Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Amphenol CONEC 43-01182 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Male Pins
• Number of Positions: 4
• Shell Size - Insert: M12-4
• Termination: Solder
• Contact Finish - Mating: Gold
• Orientation: A
• Ingress Protection: IP67
• Current Rating: 4A minimum
• Voltage Rating: 250V minimum
• Operating Temperature Range: Must encompass -30°C ~ 85°C

The Phoenix Contact 1552955 is identified as a suitable substitute based on alignment with these core electrical and mechanical parameters. This substitute maintains functional equivalence through matching connector architecture, contact specifications, environmental ratings, and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol CONEC 43-01182 and Phoenix Contact 1552955 are active, production-grade components with ROHS3 compliance certification. Selection between the primary part and substitute is based on availability, inventory levels, and application-specific requirements.

The 43-01182 maintains a minimum operating temperature of -30°C, while the 1552955 operates from -25°C. For applications requiring extended low-temperature performance below -25°C, the original Amphenol CONEC 43-01182 is the specified choice. Both parts meet IP67 ingress protection and carry identical electrical ratings (4A, 250V), ensuring functional equivalence in standard industrial environments.

The Phoenix Contact 1552955 features integrated shielding and a flammability rating of UL94 V-0, providing enhanced electrical noise rejection and superior flame resistance compared to the unshielded Amphenol CONEC design. These characteristics may provide additional benefits in noise-sensitive or high-temperature proximity applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol CONEC 43-01182 and Phoenix Contact 1552955 be used interchangeably? A: These connectors form a compatible mating pair due to identical shell size (M12-4), position count (4), and contact specifications. Mechanical and electrical substitution is valid when application temperature requirements do not exceed -25°C minimum operating temperature.

Q: What is the primary difference between these two connector types? A: The 43-01182 is a receptacle with male pins and threaded fastening, while the 1552955 is a plug with male pins and push-twist fastening. The 1552955 includes integrated shielding and enhanced flame resistance (UL94 V-0), whereas the 43-01182 is unshielded.

Q: Are there temperature limitations when substituting the Phoenix Contact 1552955 for the Amphenol CONEC 43-01182? A: The Phoenix Contact 1552955 operates within a minimum temperature range of -25°C, which is 5°C higher than the Amphenol CONEC specification of -30°C. Applications requiring operation below -25°C must use the original 43-01182.

Q: Do both parts carry the same electrical certifications? A: Both connectors are ROHS3 compliant and rated for identical electrical parameters: 4A current, 250V voltage. Both achieve IP67 ingress protection for dust and moisture resistance.

Q: How do the shell materials compare? A: The 43-01182 uses Copper Zinc shell material with nickel finish, while the 1552955 uses Zinc Die Cast with nickel finish. Both materials provide equivalent mechanical durability and corrosion resistance for the specified application environment.

Q: What is the difference in fastening mechanisms? A: The 43-01182 employs threaded fastening, while the 1552955 uses push-twist fastening. Both are mechanical locking methods suitable for panel-mount, through-hole bulkhead applications.

Q: Can the shielding feature of the 1552955 interfere with non-shielded applications? A: The integrated shielding in the Phoenix Contact 1552955 does not interfere with unshielded applications. It provides enhanced electromagnetic noise rejection without adverse effects in standard industrial environments.
