Key Parameters

Substitute Part Grouping Explanation

Substitution of the V680LA100C is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (1.06 kV nominal, within 990 V – 1.13 kV range)
• Surge current capacity (10 kA minimum)
• Energy absorption (520 J)
• Mounting configuration (through-hole disc, 20mm)
• Single-circuit topology
• Operating temperature range (-55°C to 85°C)
• RoHS3 compliance

The V680LA100CP meets all these criteria and is classified as a direct substitute. The primary distinction between the main part and substitute is product status (obsolete vs. active) and packaging configuration (tape/reel vs. bulk).

Parameter Comparison

Engineering Selection Recommendations

The V680LA100CP is the direct equivalent for the obsolete V680LA100C. Both components are manufactured by Littelfuse Inc. within the C-III series and share identical electrical and mechanical specifications. The V680LA100CP maintains active product status, ensuring continued availability and supply chain support.

Selection of the V680LA100CP is appropriate for applications requiring:

• 1.06 kV nominal varistor voltage protection
• 10 kA transient surge current handling
• 520 J energy dissipation capacity
• Through-hole mounting in disc configuration
• ROHS3 compliance and environmental standards

The packaging difference (bulk vs. tape/reel) does not affect electrical performance and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the V680LA100CP directly replace the V680LA100C in existing designs?

A: Yes. The V680LA100CP is electrically and mechanically identical to the V680LA100C. All electrical parameters, thermal characteristics, and physical dimensions match exactly. The only differences are product status (active vs. obsolete) and packaging format.

Q: What is the significance of the packaging difference between these parts?

A: The V680LA100C is supplied in tape/reel format, while the V680LA100CP is supplied in bulk packaging. This distinction affects procurement and automated assembly processes but does not impact component performance or electrical characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the V680LA100C and V680LA100CP are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the V680LA100C classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation decisions. The V680LA100CP, as the active equivalent, is the recommended source for new procurement and system support.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching varistor voltage (1.06 kV), surge current rating (10 kA), energy absorption (520 J), mounting type (through-hole), package form (disc 20mm), and operating temperature range (-55°C to 85°C).
