Substitute Part Grouping Explanation

Substitution eligibility for the 104-P30-2A is determined by strict equivalence across the following critical parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 48V (exact match required)
• Breaker Type: Thermal (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Approval Agencies: CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 (all certifications must be present)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 104-PR-2A meets all these criteria and is classified as a parametric equivalent within the E-T-A 104 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 104-P30-2A and 104-PR-2A are Active status products manufactured by E-T-A within the 104 series. Selection between these parts should be based on availability and procurement lead times, as they are parametric equivalents with identical electrical and mechanical specifications. Both parts carry full compliance to CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 certifications, and both are ROHS3 compliant. The 104-PR-2A currently maintains higher inventory availability at 850 pieces compared to 999 pieces for the 104-P30-2A, making it suitable for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the 104-PR-2A be used as a direct replacement for the 104-P30-2A?

A: Yes. The 104-PR-2A is a parametric equivalent with identical current rating (2A), voltage ratings (240V AC / 48V DC), breaker type (thermal), actuator type (push to reset), mounting configuration (through hole), and all required certifications. Direct substitution is permissible in applications where the 104-P30-2A is specified.

Q: Are there any differences in physical dimensions or package footprint between these parts?

A: No dimension or package data was provided in the technical specifications. Both parts share identical mounting type (through hole) and series designation (104). Physical compatibility should be confirmed through mechanical drawings if required for your specific application.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 104-P30-2A and 104-PR-2A carry identical approval certifications: CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the part numbers 104-P30-2A and 104-PR-2A?

A: The part numbers differ in their internal designation codes (P30 versus PR), but this reflects internal E-T-A product line organization. From an electrical and mechanical standpoint, both parts are functionally identical and belong to the same 104 series thermal circuit breaker family.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on supplier availability, lead time, and inventory status. Both parts are Active status products with full compliance documentation.
