V140LC2 Equivalent & Substitute Parts

Part Overview

The V140LC2 is a 220 V, 1.2 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 7mm package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement.

The V140LC2 operates within a varistor voltage range of 198 V to 242 V (typical 220 V) and is rated for maximum AC voltage of 140 V and maximum DC voltage of 180 V. With a surge current capacity of 1.2 kA and energy rating of 12 J, this varistor is designed for transient voltage protection in industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V140LC2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Varistor voltage range (198–242 V typical 220 V)
• Maximum AC voltage rating (140 V)
• Maximum DC voltage rating (180 V)
• Surge current capacity (1.2 kA)
• Energy dissipation (12 J)
• Single-circuit configuration
• Through-hole mounting with disc 7mm package geometry
• Operating temperature range (−55°C to +85°C)
• RoHS3 compliance

The V140LC2P is a direct functional equivalent manufactured by Littelfuse Inc. in the same LC series. It maintains identical electrical specifications and mechanical form factor while offering active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The V140LC2P is the primary substitute for the obsolete V140LC2. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The V140LC2P maintains active product status, ensuring long-term availability and supply chain continuity.

Both parts comply with ROHS3 standards and carry MSL rating 1 (unlimited moisture sensitivity), indicating robust handling characteristics suitable for standard manufacturing environments. The V140LC2P is available in bulk packaging, which may provide cost advantages for production volumes compared to the original part's packaging configuration.

Direct pin-for-pin and functional replacement is supported without circuit modification or re-qualification when transitioning from V140LC2 to V140LC2P.

Frequently Asked Questions (FAQ)

Q: Can V140LC2P be used as a direct replacement for V140LC2?

A: Yes. The V140LC2P is electrically and mechanically identical to the V140LC2 across all specified parameters, including varistor voltage range, surge current rating, energy dissipation, and package geometry. No circuit modifications are required.

Q: Why is the V140LC2 listed as obsolete?

A: Obsolete status indicates that the V140LC2 is no longer in active production. The V140LC2P, which shares identical specifications, is the active equivalent and recommended for new designs and ongoing procurement.

Q: Are there differences in packaging between V140LC2 and V140LC2P?

A: The V140LC2P is supplied in bulk packaging, whereas the original V140LC2 packaging configuration is not specified in the provided data. Both parts use the same disc 7mm through-hole package form factor and are mechanically interchangeable.

Q: What compliance certifications apply to both parts?

A: Both V140LC2 and V140LC2P are ROHS3 compliant and carry MSL rating 1 (unlimited), indicating compliance with environmental and moisture sensitivity standards applicable to electronic components.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical electrical specifications: 220 V typical varistor voltage (198–242 V range), 140 V maximum AC rating, 180 V maximum DC rating, 1.2 kA surge current capacity, and 12 J energy rating.
