RS1KLSHRVG Equivalent & Substitute Parts

Part Overview

The RS1KLSHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 1.2 A average rectified current in a surface-mount SOD-123HE package. This component is classified as Active and compliant with RoHS3 and REACH regulations. Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternative sources that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the RS1KLSHRVG is permissible when the replacement part meets all of the following criteria:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 800 V
Current - Average Rectified (Io): 1.2 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.2 A
Reverse Recovery Time (trr): 300 ns
Current - Reverse Leakage @ Vr: 5 µA @ 800 V
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Package / Case: SOD-123H
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C

Compliance Requirements:

RoHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)
REACH Unaffected status

Parts meeting these specifications are electrically and mechanically interchangeable. Differences in manufacturer, product status, or additional certifications do not affect functional equivalence when all electrical parameters and package specifications are identical.

Engineering Selection Recommendations

RS1KLS (Taiwan Semiconductor Corporation)

The RS1KLS is a parametric equivalent to the RS1KLSHRVG with identical electrical specifications and Active product status. Both parts are manufactured by Taiwan Semiconductor Corporation and share the same base product number (RS1K). This substitute is suitable for new designs and ongoing production applications. The RS1KLS maintains full compliance with RoHS3 and REACH requirements.

RS1KFP (onsemi)

The RS1KFP is a parametric equivalent with identical electrical specifications and package configuration. However, this part carries a "Not For New Designs" product status designation. The RS1KFP is qualified to AEC-Q101 automotive standards and includes automotive-grade classification. This substitute is appropriate for legacy system maintenance, field replacements, or applications where automotive qualification is required. The RS1KFP is not recommended for new design implementations due to its product status classification.

Frequently Asked Questions (FAQ)

Q: Can RS1KLS be used as a direct replacement for RS1KLSHRVG?

A: Yes. The RS1KLS meets all electrical and mechanical specifications of the RS1KLSHRVG, including voltage rating, current rating, forward voltage, reverse recovery time, reverse leakage current, package type, and operating temperature range. Both parts are Active and RoHS3 compliant.

Q: What is the difference between RS1KLSHRVG and RS1KFP?

A: The electrical specifications are identical. The primary differences are manufacturer (Taiwan Semiconductor Corporation versus onsemi) and product status (Active versus Not For New Designs). The RS1KFP includes automotive-grade qualification (AEC-Q101), which may be relevant for specific applications.

Q: Why is RS1KFP marked "Not For New Designs"?

A: This designation indicates that the manufacturer recommends against using this part number in new product designs. However, the part remains functionally equivalent and may be used for legacy system support or replacement applications where the electrical specifications are required.

Q: Are all three parts interchangeable in the same PCB footprint?

A: Yes. All three parts use the SOD-123H package with surface-mount configuration. They are mechanically and electrically interchangeable at the board level.

Q: Do these substitute parts require any design modifications?

A: No. All substitute parts maintain identical electrical parameters, package specifications, and operating temperature ranges. No circuit modifications or board redesign is necessary.

Q: Which substitute should be selected for new product development?

A: The RS1KLS is the recommended choice for new designs, as it carries Active product status and is manufactured by the same supplier as the primary part number.

Q: Are there any compliance differences between these parts?

A: All three parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. The RS1KFP includes additional AEC-Q101 automotive qualification, which is not present in the other variants.
