Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ROV07-361K is determined by the following critical parameters:

• Varistor voltage rating (Min/Typ/Max): 324V / 360V / 396V
• Maximum AC and DC voltage ratings: 230V AC / 300V DC
• Mounting configuration: Through hole
• Number of circuits: Single circuit
• RoHS compliance status: ROHS3 Compliant

The ERZ-V07D361 qualifies as a substitute based on matching varistor voltage specifications, voltage ratings, circuit count, mounting type, and compliance certifications. While the substitute exhibits higher surge current capacity (1.75kA vs 1.2kA) and greater energy handling (32J vs 26J), these represent enhanced performance characteristics within the same functional category. Package dimensions differ (8.5mm vs 7mm), which may require mechanical validation in space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V07D361 is suitable for applications requiring ROV07-361K replacement based on electrical parameter alignment and active product status. The substitute maintains identical varistor voltage ratings and voltage operating limits, ensuring functional equivalence in transient suppression circuits.

The substitute's enhanced surge current capacity (1.75kA) and energy rating (32J) provide margin above the original specification without introducing incompatibility. The operating temperature range of the substitute (-40°C to 85°C) is narrower than the original part (-40°C to 125°C); applications requiring operation above 85°C require alternative solutions.

Both components meet ROHS3 compliance and carry identical REACH and ECCN classifications. The package dimension increase from 7mm to 8.5mm requires mechanical clearance validation in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can ERZ-V07D361 directly replace ROV07-361K in all applications?

A: Electrical substitution is valid based on matching varistor voltage ratings and voltage limits. Mechanical validation is required due to package size increase from 7mm to 8.5mm disc diameter. Temperature range compatibility must be confirmed for applications operating above 85°C.

Q: What are the key differences between these parts?

A: The substitute offers higher surge current handling (1.75kA vs 1.2kA) and greater energy absorption (32J vs 26J). Operating temperature maximum is reduced from 125°C to 85°C. Package diameter increases from 7mm to 8.5mm.

Q: Are both parts RoHS compliant?

A: Yes, both ROV07-361K and ERZ-V07D361 are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the product status difference?

A: ROV07-361K is obsolete, indicating discontinued manufacturing. ERZ-V07D361 is active, ensuring ongoing availability and supply chain continuity.

Q: Does the higher capacitance of the substitute affect circuit performance?

A: The capacitance difference (130pF vs 117pF at 1kHz) is within typical varistor manufacturing tolerance ranges and does not constitute a functional incompatibility for standard transient suppression applications.
