Parameter Comparison

Engineering Selection Recommendations

The Amphenol CONEC 43-01226 serves as a direct functional substitute for the obsolete TE Connectivity 3-2172065-2 circular connector. Both components share identical mechanical and electrical interface specifications for the M12-4 connector class, including mounting configuration, termination method, and ingress protection rating.

The 43-01226 is classified as an active product with ROHS3 compliance, providing superior long-term supply chain availability compared to the obsolete 3-2172065-2. The substitute part exceeds the original voltage specification (250V vs. 125V) and maintains equivalent current handling capacity (4A).

The primary technical difference is the contact finish specification: the 43-01226 features gold-plated mating contacts compared to tin plating on the original part. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environmental conditions. The operating temperature range of the 43-01226 (-30°C ~ 85°C) covers the upper portion of the original specification (-40°C ~ 85°C); applications requiring operation below -30°C require evaluation against specific system requirements.

Both components maintain MSL 1 (Unlimited) moisture sensitivity classification and are suitable for automotive and industrial applications requiring IP67 environmental sealing.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol CONEC 43-01226 directly replace the TE Connectivity 3-2172065-2 in existing designs?

A: The 43-01226 maintains mechanical and electrical interface compatibility with the 3-2172065-2. Both connectors share identical M12-4 shell size, 4-position configuration, panel mount bulkhead mounting, solder termination, and IP67 ingress protection. The substitute part meets or exceeds the original electrical specifications.

Q: What is the significance of the contact finish difference between tin and gold plating?

A: The 3-2172065-2 features tin-plated mating contacts, while the 43-01226 features gold-plated contacts. Gold plating provides superior corrosion resistance and contact reliability, particularly in high-humidity or corrosive environments. Both finishes are suitable for solder termination applications.

Q: Does the higher voltage rating of the 43-01226 (250V vs. 125V) affect compatibility?

A: The 43-01226 voltage rating of 250V exceeds the original 125V specification. Higher voltage ratings indicate enhanced dielectric strength and insulation capability. The substitute part is suitable for applications operating at or below the original 125V specification.

Q: Are there temperature range considerations when substituting the 43-01226?

A: The 43-01226 operating temperature range is -30°C ~ 85°C, compared to the original -40°C ~ 85°C. Applications requiring operation below -30°C must be evaluated against specific system thermal requirements. The upper temperature limit of 85°C is identical for both parts.

Q: What is the difference in product status between the two parts?

A: The 3-2172065-2 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 43-01226 is classified as active, indicating current production and ongoing supply chain support. Active product status ensures long-term component availability for new designs and field service applications.

Q: Are both parts RoHS compliant?

A: The 3-2172065-2 is RoHS Compliant. The 43-01226 is ROHS3 Compliant, representing compliance with the most current RoHS directive revision. Both parts meet environmental and hazardous substance restriction requirements.

Q: What is the MSL rating for both connectors?

A: Both the 3-2172065-2 and 43-01226 carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no moisture sensitivity precautions are required during storage, handling, or assembly.
