V385LA20AP Equivalent & Substitute Parts

Part Overview

The V385LA20AP is a 620 V, 4.5 kA transient voltage suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 14mm package. This component is designed for transient overvoltage protection in electronic circuits and is currently in active production status. Substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements while maintaining equivalent electrical and mechanical performance.

• Maximum DC Volts: 505 V
• Varistor Voltage (Typical): 620 V
• Current - Surge: 4.5 kA
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Both substitute parts listed below meet all these core electrical and mechanical requirements and are approved manufacturer alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V385LA20AP, B72214S0381K101, and MOV14V385Y—are active production components from established manufacturers and meet ROHS3 compliance and REACH unaffected status. Selection among these equivalents should be based on:

• Availability and lead time from your supply chain
• Packaging preference (Bulk for V385LA20AP and B72214S0381K101; Bag for MOV14V385Y)
• Operating temperature requirements for your specific application environment
• Manufacturer preference or qualification requirements within your organization

All three parts are electrically and mechanically interchangeable for applications requiring 385 V AC / 505 V DC transient voltage suppression with 4.5 kA surge current capacity in a through-hole disc 14mm configuration.

Frequently Asked Questions (FAQ)

Q: Can B72214S0381K101 be used as a direct replacement for V385LA20AP?

A: Yes. Both parts share identical electrical specifications (385 V AC, 505 V DC, 620 V typical varistor voltage, 4.5 kA surge current) and the same through-hole disc 14mm package. The primary differences are manufacturer (EPCOS - TDK vs. Littelfuse), operating temperature range (-40°C ~ 105°C vs. -55°C ~ 85°C), and energy rating (80J vs. 85J).

Q: Can MOV14V385Y be used as a direct replacement for V385LA20AP?

A: Yes. MOV14V385Y meets all core electrical and mechanical requirements. It is supplied in Bag packaging rather than Bulk, has an extended operating temperature range (-40°C ~ 125°C), and a higher energy rating (128J).

Q: What are the key differences between the three parts?

A: All three parts are electrically equivalent. Differences include manufacturer, operating temperature range, energy dissipation rating, capacitance values, and packaging format. The varistor voltage, surge current, and package type are identical across all three.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with the same HTSUS code (8533.40.4000).

Q: Which part should I select if my application operates at extreme temperatures?

A: MOV14V385Y offers the widest operating temperature range (-40°C ~ 125°C), followed by B72214S0381K101 (-40°C ~ 105°C). V385LA20AP is rated -55°C ~ 85°C. Select based on your specific application temperature requirements.
