DMN2046U-13 Equivalent & Substitute Parts

Part Overview

The DMN2046U-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 20V drain-to-source voltage with 3.4A continuous drain current at 25°C. The device is packaged in SOT-23-3 surface mount configuration and dissipates a maximum of 760mW. This part is classified as Active product status and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. The DMN2046U-13 is supplied in Tape & Reel (TR) packaging; alternative packaging formats of the same base device may be required for different procurement or assembly workflows.

Substitute Part Grouping Explanation

Substitute parts for the DMN2046U-13 are identified based on electrical parameter equivalence and mechanical compatibility. The substitution criteria are strictly limited to the following parameters:

• FET Type and Technology: N-Channel MOSFET (Metal Oxide)
• Voltage Rating (Vdss): 20V
• Current Rating (Id @ 25°C): 3.4A (Ta)
• On-State Resistance (Rds On): 72mOhm @ 3.6A, 4.5V
• Threshold Voltage (Vgs(th)): 1.4V @ 250µA
• Gate Charge (Qg): 3.8nC @ 4.5V
• Maximum Gate Voltage (Vgs): ±12V
• Input Capacitance (Ciss): 292pF @ 10V
• Power Dissipation: 760mW (Ta)
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

Substitute parts must maintain identical electrical specifications and the same physical package footprint. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and is determined by procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

The DMN2046U-7 is a direct electrical and mechanical equivalent to the DMN2046U-13. Both devices are manufactured by Diodes Incorporated and share the identical base product number DMN2046. All electrical parameters, including voltage rating, current capacity, on-state resistance, threshold voltage, gate charge, and capacitance specifications, are identical.

Both parts maintain Active product status and carry ROHS3 compliance and REACH Unaffected designation. Moisture sensitivity level is rated at MSL 1 (Unlimited) for both variants, indicating no special moisture handling requirements during storage or assembly.

The sole difference between these parts is the packaging format: DMN2046U-13 is supplied in Tape & Reel (TR) format, while DMN2046U-7 is supplied in Cut Tape (CT) and Digi-Reel® format. This distinction affects procurement and automated assembly workflows but does not alter electrical performance or physical footprint compatibility.

Selection between these variants is determined by assembly equipment capability and supply chain requirements rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can DMN2046U-7 be used as a direct replacement for DMN2046U-13 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, including Vdss, Id, Rds On, Vgs(th), gate charge, and operating temperature range, are identical. The SOT-23-3 package footprint is the same for both variants.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel and Cut Tape are packaging formats that affect how components are supplied and handled during assembly. TR format uses continuous tape on a reel for high-volume automated pick-and-place assembly. CT format uses individual tape segments and is suitable for lower-volume or manual assembly workflows. Electrical and mechanical specifications are unchanged between formats.

Q: Are there any compliance or regulatory differences between DMN2046U-13 and DMN2046U-7?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). ECCN and HTSUS classifications are identical.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The physical footprint and electrical characteristics are identical. No circuit modifications or PCB layout changes are required when substituting between these variants.

Q: What determines which packaging format to select?

A: Selection is based on assembly process requirements and supply chain logistics. Tape & Reel format is standard for high-volume automated assembly lines. Cut Tape format is used for lower-volume production, manual assembly, or when component quantities are smaller than full reel quantities.

Q: Is the Digi-Reel® format compatible with standard tape-and-reel equipment?

A: Digi-Reel® is a proprietary packaging format. Compatibility with specific assembly equipment should be verified with equipment specifications. Standard Cut Tape format is compatible with manual assembly and some semi-automated systems.

Q: Are there inventory or lead time considerations when choosing between these variants?

A: Inventory levels differ between variants. DMN2046U-13 (TR) has 901 pieces in stock, while DMN2046U-7 (CT) has 176,200 pieces in stock. Lead time and availability may vary based on current supply conditions.
