HS1KL RFG Equivalent & Substitute Parts

Part Overview

The HS1KL RFG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 1 A average rectified current in a Surface Mount Sub SMA package. This component is classified as Active product status and complies with RoHS3 and REACH regulations. Substitute parts are identified to provide alternative sourcing options where inventory availability, packaging formats, or specific application requirements necessitate component alternatives while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Matching Parameters (Required for Substitution):

• Voltage - DC Reverse (Vr) (Max): 800 V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Current - Average Rectified (Io): Substitute parts rated at 500 mA are acceptable for applications requiring ≤ 500 mA
• Reverse Recovery Time (trr): Substitute parts with extended recovery time (300 ns) are acceptable for non-critical switching applications
• Current - Reverse Leakage @ Vr: Lower leakage specifications in substitutes represent improved performance
• Capacitance @ Vr, F: Lower capacitance in substitutes represents improved performance

The identified substitute parts (RS07K-GS08 and RS07K-GS18) share identical voltage ratings, package specifications, and thermal operating ranges. Both substitute parts are manufactured by Vishay General Semiconductor - Diodes Division and carry AEC-Q101 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

HS1KL RFG (Main Part): Use the HS1KL RFG for applications requiring 1 A average rectified current capacity with fast recovery characteristics (75 ns). This part is suitable for general-purpose rectification in 800 V circuits and is compliant with RoHS3 and REACH regulations.

RS07K-GS08 (Cut Tape & Digi-Reel® Packaging): Select RS07K-GS08 as a substitute when applications require ≤ 500 mA average rectified current and Cut Tape or Digi-Reel® packaging formats are preferred. This part carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. Inventory availability is 50,300 pieces.

RS07K-GS18 (Tape & Reel Packaging): Select RS07K-GS18 as a substitute when applications require ≤ 500 mA average rectified current and Tape & Reel packaging format is required for high-volume production. This part carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. Inventory availability is 50,802 pieces.

Both substitute parts demonstrate improved reverse leakage characteristics (2 µA versus 5 µA) and lower junction capacitance (4 pF versus 15 pF), representing enhanced performance in these parameters. The primary trade-off is reduced current capacity (500 mA versus 1 A) and extended reverse recovery time (300 ns versus 75 ns).

Frequently Asked Questions (FAQ)

Q: Can RS07K-GS08 or RS07K-GS18 be used as direct replacements for HS1KL RFG in all applications?

A: RS07K-GS08 and RS07K-GS18 are suitable substitutes only for applications where the average rectified current requirement does not exceed 500 mA. If your circuit requires the full 1 A capacity of the HS1KL RFG, these substitutes are not appropriate. Both substitute parts share identical voltage ratings (800 V), package specifications (DO-219AB), and thermal operating ranges (-55°C ~ 150°C), ensuring mechanical and thermal compatibility.

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

A: RS07K-GS08 and RS07K-GS18 are electrically identical parts with the same specifications. The primary difference is packaging format: RS07K-GS08 is supplied in Cut Tape (CT) & Digi-Reel® format, while RS07K-GS18 is supplied in Tape & Reel (TR) format. Select based on your production assembly requirements and inventory management preferences.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both RS07K-GS08 and RS07K-GS18 carry AEC-Q101 automotive qualification and are classified as Automotive grade. The HS1KL RFG is classified as Standard grade without specified automotive qualification. If automotive-grade qualification is required, the substitute parts provide this certification.

Q: What are the key electrical differences between the main part and substitutes?

A: The main differences are: (1) Current capacity: HS1KL RFG is rated for 1 A while substitutes are rated for 500 mA; (2) Reverse recovery time: HS1KL RFG has 75 ns while substitutes have 300 ns; (3) Reverse leakage: HS1KL RFG has 5 µA while substitutes have 2 µA; (4) Junction capacitance: HS1KL RFG has 15 pF while substitutes have 4 pF. All parts share the same 800 V reverse voltage rating and fast recovery speed classification.

Q: Do all parts comply with environmental regulations?

A: Yes. The HS1KL RFG, RS07K-GS08, and RS07K-GS18 are all ROHS3 compliant and REACH unaffected. All parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: What packaging considerations should I evaluate when selecting a substitute?

A: The HS1KL RFG is supplied in Sub SMA packaging format. RS07K-GS08 is supplied in Cut Tape (CT) & Digi-Reel® format, and RS07K-GS18 is supplied in Tape & Reel (TR) format. All three parts use the DO-219AB package case and Surface Mount mounting type, ensuring PCB footprint compatibility. Packaging format selection depends on your assembly process and volume requirements.
