Engineering Selection Recommendations

Vishay SB560-E3/54 and SB560-E3/73 are direct parametric equivalents to the SB560/4, manufactured by the original equipment supplier. Both parts are in active production status with identical electrical specifications. These parts are ROHS3 compliant and REACH unaffected. Selection between these two variants is determined by packaging and supply chain requirements; both are available in Cut Tape format with high inventory levels (18,000 and 9,200 units respectively).

Good-Ark Semiconductor SB560 is a direct manufacturer equivalent with active product status. This part exhibits lower reverse leakage current (150 µA versus 500 µA) and slightly higher forward voltage (670 mV versus 650 mV), both within acceptable operating margins for Schottky rectifier applications. The operating temperature range is -55°C to 150°C, which is narrower at the lower bound than the original part. This part is ROHS3 compliant and available in high volume (31,900 units).

Micro Commercial Co SR506 series (SR506-AP, SR506-BP, SR506-TP) are manufacturer-recommended alternatives with active product status. These parts exhibit forward voltage of 700 mV and reverse leakage of 1 mA, both at the upper acceptable limits. The operating temperature range is -50°C to 150°C. Packaging options include Bulk (SR506-AP, SR506-BP) and Cut Tape (SR506-TP). All three variants are ROHS3 compliant and REACH unaffected.

Selection priority is based on product status (active versus obsolete), compliance certifications (ROHS3, REACH), and application temperature requirements. For applications requiring the full -65°C lower temperature bound, Vishay SB560-E3 variants are required. For applications operating above -55°C, all substitute parts are suitable.

Frequently Asked Questions (FAQ)

Q: Can SB560-E3/54 and SB560-E3/73 be used interchangeably with SB560/4?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (60 V, 5 A, 650 mV forward voltage, 500 µA reverse leakage). The difference between these two Vishay variants is packaging and supplier tape configuration, not electrical performance.

Q: What is the difference between the Vishay SB560-E3 series and the Good-Ark SB560?

A: Both are 60 V, 5 A Schottky rectifiers in DO-201AD packages. The Good-Ark SB560 has lower reverse leakage (150 µA versus 500 µA) and slightly higher forward voltage (670 mV versus 650 mV). The operating temperature range is -55°C to 150°C for Good-Ark versus -65°C to 150°C for Vishay. For applications requiring operation below -55°C, the Vishay part is required.

Q: Are the Micro Commercial Co SR506 series parts suitable replacements?

A: Yes, with parameter awareness. SR506-AP, SR506-BP, and SR506-TP meet the 60 V, 5 A core requirements and fast recovery speed specification. Forward voltage is 700 mV (versus 650 mV for the original) and reverse leakage is 1 mA (versus 500 µA). Operating temperature range is -50°C to 150°C. These parts are suitable for applications not requiring operation below -50°C.

Q: What packaging options are available for substitutes?

A: Vishay SB560-E3/54 and SB560-E3/73 are supplied in Cut Tape (CT) format. Good-Ark SB560 is available in Cut Tape and Digi-Reel format. Micro Commercial Co SR506-AP and SR506-BP are supplied in Bulk packaging; SR506-TP is supplied in Cut Tape. The original SB560/4 was supplied in Bulk format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SB560-E3/54, SB560-E3/73, Good-Ark SB560, and all SR506 variants (SR506-AP, SR506-BP, SR506-TP) are ROHS3 compliant and REACH unaffected.

Q: Which substitute part has the lowest reverse leakage current?

A: Good-Ark SB560 has the lowest reverse leakage at 150 µA @ 60 V, compared to 500 µA for the original SB560/4 and Vishay SB560-E3 variants, and 1 mA for the Micro Commercial Co SR506 series.

Q: What is the inventory status of substitute parts?

A: Vishay SB560-E3/54 has 18,000 units in stock. Vishay SB560-E3/73 has 9,200 units. Good-Ark SB560 has 31,900 units. Micro Commercial Co SR506-TP has 1,862 units; SR506-AP has 870 units; SR506-BP has 812 units.
