M22-5320905R Equivalent & Substitute Parts

Part Overview

The M22-5320905R is a rectangular connector header manufactured by Harwin Inc., designed for surface mount board-to-board applications. This 18-position, 2-row connector operates across -40°C to 105°C and features gold-plated phosphor bronze contacts rated at 1A per contact. The part is currently listed as obsolete, necessitating identification of active equivalent components for ongoing design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-5320905R is determined by the following critical parameters that must remain constant or compatible:

• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Operating Temperature Range: -40°C ~ 105°C
• Current Rating: 1A per Contact
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Insulation Material: Polyamide (PA6T), Nylon 6T
• Material Flammability Rating: UL94 V-0
• Series: M22

The M22-5321005 qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference is an increase in position count from 18 to 20 positions, which is permissible when the application can accommodate the additional connector length and the extra positions are either utilized or left unloaded.

Parameter Comparison

Engineering Selection Recommendations

The M22-5321005 is an active product with full ROHS3 compliance and REACH unaffected status, making it suitable for procurement in applications where the M22-5320905R is no longer available. Both parts maintain identical electrical performance characteristics, thermal ratings, and contact specifications. The 20-position configuration of the M22-5321005 accommodates the 18-position requirement of the original design, with two additional positions available for future expansion or left unloaded as required by the application. Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating, ensuring equivalent reliability in equivalent operating environments.

Frequently Asked Questions (FAQ)

Q: Can the M22-5321005 directly replace the M22-5320905R in existing designs?

A: The M22-5321005 is mechanically and electrically compatible with the M22-5320905R. The primary difference is the increased position count from 18 to 20. If the PCB layout can accommodate the additional connector length, direct substitution is feasible. If space constraints exist, the design must be evaluated for compatibility.

Q: What is the physical size difference between these two connectors?

A: Both connectors share identical pitch (2.00mm), row spacing (2.00mm), and mounting type. The M22-5321005 is longer due to the additional two positions. Exact dimensional differences are determined by the position-to-length ratio of the M22 series.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts feature identical contact material (phosphor bronze), contact finish (gold), current rating (1A per contact), and operating temperature range (-40°C to 105°C). Electrical performance is equivalent.

Q: Why is the M22-5320905R listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The M22-5321005 remains in active production and provides equivalent functionality with additional position capacity.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the M22-5320905R and M22-5321005 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can unused positions on the M22-5321005 be left unloaded?

A: Yes. The connector is designed as a cuttable header with all positions loaded. Unused positions can remain unconnected in the application without affecting the performance of loaded positions.
