V150LU2P Equivalent & Substitute Parts

Part Overview

The V150LU2P is a 240 V, 1.2 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component is classified as Active and maintains full product support. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences.

Substitute Part Grouping Explanation

Substitution eligibility for the V150LU2P is determined by the following critical parameters:

Varistor Voltage (Typical): 240 V nominal
Varistor Voltage Range: 216–264 V (minimum to maximum)
Current - Surge Rating: 1.2 kA
Mounting Type: Through Hole
Package / Case: Disc 7mm
Number of Circuits: 1
RoHS Compliance: ROHS3 Compliant

All identified substitutes maintain these core electrical and mechanical specifications. Variations in packaging format (Tape & Reel versus Cut Tape), manufacturer series designation, and minor differences in secondary parameters (capacitance measurement frequency, energy rating, operating temperature range) do not affect functional equivalence within the defined application scope.

Engineering Selection Recommendations

Littelfuse V150LS2P and V150LT2P: These parts are parametric equivalents to the V150LU2P, differing only in packaging format and internal series designation. Both maintain identical electrical specifications and operating temperature range. Selection between these Littelfuse variants depends on procurement requirements: V150LU2P is supplied in Tape & Reel format, while V150LS2P and V150LT2P are supplied in Cut Tape format. All three are Active products with ROHS3 compliance and REACH Unaffected status.

EPCOS B72207S0151K111: This part is a manufacturer-recommended equivalent from EPCOS - TDK Electronics. It maintains all critical electrical parameters (varistor voltage, surge current, circuit count, mounting type, and package geometry). The operating temperature range extends to +105°C compared to +85°C for Littelfuse variants, providing enhanced thermal performance in high-temperature environments. Energy rating is specified as 11 J versus 13 J for Littelfuse parts. Capacitance measurement frequency differs (210 pF @ 1 kHz versus 150 pF @ 1 MHz), reflecting different measurement methodologies rather than functional incompatibility. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent.

Frequently Asked Questions (FAQ)

Q: Can V150LS2P or V150LT2P be used as direct replacements for V150LU2P?

A: Yes. These parts are parametric equivalents with identical electrical performance and mechanical compatibility. The only difference is packaging format: V150LU2P is supplied in Tape & Reel, while V150LS2P and V150LT2P are supplied in Cut Tape. All three are suitable for the same through-hole applications.

Q: What is the difference between the Littelfuse and EPCOS variants?

A: The EPCOS B72207S0151K111 maintains all critical electrical specifications required for substitution. The extended operating temperature range (−40 to +105°C versus −55 to +85°C) makes it suitable for applications requiring higher thermal tolerance. Energy rating and capacitance measurement frequency reflect manufacturer-specific characterization methods and do not affect functional equivalence.

Q: Are there any compatibility concerns when switching between these substitutes?

A: No compatibility concerns exist for applications within the specified electrical and thermal parameters. All substitutes are through-hole mounted in identical Disc 7mm packages and maintain the same varistor voltage range, surge current rating, and circuit count. PCB layout and lead spacing are compatible across all variants.

Q: Which substitute should be selected for high-temperature applications?

A: The EPCOS B72207S0151K111 is suitable for operating temperatures up to +105°C, compared to +85°C maximum for Littelfuse variants. Selection depends on application thermal requirements.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All identified substitutes (V150LS2P, V150LT2P, and B72207S0151K111) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the V150LU2P.
