• Voltage Rating - AC: 240V
• Voltage Rating - DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Rocker
• Number of Poles: 3
• Series: IUG

The IUGX666-1-42-10.0-21 meets all electrical and mechanical substitution criteria. This part maintains identical functional specifications while differing in product status classification.

Parameter Comparison

Engineering Selection Recommendations

The IUGX666-1-42-10.0-21 qualifies as a parametric equivalent to the IUGZX666-1-42-10.0-21 based on identical electrical ratings, mechanical configuration, and protection characteristics. Both parts are RoHS Compliant and carry MSL 1 classification.

The primary distinction is product status: the main part is Active, while the substitute is classified as Obsolete. Selection between these parts should be based on supply chain requirements and long-term availability considerations. Both parts maintain equivalent functional performance and compliance certifications.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the IUGZX666-1-42-10.0-21?

A: A substitute must match all critical electrical parameters (10A current rating, 240V AC / 80V DC voltage ratings), protection mechanism (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), actuator type (Rocker), and pole count (3). The IUGX666-1-42-10.0-21 satisfies these requirements.

Q: How does product status affect substitution eligibility?

A: Product status does not disqualify a part from functional substitution. The Obsolete classification indicates discontinued production; however, the IUGX666-1-42-10.0-21 remains electrically and mechanically equivalent. Inventory availability and supply chain continuity should guide selection decisions.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts share identical mounting type (Panel Mount), actuator configuration (Rocker), and pole arrangement (3-pole). Physical installation and electrical connection are fully compatible.

Q: What is the significance of RoHS Compliance for both parts?

A: Both the IUGZX666-1-42-10.0-21 and IUGX666-1-42-10.0-21 are RoHS Compliant, confirming compliance with hazardous substance restrictions. This certification applies equally to both parts and does not differentiate substitution eligibility.

Q: Does Moisture Sensitivity Level affect substitution?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Storage, handling, and operational conditions are equivalent for both components.
