Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V470ZC05P is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (Min/Typ/Max): 423 V / 470 V / 517 V
• Surge current capacity: 400 A
• Maximum AC and DC voltage ratings: 300 V AC / 385 V DC
• Energy dissipation: 12 J
• Mounting configuration: Through Hole
• Package form factor: Disc 5mm
• Operating temperature range: -55°C ~ 85°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The V470ZA05P qualifies as a parametric equivalent because it maintains identical electrical specifications and mechanical form factor across all these parameters. The primary distinction is the series designation (ZA versus ZC), which reflects internal design variations within Littelfuse's varistor product line while preserving functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the V470ZC05P and V470ZA05P are active production parts from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: The V470ZA05P currently has higher inventory (19,765 units) compared to the V470ZC05P (719 units), making it suitable for high-volume procurement or long-term supply assurance.
• Compliance: Both parts meet ROHS3 and REACH requirements, ensuring regulatory compliance in regulated markets.
• Series continuity: If design documentation specifies the ZC series, the ZA series substitute maintains functional equivalence while potentially offering improved supply chain access.

No additional testing or qualification is required when substituting between these parts, as they are parametrically identical across all critical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can V470ZA05P be used as a direct replacement for V470ZC05P in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (470 V typical varistor voltage, 400 A surge current, 12 J energy rating) and mechanical form factors (through-hole, 5mm disc package). No circuit modifications are required.

Q: What is the difference between the ZC and ZA series designations?

A: The series designation reflects internal design variations within Littelfuse's varistor product line. Both series maintain identical performance characteristics for the 470 V, 400 A rating. The difference does not affect functional compatibility or electrical performance.

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

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). They are suitable for the same regulatory environments and applications.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection may be based on current availability, supplier preference, or inventory management strategy. Both parts are active in production with no planned obsolescence.

Q: Is the 5mm disc package compatible with existing PCB footprints designed for V470ZC05P?

A: Yes. Both parts use identical through-hole disc 5mm packaging, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes.
