Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1011962 are identified based on parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria include:

• Identical current rating (1A)
• Identical AC voltage rating (277V)
• Identical DC voltage rating (60V)
• Identical breaker type (Thermal Magnetic)
• Identical mounting configuration (DIN Rail)
• Identical actuator mechanism (Lever)
• Identical pole configuration (Single pole)
• Matching series designation (TMC 7)
• Equivalent environmental and compliance ratings

Parts 1019972 and 1020037 meet all parametric requirements for direct substitution with the main part number 1011962.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1011962, 1019972, and 1020037—are functionally equivalent and maintain active product status. Selection between these parts may be based on inventory availability and regulatory compliance requirements. Part 1011962 maintains ROHS3 compliance with REACH Unaffected status. Parts 1019972 and 1020037 maintain ROHS3 compliance with REACH Affected status. For applications requiring REACH Unaffected certification, part 1011962 is the specified selection. For general applications where REACH Affected status is acceptable, parts 1019972 and 1020037 provide equivalent functionality with higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can part 1019972 or 1020037 be used as a direct replacement for 1011962?

A: Yes. All three parts share identical electrical ratings (1A, 277V AC, 60V DC), breaker type (Thermal Magnetic), mounting configuration (DIN Rail), and actuator mechanism (Lever). They are parametrically equivalent and functionally interchangeable.

Q: What is the difference between these substitute parts?

A: The parts are electrically and mechanically identical. Differences exist only in REACH compliance status and inventory levels. Part 1011962 is REACH Unaffected, while parts 1019972 and 1020037 are REACH Affected.

Q: Are there any mechanical compatibility issues when substituting these parts?

A: No. All parts use identical DIN rail mounting, lever actuation, and single-pole configuration. Physical installation and electrical connection are identical across all three part numbers.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring REACH Unaffected certification, specify 1011962. For applications where REACH Affected status is acceptable, either 1019972 or 1020037 may be selected based on availability.

Q: Do these parts require any special handling or storage considerations?

A: All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
