Engineering Selection Recommendations

Primary Substitute: CSD25202W15

The CSD25202W15 is the direct substitute for the obsolete CSD25201W15. Both devices are manufactured by Texas Instruments within the NexFET™ series and share identical electrical ratings for voltage, current, and temperature operation. The CSD25202W15 is classified as Active product status, ensuring availability for current and future production requirements.

Compliance and Certification:

Both parts maintain ROHS3 compliance, MSL Level 1 (Unlimited moisture sensitivity), and REACH Unaffected status. No additional qualification or testing is required from a regulatory standpoint when transitioning from CSD25201W15 to CSD25202W15.

Performance Characteristics:

The CSD25202W15 demonstrates improved on-resistance performance (26 mOhm versus 40 mOhm at 2A, 4.5V), resulting in lower power dissipation (500 mW versus 1.5W). These improvements are beneficial for thermal management and efficiency in power switching applications. The substitute part exhibits slightly higher gate charge (7.5 nC versus 5.6 nC) and input capacitance (1010 pF versus 510 pF), which may require minor gate drive circuit adjustments in high-frequency switching applications but do not preclude direct substitution.

Packaging and Mechanical Compatibility:

Both parts utilize identical 9-UFBGA, DSBGA surface mount packaging, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can CSD25202W15 be used as a direct replacement for CSD25201W15 without PCB modifications?

A: Yes. Both parts share identical package geometry (9-UFBGA, DSBGA) and pinout. No PCB layout changes are required for mechanical and electrical compatibility.

Q: What is the primary reason for substituting CSD25201W15?

A: The CSD25201W15 is classified as obsolete. The CSD25202W15 is the active equivalent from Texas Instruments, ensuring long-term supply availability and production support.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, MSL Level 1 rating, and REACH Unaffected status. No additional regulatory qualification is required.

Q: How do the electrical performance differences affect circuit design?

A: The CSD25202W15 offers improved on-resistance (26 mOhm versus 40 mOhm), reducing power dissipation. Higher gate charge and input capacitance may require gate drive circuit evaluation in applications operating above 1 MHz switching frequency, but do not prevent substitution.

Q: Are both parts rated for the same voltage and current specifications?

A: Yes. Both parts are rated for 20V Vdss and 4A continuous drain current at 25°C, with identical -55°C to 150°C operating temperature range.

Q: What packaging format is available for CSD25202W15?

A: CSD25202W15 is supplied in Tape & Reel (TR) packaging, standard for production volume applications.
