Engineering Selection Recommendations

RSFDL R3G is the preferred parametric equivalent for new designs. This part maintains identical electrical specifications to the RSFDLHM2G, including reverse voltage, rectified current, forward voltage, and reverse recovery time. The RSFDL R3G carries Active product status, ensuring long-term availability and design continuity. Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 and AEC-Q101 automotive standards.

RSFDL is a parametric equivalent available in higher inventory quantities (13,300 pcs) but carries Not For New Designs product status. This part is suitable for legacy system support and replacement applications where design changes are not feasible. The RSFDL maintains identical electrical and mechanical specifications to the RSFDLHM2G.

RS07D-GS08 from Vishay General Semiconductor - Diodes Division is a similar manufacturer alternative that meets core electrical requirements with minor parameter variations. The RS07D-GS08 exhibits lower forward voltage (1.15 V @ 700 mA versus 1.3 V @ 500 mA) and higher reverse leakage current (10 µA versus 5 µA @ 200 V). This part carries Active product status and AEC-Q101 automotive qualification. The RS07D-GS08 is suitable for applications where the parameter variations are within system tolerance margins.

All substitute parts maintain DO-219AB package compatibility and identical operating temperature ranges (-55°C ~ 150°C). Selection between parametric equivalents and similar manufacturer alternatives depends on supply availability, inventory requirements, and application-specific tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can RSFDL R3G be used as a direct replacement for RSFDLHM2G?

A: Yes. The RSFDL R3G is a parametric equivalent with identical electrical specifications including 200V reverse voltage, 500mA rectified current, 1.3V forward voltage @ 500mA, and 150ns reverse recovery time. Both parts use the DO-219AB package and Sub SMA supplier device package. The primary difference is packaging format (Cut Tape for RSFDL R3G versus the main part's standard packaging) and product status (Active for RSFDL R3G).

Q: What is the difference between RSFDL and RSFDL R3G?

A: Both RSFDL and RSFDL R3G are parametric equivalents with identical electrical specifications. The differences are packaging format (RSFDL is supplied in Tape & Reel format, RSFDL R3G in Cut Tape format) and product status (RSFDL is Not For New Designs, RSFDL R3G is Active). For new designs, RSFDL R3G is the appropriate selection.

Q: Can RS07D-GS08 replace RSFDLHM2G in all applications?

A: RS07D-GS08 is a similar manufacturer alternative that meets the core electrical requirements of 200V reverse voltage and 500mA rectified current. However, it exhibits parameter variations: forward voltage of 1.15V @ 700mA (versus 1.3V @ 500mA) and reverse leakage of 10µA @ 200V (versus 5µA @ 200V). Substitution is valid only when these parameter variations are within application tolerance specifications.

Q: Are all substitute parts automotive-qualified?

A: RSFDLHM2G and RS07D-GS08 both carry Automotive grade designation and AEC-Q101 qualification. RSFDL and RSFDL R3G do not specify automotive grade or AEC-Q101 qualification in their documentation. For automotive applications requiring AEC-Q101 compliance, RSFDLHM2G or RS07D-GS08 are the appropriate selections.

Q: What packaging formats are available for these parts?

A: RSFDLHM2G is supplied in standard packaging format. RSFDL is available in Tape & Reel (TR) format with 13,300 pcs inventory. RSFDL R3G is available in Cut Tape (CT) format with 725 pcs inventory. RS07D-GS08 is available in Tape & Reel (TR) format with 20,200 pcs inventory. All parts use the DO-219AB package standard.

Q: Do all substitute parts comply with RoHS and REACH regulations?

A: Yes. All parts listed (RSFDLHM2G, RSFDL, RSFDL R3G, and RS07D-GS08) are ROHS3 Compliant and REACH Unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the operating temperature range for these diodes?

A: All substitute parts maintain an identical operating temperature range of -55°C to 150°C junction temperature, ensuring thermal compatibility across all equivalent and similar manufacturer alternatives.
