Overview
The Oupiin 4771-04TSB is a 3.96mm pitch wafer connector designed for wire-to-board applications. It features a single row configuration with four positions, accommodating wire gauges ranging from 18AWG to 24AWG. The component utilizes a locking ramp mechanism to secure mating connections and ensures reliable electrical performance within the 4771 series architecture.
Feature Summary
- Single row wafer design for compact board integration
- Locking ramp structure ensures secure mating retention
- Compatible with standard 18AWG to 24AWG wire gauges
Applications
- Wire-to-board interconnections in consumer electronics
- Internal wiring harnesses for industrial control panels
- Signal distribution in telecommunications equipment
Procurement Notes
Verify that the specific part number matches the required pin count and pitch specifications for your assembly. Confirm compatibility with the corresponding male terminals from the 4771 series. Ensure the housing material meets the necessary UL flammability ratings for your application environment before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, single-row solution is required for 3.96mm spacing. Consider the locking feature for vibration resistance. Evaluate the current rating requirements against the connected wire gauge to ensure safe operation within the specified thermal limits of the connector system.
Part Context
This part belongs to the Oupiin 4771 series, which provides industry-standard 3.96mm spacing solutions. The series includes various housings and wafers designed for robust dual contact connections. These components are widely used in applications requiring reliable wire-to-board interfaces with standardized dimensions.
Replacement Considerations
Direct substitutes include other manufacturers' 3.96mm pitch single-row wafers with identical locking mechanisms. Verify pin count, profile height, and terminal compatibility before cross-referencing alternative brands for equivalent performance.
