V150LS10A Equivalent & Substitute Parts

Part Overview

The Littelfuse V150LS10A is a 240 V, 4.5 kA disc varistor designed for transient voltage suppression in through-hole applications. This part operates across a temperature range of -55°C to 85°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from the active product lines are available to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitute parts for the V150LS10A are qualified based on identical electrical and mechanical parameters. All substitute parts maintain the following critical specifications:

Varistor voltage range: 216 V – 264 V (typical 240 V)
Surge current capacity: 4.5 kA
Energy rating: 45 J
Package form factor: Disc 14mm through-hole
Operating temperature range: -55°C to 85°C
Capacitance: 800 pF @ 1 MHz
RoHS3 compliance and MSL 1 rating

Substitutes differ only in series designation (LS, LT, LU) and packaging format (Cut Tape or Tape & Reel). All listed substitutes are active products with current manufacturing status, ensuring long-term availability compared to the obsolete V150LS10A.

Engineering Selection Recommendations

All substitute parts listed are manufactured by Littelfuse Inc. and carry active product status, ensuring continued availability and manufacturing support. Each substitute maintains full electrical and mechanical equivalence to the V150LS10A across all critical parameters.

For new production designs, select from active series (LS, LT, or LU) based on packaging requirements. Cut Tape (CT) packaging suits manual assembly and small-volume applications, while Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly and high-volume production.

All substitutes are ROHS3 compliant with MSL 1 rating, meeting environmental and reliability standards equivalent to the original part. Series designation differences (LS, LT, LU) do not affect electrical performance or mechanical fit within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the V150LS10A?

A: Yes. All listed substitutes maintain identical electrical specifications (240 V typical varistor voltage, 4.5 kA surge current, 45 J energy) and mechanical form factor (Disc 14mm through-hole). The primary difference is product status (active vs. obsolete) and packaging format.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging is supplied as individual components on tape, suitable for manual assembly and low-volume applications. Tape & Reel (TR) packaging is continuous reel format optimized for automated assembly equipment. Both formats contain identical components; packaging choice depends on assembly process requirements.

Q: Why are there multiple part numbers with the same electrical specifications?

A: Part number variations reflect different manufacturing series (LS, LT, LU) and packaging configurations (CT or TR). The X-suffix designations (X1347, X2855) indicate specific reel configurations or manufacturing batches. All variants meet the same electrical and mechanical requirements.

Q: Is the V150LS10A still available for purchase?

A: The V150LS10A is classified as obsolete. However, 637 pieces remain in inventory. For new designs and ongoing production, active substitutes (V150LS10AP, V150LT10AP, V150LU10AP, and their packaging variants) are recommended to ensure long-term supply continuity.

Q: Do all substitutes carry the same compliance certifications?

A: Yes. All active substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original V150LS10A. All parts carry EAR99 ECCN and 8533.40.4000 HTSUS classification.
