Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROV05-680K is determined by the following critical parameters:

• Varistor voltage rating (68V nominal) must remain within the specified tolerance range
• Maximum DC and AC voltage ratings must meet or exceed the original specification
• Operating temperature range must support the application environment
• Through-hole mounting configuration and disc package form factor
• RoHS3 compliance and REACH unaffected status for regulatory alignment

The ERZ-V05D680 from Panasonic Electronic Components meets these substitution criteria while maintaining electrical and mechanical compatibility with the original ROV05-680K specification.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V05D680 is a direct substitute for the obsolete ROV05-680K based on the following factors:

• Both components maintain identical varistor voltage ratings at 68V nominal with compatible tolerance ranges
• Voltage and temperature specifications are equivalent across both parts
• Both components carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• The ERZ-V05D680 offers enhanced surge current capability (250A versus 100A), providing improved transient protection margin
• Active product status of the ERZ-V05D680 ensures long-term availability and supply chain continuity
• Through-hole mounting configuration and disc package form factor remain consistent

Frequently Asked Questions (FAQ)

Q: Can the ERZ-V05D680 be used as a direct replacement for the ROV05-680K?

A: Yes. Both components share identical varistor voltage ratings (68V nominal), maximum DC/AC voltage specifications (56V DC, 40V AC), and operating temperature ranges (-40°C to 85°C). The ERZ-V05D680 maintains through-hole mounting compatibility and equivalent electrical performance.

Q: What is the primary difference between these two varistors?

A: The ERZ-V05D680 provides higher surge current capability at 250A compared to the ROV05-680K at 100A. This represents an enhanced protection margin for transient suppression applications without compromising voltage regulation characteristics.

Q: Are there package or form factor differences?

A: The ROV05-680K uses a 5mm disc package, while the ERZ-V05D680 uses a 7mm disc package. Both maintain through-hole mounting configuration. Physical dimensions should be verified against PCB layout requirements prior to implementation.

Q: Do both components meet current regulatory requirements?

A: Yes. Both the ROV05-680K and ERZ-V05D680 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: Why is the ROV05-680K listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The ERZ-V05D680 from Panasonic provides equivalent electrical specifications with active product status, ensuring continued availability for system maintenance and new implementations.
