V230LT10 Equivalent & Substitute Parts

Part Overview

The V230LT10 is a 360 V, 2.5 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance requirements. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the V230LT10 is determined by strict equivalence across all critical electrical and mechanical parameters. All substitute parts maintain identical varistor voltage specifications (324 V minimum, 360 V typical, 396 V maximum), surge current rating (2.5 kA), energy absorption (35 J), operating temperature range (-55°C to 85°C), and physical form factor (Disc 10mm through-hole package).

Substitute parts are grouped into two categories:

Direct Packaging Equivalent: V230LT10P differs only in packaging format (Tape & Reel versus bulk), maintaining the LT series designation and all electrical parameters.

Parametric Equivalents: V230LS10P, V230LS10PX2855, V230LT10PX2855, V230LU10P, and V230LU10PX2855 represent alternative series designations (LS and LU) with identical electrical specifications and physical dimensions. The "PX2855" suffix indicates Tape & Reel packaging with specific reel specifications.

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and supply chain continuity.

Engineering Selection Recommendations

For Direct Replacement: V230LT10P is the primary substitute, maintaining the LT series designation while transitioning from bulk to Tape & Reel packaging. This part is active and suitable for immediate procurement.

For Automated Assembly: V230LT10PX2855 and V230LS10PX2855 are specified for reel-based pick-and-place operations, with the PX2855 suffix indicating standardized reel configuration.

For Series Flexibility: V230LS10P, V230LS10PX2855, V230LU10P, and V230LU10PX2855 provide alternative series options (LS and LU) with identical electrical performance. These parts are active and REACH compliant, supporting long-term supply chain stability.

All substitute parts maintain ROHS3 compliance and are suitable for applications requiring regulatory adherence. Selection between packaging formats (standard Tape & Reel versus PX2855 reel specification) depends on assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can V230LT10P be used as a direct replacement for V230LT10?

A: Yes. V230LT10P is electrically and mechanically identical to V230LT10, differing only in packaging format (Tape & Reel versus bulk). The part is active and recommended for new designs and production.

Q: What is the difference between V230LT10P and V230LT10PX2855?

A: Both parts are electrically identical with 360 V varistor voltage and 2.5 kA surge current. The difference is in reel specification: V230LT10PX2855 includes the PX2855 reel designation for specific automated assembly equipment compatibility.

Q: Are LS and LU series parts fully compatible with the LT series?

A: Yes. V230LS10P, V230LS10PX2855, V230LU10P, and V230LU10PX2855 maintain identical electrical specifications (360 V typical varistor voltage, 2.5 kA surge current, 35 J energy) and physical dimensions (Disc 10mm through-hole). Series designation reflects internal design variations that do not affect circuit performance for this application.

Q: What packaging format should be selected for automated assembly?

A: Parts with "P" or "PX2855" designations are supplied in Tape & Reel format suitable for pick-and-place equipment. The PX2855 suffix specifies a particular reel configuration; verify compatibility with your assembly equipment before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronics manufacturing.
