Substitute Part Grouping Explanation

Substitution eligibility for the 104-P10-4A is determined by the following critical 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 Agency: CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 (all certifications must be present)
• RoHS Status: ROHS3 Compliant (exact match required)

The E-T-A 106-M2-P30-4A qualifies as a parametric equivalent because it matches all critical electrical and mechanical parameters while maintaining identical regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 104-P10-4A and 106-M2-P30-4A are Active status products from E-T-A with identical electrical specifications and regulatory certifications. Selection between these parts should be based on availability and inventory requirements. The 106-M2-P30-4A currently has higher inventory availability (1387 pcs vs 777 pcs). Both parts carry full compliance with CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 standards, and both are ROHS3 compliant with REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 106-M2-P30-4A be used as a direct replacement for the 104-P10-4A?

A: Yes. The 106-M2-P30-4A is a parametric equivalent with identical current rating (4A), voltage ratings (240V AC / 48V DC), breaker type (thermal), mounting configuration (panel mount), actuation method (push to reset), pole count (1), and all regulatory certifications.

Q: Are there any differences in physical dimensions or panel cutout requirements?

A: Physical dimensions and panel cutout specifications are not provided in the technical parameters. Mechanical compatibility must be verified against the specific panel mount application requirements.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 104-P10-4A and 106-M2-P30-4A carry identical approval agency certifications: CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

Q: What is the difference between the 104 and 106 series designations?

A: The series designation indicates different product lines within the E-T-A thermal circuit breaker portfolio. Both series meet the same electrical and regulatory requirements for this 4A, 240V AC / 48V DC application.

Q: Are both parts RoHS compliant?

A: Yes. Both the 104-P10-4A and 106-M2-P30-4A are ROHS3 compliant and REACH unaffected.
