Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2907658 is determined by exact matching of the following critical parameters: current rating (8A), AC voltage rating (480V), DC voltage rating (125V), breaker type (thermal magnetic), mounting configuration (DIN rail), actuator mechanism (lever), and pole count (2). The substitute part 2907510 meets all these requirements, establishing it as a parametric equivalent within the TMC 8 series. Both parts maintain identical electrical performance characteristics and mechanical interface specifications, enabling direct replacement without circuit redesign or installation modification.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 2907658 and 2907510 are active products with identical regulatory compliance profiles. Selection between these parts should be based on inventory availability and procurement lead times. The 2907658 maintains 1125 units in current stock, while the 2907510 has 769 units available. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial control applications. The parametric equivalence of these components permits interchangeable use in 8A, 480V AC / 125V DC circuit protection applications requiring DIN rail thermal magnetic protection with lever actuation.

Frequently Asked Questions (FAQ)

Q: Can the 2907510 directly replace the 2907658 in an existing installation? A: Yes. Both parts are parametric equivalents with identical current ratings (8A), voltage ratings (480V AC / 125V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and actuator mechanism (lever). Direct substitution is permissible without circuit modification.

Q: What parameters must match for substitution eligibility? A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, and pole count must all be identical. The 2907510 matches all these specifications for the 2907658.

Q: Are there compliance differences between these parts? A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and active product status. Regulatory requirements are equivalent.

Q: Does packaging affect substitution? A: Both parts are supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the primary reason to consider the 2907510 as an alternative? A: Inventory availability and procurement optimization. When the primary part number faces supply constraints, the 2907510 provides an equivalent solution with identical performance characteristics.
