V150LA5 Equivalent & Substitute Parts

Part Overview

The V150LA5 is a 240 V, 2.5 kA varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole disc configurations. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The V150LA5P serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved availability and active product support.

Key Parameters

Substitute Part Grouping Explanation

The V150LA5P qualifies as a direct substitute for the V150LA5 based on strict equivalence across all critical electrical and mechanical parameters. Substitution is valid when the following conditions are met:

• Maximum AC voltage rating: 150 V
• Maximum DC voltage rating: 200 V
• Varistor voltage (typical): 240 V
• Surge current capacity: 2.5 kA
• Energy dissipation: 25 J
• Package configuration: Through hole disc 10mm
• Operating temperature range: -55°C to 85°C
• Number of circuits: 1

The V150LA5P maintains 100% electrical and mechanical compatibility with the original V150LA5 specification, with the primary distinction being product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The V150LA5P is the appropriate selection for applications currently specified with the V150LA5. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status and improved supply chain availability. Both components are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000), ensuring compliance continuity in regulated applications.

For new designs and production continuity, the V150LA5P should be specified in place of the obsolete V150LA5. No circuit redesign or validation is required when transitioning between these parts, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the V150LA5P be used as a direct replacement for the V150LA5?

A: Yes. The V150LA5P is electrically and mechanically identical to the V150LA5 across all specified parameters, including voltage ratings, surge current capacity, energy dissipation, and package configuration. Direct substitution is valid without circuit modification.

Q: What is the primary difference between the V150LA5 and V150LA5P?

A: The V150LA5 is classified as obsolete, while the V150LA5P maintains active product status. The V150LA5P also differs in packaging format (bulk versus standard), but electrical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant with identical regulatory classifications. Compliance status remains unchanged when substituting the V150LA5P for the V150LA5.

Q: What mounting configuration do these varistors use?

A: Both the V150LA5 and V150LA5P are through-hole mounted components in a 10mm disc package, suitable for PCB insertion and wave soldering processes.

Q: What is the operating temperature range for these components?

A: Both parts operate across the temperature range of -55°C to 85°C, providing consistent performance across industrial and commercial applications.
