V510LC10P Equivalent & Substitute Parts

Part Overview

The V510LC10P is a 820 V, 2.5 kA disc varistor manufactured by Littelfuse in the LC series. This transient voltage suppressor is designed for through-hole mounting applications requiring overvoltage protection in a 10mm disc package format. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent substitute parts are identified based on matching electrical performance specifications and mechanical compatibility within the same product category.

Key Parameters

Substitute Part Grouping Explanation

The V510LA10P qualifies as a parametric equivalent to the V510LC10P based on the following matching criteria:

• Identical varistor voltage range: 738 V (Min) to 902 V (Max), with 820 V typical
• Identical surge current rating: 2.5 kA
• Identical maximum AC and DC voltage ratings: 510 V AC / 675 V DC
• Identical energy dissipation: 63 J
• Identical package format: Disc 10mm through-hole
• Identical capacitance specification: 100 pF @ 1 MHz
• Identical operating temperature range: -55°C to 85°C
• Identical compliance certifications: RoHS3, REACH Unaffected, MSL 1

The primary difference between these parts is the series designation (LC versus LA), which reflects internal design variations within Littelfuse's varistor product line while maintaining full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the V510LC10P and V510LA10P are active production parts with identical electrical specifications and mechanical compatibility. Selection between these parts may be based on availability and supply chain considerations. The V510LA10P currently maintains higher inventory levels (14,645 pcs) compared to the V510LC10P (965 pcs). Both parts meet RoHS3 compliance requirements and carry REACH Unaffected status, making them suitable for regulated applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can V510LA10P be used as a direct replacement for V510LC10P?

A: Yes. Both parts share identical electrical ratings (820 V typical varistor voltage, 2.5 kA surge current), identical mechanical packaging (Disc 10mm through-hole), and identical compliance certifications. The series designation difference (LC versus LA) does not affect functional interchangeability.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both the V510LC10P and V510LA10P operate across the identical temperature range of -55°C to 85°C.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: What is the significance of the series designation (LC versus LA)?

A: The series designation reflects internal design variations within Littelfuse's varistor product line. These variations do not affect the electrical performance or mechanical compatibility of the parts when used in applications requiring 820 V, 2.5 kA transient voltage suppression.

Q: Are both parts RoHS compliant?

A: Yes. Both the V510LC10P and V510LA10P are ROHS3 Compliant and carry REACH Unaffected status.
