Key Parameters

Substitute Part Grouping Explanation

Substitution of the V320LS20C is determined by strict equivalence across the following electrical and mechanical parameters:

• Varistor voltage specification (462 V – 558 V range)
• Surge current rating (6.5 kA)
• Energy absorption capacity (165 J)
• Maximum AC voltage rating (320 V)
• Single-circuit configuration
• Through-hole mounting with 14mm disc package
• Operating temperature range (-55°C to 85°C)
• Capacitance value (5000 pF @ 1 MHz)
• RoHS3 compliance and MSL rating

The V320LS20CP meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is packaging format: the V320LS20C is supplied in bulk form, while the V320LS20CP is supplied in Tape & Reel (TR) format. Both components are manufactured by Littelfuse Inc. within the C-III series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The V320LS20CP is a direct electrical and mechanical equivalent to the V320LS20C. Selection between these parts should be based on the following factors:

Product Status: The V320LS20CP is classified as Active, whereas the V320LS20C is Obsolete. For new designs or ongoing production, the V320LS20CP is the appropriate selection to ensure long-term supply chain availability and manufacturer support.

Packaging Considerations: The V320LS20C is supplied in bulk packaging, while the V320LS20CP is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments. Bulk packaging may be suitable for manual assembly or low-volume applications.

Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility across applications.

Inventory Status: The V320LS20CP currently has 872 pieces in stock, providing immediate availability for procurement.

Frequently Asked Questions (FAQ)

Q: Can the V320LS20CP be used as a direct replacement for the V320LS20C in existing designs?

A: Yes. The V320LS20CP is electrically and mechanically identical to the V320LS20C. All electrical parameters, including varistor voltage (510 V typical), surge current rating (6.5 kA), energy absorption (165 J), and operating temperature range (-55°C to 85°C) are identical. The components are interchangeable from a functional standpoint.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging supplies components loose or in standard containers, suitable for manual assembly or small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, designed for automated pick-and-place assembly equipment. Both formats contain the same component; the difference is in handling and assembly methodology.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the V320LS20C and V320LS20CP are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited). They share the same ECCN (EAR99) and HTSUS classification (8533.40.4000).

Q: Why is the V320LS20C listed as obsolete?

A: The V320LS20C has been discontinued by the manufacturer. The V320LS20CP remains in active production and is the current equivalent offering. For new procurement or design updates, the V320LS20CP should be specified.

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

A: Yes, provided the PCB design accommodates the through-hole mounting configuration and 14mm disc package footprint. Both parts use identical mounting specifications and can be installed in the same PCB holes without modification.
