Engineering Selection Recommendations

The TS3A5017PWR is the direct substitute for the TS3A5017PW. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the TS3A5017PW is Last Time Buy (discontinued), while the TS3A5017PWR maintains Active status with current production availability.

From a compliance perspective, both parts satisfy ROHS3 requirements and carry MSL Level 1 ratings, indicating equivalent environmental handling and regulatory standing. The TS3A5017PWR is recommended for new designs and ongoing production requirements due to its active manufacturing status and superior inventory availability (35,400 units in stock versus 1,695 units for the TS3A5017PW).

The packaging difference between Tube (TS3A5017PW) and Cut Tape & Digi-Reel (TS3A5017PWR) reflects distribution format only and does not affect component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Can the TS3A5017PWR be used as a direct replacement for the TS3A5017PW in existing designs?

A: Yes. The TS3A5017PWR is electrically and mechanically identical to the TS3A5017PW. All electrical parameters, switching characteristics, supply voltage requirements, and package footprints are equivalent. No circuit modifications are required.

Q: What is the difference between the Tube and Cut Tape & Digi-Reel packaging formats?

A: Packaging format affects component delivery and handling only. Tube packaging is used for smaller quantities, while Cut Tape & Digi-Reel format is used for higher-volume production runs. Both formats contain identical components with identical performance specifications.

Q: Why is the TS3A5017PW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The TS3A5017PWR has replaced it in the active product line. Existing inventory of the TS3A5017PW remains available, but new designs should transition to the TS3A5017PWR to ensure long-term supply continuity.

Q: Are there any performance differences between these two part numbers?

A: No. Both components share identical on-state resistance (12Ohm), switching times (9.5ns Ton, 4.6ns Toff), bandwidth (165MHz), and all other electrical specifications. Performance in signal routing and multiplexing applications is equivalent.

Q: What are the key parameters that determine substitution eligibility for SP4T analog switches?

A: Substitution requires matching of switch circuit topology (SP4T), multiplexer configuration (4:1), on-state resistance (12Ohm), supply voltage range (2.3V ~ 3.6V), switching times, bandwidth, and package footprint (16-TSSOP). Any deviation in these parameters disqualifies a component as a direct substitute.
