Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical and mechanical parameters with the main part 0914439. Substitution eligibility is determined by the following criteria:

• Current Rating: 1A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 65V (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)
• Series: TMC (exact match required)
• Product Status: Active (exact match required)

The substitute parts 0914073, 0914251, and 0914617 satisfy all these criteria and are therefore direct parametric equivalents suitable for interchangeable use in applications requiring a 1A thermal magnetic circuit breaker with 250V AC and 65V DC ratings on DIN rail.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers are active products from Phoenix Contact with confirmed inventory availability. Selection between 0914439, 0914073, 0914251, and 0914617 may be based on the following compliance and certification considerations:

For applications requiring ROHS3 compliance with REACH certification, parts 0914439, 0914073, and 0914617 are suitable. Part 0914251 carries RoHS compliance without specified REACH status and may be selected where REACH certification is not a requirement.

Inventory availability ranges from 747 to 1064 pieces across all four part numbers, supporting procurement decisions based on supply chain requirements and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can part 0914251 be used as a direct substitute for 0914439?

A: Yes. Part 0914251 is a parametric equivalent with identical electrical ratings (1A, 250V AC, 65V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and actuator design (lever). The primary difference is RoHS certification level; 0914251 carries RoHS compliance while 0914439 carries ROHS3 compliance. Selection depends on regulatory requirements for your application.

Q: What are the critical parameters that determine substitutability?

A: Substitutability is determined by exact matching of current rating (1A), AC voltage (250V), DC voltage (65V), breaker type (thermal magnetic), mounting type (DIN rail), actuator type (lever), pole count (1), and series designation (TMC). All listed substitutes meet these criteria.

Q: Are there differences in REACH or RoHS compliance between these parts?

A: Parts 0914439, 0914073, and 0914617 carry ROHS3 compliance with REACH certification. Part 0914251 carries RoHS compliance without specified REACH status. Verify compliance requirements for your specific application before selection.

Q: Can these parts be mixed in the same installation?

A: Yes. All four parts are mechanically and electrically identical within the specified parameters and are suitable for use in the same DIN rail installation. Compliance certifications should be verified against application requirements.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents the current Restriction of Hazardous Substances directive implementation. RoHS compliance indicates adherence to the directive but may reference an earlier version. Confirm your application's specific compliance requirements.
