V130LS2PX2855 Equivalent & Substitute Parts

Part Overview

The V130LS2PX2855 is a 205 V, 1.2 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts become necessary when tape & reel packaging is unavailable or when alternative series variants meet identical electrical specifications for your circuit protection requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the V130LS2PX2855 is determined by strict equivalence across all critical electrical and mechanical parameters. The allowed substitute parts maintain identical specifications for varistor voltage range (184.5 V minimum to 225.5 V maximum), surge current capacity (1.2 kA), energy rating (11 J), capacitance (180 pF @ 1 MHz), operating temperature range (-55°C to 85°C), and physical form factor (through-hole disc 7mm). The primary distinction among qualified substitutes is packaging format: the main part is supplied in tape & reel (TR) configuration, while substitute parts are available in cut tape (CT) packaging. Series designation (LS versus LT) represents internal Littelfuse manufacturing variants that do not affect electrical performance or circuit compatibility. All substitute parts maintain active product status, RoHS3 compliance, and REACH unaffected classification.

Engineering Selection Recommendations

All three parts—V130LS2PX2855, V130LS2P, and V130LT2P—are qualified for direct substitution based on identical electrical performance and mechanical compatibility. Selection between these parts should be driven by packaging requirements and inventory availability. The V130LS2PX2855 in tape & reel format is optimal for high-volume automated assembly processes. The V130LS2P and V130LT2P, both supplied in cut tape packaging, are suitable for lower-volume applications or manual assembly workflows. All parts maintain active product status with full RoHS3 compliance and REACH unaffected classification, ensuring regulatory compliance across all markets. No electrical performance degradation occurs when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can V130LS2P or V130LT2P be used as direct replacements for V130LS2PX2855?

A: Yes. All three parts are electrically and mechanically identical. The only difference is packaging format: V130LS2PX2855 is supplied in tape & reel, while V130LS2P and V130LT2P are supplied in cut tape. Circuit performance and component specifications remain unchanged.

Q: What is the difference between the LS and LT series designations?

A: Series designation (LS versus LT) represents internal Littelfuse manufacturing variants. Both series maintain identical electrical specifications, voltage ratings, surge current capacity, and operating temperature ranges. Series selection does not affect circuit compatibility or performance.

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

A: No. All three parts carry identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental certifications are equivalent across all variants.

Q: Which packaging format should I select for my application?

A: Tape & reel (TR) packaging is standard for high-volume automated pick-and-place assembly. Cut tape (CT) packaging is suitable for manual assembly, prototyping, or lower-volume production runs. Electrical performance is identical regardless of packaging selection.

Q: What inventory levels are available for each part?

A: V130LS2PX2855 (tape & reel) has 1,023 pieces in stock. V130LS2P (cut tape) has 10,287 pieces in stock. V130LT2P (cut tape) has 2,775 pieces in stock. Availability may vary; consult current inventory status for procurement planning.
