V130LS20APX2855 Equivalent & Substitute Parts

Part Overview

The V130LS20APX2855 is a 205 V, 6.5 kA disc varistor manufactured by Littelfuse Inc. in the LS series. This transient voltage suppressor is designed for through-hole mounting applications requiring overvoltage protection in a 20mm disc package format. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging or series variants become necessary due to inventory constraints or supply chain requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the V130LS20APX2855 are qualified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Identical varistor voltage range (184.5 V – 225.5 V typical 205 V)
Identical surge current rating (6.5 kA)
Identical energy absorption (70 J)
Identical capacitance specification (1900 pF @ 1 MHz)
Identical operating temperature range (-55°C to 85°C)
Identical mounting type (Through Hole)
Identical package form factor (Disc 20mm)
Identical circuit count (1 Circuit)
Identical compliance certifications (ROHS3, REACH Unaffected)

Substitutes differ only in packaging format (Tape & Reel versus Cut Tape) and series designation (LS versus LT), which do not affect electrical performance or mechanical compatibility in the application.

Engineering Selection Recommendations

All three parts—V130LS20APX2855, V130LS20AP, and V130LT20AP—are active production components from Littelfuse Inc. with identical electrical specifications and ROHS3 compliance. Selection between these parts is determined by packaging requirements and inventory availability rather than electrical performance.

The V130LS20APX2855 is supplied in Tape & Reel format, suitable for automated assembly processes. The V130LS20AP and V130LT20AP are supplied in Cut Tape format, appropriate for manual or semi-automated handling. The series designation (LS versus LT) reflects internal Littelfuse product line organization and does not affect circuit performance or mechanical fit.

All parts maintain identical varistor voltage characteristics, surge current capacity, energy absorption, and thermal operating range. Direct substitution is electrically and mechanically valid across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can V130LS20AP be used as a direct replacement for V130LS20APX2855?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: V130LS20APX2855 is supplied in Tape & Reel, while V130LS20AP is supplied in Cut Tape. Electrical performance and circuit compatibility are unchanged.

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

A: The series designation reflects Littelfuse internal product categorization. Both LS and LT series parts in this comparison maintain identical electrical specifications, varistor voltage range, surge current rating, and package form factor. No functional difference exists for circuit application purposes.

Q: Are all three parts ROHS3 compliant?

A: Yes. V130LS20APX2855, V130LS20AP, and V130LT20AP are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape formats are supply and handling variations only. Electrical characteristics, varistor voltage, surge current capacity, and energy absorption remain identical across all packaging formats.

Q: Can these parts be used interchangeably in production assembly?

A: Electrical substitution is valid. Assembly process compatibility depends on equipment capability. Tape & Reel format (V130LS20APX2855) is optimized for automated pick-and-place systems. Cut Tape format (V130LS20AP, V130LT20AP) is suitable for manual or semi-automated assembly. Verify assembly equipment specifications before implementation.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -55°C to 85°C ambient temperature range. This specification is identical across V130LS20APX2855, V130LS20AP, and V130LT20AP.
