Key Parameters

Substitute Part Grouping Explanation

Substitution of the V680LC80AP is determined by strict equivalence across the following critical parameters:

• Maximum AC Volts: 680 V
• Maximum DC Volts: 875 V
• Varistor Voltage (Typ): 1.1 kV
• Current - Surge: 4.5 kA
• Energy: 145 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• Operating Temperature Range: -55°C to 85°C
• Capacitance @ Frequency: 190 pF @ 1 MHz

The V680LA80AP qualifies as a parametric equivalent because it maintains identical electrical performance specifications and mechanical form factor. The primary difference is the series designation (LA versus LC), which reflects internal design variations within Littelfuse's product line while preserving all functional parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the V680LC80AP and V680LA80AP are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supply chain logistics and preferred distributor stock
• Design documentation and historical component usage
• Compliance requirements: both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99

No additional testing or validation is required when substituting between these parts, as they are parametrically equivalent across all specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can V680LA80AP be used as a direct replacement for V680LC80AP?

A: Yes. Both parts are parametrically equivalent across all critical electrical specifications (voltage ratings, surge current, energy dissipation) and mechanical form factor (14mm disc, through-hole mounting). No circuit redesign is required.

Q: What is the difference between the LC and LA series designations?

A: The series designation reflects internal design variations within Littelfuse's varistor product line. Both series maintain identical performance parameters for this voltage and current rating.

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

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification.

Q: What is the operating temperature range for both parts?

A: Both the V680LC80AP and V680LA80AP operate across -55°C to 85°C ambient temperature range.

Q: Are these parts suitable for PCB mounting or only through-hole breadboard applications?

A: These are through-hole components designed for insertion into PCB holes and secured by solder. They are not surface-mount devices.

Q: What is the moisture sensitivity level for these varistors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
