Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 5650122 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

  • Current Rating: 12A (exact match required)
  • Voltage Rating - AC: 250V (exact match required)
  • Voltage Rating - DC: 80V (exact match required)
  • Breaker Type: Thermal Magnetic (exact match required)
  • Mounting Type: DIN Rail (exact match required)
  • Actuator Type: Push to Reset (exact match required)
  • Number of Poles: 1 (exact match required)

The Weidmüller part 7940125378 meets all critical electrical and mechanical parameters, making it a parametric equivalent suitable for direct substitution in applications requiring identical performance characteristics.

Engineering Selection Recommendations

Both the Phoenix Contact 5650122 and Weidmüller 7940125378 are active products with full RoHS compliance. The Weidmüller part carries additional regulatory approvals including CSA C22.2 No 235, UL1077, and VDE certification. Selection between these parts should be based on:

  • Supply availability and lead time requirements
  • Existing supplier relationships and procurement processes
  • Regulatory approval requirements specific to the application
  • Inventory management and cost considerations

Both parts are electrically and mechanically interchangeable for applications requiring a 12A, 250V AC / 80V DC thermal magnetic circuit breaker with DIN rail mounting and push-to-reset actuation.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 7940125378 directly replace the Phoenix Contact 5650122?

A: Yes. Both parts share identical electrical ratings (12A, 250V AC, 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and actuation method (push to reset). They are parametric equivalents suitable for direct substitution.

Q: What parameters must match for a circuit breaker to be considered a substitute?

A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, and pole count must all match exactly. Any deviation in these parameters disqualifies a part from substitution.

Q: Are there differences in regulatory approvals between these parts?

A: The Weidmüller 7940125378 carries CSA C22.2 No 235, UL1077, and VDE approvals. The Phoenix Contact 5650122 specifications do not list these approvals in the provided data. Verify approval requirements for your specific application before selection.

Q: What is the difference between the ECCN and HTSUS codes?

A: ECCN (Export Control Classification Number) and HTSUS (Harmonized Tariff Schedule of the United States) are trade classification codes. The Phoenix Contact part is classified as 5A991B1 (ECCN) and 8536.20.0020 (HTSUS), while the Weidmüller part is classified as EAR99 (ECCN) and 8538.90.8120 (HTSUS). These classifications may affect export and import procedures.

Q: Is RoHS compliance the same for both parts?

A: Yes. Both the Phoenix Contact 5650122 and Weidmüller 7940125378 are RoHS compliant and have MSL (Moisture Sensitivity Level) marked as Not Applicable.
