Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-2172072-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Shell Size - Insert: M12-4
• Termination Type: Solder
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Fastening Type: Threaded
• Current Rating: 4A
• Voltage Rating: 250V
• Contact Finish - Mating: Gold
• Orientation: A

Acceptable Variation Parameters:

• Connector Type: Receptacle or Plug configurations with female sockets
• Ingress Protection: IP67 or higher (IP68 is superior; IP67 is acceptable)
• Operating Temperature Range: Must encompass or exceed the required operating window
• Shell Material: Brass or Copper Zinc with Nickel finish
• Product Status: Active status preferred for ongoing availability

The substitute part Amphenol CONEC 43-01200 meets these criteria with documented compatibility across all mandatory parameters.

Engineering Selection Recommendations

Primary Substitute: Amphenol CONEC 43-01200

The Amphenol CONEC 43-01200 is the qualified substitute for the obsolete TE Connectivity 3-2172072-2. Selection is based on the following engineering criteria:

Compliance and Regulatory Alignment:

• Both parts maintain ROHS3 compliance, satisfying environmental and hazardous substance restrictions
• Both parts carry EAR99 export classification and identical HTSUS commodity codes, ensuring regulatory consistency
• Moisture Sensitivity Level 1 (Unlimited) on both parts eliminates moisture-related handling constraints

Electrical and Mechanical Compatibility:

• Identical electrical ratings (4A current, 250V voltage) ensure direct functional equivalence
• Matching M12-4 shell size, 4-position configuration, and solder termination provide mechanical interchangeability
• Identical fastening (threaded), mounting (panel mount, through hole, right angle), and orientation (A) confirm installation compatibility
• Gold-plated mating contacts on both parts ensure equivalent signal integrity and corrosion resistance

Operational Suitability:

• The Amphenol substitute operates across -30°C to 85°C, encompassing the upper portion of the original -40°C to 85°C range. Applications requiring operation below -30°C require verification against specific system requirements
• IP67 ingress protection on the substitute is functionally compatible with IP68 applications, as IP67 (dust tight, waterproof) meets or exceeds most industrial and automotive environmental demands
• Active product status of the Amphenol part ensures ongoing availability and supply chain continuity

Connector Type Consideration: The substitute is classified as a Plug configuration versus the original Receptacle. Both feature female sockets and are designed for mating with complementary connector types in M12 circular connector systems. Verification of mating connector compatibility within the specific application is required.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol CONEC 43-01200 directly replace the TE Connectivity 3-2172072-2 in existing assemblies?

A: The Amphenol substitute matches all mandatory electrical and mechanical parameters, including current rating, voltage rating, position count, shell size, termination type, and mounting configuration. Direct replacement is supported for applications operating within the -30°C to 85°C temperature range and where IP67 ingress protection is acceptable. Connector type differences (Plug versus Receptacle) require verification that mating connectors in the system are compatible with the substitute configuration.

Q: What is the difference between the IP68 rating on the original part and the IP67 rating on the substitute?

A: IP68 provides dust tight and waterproof protection with continuous immersion capability. IP67 provides dust tight and waterproof protection with temporary immersion capability. For applications requiring continuous immersion or extended submersion, the original IP68 specification should be retained. For standard industrial and automotive applications with splash and temporary water exposure, IP67 is functionally equivalent.

Q: Are there temperature range differences that affect substitution?

A: The original part operates from -40°C to 85°C. The substitute operates from -30°C to 85°C. Applications requiring operation below -30°C cannot use the Amphenol substitute without additional thermal analysis. Applications operating within -30°C to 85°C experience no temperature-related limitations.

Q: How do the connector types (Receptacle versus Plug) affect compatibility?

A: Both the original and substitute are female socket connectors designed for M12 circular connector systems. The original is a Receptacle configuration; the substitute is a Plug configuration. Compatibility depends on the mating connector type in the application. Verification that the system's complementary connector (male pin connector) is compatible with the substitute's Plug configuration is required.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Both parts are ROHS3 compliant and carry EAR99 export classification. Both maintain identical HTSUS commodity codes. The Amphenol substitute is REACH Unaffected, while the original is REACH Affected. For applications subject to REACH regulations, the substitute may offer regulatory advantages. Both parts carry Moisture Sensitivity Level 1 (Unlimited), eliminating moisture-related handling requirements.

Q: What is the inventory status of each part?

A: The original TE Connectivity 3-2172072-2 is classified as Obsolete with 944 pieces in stock. The Amphenol CONEC 43-01200 is Active with 1056 pieces in stock. For new designs and long-term supply assurance, the active Amphenol part is recommended.

Q: Are the solder termination specifications identical between the two parts?

A: Both parts use solder termination. Specific contact material and solder pad specifications are not provided in the available technical parameters. Verification of solder compatibility and PCB pad design with the substitute part's contact material specifications is recommended before implementation.
