Parametric Equivalent: The HS3JB (Tape & Reel packaging variant) is a direct parametric equivalent, differing only in packaging format (Tape & Reel versus Cut Tape).

Similar Parts with Reduced Current Rating: Parts with current ratings below 3 A (CURB205-G at 2 A, MURS160-13-F at 1 A, MURS160-E3/52T at 2 A, MURS160-E3/5BT at 2 A, MURS260-E3/52T at 2 A, MURS260-E3/5BT at 2 A, MURS360S-E3/52T at 1.5 A, MURS360S-E3/5BT at 1.5 A, RS2J-13-F at 1.5 A) maintain the 600 V reverse voltage rating and DO-214AA package but operate at lower current levels. These parts are suitable for applications where the circuit current requirement does not exceed their respective ratings.

Engineering Selection Recommendations

Direct Parametric Equivalent: The HS3JB (Tape & Reel variant) is the recommended replacement for the discontinued HS3JB R5G. This part maintains identical electrical specifications (600 V, 3 A, 75 ns reverse recovery time) and package format while offering active product status and higher inventory availability (6891 Pcs). Both variants are ROHS3 compliant and carry identical compliance certifications.

Alternative Selection Based on Application Requirements: For applications where circuit current demand does not exceed 2 A, the MURS160-E3/5BT, MURS260-E3/5BT, or CURB205-G provide active alternatives with 600 V reverse voltage rating and DO-214AA packaging. These parts maintain fast recovery characteristics and ROHS3 compliance.

For applications where circuit current demand does not exceed 1.5 A, the MURS360S-E3/5BT or RS2J-13-F provide active alternatives with 600 V reverse voltage rating and DO-214AA packaging.

For applications where circuit current demand does not exceed 1 A, the MURS160-13-F provides an active alternative with 600 V reverse voltage rating and DO-214AA packaging.

All substitute parts listed maintain surface mount DO-214AA (SMB) package compatibility, fast recovery speed classification, and ROHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can the HS3JB (Tape & Reel) directly replace the HS3JB R5G (Cut Tape)? A: Yes. The HS3JB in Tape & Reel packaging is a direct parametric equivalent. Both parts share identical electrical specifications: 600 V reverse voltage, 3 A average rectified current, 1.7 V forward voltage at 3 A, and 75 ns reverse recovery time. The only difference is packaging format (Tape & Reel versus Cut Tape). Both are ROHS3 compliant and operate across -55°C to 150°C junction temperature range.

Q: What is the minimum current rating required for a substitute part? A: The substitute part's average rectified current (Io) rating must equal or exceed the circuit's maximum operating current. The HS3JB R5G is rated for 3 A. If your circuit operates at 3 A or higher, only the HS3JB (Tape & Reel) provides a direct equivalent. If your circuit operates below 3 A, lower-rated parts such as MURS260-E3/5BT (2 A), MURS360S-E3/5BT (1.5 A), or MURS160-13-F (1 A) are suitable.

Q: Are all substitute parts in the same DO-214AA package? A: Yes. All parts listed in this reference maintain the DO-214AA (SMB) surface mount package format, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Q: What is the significance of reverse recovery time (trr) in diode selection? A: Reverse recovery time indicates the speed at which the diode transitions from conducting to blocking state. The HS3JB R5G specifies 75 ns. Most substitute parts maintain this specification or lower values (MURS160-13-F at 50 ns, RS2J-13-F at 250 ns). Lower trr values reduce switching losses in high-frequency applications.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All parts listed are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging? A: Cut Tape packaging supplies components on tape that is cut into individual strips, suitable for manual handling and smaller volume applications. Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes and higher volume production. Both formats contain identical components; packaging format selection depends on assembly methodology and volume requirements.

Q: Can I use a lower-rated diode if my circuit current is below the HS3JB R5G rating? A: Yes, provided the substitute part's current rating equals or exceeds your circuit's maximum operating current. For example, if your circuit operates at 1.5 A maximum, the MURS360S-E3/5BT (1.5 A rating) is suitable. However, the part must maintain the 600 V reverse voltage rating and DO-214AA package format.

Q: What forward voltage differences exist among substitute parts? A: Forward voltage varies by manufacturer and design. The HS3JB R5G specifies 1.7 V @ 3 A. Substitute parts range from 1.25 V (MURS160 series) to 1.45 V (MURS260 and MURS360S series). Lower forward voltage reduces power dissipation in the diode. Selection should account for circuit design requirements and thermal management considerations.
