Key Parameters

Substitute Part Grouping Explanation

Substitution of the V275LA20C is determined by strict equivalence across the following critical parameters:

• Varistor Voltage (Typical): 430 V nominal rating
• Varistor Voltage Range: 387 V minimum to 473 V maximum tolerance band
• Current - Surge Rating: 6.5 kA capacity
• Energy Absorption: 145 J
• Maximum AC Volts: 275 V
• Capacitance: 5000 pF @ 1 MHz
• Operating Temperature Range: -55°C to 85°C
• Mounting Type: Through Hole configuration
• Package / Case: Disc 14mm form factor
• Number of Circuits: Single circuit (1)
• Compliance: ROHS3 Compliant, MSL 1

The V275LA20CP qualifies as a direct substitute based on identical electrical specifications, mechanical packaging, and environmental ratings. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The V275LA20CP is the direct equivalent substitute for the V275LA20C. Both components are manufactured by Littelfuse Inc. within the C-III series and maintain identical electrical, thermal, and mechanical specifications. The V275LA20CP is currently in active production status, whereas the V275LA20C is obsolete. Both components meet ROHS3 compliance requirements and carry MSL 1 rating.

Selection of the V275LA20CP is appropriate for applications requiring the electrical and thermal characteristics of the V275LA20C. The primary consideration is packaging format: the V275LA20CP is supplied in bulk packaging, whereas the V275LA20C was supplied in standard packaging. This distinction does not affect component performance or compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the V275LA20CP be used as a direct replacement for the V275LA20C?

A: Yes. The V275LA20CP is electrically and mechanically equivalent to the V275LA20C. All critical parameters—varistor voltage, surge current rating, energy absorption, operating temperature range, and package dimensions—are identical. The components are interchangeable in circuit design and PCB layout.

Q: What is the difference between the V275LA20C and V275LA20CP?

A: The V275LA20C is obsolete, while the V275LA20CP is in active production. The V275LA20CP is supplied in bulk packaging format. Electrical and mechanical specifications are identical.

Q: Are there compliance differences between these parts?

A: No. Both the V275LA20C and V275LA20CP are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent.

Q: Does the bulk packaging of the V275LA20CP affect component performance?

A: No. Packaging format does not affect electrical performance, thermal characteristics, or reliability. Bulk packaging is a supply format distinction only.

Q: What are the critical parameters for substitution in this varistor category?

A: Substitution is determined by matching varistor voltage (430 V typical), surge current rating (6.5 kA), energy absorption (145 J), operating temperature range (-55°C to 85°C), and package form factor (Disc 14mm through-hole). All parameters must align for functional equivalence.
