Substitute Part Grouping Explanation

Substitution of the DMN2400UFD-7 is determined by electrical and mechanical parameter equivalence within the N-Channel MOSFET category. The following parameters establish substitution eligibility:

Electrical Parameters (Must Match):

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 20V
• Current - Continuous Drain (Id) @ 25°C: 900mA
• Rds On (Max) @ Id, Vgs: 600mOhm @ 200mA, 4.5V
• Power Dissipation (Max): 400mW
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package / Case: 3-UDFN
• Mounting Type: Surface Mount
• Supplier Device Package: X1-DFN1212-3

Compliance Parameters (Must Match):

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

The DMN2450UFD-7 meets all specified electrical, mechanical, and compliance requirements and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The DMN2450UFD-7 is the direct substitute for the DMN2400UFD-7. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications, mechanical package dimensions, and compliance certifications.

Selection Basis:

The DMN2450UFD-7 is recommended for new designs and ongoing production applications. This part carries an "Active" product status, ensuring long-term availability and continued manufacturer support. The DMN2400UFD-7, designated as "Not For New Designs," should be replaced with the DMN2450UFD-7 in all new circuit development and production planning.

Both parts are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Packaging availability differs between the two parts: the DMN2400UFD-7 is supplied in Tape & Reel format, while the DMN2450UFD-7 is available in Cut Tape and Digi-Reel® formats. Selection between packaging options should be based on assembly line requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can the DMN2450UFD-7 be used as a direct replacement for the DMN2400UFD-7 in existing designs?

A: Yes. The DMN2450UFD-7 is electrically and mechanically equivalent to the DMN2400UFD-7. All critical parameters including Vdss, Id, Rds On, power dissipation, and operating temperature range are identical. The devices share the same 3-UDFN package and X1-DFN1212-3 supplier package designation.

Q: What is the difference between the two parts?

A: The primary differences are product status and packaging format. The DMN2400UFD-7 is designated "Not For New Designs" and supplied in Tape & Reel packaging. The DMN2450UFD-7 is an active product available in Cut Tape and Digi-Reel® formats. Gate charge specifications differ slightly (500 nC versus 0.7 nC @ 4.5V) and input capacitance differs (37 pF versus 52 pF @ 16V), but these variations do not affect substitution eligibility for the specified electrical and mechanical parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the DMN2400UFD-7 and DMN2450UFD-7 are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Both parts meet the same regulatory and environmental standards.

Q: Which packaging format should be selected?

A: Packaging selection depends on assembly requirements. The DMN2400UFD-7 is supplied in Tape & Reel (TR) format. The DMN2450UFD-7 is available in Cut Tape (CT) and Digi-Reel® formats. Verify compatibility with your pick-and-place equipment and supply chain logistics before finalizing the packaging selection.

Q: Is the DMN2450UFD-7 suitable for new product designs?

A: Yes. The DMN2450UFD-7 carries an "Active" product status, making it the appropriate choice for new circuit development. The DMN2400UFD-7 should not be used in new designs due to its "Not For New Designs" designation.
