TS5A3167DBVR Equivalent & Substitute Parts

Part Overview

The TS5A3167DBVR is a single-circuit SPST-NC (Normally Closed) analog switch manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This component operates across a supply voltage range of 1.65V to 5.5V with a maximum on-state resistance of 900mOhm and is designed for high-speed switching applications with a -3dB bandwidth of 150MHz. The part is currently in active production status with 17,400 units in stock.

Substitute parts are necessary when the original component becomes unavailable, when design requirements demand improved electrical performance characteristics, or when alternative manufacturers' components offer superior specifications within the same functional category and package compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TS5A3167DBVR is determined by the following mandatory criteria:

Switch circuit type must be SPST - NC (Normally Closed)
Multiplexer/Demultiplexer circuit configuration must be 1:1
Number of circuits must be 1
Package / Case must be SC-74A or SOT-753 compatible
Supply voltage range must overlap with or exceed 1.65V ~ 5.5V
Operating temperature range must cover -40°C ~ 85°C minimum
RoHS3 compliance required
Surface mount mounting type required

The four qualified substitute parts meet all mandatory criteria. Variations in on-state resistance, switch time, bandwidth, and leakage current are acceptable within the functional category, as these parameters do not prevent electrical or mechanical interchangeability in the specified application context.

Engineering Selection Recommendations

All four substitute parts maintain ROHS3 compliance and are surface mount components in SC-74A/SOT-753 packages, ensuring mechanical and electrical interchangeability with the TS5A3167DBVR.

74LVC1G384GV,125 (Nexperia USA Inc.) is in active production status with the highest inventory availability (28,334 units). This part offers superior on-state resistance (10Ohm versus 900mOhm) and faster switching times, with extended operating temperature range to 125°C. MSL rating of 1 provides unlimited moisture sensitivity protection.

PI5A3167CTAEX (Diodes Incorporated) carries a Last Time Buy status, indicating discontinued production. While it offers the lowest on-state resistance (1.2Ohm) and fastest switching times, procurement should be limited to applications where long-term supply is not required. MSL rating of 1 is maintained.

MAX4569EUK+T (Analog Devices Inc./Maxim Integrated) is in active production with extended supply voltage range (1.8V ~ 12V), accommodating higher voltage applications. On-state resistance of 70Ohm and slower switching times (150ns/80ns) may be limiting factors for high-frequency applications. MSL rating of 1 is maintained.

ISL43113IHZ-T (Renesas Electronics Corporation) is in active production and supports dual supply voltage operation (±1.5V ~ 6V), offering design flexibility for bipolar supply systems. However, MSL rating of 3 (168 hours) requires controlled moisture exposure during storage and handling. Lowest leakage current (1nA) is advantageous for low-power applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the TS5A3167DBVR?

A: All four substitute parts are mechanically and electrically compatible within the SC-74A/SOT-753 package footprint and maintain the same SPST-NC switch circuit topology. However, differences in on-state resistance, switching speed, and supply voltage ranges may affect circuit performance. Verify that the substitute part's electrical characteristics meet your specific application requirements before implementation.

Q: What is the primary difference between the TS5A3167DBVR and the 74LVC1G384GV,125?

A: The 74LVC1G384GV,125 offers significantly lower on-state resistance (10Ohm versus 900mOhm), faster switching times (4.2ns/5ns versus 7.5ns/11ns), and higher bandwidth (500MHz versus 150MHz). The 74LVC1G384GV,125 also supports an extended operating temperature range to 125°C. These improvements make it suitable for applications requiring lower signal distortion and faster response times.

Q: Why is the PI5A3167CTAEX marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part. While current inventory is available (6,100 units), future procurement will not be possible. This part should only be selected if immediate availability is critical and long-term supply is not required.

Q: What does MSL rating mean, and why does ISL43113IHZ-T have a different rating?

A: MSL (Moisture Sensitivity Level) rating indicates the component's sensitivity to moisture during storage and handling. The TS5A3167DBVR, 74LVC1G384GV,125, PI5A3167CTAEX, and MAX4569EUK+T all have MSL 1 (Unlimited), meaning they can be stored indefinitely without moisture control. The ISL43113IHZ-T has MSL 3 (168 hours), requiring that the component be used within 168 hours of opening the moisture barrier bag. This affects supply chain handling and storage procedures.

Q: Can I use ISL43113IHZ-T in a single supply voltage application?

A: No. The ISL43113IHZ-T is specified only for dual supply voltage operation (±1.5V ~ 6V) and does not support single supply voltage configurations. The TS5A3167DBVR, 74LVC1G384GV,125, PI5A3167CTAEX, and MAX4569EUK+T all support single supply voltage operation and are suitable for single-supply applications.

Q: Which substitute part has the lowest on-state resistance?

A: The PI5A3167CTAEX has the lowest on-state resistance at 1.2Ohm maximum, compared to 900mOhm for the TS5A3167DBVR. Lower on-state resistance reduces signal attenuation and power dissipation in switching applications. However, the PI5A3167CTAEX is in Last Time Buy status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts (74LVC1G384GV,125, PI5A3167CTAEX, MAX4569EUK+T, and ISL43113IHZ-T) maintain ROHS3 compliance, meeting environmental and regulatory requirements equivalent to the TS5A3167DBVR.
