Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902108 is determined by the following critical parameters:

• Current Rating: 20A (exact match required)
• Breaker Type: Thermal Magnetic (functional protection mechanism)
• Mounting Type: DIN Rail (physical form factor)
• Actuator Type: Lever (manual operation interface)
• Number of Poles: 1 (single-pole configuration)
• Manufacturer: Phoenix Contact (series continuity)

The substitute part Phoenix Contact 1019985 satisfies all mandatory compatibility criteria. This part belongs to the TMC 7 series, representing an active product line evolution from the original TMC series, while maintaining identical electrical and mechanical specifications for the core protection function.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019985 is the direct substitute for the obsolete 0902108 based on the following factors:

Functional Equivalence: Both parts maintain identical current rating (20A), breaker type (thermal-magnetic), mounting configuration (DIN rail), and actuation method (lever). The single-pole configuration is preserved.

Compliance Status: The substitute part 1019985 carries active product status with ROHS3 compliance, representing current manufacturing standards. The original part's RoHS compliance is maintained and enhanced in the substitute.

Regulatory Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8536.20.0040) classifications, ensuring consistent export and tariff treatment.

Voltage Specifications: The substitute part provides explicit voltage ratings (277 V AC, 60 V DC), offering enhanced specification clarity compared to the original part documentation.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019985 directly replace the 0902108 in existing installations?
