Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2907673 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts 2907537 and 2907605 are classified as parametric equivalents because they maintain identical specifications in the following key areas:

• Current rating: 63A
• Voltage ratings: 240V AC and 125V DC
• Breaker type: Thermal Magnetic
• Number of poles: 2
• Actuator type: Lever
• Mounting configuration: DIN Rail
• Series family: TMC 8
• Packaging format: Box

All three parts are manufactured by Phoenix Contact and share the same functional classification within the TMC 8 product line. Substitution is valid only when these parameters remain unchanged in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status within the Phoenix Contact TMC 8 series and are classified as direct parametric equivalents. Selection between 2907673, 2907537, and 2907605 is based on compliance requirements and availability:

• 2907673: RoHS Compliant, 851 units in stock
• 2907537: RoHS Compliant, 1002 units in stock
• 2907605: ROHS3 Compliant with REACH Unaffected designation, 888 units in stock

Part 2907605 provides enhanced compliance documentation for applications requiring ROHS3 certification and REACH compliance verification. All parts share identical electrical performance and mechanical form factor, ensuring functional interchangeability in 63A, 240V AC / 125V DC circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can 2907537 or 2907605 be used as direct replacements for 2907673?

A: Yes. All three parts are parametric equivalents with identical current ratings (63A), voltage ratings (240V AC / 125V DC), pole configuration (2-pole), actuator type (lever), and DIN rail mounting. They are functionally interchangeable in the same circuit protection application.

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

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. Part 2907605 carries ROHS3 certification, while 2907673 and 2907537 carry RoHS Compliant designation. Selection depends on regulatory requirements for the end application.

Q: Are all three parts available in the same packaging format?

A: Yes. All parts are supplied in box packaging, ensuring consistent handling and storage requirements across substitution options.

Q: Does substitution affect circuit protection performance?

A: No. All three parts maintain identical thermal magnetic trip characteristics at 63A, ensuring equivalent protection performance in 240V AC / 125V DC circuits.

Q: What inventory levels are available for each part?

A: 2907673 has 851 units, 2907537 has 1002 units, and 2907605 has 888 units in stock as new original components.
