Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 0914947 qualifies as a direct substitute for the 0902166 based on the following critical parameters:

• Current Rating: Both parts are rated at 500mA
• Breaker Type: Both employ thermal-magnetic protection
• Number of Poles: Both are configured as 2-pole devices
• Actuator Type: Both feature lever actuation
• Mounting Type: Both mount on DIN rail
• Series: Both belong to the TMC series
• Product Status: The 0914947 is active, providing continued availability

The 0914947 introduces specified voltage ratings (250V AC, 65V DC) not documented in the original 0902166 specification, representing an enhancement in application clarity while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 0914947 is the appropriate substitute for the obsolete 0902166. Both components share identical electrical ratings (500mA), mechanical configuration (2-pole, lever-actuated), and mounting interface (DIN rail). The 0914947 maintains RoHS compliance through ROHS3 certification and is currently in active production status, ensuring supply chain continuity.

Selection of the 0914947 is based on functional equivalence across all specified parameters and active product availability. The addition of explicit voltage ratings in the 0914947 specification provides enhanced clarity for circuit design without altering the component's core protective function.

Frequently Asked Questions (FAQ)

Q: Can the 0914947 directly replace the 0902166 in existing installations?

A: Yes. Both components share identical current ratings (500mA), pole configuration (2-pole), actuator type (lever), and DIN rail mounting. The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the voltage ratings specified for the 0914947?

A: The 0914947 documentation includes explicit voltage ratings (250V AC, 65V DC) that define the maximum operating voltages for the device. These ratings establish the safe operating envelope for the circuit breaker and should be verified against your application requirements.

Q: Why is the 0902166 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 0914947 represents the current Phoenix Contact offering within the TMC series at the 500mA rating and should be used for new designs and ongoing procurement.

Q: Are there packaging differences between these parts?

A: The 0902166 packaging is listed as unspecified, while the 0914947 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet current regulatory compliance standards?

A: The 0902166 is RoHS Compliant. The 0914947 meets ROHS3 Compliant standards, representing current regulatory alignment. The 0914947 is also REACH Affected, indicating compliance with additional European chemical regulations.
