V480LS80B Equivalent & Substitute Parts

Part Overview

The V480LS80B is a 732.5 V, 6.5 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, which necessitates identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts are selected based on matching core parameters: varistor voltage rating, surge current capacity, energy dissipation, and physical form factor.

Substitute Part Grouping Explanation

Substitution of the V480LS80B is determined by strict equivalence across the following critical parameters:

Varistor voltage rating (675 V – 790 V range, 732.5 V typical)
Surge current capacity (6.5 kA)
Energy dissipation (180 J)
Physical form factor (Disc 20mm, through-hole mounting)
Electrical characteristics (550 pF capacitance @ 1 MHz, -55°C to 85°C operating range)
Compliance standards (ROHS3 Compliant, MSL 1)

All substitute parts listed maintain these parameters identically. Differences exist only in series designation (LS, LT, LU) and packaging configuration (bulk vs. tape & reel with quantity indicators). Series designation and packaging do not affect electrical performance or mechanical compatibility.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing environments. The V480LS80B, being obsolete, should be replaced with any active equivalent from the substitute list.

Selection among active alternatives is determined by:

Series preference: LS series maintains direct lineage to the original part number. LT and LU series are parametrically equivalent alternatives.
Packaging requirement: Bulk packaging is not available among active alternatives; tape & reel (TR) packaging is standard for all active substitutes.
Quantity indicator: BPX10 and BPX2855 designations indicate specific reel quantities; BP indicates standard reel configuration.
Inventory availability: All active alternatives maintain stock levels exceeding 600 units.

All substitute parts maintain identical electrical performance, thermal characteristics, and mechanical form factor. Direct pin-for-pin and footprint compatibility is assured.

Frequently Asked Questions (FAQ)

Q: Can V480LS80B be directly replaced with V480LS80BP? A: Yes. Both parts share identical electrical specifications (732.5 V varistor voltage, 6.5 kA surge current, 180 J energy) and physical form factor (Disc 20mm, through-hole). The difference is packaging: V480LS80B is bulk; V480LS80BP is tape & reel. Electrical performance and mechanical compatibility are identical.

Q: What is the difference between LS, LT, and LU series? A: Series designation indicates internal design variants within the Littelfuse varistor product line. All three series maintain identical electrical parameters for this voltage and current rating. Selection among series is based on availability and manufacturing preference; no electrical or mechanical differences affect circuit performance.

Q: Are BPX10 and BPX2855 designations interchangeable? A: Yes, from an electrical and mechanical standpoint. These designations indicate different reel quantities for tape & reel packaging. The varistor itself is identical. Selection depends on procurement quantity requirements and inventory management.

Q: Is the V480LS80B compatible with automated assembly equipment? A: The V480LS80B uses bulk packaging. For automated assembly, tape & reel packaged alternatives (V480LS80BP, V480LS80BPX10, V480LS80BPX2855) are recommended, as they are compatible with standard pick-and-place equipment.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All active substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original V480LS80B specifications.
