Overview
The Oupiin 4771-07TRB is a through-hole header connector featuring 7 positions with a 0.156 inch (3.96mm) pitch. It utilizes a right-angle male pin configuration designed for PCB mounting. The component belongs to the 4771 series, which provides a current rating of 7A and incorporates locking features to ensure secure mating. The insulator material meets UL94V-0 or UL94V-2 standards, ensuring electrical safety and thermal stability in standard electronic assemblies.
Feature Summary
- Right-angle male pin configuration for efficient board space utilization
- Integrated locking mechanism to maintain secure connection integrity
- Insulator construction compliant with UL94V-0 or UL94V-2 flammability ratings
Applications
- General-purpose electronic circuit interconnections
- Consumer electronics assembly boards
- Industrial control module wiring
Procurement Notes
Verify that the specific part number matches the required 7-position count and right-angle orientation. Confirm that the supplier documentation explicitly lists the 4771-07TRB designation to avoid confusion with similar straight or different position variants within the same series. Ensure compatibility with the target PCB hole spacing.
Selection Notes
Select this component when a right-angle male header is required for 3.96mm pitch applications. The 7-position count must align with the specific signal or power line requirements of the design. Consider the locking feature if vibration resistance is necessary for the intended operational environment.
Part Context
This connector is part of the broader 4771 series produced by Oupiin Enterprise. The series includes various configurations such as straight headers, wafer components, and different pin counts ranging from 2 to 10 positions. The 4771-07TRB specifically represents the right-angle male variant with seven contacts.
Replacement Considerations
Compatible substitutes include other 4771 series right-angle headers with identical 7-position layouts and 3.96mm pitch. Verify mechanical dimensions and terminal plating specifications before substitution to ensure proper fit and electrical performance.
