Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1019997 are identified based on strict parameter matching across all critical electrical and mechanical specifications. The substitution criteria include:

• Identical current rating (4A)
• Identical voltage ratings (277V AC and 125V DC)
• Identical breaker type (Thermal Magnetic)
• Identical mounting configuration (DIN Rail)
• Identical actuator mechanism (Lever)
• Identical pole configuration (2 poles)
• Matching compliance certifications (ROHS3, REACH unaffected)
• Same series classification (TMC 7)

Only parts meeting all these parameters are classified as direct equivalents. No functional or performance variations are permitted within this substitution group.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1019997 and 1019933 are active production components with identical electrical specifications and compliance certifications. Selection between these parts may be based on inventory availability, lead time, or supply chain requirements. Both components satisfy ROHS3 compliance and REACH regulatory requirements. The thermal magnetic protection characteristics, voltage ratings, and DIN rail mounting configuration are identical across both part numbers, ensuring functional interchangeability within the TMC 7 series.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1019933 be used as a direct replacement for 1019997?

A: Yes. Both parts share identical electrical ratings (4A, 277V AC / 125V DC), breaker type (thermal magnetic), mounting configuration (DIN rail), and compliance certifications. They are parametric equivalents within the TMC 7 series.

Q: Are there any differences in mechanical dimensions or mounting footprint?

A: The provided specifications confirm identical mounting type (DIN rail) and pole configuration (2 poles). No dimensional variations are indicated in the parametric data.

Q: Do both parts carry the same compliance certifications?

A: Yes. Both 1019997 and 1019933 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What determines substitution eligibility for this circuit breaker category?

A: Substitution is determined by matching current rating, voltage ratings (both AC and DC), breaker type, mounting method, actuator type, pole count, and compliance status. All parameters must align exactly.

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

A: Both parts are in active production status. Selection should be based on availability, supply chain logistics, and project requirements rather than technical preference.
