Equivalent & Substitute Parts for V14P300P

Part Overview

The V14P300P is a 470 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 Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category, enabling component interchangeability in circuit designs where the original part number may have limited availability or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V14P300P are qualified based on the following critical parameters that determine functional interchangeability:

• Maximum AC Volts: 300 V
• Maximum DC Volts: 385 V
• Varistor Voltage (Typ): 470 V
• Current - Surge: 6 kA
• Energy: 125 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• Operating Temperature Range: -55°C ~ 85°C

All identified substitute parts maintain identical values across these parameters. Substitutes may originate from different product series within Littelfuse Inc. (such as TMOV® series) or include variants with additional features (such as thermal protection), provided the core electrical and mechanical specifications remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V14P300P, TMOV14RP300E, and V14E300P—are Active status components manufactured by Littelfuse Inc. and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and series preference:

V14P300P and V14E300P are both UltraMOV™ series components with identical electrical and mechanical specifications. TMOV14RP300E is from the TMOV® series and includes thermal protection as an additional feature while maintaining all core parameter equivalence. All three parts are suitable for direct substitution in circuit applications requiring 470 V, 6 kA transient voltage suppression in a 14mm through-hole disc package.

Frequently Asked Questions (FAQ)

Q: Can TMOV14RP300E replace V14P300P directly in a circuit? A: Yes. TMOV14RP300E maintains identical electrical parameters (470 V typical varistor voltage, 6 kA surge current, 125 J energy) and mechanical specifications (14mm disc, through-hole mounting). The addition of thermal protection in the TMOV® series does not affect functional interchangeability.

Q: What is the difference between V14P300P and V14E300P? A: Both parts are UltraMOV™ series components with identical electrical and mechanical specifications. The difference is in part number designation only; they are functionally equivalent for circuit applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. V14P300P, TMOV14RP300E, and V14E300P are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. All three parts share the same through-hole disc 14mm package and mounting type, enabling direct PCB footprint compatibility without design modification.

Q: What operating temperature range applies to all substitute parts? A: All parts operate within -55°C to 85°C ambient temperature range, maintaining consistent thermal performance across the substitute group.
