Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902221 is determined by the following critical parameters:

• Current Rating: 10A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 2 (exact match required)
• Actuator Type: Lever (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Manufacturer: Phoenix Contact (same manufacturer preferred for series compatibility)

The substitute part Phoenix Contact 1020002 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. Both components share identical core specifications for current rating, pole configuration, actuation method, and mounting standard.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1020002 serves as the direct functional equivalent for the obsolete 0902221. Both components maintain identical specifications for current rating, pole count, actuation mechanism, and DIN rail mounting compatibility.

The 1020002 is classified as an active product with current manufacturing support and significantly higher inventory availability (30,400 units in stock versus 694 units for the obsolete part). This substitute carries ROHS3 compliance, representing current regulatory standards, and includes specified voltage ratings of 277V AC and 125V DC.

Selection of the 1020002 is supported by product status alignment (active versus obsolete), enhanced compliance certification, and established supply chain availability. Both components are manufactured by Phoenix Contact, ensuring series compatibility and mechanical interchangeability within DIN rail installations.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1020002 directly replace the 0902221 in existing installations?
