Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROV20-102K is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (1 kV nominal, 900 V minimum to 1.1 kV maximum)
• Surge current capacity (6.5 kA)
• Maximum DC voltage (825 V) and maximum AC voltage (625 V)
• Mounting type (through hole)
• Package form factor (disc 20mm)
• Number of circuits (1)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The V625LA80BP meets all these core electrical and mechanical requirements and is identified as the manufacturer-recommended substitute. Both components share identical voltage ratings, surge current capacity, and physical packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

The V625LA80BP is the appropriate substitute for the ROV20-102K based on the following factors:

Electrical Equivalence: Both components maintain identical varistor voltage ratings (1 kV nominal), surge current capacity (6.5 kA), and voltage operating limits (825 V DC, 625 V AC). These parameters ensure functional compatibility in transient voltage suppression circuits.

Physical Compatibility: Both components utilize identical through-hole mounting and disc 20mm package specifications, enabling direct mechanical replacement without PCB redesign.

Regulatory Compliance: Both components are ROHS3 compliant, REACH unaffected, and classified under EAR99, satisfying regulatory requirements for equivalent component selection.

Product Status: The V625LA80BP is classified as active, providing assured long-term availability and supply chain continuity compared to the obsolete ROV20-102K.

Frequently Asked Questions (FAQ)

Q: Can the V625LA80BP be used as a direct replacement for the ROV20-102K?

A: Yes. Both components share identical electrical ratings (1 kV varistor voltage, 6.5 kA surge current, 825 V DC maximum) and physical specifications (through-hole, disc 20mm package). Direct substitution is supported without circuit modification.

Q: What are the key differences between these components?

A: The primary differences are product status (ROV20-102K is obsolete; V625LA80BP is active) and energy absorption capacity (ROV20-102K: 448J; V625LA80BP: 230J). The V625LA80BP also specifies a narrower operating temperature range (-55°C to 85°C versus -40°C to 125°C) and different capacitance specifications. These differences do not affect substitution validity for standard transient voltage suppression applications.

Q: Are there any packaging differences?

A: Both components are supplied in through-hole disc 20mm packages. The ROV20-102K was supplied with unspecified packaging, while the V625LA80BP is supplied in bulk packaging. This does not affect electrical or mechanical compatibility.

Q: Do both components meet the same regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.40.4000).

Q: Which component should be selected for new designs?

A: The V625LA80BP should be selected for new designs due to its active product status, ensuring long-term availability and supply chain support.
