Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 2907603 are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

• Current Rating: 50A (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 125V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 2 (exact match required)
• Actuator Type: Lever (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Series: TMC 8 (exact match required)
• Manufacturer: Phoenix Contact (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—2907603, 2907535, and 2907671—are functionally equivalent thermal magnetic circuit breakers within the Phoenix Contact TMC 8 series. Selection between these parts is based on availability and inventory status rather than electrical or mechanical performance differences. All parts maintain active product status and full ROHS3 compliance, ensuring regulatory conformance in current and future applications. The choice among these equivalents does not affect circuit protection characteristics, mounting compatibility, or operational performance.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2907535 be used as a direct replacement for 2907603?

A: Yes. Both parts are parametrically equivalent with identical current ratings (50A), voltage ratings (240V AC / 125V DC), breaker type (thermal magnetic), pole configuration (2-pole), actuator type (lever), and DIN rail mounting. No circuit modifications are required.

Q: Are there any differences in performance between 2907603, 2907535, and 2907671?

A: No. All three parts share identical electrical specifications, mechanical design, and compliance certifications. Performance characteristics are equivalent across all parameters.

Q: What is the difference between these part numbers if they are equivalent?

A: The part numbers represent different manufacturing batches or internal Phoenix Contact product variants within the same specification class. The differences are administrative rather than technical.

Q: Can these breakers be mixed in the same installation?

A: Yes. Since all three parts are parametrically identical, they can be used interchangeably within the same circuit or system without affecting performance or safety.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—2907603, 2907535, and 2907671—carry ROHS3 compliance certification.

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory status. Phoenix Contact 2907535 has the highest inventory (1125 pcs), followed by 2907603 (916 pcs) and 2907671 (794 pcs). All are listed as new original stock.
