Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROV14H220L is based on the following critical electrical and mechanical parameters:

• Varistor voltage rating (22V nominal)
• Surge current capacity (2 kA)
• Maximum DC and AC voltage ratings (18V DC / 14V AC)
• Energy absorption capability (6.3 J)
• Single circuit configuration
• Through-hole mounting type
• Disc package form factor

The ERZ-V14D220 from Panasonic Electronic Components meets these core substitution criteria. Both parts share identical nominal varistor voltage, surge current rating, and energy specifications. Mechanical compatibility is maintained through through-hole mounting and disc packaging, though physical dimensions differ slightly (14mm vs 15.5mm).

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V14D220 is the designated manufacturer-recommended substitute for the ROV14H220L. Both components maintain identical electrical performance specifications for varistor voltage, surge current capacity, and energy absorption. Compliance certifications are equivalent, with both parts meeting ROHS3 requirements and carrying EAR99 ECCN classification.

The ERZ-V14D220 offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The Panasonic component is currently in stock with 952 units available.

Physical dimension differences (14mm vs 15.5mm disc diameter) require PCB layout verification to confirm mechanical fit within existing designs. The operating temperature range of the substitute extends to 85°C maximum, compared to 125°C for the original part; applications requiring operation above 85°C require thermal analysis.

Frequently Asked Questions (FAQ)

Q: Can the ERZ-V14D220 directly replace the ROV14H220L in existing designs?

A: Electrical substitution is valid based on matching varistor voltage, surge current, and energy ratings. Mechanical verification is required due to disc diameter difference (15.5mm vs 14mm). PCB layout and mounting clearance must be confirmed before implementation.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs active), operating temperature maximum (125°C vs 85°C), capacitance rating (11960 pF vs 20000 pF), and physical package size. Electrical performance for transient suppression is equivalent.

Q: Is the higher capacitance of the ERZ-V14D220 a concern?

A: Capacitance differences may affect high-frequency circuit behavior. Circuit-level analysis is necessary if the application involves frequencies where capacitive reactance is a design factor.

Q: Are both parts RoHS compliant?

A: Yes, both the ROV14H220L and ERZ-V14D220 meet ROHS3 compliance standards.

Q: What is the temperature operating range difference impact?

A: The ERZ-V14D220 maximum operating temperature is 85°C, while the original part operates to 125°C. Applications with ambient or component temperatures exceeding 85°C require thermal design review.
