V575LA80C Equivalent & Substitute Parts

Part Overview

The V575LA80C is a 910 V, 10 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the C-III series. This through-hole disc component (20mm) is designed for single-circuit transient voltage suppression applications with a maximum AC voltage rating of 575 V and energy dissipation capacity of 460 J. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V575LA80C is determined by strict equivalence across the following critical parameters:

• Varistor Voltage (Typical): 910 V nominal rating
• Varistor Voltage Range: 819 V minimum to 1.001 kV maximum
• Current - Surge Rating: 10 kA
• Maximum AC Volts: 575 V
• Energy Dissipation: 460 J
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• Number of Circuits: 1
• Operating Temperature Range: -55°C to 85°C

The V575LA80CP is a direct substitute that maintains identical electrical specifications and mechanical form factor. The primary distinction is packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The V575LA80CP is the direct equivalent substitute for the obsolete V575LA80C. Both components are manufactured by Littelfuse Inc. within the C-III series and maintain identical electrical and mechanical specifications across all critical parameters including varistor voltage, surge current rating, energy dissipation, and thermal operating range.

The V575LA80CP carries Active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000), confirming full compatibility for applications requiring the original V575LA80C specifications.

The packaging difference (bulk for V575LA80CP versus unspecified for V575LA80C) does not affect electrical or mechanical performance and represents a standard variation in distribution format.

Frequently Asked Questions (FAQ)

Q: Can the V575LA80CP be used as a direct replacement for the V575LA80C?

A: Yes. The V575LA80CP is electrically and mechanically identical to the V575LA80C across all specified parameters. Both components feature 910 V typical varistor voltage, 10 kA surge current rating, 460 J energy dissipation, and identical through-hole disc 20mm packaging.

Q: What is the primary difference between these two part numbers?

A: The V575LA80C is obsolete, while the V575LA80CP maintains Active product status. The V575LA80CP is supplied in bulk packaging. All electrical specifications and mechanical form factors are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000) and moisture sensitivity levels (MSL 1 - Unlimited).

Q: What parameters must remain constant when selecting a substitute varistor?

A: The varistor voltage range (819 V – 1.001 kV), surge current rating (10 kA), maximum AC voltage (575 V), energy dissipation (460 J), operating temperature range (-55°C to 85°C), and physical package (through-hole disc 20mm) must all remain unchanged for functional equivalence.

Q: Is the bulk packaging of the V575LA80CP suitable for my application?

A: Bulk packaging affects distribution and handling only. It does not alter component performance, electrical characteristics, or mechanical compatibility. The component itself is identical to the original specification.
