V14E320PL4B Equivalent & Substitute Parts

Part Overview

The V14E320PL4B is a 510 V, 6 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This through-hole disc component (14mm) is designed for transient voltage protection in electronic circuits. The part is currently Active in product status with 842 units in stock. Substitute parts are necessary when the primary part number becomes unavailable or when alternative series options with identical electrical and mechanical specifications are required for procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V14E320PL4B are qualified based on the following critical parameters that determine functional equivalence:

• Maximum AC Volts: 320 V
• Maximum DC Volts: 420 V
• Varistor Voltage (Typ): 510 V
• Current - Surge: 6 kA
• Energy: 136 J
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• Operating Temperature: -55°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant

All substitute parts listed below match these parameters exactly. Substitution is valid across different series designations (UltraMOV™ and TMOV®) when all electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V14E320PL4B, V14E320P, and TMOV14RP320E—are Active products manufactured by Littelfuse Inc. and meet identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: V14E320P has the highest stock level (38,289 units), followed by TMOV14RP320E (2,699 units), and V14E320PL4B (842 units).
• Series preference: Both UltraMOV™ (V14E320PL4B, V14E320P) and TMOV® (TMOV14RP320E) series are equivalent for this voltage and current rating.
• Compliance requirements: All parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can V14E320P be used as a direct replacement for V14E320PL4B?

A: Yes. Both parts are manufactured by Littelfuse Inc., belong to the UltraMOV™ series, and share identical electrical specifications (510 V typical varistor voltage, 6 kA surge current, 136 J energy) and mechanical specifications (14mm disc, through-hole mounting, -55°C to 85°C operating range).

Q: What is the difference between the UltraMOV™ and TMOV® series?

A: For the 510 V, 6 kA rating in 14mm disc package, both series provide identical electrical and mechanical performance. TMOV14RP320E includes thermal protection as an additional feature. Series selection does not affect functional equivalence when all specified parameters match.

Q: Are all three parts suitable for the same circuit application?

A: Yes. All three parts meet the same electrical requirements (320 V AC maximum, 420 V DC maximum, 510 V typical varistor voltage) and mechanical requirements (through-hole disc 14mm, -55°C to 85°C operating temperature). They are functionally interchangeable in circuit design.

Q: Do these parts have different compliance certifications?

A: No. All three parts carry identical compliance status: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and EAR99 export classification.

Q: Which part should be selected for new designs?

A: Selection should prioritize availability and supply chain stability. V14E320P offers the highest inventory level. All three parts are Active products with no planned obsolescence indicated.
