Engineering Selection Recommendations

Primary Equivalent (Direct Replacement):

RS1D-13-F is the direct parametric equivalent to RS1D-13, manufactured by Diodes Incorporated. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. Selection of RS1D-13-F eliminates the need for circuit re-qualification and provides the most straightforward transition from the discontinued RS1D-13.

Active Substitutes for New Designs:

For applications requiring RoHS3 compliance and active product status, the following parts are suitable substitutes:

ES1D-E3/61T (Vishay General Semiconductor) offers the lowest reverse recovery time (25 ns) and reduced forward voltage (920 mV @ 1 A), with the highest inventory availability (2,328,659 pcs). This part is recommended for high-volume production requiring superior switching performance.

ES1D-LTP (Micro Commercial Co) provides extended operating temperature range (-65°C ~ 175°C) with active status and substantial inventory (335,300 pcs), suitable for applications requiring wider thermal operating margins.

CURA103-G (Comchip Technology) delivers ultrafast recovery characteristics (50 ns) with reduced forward voltage (1 V @ 1 A) and active product status, appropriate for switching applications requiring faster transient response.

Legacy Substitutes (Not For New Designs):

RGF1D (onsemi) and EGF1D (onsemi) are classified as "Not For New Designs" and should be used only for maintenance of existing equipment or legacy system support. Both parts maintain electrical compatibility with RS1D-13 while offering extended temperature ranges and RoHS3 compliance.

Package Compatibility Note:

RGF1D-E3/67A uses DO-214BA package instead of DO-214AC (SMA). While electrically equivalent, this package variant requires PCB layout modification and is not a direct mechanical substitute.

Frequently Asked Questions (FAQ)

Q: Can RS1D-13-F be used as a direct replacement for RS1D-13 without circuit modification?

A: Yes. RS1D-13-F is a parametric equivalent with identical electrical specifications (200 V, 1 A, 1.3 V forward voltage, 150 ns recovery time) and the same DO-214AC SMA package. No circuit modification is required.

Q: What is the difference between ES1D-E3/61T and ES1D-E3/5AT?

A: Both parts are manufactured by Vishay and share identical electrical ratings (200 V, 1 A, 920 mV forward voltage, 25 ns recovery time). The primary difference is packaging format: ES1D-E3/61T is supplied in Cut Tape format, while ES1D-E3/5AT is also available in Tape & Reel. Electrical performance is equivalent.

Q: Why do some substitutes have lower forward voltage than RS1D-13?

A: Forward voltage variation within the specified range (920 mV to 1.3 V @ 1 A) is normal across different manufacturers and process technologies. Lower forward voltage reduces power dissipation and heat generation, which is beneficial in most applications. Verify that the application circuit can tolerate the specified forward voltage range.

Q: Is RGF1D-E3/67A compatible with RS1D-13 PCB layouts?

A: RGF1D-E3/67A uses DO-214BA package instead of DO-214AC (SMA). While electrically equivalent, the physical package dimensions differ, requiring PCB layout modification. Direct mechanical substitution is not possible without redesign.

Q: Which substitute offers the best availability?

A: ES1D-E3/61T (Vishay General Semiconductor) has the highest inventory at 2,328,659 pcs. This part is recommended for high-volume applications requiring immediate availability and active product status.

Q: Can legacy parts like RGF1D or EGF1D be used in new designs?

A: Both RGF1D and EGF1D are classified as "Not For New Designs." These parts are suitable only for maintenance and repair of existing equipment. For new designs, select from active status parts: RS1D-13-F, ES1D-E3/61T, ES1D-LTP, CURA103-G, CSFA103-G, or ES1D.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and electromagnetic interference characteristics. RS1D-13 specifies 150 ns. Substitutes with faster recovery times (25 ns to 50 ns) provide improved switching performance and reduced noise, beneficial in high-frequency applications. Slower recovery times do not preclude substitution if the application does not require enhanced switching performance.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All active and recommended substitute parts listed are ROHS3 compliant. RS1D-13 is RoHS non-compliant. Selection of any substitute provides compliance upgrade for new designs.

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

A: RS1D-13 operates from -65°C to 150°C. Most substitutes maintain this range or extend it to 175°C. CSFA103-G and CURA103-G operate from -55°C to 150°C, reducing the lower temperature limit by 10°C. Verify application requirements before selecting these parts.

Q: Can CURA103-G be used in place of RS1D-13 for general-purpose rectification?

A: Yes. CURA103-G meets all electrical requirements (200 V, 1 A, fast recovery) and is rated for general-purpose rectification. The ultrafast recovery characteristic (50 ns) provides performance enhancement over RS1D-13 (150 ns) without introducing compatibility issues in standard rectifier applications.
