V130LS20B Equivalent & Substitute Parts

Part Overview

The V130LS20B is a 205 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, making equivalent substitute parts necessary for ongoing design support and procurement. The electrical and mechanical specifications of this varistor remain consistent across the substitute part family, enabling direct functional replacement based on packaging and series variations.

Substitute Part Grouping Explanation

Substitution of the V130LS20B is determined by electrical parameter equivalence and mechanical compatibility. All substitute parts maintain identical electrical specifications: 205 V typical varistor voltage, 6.5 kA surge current, 70 J energy rating, and -55°C to 85°C operating temperature range. The substitute parts differ only in series designation (LS, LT, LU) and packaging format (Tape & Reel or Cut Tape), which do not affect electrical performance in the application circuit.

The key parameters governing substitution are:

Varistor voltage range (190 V minimum to 220 V maximum)
Surge current rating (6.5 kA)
Energy dissipation (70 J)
Through-hole disc 20mm form factor
Operating temperature range

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory compliance advantages over the obsolete V130LS20B. Selection among substitute parts should be based on packaging requirements and procurement volume:

For manual assembly or low-volume applications, V130LT20BP (Cut Tape packaging) offers the highest inventory availability at 4720 pieces. For automated assembly processes requiring tape and reel format, V130LS20BP, V130LS20BPX10, V130LS20BPX2855, V130LU20BP, V130LU20BPX10, and V130LU20BPX2855 are suitable alternatives. The series designation (LS, LT, LU) does not affect electrical performance and represents internal manufacturing variations within the Littelfuse product line.

Frequently Asked Questions (FAQ)

Q: Can V130LS20B be directly replaced with any of the listed substitute parts? A: Yes. All substitute parts maintain identical electrical specifications (205 V varistor voltage, 6.5 kA surge current, 70 J energy) and the same through-hole disc 20mm form factor. Substitution is electrically and mechanically compatible.

Q: What is the difference between LS, LT, and LU series designations? A: Series designation represents internal manufacturing variations within Littelfuse's varistor product line. All three series maintain identical electrical and mechanical parameters for this voltage and current rating. Selection between series should be based on packaging availability and procurement preferences.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are logistics and assembly considerations only. Electrical performance remains identical across all packaging variants.

Q: Why is V130LS20B marked as obsolete? A: Product obsolescence is a manufacturer lifecycle decision. Active substitute parts with identical specifications are available from Littelfuse to support ongoing applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute part has the best inventory availability? A: V130LT20BP (Cut Tape packaging) has the highest inventory at 4720 pieces, followed by V130LT20BPX2855 at 1012 pieces.
