Overview
The Oupiin 4973-20TSB is a 4.20mm pitch wire-to-board connector component belonging to the 4973 series. It functions as a straight (STR) wafer housing designed for PCB mounting. The part supports configurations with 2 to 20 pins, facilitating secure electrical connections between wires and circuit boards in single-row arrangements.
Feature Summary
- Features a 4.20mm pitch design for standardized spacing
- Constructed as a straight wafer housing for direct PCB integration
- Supports variable pin counts ranging from 2 to 20 positions
Applications
- General electronic equipment interconnects
- Consumer appliance wiring harnesses
- Industrial control panel connections
Procurement Notes
Verify the specific pin count required by your design, as the base model number indicates the series but the suffix determines the exact position count. Confirm that the mating terminals are compatible with the 4.20mm pitch specification. Ensure RoHS compliance requirements are met if applicable to your manufacturing standards. Cross-reference the straight orientation against board layout constraints.
Selection Notes
Select this component when a 4.20mm pitch is necessary for space-constrained applications requiring a low-profile straight connection. Consider the 2 to 20 pin flexibility for varying channel requirements. Evaluate the mechanical retention provided by the wafer design against vibration environments. Compare against angled options if board clearance is limited in the vertical direction.
Part Context
This part belongs to the Oupiin 4973 series of wire-to-board connectors. The series offers various housing types including male/female housings and wafers in both straight and right-angle configurations. The 4.20mm pitch distinguishes it from other common pitches like 3.96mm or 5.08mm, providing a balance between current capacity and density.
Replacement Considerations
Direct substitutes must match the 4.20mm pitch and straight wafer form factor. Generic industry equivalents may vary in locking mechanism details and material specifications. Verify dimensional compatibility with existing PCB footprints before substitution.
