Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact plating thickness, and termination style. Ensure the selected variant matches the required board layout and current carrying capacity for the target application environment.
Selection Notes
Select this component for high-current power delivery requiring a 4.2 mm spacing. Confirm that the 9 A rating aligns with the circuit requirements. Verify compatibility with mating sockets from the same Minitek Power4.2 family to ensure proper mechanical engagement and electrical continuity.
Part Context
This part belongs to the Minitek Power4.2 line, designed for robust power-to-board connections. The series offers various position counts and termination options, providing flexibility for different PCB layouts while maintaining consistent electrical performance and mechanical reliability across the product family.
Replacement Considerations
Compatible substitutes include other 20-position, 4.2 mm pitch dual-row headers from the Minitek Power4.2 series, such as the 10127820-2024LCLF or 10127820-2022GLF, provided they match the vertical orientation and gold contact specifications.
