V480LA7 Equivalent & Substitute Parts

Part Overview

The V480LA7 is a 750 V, 1.2 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 7mm package. This component is designed for transient voltage suppression applications requiring single-circuit protection with 35 J energy rating.

The V480LA7 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this varistor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V480LA7 is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (675 V – 825 V range, 750 V typical)
• Surge current capacity (1.2 kA)
• Energy dissipation (35 J)
• Package form factor (Disc 7mm through-hole)
• Number of circuits (1)
• Operating temperature range (-55°C to +85°C)
• Electrical compliance (ROHS3)

Only parts matching all these specifications across the allowed parameter ranges qualify as direct substitutes. Packaging format (bulk vs. tape/reel) does not affect electrical equivalence but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The V480LA7P is a direct electrical and mechanical equivalent to the V480LA7. Both parts are manufactured by Littelfuse Inc. within the LA series and share identical electrical specifications across all critical parameters: 750 V typical varistor voltage, 1.2 kA surge current, 35 J energy rating, and disc 7mm through-hole package.

The primary distinction is product status: the V480LA7 is obsolete, while the V480LA7P is active. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification (MSL 1).

For new designs and production applications, the V480LA7P is the appropriate selection due to its active status and assured long-term availability. For legacy system repairs or maintenance where original part specifications must be preserved, the V480LA7P provides full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can V480LA7P be used as a direct replacement for V480LA7 in existing designs?

A: Yes. The V480LA7P is electrically and mechanically identical to the V480LA7. All electrical parameters, package dimensions, and performance characteristics are equivalent. The only difference is product status (active vs. obsolete) and packaging format (bulk vs. standard).

Q: What determines whether a part qualifies as a substitute for the V480LA7?

A: Substitution requires exact equivalence across varistor voltage rating (675–825 V range), surge current (1.2 kA), energy dissipation (35 J), package form (disc 7mm through-hole), circuit count (1), operating temperature range (-55°C to +85°C), and compliance certifications (ROHS3).

Q: Does packaging format (bulk vs. standard) affect electrical performance?

A: No. Packaging format affects only procurement, storage, and assembly processes. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are there any compliance or certification differences between V480LA7 and V480LA7P?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). No compliance or certification differences exist between the two parts.

Q: Why is the V480LA7 listed as obsolete?

A: The V480LA7 has been discontinued by the manufacturer. The V480LA7P remains in active production and is the recommended source for new component procurement.
