Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5651396 is determined by matching the following critical parameters:

• Current Rating: 5A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Breaker Type: Thermal Magnetic
• Mounting Type: DIN Rail
• Actuator Type: Push to Reset
• Number of Poles: 2
• RoHS Compliance: Required

The Weidmüller 7940126723 satisfies all substitution criteria, sharing identical electrical ratings, mechanical configuration, and compliance status. Both parts function as two-pole thermal magnetic circuit breakers with equivalent protection characteristics and mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 5651396 and Weidmüller 7940126723 are active products with RoHS compliance. The Weidmüller part carries additional certifications including CSA C22.2 No 235, UL1077, and VDE approval, providing expanded regulatory coverage. Selection between these parts should be based on supply availability, lead time requirements, and specific regional certification needs. The Weidmüller 7940126723 offers broader approval agency recognition, which may be advantageous in applications requiring multi-standard compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 7940126723 directly replace the Phoenix Contact 5651396?

A: Yes. Both parts share identical current ratings (5A), voltage ratings (250V AC / 80V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), actuation method (push to reset), pole count (2), and RoHS compliance status. Direct substitution is supported for applications requiring these specifications.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by current rating, AC and DC voltage ratings, breaker type, mounting type, actuator type, number of poles, and RoHS compliance. All these parameters must match between the original and substitute part.

Q: Are there differences in certifications between these parts?

A: The Weidmüller 7940126723 includes CSA C22.2 No 235, UL1077, and VDE certifications. The Phoenix Contact 5651396 specifications do not list these certifications. Applications requiring specific regional approvals should verify certification alignment with local requirements.

Q: What is the difference between the TMC and CB4200 series designations?

A: TMC is the Phoenix Contact series designation, while CB4200 is the Weidmüller series designation. These are manufacturer-specific series identifiers and do not affect electrical or mechanical compatibility between the parts.

Q: Are both parts currently available?

A: Both parts maintain active product status. Inventory availability should be verified with component suppliers, as stock levels vary by distributor and region.
