10-89-1421

Headers, Male Pins Overview

The Molex 10-89-1421 is a vertical PCB header connector from the KK-254 series, designed for board-to-board or wire-to-board interconnections. It features a 2.54 mm pitch and provides 42 circuits in a single row configuration. The housing is constructed from black polybutylene terephthalate (PBT) resin, rated UL 94V-0 for flammability. The contacts are brass terminals with a tin plating to ensure reliable conductivity and corrosion resistance. This component supports through-hole termination on printed circuit boards.

Headers, Male Pins Feature Summary

• Vertical orientation for standard PCB mounting
• Single-row design accommodating 42 signal paths
• Tin-plated brass contacts for durability
• Black PBT housing with UL 94V-0 rating

Headers, Male Pins Applications

• Consumer electronics assembly
• Industrial control systems
• Automotive internal wiring

Headers, Male Pins Procurement Notes

Verify that the specific order matches the 42-position requirement and single-row layout. Confirm the tin plating specification aligns with environmental exposure needs. Ensure the vertical header style fits the mechanical constraints of the target PCB stack-up. Cross-reference the datasheet for exact mating partner dimensions to guarantee proper engagement.

Headers, Male Pins Selection Notes

Select this part when a high-density, low-profile connection is required for 2.54 mm pitch applications. The vertical form factor is suitable for standard surface area mounting. Consider the 42-circuit count against available board space. The tin finish offers a balance between cost and performance for general-purpose environments.

Headers, Male Pins Part Context

This component belongs to the KK-254 family, a widely used line of micro-terminal connectors known for their compact size and reliability. The series is characterized by its 2.54 mm pitch, which facilitates easy handling and automated assembly. The 10-89-1421 specifically represents the 42-position variant within this extensive catalog of interconnect solutions.

Headers, Male Pins Replacement Considerations

Direct substitutes include other manufacturers' 2.54 mm pitch headers with identical pin counts and vertical orientation. Verify mechanical compatibility with mating sockets before substitution. Ensure electrical ratings meet or exceed the original application requirements.
