Engineering Selection Recommendations

All substitute parts listed are manufactured by Littelfuse Inc. and maintain full ROHS3 compliance and MSL 1 rating. The primary distinction between substitutes is product status and packaging format.

For new designs and production applications, V230LS4P, V230LT4P, or V230LU4P are recommended as they carry active product status, ensuring long-term supply availability and manufacturer support. The tape & reel packaging format (indicated by the "P" suffix) is optimized for automated assembly processes.

For applications requiring specific reel configurations, parts designated with the X2855 suffix (V230LS4PX2855, V230LT4PX2855, V230LU4PX2855) provide identical electrical performance with alternative packaging specifications.

The series designation (LS, LT, LU) reflects internal Littelfuse product line categorization and does not affect electrical or mechanical compatibility. All series variants are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can V230LS4 be directly replaced with V230LS4P?

A: Yes. V230LS4P is a direct substitute with identical electrical specifications. The primary difference is packaging format: V230LS4 is supplied in bulk, while V230LS4P is supplied in tape & reel format suitable for automated assembly.

Q: Are the different series designations (LS, LT, LU) electrically equivalent?

A: Yes. All series variants (LS, LT, LU) maintain identical electrical and mechanical parameters. Series designation reflects internal product line organization and does not affect performance or compatibility.

Q: What does the X2855 suffix indicate?

A: The X2855 suffix denotes a specific reel configuration or packaging variant. Electrical and mechanical specifications remain identical to parts without this suffix.

Q: Is the V230LS4 still available for purchase?

A: The V230LS4 is classified as obsolete. Active substitute parts (V230LS4P, V230LT4P, V230LU4P, and their X2855 variants) are recommended for new orders and ongoing production requirements.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 rating, matching the compliance profile of the original V230LS4.

Q: Can these parts be used in high-temperature applications?

A: The operating temperature range for all parts is -55°C to 85°C. Applications requiring operation outside this range require alternative component selection.
