1109424241

Overview

The Molex 1109424241 is a 4-position, 2.5mm pitch, double-row header connector designed for PCB mounting. It features a vertical through-hole termination with a 3.0mm mating height and a 6.0mm panel cutout requirement. The housing is constructed from PBT material, rated UL 94V-0, and operates within a temperature range of -40°C to +105°C. Rated at 3A per contact, it utilizes gold flash plating on the tin over nickel terminals for reliable signal and power transmission in compact electronic assemblies.

Feature Summary

• Double-row configuration enabling high-density circuit board layouts
• Vertical through-hole termination for secure PCB integration
• UL 94V-0 rated PBT housing for thermal stability
• Gold flash terminal plating ensuring corrosion resistance

Applications

• Consumer electronics internal interconnects
• Industrial control system boards
• Automotive infotainment modules
• Medical device instrumentation panels

Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm plating thickness and flange type. Ensure compatibility with corresponding receptacle part numbers from the same series. Confirm that the PCB footprint matches the specified 2.5mm pitch and hole dimensions before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a double-row header with a 2.5mm pitch. Ensure the application current does not exceed 3A per pin. Verify that the operating environment stays within the -40°C to +105°C range. Check that the mating receptacle has compatible locking mechanisms and housing materials.

Part Context

This part belongs to the Molex KK 254 Series family, characterized by its 2.54mm (often referred to as 2.5mm) pitch. It is widely used in general-purpose electronics for connecting harnesses to printed circuit boards. The series offers various configurations including single and double rows with different termination styles.

Replacement Considerations

Direct substitutes include other KK 254 series headers with identical 4-position, double-row specifications. Verify that any alternative maintains the same 3.0mm mating height and 6.0mm panel cutout requirements to ensure mechanical fit.
