Substitute Part Grouping Explanation

Substitute parts for the IUGN6-1-66-20.0 are identified based on strict parametric equivalence within the IUG series. The substitution criteria are limited to the following electrical and mechanical parameters:

• Current Rating: 10A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Toggle
• Number of Poles: 1
• Series: IUG

Parts meeting all of these criteria are classified as parametric equivalents and may be substituted in applications where the main part number is specified, subject to packaging and inventory availability considerations.

Parameter Comparison

Engineering Selection Recommendations

Both the IUGN6-1-66-20.0 and IUGN6-1-42-15.0 are active production components manufactured by Sensata-Airpax within the IUG series. Both parts are RoHS compliant and carry identical electrical ratings, mechanical specifications, and regulatory classifications. Selection between these parts may be based on packaging format availability (the main part is available in standard packaging, while the substitute is available in bulk packaging) and current inventory levels. Both parts satisfy identical functional and compliance requirements for panel-mount circuit breaker applications.

Frequently Asked Questions (FAQ)

Q: Can IUGN6-1-42-15.0 be used as a direct replacement for IUGN6-1-66-20.0?

A: Yes. Both parts share identical electrical ratings (10A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount toggle), and regulatory compliance status. The parts are parametric equivalents within the IUG series.

Q: What is the difference between these two part numbers?

A: The part numbers differ in their internal designation codes. The electrical and mechanical performance characteristics are identical. The primary operational difference is packaging format: IUGN6-1-66-20.0 is supplied in standard packaging, while IUGN6-1-42-15.0 is supplied in bulk packaging.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist for applications where the electrical and mechanical parameters are the controlling factors. Both parts are single-pole toggle-actuated panel-mount circuit breakers with identical voltage and current ratings.

Q: What certifications apply to both parts?

A: Both parts are RoHS compliant, carry MSL rating of 1 (Unlimited), and are classified under ECCN EAR99 and HTSUS 8536.20.0020.
