Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902250 is determined by the following critical parameters:

• Current Rating: 20A (exact match required)
• Breaker Type: Thermal Magnetic (functional requirement)
• Number of Poles: 2 (circuit configuration requirement)
• Actuator Type: Lever (mechanical interface requirement)
• Mounting Type: DIN Rail (form factor requirement)
• Manufacturer: Phoenix Contact (product line continuity)

The substitute part Phoenix Contact 1020007 satisfies all mandatory parameters. This part is from the TMC 7 series, representing an active product line evolution within Phoenix Contact's thermal-magnetic breaker portfolio. Both parts maintain identical core electrical and mechanical specifications for the 20A, 2-pole, lever-actuated configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020007 is the appropriate substitute for the obsolete 0902250 based on the following factors:

Product Status: The 1020007 is an active product within Phoenix Contact's current portfolio, ensuring ongoing availability and supply chain continuity compared to the obsolete 0902250.

Compliance: Both parts are RoHS compliant. The 1020007 meets ROHS3 specifications and is REACH affected, reflecting current regulatory requirements. The 1020007 carries a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Electrical Specifications: The 1020007 provides explicit voltage ratings (277 V AC, 125 V DC) that define its operational envelope. These ratings should be cross-referenced with the original application requirements to confirm compatibility.

Functional Equivalence: Both parts maintain identical core specifications: 20A thermal-magnetic breaker, 2-pole configuration, lever actuator, and DIN rail mounting. This ensures mechanical and electrical interchangeability within the same application context.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020007 directly replace the 0902250 in existing installations?

A: Yes, provided the application voltage requirements align with the 1020007 specifications (277 V AC, 125 V DC). Both parts share identical current rating, pole configuration, actuator type, and mounting interface.

Q: What is the primary reason for substitution?
