V150CH8 Equivalent & Substitute Parts

Part Overview

The V150CH8 is a 150 V, 250 A Varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in surface mount applications. This component operates across a temperature range of -40°C to 125°C and is packaged in a 2-SMD, No Lead configuration. The part is currently Active in product status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this transient voltage suppressor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V150CH8 is determined by the following critical parameters:

• Varistor Voltage (Typ): Must be 150 V
• Varistor Voltage Range: Must fall within 135–165 V
• Maximum AC Volts: Must be 95 V or greater
• Maximum DC Volts: Must be 127 V or greater
• Number of Circuits: Must be 1
• Mounting Type: Must be Surface Mount, MLCV
• RoHS Status: Must be ROHS3 Compliant

The V150CH8T qualifies as a parametric equivalent under these criteria. The B72660M0950K072 qualifies as a manufacturer-recommended alternative, though it exhibits differences in surge current capacity, energy rating, and operating temperature maximum that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The V150CH8T is a direct parametric equivalent to the V150CH8, sharing identical electrical specifications, operating temperature range, and package configuration. Both parts are manufactured by Littelfuse Inc., maintain Active product status, and carry ROHS3 compliance. Selection between these two parts may be based on inventory availability or supply chain considerations.

The B72660M0950K072, manufactured by EPCOS - TDK Electronics, is designated as a manufacturer-recommended alternative. This part maintains the core voltage suppression characteristics (150 V typical varistor voltage) and meets the maximum AC and DC voltage requirements. However, the following differences apply:

• Surge current capacity is 1.2 kA versus 250 A in the main part
• Energy rating is 7.6 J versus 3 J
• Maximum operating temperature is 85°C versus 125°C
• Package footprint is 4032 (10080 Metric) versus 2-SMD, No Lead
• Packaging format is Cut Tape versus Tape & Reel

All three parts maintain ROHS3 compliance and Active product status. Selection of the B72660M0950K072 requires confirmation that the application can accommodate the larger package footprint and that the reduced maximum operating temperature (85°C) is acceptable for the intended thermal environment.

Frequently Asked Questions (FAQ)

Q: Can the V150CH8T be used as a direct replacement for the V150CH8?

A: Yes. The V150CH8T is a parametric equivalent with identical electrical specifications, operating temperature range (-40°C to 125°C), and 2-SMD, No Lead package configuration. Both parts are manufactured by Littelfuse Inc. and carry ROHS3 compliance.

Q: What are the key differences between the V150CH8 and the B72660M0950K072?

A: The B72660M0950K072 differs in three primary areas: (1) Surge current capacity is 1.2 kA compared to 250 A; (2) Energy rating is 7.6 J compared to 3 J; (3) Maximum operating temperature is 85°C compared to 125°C. Additionally, the package footprint is 4032 (10080 Metric) rather than 2-SMD, No Lead, requiring PCB layout modification.

Q: Is the B72660M0950K072 suitable for applications requiring operation above 85°C?

A: No. The B72660M0950K072 has a maximum operating temperature of 85°C. Applications requiring operation up to 125°C must use the V150CH8 or V150CH8T.

Q: Can the B72660M0950K072 be used in a circuit designed for the V150CH8?

A: Electrical compatibility exists for the core voltage suppression function, as both parts maintain a 150 V typical varistor voltage and meet the maximum AC and DC voltage requirements. However, physical compatibility requires verification: the B72660M0950K072 uses a 4032 (10080 Metric) package footprint, which differs from the 2-SMD, No Lead configuration of the V150CH8. PCB layout modification is necessary.

Q: Are all three parts RoHS compliant?

A: Yes. The V150CH8, V150CH8T, and B72660M0950K072 are all ROHS3 compliant.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on tape segments, typically used for lower-volume applications or manual assembly. The V150CH8 and V150CH8T are supplied in Tape & Reel format; the B72660M0950K072 is supplied in Cut Tape format.
