V100MA4S Equivalent & Substitute Parts

Part Overview

The V100MA4S is a 100 V, 40 A varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component operates across a temperature range of -55°C to 85°C and is packaged in SOD-83A axial configuration. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V100MA4S is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

• Varistor voltage rating (minimum, typical, and maximum values must match: 90 V / 100 V / 110 V)
• Surge current capacity (40 A minimum)
• Package and mounting configuration (SOD-83A Axial, through-hole)
• Operating temperature range (-55°C to 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The V100MA4B meets all substitution criteria and is classified as a manufacturer-recommended equivalent. Minor variations in energy rating (0.45 J vs. 0.42 J) remain within acceptable tolerance for this component category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V100MA4S and V100MA4B are active production components with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on availability and inventory status. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental and hazardous substance certifications. The marginal energy rating difference (0.42 J vs. 0.45 J) does not impact circuit performance or thermal management requirements for standard transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can V100MA4B be used as a direct replacement for V100MA4S?

A: Yes. Both parts share identical varistor voltage ratings (90 V / 100 V / 110 V), surge current capacity (40 A), package configuration (SOD-83A Axial), and operating temperature range (-55°C to 85°C). They are functionally equivalent for through-hole circuit applications.

Q: What is the significance of the energy rating difference between these parts?

A: The energy rating difference (0.42 J vs. 0.45 J) reflects minor manufacturing variations within the MA series. This difference does not affect transient suppression performance or thermal characteristics in standard applications.

Q: Are both parts suitable for high-temperature applications?

A: Both the V100MA4S and V100MA4B operate across the same temperature range of -55°C to 85°C. Selection should be based on specific application thermal requirements within this range.

Q: Do these parts require any special handling or storage considerations?

A: Both components carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard electronic component handling practices apply.

Q: Are there any compliance differences between V100MA4S and V100MA4B?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications. They are suitable for applications requiring environmental compliance documentation.
