V575LA10 Equivalent & Substitute Parts

Part Overview

The V575LA10 is a 910 V, 2.5 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The varistor provides protection against voltage transients with a 10mm disc form factor and operates across a temperature range of -55°C to 85°C.

Substitute Part Grouping Explanation

Substitution for the V575LA10 is based on electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

Varistor voltage range: 819 V (Min) to 1.001 kV (Max), with 910 V typical
Surge current capacity: 2.5 kA
Maximum AC and DC voltage ratings: 575 V AC / 730 V DC
Energy dissipation: 65 J
Physical form factor: Disc 10mm through-hole mounting
Operating temperature range: -55°C to 85°C
Capacitance: 90 pF @ 1 MHz
Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The substitute parts are grouped into two series variants (LA and LC) with identical electrical performance. Packaging differences (Bulk) and product status variations (Active vs. Obsolete) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All substitute parts are electrically and mechanically equivalent to the V575LA10. Selection should prioritize active product status parts to ensure long-term availability and supply chain continuity.

V575LA10P is the direct successor within the LA series and maintains identical electrical characteristics with active product status and highest inventory availability (6026 Pcs). This part is the primary recommendation for direct replacement.

V575LC10P and V575LC10PX2855 represent the LC series equivalent, offering identical electrical performance with active status. These parts are suitable for applications where series designation does not impose design constraints.

All substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Packaging is standardized as Bulk across all active variants.

Frequently Asked Questions (FAQ)

Q: Can V575LA10P directly replace V575LA10? A: Yes. V575LA10P is electrically and mechanically identical to V575LA10, with the primary difference being active product status and bulk packaging. Both maintain 910 V typical varistor voltage, 2.5 kA surge current, and disc 10mm form factor.

Q: What is the difference between LA and LC series variants? A: LA and LC series variants are parametrically equivalent for this voltage and current rating. Both series maintain identical electrical specifications: 910 V typical varistor voltage, 2.5 kA surge current, 65 J energy, and disc 10mm mounting. Series designation does not affect functional compatibility.

Q: Are the X2855 suffix variants compatible? A: Yes. V575LA10PX2855 and V575LC10PX2855 are parametrically equivalent to their non-suffixed counterparts. The X2855 suffix indicates a specific manufacturing or traceability designation but does not alter electrical or mechanical performance.

Q: What is the significance of product status (Active vs. Obsolete)? A: Active status indicates ongoing manufacturing and supply availability. Obsolete status indicates discontinued production. For new designs or long-term procurement, active parts (V575LA10P, V575LA10PX2855, V575LC10P, V575LC10PX2855) are recommended to ensure sustained component availability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements.

Q: Does packaging type affect electrical performance? A: No. Bulk packaging does not affect electrical or mechanical performance. Packaging differences relate only to order quantity and handling, not component functionality.
