Substitute Part Grouping Explanation

Substitution of the V8ZC05 is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

• Varistor voltage range: 6 V (minimum) to 11 V (maximum), with typical value of 8.5 V
• Surge current rating: 50 A minimum
• Maximum DC voltage rating: 5.5 V
• Maximum AC voltage rating: 4 V
• Energy dissipation: 0.1 J
• Mounting configuration: Through hole
• Package form factor: Disc 5mm
• Operating temperature range: -55°C to 85°C
• Single-circuit configuration

The V8ZC05P meets all specified parameters and represents a direct electrical and mechanical equivalent, with the distinction of active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The V8ZC05P is the direct substitute for the obsolete V8ZC05. Both components are manufactured by Littelfuse Inc. within the ZC series and maintain identical electrical specifications and mechanical form factors. The V8ZC05P carries active product status, ensuring continued availability and manufacturing support.

Both parts comply with ROHS3 requirements and carry 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 identical across both parts.

For new designs or component replacement in existing applications, the V8ZC05P is the appropriate selection due to its active status and equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the V8ZC05P directly replace the V8ZC05 in existing circuit designs?

A: Yes. The V8ZC05P is electrically and mechanically equivalent to the V8ZC05. All critical parameters—varistor voltage, surge current rating, voltage ratings, energy dissipation, and thermal operating range—are identical. The through-hole disc 5mm package form factor ensures mechanical compatibility.

Q: What is the primary difference between the V8ZC05 and V8ZC05P?

A: The V8ZC05 is classified as obsolete, while the V8ZC05P maintains active product status. The V8ZC05P is supplied in bulk packaging, whereas the V8ZC05 packaging specification was not provided. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications.

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

A: No. Both the V8ZC05 and V8ZC05P are ROHS3 compliant, carry identical ECCN and HTSUS classifications, and maintain MSL rating of 1 (Unlimited). Regulatory and environmental compliance is equivalent.

Q: What parameters determine substitution eligibility for this varistor?

A: Substitution is determined by matching varistor voltage range (6 V to 11 V typical 8.5 V), surge current rating (50 A), DC and AC voltage ratings (5.5 V and 4 V respectively), energy dissipation (0.1 J), mounting type (through hole), package form factor (disc 5mm), and operating temperature range (-55°C to 85°C).

Q: Is the V8ZC05P suitable for new production designs?

A: Yes. The V8ZC05P is an active product with full manufacturing support from Littelfuse Inc., making it the appropriate choice for new designs requiring 8.5 V, 50 A varistor protection in a through-hole disc 5mm package.
