SS16HE3-LTP Equivalent & Substitute Parts

Part Overview

The SS16HE3-LTP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 60 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance.

Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives within the same electrical and mechanical specifications. The SS16HE3-LTP has documented parametric equivalents and cross-compatible alternatives from both the original manufacturer and qualified secondary sources.

• Voltage - Forward (Vf) (Max) @ If: 700 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Current - Reverse Leakage @ Vr: Permitted range 100 µA to 500 µA @ 60 V
• Capacitance @ Vr, F: Permitted range 45 pF to 110 pF (measurement conditions may vary)
• Product Status: Active or Obsolete (for existing inventory applications)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats
• Grade and Qualification: Automotive grade with AEC-Q101 qualification preferred but not mandatory for all substitutes

All identified substitute parts maintain electrical equivalence within these defined parameters and are suitable for direct replacement in applications designed for the SS16HE3-LTP.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Automotive Qualified):

SS16-AU_R1_000A1 and SS16_R1_00001 from Panjit International Inc. are direct functional equivalents with Active product status and AEC-Q101 automotive qualification matching the original SS16HE3-LTP. These parts are suitable for applications requiring automotive-grade reliability and long-term availability assurance.

Secondary Substitutes (Active Status, Standard Grade):

SS16-LTP from Micro Commercial Co and SS16W_R1_00001 from Panjit International Inc. maintain full electrical equivalence with Active product status. These parts are suitable for applications where automotive qualification is not a design requirement. SS16-LTP offers the highest current inventory level (55,100 pcs), providing supply security for high-volume production.

Tertiary Substitute (Obsolete Status):

SS16E-TP from Micro Commercial Co is classified as Obsolete product status. This part maintains electrical equivalence but should be selected only when existing inventory must be consumed or when design flexibility permits use of end-of-life components. Continued availability cannot be assured.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compatibility with the original SS16HE3-LTP across all identified applications.

Frequently Asked Questions (FAQ)

Q: Can SS16-LTP be used as a direct replacement for SS16HE3-LTP?

A: Yes. SS16-LTP is a parametric equivalent with identical voltage, current, and thermal ratings. Both parts are manufactured by Micro Commercial Co in the same DO-214AC (SMA) package. The primary difference is reverse leakage current (500 µA vs. 100 µA) and capacitance (110 pF vs. 45 pF), which fall within allowable substitution parameters. SS16-LTP is suitable for direct replacement in all applications designed for SS16HE3-LTP.

Q: What is the difference between Panjit and Micro Commercial Co versions?

A: Both manufacturers produce Schottky diodes with identical electrical specifications for the 60 V, 1 A rating. Panjit parts (SS16-AU_R1_000A1, SS16_R1_00001, SS16W_R1_00001) are qualified to AEC-Q101 automotive standards where specified. Micro Commercial Co parts (SS16HE3-LTP, SS16-LTP) are also automotive qualified. Selection between manufacturers is based on supply availability, inventory levels, and procurement preferences.

Q: Why does SS16E-TP show Obsolete status?

A: SS16E-TP is marked as Obsolete, indicating the manufacturer has discontinued active production. However, inventory remains available (28,950 pcs). This part should be used only when existing stock must be consumed or when design flexibility permits use of end-of-life components. For new designs or long-term production, Active status parts are recommended.

Q: Are there packaging format differences between substitutes?

A: Yes. SS16HE3-LTP, SS16-LTP, SS16-AU_R1_000A1, SS16_R1_00001, and SS16W_R1_00001 are supplied in Tape & Reel (TR) format. SS16E-TP is supplied in Cut Tape (CT) and Digi-Reel® formats. All formats are compatible with standard surface mount assembly equipment. Selection depends on production line requirements and tape reel specifications.

Q: What is the significance of reverse leakage current variation?

A: Reverse leakage current ranges from 100 µA to 500 µA across the substitute parts, all measured at 60 V. This parameter indicates the small current flowing through the diode in reverse bias condition. Both values are within acceptable limits for Schottky rectifier applications. Selection should be based on circuit requirements; lower leakage (100 µA) is preferred for low-power or high-impedance applications.

Q: Can I use SS16W_R1_00001 if capacitance is not specified?

A: Yes. SS16W_R1_00001 is electrically equivalent to SS16HE3-LTP across all critical parameters. The unspecified capacitance does not affect substitution eligibility. Capacitance values (45 pF to 110 pF) across all parts are typical for Schottky diodes in this class and do not impact circuit performance in standard rectification applications.

Q: Which substitute offers the best supply availability?

A: SS16-LTP from Micro Commercial Co has the highest inventory level at 55,100 pcs, followed by SS16E-TP at 28,950 pcs and SS16W_R1_00001 at 20,400 pcs. For applications requiring immediate availability and high-volume procurement, SS16-LTP is the optimal choice.

Q: Are all substitutes suitable for automotive applications?

A: SS16HE3-LTP, SS16-AU_R1_000A1, and SS16_R1_00001 carry explicit AEC-Q101 automotive qualification. SS16-LTP, SS16E-TP, and SS16W_R1_00001 do not list automotive qualification in their specifications. For automotive applications requiring AEC-Q101 compliance, use only SS16HE3-LTP, SS16-AU_R1_000A1, or SS16_R1_00001.
