436500821

Headers, Male Pins Overview

The Molex 43650-0821 is a Micro-Fit 3.0 series PCB header featuring an 8-position single-row configuration with a 3.00mm pitch. Designed for surface-mount technology, it utilizes a press-fit metal retention clip for secure board attachment and supports up to 8.5A current at 600V. The connector employs matte tin plating on brass contacts and is glow-wire capable, operating within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Surface-mount design with integrated press-fit metal retention clips for enhanced mechanical stability
• Glow-wire capable construction suitable for high thermal resistance requirements
• Single-row 8-circuit layout optimized for compact wire-to-board interconnections

Headers, Male Pins Applications

• Industrial automation control panels
• Consumer electronics power distribution
• Automotive internal wiring harnesses

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against official Molex documentation to ensure correct contact plating and retention mechanism specifications. Confirm that the surface-mount footprint matches the target PCB design guidelines. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-current surface-mount header is required for 3.00mm pitch applications. Ensure the design accommodates the vertical height constraints and the specific press-fit retention clip dimensions. Verify compatibility with mating receptacles from the same Micro-Fit 3.0 family to guarantee proper alignment and electrical continuity.

Headers, Male Pins Part Context

This part belongs to the Molex Micro-Fit 3.0 family, which provides reliable power delivery and signal transmission solutions. The series is characterized by its robust design, supporting both through-hole and surface-mount configurations. It is widely utilized in industrial and automotive sectors where space efficiency and connection reliability are critical priorities.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Molex Micro-Fit 3.0 headers with identical 8-position single-row layouts and surface-mount footprints. Verify that alternative parts maintain the same 3.00mm pitch, current rating, and glow-wire capability to ensure functional equivalence without redesigning the PCB assembly.
