V14E150 Equivalent & Substitute Parts

Part Overview

The V14E150 is a 240 V, 6 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This component is designed for single-circuit transient voltage suppression applications with a through-hole disc mounting configuration of 14mm. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V14E150 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Maximum AC Volts: 150 V
• Maximum DC Volts: 200 V
• Varistor Voltage (Typical): 240 V
• Current - Surge: 6 kA
• Number of Circuits: 1
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these core substitution criteria. Variations in secondary parameters such as package dimensions, energy rating, capacitance, and operating temperature range are documented to support engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

V14E150P (Littelfuse Inc.) is the primary substitute for the V14E150. Both parts are manufactured by Littelfuse Inc. within the UltraMOV™ series and share identical electrical specifications and package dimensions. The V14E150P is currently in active production status with significantly higher inventory availability (85,888 pcs vs. 1,091 pcs). Both parts carry ROHS3 compliance and identical operating temperature ranges (-55°C to 85°C). This substitute provides direct functional equivalence with no design modifications required.

ERZ-V14D241 (Panasonic Electronic Components) is a secondary substitute from an alternative manufacturer. This part meets all critical electrical parameters and maintains ROHS3 compliance. The ERZ-V14D241 offers higher energy rating (84 J vs. 60 J) and is available in active production status. Physical package dimensions differ slightly (Disc 15.5mm vs. Disc 14mm), and the operating temperature range is narrower (-40°C to 85°C vs. -55°C to 85°C). PCB layout verification is required to confirm mechanical fit before implementation.

Frequently Asked Questions (FAQ)

Q: Can V14E150P be used as a direct replacement for V14E150?

A: Yes. V14E150P is electrically and mechanically identical to V14E150. Both share the same varistor voltage specifications (240 V typical), surge current rating (6 kA), energy rating (60 J), and disc package dimensions (14mm). No circuit modifications are required.

Q: What are the key differences between V14E150P and ERZ-V14D241?

A: Both parts meet the core electrical requirements (240 V typical varistor voltage, 6 kA surge current, single circuit). Differences include: manufacturer (Littelfuse vs. Panasonic), package diameter (14mm vs. 15.5mm), energy rating (60 J vs. 84 J), operating temperature range (-55°C to 85°C vs. -40°C to 85°C), and capacitance measurement frequency (1 MHz vs. 1 kHz). The ERZ-V14D241 requires PCB layout verification due to package size variation.

Q: Why is the V14E150 listed as obsolete?

A: The V14E150 is no longer in active production. The V14E150P serves as the active production equivalent within the same manufacturer's product line.

Q: Are there any compliance differences between the substitute parts?

A: All three parts (V14E150, V14E150P, and ERZ-V14D241) are ROHS3 compliant. V14E150P and ERZ-V14D241 both carry REACH Unaffected status. All three share the same ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What should be verified before selecting ERZ-V14D241?

A: Verify PCB layout clearance for the larger 15.5mm disc package. Confirm that the narrower operating temperature range (-40°C to 85°C) is acceptable for the application. Validate that the higher energy rating (84 J) does not introduce unintended circuit behavior.
