Engineering Selection Recommendations

SF58G-TP (Micro Commercial Co)

The SF58G-TP is the direct manufacturer equivalent from Micro Commercial Co, offering active product status with identical electrical specifications to the SF58-TP. This part is preferred for designs requiring continuity within the same manufacturer ecosystem. The SF58G-TP features an extended operating temperature range (-65°C to 150°C) compared to the main part and is available in Tape & Reel packaging for automated assembly processes. Forward voltage is 1.75 V at 5 A, representing a 0.05 V increase within acceptable tolerance. ROHS3 compliance and MSL 1 rating are maintained.

ER506_R2_00001 (Panjit International Inc.)

The ER506_R2_00001 is a parametric equivalent from Panjit International Inc., providing active product status with identical core electrical specifications. This part offers improved reverse leakage characteristics (1 µA versus 5 µA at 600 V), reducing standby current consumption. Available in Cut Tape packaging, this part is suitable for semi-automated or manual assembly workflows. ROHS3 compliance and REACH unaffected status are confirmed. Capacitance is 65 pF at 4 V, 1 MHz.

ER506_T0_00001 (Panjit International Inc.)

The ER506_T0_00001 is a parametric equivalent from Panjit International Inc., providing active product status with identical core electrical specifications to the main part. This part offers the same improved reverse leakage characteristics as the ER506_R2_00001 (1 µA at 600 V). Available in Tube packaging, this part is suitable for manual assembly and component handling workflows. ROHS3 compliance and REACH unaffected status are confirmed.

All three substitute parts maintain the critical electrical parameters: 600 V reverse voltage, 5 A average rectified current, 35 ns reverse recovery time, and DO-201AD axial through-hole package configuration. Selection among substitutes depends on packaging requirements, assembly process compatibility, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can SF58G-TP replace SF58-TP in existing designs?

A: Yes. The SF58G-TP maintains identical electrical specifications (600 V, 5 A, 35 ns reverse recovery time) and the same DO-201AD axial through-hole package. The SF58G-TP offers active product status, extended temperature range (-65°C to 150°C), and ROHS3 compliance. Forward voltage increases by 0.05 V (1.75 V versus 1.7 V at 5 A), which is within acceptable tolerance for general-purpose rectifier applications.

Q: What is the difference between the Panjit ER506 variants?

A: The ER506_R2_00001 and ER506_T0_00001 are electrically identical, differing only in packaging format. The ER506_R2_00001 is supplied in Cut Tape (CT) packaging, while the ER506_T0_00001 is supplied in Tube packaging. Both maintain 600 V, 5 A, 35 ns specifications and offer improved reverse leakage (1 µA at 600 V). Selection depends on assembly process requirements and handling preferences.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (SF58G-TP, ER506_R2_00001, ER506_T0_00001) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The Panjit parts additionally carry REACH unaffected status.

Q: What packaging options are available for substitutes?

A: SF58G-TP is available in Tape & Reel (TR) for automated assembly. ER506_R2_00001 is available in Cut Tape (CT) for semi-automated assembly. ER506_T0_00001 is available in Tube packaging for manual assembly. All maintain the DO-201AD axial through-hole form factor.

Q: Do substitute parts have different reverse leakage characteristics?

A: Yes. The SF58-TP and SF58G-TP specify 5 µA reverse leakage at 600 V. The Panjit ER506 variants (ER506_R2_00001 and ER506_T0_00001) specify 1 µA reverse leakage at 600 V, representing improved leakage performance. Lower reverse leakage reduces standby current consumption in applications with sustained reverse bias conditions.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All substitute parts use the DO-201AD axial through-hole package with identical pin spacing and mechanical dimensions. PCB footprints and through-hole mounting requirements are identical across all parts. No PCB redesign is required for substitution.

Q: What is the operating temperature range for each part?

A: SF58-TP and Panjit ER506 variants operate from -55°C to 150°C junction temperature. SF58G-TP offers an extended range from -65°C to 150°C, providing additional low-temperature margin for applications requiring operation below -55°C.
