V575LS40APX2855 Equivalent & Substitute Parts

Part Overview

The V575LS40APX2855 is a 910 V, 4.5 kA disc varistor manufactured by Littelfuse in the LS series. This transient voltage suppressor is designed for single-circuit through-hole applications with a 14mm disc package. The component is ROHS3 compliant and rated for operating temperatures from -55°C to 85°C. As an active product with current inventory availability, substitute parts may be required due to packaging format preferences, supply chain optimization, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V575LS40APX2855 is determined by strict equivalence across the following critical parameters:

• Varistor voltage range (Min: 819 V, Typ: 910 V, Max: 1.001 kV)
• Surge current rating (4.5 kA)
• Maximum AC and DC voltage ratings (575 V AC, 730 V DC)
• Energy dissipation capacity (120 J)
• Capacitance specification (220 pF @ 1 MHz)
• Operating temperature range (-55°C to 85°C)
• Through-hole mounting configuration
• Disc 14mm package geometry
• Single-circuit design

All identified substitute parts maintain identical electrical and mechanical specifications. Differences are limited to packaging format (tape & reel versus cut tape) and series designation, which do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between V575LS40APX2855, V575LS40AP, and V575LT40AP should be based on packaging format requirements and supply chain availability.

V575LS40APX2855 and V575LS40AP are both supplied in tape & reel format, suitable for automated assembly processes. V575LT40AP is supplied in cut tape format, appropriate for manual assembly or lower-volume applications. The series designation difference (LS versus LT) reflects packaging methodology only and does not affect electrical performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can V575LS40AP be used as a direct replacement for V575LS40APX2855?

A: Yes. Both parts are identical in electrical specifications, varistor voltage range, surge current rating, and physical package dimensions. The difference is limited to packaging format (both are tape & reel), making them functionally interchangeable.

Q: What is the difference between V575LT40AP and the LS series parts?

A: V575LT40AP maintains identical electrical and mechanical specifications. The primary difference is packaging format: V575LT40AP is supplied in cut tape (CT) rather than tape & reel (TR). This affects handling and assembly methodology but not component performance.

Q: Are all three parts suitable for the same circuit application?

A: Yes. All three parts share identical varistor voltage ratings (910 V typical), surge current capacity (4.5 kA), energy dissipation (120 J), and operating temperature range (-55°C to 85°C). They are electrically and mechanically equivalent for circuit design purposes.

Q: Does packaging format affect the component's electrical performance?

A: No. Packaging format (tape & reel versus cut tape) is a supply and assembly consideration only. It does not alter the electrical characteristics, voltage ratings, or surge current handling capability of the varistor.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. V575LS40APX2855, V575LS40AP, and V575LT40AP are all ROHS3 compliant with MSL rating 1 (unlimited) and REACH unaffected status.
