Engineering Selection Recommendations

Primary Recommendation: TS5A3167DBVR

The TS5A3167DBVR is the direct functional equivalent of the TS5A3167DBVRG4, manufactured by Texas Instruments with identical electrical specifications. This part maintains the same on-state resistance of 900mOhm, supply voltage range of 1.65V to 5.5V, and switching characteristics. The TS5A3167DBVR is currently in Active product status with 17,400 units in stock, providing immediate availability and supply chain continuity. Both parts carry ROHS3 compliance and REACH Unaffected status. The only difference is packaging format (Tape & Reel versus the original specification), which does not affect functional performance.

Secondary Recommendations:

74LVC1G384GV,125 (Nexperia USA Inc.) offers superior performance characteristics with significantly lower on-state resistance of 10Ohm, faster switching times (4.2ns, 5ns), and extended bandwidth of 500MHz. This part is Active with 28,334 units in stock. The extended operating temperature range to 125°C provides additional thermal margin. Leakage current is higher at 500nA, which may be relevant in low-power applications.

PI5A3167CTAEX (Diodes Incorporated) provides the lowest on-state resistance at 1.2Ohm with fast switching times of 6ns and 7.5ns, and the lowest channel capacitance at 4.6pF. This part is designated Last Time Buy, indicating limited future availability. Charge injection is elevated at 35pC compared to the original specification.

MAX4569EUK+T (Analog Devices Inc./Maxim Integrated) operates across an extended supply voltage range of 1.8V to 12V with on-state resistance of 70Ohm. This part is Active with 2,700 units in stock and offers the lowest leakage current at 500pA, suitable for ultra-low-power applications.

ISL43113IHZ-T (Renesas Electronics Corporation) supports dual supply operation (±1.5V to 6V) with on-state resistance of 20Ohm and exceptionally low leakage current of 1nA. This part is Active but has limited inventory at 1,021 units. Moisture sensitivity level is MSL 3, requiring controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use TS5A3167DBVR as a direct replacement for TS5A3167DBVRG4?

A: Yes. The TS5A3167DBVR is functionally identical to the TS5A3167DBVRG4 with matching electrical specifications, including on-state resistance, supply voltage range, switching characteristics, and operating temperature. The difference is packaging format (Tape & Reel). Both parts are ROHS3 compliant and REACH Unaffected.

Q: What is the primary difference between the substitute parts?

A: The substitute parts vary primarily in on-state resistance, switching speed, and supply voltage compatibility. The TS5A3167DBVR maintains identical specifications to the original part. The 74LVC1G384GV,125 offers lower resistance and faster switching. The PI5A3167CTAEX provides the lowest resistance but is Last Time Buy. The MAX4569EUK+T supports higher supply voltages. The ISL43113IHZ-T supports dual supply operation.

Q: Are all substitute parts available in the same package?

A: All substitute parts use SC-74A or SOT-753 package designations and are surface mount components. However, specific supplier device packages vary: SOT-23-5 for most parts, SC-74A for the 74LVC1G384GV,125, and 5-SOT for the ISL43113IHZ-T. Physical pin compatibility should be confirmed with detailed package drawings.

Q: Which substitute part has the best availability?

A: The 74LVC1G384GV,125 has the highest inventory at 28,334 units in stock. The TS5A3167DBVR has 17,400 units available. The PI5A3167CTAEX is designated Last Time Buy with 6,100 units, indicating limited future availability.

Q: Can I use these parts interchangeably in all applications?

A: Substitution depends on application requirements. All parts maintain SPST-NC 1:1 switch functionality and surface mount packaging. However, on-state resistance variations (ranging from 1.2Ohm to 900mOhm) affect signal integrity and power dissipation. Supply voltage requirements differ: most support 1.65V to 5.5V, but MAX4569EUK+T extends to 12V and ISL43113IHZ-T supports dual supply. Switching speed and leakage current specifications should be evaluated against application performance requirements.

Q: What is the significance of the Last Time Buy status for PI5A3167CTAEX?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part. While 6,100 units are currently in stock, future availability is not guaranteed. This part should be selected only if its specific performance characteristics (lowest on-state resistance and capacitance) are critical to the application.

Q: Does moisture sensitivity level affect part selection?

A: Most substitute parts carry MSL 1 (Unlimited), allowing standard storage and handling. The ISL43113IHZ-T carries MSL 3 (168 Hours), requiring controlled humidity storage and limiting the time the part can be exposed to ambient conditions before soldering. This affects supply chain logistics and manufacturing processes.
