Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IAGN666-1-66-30.0-A are qualified based on identical electrical and mechanical parameters. The following criteria determine substitution eligibility:

• Current Rating: 30A (exact match required)
• Voltage Rating – AC: 250 V (exact match required)
• Voltage Rating – DC: 80 V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
• Number of Poles: 3 (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Toggle (exact match required)
• RoHS Status: RoHS Compliant (exact match required)

The substitute parts IUGN666-1REC4-52-50.0 and IUGN666-1REC4-53-50.0 meet all specified electrical and mechanical parameters and are therefore functionally equivalent for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts IUGN666-1REC4-52-50.0 and IUGN666-1REC4-53-50.0 are active products with RoHS compliance matching the original IAGN666-1-66-30.0-A. All three parts share identical electrical ratings, mechanical configuration, and regulatory compliance status. Selection between the main part and substitutes may be based on inventory availability and lead time requirements. IUGN666-1REC4-52-50.0 has 1044 units in stock, while IUGN666-1REC4-53-50.0 has 883 units available.

Frequently Asked Questions (FAQ)

Q: Can IUGN666-1REC4-52-50.0 or IUGN666-1REC4-53-50.0 be used as direct replacements for IAGN666-1-66-30.0-A?

A: Yes. Both substitute parts meet all specified electrical parameters (30A, 250V AC, 80V DC), mechanical configuration (3-pole, toggle actuator, panel mount), and regulatory requirements (RoHS compliant). They are functionally equivalent for direct replacement.

Q: What is the difference between the two substitute parts?

A: IUGN666-1REC4-52-50.0 and IUGN666-1REC4-53-50.0 share identical electrical and mechanical specifications. Both are from the IUG series and meet all substitution criteria. Differences, if any, are not specified in the provided parameters.

Q: Are all three parts packaged identically?

A: Yes. The main part and both substitutes are supplied in bulk packaging.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. All three parts are RoHS compliant with MSL rating of 1 (Unlimited) and carry the same ECCN (EAR99) and HTSUS (8536.20.0020) classifications.

Q: What factors should determine which part to select?

A: Since all three parts are electrically and mechanically equivalent, selection should be based on inventory availability and procurement lead time. IUGN666-1REC4-52-50.0 and IUGN666-1REC4-53-50.0 offer alternative sourcing options within the same specification range.
