Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2907639 is determined by strict parametric equivalence across the following critical specifications:

• Current Rating: 16A (exact match required)
• Voltage Rating AC: 277V (exact match required)
• Voltage Rating DC: 60V (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Number of Poles: 1 (exact match required)
• Actuator Type: Lever (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Series: TMC 8 (exact match required)

All identified substitute parts meet these parametric requirements and are manufactured by Phoenix Contact within the same product series. Substitutes are classified as parametric equivalents, indicating identical electrical and mechanical specifications suitable for direct replacement in applications requiring the 2907639.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—2907639, 2907491, and 2907572—are active Phoenix Contact products with identical electrical and mechanical specifications. Selection between these equivalents may be based on inventory availability and regulatory compliance status.

Part 2907639 and 2907491 carry REACH Affected designation, while part 2907572 is REACH Unaffected. For applications subject to REACH compliance requirements, part 2907572 may be the preferred selection. All parts maintain ROHS3 compliance and EAR99 export classification.

Current inventory levels are: 2907639 (697 pcs), 2907491 (1212 pcs), and 2907572 (715 pcs). Procurement decisions should account for supply availability and project-specific regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can part 2907491 be used as a direct replacement for 2907639?

A: Yes. Part 2907491 is a parametric equivalent with identical current rating (16A), voltage ratings (277V AC / 60V DC), breaker type (thermal magnetic), pole configuration (1-pole), actuator type (lever), and DIN rail mounting. Both parts are active Phoenix Contact TMC 8 series products with ROHS3 compliance.

Q: What is the difference between 2907572 and the other two part numbers?

A: Part 2907572 is electrically and mechanically identical to 2907639 and 2907491. The primary distinction is REACH compliance status: 2907572 is REACH Unaffected, while 2907639 and 2907491 are REACH Affected. All other specifications, including current rating, voltage ratings, breaker type, and mounting configuration, are identical.

Q: Are these parts interchangeable in existing installations?

A: Yes. All three part numbers share identical electrical ratings (16A, 277V AC, 60V DC), mechanical configuration (1-pole, lever-actuated, DIN rail mount), and thermal magnetic protection characteristics. They are direct functional equivalents suitable for replacement applications.

Q: Does REACH compliance status affect part selection?

A: REACH compliance status may be relevant for applications in European Union markets or for organizations with specific regulatory requirements. Part 2907572 (REACH Unaffected) may be preferred in such contexts. For applications without REACH-specific requirements, all three parts are equivalent.

Q: What packaging format is used for these circuit breakers?

A: All three part numbers are supplied in box packaging, consistent with standard Phoenix Contact distribution for DIN rail-mounted circuit breakers.
