Substitution of the obsolete SS16HE3/5AT is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 750 mV @ 1 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 200 µA @ 60 V
Package / Case: DO-214AC, SMA

Engineering Selection Recommendations

All identified substitute parts are active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full electrical and mechanical compatibility with the obsolete SS16HE3/5AT. Selection among available substitutes is determined by supply chain requirements and application classification:

For Industrial Applications: Parts B160-E3/5AT, B160-E3/61T, B160-M3/5AT, B160-M3/61T, SS16-E3/5AT, SS16-E3/61T, SS16-M3/5AT, and SS16-M3/61T are suitable. These parts carry ROHS3 compliance and MSL 1 rating. Selection between B160 and SS16 base series depends on supplier availability. Packaging format selection (Cut Tape, Tape & Reel, or Digi-Reel) is determined by assembly process requirements and volume.

For Automotive Applications: Parts SS16HE3_B/H and SS16HE3_B/I are qualified to AEC-Q101 automotive standard and carry automotive grade designation. These parts are required for applications subject to automotive qualification requirements. SS16HE3_B/I offers significantly higher inventory availability (85,400 units) compared to SS16HE3_B/H (18,200 units).

Compliance Status: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity level, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for SS16HE3/5AT?

A: All listed substitute parts are electrically and mechanically equivalent to SS16HE3/5AT. Direct replacement is supported without circuit modification. Differences in packaging format (Cut Tape, Tape & Reel, Digi-Reel) do not affect electrical performance but influence assembly process compatibility and supply logistics.

Q: What is the difference between B160 and SS16 base series parts?

A: Both B160 and SS16 series parts share identical electrical specifications (60 V, 1 A, 750 mV forward voltage, fast recovery ≤ 500ns). The difference is in base product numbering and internal device architecture. Both are fully equivalent for circuit application. Selection is based on supplier availability and procurement preference.

Q: Are automotive-grade parts (SS16HE3_B/H and SS16HE3_B/I) required for all applications?

A: Automotive-grade parts with AEC-Q101 qualification are required only for applications subject to automotive industry standards and qualification requirements. Industrial applications can use standard-grade equivalents. Automotive-grade parts carry higher inventory availability and are suitable for any application, including industrial use.

Q: What packaging formats are available, and how do they differ?

A: Three packaging formats are available: Cut Tape (CT) & Digi-Reel®, Cut Tape (CT), and Tape & Reel (TR). These formats differ in supply method and quantity per reel but contain identical components. Selection depends on assembly equipment compatibility and volume requirements. Cut Tape formats support lower-volume or mixed-component assembly. Tape & Reel format supports high-volume automated assembly.

Q: Which substitute part has the highest inventory availability?

A: SS16HE3_B/I (automotive-grade, Tape & Reel format) offers the highest inventory availability at 85,400 units. SS16-E3/61T (industrial-grade, Cut Tape & Digi-Reel format) offers 153,834 units. Both parts are suitable for immediate procurement.

Q: Do all substitute parts maintain the same operating temperature range?

A: All substitute parts maintain identical operating junction temperature range of -65°C to 150°C, matching the original SS16HE3/5AT specification.

Q: Are there compliance or certification differences between substitute parts?

A: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. The only certification difference is automotive-grade parts (SS16HE3_B/H and SS16HE3_B/I) carry AEC-Q101 qualification, which is not present in standard industrial-grade equivalents. This qualification is required only for automotive applications.
