Substitute Part Grouping Explanation

Substitute parts RS07K-GS08 and RS07K-GS18 are qualified as electrical and mechanical equivalents based on the following criteria:

Matching Parameters:

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

Substitution Basis: Both RS07K-GS08 and RS07K-GS18 maintain identical reverse voltage rating and package form factor, enabling direct mechanical and electrical substitution in DO-219AB footprints. The primary difference between these substitute parts and the main part HS1KL RQG is the average rectified current rating (500 mA versus 1 A) and reverse recovery time specification. RS07K-GS08 and RS07K-GS18 differ only in packaging format: RS07K-GS08 is supplied in Cut Tape (CT) & Digi-Reel format, while RS07K-GS18 is supplied in Tape & Reel (TR) format.

Engineering Selection Recommendations

HS1KL RQG Selection Criteria: The HS1KL RQG is appropriate for applications requiring 1 A average rectified current at 800 V reverse voltage with standard-grade specifications. This part is Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

RS07K-GS08 Selection Criteria: RS07K-GS08 is suitable for applications with maximum 500 mA average rectified current requirements at 800 V reverse voltage. This part carries Automotive grade classification with AEC-Q101 qualification, ROHS3 compliance, and is supplied in Cut Tape & Digi-Reel packaging format. Selection of this part is appropriate where automotive-grade reliability and lower current ratings satisfy application requirements.

RS07K-GS18 Selection Criteria: RS07K-GS18 is functionally identical to RS07K-GS08 with identical electrical specifications and Automotive grade with AEC-Q101 qualification. The primary distinction is packaging format: RS07K-GS18 is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. Selection of this part is appropriate where Tape & Reel packaging and automotive-grade specifications are required.

Substitution Limitations: Substitution of HS1KL RQG with RS07K-GS08 or RS07K-GS18 is limited to applications where the 500 mA average rectified current rating is sufficient. Applications requiring the full 1 A rating of the HS1KL RQG cannot use these substitute parts. The longer reverse recovery time (300 ns versus 75 ns) of the substitute parts must be evaluated for switching frequency and EMI performance in the target application.

Frequently Asked Questions (FAQ)

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

A: RS07K-GS08 and RS07K-GS18 are mechanically compatible in DO-219AB footprints and share the 800 V reverse voltage rating. However, these parts are rated for 500 mA average rectified current compared to the HS1KL RQG's 1 A rating. Substitution is valid only for applications where 500 mA current capacity is sufficient. The reverse recovery time difference (300 ns versus 75 ns) must be evaluated for the specific application's switching characteristics.

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

A: RS07K-GS08 and RS07K-GS18 have identical electrical specifications and both carry Automotive grade with AEC-Q101 qualification. The only 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. Selection between these parts depends on assembly process requirements and volume considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The HS1KL RQG, RS07K-GS08, and RS07K-GS18 are all ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the Automotive grade and AEC-Q101 qualification on the substitute parts?

A: Automotive grade classification and AEC-Q101 qualification indicate that RS07K-GS08 and RS07K-GS18 meet automotive industry reliability and quality standards. The HS1KL RQG carries Standard grade classification without automotive qualification. Selection of automotive-qualified parts is appropriate for automotive applications; however, this does not affect electrical compatibility in non-automotive applications.

Q: Can the HS1KL RQG be substituted with RS07K-GS08 or RS07K-GS18 in high-current applications?

A: No. Applications requiring the full 1 A average rectified current rating of the HS1KL RQG cannot use RS07K-GS08 or RS07K-GS18, which are rated for 500 mA maximum. Exceeding the rated current of a component results in thermal stress and reduced component reliability.

Q: How do the reverse recovery time specifications affect substitution?

A: The HS1KL RQG has a reverse recovery time of 75 ns, while RS07K-GS08 and RS07K-GS18 have 300 ns. In high-frequency switching applications, the longer recovery time of the substitute parts may result in increased switching losses and EMI. Applications with switching frequencies below approximately 100 kHz typically tolerate this difference without performance degradation.

Q: Are there inventory considerations for selecting substitute parts?

A: Yes. The HS1KL RQG has 1,157 pieces in stock, while RS07K-GS08 has 50,300 pieces and RS07K-GS18 has 50,802 pieces in stock. Substitute parts offer significantly higher inventory availability, which may be relevant for supply chain planning and lead time considerations.
