Engineering Selection Recommendations

The Amphenol CONEC 43-00092 is the direct substitute for the obsolete 43-00091. Both parts maintain identical electrical specifications (4A current rating, 250V voltage rating) and mechanical form factors (M12-4 shell size, 4-position configuration, screw termination). Both components satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial applications.

The primary distinction between these parts is cable opening tolerance. The 43-00092 accommodates larger cable diameters (6.00mm to 8.00mm) compared to the 43-00091 (4.00mm to 6.00mm). Selection between these variants depends on the cable gauge specified in the system design. The 43-00092 is the recommended choice for new designs and ongoing procurement due to its active product status and current availability.

Frequently Asked Questions (FAQ)

Q: Can 43-00092 directly replace 43-00091 in existing assemblies?

A: Direct replacement is possible if the cable diameter falls within the 43-00092 cable opening range of 6.00mm to 8.00mm. If the existing assembly uses cables in the 4.00mm to 6.00mm range, cable gauge compatibility must be verified before substitution.

Q: What is the significance of the cable opening difference between these parts?

A: Cable opening specifications define the acceptable cable diameter range for proper strain relief and connector seating. The 43-00092 accepts thicker cables than the 43-00091. Oversized or undersized cables relative to the connector opening may result in improper sealing or mechanical stress.

Q: Are the electrical performance characteristics identical between 43-00091 and 43-00092?

A: Yes. Both parts share identical current rating (4A), voltage rating (250V), contact finish (gold), and operating temperature range (-30°C to 85°C). Electrical performance is equivalent.

Q: Why is 43-00091 classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The 43-00092 serves as the active production equivalent and is the recommended part for new procurement.

Q: Are compliance certifications the same for both parts?

A: Yes. Both 43-00091 and 43-00092 are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.

Q: What packaging options are available?

A: The 43-00092 is supplied in bulk packaging. The 43-00091 packaging specification is not provided in the technical data.
