Substitute Part Grouping Explanation

Substitute parts for the HS1KL RHG are identified based on the following critical electrical and mechanical parameters:

Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 800 V
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Substitution Basis: The identified substitute parts RS07K-GS08 and RS07K-GS18 share identical reverse voltage ratings (800 V), package type (DO-219AB), and mounting configuration. Both parts operate within the same temperature range and meet the same fast recovery speed classification. Current rating differences (500 mA vs. 1 A) and forward voltage variations are secondary parameters that determine application suitability within the same voltage and package class.

Engineering Selection Recommendations

HS1KL RHG (Main Part): Select this part when the application requires 1 A average rectified current capacity with 800 V reverse voltage rating. This component is Active status with ROHS3 compliance and unlimited moisture sensitivity rating. The Sub SMA package designation indicates specific supplier packaging.

RS07K-GS08 (Cut Tape & Digi-Reel® Packaging): This substitute is suitable for applications requiring 500 mA average rectified current at 800 V reverse voltage. The part is Active status, ROHS3 compliant, and AEC-Q101 qualified for automotive applications. The Cut Tape and Digi-Reel® packaging format supports high-volume automated assembly processes.

RS07K-GS18 (Tape & Reel Packaging): This substitute is suitable for applications requiring 500 mA average rectified current at 800 V reverse voltage. The part is Active status, ROHS3 compliant, and AEC-Q101 qualified for automotive applications. The Tape & Reel packaging format supports continuous automated assembly operations.

Substitution Constraints: The RS07K-GS08 and RS07K-GS18 parts are rated for 500 mA average rectified current, which is 50% of the HS1KL RHG rating. These substitutes are applicable only in circuits where the maximum required current does not exceed 500 mA. Both substitute parts exhibit lower forward voltage (1.3 V vs. 1.7 V) and lower reverse leakage current (2 µA vs. 5 µA), which may provide improved efficiency in specific applications.

Frequently Asked Questions (FAQ)

Q: Can RS07K-GS08 or RS07K-GS18 be used as direct replacements for HS1KL RHG?

A: Direct replacement is possible only if the circuit design does not require current exceeding 500 mA. Both substitute parts share the same 800 V reverse voltage rating, DO-219AB package, and Surface Mount configuration. Current rating is the primary limiting factor for substitution.

Q: What is the difference between RS07K-GS08 and RS07K-GS18?

A: Both parts are electrically identical with 500 mA current rating and 800 V reverse voltage. The primary difference is packaging format: RS07K-GS08 is supplied in Cut Tape and Digi-Reel® format, while RS07K-GS18 is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Are the substitute parts suitable for automotive applications?

A: RS07K-GS08 and RS07K-GS18 are both AEC-Q101 qualified, indicating automotive-grade qualification. The main part HS1KL RHG does not specify automotive qualification in the provided data.

Q: How do the reverse recovery times compare?

A: The HS1KL RHG has a reverse recovery time of 75 ns, while both RS07K-GS08 and RS07K-GS18 have 300 ns. All three parts meet the Fast Recovery classification (≤ 500ns, > 200mA). The faster recovery time of the main part may provide advantages in high-frequency switching applications.

Q: What are the temperature operating ranges?

A: All three parts operate across the same junction temperature range of -55°C to 150°C, ensuring thermal compatibility in equivalent circuit designs.

Q: Do all parts meet RoHS and REACH compliance?

A: Yes. The HS1KL RHG, RS07K-GS08, and RS07K-GS18 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
