Engineering Selection Recommendations

The M22-5320546 is the designated substitute for the obsolete M22-5520546. Both components maintain identical compliance certifications including ROHS3 and REACH Unaffected status, ensuring regulatory alignment for applications requiring these standards.

The primary distinction between the main part and substitute is product status: M22-5520546 is Obsolete while M22-5320546 is Active, with current inventory availability of 2995 pieces. This transition to an active product ensures long-term supply chain viability.

A secondary consideration is the current rating differential: M22-5520546 is rated at 2A total capacity, while M22-5320546 is rated at 1A per contact. For applications operating at or near the 2A specification of the original part, this reduction in per-contact current capacity requires circuit-level evaluation to confirm compatibility with existing designs.

Contact length variation exists between the parts: M22-5520546 features 0.165" (4.20mm) mating contact length compared to 0.138" (4.60mm) for M22-5320546. This difference may affect mating force characteristics and connector engagement depth in existing receptacle designs.

Frequently Asked Questions (FAQ)

Q: Can M22-5320546 directly replace M22-5520546 in existing designs?

A: M22-5320546 is electrically and mechanically compatible based on pitch, position count, row configuration, and thermal operating range. However, the reduced per-contact current rating (1A versus 2A) and shorter mating contact length (4.60mm versus 4.20mm) require design verification before implementation.

Q: What is the significance of the Obsolete status for M22-5520546?

A: Obsolete status indicates the part is no longer manufactured or supported by Harwin Inc. Transition to M22-5320546, which carries Active status, ensures continued availability and supply chain support for future production requirements.

Q: Are both parts RoHS and REACH compliant?

A: Both M22-5520546 and M22-5320546 are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for applications subject to these standards.

Q: How do the current ratings differ between these parts?

A: M22-5520546 is rated for 2A total current capacity. M22-5320546 is rated for 1A per contact. For applications requiring the full 2A capacity of the original part, circuit analysis is necessary to determine if the reduced per-contact rating of the substitute is acceptable.

Q: What is the difference in contact length between these connectors?

A: M22-5520546 has a mating contact length of 0.165" (4.20mm), while M22-5320546 has a mating contact length of 0.138" (4.60mm). This 0.7mm difference may affect engagement characteristics with existing mating receptacles and should be evaluated for mechanical compatibility.

Q: Do both parts use the same insulation and contact materials?

A: Both parts utilize Polyamide (PA6T) Nylon 6T insulation material and Phosphor Bronze contact material with Tin finish, ensuring material compatibility and equivalent electrical performance characteristics.
