Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-5321305 is determined by the following critical parameters:

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

The M22-5322205 qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference is the number of positions (44 vs. 26), which represents a configuration variant within the same product family rather than a fundamental incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The M22-5322205 is available as an active product from Harwin Inc., whereas the M22-5321305 is obsolete. Both components share identical electrical and mechanical specifications across all critical parameters, including pitch, contact material, termination method, operating temperature range, and current rating.

Selection of the M22-5322205 provides the advantage of current product availability and ongoing manufacturer support. Both parts maintain equivalent RoHS3 compliance and REACH unaffected status. The primary design consideration is the increased position count (44 vs. 26), which requires evaluation against specific application requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the M22-5322205 directly replace the M22-5321305 in existing designs?

A: Direct replacement depends on application requirements. Both connectors share identical electrical and mechanical characteristics including pitch, contact material, and operating temperature range. The M22-5322205 provides 44 positions versus 26 positions in the original part. If the application requires exactly 26 positions, the additional 18 positions in the substitute must be accommodated or left unloaded in the design.

Q: What is the significance of the "Cuttable" connector type designation?

A: The cuttable designation indicates that both the M22-5321305 and M22-5322205 can be mechanically separated into smaller connector segments. This allows customization of position count to match specific application requirements.

Q: Are there compliance differences between the two parts?

A: No. Both the M22-5321305 and M22-5322205 maintain identical compliance certifications: RoHS3 compliant, REACH unaffected, UL94 V-0 flammability rating, and Moisture Sensitivity Level 1 (unlimited).

Q: What is the impact of the product status difference?

A: The M22-5321305 is classified as obsolete, indicating discontinued manufacturing. The M22-5322205 maintains active product status, ensuring continued availability, technical support, and supply chain reliability from Harwin Inc.

Q: Are the mating pitch and row spacing identical between these connectors?

A: Yes. Both connectors feature 0.079" (2.00mm) mating pitch and 0.079" (2.00mm) row spacing, ensuring mechanical and electrical compatibility with mating connectors designed for the M22 series.
