Engineering Selection Recommendations
Direct Parametric Equivalents (Recommended for Direct Replacement):
The SS16H manufactured by Taiwan Semiconductor Corporation is the primary direct equivalent. It maintains identical electrical specifications (60 V, 1 A, 750 mV forward voltage, 200 µA reverse leakage) and operating temperature range (-55°C to 150°C) as the SS16 R3G. The SS16H is active in production and carries AEC-Q101 automotive qualification, providing enhanced reliability documentation. The primary difference is packaging format: SS16H is supplied in Tape & Reel (TR) format versus the original Cut Tape (CT) format.
The SS16 manufactured by EVVO Semi provides an alternative parametric equivalent with active product status and high inventory availability (105,200 pcs). This part maintains the 60 V, 1 A electrical ratings and DO-214AC (SMA) package. Forward voltage is reduced to 700 mV @ 1 A, and reverse leakage is increased to 300 µA @ 60 V. Operating temperature range is -55°C to 125°C, which is narrower than the original part. This part is suitable for applications not requiring the full 150°C upper temperature limit.
Compatible Substitutes (Same Voltage and Current Rating):
The B160-E3/5AT and B160-E3/61T manufactured by Vishay General Semiconductor - Diodes Division are fully compatible substitutes. Both maintain 60 V, 1 A ratings with 750 mV forward voltage and 200 µA reverse leakage. Operating temperature extends to -65°C lower bound, providing enhanced cold-temperature performance. These parts are active in production with established supply chains.
The B160-13-F manufactured by Diodes Incorporated is an active substitute with 60 V, 1 A ratings in DO-214AC (SMA) package. Forward voltage is 700 mV @ 1 A, and reverse leakage is 500 µA @ 60 V. Operating temperature range is -65°C to 150°C. This part has high inventory availability (245,300 pcs).
The B160Q-13-F manufactured by Diodes Incorporated is an automotive-qualified substitute (AEC-Q101) with identical voltage and current ratings. This part is suitable for applications requiring automotive-grade components and carries active product status with substantial inventory (55,300 pcs).
Higher Current Capacity Alternatives (For Applications Permitting Increased Current Rating):
The B260AQ-13-F manufactured by Diodes Incorporated provides 60 V, 2 A capability in the same DO-214AC (SMA) package. This part carries AEC-Q101 automotive qualification and is suitable for applications where increased current capacity does not create thermal or design conflicts.
The B360A-E3/5AT and B360A-E3/61T manufactured by Vishay General Semiconductor - Diodes Division provide 60 V, 3 A capability. These parts maintain the DO-214AC (SMA) package and operating temperature range of -55°C to 150°C, matching the original part's thermal specifications.
Product Status Consideration:
All recommended substitutes maintain active product status, ensuring ongoing availability and supply chain stability. The original SS16 R3G is discontinued at DiGi Electronics, making transition to an active equivalent necessary for new production and long-term support.
Frequently Asked Questions (FAQ)
Q: Can the SS16 R3G be directly replaced with the SS16H?
A: Yes. The SS16H is a direct parametric equivalent with identical electrical specifications (60 V, 1 A, 750 mV forward voltage, 200 µA reverse leakage) and operating temperature range (-55°C to 150°C). The primary difference is packaging format: SS16H is supplied in Tape & Reel (TR) versus the original Cut Tape (CT). Both use the DO-214AC (SMA) package and are RoHS3 compliant. The SS16H is active in production and carries AEC-Q101 automotive qualification.
Q: What is the difference between the SS16 (EVVO Semi) and SS16 R3G?
A: Both parts maintain 60 V, 1 A electrical ratings and DO-214AC (SMA) packaging. The EVVO Semi SS16 has a lower forward voltage (700 mV vs. 750 mV) and higher reverse leakage (300 µA vs. 200 µA). The operating temperature range is narrower: -55°C to 125°C versus -55°C to 150°C. The EVVO Semi part is suitable for applications not requiring operation above 125°C and offers high inventory availability.
Q: Are the B160 series parts (Diodes Incorporated and Vishay) compatible with the SS16 R3G?
A: Yes. The B160-13-F, B160-E3/5AT, and B160-E3/61T all maintain 60 V, 1 A electrical ratings in DO-214AC (SMA) packages. All are active in production. The Vishay parts (B160-E3/5AT and B160-E3/61T) match the original forward voltage (750 mV) and reverse leakage (200 µA). The Diodes Incorporated B160-13-F has slightly lower forward voltage (700 mV) and higher reverse leakage (500 µA). Operating temperature ranges extend to -65°C, providing enhanced cold-temperature performance.
Q: What is the difference between B160-13-F and B160Q-13-F?
A: Both parts are manufactured by Diodes Incorporated and maintain 60 V, 1 A ratings in DO-214AC (SMA) packages. The B160Q-13-F carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring documented quality and reliability standards. Electrical specifications are identical: 700 mV forward voltage and 500 µA reverse leakage. Both are active in production.
Q: Can I use the B260AQ-13-F (2 A) or B360A series (3 A) as substitutes?
A: Yes, these higher current-rated parts are electrically compatible substitutes. The B260AQ-13-F provides 2 A capability, and the B360A series provides 3 A capability, all at 60 V in DO-214AC (SMA) packages. These parts are suitable for applications where increased current capacity does not create thermal or design conflicts. The B260AQ-13-F carries AEC-Q101 automotive qualification. Use of higher-rated parts in lower-current applications does not create functional issues but may result in unnecessary cost or board space considerations.
Q: What is the significance of the packaging format difference (Cut Tape vs. Tape & Reel)?
A: Cut Tape (CT) and Tape & Reel (TR) are supply formats affecting handling and assembly processes. Cut Tape is supplied in smaller quantities on cut strips, suitable for manual assembly or small production runs. Tape & Reel is supplied on continuous reels, optimized for automated pick-and-place assembly in high-volume production. Electrically and mechanically, parts in the same package (DO-214AC/SMA) are identical. Selection depends on production volume and assembly equipment capabilities.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed maintain RoHS3 compliance and Moisture Sensitivity Level (MSL) 1 (Unlimited), matching the original SS16 R3G specifications. This ensures compatibility with environmental and regulatory requirements.
Q: What is the operating temperature range difference between the original part and substitutes?
A: The original SS16 R3G operates from -55°C to 150°C. The EVVO Semi SS16 operates from -55°C to 125°C, which is narrower at the upper limit. The Diodes Incorporated and Vishay parts extend the lower limit to -65°C, providing enhanced cold-temperature performance while maintaining the 150°C upper limit. Selection depends on application-specific temperature requirements.
Q: Why do some parts have higher reverse leakage specifications?
A: Reverse leakage current varies by manufacturer and process technology. The original SS16 R3G and equivalent parts (SS16H, B160-E3/5AT, B160-E3/61T, B360A series) specify 200 µA @ 60 V. The Diodes Incorporated B160 series and B260AQ-13-F specify 500 µA @ 60 V. The EVVO Semi SS16 specifies 300 µA @ 60 V. Higher reverse leakage does not affect functionality in most applications but may be a consideration in high-impedance circuits or low-power applications. Verify application requirements before selection.
