CSD75204W15 Equivalent & Substitute Parts

Part Overview

The CSD75204W15 is a dual P-channel MOSFET array manufactured by Texas Instruments as part of the NexFET™ series. This device integrates two P-channel MOSFETs in a 9-DSBGA surface mount package, designed for logic-level gate switching applications with a continuous drain current rating of 3A and maximum power dissipation of 700mW.

The CSD75204W15 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this part is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSD75204W15 is determined by the following critical parameters:

Configuration Match: The substitute must maintain a 2 P-channel dual MOSFET configuration in the same 9-DSBGA package to ensure mechanical and electrical compatibility with existing PCB layouts and solder reflow processes.

Current Rating: The substitute must support a continuous drain current (Id) equal to or greater than 3A at 25°C. This ensures the substitute can handle the same or higher current loads without thermal derating.

Gate Threshold Voltage (Vgs(th)): The substitute must maintain logic-level gate operation characteristics compatible with standard digital control signals. The threshold voltage must remain within acceptable ranges for the intended switching application.

Thermal and Power Characteristics: The substitute must support the same maximum power dissipation of 700mW and operate across the full temperature range of -55°C to 150°C (TJ).

Package and Mounting: The substitute must use the 9-DSBGA surface mount package to maintain PCB footprint compatibility and assembly process alignment.

Compliance: The substitute must maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status to meet regulatory and supply chain requirements.

Engineering Selection Recommendations

CSD75207W15 as Primary Substitute

The CSD75207W15 is the manufacturer-recommended substitute for the CSD75204W15. This part maintains identical package geometry (9-DSBGA), configuration (dual P-channel), thermal operating range (-55°C to 150°C), and power rating (700mW). The CSD75207W15 provides enhanced performance with a continuous drain current rating of 3.9A, exceeding the original 3A specification, while maintaining logic-level gate operation.

Compliance and Availability

The CSD75207W15 holds active product status with Texas Instruments, ensuring long-term availability and supply chain stability. Both parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, meeting all regulatory requirements for industrial and commercial applications.

Parameter Considerations

The input capacitance (Ciss) of the CSD75207W15 is 595pF compared to 410pF in the CSD75204W15. This increase may affect switching speed in high-frequency applications; however, the gate charge remains comparable (3.7nC versus 3.9nC), indicating minimal impact on gate drive requirements. The threshold voltage increase from 900mV to 1.1V remains within acceptable logic-level gate operation parameters.

Frequently Asked Questions (FAQ)

Q: Can the CSD75207W15 directly replace the CSD75204W15 in existing designs?

A: Yes. Both parts share identical package geometry (9-DSBGA), configuration (dual P-channel), operating temperature range, and power rating. The CSD75207W15 provides higher continuous drain current (3.9A versus 3A), making it suitable for applications originally designed for the CSD75204W15.

Q: What is the difference in gate charge between these parts?

A: The CSD75204W15 has a gate charge of 3.9nC at 4.5V, while the CSD75207W15 has 3.7nC at 4.5V. This minor difference indicates comparable gate drive requirements and switching performance.

Q: How does the increased input capacitance of the CSD75207W15 affect circuit performance?

A: The CSD75207W15 has an input capacitance of 595pF compared to 410pF in the CSD75204W15. This increase may slightly reduce switching speed in high-frequency applications but does not prevent direct substitution. Circuit simulation or bench testing is appropriate for applications operating above 1MHz.

Q: Are both parts available in the same packaging options?

A: Both parts use the 9-DSBGA surface mount package. The CSD75207W15 is available in Cut Tape (CT) and Digi-Reel® packaging options, while the CSD75204W15 is obsolete. Standard surface mount assembly processes apply to both parts.

Q: Do these parts meet the same regulatory requirements?

A: Yes. Both the CSD75204W15 and CSD75207W15 are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Both parts meet EAR99 export classification and HTSUS code 8541.21.0095.

Q: Why is the CSD75204W15 obsolete?

A: The CSD75204W15 has been discontinued by Texas Instruments. The CSD75207W15 represents the active product line continuation with improved specifications and ongoing manufacturer support.
