Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902124 is determined by the following critical parameters:

• Current Rating: 32A (exact match required)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Mounting Type: DIN Rail (mechanical compatibility)
• Actuator Type: Lever (operational interface)
• Number of Poles: 1 (circuit configuration)

The identified substitute part 1019988 satisfies all core substitution criteria. This part maintains identical current rating, breaker topology, mounting configuration, and pole count. The substitute belongs to the active TMC 7 series and carries current RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019988 serves as the direct functional equivalent for the obsolete 0902124. Both components share identical current ratings, breaker topology, and mechanical mounting specifications. The substitute part carries active product status with current ROHS3 compliance certification, ensuring regulatory alignment and supply chain continuity.

The 1019988 provides specified voltage ratings (277 V AC, 60 V DC) not documented for the original part, offering enhanced technical clarity for system design verification.

Frequently Asked Questions (FAQ)

Q: Can the 1019988 directly replace the 0902124 in existing installations?

A: Yes. Both parts are 32A thermal-magnetic circuit breakers with identical DIN rail mounting, lever actuation, and single-pole configuration. The substitute maintains functional and mechanical compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1019988 is an active product with current manufacturing and supply availability. This ensures long-term component sourcing for maintenance and future installations, eliminating obsolescence-related supply constraints.

Q: How do the voltage ratings affect substitution suitability?

A: The 1019988 specifies 277 V AC and 60 V DC ratings. These ratings define the maximum operating voltages for the breaker. Substitution is appropriate when the application voltage does not exceed these specified limits.

Q: Are there packaging differences between these parts?

A: The 0902124 packaging is unspecified, while the 1019988 is supplied in box packaging. This difference does not affect functional compatibility or installation procedures.

Q: What compliance certifications apply to the substitute part?

A: The 1019988 carries ROHS3 compliance certification and is REACH unaffected, meeting current environmental and regulatory requirements for electronic components in industrial applications.
