Substitute Part Grouping Explanation

Substitution eligibility for the 3M 951105-4620-AR-TP is determined by the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (5)
Mating pitch (0.079" / 2.00mm)
Mounting configuration (Surface Mount, Right Angle)
Termination method (Solder)
Contact finish (Gold)
Flammability rating (UL94 V-0)
Moisture sensitivity level (MSL 1)

The Harwin Inc. M22-5330505 meets all primary substitution criteria. This part maintains identical position count, pitch, mounting type, and termination method. Both connectors feature gold-plated mating contacts, UL94 V-0 flammability compliance, and MSL 1 moisture sensitivity classification.

Engineering Selection Recommendations

The Harwin M22-5330505 is the primary substitute for the obsolete 3M 951105-4620-AR-TP. Selection rationale is based on the following factors:

Product Status: The 3M part is obsolete, while the Harwin alternative is active and currently in production. This ensures long-term availability and supply chain continuity.

Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements and maintain MSL 1 moisture sensitivity classification. Both are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Electrical & Mechanical Compatibility: The substitute maintains identical mating pitch (0.079" / 2.00mm), position count (5), mounting configuration (surface mount right-angle), and termination method (solder). Contact geometry and finish specifications are equivalent.

Performance Considerations: The Harwin part provides higher current rating (2A per contact versus 1A) and extended lower operating temperature limit (-40°C versus -25°C), offering improved performance margins. Contact length variance (0.165" versus 0.175") is within acceptable tolerance for board-to-board mating applications.

Material Differences: The substitute uses polyamide (PA6T) nylon insulation and brass contacts in place of thermoplastic insulation and copper alloy contacts. These material substitutions are functionally equivalent for the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-5330505 directly replace the 3M 951105-4620-AR-TP in existing designs?

A: Yes. Both connectors share identical mating pitch (2.00mm), position count (5), mounting type (surface mount right-angle), and termination method (solder). Mechanical and electrical compatibility is maintained across all specified parameters.

Q: What is the significance of the "Cuttable" designation on the Harwin part?

A: The Harwin M22-5330505 features a cuttable header design, allowing the connector to be segmented to custom position counts if required. This does not affect compatibility with the standard 5-position configuration.

Q: Are there differences in contact length between these parts?

A: The mating contact length differs slightly: 3M part is 0.175" (4.45mm) while the Harwin part is 0.165" (4.20mm). This 0.010" (0.25mm) difference is within acceptable tolerance for board-to-board mating applications and does not affect functional compatibility.

Q: Does the higher current rating of the Harwin part affect compatibility?

A: No. The Harwin M22-5330505 is rated for 2A per contact compared to 1A for the 3M part. Higher current capacity provides additional performance margin and does not create compatibility issues in applications designed for the lower rating.

Q: What is the temperature operating range difference?

A: The Harwin part extends the lower operating temperature limit to -40°C compared to -25°C for the 3M part. The upper limit remains 105°C for both. This expanded range provides greater flexibility for temperature-sensitive applications.

Q: Are both parts RoHS compliant?

A: The Harwin M22-5330505 is explicitly ROHS3 compliant and REACH unaffected. Compliance information for the 3M part is not provided in the available specifications.

Q: What packaging is available for the substitute part?

A: The Harwin M22-5330505 is supplied in bulk packaging with 4095 pieces currently in stock.
