• Varistor Voltage Range: 387 V minimum to 473 V maximum
• Current - Surge Rating: 6.5 kA transient current capacity
• Energy Rating: 145 J energy absorption capability
• Maximum AC Volts: 275 V continuous AC voltage rating
• Number of Circuits: Single circuit configuration
• Mounting Type: Through hole connection method
• Package / Case: Disc 14mm physical form factor
• Operating Temperature Range: -55°C to +85°C

The V275LC20CP is a direct manufacturer equivalent from Littelfuse Inc., differing only in packaging specification (bulk vs. standard) and product status (active vs. obsolete). All electrical and mechanical parameters are identical, confirming full functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The V275LC20CP is the primary substitute for the obsolete V275LC20C. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications and mechanical form factors. The V275LC20CP maintains active product status, ensuring continued availability and supply chain reliability.

Both parts comply with ROHS3 standards and carry MSL Level 1 (unlimited moisture sensitivity), confirming equivalent environmental and regulatory compliance. The V275LC20CP is suitable for direct replacement in all applications where the V275LC20C was originally specified, with no circuit redesign or validation required.

Frequently Asked Questions (FAQ)

Q: Can the V275LC20CP be used as a direct replacement for the V275LC20C?

A: Yes. The V275LC20CP is electrically and mechanically identical to the V275LC20C. All critical parameters—varistor voltage (430 V typical), surge current (6.5 kA), energy rating (145 J), and physical form factor (14mm disc)—are equivalent. The only difference is packaging specification and product status.

Q: Why is the V275LC20C listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The V275LC20CP, an active equivalent from the same manufacturer, is available as a replacement.

Q: Are there any compatibility concerns when substituting the V275LC20CP for the V275LC20C?

A: No compatibility concerns exist. Both parts are through-hole mounted disc components with identical electrical ratings and operating temperature ranges (-55°C to +85°C). PCB footprints and circuit connections remain unchanged.

Q: What is the difference between the V275LC20C and V275LC20CP?

A: The parts differ only in packaging specification (standard vs. bulk) and product lifecycle status (obsolete vs. active). All functional and electrical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the V275LC20C and V275LC20CP are ROHS3 compliant and carry MSL Level 1 rating.
