5055681281

Headers, Male Pins Overview

The Molex 505568-1281 is a Micro-Lock Plus series header featuring a 1.25mm pitch and 12 positions in a single row. Designed for surface mount (SMD/SMT) installation, it utilizes right-angle termination with gold-plated male pins. The component operates within a temperature range of -40°C to +105°C and supports a voltage rating of 50VAC/DC with a current capacity of 1.5A. Constructed from black polyamide housing with UL 94 V-0 flammability ratings, it ensures reliable signal integrity in compact electronic assemblies.

Headers, Male Pins Procurement Notes

Verify the specific suffix designation against official Molex documentation to confirm pin count, plating thickness, and packaging configuration. Ensure compatibility with mating receptacles regarding polarity and mechanical retention features. Cross-reference RoHS compliance status and lead-free soldering requirements with current manufacturer specifications before integration into production workflows.

Headers, Male Pins Selection Notes

Select this component for applications requiring high-density signal routing in constrained spaces. The 1.25mm pitch allows for increased circuit density compared to standard 2.54mm headers. Evaluate thermal management needs against the 105°C maximum operating limit. Confirm that the right-angle orientation aligns with the board layout constraints and mating connector accessibility requirements.

Headers, Male Pins Part Context

This part belongs to the Molex Micro-Lock Plus family, engineered for robust connectivity in demanding environments. The series emphasizes secure locking mechanisms and miniaturization, catering to modern electronics trends toward smaller form factors. It complements Molex's broader portfolio of wire-to-board and board-to-board solutions designed for reliability across automotive and industrial sectors.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Molex Micro-Lock Plus headers with identical 1.25mm pitch, 12-position count, and right-angle SMD mounting. Verify equivalent current ratings and voltage withstand capabilities. Alternative manufacturers may offer compatible geometries but require validation of locking mechanism engagement forces and contact material specifications.
