V250LU10P Equivalent & Substitute Parts

Part Overview

The V250LU10P is a 390 V, 2.5 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant. The part is currently in active production status with 1039 units available in stock. Substitute parts become necessary when specific packaging formats (tape & reel versus cut tape) are required for manufacturing processes, or when inventory availability necessitates alternative sourcing from the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within this product family is determined by electrical parameter equivalence and mechanical compatibility. The V250LU10P, V250LS10P, and V250LT10P share identical electrical specifications: 390 V typical varistor voltage, 2.5 kA surge current, 40 J energy rating, and 220 pF capacitance at 1 MHz. All three parts maintain the same through-hole disc 10mm package format and operate within the identical temperature range of -55°C to 85°C.

The primary distinction between these parts lies in packaging format: V250LU10P is supplied in Tape & Reel (TR) configuration, while V250LS10P and V250LT10P are supplied in Cut Tape (CT) format. This difference affects manufacturing assembly processes but does not alter electrical performance or mechanical fit. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V250LU10P, V250LS10P, and V250LT10P—are electrically and mechanically equivalent for through-hole disc varistor applications requiring 390 V suppression at 2.5 kA surge capacity. Selection between these parts should be based on manufacturing assembly requirements and packaging availability.

V250LU10P in Tape & Reel format is suitable for automated pick-and-place assembly processes. V250LS10P and V250LT10P in Cut Tape format are appropriate for manual assembly or semi-automated processes where individual component handling is required.

All parts maintain active production status with Littelfuse Inc. and carry identical compliance certifications: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements for any of these variants.

Frequently Asked Questions (FAQ)

Q: Can V250LS10P or V250LT10P be used as direct replacements for V250LU10P in circuit design?

A: Yes. All three parts are electrically identical with matching varistor voltage (390 V typical), surge current (2.5 kA), energy rating (40 J), and operating temperature range (-55°C to 85°C). The only difference is packaging format, which does not affect electrical performance or circuit compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there any compliance or regulatory differences between these three parts?

A: No. V250LU10P, V250LS10P, and V250LT10P share identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 classified. Moisture sensitivity level is 1 (unlimited) for all variants.

Q: Which part should be selected based on current inventory?

A: V250LT10P has the highest inventory at 1753 units, followed by V250LS10P at 1235 units, and V250LU10P at 1039 units. Selection should prioritize manufacturing process requirements (packaging format) over inventory levels.

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. All three parts use identical through-hole disc 10mm package format and require the same PCB footprint and mounting procedure. Packaging format differences affect only the supply method, not the component installation.
