Key Parameters

Substitute Part Grouping Explanation

The V480LS80BP is classified as a parametric equivalent to the V480LU80BP based on the following substitution criteria:

Electrical Parameters (Identical):

• Maximum AC Volts: 480 V
• Maximum DC Volts: 640 V
• Varistor Voltage (Typical): 732.5 V
• Varistor Voltage Range: 675–790 V
• Current - Surge: 6.5 kA
• Energy Absorption: 180 J
• Capacitance @ 1 MHz: 550 pF

Mechanical Parameters (Identical):

• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• Number of Circuits: 1

Compliance & Environmental (Identical):

• Operating Temperature Range: −55°C to +85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary difference between V480LU80BP and V480LS80BP is the series designation (LU vs. LS), which reflects internal design variations within Littelfuse's product line while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both V480LU80BP and V480LS80BP are active production components from Littelfuse Inc. with identical electrical specifications and mechanical form factors. Selection between these parts may be based on:

Availability: Current inventory levels differ (V480LU80BP: 623 pcs; V480LS80BP: 752 pcs). Supply chain considerations may favor the LS variant where stock is higher.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Series Designation: The LU and LS series designations represent internal Littelfuse product line variations. Both are qualified for identical circuit protection applications within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can V480LS80BP directly replace V480LU80BP in existing designs?

A: Yes. Both parts share identical electrical parameters (732.5 V typical varistor voltage, 6.5 kA surge current, 180 J energy), mechanical packaging (through-hole disc 20mm), and operating temperature range (−55°C to +85°C). No circuit redesign is required.

Q: Are there any differences in surge current handling between these parts?

A: No. Both V480LU80BP and V480LS80BP are rated for 6.5 kA surge current with 180 J energy absorption capacity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the LU and LS series designations?

A: LU and LS represent different series within Littelfuse's varistor product line. These designations reflect internal design variations but do not affect electrical performance or mechanical compatibility for applications requiring 732.5 V protection at 6.5 kA surge capacity.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use identical through-hole mounting with 20mm disc packaging, allowing direct PCB footprint compatibility without layout modifications.
