Key Parameters

Substitute Part Grouping Explanation

Substitution of the V480LC7P is determined by equivalence across the following critical parameters:

• Maximum AC and DC voltage ratings (480 V AC / 640 V DC)
• Varistor voltage specification (750 V typical, 675 V – 825 V range)
• Surge current capacity (1.2 kA)
• Energy dissipation capability (35 J)
• Physical form factor (Disc 7mm through-hole)
• Electrical characteristics (50 pF capacitance @ 1 MHz, single circuit)
• Environmental compliance (ROHS3, MSL 1, REACH Unaffected)
• Operating temperature range (-55°C to 85°C)

The V480LA7P meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance specifications and mechanical compatibility, differing only in manufacturer series designation (LC versus LA).

Parameter Comparison

Engineering Selection Recommendations

Both the V480LC7P and V480LA7P are active production components manufactured by Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences. The V480LA7P currently maintains higher inventory levels (4700 units) compared to the V480LC7P (884 units). Both parts carry ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The through-hole disc 7mm form factor ensures direct mechanical and electrical compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can V480LA7P be used as a direct replacement for V480LC7P?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical parameters, including 750 V typical varistor voltage, 1.2 kA surge current, 35 J energy dissipation, and 50 pF capacitance at 1 MHz. The physical form factor (Disc 7mm through-hole) and operating temperature range (-55°C to 85°C) are identical. The series designation difference (LA versus LC) does not affect functional performance.

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

A: No. Both V480LC7P and V480LA7P carry identical compliance certifications: ROHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status. Both are classified under ECCN EAR99 and HTSUS 8533.40.4000.

Q: What are the critical parameters for substitution eligibility?

A: Substitution eligibility is determined by matching maximum AC/DC voltage ratings (480 V AC / 640 V DC), varistor voltage specification (750 V ±75 V), surge current capacity (1.2 kA), energy dissipation (35 J), package form factor (Disc 7mm), and operating temperature range (-55°C to 85°C). All these parameters must remain constant across substitute parts.

Q: Can these parts be used in applications requiring different voltage ratings?

A: No. The V480LC7P and V480LA7P are specifically rated for 480 V AC and 640 V DC maximum operation. Applications requiring different voltage specifications require alternative part numbers with corresponding voltage ratings.

Q: What is the significance of the series designation (LC versus LA)?

A: The series designation indicates internal manufacturing or design revision within the Littelfuse product line. From an engineering perspective, both LC and LA series parts meet identical electrical and mechanical specifications for this voltage and current rating, making them functionally interchangeable.
