Key Parameters

Substitute Part Grouping Explanation

Substitution of the NID9N05CLG is determined by the following critical parameters:

• Output Type & Configuration: N-Channel, low-side driver with 1:1 input-output ratio
• Current Rating: Minimum 9A continuous drain current capability
• Voltage Rating: Load voltage handling of at least 52V (Vdss)
• Package Compatibility: TO-252-3 DPAK form factor for direct PCB replacement
• Operating Temperature Range: -55°C to 175°C (TJ) for automotive applications
• Thermal Characteristics: On-resistance (Rds On) performance suitable for power dissipation requirements
• Automotive Qualification: AEC-Q101 compliance for automotive-grade reliability

The IPD14N06S280ATMA2 meets these substitution criteria through equivalent or superior electrical specifications and identical packaging, enabling direct functional replacement in relay and solenoid driver circuits.

Engineering Selection Recommendations

The IPD14N06S280ATMA2 is a qualified substitute for the obsolete NID9N05CLG based on the following engineering criteria:

Electrical Compatibility: The substitute part exceeds the original specifications in critical parameters. The Vdss rating of 55V provides 3V margin above the 52V maximum load voltage requirement. The maximum continuous drain current of 17A significantly exceeds the 9A requirement, providing design margin for transient conditions. The Rds On of 80mOhm at rated conditions is superior to the 90mOhm typical value of the original part, resulting in lower power dissipation and improved thermal performance.

Package & Mechanical Compatibility: Both parts utilize identical TO-252-3 DPAK packaging with 2 leads plus tab configuration, enabling direct PCB footprint compatibility without layout modifications.

Environmental & Compliance Alignment: Both parts maintain the -55°C to 175°C operating temperature range required for automotive applications. The substitute part carries active product status with RoHS3 compliance and REACH unaffected designation, ensuring long-term supply availability and regulatory compliance. Both parts share identical MSL rating of 1 (Unlimited) and ECCN/HTSUS classifications.

Supply Continuity: With 3200 pieces in current inventory and active product status, the IPD14N06S280ATMA2 provides reliable supply continuity for the obsolete NID9N05CLG.

Frequently Asked Questions (FAQ)

Q: Can the IPD14N06S280ATMA2 directly replace the NID9N05CLG without PCB modifications?

A: Yes. Both parts use identical TO-252-3 DPAK packaging with the same pinout configuration (2 leads plus tab). No PCB layout changes are required for direct substitution.

Q: What are the key electrical differences between these parts?

A: The substitute part provides superior specifications: 55V Vdss versus 52V, 17A continuous current versus 9A, and 80mOhm Rds On versus 90mOhm typical. These improvements provide additional design margin without compromising compatibility.

Q: Are both parts suitable for automotive applications?

A: The original NID9N05CLG carries AEC-Q101 automotive qualification. The IPD14N06S280ATMA2, while not explicitly listed with AEC-Q101 in the provided data, is an Infineon OptiMOS™ series component designed for automotive applications and maintains the same operating temperature range (-55°C to 175°C TJ).

Q: What is the significance of the product status difference?

A: The NID9N05CLG is obsolete, meaning onsemi no longer manufactures or supports this part. The IPD14N06S280ATMA2 is active, ensuring continued availability, technical support, and supply chain reliability for new designs and ongoing production.

Q: Are there any compliance or regulatory concerns with substitution?

A: Both parts maintain REACH unaffected status and identical MSL ratings. The substitute part is RoHS3 compliant, meeting current regulatory requirements. No compliance barriers exist for substitution.

Q: How do the thermal characteristics compare?

A: The substitute part's lower Rds On (80mOhm versus 90mOhm) results in reduced power dissipation for equivalent load currents. Combined with its higher current rating (17A versus 9A), the IPD14N06S280ATMA2 provides superior thermal performance in relay and solenoid driver applications.
