Substitute Part Grouping Explanation

Substitution of the ROV20-361K is determined by strict equivalence across the following electrical and mechanical parameters:

Varistor voltage rating (324V minimum to 396V maximum range)
Surge current capacity (6.5 kA)
Maximum AC and DC voltage specifications (230V AC, 300V DC)
Through-hole mounting configuration with disc 20mm package geometry
Single circuit configuration
RoHS3 compliance status

The V230LA40AP meets all these criteria and is manufacturer-recommended as a direct substitute.

The V230LA40AP carries active product status, ensuring ongoing availability and supply chain continuity. The substitute is available in bulk packaging with 2785 units in stock, compared to 1106 units of the obsolete ROV20-361K.

Frequently Asked Questions (FAQ)

Q: Can the V230LA40AP directly replace the ROV20-361K in existing applications?

A: Yes. Both components share identical electrical ratings (360V typical varistor voltage, 6.5kA surge current, 230V AC / 300V DC maximum ratings) and identical through-hole disc 20mm packaging. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The ROV20-361K is classified as obsolete. The V230LA40AP is the active equivalent from the same manufacturer, providing identical performance with assured long-term availability.

Q: Are there differences in energy dissipation between these parts?

A: The ROV20-361K specifies 208J energy dissipation, while the V230LA40AP specifies 122J. Both meet the electrical requirements defined by the varistor voltage and surge current ratings. Application-specific energy requirements should be evaluated based on circuit transient profiles.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ROV20-361K and V230LA40AP are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.40.4000.

Q: What is the difference in operating temperature ranges?

A: The ROV20-361K operates from -40°C to 125°C. The V230LA40AP operates from -55°C to 85°C. Application temperature requirements should be evaluated to confirm compatibility.
