V130LU2 Equivalent & Substitute Parts

Part Overview

The V130LU2 is a 205 V, 1.2 kA disc varistor manufactured by Littelfuse in the LU series. This transient voltage suppressor is designed for through-hole mounting applications requiring overvoltage protection. The V130LU2 is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. Active alternatives within the Littelfuse product line maintain identical electrical and mechanical specifications while offering current manufacturing status and improved availability.

Substitute Part Grouping Explanation

Substitution of the V130LU2 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Varistor voltage range: 184.5 V (Min) to 225.5 V (Max), with 205 V typical
Surge current capacity: 1.2 kA
Maximum AC and DC voltage ratings: 130 V AC / 175 V DC
Energy dissipation: 11 J
Single circuit configuration
Through-hole disc 7mm package
Operating temperature: -55°C to 85°C
RoHS3 compliance and MSL 1 rating

All substitute parts listed maintain these specifications. Differences exist only in series designation (LU, LT, LS) and packaging format (bulk, cut tape, or tape & reel). These variations do not affect electrical performance or mechanical compatibility.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Littelfuse and maintain active product status, ensuring continued availability and manufacturing support. Each substitute carries ROHS3 compliance and MSL 1 rating, meeting the same regulatory and environmental requirements as the original V130LU2.

Selection between substitutes should be based on packaging requirements and procurement volume:

For automated assembly with tape & reel feeding: V130LU2P, V130LU2PX2855, V130LT2PX2855, or V130LS2PX2855
For manual assembly or lower volumes: V130LT2P or V130LS2P (cut tape)
For highest current inventory availability: V130LS2P (10,287 units in stock)

All substitutes are electrically and mechanically interchangeable with the obsolete V130LU2 within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for V130LU2?

A: Yes. All listed substitutes maintain identical electrical specifications (205 V typical varistor voltage, 1.2 kA surge current, 11 J energy) and mechanical form factor (disc 7mm through-hole). The only differences are series designation and packaging format, which do not affect circuit performance or physical fit.

Q: What is the difference between the various series (LU, LT, LS)?

A: Series designation reflects internal manufacturing variations within Littelfuse's product line. All three series (LU, LT, LS) are electrically equivalent for this voltage and current rating, with identical performance parameters.

Q: Does packaging format affect electrical performance?

A: No. Bulk, cut tape, and tape & reel packaging formats are logistics variations only. The varistor component itself is identical across all packaging options. Selection should be based on assembly process requirements and procurement volume.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification and MSL 1 rating, matching the environmental and regulatory status of the original V130LU2.

Q: Which substitute has the best availability?

A: V130LS2P offers the highest inventory level at 10,287 units in stock, followed by V130LT2P at 2,775 units. Both are active products with cut tape packaging.
