Substitute Part Grouping Explanation

Substitution of the S2K-TP is determined by the following critical parameters:

Mandatory Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 800 V minimum
Current - Average Rectified (Io): 2 A minimum
Package / Case: DO-214AA (SMB) surface mount
Mounting Type: Surface Mount
Technology: Standard rectifier diode

Acceptable Variation Criteria:

Voltage - Forward (Vf) (Max) @ If: Equal or lower forward voltage drop
Reverse Recovery Time (trr): Equal or faster recovery
Current - Reverse Leakage @ Vr: Equal or lower leakage current
Operating Temperature - Junction: Equal or wider temperature range

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents: Parts from the same manufacturer (Micro Commercial Co) with identical electrical specifications and packaging, differing only in product status or packaging configuration.

Parametric Equivalents: Parts from alternative manufacturers (Diotec Semiconductor, Diodes Incorporated, Taiwan Semiconductor Corporation, Vishay General Semiconductor) that meet or exceed all mandatory and acceptable variation criteria within the same package form factor.

Engineering Selection Recommendations

Primary Recommendation: S2K-LTP (Micro Commercial Co)

The S2K-LTP is the direct manufacturer equivalent of the S2K-TP, supplied by Micro Commercial Co with active product status. This part maintains identical electrical specifications (800 V, 2 A, 1.15 V forward voltage) and packaging (DO-214AA SMB). The S2K-LTP exhibits lower reverse leakage current (5 µA versus 10 µA) and is available in Tape & Reel packaging. RoHS3 compliance and MSL 1 rating are maintained. This part provides the most direct replacement path with no design modifications required.

Secondary Recommendations: S2K (Diotec Semiconductor) and S2KH (Taiwan Semiconductor Corporation)

Both parts meet all mandatory electrical criteria with 800 V reverse voltage and 2 A current rating. The S2K from Diotec Semiconductor offers faster reverse recovery time (1.5 µs versus 2 µs) and lower reverse leakage (5 µA). The S2KH from Taiwan Semiconductor Corporation provides the lowest reverse leakage current (1 µA) and includes AEC-Q101 automotive qualification with active product status. Both are available in Tape & Reel packaging and maintain RoHS3 compliance.

Alternative Recommendation: SB2K-M3/52T and SB2K-M3/5BT (Vishay General Semiconductor - Diodes Division)

These Vishay parts meet all mandatory specifications with 800 V reverse voltage and 2 A current rating. Both exhibit low reverse leakage current (1 µA) and maintain the 2 µs reverse recovery time of the original part. Both are available in Tape & Reel packaging with RoHS3 compliance and active product status. These parts provide robust alternatives from an established semiconductor manufacturer.

Not Recommended: S2K-13-F (Diodes Incorporated)

While this part shares the same 800 V reverse voltage rating and DO-214AA package, the current rating is reduced to 1.5 A, below the 2 A requirement of the S2K-TP. This part is suitable only for applications with reduced current requirements and does not provide full electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can S2K-13-F be used as a direct replacement for S2K-TP?

A: No. The S2K-13-F is rated for 1.5 A average rectified current, while the S2K-TP is rated for 2 A. Use of the S2K-13-F in a 2 A application would exceed the component's current rating and create reliability risk. The S2K-13-F is suitable only for applications with maximum current requirements of 1.5 A or less.

Q: What is the difference between S2K-LTP and S2K-TP?

A: The S2K-LTP and S2K-TP are electrically equivalent, both rated for 800 V and 2 A with identical forward voltage characteristics. The primary differences are product status (S2K-LTP is active; S2K-TP is discontinued) and packaging configuration (S2K-LTP is supplied in Tape & Reel; S2K-TP packaging is not specified). The S2K-LTP exhibits lower reverse leakage current (5 µA versus 10 µA).

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts listed are supplied in DO-214AA (SMB) surface mount package, enabling direct PCB footprint compatibility with the S2K-TP. Packaging configurations vary between bulk and Tape & Reel formats, but the physical package dimensions and pin configuration remain identical.

Q: Does the S2KH automotive qualification affect its use in non-automotive applications?

A: No. The S2KH includes AEC-Q101 automotive qualification, which indicates compliance with automotive reliability and testing standards. This qualification does not restrict use in non-automotive applications. The S2KH meets all electrical specifications of the S2K-TP and is suitable for any application within its rated parameters.

Q: What is the significance of reverse leakage current differences among substitute parts?

A: Reverse leakage current represents the small current flowing through the diode in reverse bias condition. Lower reverse leakage current (1 µA in S2KH, SB2K-M3/52T, and SB2K-M3/5BT versus 10 µA in S2K-TP) indicates superior reverse blocking characteristics and lower power dissipation in reverse bias. For most applications, this difference is negligible; however, in high-impedance circuits or low-power applications, lower leakage current may provide performance benefits.

Q: Can reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and switching losses in rectifier applications. The S2K-TP specifies 2 µs recovery time. Substitute parts with faster recovery (1.5 µs in S2K and S2KH) will exhibit lower switching losses and faster switching transitions. Parts with identical 2 µs recovery time (SB2K-M3/52T and SB2K-M3/5BT) provide equivalent switching performance. For standard rectification applications at line frequency, recovery time differences have minimal impact; for higher-frequency switching applications, faster recovery may provide efficiency improvements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance, consistent with the S2K-TP. REACH status is either "REACH Unaffected" or "REACH info available upon request" across all parts, indicating compliance with environmental and chemical restriction regulations.

Q: What is MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This is the least restrictive moisture sensitivity classification and simplifies inventory management and procurement logistics compared to higher MSL ratings.
