Key Parameters

Substitute Part Grouping Explanation

Substitution of the V480LU40AP is determined by equivalence across the following critical parameters:

• Voltage ratings: Maximum AC Volts (480 V), Maximum DC Volts (640 V), and Varistor Voltage range (675 V – 825 V)
• Surge current capacity: 4.5 kA
• Energy dissipation: 105 J
• Circuit configuration: Single circuit
• Electrical characteristics: Capacitance at 1 MHz (270 pF)
• Thermal performance: Operating temperature range (-55°C to 85°C)
• Physical form factor: Through-hole mounting, Disc 14mm package
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

The V480LS40AP meets all these criteria and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is packaging format: the V480LU40AP is supplied in Tape & Reel (TR), while the V480LS40AP is supplied in Cut Tape (CT).

Parameter Comparison

Engineering Selection Recommendations

Both the V480LU40AP and V480LS40AP are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts depends on procurement and assembly requirements:

The V480LU40AP in Tape & Reel format is suitable for high-volume automated assembly operations where reel-fed component handling is standard.

The V480LS40AP in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or situations where individual component access is required.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related constraints during inventory management.

Frequently Asked Questions (FAQ)

Q: Can V480LS40AP replace V480LU40AP in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Cut Tape. Substitution is valid provided the assembly process can accommodate the different packaging format.

Q: Are there any performance differences between these parts?

A: No. Electrical specifications, thermal characteristics, surge current capacity, and energy ratings are identical across both part numbers.

Q: What does the packaging format difference mean for my application?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides individual component access and is typically used for manual assembly or lower-volume production.

Q: Do both parts meet the same compliance standards?

A: Yes. Both V480LU40AP and V480LS40AP are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating.

Q: Can I mix these parts in the same design?

A: Yes. Since electrical and mechanical specifications are identical, both parts can be used interchangeably within the same circuit design without any functional impact.
