Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 105-P10-4A are identified based on parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based strictly on the following key parameters:

• Current Rating: 4A (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 48V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)
• Approval Agencies: CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The identified substitute parts (104-P10-4A and 106-M2-P30-4A) meet all these criteria and are therefore electrically and mechanically interchangeable with the main part number 105-P10-4A.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (105-P10-4A, 104-P10-4A, and 106-M2-P30-4A) maintain Active product status and carry identical international safety certifications. Selection between these interchangeable parts may be based on inventory availability and supply chain considerations. The 106-M2-P30-4A variant currently maintains the highest inventory level at 1387 pieces, while the 104-P10-4A and 105-P10-4A maintain 777 and 750 pieces respectively. All parts comply with ROHS3 requirements and carry EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can 104-P10-4A be used as a direct replacement for 105-P10-4A?

A: Yes. Both parts are parametrically equivalent thermal circuit breakers with identical electrical ratings (4A, 240V AC, 48V DC), mounting configuration (panel mount), and safety certifications. The difference lies only in the series designation (104 vs. 105).

Q: What is the difference between 105-P10-4A and 106-M2-P30-4A?

A: Both parts are electrically and mechanically equivalent with identical current ratings, voltage ratings, and certifications. The series designation differs (105 vs. 106), and the part number structure reflects different product lines within the E-T-A thermal breaker portfolio.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three substitute parts (105-P10-4A, 104-P10-4A, and 106-M2-P30-4A) are ROHS3 compliant and REACH unaffected.

Q: Do these parts carry the same safety certifications?

A: Yes. All three parts carry identical approval certifications: CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

Q: Can I mix these part numbers in the same application?

A: Yes. Since all three parts are parametrically equivalent across all critical electrical and mechanical specifications, they are interchangeable for applications requiring a 4A thermal circuit breaker with 240V AC / 48V DC ratings and panel mount configuration.
