Substitute Part Grouping Explanation

Substitution of the MMBD4448HTMQ-7-F is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• 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
• Operating Temperature - Junction: -65°C ~ 150°C
• Diode Configuration: 3 Independent
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part MMBD4448HTM-7-F meets all electrical specifications and mechanical requirements identical to the main part. The primary distinction is packaging format and product status, with the substitute available in active production status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MMBD4448HTM-7-F is a direct parametric equivalent to the MMBD4448HTMQ-7-F across all electrical and mechanical specifications. All critical performance parameters, including voltage ratings, current ratings, switching characteristics, and temperature operating range, are identical.

The MMBD4448HTM-7-F carries active product status from Diodes Incorporated, ensuring ongoing availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments.

The primary distinction between the two parts is packaging format. The MMBD4448HTMQ-7-F is supplied in bulk packaging, while the MMBD4448HTM-7-F is supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical or thermal performance.

Selection of the MMBD4448HTM-7-F is appropriate for new designs, production continuity, and replacement applications where the obsolete MMBD4448HTMQ-7-F is currently specified.

Frequently Asked Questions (FAQ)

Q: Are the MMBD4448HTMQ-7-F and MMBD4448HTM-7-F electrically identical?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. All voltage ratings, current ratings, switching characteristics, and temperature operating ranges are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The MMBD4448HTMQ-7-F is supplied in bulk packaging, while the MMBD4448HTM-7-F is supplied in Tape & Reel (TR) format. The MMBD4448HTM-7-F also carries active product status, whereas the MMBD4448HTMQ-7-F is classified as obsolete.

Q: Can I use MMBD4448HTM-7-F as a direct replacement in existing assemblies?

A: Yes. The MMBD4448HTM-7-F is a direct parametric equivalent. Both parts use the same SOT-23-6 package and have identical pinout, electrical performance, and thermal characteristics. Substitution is valid for both new production and field replacement applications.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not affect the electrical performance, reliability, or thermal characteristics of the diode array. The component itself is identical regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both the MMBD4448HTMQ-7-F and MMBD4448HTM-7-F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the MMBD4448HTMQ-7-F classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this specific part number variant. The MMBD4448HTM-7-F remains in active production and is the recommended source for current procurement.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. Standard storage conditions are sufficient for these components.
