Littelfuse V130LT5 Equivalent & Substitute Parts

Part Overview

The Littelfuse V130LT5 is a 205 V, 2.5 kA transient voltage suppressor (TVS) varistor in a 10mm disc form factor, designed for single-circuit through-hole applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. Active alternatives with identical electrical and mechanical specifications are available from Littelfuse across multiple packaging and series configurations.

Substitute Part Grouping Explanation

Substitution of the V130LT5 is determined by strict equivalence across all critical electrical and mechanical parameters. All substitute parts maintain identical varistor voltage specifications (184.5 V minimum to 225.5 V maximum, 205 V typical), surge current rating (2.5 kA), energy dissipation (20 J), capacitance (450 pF @ 1 MHz), operating temperature range (-55°C to 85°C), and physical form factor (10mm disc, through-hole mounting). The key differentiators among substitutes are product status (active vs. obsolete), packaging format (bulk, cut tape, or tape & reel), and internal series designation (LT, LS, LU). All substitute parts are manufactured by Littelfuse and maintain ROHS3 compliance and MSL 1 rating.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the V130LT5 and maintain full ROHS3 compliance and MSL 1 rating. Selection among substitutes should be based on procurement requirements and assembly process compatibility:

For manual assembly or low-volume applications, V130LS5P (cut tape packaging) offers the highest inventory availability at 5877 pieces. For automated assembly requiring tape & reel format, V130LT5P, V130LT5PX2855, V130LS5PX2855, V130LU5P, and V130LU5PX2855 are all suitable. The V130LT5PX2855 provides the highest inventory among tape & reel options at 1133 pieces while maintaining the same LT series designation as the original part. All active alternatives are currently in production and supported by Littelfuse.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the V130LT5?

A: Yes. All substitute parts maintain identical electrical specifications (205 V typical varistor voltage, 2.5 kA surge current, 20 J energy, 450 pF capacitance) and mechanical form factor (10mm disc, through-hole mounting). Substitution is valid across all listed parts.

Q: What is the difference between the various series designations (LT, LS, LU)?

A: The series designation (LT, LS, LU) represents internal Littelfuse product line classifications. All three series maintain identical electrical and mechanical parameters for this voltage and current rating. The series designation does not affect functional compatibility.

Q: Does packaging format affect electrical performance?

A: No. Bulk, cut tape, and tape & reel packaging formats contain identical components. Packaging selection is determined by assembly process requirements (manual vs. automated) and inventory management practices, not electrical performance.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited moisture sensitivity level) rating, matching the original V130LT5 specifications.

Q: Which substitute should I choose for new designs?

A: For new designs, select any active part from the substitute list. V130LS5P offers the highest inventory availability. For tape & reel automated assembly, V130LT5PX2855 provides good availability while maintaining the original LT series designation.
