Substitute Part Grouping Explanation

Substitution of the CSD75205W1015 is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Configuration: 2 P-Channel (Dual)
• Drain to Source Voltage (Vdss): 20V
• Package / Case: 6-UFBGA, DSBGA
• Supplier Device Package: 6-DSBGA (1x1.5)
• FET Feature: Logic Level Gate
• Technology: MOSFET (Metal Oxide)
• Operating Temperature Range: -55°C to 150°C (TJ)

Allowable Parameter Variations: Substitute parts may exceed the following specifications of the CSD75205W1015 without compromising compatibility:

• Current - Continuous Drain (Id) @ 25°C: May be equal to or greater than 1.2A
• Rds On (Max) @ Id, Vgs: May be equal to or lower than 120mOhm
• Vgs(th) (Max) @ Id: May be equal to or lower than 850mV
• Gate Charge (Qg) (Max) @ Vgs: May be equal to or higher than 2.2nC
• Input Capacitance (Ciss) (Max) @ Vds: May be equal to or higher than 265pF
• Power - Max: Must remain at or above 750mW

The CSD75208W1015 qualifies as a direct substitute based on these criteria.

Engineering Selection Recommendations

The CSD75208W1015 is the qualified substitute for the obsolete CSD75205W1015. Selection of this substitute is supported by the following factors:

Product Status: The CSD75208W1015 maintains active product status with Texas Instruments, ensuring continued availability and manufacturing support. The CSD75205W1015 is classified as obsolete, making the CSD75208W1015 the appropriate choice for new designs and ongoing production.

Compliance and Certifications: Both parts maintain identical RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.21.0095, ensuring regulatory equivalence.

Electrical Performance: The CSD75208W1015 provides enhanced electrical characteristics compared to the CSD75205W1015. The increased continuous drain current (1.6A versus 1.2A) and reduced on-resistance (68mOhm versus 120mOhm) represent performance improvements that maintain backward compatibility while offering superior thermal and efficiency characteristics in applications.

Package Compatibility: Both parts utilize identical 6-DSBGA (1x1.5) surface mount packaging, ensuring direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the CSD75208W1015 be used as a direct replacement for the CSD75205W1015 in existing designs?

A: Yes. The CSD75208W1015 is electrically and mechanically compatible with the CSD75205W1015. Both devices share identical package geometry (6-DSBGA 1x1.5), voltage rating (20V Vdss), configuration (dual P-channel), and operating temperature range (-55°C to 150°C). The CSD75208W1015 provides equal or superior performance across all critical parameters.

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

A: The primary differences are product status and electrical performance. The CSD75205W1015 is obsolete, while the CSD75208W1015 is active. The CSD75208W1015 offers higher continuous drain current (1.6A versus 1.2A), lower on-resistance (68mOhm versus 120mOhm), and slightly higher gate charge (2.5nC versus 2.2nC) and input capacitance (410pF versus 265pF).

Q: Are there any thermal or power dissipation concerns when substituting the CSD75208W1015 for the CSD75205W1015?

A: Both parts are rated for identical maximum power dissipation (750mW) and operating temperature range (-55°C to 150°C TJ). The CSD75208W1015's lower on-resistance (68mOhm versus 120mOhm) typically results in reduced power dissipation during operation, providing a thermal advantage in most applications.

Q: Do both parts require identical PCB layout and design considerations?

A: Yes. Both parts use the same 6-DSBGA (1x1.5) surface mount package, requiring identical PCB footprints, trace routing, and layout considerations. No design modifications are necessary for substitution.

Q: What is the availability status of each part?

A: The CSD75205W1015 is obsolete with limited remaining inventory (4042 pieces). The CSD75208W1015 is an active product with significantly higher inventory availability (30549 pieces), ensuring reliable supply chain access for current and future production requirements.

Q: Are compliance certifications identical between these parts?

A: Yes. Both parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN (EAR99) and HTSUS (8541.21.0095) classifications.
