Phoenix Contact 1020073 Circuit Breaker 16A Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1020073 is a thermal magnetic circuit breaker rated for 16A with dual voltage capability (277V AC / 125V DC). This DIN rail-mounted device features a lever actuator and is part of the TMC 7 series. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Equivalent substitute parts are necessary to ensure supply chain continuity, support inventory optimization, and provide alternative sourcing options when the primary part number becomes unavailable or when procurement lead times require parallel sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1020073 is determined by strict equivalence across the following critical parameters: thermal magnetic breaker type, 16A current rating, dual voltage operation (277V AC and 125V DC), 2-pole configuration, lever actuator, DIN rail mounting, and TMC 7 series classification. All substitute parts listed maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability without circuit redesign or installation modification. Substitutes are grouped as parametric equivalents, meaning they satisfy all specified performance and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1020073, 1019942, and 1020006—are functionally equivalent and interchangeable for applications requiring a 16A thermal magnetic circuit breaker with 277V AC / 125V DC dual voltage operation on DIN rail installations. Selection between these equivalents should be based on procurement availability, inventory levels, and lead time requirements. All parts maintain active product status, ROHS3 compliance, and REACH unaffected certification, ensuring regulatory and environmental compliance across all substitution options. No technical performance differentiation exists between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can part numbers 1019942 and 1020006 be used interchangeably with 1020073 in existing installations?

A: Yes. All three part numbers are parametric equivalents with identical electrical ratings (16A, 277V AC / 125V DC), mechanical configuration (2-pole, lever actuator, DIN rail mount), and breaker type (thermal magnetic). Direct substitution requires no circuit modification or installation changes.

Q: What determines whether a circuit breaker qualifies as a substitute for the 1020073?

A: Substitution eligibility requires matching specifications across current rating (16A), voltage ratings (277V AC and 125V DC), breaker type (thermal magnetic), pole count (2), actuator type (lever), mounting method (DIN rail), and series classification (TMC 7). Deviation in any of these parameters disqualifies a part from substitution.

Q: Are there inventory or lead time advantages to selecting one substitute over another?

A: Inventory levels differ among the three equivalents: 1020073 has 821 units in stock, 1019942 has 1092 units, and 1020006 has 670 units. Selection based on current inventory availability may optimize procurement timelines and reduce supply chain delays.

Q: Do all substitute parts carry the same compliance certifications?

A: Yes. All three part numbers are ROHS3 compliant and REACH unaffected, ensuring identical regulatory and environmental compliance status across all substitution options.

Q: Is there a preferred part number for new designs?

A: No technical preference exists. All three part numbers are active products within the TMC 7 series. Design selection should be based on supplier availability, inventory status, and organizational procurement policies.
