Substitute Part Grouping Explanation

Substitution of the SS16LHRTG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 1 A
Technology: Schottky
Package / Case: DO-219AB
Mounting Type: Surface Mount
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: Within 700 mV @ 1 A specification
Current - Reverse Leakage @ Vr: May vary; lower values indicate improved performance
Operating Temperature - Junction: May exceed minimum range; higher maximum ratings are acceptable
Capacitance @ Vr, F: Not specified for main part; not a limiting factor

Compliance Considerations:

RoHS3 Compliance required
AEC-Q101 qualification preferred for automotive applications

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical and mechanical specifications) and Similar Manufacturers (equivalent performance from alternative manufacturers with potential minor parameter variations).

Engineering Selection Recommendations

SS16L R3G (Taiwan Semiconductor Corporation)

This part is a parametric equivalent to the SS16LHRTG with identical electrical specifications and package configuration. However, this part is listed as Discontinued at DiGi Electronics, which may limit long-term availability. Selection of this substitute should be evaluated against supply chain continuity requirements.

SS1FH6-M3/H (Vishay General Semiconductor - Diodes Division)

This part meets all mandatory equivalence criteria for voltage, current, and package specifications. It is manufactured by Vishay and carries Active product status. The reverse leakage current is significantly lower (3 µA versus 400 µA), indicating superior performance characteristics. Operating temperature range extends to 175°C, providing additional thermal margin. This part does not carry explicit automotive grade or AEC-Q101 qualification in the provided data. Selection is appropriate for non-automotive applications or where enhanced performance is beneficial.

SS1FH6HM3/H (Vishay General Semiconductor - Diodes Division)

This part is a direct functional equivalent with identical 1 A current rating and 60 V voltage specification. It carries both Automotive grade and AEC-Q101 qualification, matching the compliance profile of the SS16LHRTG. Reverse leakage current is 3 µA, superior to the main part. Operating temperature extends to 175°C. This part is recommended as the primary substitute for automotive applications requiring AEC-Q101 compliance.

SS2FH6HM3/H (Vishay General Semiconductor - Diodes Division)

This part operates at 2 A average rectified current, exceeding the 1 A specification of the SS16LHRTG. While it maintains 60 V voltage rating and DO-219AB package compatibility, the higher current rating makes it suitable only for applications where increased current capacity is required or acceptable. Forward voltage at 2 A is 780 mV. This part carries Automotive grade and AEC-Q101 qualification. Selection should be limited to designs where the 2 A rating provides functional benefit.

Frequently Asked Questions (FAQ)

Q: Can SS1FH6-M3/H be used as a direct replacement for SS16LHRTG in automotive applications?

A: SS1FH6-M3/H meets all electrical and mechanical specifications for the SS16LHRTG. However, it does not carry explicit AEC-Q101 qualification in the provided data. For automotive applications requiring AEC-Q101 compliance, SS1FH6HM3/H is the appropriate selection.

Q: What is the difference between SS1FH6HM3/H and SS2FH6HM3/H?

A: The primary difference is current rating. SS1FH6HM3/H is rated for 1 A average rectified current, matching the SS16LHRTG specification. SS2FH6HM3/H is rated for 2 A. Both maintain 60 V voltage rating and DO-219AB package. Forward voltage increases to 780 mV at 2 A for the SS2FH6HM3/H. Selection depends on circuit current requirements.

Q: Why is the reverse leakage current lower in Vishay parts compared to the SS16LHRTG?

A: Reverse leakage current values (3 µA for Vishay parts versus 400 µA for SS16LHRTG) reflect manufacturing process differences between manufacturers. Lower leakage indicates improved performance and is acceptable for substitution purposes.

Q: Is SS16L R3G a suitable substitute?

A: SS16L R3G is a parametric equivalent with identical specifications. However, it is listed as Discontinued at DiGi Electronics. This status may impact future availability and supply chain reliability. Active product alternatives are preferred for new designs.

Q: Can these parts be used interchangeably in PCB layouts?

A: All substitute parts use the DO-219AB package with Sub SMA supplier designation and surface mount configuration. PCB footprints are compatible. No layout modifications are required for mechanical substitution.

Q: What compliance certifications are critical for my application?

A: RoHS3 compliance is maintained across all listed parts. For automotive applications, AEC-Q101 qualification is specified. SS1FH6HM3/H and SS2FH6HM3/H carry explicit AEC-Q101 qualification. Verify application requirements before final part selection.

Q: Does operating temperature range affect substitution suitability?

A: The SS16LHRTG operates from -55°C to 150°C. Vishay alternatives extend to 175°C maximum junction temperature. Higher temperature ratings provide additional thermal margin and are acceptable for substitution. Applications operating near 150°C should consider the extended range as a benefit.
