Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROV10-751K is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (675V minimum to 825V maximum range)
• Maximum AC and DC voltage specifications (460V AC / 615V DC)
• Package form factor (Disc 10mm through-hole)
• Operating temperature range (-40°C to 85°C)
• Number of circuits (single circuit configuration)
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

The ERZ-V10D751 from Panasonic Electronic Components meets all these criteria. While this substitute exhibits a higher surge current rating (4.6kA versus 2.5kA) and increased energy capacity (100J versus 90J), these represent enhanced performance characteristics within the same electrical and mechanical envelope, making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V10D751 is the designated manufacturer-recommended substitute for the ROV10-751K. Both components maintain identical voltage specifications and thermal operating ranges, ensuring functional compatibility in existing circuit designs. The ERZ-V10D751 carries active product status, providing assured long-term availability and supply chain continuity compared to the obsolete ROV10-751K.

Both parts satisfy RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The identical package geometry (Disc 10mm through-hole) permits direct mechanical substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the ERZ-V10D751 be used as a direct replacement for the ROV10-751K?

A: Yes. Both components share identical varistor voltage ratings (750V typical), maximum AC/DC voltage specifications (460V AC / 615V DC), package form factor (Disc 10mm), and operating temperature range (-40°C to 85°C). The ERZ-V10D751 provides enhanced surge current handling (4.6kA versus 2.5kA) and energy capacity (100J versus 90J) within the same electrical and mechanical specifications.

Q: What is the primary reason for substitution?

A: The ROV10-751K is classified as obsolete. The ERZ-V10D751 is an active product from Panasonic, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: No. Both components are RoHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: Will the higher surge current rating of the ERZ-V10D751 affect circuit performance?

A: No. The higher surge current rating (4.6kA) represents enhanced performance capability. The component will operate within the same voltage and thermal parameters as the original part.

Q: Are the physical dimensions identical?

A: Yes. Both components use the Disc 10mm through-hole package, permitting direct mechanical substitution without PCB layout modifications.
