Engineering Selection Recommendations

The TPA0102PWPR is a direct functional equivalent to the TPA0102PWPRG4 for all electrical, thermal, and mechanical specifications. Selection between these parts should be based on the following criteria:

For Discontinued Part Replacement: The TPA0102PWPR is the appropriate selection when the TPA0102PWPRG4 is no longer available. Both parts share identical electrical performance, package geometry, and compliance certifications (ROHS3, MSL 2).

Packaging Considerations: The TPA0102PWPR is supplied in Tape & Reel (TR) format, which is standard for production volume applications. If individual unit packaging is required, alternative sourcing channels or packaging services may be necessary.

Product Status: The TPA0102PWPR maintains Active product status with Texas Instruments, ensuring long-term availability and continued technical support. The TPA0102PWPRG4 is discontinued, making the TPA0102PWPR the recommended path for new designs and ongoing production.

Compliance & Regulatory: Both parts maintain identical RoHS3 compliance and REACH unaffected status, supporting equivalent regulatory requirements across applications.
