5055781260

Headers, Male Pins Overview

Molex part number 5055781260 is a Micro-Lock Plus series PCB header featuring a single row of 12 male pin contacts with a 2.00mm pitch. Designed for surface mount right-angle installation, it utilizes brass terminals with matte tin plating and polyamide insulation rated UL94 V-0. The component supports a maximum voltage of 250V AC/DC and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Micro-Lock positive locking mechanism ensures secure mating with compatible receptacles.
• Shrouded design provides polarity keying and prevents misalignment during assembly.
• Right-angle surface mount termination facilitates compact board layout integration.

Headers, Male Pins Applications

• Wire-to-board signal interconnections
• Industrial control systems
• Automotive electronics

Headers, Male Pins Procurement Notes

Verify the specific contact plating configuration against project requirements, as datasheet variations indicate potential differences between gold and tin finishes for this series. Confirm that the matte tin version aligns with solderability standards if lead-free processes are mandated. Ensure compatibility with mating receptacles sharing the same 2.00mm pitch and shrouded geometry to maintain mechanical integrity.

Headers, Male Pins Selection Notes

Select this component when a right-angle, surface-mount header with a fixed 12-position count is required. The Micro-Lock system offers superior retention compared to standard headers. Verify that the operating environment stays within the specified thermal limits and that the board space accommodates the right-angle profile without obstructing adjacent components.

Headers, Male Pins Part Context

This connector belongs to Molex's Micro-Lock Plus family, engineered for high-reliability signal transmission in dense electronic assemblies. The series emphasizes robust mechanical locking and precise alignment, making it suitable for applications requiring frequent mating cycles or vibration resistance in automotive and industrial sectors.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 12-position, 2.00mm pitch, right-angle SMT headers from the same Micro-Lock Plus series, such as part numbers 505578-0671 (6-position) or 505578-0871 (8-position) for reduced counts, provided the locking mechanism and shroud style match the design constraints.
