MMBD4448HADW-TP Equivalent & Substitute Parts

Part Overview

The MMBD4448HADW-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as a 2 Pair Common Anode design in a 6-TSSOP (SOT-363) surface mount package. This component is rated for 80 V DC reverse voltage with 250 mA average rectified current per diode and features fast recovery characteristics with a 4 ns reverse recovery time. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization requires alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMBD4448HADW-TP is permitted with parts that maintain identical electrical performance across all critical parameters. The substitution logic is based on the following key parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) (per Diode): 250 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 4 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 70 V
• Diode Configuration: 2 Pair Common Anode
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount
• Supplier Device Package: SOT-363

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed below meet these criteria and are therefore direct parametric equivalents suitable for pin-for-pin replacement in applications designed for the MMBD4448HADW-TP.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are parametric equivalents of the MMBD4448HADW-TP and are suitable for direct replacement in applications requiring a general-purpose diode array with 80 V reverse voltage rating and 250 mA average rectified current per diode in a 6-TSSOP surface mount package.

Selection Criteria Based on Provided Data:

1. Product Status: All parts (primary and substitutes) maintain Active production status, ensuring continued availability and supply chain stability.

2. Compliance Certification: All parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated markets.

3. Moisture Sensitivity: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage, handling, or assembly processes.

4. Electrical Performance: All substitute parts deliver identical electrical characteristics across reverse voltage, forward voltage, rectified current, and reverse recovery time specifications.

5. Package Compatibility: All parts utilize the 6-TSSOP (SOT-363) surface mount package, ensuring mechanical and thermal compatibility with existing PCB designs and assembly processes.

Selection between the primary part and substitutes may be based on inventory availability, supplier lead times, or procurement cost optimization, as all parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can MMBD4448HADW-7-F and MMBD4448HAQW-7-F be used interchangeably with MMBD4448HADW-TP?

A: Yes. Both Diodes Incorporated parts are parametric equivalents with identical electrical specifications, package configuration, and compliance certifications. Pin-for-pin replacement is supported without circuit modification.

Q: What is the significance of the different manufacturer part number suffixes (-TP, -7-F)?

A: The suffixes indicate packaging and tape configuration variants. The -TP designation indicates Tape & Reel packaging from Micro Commercial Co, while -7-F indicates Tape & Reel packaging from Diodes Incorporated. All variants use the same 6-TSSOP (SOT-363) package and are mechanically compatible.

Q: Are there any temperature range differences between the primary part and substitutes?

A: The primary part MMBD4448HADW-TP specifies a maximum junction operating temperature of 150°C. The substitute parts MMBD4448HADW-7-F and MMBD4448HAQW-7-F specify an operating temperature range of -65°C to 150°C. Both specifications support the same maximum operating temperature, ensuring thermal compatibility in all applications.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Compliance certifications are identical across all listed parts.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: Voltage - DC Reverse (80 V), Current - Average Rectified (250 mA per diode), Voltage - Forward (1.25 V @ 150 mA), Reverse Recovery Time (4 ns), Current - Reverse Leakage (100 nA @ 70 V), and Diode Configuration (2 Pair Common Anode). All listed substitutes match these parameters exactly.

Q: Is the 6-TSSOP package identical across all listed parts?

A: Yes. All parts use the 6-TSSOP (SC-88, SOT-363) surface mount package with identical pin configuration, footprint, and thermal characteristics. PCB layout and assembly processes require no modification when substituting between listed parts.

Q: What inventory levels are available for each part?

A: MMBD4448HADW-TP (Micro Commercial Co): 995 Pcs. MMBD4448HADW-7-F (Diodes Incorporated): 33,180 Pcs. MMBD4448HAQW-7-F (Diodes Incorporated): 1,415 Pcs. Inventory levels may change; current availability should be confirmed with suppliers.
