V22ZA2 Equivalent & Substitute Parts

Part Overview

The V22ZA2 is a 22 V, 500 A Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse in a through-hole disc package (10mm). This component is designed for transient voltage protection in electronic circuits with a single circuit configuration.

The V22ZA2 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this protection specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V22ZA2 is determined by strict equivalence across the following critical parameters:

• Varistor voltage specification: 22 V nominal (19.8 V – 24.2 V range)
• Surge current rating: 500 A minimum
• Energy absorption capacity: 2 J
• Single circuit configuration
• Through-hole mounting in disc 10mm package
• Operating temperature range: -55°C to 85°C
• Capacitance at 1 MHz: 4500 pF
• RoHS3 compliance and MSL Level 1 rating

Only parts meeting all these electrical and mechanical specifications are considered direct substitutes. Packaging format (bulk vs. tape/reel) does not affect electrical equivalence but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The V22ZA2P is a direct electrical and mechanical equivalent to the V22ZA2. Both parts share identical electrical specifications across all critical parameters: varistor voltage, surge current rating, energy absorption, capacitance, and operating temperature range.

The primary distinction is product status: the V22ZA2 is obsolete, while the V22ZA2P is active and currently in production. This status difference ensures long-term component availability and supply chain continuity.

Both parts meet ROHS3 compliance and carry MSL Level 1 rating, confirming equivalent environmental and regulatory standing. The V22ZA2P is available in bulk packaging, which is standard for active production components.

For new designs, repairs, and production continuity where the V22ZA2 specification is required, the V22ZA2P is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the V22ZA2P be used as a direct replacement for the V22ZA2?

A: Yes. The V22ZA2P meets all electrical and mechanical specifications of the V22ZA2, including varistor voltage (22 V), surge current (500 A), energy absorption (2 J), package type (disc 10mm through-hole), and operating temperature range (-55°C to 85°C). Both parts are ROHS3 compliant with MSL Level 1 rating.

Q: What is the difference between the V22ZA2 and V22ZA2P?

A: The V22ZA2 is obsolete; the V22ZA2P is active production. Electrical specifications are identical. The V22ZA2P is supplied in bulk packaging format.

Q: Are there any compatibility concerns when substituting the V22ZA2 with the V22ZA2P?

A: No compatibility concerns exist. Both parts are through-hole mounted in identical disc 10mm packages and share the same electrical characteristics. PCB layout and circuit design require no modification.

Q: What packaging formats are available for the V22ZA2P?

A: The V22ZA2P is available in bulk packaging. Confirm packaging requirements with your supplier for specific procurement needs.

Q: Are both parts RoHS compliant?

A: Yes. Both the V22ZA2 and V22ZA2P are ROHS3 compliant and carry MSL Level 1 (unlimited moisture sensitivity level).
