Substitute Part Grouping Explanation

Substitute parts for the DMP2045UQ-13 are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following matching criteria:

Electrical Parameters (Must Match):

• FET Type: P-Channel
• Drain-to-Source Voltage (Vdss): 20 V
• Continuous Drain Current (Id) @ 25°C: 4.3 A
• On-State Resistance (Rds On) @ 4A, 4.5V: 45 mOhm
• Gate Threshold Voltage (Vgs(th)) @ 250µA: 1 V
• Gate Charge (Qg) @ 4.5V: 6.8 nC
• Input Capacitance (Ciss) @ 10V: 634 pF
• Power Dissipation (Max): 800 mW
• Operating Temperature Range: -55°C to 150°C
• Maximum Gate Voltage (Vgs): ±8V

Mechanical Parameters (Must Match):

• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount
• Base Product Number: DMP2045

Compliance Parameters:

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

All substitute parts listed maintain identical electrical performance and are functionally interchangeable within the same circuit design. Packaging variations (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the DMP2045UQ-13. Selection among these alternatives is determined by packaging and supply requirements rather than electrical performance.

For Automotive Applications with AEC-Q101 Requirement: DMP2045UQ-13 and DMP2045UQ-7 are both qualified to AEC-Q101 automotive standards. These parts are suitable for applications requiring automotive-grade certification and traceability.

For General Industrial Applications: DMP2045U-13 and DMP2045U-7 provide identical electrical characteristics without automotive-grade designation. These parts are appropriate for non-automotive surface mount applications.

For Packaging Format Selection:

• Tape & Reel (TR) format: DMP2045UQ-13, DMP2045U-13
• Cut Tape (CT) & Digi-Reel® format: DMP2045U-7, DMP2045UQ-7

All parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can DMP2045U-13 be used as a direct replacement for DMP2045UQ-13 in automotive applications?

A: DMP2045U-13 shares identical electrical specifications with DMP2045UQ-13. However, DMP2045U-13 does not carry AEC-Q101 automotive qualification. Use DMP2045U-13 only in non-automotive applications or where automotive qualification is not required.

Q: What is the difference between DMP2045UQ-13 and DMP2045UQ-7?

A: Both parts are electrically identical and carry AEC-Q101 automotive qualification. The primary difference is packaging format: DMP2045UQ-13 is supplied in Tape & Reel (TR) format, while DMP2045UQ-7 is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on assembly line requirements.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the SOT-23-3 package (TO-236-3, SC-59), which defines identical pin configuration and PCB footprint. No layout modifications are required when substituting between these parts.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects only supply and handling logistics. Electrical characteristics remain identical regardless of packaging format.

Q: Which substitute part should be selected for high-volume production?

A: DMP2045U-7 offers the highest inventory availability (20,400 Pcs) in Cut Tape & Digi-Reel® format. For automotive applications, DMP2045UQ-7 provides equivalent availability (4,580 Pcs) with AEC-Q101 qualification in the same packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for both automotive and industrial applications.

Q: Can these parts be used interchangeably in existing designs without circuit modification?

A: Yes. All substitute parts maintain identical electrical parameters, operating temperature range, and power dissipation specifications. Direct substitution in existing circuit designs is supported without modification.
