Substitute Part Grouping Explanation

The M22-5321005 qualifies as a direct substitute for the M22-5521005 based on the following alignment of critical electrical and mechanical parameters:

• Connector Series: Both parts belong to the M22 series from Harwin Inc.
• Pitch and Position Configuration: Identical 0.079" (2.00mm) mating pitch with 20 positions in a 2-row configuration
• Row Spacing: Both maintain 0.079" (2.00mm) row spacing
• Contact Type and Material: Both feature male pins with phosphor bronze material and gold mating finish
• Mounting and Termination: Both are surface mount connectors with solder termination
• Operating Temperature Range: Both operate across -40°C to 105°C
• Regulatory Compliance: Both are RoHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability rating
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is that M22-5321005 is Active status, whereas M22-5521005 is Obsolete, making the former the recommended long-term alternative.

Parameter Comparison

Engineering Selection Recommendations

The M22-5321005 is the appropriate substitute for the obsolete M22-5521005. Both components maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, row configuration, contact material, and operating temperature range. The substitute part carries Active product status, ensuring continued availability and manufacturer support. Both parts satisfy RoHS3 compliance and REACH requirements, with equivalent UL94 V-0 flammability certification. The transition from M22-5521005 to M22-5321005 presents no functional or compliance barriers for applications requiring rectangular connector headers in the M22 series.

Frequently Asked Questions (FAQ)

Q: Can M22-5321005 be used as a direct replacement for M22-5521005 in existing designs?

A: Yes. Both parts share identical pitch (0.079" / 2.00mm), position count (20), row configuration (2 rows), contact type (male pin), mounting method (surface mount), and termination (solder). Mechanical and electrical compatibility is maintained across all specified parameters.

Q: What is the primary reason for substitution?

A: M22-5521005 is classified as Obsolete. M22-5321005 is the Active equivalent within the M22 series, ensuring long-term availability and manufacturer support.

Q: Are there differences in current rating between these parts?

A: Yes. M22-5521005 is rated at 2A, while M22-5321005 is rated at 1A per contact. Applications requiring the full 2A rating per contact should be evaluated against the substitute's 1A specification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both M22-5521005 and M22-5321005 are RoHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: Are there packaging differences?

A: M22-5521005 packaging is not specified in available data. M22-5321005 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.
