Substitute Part Grouping Explanation

Substitute parts for the IUGN66-0-SW-50.0 are identified based on electrical and mechanical parameter equivalence within the IUG series. The substitution criteria are strictly limited to the following parameters:

• Current Rating: 2.5A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Number of Poles: 1
• Actuator Type: Toggle
• Mounting Type: Panel Mount
• RoHS Status: RoHS Compliant

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications requiring the specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the IUGN66-0-SW-50.0 and IUGN6-1-65-10.0 are Active status products manufactured by Sensata-Airpax and carry RoHS Compliant certification. Selection between these parts should be based on availability and procurement lead times, as both meet identical electrical and mechanical specifications. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can IUGN6-1-65-10.0 be used as a direct replacement for IUGN66-0-SW-50.0?

A: Yes. Both parts are parametric equivalents with identical current ratings (2.5A), voltage ratings (250V AC / 80V DC), breaker type (Magnetic Hydraulic Delay), pole configuration (1-pole), actuator type (Toggle), and mounting type (Panel Mount). They are interchangeable in applications requiring these specifications.

Q: Are there any differences in RoHS compliance or moisture sensitivity between these parts?

A: No. Both parts are RoHS Compliant and carry MSL 1 (Unlimited) rating, indicating identical environmental compliance and handling requirements.

Q: What parameters determine substitution eligibility for IUG series circuit breakers?

A: Substitution eligibility is determined by matching current rating, AC and DC voltage ratings, breaker type, number of poles, actuator type, and mounting type. All these parameters must align for parts to be considered equivalent.

Q: Are both parts suitable for new production designs?

A: Yes. Both parts carry Active product status, indicating they are supported for current and future production applications.
