TS974ID Equivalent & Substitute Parts

Part Overview

The TS974ID is a general-purpose operational amplifier integrated circuit manufactured by STMicroelectronics, configured as a 4-circuit rail-to-rail amplifier in a 14-SOIC surface-mount package. The device is classified as obsolete, though 735 units remain in stock as new original inventory. The TS974ID is qualified to AEC-Q100 automotive standards and complies with ROHS3 and REACH regulations.

Due to the obsolete product status of the TS974ID, identification of equivalent and substitute parts is necessary for ongoing design support, production continuity, and long-term component availability. Active alternatives from multiple manufacturers provide functional equivalence while maintaining automotive-grade qualification and compliance certifications.

Engineering Selection Recommendations

Primary Recommendation: TS974IDT

The TS974IDT is the direct active equivalent of the TS974ID, manufactured by STMicroelectronics. This part maintains identical electrical specifications, package configuration, and automotive-grade AEC-Q100 qualification. The TS974IDT is available in Tape & Reel packaging with 3,042 units in stock. Selection of TS974IDT eliminates design re-qualification requirements and provides the highest level of form-fit-function compatibility. This part is recommended for applications where design continuity and minimal validation effort are priorities.

Secondary Recommendations: TL974ID and TL974IDR

The TL974ID and TL974IDR, manufactured by Texas Instruments, provide functional equivalence with active product status. Both parts maintain the same 4-circuit general-purpose amplifier configuration, 14-SOIC package, and automotive temperature range. The TL974ID is supplied in Tube packaging (2,192 units in stock), while TL974IDR is supplied in Cut Tape & Digi-Reel packaging (20,138 units in stock). These parts exhibit marginally higher slew rate (5 V/µs versus 4 V/µs) and slightly lower output current per channel (80 mA versus 100 mA). Selection of TL974ID or TL974IDR is appropriate for applications where Texas Instruments supply chain preference or packaging format is a determining factor.

Alternative Recommendations: OP462GSZ and OP462GSZ-REEL7

The OP462GSZ and OP462GSZ-REEL7, manufactured by Analog Devices Inc., provide enhanced performance characteristics including higher slew rate (13 V/µs), higher gain bandwidth product (15 MHz), and lower input offset voltage (25 µV). These parts maintain the 14-SOIC package and automotive temperature range. OP462GSZ is supplied in Tube packaging (18,572 units in stock), while OP462GSZ-REEL7 is supplied in Tape & Reel packaging (5,200 units in stock). Selection of OP462GSZ or OP462GSZ-REEL7 is appropriate for applications requiring enhanced dynamic performance, though output current per channel is reduced to 30 mA.

Conditional Recommendation: MCP6H94-E/SL and MCP6H94T-E/SL

The MCP6H94-E/SL and MCP6H94T-E/SL, manufactured by Microchip Technology, provide functional equivalence with enhanced slew rate (10 V/µs) and significantly lower input bias current (10 pA). MCP6H94-E/SL is supplied in Tube packaging (3,000,200 units in stock), while MCP6H94T-E/SL is supplied in Tape & Reel packaging (2,869 units in stock). The MCP6H94-E/SL maintains MSL 1 rating, while MCP6H94T-E/SL carries MSL 3 (168 Hours). The minimum supply voltage is 3.5 V, which exceeds the TS974ID minimum of 2.7 V. Selection of MCP6H94-E/SL or MCP6H94T-E/SL is appropriate for applications where lower input bias current is beneficial and supply voltage remains above 3.5 V.

Not Recommended: TLV2264AID and TLV2264AIDR

The TLV2264AID and TLV2264AIDR, manufactured by Texas Instruments, are CMOS amplifiers with significantly different performance characteristics. These parts exhibit substantially lower gain bandwidth product (710 kHz versus 12 MHz) and slew rate (0.55 V/µs versus 4 V/µs), making them unsuitable for applications requiring the TS974ID performance envelope. Additionally, the maximum supply voltage is limited to 8 V, below the TS974ID maximum of 10 V. These parts are not recommended as substitutes for the TS974ID.

Frequently Asked Questions (FAQ)

Q: Can TS974IDT be used as a direct replacement for TS974ID?

A: Yes. The TS974IDT is manufactured by STMicroelectronics and maintains identical electrical specifications, package configuration (14-SOIC), and automotive-grade AEC-Q100 qualification as the TS974ID. The primary difference is product status: TS974IDT is active with 3,042 units in stock, while TS974ID is obsolete. TS974IDT is the recommended direct replacement.

Q: What is the difference between TS974IDT and TL974IDR?

A: Both parts are 4-circuit general-purpose rail-to-rail amplifiers in 14-SOIC packages with identical operating temperature ranges (-40°C ~ 125°C). TS974IDT is manufactured by STMicroelectronics with 4 V/µs slew rate and 100 mA output current per channel. TL974IDR is manufactured by Texas Instruments with 5 V/µs slew rate and 80 mA output current per channel. TS974IDT is recommended for design continuity; TL974IDR is an alternative if Texas Instruments supply chain preference exists.

Q: Can OP462GSZ replace TS974ID in all applications?

A: OP462GSZ provides enhanced performance with 13 V/µs slew rate and 15 MHz gain bandwidth product, exceeding TS974ID specifications. However, output current per channel is reduced to 30 mA versus 100 mA in TS974ID. OP462GSZ is suitable for applications where higher slew rate and bandwidth are beneficial and output current requirements do not exceed 30 mA per channel.

Q: What is the significance of MSL rating in the MCP6H94T-E/SL?

A: MCP6H94T-E/SL carries MSL 3 (168 Hours) rating, indicating moisture sensitivity requiring controlled storage and handling conditions. TS974ID, TS974IDT, and most alternative parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. MSL 3 rating requires storage in dry conditions and limits shelf life after moisture exposure. For applications with stringent supply chain requirements, MSL 1 parts are preferred.

Q: Why is the minimum supply voltage different for MCP6H94-E/SL?

A: MCP6H94-E/SL specifies a minimum supply voltage of 3.5 V, compared to 2.7 V for TS974ID. This difference reflects the internal circuit design of the Microchip device. MCP6H94-E/SL is suitable only for applications where the supply voltage remains above 3.5 V. For applications requiring operation at 2.7 V minimum supply, TS974IDT, TL974ID, TL974IDR, or OP462GSZ are appropriate selections.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TS974IDT, MCP6H94-E/SL, MCP6H94T-E/SL, OP462GSZ, OP462GSZ-REEL7, TL974ID, TL974IDR, TLV2264AID, TLV2264AIDR) are ROHS3 compliant and REACH unaffected, matching the compliance status of TS974ID.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (standard packaging for individual units), Tape & Reel (TR) for automated assembly, and Cut Tape & Digi-Reel for mixed-volume applications. TS974IDT is available in Tape & Reel; TL974ID is available in Tube; TL974IDR is available in Cut Tape & Digi-Reel. Selection depends on production volume and assembly equipment compatibility.

Q: Is automotive qualification (AEC-Q100) maintained across all substitute parts?

A: TS974ID carries explicit AEC-Q100 automotive qualification. Substitute parts from STMicroelectronics (TS974IDT) and Texas Instruments (TL974ID, TL974IDR) maintain automotive-grade designation and operating temperature range (-40°C ~ 125°C). Microchip Technology (MCP6H94-E/SL, MCP6H94T-E/SL) and Analog Devices Inc. (OP462GSZ, OP462GSZ-REEL7) parts meet automotive temperature specifications but do not carry explicit AEC-Q100 qualification notation in the provided data. For applications requiring formal AEC-Q100 certification, TS974IDT is the recommended selection.
