Key Parameters

Substitute Part Grouping Explanation

Substitution of the V22ZT05P is determined by the following critical parameters:

• Varistor voltage rating (22V nominal)
• Surge current capacity (100A minimum)
• Maximum AC and DC voltage ratings (14V AC / 18V DC)
• Physical package form factor (Disc 5mm through-hole)
• Single circuit configuration
• RoHS3 compliance status

The B72205S0140K111 manufactured by EPCOS - TDK Electronics meets all these core electrical and mechanical requirements, establishing it as a direct equivalent for circuit applications requiring the V22ZT05P specification.

Parameter Comparison

Engineering Selection Recommendations

Both the V22ZT05P and B72205S0140K111 are active production components with identical electrical ratings and mechanical compatibility. Selection between these parts may be based on:

• Packaging format availability (V22ZT05P supplied in Tape & Reel; B72205S0140K111 supplied in Cut Tape)
• Inventory levels and lead time requirements
• Supply chain preferences for Littelfuse Inc. or EPCOS - TDK Electronics sourcing
• Operating temperature range requirements (V22ZT05P: -55°C to 85°C; B72205S0140K111: -40°C to 105°C)

Both components satisfy RoHS3 and REACH compliance requirements for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can B72205S0140K111 replace V22ZT05P in existing designs?

A: Yes. Both parts share identical varistor voltage ratings (22V nominal), surge current capacity (100A), maximum voltage ratings (14V AC / 18V DC), and disc 5mm through-hole package form factor. Direct substitution is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer identity, packaging format (Tape & Reel versus Cut Tape), energy rating (0.2J versus 0.4J), capacitance specifications, and operating temperature ranges. Electrical performance for transient voltage suppression is equivalent.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel or Cut Tape) affects supply chain logistics and component handling but does not alter electrical or mechanical performance in the circuit application.

Q: Are both parts compliant with regulatory requirements?

A: Yes. Both V22ZT05P and B72205S0140K111 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.40.4000.

Q: Which part should be selected for high-temperature applications?

A: The B72205S0140K111 supports an operating temperature range of -40°C to 105°C, extending to higher temperatures compared to the V22ZT05P range of -55°C to 85°C. Selection depends on specific application temperature requirements.
