Overview
The Oupiin 4973-18TSB is a male pin header connector from the 4973 series, designed for through-hole PCB mounting. It features an 18-position configuration with a 0.165-inch (4.20mm) pitch. The component utilizes a shrouded wafer design to ensure proper alignment and retention on the printed circuit board. This connector supports wire gauges ranging from 18AWG to 22AWG and provides a current rating of 7A. The housing material meets UL 94V-2 flammability standards.
Feature Summary
- Through-hole mounting technology for secure PCB attachment
- Shrouded single-row design for precise alignment
- Integrated locking mechanism for reliable mating
- Compatible with standard wire gauges
Applications
- General electronic equipment interconnections
- Consumer appliance wiring harnesses
- Industrial control panel connections
- Wire-to-board signal transmission
Procurement Notes
Verify that the specific suffix 'TSB' corresponds to the straight terminal variant as documented in official Oupiin datasheets. Confirm that the 18-position count matches the required circuit density. Ensure compatibility with mating terminals specified for the 4973 series. Check RoHS compliance status if required by project specifications. Validate that the through-hole footprint aligns with the PCB layout guidelines provided in the manufacturer documentation.
Selection Notes
Select this component when a 4.20mm pitch male header is required for through-hole assembly. Consider the 18-position count for specific channel requirements. Evaluate the 7A current rating against the application's electrical load. Ensure the shrouded design fits within the available spatial constraints. Verify that the wire gauge range accommodates the intended cable specifications.
Part Context
The 4973-18TSB belongs to Oupiin's 4973 series of 4.2mm wire-to-board connectors. This series is characterized by its robust construction and snap-in posts for PCB retention. The family includes various position counts and terminal orientations, serving as a standardized solution for internal wiring in electronics. The series emphasizes secure locking and reliable connection performance.
Replacement Considerations
Direct substitutes must match the 4.20mm pitch, 18-position count, and through-hole mounting style. Verify that alternative components support the same 7A current rating and wire gauge range. Ensure the replacement part maintains the shrouded male pin configuration. Cross-reference mechanical dimensions to guarantee PCB footprint compatibility.
