Substitute Part Grouping Explanation

Substitution of the CSD23201W10 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• FET Type: P-Channel topology
• Drain to Source Voltage (Vdss): 12V minimum rating
• Continuous Drain Current (Id): 2.2A or greater at 25°C
• Power Dissipation: 1W or greater
• Operating Temperature Range: -55°C to 150°C or wider
• Gate Drive Voltage Compatibility: Vgs (Max) of -6V or lower

Mechanical Equivalence Criteria:

• Package Type: 4-DSBGA (1x1) surface mount
• Mounting Type: Surface mount
• Pin configuration: 4-pin UFBGA/DSBGA footprint compatibility

Compliance Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1 or better
• REACH Unaffected status

The CSD23202W10 meets all substitution criteria and is classified as an Active product, providing improved long-term availability compared to the Obsolete CSD23201W10.

Parameter Comparison

Engineering Selection Recommendations

The CSD23202W10 is the direct substitute for the obsolete CSD23201W10. Both devices share identical electrical ratings for Vdss, Id, power dissipation, and operating temperature range. Both are housed in the same 4-DSBGA (1x1) surface mount package with identical pin configuration and footprint compatibility.

The CSD23202W10 offers improved performance characteristics: lower on-resistance (53 mOhm versus 82 mOhm at 500mA, 4.5V) and lower gate threshold voltage (900 mV versus 1V at 250 µA). These improvements result in reduced power losses and faster switching response.

The CSD23202W10 is classified as Active, ensuring long-term availability and continued manufacturing support. Both parts maintain identical compliance certifications: ROHS3 Compliant, MSL Level 1, and REACH Unaffected status.

For new designs or production transitions from the obsolete CSD23201W10, the CSD23202W10 is the recommended substitute without design modification requirements.

Frequently Asked Questions (FAQ)

Q: Can the CSD23202W10 be used as a direct replacement for the CSD23201W10 without circuit modification?

A: Yes. Both devices are P-Channel MOSFETs with identical Vdss (12V), Id (2.2A), power dissipation (1W), operating temperature range (-55°C to 150°C), and package type (4-DSBGA 1x1). Pin configuration and footprint are identical. The CSD23202W10 exhibits improved electrical performance with lower on-resistance and lower gate threshold voltage, making it a superior substitute.

Q: What is the difference in on-resistance between these two parts?

A: The CSD23201W10 has a maximum on-resistance of 82 mOhm at 500mA and 4.5V gate-source voltage. The CSD23202W10 has a maximum on-resistance of 53 mOhm under identical conditions. This 29 mOhm reduction results in lower power dissipation during operation.

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

A: Both parts use the 4-DSBGA (1x1) surface mount package. The CSD23202W10 is available in Cut Tape (CT) and Digi-Reel® packaging, as well as Tape & Reel (TR) format. Packaging availability should be verified with the supplier for specific procurement requirements.

Q: What is the product status difference, and why does it matter?

A: The CSD23201W10 is classified as Obsolete, indicating Texas Instruments has discontinued manufacturing and will not guarantee future availability. The CSD23202W10 is classified as Active, meaning it is currently manufactured and supported. For ongoing production and new designs, the Active CSD23202W10 ensures supply chain continuity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CSD23201W10 and CSD23202W10 are ROHS3 Compliant, have Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status. Compliance certifications are identical.

Q: What are the gate charge differences between these parts?

A: The CSD23201W10 has a maximum gate charge of 2.4 nC at 4.5V. The CSD23202W10 has a maximum gate charge of 3.8 nC at 4.5V. The higher gate charge in the CSD23202W10 reflects its improved performance characteristics and lower on-resistance.

Q: Is the input capacitance the same for both devices?

A: No. The CSD23201W10 has a maximum input capacitance of 325 pF at 6V. The CSD23202W10 has a maximum input capacitance of 512 pF at 6V. The higher input capacitance in the CSD23202W10 is associated with its improved on-resistance performance.
