Overview
The Oupiin 4077-04G00SB is a board connector featuring four contacts arranged in a single row. It utilizes a male configuration with straight orientation and a 2.54mm (0.1 inch) pitch. The component employs solder termination for secure PCB attachment and includes locking features to ensure stable mating. Constructed as a header, it supports through-hole mounting and is designed for reliable electrical interconnection within electronic assemblies.
Feature Summary
- Male pin header configuration for board-to-board or wire-to-board connections
- Integrated locking mechanism to secure mating interface stability
- Straight orientation design compatible with standard PCB layouts
- Solder termination method ensuring robust mechanical and electrical joints
Applications
- General purpose electronic circuit interconnections
- Consumer electronics assembly modules
- Industrial control board signal routing
- Automotive electronic subsystem connections
Procurement Notes
Verify the specific contact plating material and current rating requirements against the official datasheet before procurement. Confirm that the housing profile and locking mechanism align with the mating counterpart specifications. Ensure the selected variant matches the required terminal type and mounting orientation for the target PCB design.
Selection Notes
Select this component when a low-profile male header with locking capabilities is required. Consider the 2.54mm pitch compatibility with existing wiring harnesses or mating connectors. Evaluate the straight orientation against spatial constraints on the printed circuit board. Verify that the solder termination method suits the manufacturing process used.
Part Context
This part belongs to the Oupiin 4077 series of board connectors. The series offers various configurations including shrouded wafers and housings with different pin counts. The 4077-04G00SB specifically represents a four-position male header variant within this family, designed for applications requiring secure connection retention.
Replacement Considerations
Compatible substitutes include other 4-pin male headers with 2.54mm pitch and locking features from the same manufacturer series. Cross-reference dimensions such as body width and height to ensure physical fit. Verify electrical ratings and termination style match the original design requirements.
