1200770004

Overview

The Molex 120077-0004 is a 4-position, single-row, vertical through-hole header connector from the KK® 2.54mm Wire-to-Board series. It features a 2.54 mm pitch and is designed for PCB mounting with a right-angle orientation. The housing is constructed from black polyamide (PA) material, rated UL 94V-0, and includes a polarizing key to ensure correct mating alignment. The connector supports wire gauges ranging from 30 to 22 AWG and utilizes a shrouded design for enhanced stability during assembly.

Feature Summary

• Vertical through-hole mounting configuration for standard PCB integration
• Shrouded housing design provides mechanical stability and prevents misalignment
• Polarizing key ensures correct orientation during mating processes
• Compatible with standard 2.54 mm pitch wire-to-board cable assemblies

Applications

• Consumer electronics internal interconnects
• Industrial control board signal routing
• Computer peripheral circuit connections

Procurement Notes

Verify that the specific order quantity matches the standard packaging requirements of the manufacturer. Confirm that the PCB footprint dimensions align precisely with the datasheet drawings before finalizing procurement. Ensure compatibility with existing assembly equipment regarding lead form and height specifications.

Selection Notes

Select this component when a low-profile, vertical connection is required for 4-wire circuits. Ensure the operating temperature range meets the application's environmental demands. Verify that the current rating per contact is sufficient for the intended load. Consider the shrouded design benefits if lateral stability is critical for the assembly process.

Part Context

This part belongs to the KK® 2.54mm Wire-to-Board family, a widely used interconnect system known for its compact size and reliability. The series offers various configurations including headers, housings, and terminals. This specific model represents a fixed header variant designed for permanent soldering to printed circuit boards.

Replacement Considerations

Cross-reference with other KK® 2.54mm series headers from Molex or compatible third-party manufacturers offering identical 2.54 mm pitch and 4-position shrouded designs. Verify pin count, housing color, and terminal plating specifications to ensure functional equivalence.
