Substitute Part Grouping Explanation

Substitute parts for the DMP3015LSSQ-13 are qualified based on electrical parameter equivalence and mechanical compatibility. The substitution logic is structured around the following critical parameters that must remain constant or within acceptable tolerance:

Electrical Equivalence Criteria:

• Drain-to-Source Voltage (Vdss): 30V minimum
• Continuous Drain Current (Id) @ 25°C: 13A minimum
• FET Type: P-Channel
• Technology: MOSFET (Metal Oxide)
• Operating Temperature Range: -55°C to 150°C (TJ)
• Power Dissipation: 2.5W (Ta)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Supplier Device Package: 8-SO or 8-SOIC

Compliance & Certification Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

Substitute parts meeting all electrical, mechanical, and compliance criteria are classified as direct equivalents. Variations in secondary parameters such as Rds On, Gate Charge, and Input Capacitance are documented to support circuit performance analysis but do not disqualify substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DMP3015LSSQ-13, DMP3015LSS-13, and FDS6679AZ—maintain Active product status and full compliance with RoHS3, REACH, and export control requirements (ECCN EAR99). All devices are rated for identical voltage, current, power dissipation, and operating temperature specifications, confirming electrical equivalence for primary circuit function.

DMP3015LSS-13 (Diodes Incorporated): This part is a parametric equivalent to the DMP3015LSSQ-13, differing only in packaging designation (8-SOP versus 8-SO). Both are manufactured by Diodes Incorporated and share identical electrical specifications. This substitute provides direct compatibility with equivalent inventory availability (47,600 units in stock).

FDS6679AZ (onsemi): This part is a manufacturer-recommended equivalent from onsemi's PowerTrench® series. It meets all primary electrical and mechanical requirements with identical Vdss, Id, power dissipation, and operating temperature range. Secondary parameter variations include lower Rds On (9.3 mOhm versus 11 mOhm), higher Gate Charge (96 nC versus 60.4 nC), and higher Input Capacitance (3845 pF versus 2748 pF). These variations reflect different semiconductor process technology but do not affect functional compatibility in standard P-channel switching applications. The FDS6679AZ offers superior on-resistance performance, reducing conduction losses in power-sensitive designs.

Selection between these equivalents is determined by supply chain availability, cost considerations, and secondary performance requirements. All three parts are suitable for direct substitution in applications designed for the DMP3015LSSQ-13.

Frequently Asked Questions (FAQ)

Q: Can DMP3015LSS-13 be used as a direct replacement for DMP3015LSSQ-13?

A: Yes. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications including Vdss (30V), Id (13A), Rds On (11 mOhm @ 13A, 10V), and operating temperature range (-55°C to 150°C). The packaging designation difference (8-SOP versus 8-SO) does not affect electrical function or PCB footprint compatibility, as both conform to the 8-SOIC (0.154", 3.90mm Width) standard.

Q: What are the key differences between FDS6679AZ and DMP3015LSSQ-13?

A: The FDS6679AZ is manufactured by onsemi using PowerTrench® technology and offers improved on-resistance performance (9.3 mOhm versus 11 mOhm at 13A, 10V). However, it exhibits higher Gate Charge (96 nC versus 60.4 nC) and higher Input Capacitance (3845 pF versus 2748 pF). These secondary parameter differences reflect process technology variations but do not prevent functional substitution. The lower Rds On reduces conduction losses, making FDS6679AZ advantageous in applications where thermal management or efficiency is critical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts are packaged in 8-SOIC (0.154", 3.90mm Width) surface mount configuration with identical pin assignments for P-channel MOSFET operation. PCB layout and footprint modifications are not required for substitution.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. DMP3015LSSQ-13, DMP3015LSS-13, and FDS6679AZ are all RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All three maintain Moisture Sensitivity Level 1 (Unlimited) rating. Compliance documentation is equivalent across all three parts.

Q: Which substitute part should be selected for maximum efficiency?

A: FDS6679AZ provides the lowest on-resistance (9.3 mOhm), resulting in reduced conduction losses and lower junction temperature rise during continuous operation at rated current. This characteristic is beneficial in applications where thermal dissipation or power efficiency is a design constraint. However, the higher Gate Charge may require driver circuit optimization for switching speed applications.

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

A: Yes. All three parts meet identical primary electrical specifications (Vdss, Id, power dissipation, operating temperature) and are packaged in the same 8-SOIC footprint. No circuit modifications are required for substitution. Secondary parameter variations (Rds On, Gate Charge, Input Capacitance) do not necessitate design changes in standard switching applications but may be considered in performance-optimized designs.

Q: What inventory considerations apply to these substitutes?

A: DMP3015LSSQ-13 has 3,079 units in stock, DMP3015LSS-13 has 47,600 units in stock, and FDS6679AZ has 50,200 units in stock. DMP3015LSS-13 and FDS6679AZ offer significantly higher availability, supporting extended production runs and reducing supply chain risk.
