SS16HE3_A/I Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS16HE3_A/I is a 60V, 1A Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division in the DO-214AC (SMA) surface mount package. This component is classified as discontinued at DiGi Electronics, though 7900 pieces remain in stock as new original inventory. The part carries automotive-grade qualification (AEC-Q101) and is ROHS3 compliant.

Due to the discontinued status of the SS16HE3_A/I, equivalent substitute parts are necessary for ongoing production requirements, design revisions, and long-term supply chain continuity. Substitute parts must maintain identical electrical performance and mechanical compatibility within the DO-214AC package footprint.

Engineering Selection Recommendations

For Automotive Applications:

The SS16HE3_B/H and SS16HE3_B/I are direct functional replacements for the SS16HE3_A/I. Both parts carry automotive-grade qualification (AEC-Q101) and are currently in active production status. The SS16HE3_B/I offers the highest inventory availability at 85,400 pieces and is the preferred selection for new automotive designs and production continuity.

For Non-Automotive Applications:

The B160 and SS16 series parts (B160-E3/5AT, B160-E3/61T, B160-M3/5AT, B160-M3/61T, SS16-E3/5AT, SS16-E3/61T, SS16-M3/5AT, SS16-M3/61T) provide electrical and mechanical equivalence without automotive qualification. These parts are suitable for industrial and consumer applications where AEC-Q101 certification is not required. All are in active production status.

Packaging Considerations:

Substitute parts are available in three packaging configurations:

Cut Tape (CT) & Digi-Reel®: B160-E3/5AT, SS16-E3/61T
Tape & Reel (TR): B160-M3/5AT, B160-M3/61T, SS16-E3/5AT, SS16-M3/5AT, SS16-M3/61T, SS16HE3_B/H, SS16HE3_B/I

Selection between packaging types depends on assembly process requirements and order quantities. All packaging configurations maintain identical electrical performance and mechanical compatibility.

Compliance Status:

All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part specification. No additional compliance verification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute SS16HE3_A/I with any of the listed B160 series parts?

A: Yes. The B160-E3/5AT, B160-E3/61T, B160-M3/5AT, and B160-M3/61T are electrically and mechanically equivalent to the SS16HE3_A/I. All share identical voltage ratings (60V), current ratings (1A), forward voltage characteristics (750 mV @ 1A), and package specifications (DO-214AC, SMA). The primary difference is the absence of automotive-grade qualification on B160 parts.

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

A: Both series are manufactured by Vishay and meet identical electrical specifications for the 60V, 1A Schottky diode application. The SS16 series includes automotive-qualified variants (SS16HE3_B/H, SS16HE3_B/I), while the B160 series does not carry AEC-Q101 certification. For applications requiring automotive qualification, use SS16HE3_B/H or SS16HE3_B/I.

Q: Does packaging type affect electrical performance?

A: No. Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® packaging configurations contain identical die and lead frame specifications. Packaging type affects only handling, storage, and assembly process compatibility. Electrical performance remains constant across all packaging variants.

Q: Is the SS16HE3_B/I a direct pin-for-pin replacement for SS16HE3_A/I?

A: Yes. Both parts use the DO-214AC (SMA) package with identical pin configuration and footprint. The SS16HE3_B/I is a direct mechanical and electrical replacement suitable for PCB assembly without design modification.

Q: What is the inventory status of substitute parts?

A: SS16HE3_B/I has the highest availability at 85,400 pieces. SS16-E3/61T has 153,834 pieces in stock. Other substitutes range from 816 to 19,200 pieces. Inventory levels should be verified with the supplier for current availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status and MSL rating of 1 (Unlimited), matching the original SS16HE3_A/I specification.

Q: Can I use non-automotive-qualified parts in automotive applications?

A: This determination depends on your specific application requirements and design standards. The B160 series parts lack AEC-Q101 automotive qualification. For applications requiring automotive-grade components, use SS16HE3_B/H or SS16HE3_B/I exclusively.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across the junction temperature range of -65°C to 150°C, identical to the original SS16HE3_A/I specification.
