Substitute Part Grouping Explanation

Substitute parts are organized into two functional categories based on mounting type and current rating:

Category 1: Through-Hole Axial Packages (DO-204AL / DO-41) These parts maintain the same physical form factor as the SR010 and are suitable for direct replacement in through-hole PCB applications. Substitutes in this category include MBR1100G, MBR1100RLG, SB1100-T, SB1100E-G, SB1H100-E3/54, SB1H100-E3/73, and SR2010-TP. All maintain 100V reverse voltage rating and fast recovery Schottky technology. Current ratings range from 1A to 2A, exceeding the SR010's 500mA specification.

Category 2: Surface Mount SMA Packages (DO-214AC) These parts provide higher current ratings (2A to 4A) in surface mount configuration. Substitutes include MBRA2H100T3G, NRVTSA4100ET3G, and NRVTSA4100T3G. These require different PCB layout and assembly processes but offer improved thermal performance and higher current capacity.

Key Substitution Parameters:

• Voltage - DC Reverse (Vr) Max: 100V (all substitutes)
• Technology: Schottky (all substitutes)
• Speed: Fast Recovery ≤ 500ns, > 200mA (all substitutes)
• RoHS3 Compliance: All substitutes compliant

Engineering Selection Recommendations

For Direct Through-Hole Replacement (Same Package, Same Mounting):

MBR1100G, MBR1100RLG, SB1100-T, SB1100E-G, SB1H100-E3/54, and SB1H100-E3/73 are suitable direct substitutes for the SR010 in through-hole applications. All maintain 100V reverse voltage rating, Schottky technology, and fast recovery characteristics. These parts are rated for 1A average rectified current, exceeding the SR010's 500mA specification. All are RoHS3 compliant and carry Active product status except where noted. MBR1100RLG offers the highest inventory availability (57,700 pcs) among through-hole alternatives.

For Higher Current Through-Hole Applications:

SR2010-TP provides 2A current rating in the same DO-204AL (DO-41) package, suitable for applications requiring increased current capacity while maintaining the same physical form factor.

For Surface Mount Applications:

MBRA2H100T3G (2A) and NRVTSA4100ET3G or NRVTSA4100T3G (4A) provide surface mount alternatives in DO-214AC (SMA) package. NRVTSA4100ET3G and NRVTSA4100T3G carry AEC-Q101 automotive qualification. Note that NRVTSA4100ET3G and NRVTSA4100T3G are designated Last Time Buy status; MBRA2H100T3G maintains Active status.

Compliance Considerations:

All listed substitutes are RoHS3 compliant and REACH unaffected. NRVTSA4100ET3G and NRVTSA4100T3G include automotive-grade qualification (AEC-Q101), suitable for automotive and high-reliability applications.

Temperature Range Considerations:

The SR010 operates from -55°C to 150°C. Substitutes with extended temperature ranges (-65°C to 175°C) include MBR1100G, MBR1100RLG, MBRA2H100T3G, and SB1H100-E3/54 and SB1H100-E3/73. Applications requiring the full SR010 temperature range are supported by all listed substitutes.

Frequently Asked Questions (FAQ)

Q: Can MBR1100G or MBR1100RLG be used as a direct replacement for SR010 in existing through-hole PCB designs?

A: Yes. Both parts maintain identical 100V reverse voltage rating, Schottky technology, fast recovery characteristics, and DO-204AL (DO-41) axial package. The 1A current rating exceeds SR010's 500mA specification. Physical dimensions and pin configuration are compatible with existing through-hole layouts.

Q: What is the difference between MBR1100G and MBR1100RLG?

A: Both parts are electrically identical with 100V rating and 1A current capacity. The primary difference is packaging: MBR1100G is supplied in Bulk packaging, while MBR1100RLG is supplied in Cut Tape (CT) format. MBR1100RLG offers significantly higher inventory availability (57,700 pcs vs. 1,290 pcs).

Q: Are the Vishay SB1H100-E3/54 and SB1H100-E3/73 parts interchangeable?

A: Yes. Both parts are electrically identical with 100V rating, 1A current capacity, 770mV forward voltage at 1A, and DO-204AL (DO-41) package. The designation difference (E3/54 vs. E3/73) reflects packaging tape configuration only and does not affect electrical performance or compatibility.

Q: Can surface mount alternatives like MBRA2H100T3G replace through-hole SR010 parts?

A: Surface mount parts require different PCB layout, assembly processes, and soldering techniques compared to through-hole components. MBRA2H100T3G is electrically compatible (100V, 2A, Schottky, fast recovery) but is not a direct physical replacement. Use surface mount alternatives only in new designs or PCB revisions that support SMA package mounting.

Q: Why are NRVTSA4100ET3G and NRVTSA4100T3G marked as Last Time Buy?

A: Last Time Buy status indicates these parts are being discontinued. While currently available in high quantities (1,000,400 and 1,000,100 pcs respectively), they should not be selected for new long-term production designs. Use Active status alternatives such as MBRA2H100T3G for new designs requiring surface mount 100V Schottky diodes.

Q: What is the significance of AEC-Q101 qualification on NRVTSA4100ET3G and NRVTSA4100T3G?

A: AEC-Q101 is an automotive industry qualification standard. Parts carrying this qualification meet automotive reliability and quality requirements. These parts are suitable for automotive applications and high-reliability environments where component qualification is mandated.

Q: How does forward voltage (Vf) variation among substitutes affect circuit design?

A: Forward voltage ranges from 660mV to 850mV across the substitute list at their respective rated currents. Lower forward voltage (NRVTSA4100T3G at 660mV @ 4A) results in reduced power dissipation and heat generation. Higher forward voltage (SR010, SB1100E-G, SR2010-TP at 850mV) may require thermal management consideration in high-current applications. Select based on specific circuit requirements and thermal constraints.

Q: Is the SR010 still in production?

A: Yes, SR010 maintains Active product status with 941 pcs in current inventory. However, multiple Active alternatives with higher current ratings and extended temperature ranges are available from established manufacturers including onsemi, Diodes Incorporated, Vishay, and Comchip Technology.
