V22ZC2 Equivalent & Substitute Parts

Part Overview

The V22ZC2 is a 22 V, 500 A Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (10mm). This component is designed for transient voltage protection in electronic circuits with a single circuit configuration.

The V22ZC2 is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The substitute part V22ZC2P maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the V22ZC2 is based on strict equivalence across all critical electrical and mechanical parameters. The allowed substitution criteria are:

• Varistor voltage specification: 22 V nominal (19.8 V – 24.2 V range)
• Surge current rating: 500 A
• Maximum AC/DC voltage ratings: 14 V AC / 18 V DC
• Energy dissipation: 2 J
• Capacitance: 4500 pF @ 1 MHz
• Operating temperature range: -55°C to 85°C
• Package configuration: Through-hole disc 10mm
• Number of circuits: 1
• Compliance standards: ROHS3 Compliant

The V22ZC2P is a direct functional equivalent manufactured by the same supplier (Littelfuse Inc.) with identical electrical performance and mechanical form factor. The primary distinction is product status: V22ZC2P is active, whereas V22ZC2 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The V22ZC2P is the direct replacement for the obsolete V22ZC2. Both components are manufactured by Littelfuse Inc. and share identical electrical specifications and mechanical packaging. The V22ZC2P maintains active product status, ensuring continued availability and manufacturing support.

Both parts comply with ROHS3 standards and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The ECCN classification (EAR99) and HTSUS code (8533.40.4000) are consistent across both parts.

For applications currently using the V22ZC2, direct substitution with V22ZC2P is appropriate without circuit redesign or performance re-evaluation, provided that the bulk packaging format of the V22ZC2P is compatible with procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can V22ZC2P be used as a direct replacement for V22ZC2?

A: Yes. The V22ZC2P is electrically and mechanically identical to the V22ZC2. All critical parameters—varistor voltage, surge current, energy dissipation, capacitance, and operating temperature range—are equivalent. The primary difference is product status: V22ZC2P is active, while V22ZC2 is obsolete.

Q: What is the difference between V22ZC2 and V22ZC2P?

A: The components are functionally identical. The "P" suffix in V22ZC2P indicates bulk packaging format. V22ZC2 is obsolete; V22ZC2P is active and currently manufactured.

Q: Are there any packaging considerations when switching from V22ZC2 to V22ZC2P?

A: Both parts use the same through-hole disc 10mm package configuration. The V22ZC2P is supplied in bulk packaging, which may differ from the original V22ZC2 packaging format. Verify that bulk packaging is compatible with your assembly and procurement processes.

Q: What compliance certifications apply to both parts?

A: Both V22ZC2 and V22ZC2P are ROHS3 compliant. The V22ZC2P carries additional REACH Unaffected status. Both parts have MSL rating 1 (Unlimited), indicating no moisture sensitivity requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. No circuit modifications are required. The electrical performance, thermal characteristics, and mechanical form factor are identical, enabling direct substitution in PCB layouts and circuit designs.
