Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2907502 is determined by strict equivalence across the following parameters: identical current rating (1A), matching voltage ratings (480V AC / 125V DC), same breaker type (thermal magnetic), identical mounting configuration (DIN rail), matching actuator type (lever), and equivalent pole count (2). All substitute parts listed maintain these core electrical and mechanical specifications without deviation. Compliance certifications and inventory status are secondary factors that do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—2907502, 2907582, and 2907650—are functionally equivalent for applications requiring a 1A thermal magnetic circuit breaker at 480V AC / 125V DC with DIN rail mounting. Selection between these parts should be based on availability and compliance requirements specific to the end application. Parts 2907582 and 2907650 carry ROHS3 certification, which may be required for certain regulated markets or customer specifications. The 2907502 maintains standard RoHS compliance. All parts share identical electrical ratings, mechanical configuration, and export classification (EAR99), ensuring direct substitution without circuit redesign or application re-qualification.

Frequently Asked Questions (FAQ)

Q: Can part 2907582 replace part 2907502 in an existing installation? A: Yes. Both parts are parametrically equivalent across all critical specifications: 1A current rating, 480V AC / 125V DC voltage ratings, thermal magnetic operation, DIN rail mounting, lever actuation, and two-pole configuration. No circuit modifications are required.

Q: What is the difference between RoHS and ROHS3 compliance on these parts? A: RoHS and ROHS3 represent different regulatory compliance frameworks. Both certifications indicate restriction of hazardous substances, but ROHS3 reflects updated compliance standards. Selection depends on customer or regional requirements. All three parts meet their respective compliance designations.

Q: Are these parts interchangeable in terms of physical dimensions? A: Yes. All three parts share identical mounting type (DIN rail), actuator type (lever), and pole count (2), ensuring mechanical interchangeability within DIN rail enclosures.

Q: Does MSL (Moisture Sensitivity Level) affect substitution eligibility? A: MSL ratings apply to storage and handling conditions, not functional performance. Part 2907582 carries MSL 1 (Unlimited), while 2907502 and 2907650 are marked as Not Applicable. This does not affect electrical interchangeability but may influence logistics and storage protocols.

Q: Can I use part 2907650 as a direct substitute if my application specifies part 2907502? A: Yes, provided your application does not contain specific part number lock-in requirements. All three parts meet identical electrical and mechanical specifications for 1A, 480V AC / 125V DC thermal magnetic circuit breaker operation.
