V22ZC3 Equivalent & Substitute Parts

Part Overview

The V22ZC3 is a 22 V, 1 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (14mm). This component is designed for transient voltage protection in electronic circuits with a nominal varistor voltage of 22 V and surge current rating of 1 kA.

The V22ZC3 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V22ZC3 is determined by the following critical electrical and mechanical parameters:

• Varistor Voltage (Typical): Must be 22 V to maintain circuit protection threshold
• Varistor Voltage Range: Must fall within 19.8 V – 24.2 V for functional equivalence
• Current - Surge Rating: Must be 1 kA to handle transient events
• Energy Absorption: Must be 4 J for equivalent energy dissipation capability
• Maximum AC/DC Volts: Must match 14 V AC and 18 V DC operating limits
• Mounting Type: Must be Through Hole to fit existing PCB designs
• Package / Case: Must be Disc 14mm for mechanical compatibility
• Operating Temperature Range: Must support -55°C to 85°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The V22ZC3P is a direct substitute that meets all these criteria while offering improved product status (Active vs. Obsolete) and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The V22ZC3P is the recommended substitute for the obsolete V22ZC3. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications and mechanical form factors. The V22ZC3P maintains full ROHS3 compliance and carries Active product status, ensuring long-term availability and supply chain reliability.

The transition from V22ZC3 to V22ZC3P requires no circuit redesign, PCB layout modification, or thermal management changes. The parts are pin-compatible and functionally equivalent across all specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can V22ZC3P be used as a direct replacement for V22ZC3 in existing designs?

A: Yes. The V22ZC3P is electrically and mechanically identical to the V22ZC3. All electrical parameters, including varistor voltage (22 V typical), surge current rating (1 kA), energy absorption (4 J), and operating temperature range (-55°C to 85°C) are identical. The through-hole disc 14mm package ensures PCB compatibility without layout changes.

Q: What is the primary difference between V22ZC3 and V22ZC3P?

A: The V22ZC3P has Active product status, while the V22ZC3 is Obsolete. The V22ZC3P is supplied in Bulk packaging. These differences do not affect electrical or mechanical performance.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What parameters must match for a varistor to be considered a substitute for the V22ZC3?

A: Critical parameters include varistor voltage (22 V typical, 19.8 V – 24.2 V range), surge current rating (1 kA), energy absorption (4 J), maximum AC/DC voltage ratings (14 V AC, 18 V DC), operating temperature range (-55°C to 85°C), mounting type (Through Hole), and package form factor (Disc 14mm).

Q: Is the V22ZC3P available in the same packaging as the V22ZC3?

A: The V22ZC3P is supplied in Bulk packaging. Both parts use the same Disc 14mm through-hole package form factor for PCB mounting.
