Key Parameters

Substitute Part Grouping Explanation

The V510LC80BP has one parametric equivalent: V510LA80BP. This substitute relationship is established based on the following critical parameters that determine functional interchangeability:

• Varistor voltage range (Min: 738 V, Typ: 799 V, Max: 860 V)
• Surge current rating (6.5 kA)
• Maximum AC and DC voltage ratings (510 V AC, 675 V DC)
• Energy absorption capacity (190 J)
• Physical package form factor (Disc 20mm, through-hole mounting)
• Capacitance characteristics (500 pF @ 1 MHz)
• Operating temperature range (-55°C ~ 85°C)

Both parts belong to the Littelfuse varistor product line and differ only in their internal series designation (LC versus LA), while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both V510LC80BP and V510LA80BP are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts may be based on inventory availability: V510LC80BP has 936 units in stock, while V510LA80BP has 6961 units available. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. The choice between these equivalents does not impact circuit performance or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can V510LA80BP be used as a direct replacement for V510LC80BP?

A: Yes. Both parts share identical electrical specifications including varistor voltage (799 V typical), surge current rating (6.5 kA), energy absorption (190 J), and operating temperature range (-55°C to 85°C). The physical package (Disc 20mm through-hole) and mounting footprint are identical, enabling direct substitution without circuit modification.

Q: What determines the substitution relationship between these parts?

A: Substitution is based on matching critical parameters: varistor voltage range (738–860 V), surge current capacity (6.5 kA), maximum voltage ratings (510 V AC / 675 V DC), energy rating (190 J), package form factor (Disc 20mm), and operating temperature range (-55°C to 85°C). Both parts meet these criteria identically.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory status and environmental compliance are equivalent.

Q: What is the difference between the LC and LA series designations?

A: The LC and LA designations represent different internal series within the Littelfuse varistor product line. These designations do not reflect differences in electrical performance or mechanical specifications for these specific part numbers.

Q: Should inventory availability influence the selection?

A: Inventory levels may affect procurement timelines. V510LA80BP has higher stock availability (6961 units) compared to V510LC80BP (936 units). From an engineering standpoint, both parts are functionally equivalent and either may be selected based on supply chain requirements.
