Littelfuse V230LA10 Varistor: Equivalent & Substitute Parts

Part Overview

The Littelfuse V230LA10 is a 360 V, 2.5 kA disc varistor designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The V230LA10 operates across a temperature range of -55°C to 85°C and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute Part Grouping Explanation

Substitution for the V230LA10 is based on electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

Maximum AC/DC voltage ratings (230 V AC, 300 V DC)
Varistor voltage range (324 V – 396 V)
Surge current capacity (2.5 kA)
Energy absorption (35 J)
Capacitance at 1 MHz (250 pF)
Operating temperature range (-55°C to 85°C)
Through-hole mounting with 10mm disc package
ROHS3 compliance

Substitute parts are grouped into two categories: direct manufacturer equivalents (same series designation) and parametric equivalents (different series designation but identical electrical performance).

Engineering Selection Recommendations

All substitute parts listed are active products from Littelfuse Inc., providing continuity for designs currently using the obsolete V230LA10. Selection among substitutes should prioritize active product status and availability:

V230LA10P and V230LA10PX2855 maintain the LA series designation and represent the direct replacement path for the V230LA10. V230LA10P offers the highest inventory availability (5080 units) with bulk packaging.

V230LC10P and V230LC10PX2855 are parametric equivalents from the LC series. These parts deliver identical electrical performance and mechanical compatibility while offering alternative sourcing options. V230LC10PX2855 provides the largest inventory reserve (1129 units).

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Packaging designations (bulk) differ from the original part but do not affect functional performance in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can V230LC10P replace V230LA10 directly? A: Yes. V230LC10P is a parametric equivalent with identical electrical specifications (360 V typical varistor voltage, 2.5 kA surge current, 35 J energy) and mechanical compatibility (through-hole, 10mm disc package). The series designation change (LC vs. LA) does not affect performance in applications requiring these specifications.

Q: What is the difference between V230LA10P and V230LA10PX2855? A: Both parts are LA series equivalents with identical electrical and mechanical parameters. The X2855 suffix indicates a specific manufacturing or packaging variant. Both are active products suitable for direct substitution of the obsolete V230LA10.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (V230LA10P, V230LA10PX2855, V230LC10P, V230LC10PX2855) are ROHS3 compliant with REACH unaffected status.

Q: Does packaging type affect substitution compatibility? A: The original V230LA10 uses standard packaging, while all substitutes are supplied in bulk packaging. This designation reflects supply format only and does not impact electrical performance or through-hole mounting compatibility in PCB applications.

Q: Which substitute offers the best availability? A: V230LA10P provides the highest inventory level at 5080 units, followed by V230LC10PX2855 at 1129 units. Both are active products suitable for immediate procurement.
