V14P250PL2B Equivalent & Substitute Parts

Part Overview

The V14P250PL2B is a 390 V, 6 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse 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 and fully compliant with RoHS3 and REACH regulations. Alternative equivalent parts may be required due to inventory availability, supply chain considerations, or specific application requirements for thermal protection features.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the V14P250PL2B is determined by strict alignment of electrical and mechanical parameters. The critical substitution criteria are:

• Varistor voltage rating (typical value 390 V, range 351 V – 429 V)
• Surge current capacity (6 kA)
• Energy absorption capability (100 J)
• Mounting configuration (Through Hole, Disc 14mm package)
• Operating temperature range (-55°C to 85°C)
• Regulatory compliance (RoHS3, REACH Unaffected)

Both identified substitute parts meet all these parameters. The TMOV14RP250E variant includes thermally protected construction, which represents an enhanced feature set within the same electrical specification envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V14P250PL2B, V14E250P, and TMOV14RP250E—are functionally equivalent for 390 V transient voltage suppression applications. Selection between them should be based on:

• Product availability and inventory status
• Series preference (UltraMOV™ vs. TMOV®)
• Thermal protection requirement (TMOV14RP250E includes thermally protected construction)
• All parts maintain Active product status and full RoHS3 and REACH compliance

Direct pin-for-pin and footprint compatibility is confirmed across all three parts due to identical through-hole disc 14mm packaging.

Frequently Asked Questions (FAQ)

Q: Can V14E250P be used as a direct replacement for V14P250PL2B?

A: Yes. Both parts share identical electrical specifications (390 V typical varistor voltage, 6 kA surge current, 100 J energy), operating temperature range, and through-hole disc 14mm package configuration. Both are UltraMOV™ series components with Active product status and RoHS3 compliance.

Q: What is the difference between TMOV14RP250E and V14P250PL2B?

A: The TMOV14RP250E is electrically and mechanically equivalent but belongs to the TMOV® series and includes thermally protected construction. All electrical parameters, package type, and compliance certifications are identical.

Q: Are these parts interchangeable in PCB designs?

A: Yes. All three parts use identical through-hole disc 14mm packaging and mounting configuration, confirming direct PCB footprint compatibility.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. V14P250PL2B, V14E250P, and TMOV14RP250E are all RoHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What determines whether a part qualifies as an equivalent substitute?

A: Equivalence is determined by matching varistor voltage rating (390 V typical), surge current capacity (6 kA), energy absorption (100 J), operating temperature range (-55°C to 85°C), and physical package (through-hole disc 14mm). All three parts meet these criteria.
