Key Parameters

Substitute Part Grouping Explanation

The V1000LC80AP has one parametric equivalent substitute: V1000LA80AP. This substitution is valid based on the following matching criteria:

• Identical varistor voltage specifications (1.5 kV Min, 1.65 kV Typ, 1.8 kV Max)
• Identical surge current rating (4.5 kA)
• Identical maximum AC and DC voltage ratings (1 kV AC, 1.2 kV DC)
• Identical energy absorption capacity (220 J)
• Identical capacitance at 1 MHz (130 pF)
• Identical operating temperature range (-55°C to 85°C)
• Identical mounting type and package (Through Hole, Disc 14mm)
• Identical number of circuits (1)
• Identical regulatory compliance (ROHS3, REACH Unaffected)

Both parts belong to the Littelfuse V1000 base product family and differ only in internal series designation (LC vs. LA), which does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both V1000LC80AP and V1000LA80AP are Active products with full ROHS3 compliance and REACH Unaffected status, making them suitable for current design implementations and regulatory requirements. The V1000LA80AP offers higher inventory availability (3406 units vs. 850 units), which may provide supply chain advantages for high-volume production or extended lead-time mitigation. Selection between these parts should be based on procurement availability and supply chain requirements, as all electrical and mechanical specifications are identical. Both parts are suitable for direct substitution in applications requiring 1.65 kV transient voltage suppression with 4.5 kA surge current capacity in through-hole disc configurations.

Frequently Asked Questions (FAQ)

Q: Can V1000LA80AP be used as a direct replacement for V1000LC80AP?

A: Yes. Both parts have identical electrical specifications (1.65 kV varistor voltage, 4.5 kA surge current, 220 J energy absorption), identical mechanical packaging (through-hole disc 14mm), and identical regulatory compliance. No circuit redesign or board layout modification is required.

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

A: The series designation (LC vs. LA) indicates internal manufacturing variants within the Littelfuse V1000 product family. These variants do not affect electrical performance, mechanical compatibility, or regulatory compliance.

Q: Are there any temperature or environmental limitations that differ between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 85°C) and have identical moisture sensitivity levels (MSL 1 - Unlimited). Environmental performance is equivalent.

Q: Can these varistors be used in AC and DC applications?

A: Yes. Both parts are rated for maximum AC voltage of 1 kV and maximum DC voltage of 1.2 kV, making them suitable for both AC and DC transient suppression applications within these voltage limits.

Q: What is the capacitance specification used for?

A: The capacitance value (130 pF @ 1 MHz) characterizes the varistor's high-frequency behavior and is relevant for applications involving RF interference or high-frequency transient events. Both substitute parts have identical capacitance specifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both V1000LC80AP and V1000LA80AP are supplied in through-hole disc packages (14mm diameter) suitable for PCB mounting via standard through-hole assembly processes.
