M22-6551042R

Headers, Receptacles, Female Sockets Overview

The M22-6551042R is a rectangular connector receptacle from the Harwin M22 series, designed for surface mount applications. It features a right-angle orientation with a 2.00mm (0.079 inch) pitch and accommodates 20 contacts arranged in two rows. The connector utilizes gold-plated phosphor bronze contacts housed in black polyamide insulation rated UL94 V-0. It supports board-to-board connections with a mating height of 1.50mm and operates within a temperature range of -40°C to +105°C.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount right-angle design for automated PCB assembly
• Gold-plated phosphor bronze contacts for reliable signal transmission
• Polyamide insulation housing with UL94 V-0 flammability rating
• Compatible with standard 2.00mm pitch mating headers

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections in compact electronic assemblies
• High-density circuit board stacking configurations
• Automated surface mount technology production lines
• Industrial control modules requiring robust vertical connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific suffix 'R' denotes the tape and reel packaging format required for automated pick-and-place equipment. Confirm the exact contact count and row configuration matches the target PCB footprint. Ensure compatibility with mating header part numbers from the same M22 series family to guarantee proper mechanical engagement and electrical continuity.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a right-angle surface mount receptacle is necessary for space-constrained designs. Consider the 2.00mm pitch requirement and the need for gold-plated contacts in high-reliability environments. Evaluate the thermal profile requirements against the specified operating temperature range and ensure the PCB layout supports the surface mount termination style.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the M22 series of rectangular connectors manufactured by Harwin Inc. The series is characterized by its 2.00mm pitch and availability in various mounting styles including through-hole and surface mount options. The M22-6551042R specifically represents the right-angle surface mount receptacle variant within this standardized connector ecosystem.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Harwin M22 series right-angle surface mount receptacles with identical 2.00mm pitch and compatible pin counts. Verify that alternative parts maintain the same contact material, plating thickness, and insulation flammability rating to ensure functional equivalence without redesigning the host PCB.
