate dense PCB layouts while maintaining secure mechanical connections in various electronic assemblies.
Feature Summary
- Single-row male configuration with 40 pins
- Gold-plated copper alloy contact finish
- Low-profile straight orientation design
- Through-hole solder termination method
Applications
- General-purpose computer motherboards
- Communication equipment signal interfaces
- Industrial control system circuit boards
- Consumer electronics internal wiring
Procurement Notes
Verify the specific suffix designation against official Oupiin documentation to confirm exact plating thickness and material specifications. Ensure compatibility with mating female headers regarding pitch tolerance and housing height. Confirm RoHS compliance status for the specific production batch if required by project regulations.
Selection Notes
Select this component when a single-row 2.54mm pitch header is required for high-density applications. Consider the 1A current rating and 500V dielectric strength for electrical safety margins. Evaluate the low-profile form factor against available vertical clearance on the target printed circuit board assembly.
Part Context
This part belongs to the Oupiin 2111 series of rectangular connectors, which are widely utilized in computing and industrial sectors. The series emphasizes automated manufacturing precision and ISO9001 quality standards. It serves as a standard interconnection solution for signal transmission between rigid PCBs and external modules or cables.
Replacement Considerations
Compatible substitutes include other 2.54mm pitch single-row male headers from manufacturers such as Samtec or Molex, provided the contact count, terminal style, and mounting orientation match exactly.
