Key Parameters

Substitute Part Grouping Explanation

Substitution of the 90065-013 is determined by the following critical electrical and mechanical parameters:

• Varistor Voltage Rating: Nominal voltage must remain at 240 V (acceptable range: 212–268 V minimum to maximum)
• Surge Current Capacity: Minimum 22.5 kA required for equivalent protection
• Mounting Configuration: Chassis mount with blade terminal interface
• Number of Circuits: Single-circuit configuration
• Maximum AC Voltage: 150 V maximum continuous AC rating
• Energy Absorption: Minimum 200 J capacity

The substitute part V151DB40 meets these criteria while offering enhanced surge current capacity (40 kA) and improved energy handling (300 J), maintaining full electrical and mechanical compatibility within the DB series platform.

Parameter Comparison

Engineering Selection Recommendations

The V151DB40 is the manufacturer-recommended substitute for the obsolete 90065-013. Both components maintain identical nominal varistor voltage (240 V) and maximum AC voltage rating (150 V), ensuring direct electrical compatibility in existing circuit designs.

The V151DB40 offers the following advantages:

• Active Product Status: Ensures long-term availability and supply chain continuity
• Enhanced Surge Capacity: 40 kA rating exceeds the original 22.5 kA specification, providing increased transient protection margin
• Increased Energy Rating: 300 J capacity provides superior energy absorption compared to the original 200 J
• RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the original part is RoHS non-compliant
• Specified Operating Temperature Range: -55°C to 85°C provides defined thermal performance parameters

Both parts utilize identical DB series blade terminal architecture and chassis mount configuration, confirming mechanical interchangeability. The substitute part is suitable for direct replacement in applications requiring 240 V transient voltage suppression with single-circuit protection.

Frequently Asked Questions (FAQ)

Q: Can the V151DB40 directly replace the 90065-013 in existing designs?

A: Yes. Both components share identical varistor voltage ratings (240 V nominal), maximum AC voltage (150 V), mounting type (chassis mount), and blade terminal interface. The V151DB40 is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the higher surge current rating (40 kA vs. 22.5 kA)?

A: The V151DB40 provides increased surge current capacity, meaning it can handle larger transient events without degradation. This represents an enhancement over the original specification and does not create compatibility issues in applications designed for the 22.5 kA part.

Q: Does the RoHS3 compliance of the V151DB40 affect compatibility?

A: No. RoHS3 compliance indicates the substitute part meets current environmental standards and contains no restricted substances. This is a regulatory advantage with no negative impact on electrical or mechanical performance.

Q: Are there any package differences between these parts?

A: The 90065-013 uses "Chassis Mount, Blade Terminals" packaging, while the V151DB40 uses "Blade Type, Encased" packaging. Both configurations maintain the same blade terminal interface and chassis mount mounting type, ensuring physical compatibility in standard applications.

Q: Why is the 90065-013 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The V151DB40 is the active replacement within the DB series, offering equivalent or superior performance characteristics while maintaining full compatibility with existing circuit designs.
