Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1019946 is determined by strict equivalence across the following critical parameters:

• Current Rating: 32A
• Voltage Rating: 277V AC / 125V DC
• Breaker Type: Thermal Magnetic
• Mounting Configuration: DIN Rail, 2-pole
• Actuator Type: Lever
• Series Classification: TMC 7

Parts meeting all these criteria are classified as parametric equivalents and may be substituted without modification to circuit design or installation specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1019946 and 1020077 are active products with full compliance certifications. The 1020077 carries ROHS3 compliance status compared to the standard RoHS compliance of the 1019946, indicating alignment with current regulatory requirements. Both parts maintain identical electrical specifications, mechanical mounting configurations, and moisture sensitivity ratings. Selection between these equivalents may be based on inventory availability and compliance certification requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1020077 directly replace 1019946 in existing installations?

A: Yes. Both parts are parametric equivalents with identical current ratings (32A), voltage specifications (277V AC / 125V DC), mounting type (DIN Rail), pole configuration (2-pole), and actuator type (Lever). No circuit modifications or installation changes are required.

Q: What determines if a circuit breaker is a valid substitute for the 1019946?

A: A substitute must match all critical parameters: 32A current rating, 277V AC and 125V DC voltage ratings, thermal magnetic breaker type, DIN rail mounting, 2-pole configuration, and lever actuation. Deviation in any of these parameters disqualifies the part as a direct equivalent.

Q: Are there compliance differences between 1019946 and 1020077?

A: The 1020077 carries ROHS3 compliance certification, while the 1019946 carries standard RoHS compliance. Both are compliant products; the difference reflects regulatory classification updates. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the packaging format for these parts?

A: Both the 1019946 and 1020077 are supplied in box packaging, suitable for standard component storage and distribution.
