Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0902140 is determined by the following critical parameters:

• Breaker Type: Thermal Magnetic (required match)
• Current Rating: 50A (required match)
• Mounting Type: DIN Rail (required match)
• Actuator Type: Lever (required match)
• Number of Poles: 1 (required match)
• Manufacturer: Phoenix Contact (preferred for series continuity)

The substitute part Phoenix Contact 1019990 satisfies all mandatory electrical and mechanical parameters. This part belongs to the TMC 7 series, representing an active product line evolution from the obsolete TMC series, while maintaining identical functional specifications for the core switching and protection characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019990 is the direct substitute for the obsolete 0902140. Both components share identical core specifications: 50A thermal magnetic protection, lever actuation, single-pole configuration, and DIN rail mounting. The 1019990 is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute part provides enhanced compliance through ROHS3 certification and includes defined voltage ratings (277 V AC, 60 V DC) not explicitly stated in the original part specification. These voltage parameters are standard for this breaker class and do not restrict compatibility in applications previously served by the 0902140.

Inventory availability is confirmed for both parts, with 786 units of the 1019990 in stock, supporting immediate procurement for replacement and new installation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1019990 directly replace the 0902140 in existing installations?

A: Yes. Both parts are thermal magnetic 50A single-pole circuit breakers with lever actuation on DIN rail mounts. The mechanical and electrical interfaces are identical, allowing direct substitution without circuit redesign or panel modifications.

Q: What is the difference between the TMC and TMC 7 series?

A: The TMC 7 series represents the current production line for this breaker class. The 1019990 maintains functional equivalence to the obsolete TMC series while incorporating updated manufacturing standards and enhanced RoHS3 compliance.

Q: Are the voltage ratings of the 1019990 a limiting factor?

A: No. The 1019990 is rated for 277 V AC and 60 V DC, which covers standard industrial control voltage ranges. These ratings do not restrict application scope compared to the original part.

Q: What packaging is available for the 1019990?

A: The 1019990 is supplied in box packaging, suitable for standard component handling and storage in industrial environments.

Q: Is the 1019990 RoHS compliant?

A: Yes. The 1019990 meets ROHS3 compliance requirements, ensuring compatibility with current environmental and procurement standards.
