V130LT2 Equivalent & Substitute Parts

Part Overview

The V130LT2 is a 205 V, 1.2 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant with MSL 1 rating. The V130LT2 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Littelfuse offers multiple active alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the V130LT2 is determined by electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters: varistor voltage range (184.5 V minimum to 225.5 V maximum, 205 V typical), surge current rating (1.2 kA), maximum AC and DC voltage ratings (130 V AC, 175 V DC), energy dissipation (11 J), capacitance (180 pF @ 1 MHz), operating temperature range (-55°C to 85°C), and physical form factor (disc 7mm through-hole package).

Substitute parts differ only in series designation (LT, LS, LU) and packaging format (Cut Tape or Tape & Reel). These variations do not affect electrical performance or mechanical compatibility. All substitute parts are manufactured by Littelfuse Inc. and maintain ROHS3 compliance and MSL 1 rating.

Engineering Selection Recommendations

For new designs and production applications, select from the active substitute parts listed above. The V130LT2 is obsolete and should not be specified for new projects.

V130LT2P and V130LT2PX2855 maintain the LT series designation and are direct functional replacements. V130LT2P is available in Cut Tape packaging with 2775 units in stock, while V130LT2PX2855 is supplied in Tape & Reel format with 913 units available.

V130LS2P and V130LS2PX2855 represent the LS series alternative with equivalent electrical performance. V130LS2P in Cut Tape format offers the highest inventory availability at 10287 units. V130LS2PX2855 in Tape & Reel format provides 1023 units.

V130LU2P and V130LU2PX2855 are LU series variants supplied exclusively in Tape & Reel packaging, with 937 and 832 units respectively.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. Selection should be based on packaging requirements (Cut Tape versus Tape & Reel) and inventory availability for your production volume.

Frequently Asked Questions (FAQ)

Q: Can V130LT2 be replaced with V130LS2P or V130LU2P?

A: Yes. All substitute parts maintain identical electrical parameters: 205 V typical varistor voltage, 1.2 kA surge current, 130 V maximum AC, 175 V maximum DC, 11 J energy rating, and -55°C to 85°C operating temperature. Series designation (LT, LS, LU) does not affect electrical performance or mechanical compatibility in through-hole disc 7mm applications.

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 lower-volume applications and manual assembly. Tape & Reel (TR) packaging provides components on continuous reel format, optimized for automated pick-and-place assembly equipment. Electrical and mechanical specifications are identical between packaging formats.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity level rating, matching the compliance profile of the original V130LT2.

Q: Which substitute part has the best inventory availability?

A: V130LS2P in Cut Tape format offers the highest stock level at 10287 units. For Tape & Reel applications, V130LT2PX2855 provides 913 units and V130LU2P provides 937 units.

Q: Can I use V130LT2P as a direct replacement for V130LT2?

A: Yes. V130LT2P is an active LT series variant with identical electrical specifications and through-hole disc 7mm form factor. The primary difference is packaging format (Cut Tape versus bulk disc).
