V480LT40AP Equivalent & Substitute Parts

Part Overview

The V480LT40AP is a 750 V, 4.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the LT series. This through-hole disc varistor (14mm) is designed for transient voltage protection applications requiring high surge current capacity and energy absorption. The part is Active status and ROHS3 compliant, making it suitable for modern electronic equipment requiring environmental compliance. Substitute parts may be required due to packaging availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

The V480LS40AP qualifies as a parametric equivalent to the V480LT40AP based on the following substitution criteria:

Electrical Parameters (Identical):

• Maximum AC voltage: 480 V
• Maximum DC voltage: 640 V
• Varistor voltage range: 675–825 V (typical 750 V)
• Surge current capacity: 4.5 kA
• Energy absorption: 105 J
• Capacitance: 270 pF @ 1 MHz
• Operating temperature range: −55°C to +85°C
• Number of circuits: 1

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package / Case: Disc 14mm

Compliance & Status (Identical):

• RoHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

Packaging Difference:

• V480LT40AP: Tape & Reel (TR)
• V480LS40AP: Cut Tape (CT)

The substitution is valid because all electrical and mechanical specifications are identical. The packaging format difference (TR vs. CT) does not affect functional performance and represents a supply chain or procurement variant within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the V480LT40AP and V480LS40AP are Active status products from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

V480LT40AP (Tape & Reel): Suitable for high-volume automated assembly operations where tape and reel packaging provides efficient component feeding and handling.

V480LS40AP (Cut Tape): Suitable for lower-volume applications, manual assembly, or situations where cut tape packaging is preferred for inventory management or assembly line compatibility.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for modern electronic equipment. The MSL Rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either variant.

Frequently Asked Questions (FAQ)

Q: Can V480LS40AP replace V480LT40AP in my circuit design?

A: Yes. The V480LS40AP is electrically and mechanically identical to the V480LT40AP. All voltage ratings, surge current capacity, energy absorption, operating temperature range, and physical dimensions are equivalent. The only difference is packaging format (Cut Tape vs. Tape & Reel).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies the same components cut from the tape, typically for manual assembly or lower-volume applications. Both formats contain identical components with no functional difference.

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

A: No. Both V480LT40AP and V480LS40AP carry identical RoHS3 compliance, REACH unaffected status, and MSL Rating 1 (Unlimited). They are both Active status products from Littelfuse Inc.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes, provided your assembly process accommodates the packaging format. If your assembly line uses automated tape feeding, use the Tape & Reel variant (V480LT40AP). If your process uses cut tape or manual placement, either variant is suitable. The electrical and mechanical performance is identical.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: maximum AC/DC voltage ratings, varistor voltage range, surge current capacity, energy absorption, operating temperature range, mounting type, and physical package dimensions. Both parts match on all these criteria.
