Key Parameters

Substitute Part Grouping Explanation

The V300LS10P qualifies as a parametric equivalent to the V300LU10P based on the following criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 423 V (Min) to 517 V (Max), with 470 V typical
• Surge current capacity: 2.5 kA
• Maximum AC/DC voltage ratings: 300 V AC / 405 V DC
• Energy dissipation: 46 J
• Capacitance: 180 pF @ 1 MHz

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package form: Disc 10mm
• Number of circuits: 1

Variation:

• Packaging format: V300LU10P supplied in Tape & Reel (TR); V300LS10P supplied in Cut Tape (CT)

The packaging difference does not affect electrical performance or mechanical compatibility. Both parts belong to the Littelfuse LU/LS series and maintain active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the V300LU10P and V300LS10P are active products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts depends on procurement and assembly requirements:

V300LU10P (Tape & Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging integrates directly with pick-and-place equipment.

V300LS10P (Cut Tape): Suitable for lower-volume applications, manual assembly, or situations where smaller quantity increments are required.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility across applications. The choice between packaging formats does not compromise electrical performance, thermal characteristics, or surge current handling capacity.

Frequently Asked Questions (FAQ)

Q: Can V300LS10P replace V300LU10P in existing designs? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Reel). No circuit redesign or re-qualification is required.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume orders.

Q: Are both parts ROHS3 compliant? A: Yes. Both V300LU10P and V300LS10P are ROHS3 compliant and REACH unaffected.

Q: Do these parts have the same operating temperature range? A: Yes. Both parts operate from -55°C to 85°C (TA).

Q: What is the surge current capacity of these varistors? A: Both parts handle 2.5 kA surge current with 46 J energy dissipation.

Q: Can these parts be used interchangeably in PCB assembly? A: Yes, provided the assembly process accommodates the packaging format. Tape & Reel requires automated equipment; Cut Tape is compatible with manual or semi-automated processes.
