Substitute Part Grouping Explanation

Substitute parts for the SB260E-G are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 60 V (exact match required)
• Current - Average Rectified (Io): 2 A (exact match required)
• Technology: Schottky (exact match required)
• Mounting Type: Through Hole (exact match required)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (exact match required)

Secondary Compatibility Factors:

• Forward voltage (Vf) within acceptable engineering tolerance
• Reverse leakage current within specified limits
• Operating temperature range compatibility
• Package form factor (axial through-hole variants)
• Regulatory compliance (RoHS3, REACH, ECCN)

Two substitute parts meet these criteria with variations in package designation and reverse leakage specifications.

Parameter Comparison

Engineering Selection Recommendations

SB260-E3/73 (Vishay General Semiconductor - Diodes Division)

This substitute part is electrically equivalent to the SB260E-G with identical voltage and current ratings. The forward voltage is 20 mV lower (680 mV vs 700 mV @ 2A), which represents improved efficiency characteristics. The reverse leakage current matches the original specification at 500 µA @ 60V. The operating temperature range extends to 150°C, providing broader thermal margin compared to the SB260E-G. Package designation is DO-204AC (DO-15), maintaining mechanical compatibility with through-hole PCB layouts. All regulatory certifications (RoHS3, REACH, EAR99) align with the original part. This substitute is suitable for direct replacement in applications where the extended temperature range provides additional design margin.

SR206-TP (Micro Commercial Co)

This substitute part meets the core electrical requirements with 60V reverse voltage and 2A average rectified current. Forward voltage matches the original specification at 700 mV @ 2A. The reverse leakage current is specified at 1 mA @ 60V, which is higher than the original 500 µA specification. The package form factor is DO-41 (DO-204AL), which differs from the DO-15 package of the original part. Both are axial through-hole configurations, but physical dimensions and PCB footprint spacing differ. The operating temperature range is -50°C ~ 125°C, matching the lower bound of the original but not extending to -65°C. All regulatory certifications are compliant. This substitute is applicable when PCB layout accommodates the DO-41 package footprint and the higher reverse leakage current is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can SB260-E3/73 be used as a direct replacement for SB260E-G?

A: Yes. The SB260-E3/73 is electrically equivalent with identical voltage (60V) and current (2A) ratings. Both use DO-15 package configurations suitable for through-hole mounting. The forward voltage is slightly lower (680 mV vs 700 mV), and the operating temperature range is extended to 150°C. All regulatory compliance certifications match.

Q: What is the primary difference between SB260-E3/73 and SR206-TP?

A: The primary differences are package form factor and reverse leakage current. SB260-E3/73 uses DO-15 packaging with 500 µA reverse leakage, while SR206-TP uses DO-41 packaging with 1 mA reverse leakage. Both maintain 60V/2A electrical specifications and fast recovery characteristics.

Q: Can SR206-TP be used in place of SB260E-G without PCB modification?

A: No. SR206-TP uses a DO-41 package, which has different physical dimensions and lead spacing compared to the DO-15 package of SB260E-G. PCB footprint modification is required. Additionally, the reverse leakage current is higher (1 mA vs 500 µA), which must be evaluated for circuit performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. SB260E-G, SB260-E3/73, and SR206-TP are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the temperature operating range difference between the substitutes?

A: SB260E-G and SR206-TP both operate from -65°C to 125°C (or -50°C to 125°C for SR206-TP at the lower bound). SB260-E3/73 extends to 150°C maximum junction temperature, providing additional thermal margin in high-temperature applications.

Q: Does forward voltage difference affect circuit performance?

A: The forward voltage difference between SB260E-G (700 mV) and SB260-E3/73 (680 mV) is 20 mV. In power supply and rectification circuits, this represents improved efficiency. The impact depends on circuit design; low-voltage, high-current applications may benefit from the lower forward voltage of the Vishay part.

Q: Are all parts available in the same packaging format?

A: No. SB260E-G and SB260-E3/73 are both available in DO-15 (DO-204AC) axial through-hole packages. SR206-TP is available in DO-41 (DO-204AL) axial through-hole package. Package selection affects PCB layout and mechanical fit.
