Frequently Asked Questions (FAQ)

Q: Can the TS3A5017RGYR be used as a direct replacement for the TS3A5017RGYRG4?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The TS3A5017RGYR differs only in product status (Active vs. Discontinued) and packaging format (Cut Tape & Digi-Reel availability). No circuit modifications are required for substitution.

Q: What are the critical parameters that define substitution compatibility?

A: Substitution is determined by equivalence in switch circuit configuration (SP4T, 2 circuits, 4:1 multiplexer), on-state resistance (12Ω), supply voltage range (2.3V ~ 3.6V), switching speed (9.5ns/4.6ns), bandwidth (165MHz), and package type (16-VQFN with exposed pad). All these parameters are identical between the main part and substitute.

Q: Are there any differences in handling or storage requirements?

A: No. Both parts carry the same Moisture Sensitivity Level (MSL 2, 1 Year), requiring identical handling, storage, and reflow procedures. Standard ESD precautions and dry-pack storage conditions apply to both parts.

Q: Does the packaging format difference affect circuit performance?

A: No. The TS3A5017RGYR is available in Cut Tape & Digi-Reel packaging format, which is a supply chain variation only. The actual component, pinout, and electrical performance remain unchanged. Packaging format does not affect circuit functionality or performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TS3A5017RGYRG4 and TS3A5017RGYR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
