Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

RS1DL (Taiwan Semiconductor Corporation) is a parametric equivalent to RS1DL RTG with identical electrical specifications and DO-219AB packaging. The only distinction is packaging format: RS1DL RTG is supplied in standard packaging while RS1DL is supplied in Tape & Reel format. Both parts maintain ROHS3 compliance and Active product status. This part is suitable for direct substitution in applications requiring the exact 800 mA current rating and 150 ns recovery time.

Higher Current Capacity Substitutes:

SE10FD-M3/H (Vishay) and VS-1EFH02-M3/I (Vishay) both provide 1 A current capacity, exceeding the RS1DL RTG specification. SE10FD-M3/H operates with Standard Recovery characteristics (780 ns trr), while VS-1EFH02-M3/I maintains Fast Recovery performance (16 ns trr). Both are ROHS3 compliant and Active status. VS-1EFH02-M3/I offers superior reverse recovery time and lower forward voltage characteristics.

VS-2EFH02HM3/I (Vishay) provides 2 A current capacity with Fast Recovery characteristics (25 ns trr) and includes AEC-Q101 automotive qualification. This part is suitable for applications requiring higher current margins or automotive-grade reliability.

Lower Current Capacity Substitute:

RS07D-GS08 (Vishay) provides 500 mA current capacity, below the RS1DL RTG specification. This part is suitable only for applications where the circuit design permits reduced current rating. It maintains Fast Recovery performance (150 ns trr) and includes AEC-Q101 automotive qualification. ROHS3 compliance and Active status are maintained.

All substitute parts maintain the 200 V reverse voltage rating, DO-219AB package compatibility, and surface mount mounting type required for mechanical and electrical interchangeability within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can RS1DL be used as a direct replacement for RS1DL RTG?

A: Yes. RS1DL is a parametric equivalent with identical electrical specifications (200 V, 800 mA, 150 ns trr, 1.3 V forward voltage). The parts differ only in packaging format: RS1DL RTG uses standard packaging while RS1DL uses Tape & Reel format. Both are ROHS3 compliant and Active status.

Q: What is the difference between Fast Recovery and Standard Recovery classifications?

A: Fast Recovery diodes have reverse recovery time ≤ 500 ns for currents > 200 mA, while Standard Recovery diodes exceed 500 ns. RS1DL RTG specifies Fast Recovery with 150 ns trr. SE10FD-M3/H uses Standard Recovery (780 ns trr), which may introduce additional switching losses in high-frequency applications. VS-1EFH02-M3/I and VS-2EFH02HM3/I maintain Fast Recovery performance with significantly lower trr values (16 ns and 25 ns respectively).

Q: Can I use a higher current-rated diode as a substitute?

A: Yes, provided all other parameters meet or exceed the RS1DL RTG specification. SE10FD-M3/H (1 A), VS-1EFH02-M3/I (1 A), and VS-2EFH02HM3/I (2 A) all exceed the 800 mA requirement and maintain 200 V reverse voltage rating and DO-219AB packaging. Higher current capacity provides design margin but does not compromise compatibility.

Q: Why would I select RS07D-GS08 if it has lower current capacity?

A: RS07D-GS08 is rated for 500 mA, below the RS1DL RTG specification of 800 mA. This part is suitable only for circuit designs where the actual operating current does not exceed 500 mA. It includes AEC-Q101 automotive qualification, which may be required for automotive applications. Use only when circuit analysis confirms current requirements are within the 500 mA limit.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the DO-219AB package with Surface Mount mounting type, ensuring mechanical compatibility with the RS1DL RTG PCB footprint. No layout modifications are required for physical placement.

Q: What is the significance of the forward voltage (Vf) differences between parts?

A: Forward voltage affects power dissipation and circuit efficiency. RS1DL RTG specifies 1.3 V @ 800 mA. VS-1EFH02-M3/I and VS-2EFH02HM3/I offer lower forward voltages (930 mV and 950 mV respectively), reducing power loss. SE10FD-M3/H provides 1.05 V @ 1 A. Lower forward voltage is advantageous in power-sensitive applications but does not affect functional compatibility.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and maintain Active product status, ensuring regulatory compliance and long-term availability.

Q: What is the operating temperature range consideration for substitution?

A: RS1DL RTG operates from -55°C to 150°C junction temperature. SE10FD-M3/H, VS-1EFH02-M3/I, and VS-2EFH02HM3/I extend the upper limit to 175°C, providing additional thermal margin. RS07D-GS08 maintains the -55°C to 150°C range. Extended temperature range does not affect compatibility but provides design flexibility for high-temperature environments.

Q: Is automotive qualification (AEC-Q101) required for my application?

A: AEC-Q101 qualification is specified for RS07D-GS08 and VS-2EFH02HM3/I. This qualification is required for automotive applications but not necessary for general industrial or consumer applications. Verify application requirements before selecting a qualified part.
