1-794078-1

Headers, Male Pins Overview

The 1-794078-1 is a Mini-Universal MATE-N-LOK header connector manufactured by TE Connectivity AMP Connectors. It features a dual-row configuration with 22 positions and a 4.14 mm (0.163 inch) mating pitch. Designed for through-hole vertical PCB mounting, the unit utilizes brass pins with gold plating to ensure reliable signal transmission. The housing is constructed from white nylon with a UL 94 V-0 flammability rating. Rated for 600 VAC and up to 9.5 A depending on wire gauge, it operates within a temperature range of -55°C to 105°C.

• Vertical through-hole termination style for secure PCB integration
• Nylon insulation housing with UL 94 V-0 flame retardancy

Headers, Male Pins Applications

• Industrial control systems requiring robust power distribution
• Automotive electronics and engine management modules
• General-purpose electrical equipment and machinery
• Consumer appliance internal wiring interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and current rating requirements against the official datasheet before ordering. Confirm that the 22-position dual-row format matches the target PCB footprint. Ensure compatibility with mating sockets from the same Mini-Universal MATE-N-LOK series. Check for any recent product change notices regarding material updates or packaging variations.

Headers, Male Pins Selection Notes

Select this component when a high-current, vertically mounted header is required for durable applications. The gold plating offers superior performance in environments prone to oxidation compared to tin variants. Consider the 4.14 mm pitch for spacing constraints and the 600VAC rating for safety compliance. Evaluate thermal management needs as current capacity varies with wire gauge.

Headers, Male Pins Part Context

This part belongs to the Mini-Universal MATE-N-LOK family, a widely used line of rectangular connectors known for reliability in demanding environments. The series supports various row counts and termination styles, making it adaptable for diverse industrial and commercial uses. TE Connectivity continues to support this legacy line with updated documentation and compatible accessories.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 22-position dual-row headers from the Mini-Universal MATE-N-LOK series with matching 4.14 mm pitch. Verify that alternative parts maintain the same vertical orientation and through-hole termination method. Cross-reference pin dimensions and housing locking mechanisms to ensure mechanical interchangeability.
