Substitute Part Grouping Explanation

Substitute parts for the V230LS20A are qualified based on strict electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

Maximum AC and DC voltage ratings (230 V AC / 300 V DC)
Varistor voltage range (324 V – 396 V, typical 360 V)
Surge current capacity (4.5 kA)
Energy absorption capability (70 J)
Single-circuit configuration
Capacitance value (550 pF @ 1 MHz)
Operating temperature range (-55°C to 85°C)
Through-hole mounting with 14mm disc package
ROHS3 compliance and MSL 1 rating

Substitutes differ only in series designation (LS, LT, LU) and packaging variant (standard TR or X2855 reel configuration), with no impact on electrical performance or mechanical compatibility.

Engineering Selection Recommendations

All substitute parts are manufactured by Littelfuse Inc. and carry active product status, ensuring long-term availability and supply chain continuity. Each substitute maintains ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements equivalent to the original V230LS20A.

Selection between substitute options should be based on:

Inventory availability and lead time requirements
Packaging preference (standard tape & reel versus X2855 reel configuration)
Series designation compatibility with existing bill of materials documentation
Supply chain logistics and procurement channels

All listed substitutes are electrically and mechanically interchangeable with the V230LS20A in through-hole circuit applications requiring 360 V varistor protection with 4.5 kA surge capacity.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to the V230LS20A?

A: Yes. All substitute parts maintain identical electrical specifications including varistor voltage (360 V typical), surge current rating (4.5 kA), energy absorption (70 J), and operating temperature range (-55°C to 85°C). They are direct functional equivalents.

Q: What is the difference between LS, LT, and LU series designations?

A: Series designations represent different product lines within Littelfuse's varistor portfolio. All three series maintain identical electrical and mechanical parameters for this voltage and current rating. Selection between series is based on design documentation requirements and supply availability.

Q: What does the X2855 suffix indicate?

A: The X2855 suffix identifies a specific reel configuration for tape & reel packaging. Parts with and without this suffix are electrically equivalent; the difference is packaging format only. Selection depends on automated assembly equipment compatibility and procurement preferences.

Q: Can V230LS20A be replaced with any of these substitutes in existing designs?

A: Yes. All substitute parts are pin-compatible, mechanically identical (14mm disc through-hole package), and electrically equivalent. Direct substitution is possible without circuit redesign or board layout modification.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 rating, meeting the same environmental and regulatory requirements as the original V230LS20A.

Q: Which substitute offers the best availability?

A: V230LT20APX2855 currently has the highest inventory level at 1082 pieces. However, all substitutes maintain active product status with adequate stock levels for production requirements.
