TMUX1309PWR Equivalent & Substitute Parts

Part Overview

The TMUX1309PWR is an active, production-status interface integrated circuit manufactured by Texas Instruments. It functions as a 2-circuit SP4T (single-pole, 4-throw) analog switch with 4:1 multiplexer/demultiplexer capability. The device is packaged in a 16-TSSOP surface-mount configuration and operates across a single supply voltage range of 1.62V to 5.5V.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional specifications are maintained across alternative packaging formats or qualified variants. The availability of substitute parts ensures design flexibility, supply chain continuity, and compliance with specific application requirements such as automotive qualification.

Engineering Selection Recommendations

TMUX1309PWR Selection: The TMUX1309PWR is appropriate for general-purpose applications requiring a 2-circuit SP4T analog switch with 4:1 multiplexing capability. The device maintains active product status and full RoHS3 compliance. It is supplied in Tape & Reel packaging format, suitable for high-volume manufacturing environments. This variant is recommended for standard industrial and consumer applications where automotive qualification is not required.

TMUX1309QPWRQ1 Selection: The TMUX1309QPWRQ1 is the automotive-qualified equivalent, bearing AEC-Q100 certification. It maintains identical electrical and mechanical specifications to the TMUX1309PWR while offering qualification for automotive-grade applications. This variant is supplied in Cut Tape and Digi-Reel® packaging formats. Selection of this part is required for automotive applications, safety-critical systems, or designs subject to automotive supply chain requirements.

Both parts are manufactured by Texas Instruments, maintain active product status, and are ROHS3 compliant. The choice between them is determined by application requirements and packaging format preferences rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the TMUX1309QPWRQ1 be used as a direct replacement for the TMUX1309PWR in non-automotive applications?

A: Yes. The TMUX1309QPWRQ1 maintains identical electrical specifications, on-state resistance, switching characteristics, bandwidth, and operating temperature range. The automotive qualification and AEC-Q100 certification do not restrict use in standard applications. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Q: What is the significance of the AEC-Q100 qualification on the TMUX1309QPWRQ1?

A: AEC-Q100 qualification indicates the device has undergone automotive-grade reliability testing and meets automotive industry standards. This certification is required for components used in automotive applications but does not alter the electrical performance or functional characteristics of the device.

Q: Are there differences in packaging that affect circuit board assembly?

A: Both parts use the 16-TSSOP package with identical dimensions (0.173", 4.40mm Width). The difference lies in supply format: TMUX1309PWR is supplied in Tape & Reel (TR) format, while TMUX1309QPWRQ1 is supplied in Cut Tape (CT) and Digi-Reel® formats. All formats are compatible with standard surface-mount assembly equipment. Selection depends on manufacturing volume and handling preferences.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TMUX1309PWR and TMUX1309QPWRQ1 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the channel-to-channel matching specification, and why is it important?

A: Channel-to-Channel Matching (ΔRon) of 7 Ohm maximum indicates the variation in on-state resistance between the four switch channels. Both parts maintain this specification, ensuring consistent signal attenuation across all multiplexed channels. This parameter is critical for applications requiring uniform gain or impedance matching.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not require automotive qualification. The electrical and mechanical specifications are identical. If the design is currently using TMUX1309PWR and automotive qualification becomes necessary, substitution with TMUX1309QPWRQ1 requires only verification of packaging format compatibility with the assembly process.

Q: What is the leakage current specification, and how does it affect circuit design?

A: The leakage current (IS(off)) is specified as 1nA typical in the off state. This low leakage ensures minimal signal degradation when channels are inactive. Both parts maintain this specification, making them suitable for precision analog switching applications where off-channel isolation is critical.
