Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 0902137 is determined by the following critical parameters:

• Current Rating: 40A (exact match required)
• Breaker Type: Thermal Magnetic (functional equivalence)
• Actuator Type: Lever (mechanical interface requirement)
• Number of Poles: 1 (circuit configuration)
• Mounting Type: DIN Rail (form factor requirement)
• Manufacturer: Phoenix Contact (series continuity)

The substitute part Phoenix Contact 1019989 satisfies all mandatory substitution criteria. This part belongs to the TMC 7 series, representing an active product line evolution from the obsolete TMC series. Both components share identical current ratings, breaker topology, actuation mechanism, pole configuration, and mounting standard, establishing direct functional equivalence.

Engineering Selection Recommendations

The Phoenix Contact 1019989 serves as the direct substitute for the obsolete 0902137. Selection is justified on the following basis:

• Product Status Alignment: The 1019989 is an active product, ensuring long-term availability and supply chain continuity compared to the obsolete 0902137.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification to system design.
• Functional Equivalence: Identical current rating (40A), breaker topology (thermal-magnetic), actuation mechanism (lever), pole configuration (1-pole), and mounting standard (DIN rail) establish direct functional interchangeability.
• Series Evolution: The 1019989 represents the active TMC 7 series continuation, indicating manufacturer support and design validation for modern applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1019989 directly replace the 0902137 in existing installations?

A: Yes. Both components share identical current ratings (40A), thermal-magnetic breaker topology, lever actuation, single-pole configuration, and DIN rail mounting. The 1019989 is mechanically and functionally equivalent for direct substitution.

Q: What is the primary reason for substitution?

A: The 0902137 is classified as obsolete. The 1019989 is an active product from the TMC 7 series, ensuring availability and manufacturer support.

Q: Are there voltage rating differences between these parts?

A: The 0902137 does not specify voltage ratings in the provided data. The 1019989 is rated for 277 V AC and 60 V DC. Voltage compatibility must be verified against the application circuit requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0902137 and 1019989 are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and regulatory requirements.

Q: What is the packaging difference?

A: The 0902137 packaging is not specified. The 1019989 is supplied in box packaging. This does not affect functional performance or installation compatibility.

Q: Are there inventory considerations?

A: The 0902137 has 808 pieces in stock (obsolete status). The 1019989 has 673 pieces in stock (active status). For new designs or long-term requirements, the 1019989 is recommended due to active product status.
