Procurement Notes
Verify the specific ordering suffix against official Amphenol documentation to confirm contact finish and insulation material specifications. Ensure the selected variant matches the required mounting style and current rating for the target application. Cross-reference the manufacturer's latest datasheet to confirm availability and compliance status before finalizing procurement orders.
Selection Notes
Select this component when a 4.2 mm pitch power header is required for high-current applications up to 9 A. The dual-row configuration allows for efficient space utilization in dense assemblies. Verify that the operating temperature range meets environmental requirements and that the right-angle form factor aligns with mechanical constraints.
Part Context
This connector belongs to the Minitek Pwr 4.2 family, which provides standardized solutions for power distribution in electronic systems. The series is characterized by its 4.2 mm spacing, offering a balance between current capacity and board density. It is widely used in industrial and commercial electronics where reliable power interconnects are critical.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Generic replacements may differ in pitch, current rating, or mounting style. Verify mechanical dimensions and electrical ratings before substituting.
