Engineering Selection Recommendations

For New Designs: RS1KLS is the primary substitute for the S1KLS RVG. Both components are manufactured by Taiwan Semiconductor Corporation with Active product status, ensuring long-term availability and support. Electrical parameters are identical, and both comply with ROHS3 and REACH requirements.

For Existing Designs or Automotive Applications: RS1KFP is a parametric equivalent with identical electrical ratings and package compatibility. However, RS1KFP carries a "Not For New Designs" product status and is qualified to AEC-Q101 automotive standards. Selection of RS1KFP is appropriate only when automotive-grade qualification is a design requirement or when existing inventory constraints necessitate its use.

Compliance Considerations: All three parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Moisture Sensitivity Level is 1 (Unlimited) for all variants, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can RS1KLS be used as a direct replacement for S1KLS RVG? A: Yes. RS1KLS is a parametric equivalent with identical voltage rating (800 V), current rating (1.2 A), forward voltage drop (1.3 V @ 1.2 A), and package configuration (SOD-123H surface mount). Both are Active products from Taiwan Semiconductor Corporation.

Q: What is the difference between RS1KLS and RS1KFP? A: Both parts have identical electrical specifications and package compatibility. The primary differences are: RS1KLS is manufactured by Taiwan Semiconductor Corporation with Active status; RS1KFP is manufactured by onsemi with "Not For New Designs" status and includes AEC-Q101 automotive qualification. RS1KFP specifies reverse recovery time (trr) at 300 ns.

Q: Is RS1KFP suitable for new product designs? A: RS1KFP carries a "Not For New Designs" product status. It is suitable for replacement in existing designs or applications requiring automotive-grade qualification (AEC-Q101). For new designs, RS1KLS or S1KLS RVG are the recommended selections.

Q: Are there package or mounting differences between these parts? A: No. All three parts use the SOD-123H package with surface-mount configuration. PCB layout and assembly processes are identical across all variants.

Q: Do these parts require special handling during storage or assembly? A: No. All three parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage and handling procedures apply.

Q: Are all three parts RoHS compliant? A: Yes. S1KLS RVG, RS1KLS, and RS1KFP are all ROHS3 Compliant and REACH Unaffected, meeting environmental regulatory requirements for commercial and industrial applications.
