Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

SS16L R3G is the parametric equivalent from Taiwan Semiconductor Corporation, maintaining identical electrical specifications and automotive-grade qualification. However, this part is discontinued at DiGi Electronics, limiting long-term availability for production and field service applications.

Recommended Substitutes (Active Product Status):

SS1FH6HM3/H is the preferred substitute for automotive applications requiring AEC-Q101 qualification. This Vishay part maintains the 60 V / 1 A electrical specification with improved reverse leakage performance (3 µA vs. 400 µA) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 150°C). Automotive grade designation and AEC-Q101 qualification ensure compliance with automotive reliability standards.

SS1FH6-M3/H provides equivalent electrical performance with identical reverse leakage and temperature characteristics but lacks automotive grade designation. This part is suitable for non-automotive applications or where automotive qualification is not required.

Higher Current Alternative:

SS2FH6HM3/H operates at 60 V / 2 A with automotive qualification and AEC-Q101 certification. This part is applicable when circuit design permits increased current capacity within the same voltage class and package footprint, providing design margin for thermal and reliability considerations.

Frequently Asked Questions (FAQ)

Q: Can SS16L R3G be used as a direct replacement for SS16LHRUG?

A: SS16L R3G is a parametric equivalent with identical electrical specifications (60 V, 1 A, 700 mV forward voltage, fast recovery). However, this part is discontinued at DiGi Electronics, making it unsuitable for new production designs or long-term field service support.

Q: What is the primary difference between SS16LHRUG and the Vishay SS1FH6HM3/H substitute?

A: Both parts meet the 60 V / 1 A specification and DO-219AB package requirement. The SS1FH6HM3/H provides superior reverse leakage performance (3 µA vs. 400 µA @ 60 V) and extended junction temperature range (-55°C ~ 175°C vs. -55°C ~ 150°C). Both maintain automotive grade and AEC-Q101 qualification.

Q: Is SS1FH6-M3/H suitable for automotive applications?

A: SS1FH6-M3/H meets the electrical specifications for 60 V / 1 A operation with improved reverse leakage (3 µA) and extended temperature range. However, this part lacks automotive grade designation and AEC-Q101 qualification. Use is restricted to non-automotive applications or where automotive certification is not required.

Q: When should SS2FH6HM3/H be selected instead of 1 A alternatives?

A: SS2FH6HM3/H is selected when circuit design permits 2 A average rectified current operation. This higher current rating provides design margin for thermal management and reliability in applications where the 1 A specification is marginal. The 60 V voltage rating and DO-219AB package remain compatible with SS16LHRUG footprints.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts (SS16L R3G, SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the SS16LHRUG.

Q: What is the impact of reverse leakage differences between SS16LHRUG and Vishay substitutes?

A: SS16LHRUG specifies 400 µA reverse leakage at 60 V, while Vishay parts (SS1FH6-M3/H, SS1FH6HM3/H, SS2FH6HM3/H) specify 3 µA. Lower reverse leakage reduces standby power dissipation and improves circuit efficiency. This difference is significant in low-power or battery-operated applications but may be negligible in high-current rectification circuits.

Q: Can these parts be used interchangeably in existing PCB designs?

A: All substitute parts use the DO-219AB package (Sub SMA), ensuring mechanical and electrical compatibility with existing PCB footprints designed for SS16LHRUG. No PCB redesign is required for package compatibility.
