Substitute Part Grouping Explanation

Substitution eligibility for the TS3A5017D is determined by strict equivalence across the following critical parameters:

Switch Circuit Architecture: Must be SP4T configuration with 2 independent circuits
Multiplexer Ratio: Must be 4:1 multiplexer/demultiplexer
On-State Resistance: Must be 12Ohm maximum
Channel Matching: Must maintain 1Ohm channel-to-channel matching specification
Supply Voltage Compatibility: Must support 2.3V ~ 3.6V single supply operation
Switching Performance: Must meet or exceed 9.5ns turn-on and 4.6ns turn-off specifications
Bandwidth: Must support 165MHz -3dB bandwidth minimum
Package Compatibility: Must be 16-SOIC form factor with identical pinout
Compliance Requirements: Must maintain ROHS3 compliance and MSL 1 rating

The TS3A5017DR qualifies as a direct substitute based on identical electrical specifications and package configuration, with the primary distinction being packaging format and product status.

Engineering Selection Recommendations

The TS3A5017DR is the direct equivalent substitute for the TS3A5017D. Both components share identical electrical specifications, performance characteristics, and package configuration. The TS3A5017DR maintains Active product status, ensuring continued availability and supply chain support, whereas the TS3A5017D is designated Last Time Buy. Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The primary distinction is packaging format: the TS3A5017D is supplied in Tube packaging, while the TS3A5017DR is available in Cut Tape and Digi-Reel formats. Selection between these variants should be based on procurement requirements and assembly process compatibility rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the TS3A5017DR be used as a direct replacement for the TS3A5017D in existing designs?

A: Yes. The TS3A5017DR is electrically and mechanically identical to the TS3A5017D. Both components feature the same SP4T switch configuration, 12Ohm on-state resistance, 4:1 multiplexer ratio, and 16-SOIC package footprint. No design modifications are required for substitution.

Q: What is the difference between the TS3A5017D and TS3A5017DR?

A: The components are electrically equivalent. The TS3A5017D is supplied in Tube packaging and carries Last Time Buy status. The TS3A5017DR is supplied in Cut Tape and Digi-Reel formats and maintains Active product status. The TS3A5017DR is recommended for new designs and ongoing production due to its active availability.

Q: Are there any package compatibility concerns when switching from TS3A5017D to TS3A5017DR?

A: No package compatibility concerns exist. Both parts use the 16-SOIC form factor with identical pinout and footprint. The difference in packaging format (Tube versus Cut Tape/Digi-Reel) affects only the delivery and handling method, not the component itself or PCB assembly compatibility.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the TS3A5017D and TS3A5017DR are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH Unaffected and classified under ECCN EAR99. Compliance requirements are identical.

Q: What are the key electrical parameters that define substitution eligibility for this part?

A: Substitution eligibility is determined by: SP4T switch configuration, 2 independent circuits, 4:1 multiplexer ratio, 12Ohm maximum on-state resistance, 1Ohm channel-to-channel matching, 2.3V ~ 3.6V supply voltage support, 9.5ns/4.6ns switching times, 165MHz bandwidth, and 16-SOIC package compatibility. All parameters must be met for direct substitution.
