Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0902111 is determined by the following critical parameters:

• Current Rating: 25A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 1 (exact match required)
• Manufacturer: Phoenix Contact (same manufacturer preferred for consistency)

The substitute part Phoenix Contact 1019986 satisfies all mandatory electrical and mechanical parameters. The primary distinction is the active product status of the substitute, combined with specified voltage ratings and enhanced moisture sensitivity classification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1019986 is the qualified substitute for the obsolete 0902111 based on the following criteria:

Electrical Compatibility: Both components share identical current rating (25A), breaker type (thermal-magnetic), pole configuration (1-pole), and actuator mechanism (lever). The substitute provides explicit voltage ratings of 277 V AC and 60 V DC, establishing defined operating parameters.

Mechanical Compatibility: Both components utilize identical DIN rail mounting and lever actuation, ensuring physical interchangeability within existing installations.

Regulatory Compliance: Both components maintain ROHS3 compliance. The substitute carries REACH Affected status, indicating full regulatory documentation availability. The substitute's moisture sensitivity classification (MSL 1 - Unlimited) reflects current manufacturing standards.

Product Status: The substitute's active product status ensures ongoing availability, technical support, and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019986 directly replace the 0902111 in existing installations?

A: Yes. Both components share identical current rating (25A), thermal-magnetic breaker type, 1-pole configuration, lever actuation, and DIN rail mounting. Physical and electrical interchangeability is established.

Q: What is the significance of the voltage ratings specified for the 1019986?

A: The substitute provides explicit voltage ratings (277 V AC, 60 V DC) that define its operational envelope. These ratings should be verified against your system voltage requirements to ensure compatibility.

Q: Does the change in series designation (TMC to TMC 7) affect substitution validity?

A: No. Series designation reflects product line evolution. The critical parameters determining substitution eligibility—current rating, breaker type, mounting, actuation, and pole count—remain identical between both components.

Q: What does the Moisture Sensitivity Level (MSL 1) indicate for the substitute?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions during storage or handling, reflecting standard manufacturing practices for this component category.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is unspecified. The substitute is supplied in box packaging. Verify packaging requirements for your procurement and logistics processes.
