Engineering Selection Recommendations

RS1KLS is the primary parametric equivalent substitute for the S1KLSHRVG. Both components are manufactured by Taiwan Semiconductor Corporation, maintain Active product status, and are identical in all critical electrical and mechanical specifications. RS1KLS provides equivalent performance with higher inventory availability (31,943 units in stock versus 721 units for the main part).

RS1KFP is a parametric equivalent manufactured by onsemi with identical electrical ratings and package specifications. However, RS1KFP carries a Product Status designation of "Not For New Designs." This part is qualified to AEC-Q101 automotive standards and includes specified capacitance (18 pF @ 0V, 1MHz), indicating automotive-grade qualification. RS1KFP is suitable for replacement or maintenance applications in existing designs but is not recommended for new design implementations.

Selection between RS1KLS and S1KLSHRVG should prioritize RS1KLS for new designs due to Active status and equivalent specifications. RS1KFP is applicable only when automotive qualification or existing design continuity is a specific requirement.

Frequently Asked Questions (FAQ)

Q: Can RS1KLS be used as a direct replacement for S1KLSHRVG?

A: Yes. RS1KLS is a parametric equivalent with identical voltage rating (800 V), current rating (1.2 A), forward voltage (1.3 V @ 1.2 A), speed classification (Fast Recovery ≤ 500ns), reverse leakage (5 µA @ 800 V), package (SOD-123H), and operating temperature range (-55°C to 150°C). Both components are RoHS3 compliant and MSL 1. Direct substitution is supported without circuit modification.

Q: What is the difference between S1KLSHRVG and RS1KFP?

A: S1KLSHRVG and RS1KFP are electrically equivalent in all critical parameters: voltage, current, forward voltage, speed, reverse leakage, package, and temperature range. The primary differences are manufacturer (Taiwan Semiconductor Corporation versus onsemi) and product status (Active versus Not For New Designs). RS1KFP includes automotive qualification (AEC-Q101) and specified capacitance (18 pF @ 0V, 1MHz), which S1KLSHRVG does not specify.

Q: Is the SOD-123HE package compatible with SOD-123H?

A: SOD-123HE is the supplier device package designation for all three parts listed. SOD-123H is the standard package classification. These designations refer to the same physical package form factor and are mechanically and electrically compatible for surface-mount assembly.

Q: Can RS1KFP be used in new product designs?

A: RS1KFP carries a Product Status designation of "Not For New Designs." This part is suitable for replacement, maintenance, or repair of existing designs but is not recommended for new design implementations. For new designs, use S1KLSHRVG or RS1KLS, both of which maintain Active product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. S1KLSHRVG, RS1KLS, and RS1KFP are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the reverse recovery time specification?

A: S1KLSHRVG does not specify reverse recovery time (trr) in its datasheet parameters. RS1KLS and RS1KFP both specify 300 ns reverse recovery time. All three parts meet the Fast Recovery speed classification of ≤ 500ns for currents > 200mA.
