V140LT2P Equivalent & Substitute Parts

Part Overview

The V140LT2P is a 220 V, 1.2 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the LT series. This through-hole disc component (7mm) is designed for transient voltage protection applications requiring surge current handling and energy dissipation capabilities. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to packaging availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The V140LS2P qualifies as a parametric equivalent to the V140LT2P based on strict electrical and mechanical compatibility. Both parts share identical specifications across all critical substitution parameters: maximum AC/DC voltage ratings, varistor voltage range (198–242 V typical 220 V), surge current capacity (1.2 kA), energy dissipation (12 J), circuit count (1), capacitance (160 pF @ 1 MHz), operating temperature range (−55 to +85°C), mounting type (through hole), and package form factor (disc 7mm). Both components are manufactured by Littelfuse Inc., maintain active product status, and comply with ROHS3 and REACH requirements. The primary distinction is packaging format: V140LT2P is supplied in Tape & Reel (TR) configuration, while V140LS2P is supplied in Cut Tape (CT) configuration. This packaging difference does not affect electrical performance or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both V140LT2P and V140LS2P are active Littelfuse products with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements rather than electrical performance, as all functional parameters are identical. The V140LT2P in Tape & Reel packaging is suitable for high-volume automated assembly operations. The V140LS2P in Cut Tape packaging accommodates lower-volume applications or manual assembly workflows. Both parts operate across the full −55 to +85°C temperature range and maintain consistent electrical characteristics throughout this range. Component selection should confirm that the chosen packaging format aligns with the assembly process and supply chain logistics of the application.

Frequently Asked Questions (FAQ)

Q: Can V140LS2P be used as a direct replacement for V140LT2P in circuit design?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance or component functionality.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Cut Tape packaging supplies the same components on tape segments, suitable for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Are there any thermal or environmental performance differences between these parts?

A: No. Both V140LT2P and V140LS2P operate across the identical temperature range (−55 to +85°C) and maintain the same electrical specifications under all operating conditions. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both V140LT2P and V140LS2P are ROHS3 compliant and REACH unaffected. They carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000).

Q: Which part should be selected for high-volume production?

A: V140LT2P (Tape & Reel) is the standard choice for high-volume automated assembly due to reel compatibility with standard pick-and-place equipment. V140LS2P (Cut Tape) is suitable for lower-volume or manual assembly scenarios.

Q: Are the varistor voltage characteristics identical between these parts?

A: Yes. Both parts have identical varistor voltage specifications: minimum 198 V, typical 220 V, maximum 242 V. Surge current capacity (1.2 kA) and energy dissipation (12 J) are also identical.
