Substitute Part Grouping Explanation
Substitution of the S2JHR5G is determined by the following critical parameters: DC reverse voltage rating (600V), average rectified current capacity (2A), forward voltage drop characteristics, package type (DO-214AA SMB), and automotive qualification status (AEC-Q101).
Substitute parts are grouped into two categories:
Parametric Equivalents maintain identical electrical specifications across all critical parameters, including voltage rating, current rating, forward voltage, and recovery characteristics. These parts are direct replacements with no circuit redesign required.
Similar Parts share the same voltage rating (600V) and package type (DO-214AA SMB) but differ in one or more electrical characteristics such as current rating, forward voltage, reverse recovery time, or reverse leakage current. Selection of similar parts requires verification that the application tolerates the parameter differences.

Engineering Selection Recommendations
Parametric Equivalents (Direct Replacements)
The S2J (Nexperia USA Inc.) and S2JH (Taiwan Semiconductor Corporation) are parametric equivalents to the S2JHR5G. Both parts maintain the 600V voltage rating, 2A current rating, and 1.15V forward voltage specification. The S2JH is manufactured by the same supplier as the original part and carries identical automotive qualification (AEC-Q101). The S2J is produced by Nexperia and is currently in active production with substantial inventory availability. Both parts are ROHS3 compliant and suitable for direct substitution without circuit modification.
Similar Parts with Current Rating Below 2A
The MURS160-13-F (1A), RS2J-13-F (1.5A), and S2J-13-F (1.5A) are suitable only for applications where the circuit current demand does not exceed their respective ratings. These parts maintain the 600V voltage rating and DO-214AA package compatibility. The MURS160-13-F exhibits fast recovery characteristics (50 ns) compared to the standard recovery of the original part. The RS2J-13-F and S2J-13-F provide intermediate current ratings with fast and standard recovery options respectively.
Similar Parts with Current Rating Above 2A
The S3JB (3A) and S3JB-TP (3A) provide higher current capacity than the original S2JHR5G. These parts maintain the 600V voltage rating and DO-214AA package compatibility. The S3JB carries automotive qualification (AEC-Q101) matching the original part's grade. These parts are suitable for applications requiring current capacity exceeding 2A.
Package Variant Considerations
The RS2JA-13-F and S2JA-13-F are available in DO-214AC (SMA) package format rather than DO-214AA (SMB). These parts are suitable only for designs that accommodate the SMA package footprint. Both maintain the 600V voltage rating with 1.5A current capacity.
Alternative with Enhanced Recovery Characteristics
The S2J-LTP (Micro Commercial Co) maintains the 2A current rating and 600V voltage specification of the original part while providing fast recovery characteristics (≤ 0.5 µs). This part is suitable for applications sensitive to switching speed performance.
Frequently Asked Questions (FAQ)
Q: Can the S2J (Nexperia) be used as a direct replacement for the S2JHR5G?
A: Yes. The S2J maintains identical voltage rating (600V), current rating (2A), forward voltage (1.15V @ 2A), and package type (DO-214AA SMB). The reverse recovery time differs slightly (2 µs versus 1.5 µs), which is within standard rectifier diode tolerance for most applications. The part is currently in active production with high inventory availability.
Q: What is the difference between the S2JH and S2J substitutes?
A: The S2JH is manufactured by Taiwan Semiconductor Corporation (same as the original S2JHR5G) and carries identical automotive qualification (AEC-Q101). The S2J is manufactured by Nexperia USA Inc. Both parts are parametric equivalents with identical electrical specifications. The S2JH may be preferred for applications requiring supplier continuity or automotive certification from the original manufacturer.
Q: Can I use the MURS160-13-F (1A) in place of the S2JHR5G (2A)?
A: The MURS160-13-F is suitable only if the application circuit current does not exceed 1A. Using a 1A-rated diode in a 2A circuit will result in excessive forward voltage drop and potential thermal failure. The MURS160-13-F does provide fast recovery characteristics (50 ns) if switching speed is a design requirement.
Q: Are the SMA package variants (RS2JA-13-F, S2JA-13-F) compatible with the original SMB footprint?
A: No. The SMA package (DO-214AC) has a different physical footprint than the SMB package (DO-214AA). These parts require PCB layout modification and are suitable only for new designs or boards that accommodate the SMA package format.
Q: What is the advantage of the S3JB or S3JB-TP (3A) over the original S2JHR5G (2A)?
A: The 3A-rated parts provide higher current capacity for applications requiring current levels between 2A and 3A. Both parts maintain the 600V voltage rating and DO-214AA package compatibility. The S3JB carries automotive qualification (AEC-Q101) matching the original part's grade. These parts are suitable for designs with increased current requirements.
Q: Does the S2J-LTP offer any performance advantage over the S2J?
A: The S2J-LTP provides fast recovery characteristics (≤ 0.5 µs) compared to the standard recovery of the S2J (2 µs). This faster switching speed reduces reverse recovery losses and may improve efficiency in high-frequency switching applications. Both parts maintain identical voltage and current ratings.
Q: Are all substitute parts ROHS3 compliant?
A: All listed substitute parts are ROHS3 compliant. The original S2JHR5G is also ROHS3 compliant. Compliance status is consistent across all parametric equivalents and similar parts.
Q: Which substitute part has the lowest reverse leakage current?
A: The S2JHR5G and S2J both specify 1 µA reverse leakage current at 600V. All other substitute parts specify 5 µA or higher reverse leakage current at 600V. Lower reverse leakage current may be beneficial in high-impedance or precision analog circuits.
