Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol CONEC 43-01183 are identified based on electrical and mechanical compatibility within the circular connector category. The substitution criteria are strictly limited to the following parameters:

Critical Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: M12-4
• Termination Method: Solder
• Mounting Type: Panel Mount, Through Hole
• Ingress Protection: IP67
• Current Rating: 4A
• Voltage Rating: 250V
• Contact Finish - Mating: Gold
• Shielding: Shielded
• RoHS Compliance: ROHS3 Compliant

The Phoenix Contact 1552955 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. Variations in connector type (plug versus receptacle), fastening mechanism (threaded versus push-twist), shell material composition, and operating temperature range do not preclude substitution when the core functional requirements are met.

Engineering Selection Recommendations

Amphenol CONEC 43-01183 (Primary Part)

The Amphenol CONEC 43-01183 is the specified component and remains the first choice for new designs and existing applications. This part is active in production with adequate inventory (642 units in stock). It carries ROHS3 compliance and is unaffected by REACH regulations, providing regulatory certainty for applications in restricted markets. The operating temperature range of -30°C to 85°C accommodates extended low-temperature environments.

Phoenix Contact 1552955 (Substitute Part)

The Phoenix Contact 1552955 serves as a functional substitute when the Amphenol CONEC 43-01183 is unavailable. This part maintains all critical electrical parameters and mechanical compatibility for M12-4 circular connector applications. The Phoenix Contact part is also ROHS3 compliant and carries higher inventory availability (1112 units in stock). The operating temperature range of -25°C to 85°C is suitable for most industrial applications, with the exception of systems requiring operation below -25°C. The push-twist fastening mechanism differs from the threaded fastening of the primary part but does not affect electrical performance or mechanical fit within the M12-4 standard envelope.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1552955 be used as a direct replacement for the Amphenol CONEC 43-01183?

A: The Phoenix Contact 1552955 is electrically and mechanically compatible for applications operating within the -25°C to 85°C temperature range. Both parts maintain 4-position M12-4 configuration, 4A current rating, 250V voltage rating, IP67 ingress protection, and gold-plated mating contacts. The fastening mechanism differs (push-twist versus threaded), but this does not affect connector performance within the M12-4 standard.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Connector type—Amphenol CONEC is a receptacle while Phoenix Contact is a plug; (2) Fastening type—Amphenol CONEC uses threaded fastening while Phoenix Contact uses push-twist; (3) Operating temperature minimum—Amphenol CONEC operates to -30°C while Phoenix Contact operates to -25°C; (4) Shell material—Amphenol CONEC uses copper zinc while Phoenix Contact uses zinc die cast; (5) REACH status—Amphenol CONEC is unaffected while Phoenix Contact is affected.

Q: Are both parts RoHS compliant?

A: Yes, both the Amphenol CONEC 43-01183 and Phoenix Contact 1552955 are ROHS3 compliant. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the significance of the M12-4 shell size designation?

A: M12-4 is the standardized shell size and position count for these circular connectors. The "M12" refers to the 12mm metric shell diameter, and the "4" indicates 4 contact positions. Both substitute parts conform to this standard, ensuring mechanical interchangeability within the M12-4 connector ecosystem.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: Both parts support operation up to 85°C. For applications requiring operation below -25°C, the Amphenol CONEC 43-01183 is required due to its -30°C minimum operating temperature. The Phoenix Contact 1552955 is limited to -25°C minimum.

Q: What is the current and voltage rating for these connectors?

A: Both the Amphenol CONEC 43-01183 and Phoenix Contact 1552955 are rated for 4A continuous current and 250V maximum voltage. These ratings apply to all four contact positions.

Q: Are these parts suitable for outdoor or wet environments?

A: Yes, both parts carry IP67 ingress protection rating, indicating dust-tight and waterproof construction. This rating qualifies both connectors for outdoor and wet industrial environments.
