Substitute Part Grouping Explanation

Substitute parts for the DMP4065S-13 are identified within the DMP4065 base product family. Substitution is valid when the following electrical and mechanical parameters are identical:

Drain to Source Voltage (Vdss): 40V
Continuous Drain Current (Id) @ 25°C: 2.4A (Ta)
On-State Drain Resistance (Rds On): 80mOhm @ 4.2A, 10V
Gate Threshold Voltage (Vgs(th)): 3V @ 250µA
Gate Charge (Qg): 12.2nC @ 10V
Maximum Gate-Source Voltage (Vgs): ±20V
Input Capacitance (Ciss): 587pF @ 20V
Power Dissipation: 720mW (Ta)
Operating Temperature Range: -55°C to 150°C (TJ)
Package Type: SOT-23-3 (TO-236-3, SC-59)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

The primary difference between substitute parts lies in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability. All substitute parts maintain identical electrical performance and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can DMP4065S-7 be used as a direct replacement for DMP4065S-13?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: DMP4065S-13 is supplied in Tape & Reel (TR) format, while DMP4065S-7 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly equipment compatibility and quantity requirements.

Q: What is the difference between DMP4065SQ-7 and DMP4065S-7?

A: Both parts have identical electrical specifications and operating characteristics. DMP4065SQ-7 is supplied in Tape & Reel (TR) format, while DMP4065S-7 is supplied in Cut Tape (CT) & Digi-Reel® format. The packaging format determines suitability for specific assembly processes.

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

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

Q: Do these parts have different thermal performance?

A: No. All three parts have identical maximum power dissipation of 720mW (Ta) and the same operating temperature range of -55°C to 150°C (TJ). Thermal performance is equivalent across all variants.

Q: What is the significance of the "-13," "-7," and "SQ-7" suffixes?

A: These suffixes denote different packaging and distribution formats within the DMP4065 base product family. The electrical and mechanical specifications remain constant. The suffix indicates the supplier device package configuration and tape format.
