V230LS10 Equivalent & Substitute Parts

Part Overview

The Littelfuse V230LS10 is a 360 V, 2.5 kA disc varistor designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, which necessitates identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts ensure design continuity and procurement availability for applications requiring this varistor's performance characteristics.

Substitute Part Grouping Explanation

Substitution of the V230LS10 is determined by strict equivalence across all critical electrical and mechanical parameters. The allowed substitution criteria are:

Maximum AC Volts: 230 V
Maximum DC Volts: 300 V
Varistor Voltage (Typical): 360 V
Varistor Voltage Range: 324 V – 396 V
Current - Surge: 2.5 kA
Energy Rating: 35 J
Number of Circuits: 1
Capacitance @ 1 MHz: 250 pF
Operating Temperature Range: -55°C to 85°C

Engineering Selection Recommendations

All substitute parts are active products manufactured by Littelfuse Inc. and maintain full ROHS3 compliance. The V230LS10P and V230LS10PX2855 represent the primary substitutes, as they retain the LS series designation while offering active product status and improved procurement availability. The LT and LU series variants (V230LT10P, V230LT10PX2855, V230LU10P, V230LU10PX2855) are parametrically equivalent alternatives that provide additional inventory options.

Packaging format differences (bulk versus tape & reel) do not affect electrical or mechanical performance. Selection between standard tape & reel (P suffix) and extended tape & reel (PX2855 suffix) depends on assembly process requirements and procurement volume.

Frequently Asked Questions (FAQ)

Q: Can V230LS10 be directly replaced with V230LS10P? A: Yes. V230LS10P is electrically and mechanically identical to V230LS10. The primary difference is product status (active versus obsolete) and packaging format (tape & reel versus bulk). Both maintain the same 360 V varistor voltage, 2.5 kA surge current, and 10mm disc package.

Q: What is the difference between V230LS10P and V230LT10P? A: Both parts are parametrically equivalent with identical electrical specifications (230 V AC, 300 V DC, 360 V varistor voltage, 2.5 kA surge current, 35 J energy). The difference is the series designation (LS versus LT). Both are active products suitable for direct substitution.

Q: Are the PX2855 variants different from standard P variants? A: The PX2855 designation indicates extended tape & reel packaging. Electrical and mechanical specifications are identical to standard P variants. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Is the V230LS10 still available? A: The V230LS10 is classified as obsolete. Active equivalents (V230LS10P, V230LS10PX2855, V230LT10P, V230LT10PX2855, V230LU10P, V230LU10PX2855) are available for new designs and replacement applications.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). All are manufactured by Littelfuse Inc. and meet the same regulatory requirements.

Q: Can I mix different series (LS, LT, LU) in the same application? A: Yes. All three series maintain identical electrical and mechanical parameters for this voltage and current rating. Series selection does not affect circuit performance or compatibility.
