V385LC7P Equivalent & Substitute Parts

Part Overview

The V385LC7P is a 620V 1.2kA disc varistor manufactured by Littelfuse, designed for transient voltage suppression applications. This through-hole component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant. The part is currently active in production with 1172 units in stock. Equivalent substitute parts may be required due to inventory constraints, supply chain considerations, or design flexibility needs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The V385LA7P qualifies as a parametric equivalent to the V385LC7P based on strict alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical maximum AC voltage rating: 385 V
• Identical maximum DC voltage rating: 505 V
• Identical varistor voltage range: 558 V (Min) to 682 V (Max), with 620 V typical
• Identical surge current capacity: 1.2 kA
• Identical energy dissipation: 27 J
• Identical circuit count: 1
• Identical capacitance specification: 60 pF @ 1 MHz
• Identical operating temperature range: -55°C to 85°C
• Identical mounting type and package: Through Hole Disc 7mm
• Identical compliance certifications: ROHS3, REACH Unaffected

The only distinction between these parts is the internal series designation (LC versus LA), which does not affect functional performance or compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V385LC7P and V385LA7P are active production components from Littelfuse with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and supply chain requirements, as they are electrically and mechanically identical. The V385LA7P currently maintains higher inventory levels (3158 units) compared to the V385LC7P (1172 units), making it a viable alternative for procurement planning. Both parts meet identical compliance and certification requirements, ensuring no regulatory or environmental restrictions apply to either option.

Frequently Asked Questions (FAQ)

Q: Can the V385LA7P be used as a direct replacement for the V385LC7P?

A: Yes. The V385LA7P is a parametric equivalent with identical electrical ratings, surge current capacity, energy dissipation, operating temperature range, and physical package specifications. Direct substitution is supported without circuit modification.

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

A: The series designation (LC versus LA) represents an internal Littelfuse product line classification and does not affect electrical performance, mechanical compatibility, or functional characteristics in circuit applications.

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

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). No compliance restrictions apply to either component.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts feature identical through-hole mounting specifications and disc 7mm package dimensions, allowing direct PCB footprint compatibility without design revision.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supplier lead times. Both parts are active production components with identical specifications and certifications, making either suitable for new design implementations.
