Substitute Part Grouping Explanation

Substitution within the DMP4065 series is determined by electrical parameter equivalence and mechanical compatibility. All substitute parts maintain identical electrical specifications across the following critical parameters:

Drain to Source Voltage (Vdss): 40V
Continuous Drain Current (Id): 2.4A @ 25°C
On-Resistance (Rds On): 80mOhm @ 4.2A, 10V
Gate Threshold Voltage: 3V @ 250µA
Gate Charge: 12.2nC @ 10V
Input Capacitance: 587pF @ 20V
Power Dissipation: 720mW
Operating Temperature: -55°C to 150°C
Package: SOT-23-3 (TO-236-3, SC-59)

Substitutes differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and manufacturing date code designations (-13 versus -7 suffix). These variations do not affect electrical performance or circuit functionality.

Engineering Selection Recommendations

All substitute parts within the DMP4065 series maintain full electrical and mechanical compatibility with the DMP4065SQ-13. Selection between equivalent parts is determined by supply chain availability and packaging format requirements:

DMP4065SQ-13 (Tape & Reel, -13 date code): Primary specification reference with 1071 units in stock.

DMP4065S-13 (Tape & Reel, -13 date code): Identical electrical performance and date code designation with 9834 units in stock. Direct substitution for DMP4065SQ-13 with higher inventory availability.

DMP4065S-7 (Cut Tape & Digi-Reel, -7 date code): Identical electrical performance with alternative packaging format. Highest inventory availability at 155100 units. Suitable for applications requiring cut tape or Digi-Reel format.

DMP4065SQ-7 (Tape & Reel, -7 date code): Identical electrical performance with alternative date code designation. 3150 units in stock.

All parts are Active product status, ROHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating. No functional or compliance differences exist between substitute options.

Frequently Asked Questions (FAQ)

Q: Can DMP4065S-13 replace DMP4065SQ-13 in production?

A: Yes. Both parts are electrically identical across all specified parameters and share the same SOT-23-3 package. The suffix difference (-S versus -SQ) does not affect electrical performance or circuit functionality. Both are supplied in Tape & Reel format.

Q: What is the difference between DMP4065S-7 and DMP4065SQ-13?

A: The electrical specifications are identical. The primary difference is packaging format: DMP4065S-7 is supplied in Cut Tape & Digi-Reel format, while DMP4065SQ-13 is supplied in Tape & Reel format. The date code suffix (-7 versus -13) indicates manufacturing date code designation and does not affect performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts in the DMP4065 series carry ROHS3 compliance certification and REACH Unaffected status.

Q: Can I use DMP4065S-7 in a design specified for DMP4065SQ-13?

A: Yes, from an electrical and mechanical standpoint. The SOT-23-3 package pinout and electrical characteristics are identical. Packaging format (Cut Tape versus Tape & Reel) affects only procurement and assembly processes, not circuit performance.

Q: What is the moisture sensitivity level for all DMP4065 variants?

A: All variants carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any temperature or power dissipation differences between substitutes?

A: No. All substitute parts operate across the identical temperature range (-55°C to 150°C) and maintain the same maximum power dissipation rating of 720mW.

Q: Which substitute part has the highest inventory availability?

A: DMP4065S-7 has the highest inventory at 155100 units in stock.
