M22-6550442R

Headers, Receptacles, Female Sockets Overview

The M22-6550442R is an 8-position receptacle connector from the Harwin M22 series. It features a 2.00mm (0.079 inch) pitch and utilizes a two-row configuration for board-to-board applications. The component employs surface mount technology with a right-angle orientation, designed for vertical integration into PCB layouts. Contacts are constructed from phosphor bronze and finished with gold flash plating to ensure reliable signal transmission. The housing is made of polyamide (PA6T), rated UL94 V-0 for flame resistance. It supports a mating stack height of 4.35mm or 6.55mm depending on the specific assembly configuration.

Headers, Receptacles, Female Sockets Feature Summary

• Right-angle surface mount design facilitates compact vertical stacking in dense electronic assemblies.
• Gold flash plated phosphor bronze contacts provide durable electrical conductivity and corrosion resistance.
• High-temperature PA6T insulation ensures stability and meets UL94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections requiring right-angle mounting
• Compact electronic devices with limited vertical space
• Industrial control modules needing high-temperature reliability

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific order includes the 'R' suffix, which denotes the right-angle variant. Confirm the required stack height matches the application needs, as the connector supports both 4.35mm and 6.55mm configurations. Ensure the receiving PCB footprint aligns with the surface mount right-angle specifications provided in the official datasheet.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a right-angle connection is mandatory for space-constrained designs. The 2.00mm pitch allows for moderate density routing compared to finer pitches. Consider the 8-position count for balanced I/O requirements. Verify that the operating temperature range of -40°C to +105°C suits the environmental conditions of the target equipment.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the M22 series, a family of connectors known for robust performance in demanding environments. The series offers various row counts and termination styles, but this specific part number is dedicated to the 8-position right-angle surface mount receptacle format. It pairs with corresponding headers from the same series.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2.00mm pitch, 8-position count, right-angle SMT form factor, and gold-plated contacts. Generic equivalents may lack the specific UL94 V-0 rating or precise stack height tolerances of the original M22 series design.
