Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR10H100CT are categorized based on electrical and mechanical compatibility within the following parameters:

Direct Substitutes maintain identical electrical specifications: 100 V reverse voltage, 5 A average rectified current per diode, 730 mV forward voltage at 5 A, and TO-220-3 package configuration. These parts are pin-compatible and functionally interchangeable.

Similar Substitutes share the same reverse voltage (100 V), diode configuration (1 pair common cathode), and Schottky technology but feature higher current ratings (10 A or 15 A per diode). These parts are suitable for applications where the original 5 A rating is insufficient or where design margin is required. Package variations (TO-220-3 or TO-252-4 DPAK) may apply.

Parametric Equivalents match all critical electrical parameters (100 V, 5 A, 730 mV forward voltage, fast recovery) and package type (TO-220-3) but originate from different manufacturers. These provide direct functional replacement with active product status.

Substitution eligibility is determined by:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io) (per Diode): ≥5 A
• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-3 or compatible surface-mount variant

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Active Status):

STPS10H100CT (STMicroelectronics) is the preferred parametric equivalent. This part maintains identical electrical specifications (100 V, 5 A, 730 mV forward voltage) and TO-220-3 package configuration as the MBR10H100CT. The component is active, ROHS3 compliant, and available in high inventory (25,110 pcs). This selection eliminates design modification and provides regulatory compliance.

MBR10H100CT-E3/45 (Vishay General Semiconductor - Diodes Division) is a direct substitute with active status and ROHS3 compliance. Forward voltage is 760 mV at 5 A, representing a 30 mV increase from the original specification. This part is suitable for applications where this voltage differential does not impact circuit performance. Inventory availability is 3,650 pcs.

For Upgraded Current Rating (Same Package, Active Status):

SDT30A100CT (Diodes Incorporated) provides 15 A average rectified current per diode while maintaining 100 V reverse voltage and TO-220-3 package. Forward voltage is 730 mV at 15 A. This part is ROHS3 compliant and active, with 4,050 pcs in inventory. Selection is appropriate for designs requiring higher current capacity or improved thermal margin.

For Surface-Mount or Higher Current Applications:

MPE-220AVL and MPE-220AVR (Sanken Electric USA Inc.) offer 10 A and 20 A ratings respectively in TO-252-4 DPAK package. These parts are suitable for space-constrained designs or applications requiring higher current handling. Both are RoHS compliant and active. Forward voltage is 850 mV at rated current, representing a 120 mV increase from the original specification at 5 A operation.

MPE-220A (Sanken Electric USA Inc.) provides 10 A rating in TO-220-3 package, maintaining through-hole mounting compatibility. This part is RoHS compliant and active.

Frequently Asked Questions (FAQ)

Q: Can STPS10H100CT directly replace MBR10H100CT without circuit modification?

A: Yes. STPS10H100CT maintains identical electrical parameters (100 V reverse voltage, 5 A average rectified current, 730 mV forward voltage at 5 A) and TO-220-3 package configuration. Pin compatibility is confirmed. No circuit modification is required.

Q: What is the difference between MBR10H100CT-E3/45 and STPS10H100CT?

A: Both are direct substitutes with identical voltage and current ratings. MBR10H100CT-E3/45 exhibits 760 mV forward voltage at 5 A compared to 730 mV for STPS10H100CT, a 30 mV difference. STPS10H100CT offers higher inventory availability (25,110 pcs vs. 3,650 pcs). Selection depends on forward voltage tolerance requirements and supply chain considerations.

Q: Can I use SDT30A100CT as a substitute if my circuit only requires 5 A?

A: Yes. SDT30A100CT is rated for 15 A average rectified current per diode, exceeding the 5 A requirement of the original MBR10H100CT. The part maintains 100 V reverse voltage and TO-220-3 package. Operating at 5 A within a 15 A rated component provides design margin and improved thermal performance. Forward voltage is 730 mV at 15 A operation.

Q: What is the difference between TO-220-3 and TO-252-4 DPAK packages?

A: TO-220-3 is a through-hole package with three leads suitable for traditional PCB mounting. TO-252-4 DPAK is a surface-mount package with three leads plus a tab for enhanced thermal dissipation. DPAK packages require surface-mount assembly equipment and PCB redesign. Selection depends on manufacturing capability and thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: The original MBR10H100CT is RoHS non-compliant. All recommended substitutes (STPS10H100CT, MBR10H100CT-E3/45, SDT30A100CT, MPE-220A, MPE-220AVL, MPE-220AVR) are RoHS3 or RoHS compliant, meeting current regulatory requirements for new designs and production.

Q: What is the significance of forward voltage differences between substitutes?

A: Forward voltage affects power dissipation and circuit performance. MBR10H100CT and STPS10H100CT specify 730 mV at 5 A. MBR10H100CT-E3/45 specifies 760 mV at 5 A (30 mV higher). Sanken parts (MPE series) specify 850 mV at rated current. Higher forward voltage increases power loss in the diode. Selection depends on thermal budget and circuit tolerance for voltage drop variation.

Q: Can I substitute a higher-current-rated part in a 5 A application?

A: Yes. Higher-current-rated parts (SDT30A100CT at 15 A, MPE-220A at 10 A, MPE-220AVR at 20 A) are suitable for 5 A applications. The component operates below its maximum rating, providing design margin and improved reliability. Thermal performance improves due to lower junction temperature at reduced current. Package compatibility must be verified for PCB integration.

Q: What inventory considerations apply to substitute selection?

A: STPS10H100CT offers the highest inventory availability (25,110 pcs), ensuring supply continuity. SDT30A100CT (4,050 pcs), MPE-220AVR (946 pcs), and MPE-220AVL (900 pcs) provide adequate stock for production requirements. MBR10H100CT-E3/45 (3,650 pcs) and MPE-220A (694 pcs) are available but with lower inventory levels. Long-term supply planning should account for these quantities.
