Substitute Part Grouping Explanation

Substitute parts for the S2J R5G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: 600 V reverse voltage, 2 A average rectified current, 1.15 V forward voltage at 2 A, standard recovery speed, DO-214AA package, and operating temperature range. These parts are direct functional replacements.

Similar Parts share the same 600 V reverse voltage rating and DO-214AA package but differ in one or more of the following parameters: average rectified current (1 A or 1.5 A instead of 2 A), forward voltage characteristics, reverse recovery time (fast recovery ≤500 ns instead of standard >500 ns), reverse leakage current (5 µA instead of 1 µA), or operating temperature range. These parts are suitable for applications where the specified differences do not compromise circuit performance.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 600 V
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Current - Average Rectified (Io): 2 A (for parametric equivalents) or ≥ required circuit current (for similar parts)
Voltage - Forward (Vf) (Max): ≤ 1.15 V @ 2 A (for parametric equivalents)
Operating Temperature - Junction: -55°C minimum (for parametric equivalents)

Engineering Selection Recommendations

Parametric Equivalent - Recommended Primary Replacement:

The S2J from Nexperia USA Inc. is the recommended primary replacement for the discontinued S2J R5G. This part maintains identical electrical specifications including 600 V reverse voltage, 2 A average rectified current, 1.15 V forward voltage at 2 A, and standard recovery characteristics. The Nexperia S2J offers an extended minimum operating temperature of -65°C compared to the original -55°C, providing improved low-temperature performance. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The Nexperia part is currently in active production with substantial inventory availability.

Parametric Equivalent - Alternative Replacement:

The S2JH from Taiwan Semiconductor Corporation (original manufacturer) is an active alternative that maintains identical electrical and thermal specifications to the S2J R5G. This part is packaged in Tape & Reel format and carries AEC-Q101 automotive qualification. The S2JH is suitable for applications requiring automotive-grade components or when maintaining the original manufacturer source is preferred.

These parts feature fast recovery characteristics (≤500 ns, 75 ns trr) compared to the standard recovery of the S2J R5G. The forward voltage is 1.25 V at 1 A, and reverse leakage is 5 µA at 600 V. Operating temperature range extends to -65°C to 175°C. These parts are suitable for applications where faster switching performance is beneficial.

Similar Parts - Reduced Current Alternatives:

The MURS160-13-F from Diodes Incorporated is rated for 1 A average rectified current with 600 V reverse voltage. This part features fast recovery (50 ns trr) and extended operating temperature to 175°C. This part is suitable only for applications where the circuit current requirement does not exceed 1 A.

The MURS360S series (E3/52T, E3/5BT, M3/5BT variants) from Vishay General Semiconductor are rated for 1.5 A average rectified current with 600 V reverse voltage.

Frequently Asked Questions (FAQ)

Q: Can the S2J from Nexperia be used as a direct replacement for the S2J R5G?

A: Yes. The Nexperia S2J is a parametric equivalent with identical voltage, current, and forward voltage specifications. The primary difference is an extended minimum operating temperature (-65°C versus -55°C), which provides improved performance in low-temperature environments. Both parts use the DO-214AA package and are ROHS3 compliant.

Q: What is the difference between the S2JH and the S2J R5G?

A: The S2JH maintains identical electrical specifications to the S2J R5G, including 600 V reverse voltage, 2 A current rating, 1.15 V forward voltage, and 1.5 µs reverse recovery time. The S2JH is supplied in Tape & Reel packaging and carries AEC-Q101 automotive qualification. The S2JH is currently in active production.

Q: Can MURS160 series parts replace the S2J R5G?

A: MURS160 series parts maintain the 600 V reverse voltage and 2 A current rating but differ in recovery characteristics (fast recovery ≤500 ns versus standard recovery >500 ns) and forward voltage (1.25 V at 1 A versus 1.15 V at 2 A). These parts are suitable for applications where faster switching performance is acceptable or required. The extended operating temperature range (-65°C to 175°C) provides additional thermal margin.

Q: What is the significance of the 1.5 A rating on MURS360S parts?

A: MURS360S parts are rated for 1.5 A average rectified current, which is lower than the 2 A rating of the S2J R5G. These parts are suitable only for applications where the circuit current requirement does not exceed 1.5 A. Using a lower-rated part in a circuit requiring 2 A would result in thermal stress and potential device failure.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts listed use the DO-214AA (SMB) surface mount package. However, packaging formats (Cut Tape, Tape & Reel, or bulk) vary by part number and manufacturer. Verify the specific packaging format required for your procurement and assembly process before finalizing part selection.

Q: What does "fast recovery" mean compared to "standard recovery"?

A: Recovery speed refers to the reverse recovery time (trr), which is the time required for the diode to transition from forward conduction to reverse blocking. Standard recovery diodes (S2J R5G: 1.5 µs) are suitable for general-purpose rectification. Fast recovery diodes (MURS160 series: 75 ns) switch more quickly and generate less switching noise, making them preferable in high-frequency applications or where electromagnetic interference must be minimized.

Q: Can I use a MURS160-13-F (1 A rated) in place of the S2J R5G (2 A rated)?

A: No. The MURS160-13-F is rated for only 1 A average rectified current. Using this part in a circuit requiring 2 A operation would exceed the device rating and result in excessive junction temperature, reduced reliability, and potential failure. Current rating must equal or exceed the circuit requirement.

Q: What is the importance of the operating temperature range?

A: The operating temperature range specifies the junction temperature limits within which the diode maintains specified electrical characteristics. The S2J R5G operates from -55°C to 150°C. Substitute parts with extended ranges (such as -65°C to 175°C) provide additional margin for applications with extreme thermal environments. However, the circuit design must ensure the actual junction temperature remains within the specified range.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the S2J R5G.
