V300LC10P Equivalent & Substitute Parts

Part Overview

The V300LC10P is a 470 V, 2.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in disc form factor (10mm). This component is designed for transient overvoltage protection in electronic circuits and is currently in active production status. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or design flexibility across compatible series within the same manufacturer's product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V300LC10P is determined by strict equivalence across the following critical parameters:

• Maximum AC Volts: 300 V
• Maximum DC Volts: 405 V
• Varistor Voltage (Typical): 470 V
• Current - Surge: 2.5 kA
• Energy: 46 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Operating Temperature Range: -55°C to 85°C

The V300LA10P qualifies as a parametric equivalent because it maintains identical electrical ratings and mechanical specifications across all these parameters. Both parts belong to Littelfuse's varistor product line and share the same protective characteristics for transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V300LC10P and V300LA10P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts may be based on inventory availability or supply chain logistics, as both meet identical performance and regulatory requirements for transient voltage suppression applications in through-hole disc configurations.

Frequently Asked Questions (FAQ)

Q: Can V300LA10P be used as a direct replacement for V300LC10P?

A: Yes. The V300LA10P is a parametric equivalent with identical electrical ratings (470 V typical varistor voltage, 2.5 kA surge current, 46 J energy), mechanical specifications (10mm disc, through-hole mounting), and operating temperature range (-55°C to 85°C). Both parts are ROHS3 compliant and REACH unaffected.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: maximum AC/DC voltage ratings, varistor voltage range, surge current capacity, energy rating, number of circuits, mounting type, package form factor, and operating temperature range. All these parameters must match exactly between the main part and substitute.

Q: Are there any differences in packaging or handling between these parts?

A: Both parts share identical packaging specifications (Disc 10mm through-hole) and moisture sensitivity level (MSL 1 - Unlimited). No special handling differences apply between the two parts.

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

A: The LC and LA designations indicate different series within Littelfuse's varistor product line. However, for the V300 voltage class in 10mm disc form factor, both series maintain identical electrical and mechanical specifications, making them parametric equivalents.
