Substitute Part Grouping Explanation

Substitute parts for the V130LS1 are classified based on the following substitution criteria:

Direct Manufacturer Substitutes: Parts that maintain identical electrical parameters, mechanical form factor, and through-hole mounting configuration. These parts differ only in packaging format (Tape & Reel vs. bulk) or internal series designation.

Parametric Equivalents: Parts that match all critical electrical specifications (voltage ratings, surge current, energy rating, capacitance) and mechanical requirements (Disc 7mm package, through-hole mounting) while belonging to different product series within the Littelfuse varistor portfolio.

Key Parameters Determining Substitutability:

Varistor voltage range (198 V – 242 V)
Surge current rating (1.2 kA)
Energy dissipation (11 J)
Package form factor (Disc 7mm)
Mounting type (Through Hole)
Operating temperature range (-55°C to 85°C)

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to the V130LS1 across all critical electrical and mechanical specifications. Selection among substitutes should be based on the following factors:

Product Status: V130LS1P, V130LS1PX2855, V130LT1P, V130LT1PX2855, V130LU1P, and V130LU1PX2855 are all classified as active products, ensuring long-term availability and supply chain stability compared to the obsolete V130LS1.

Packaging Format: Parts designated with "P" suffix are supplied in Tape & Reel packaging, suitable for automated assembly processes. The X2855 designation indicates specific reel configuration. Bulk packaging is no longer available for active equivalents.

Compliance: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.

Series Designation: The LS, LT, and LU series designations represent different product lines within Littelfuse's varistor portfolio. All three series maintain identical electrical performance for this voltage and current rating.

Frequently Asked Questions (FAQ)

Q: Can V130LS1P be used as a direct replacement for V130LS1? A: Yes. V130LS1P is the active equivalent of the obsolete V130LS1, maintaining identical electrical parameters and Disc 7mm through-hole package. The primary difference is packaging format (Tape & Reel vs. bulk) and active product status.

Q: What is the difference between V130LS1P and V130LT1P? A: Both parts are parametrically equivalent with identical electrical specifications (220 V varistor voltage, 1.2 kA surge current, 11 J energy). The difference is the product series designation (LS vs. LT). Both are suitable for the same application requirements.

Q: Does the X2855 designation affect electrical performance? A: No. The X2855 designation specifies the reel configuration for Tape & Reel packaging. Electrical and mechanical specifications remain identical to the non-X2855 variant.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental standards of the original V130LS1.

Q: Can I use these parts interchangeably in existing designs? A: Yes, provided your design accommodates Tape & Reel packaging format. All substitute parts maintain the same Disc 7mm through-hole package and electrical specifications, ensuring direct functional compatibility.

Q: What is the operating temperature range for all substitute parts? A: All substitute parts operate across -55°C to 85°C, matching the original V130LS1 specification.
