TSH84IPT Equivalent & Substitute Parts

Part Overview

The TSH84IPT is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring four independent circuits in a 14-TSSOP surface-mount package. This device is classified as obsolete, indicating discontinuation from the manufacturer. The rail-to-rail output configuration and automotive-grade qualification (AEC-Q100) make it suitable for automotive and industrial applications requiring four independent amplification stages. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH84IPT is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Compatibility Parameters:

• Four independent amplifier circuits in single package
• Rail-to-rail output configuration
• 14-TSSOP surface-mount package (0.173", 4.40mm Width)
• Supply voltage range compatibility (minimum 4.5 V to maximum 12 V overlap)
• Operating temperature range (-40°C minimum)
• RoHS3 compliance
• MSL 1 rating

Substitution Logic: All identified substitute parts maintain identical package geometry, circuit count, and output type. Substitute parts are grouped into two categories based on supply voltage range compatibility:

Category A - Full Supply Range Compatibility (4.5 V to 12 V): Parts with minimum supply voltage of 4.5 V or lower and maximum supply voltage of 12 V or higher maintain complete compatibility with the TSH84IPT supply specifications.

Category B - Extended Supply Range (2.7 V to 12 V): Parts with minimum supply voltage of 2.7 V provide extended lower-voltage capability beyond the TSH84IPT specification, while maintaining the 12 V maximum. These parts are substitutable in applications requiring the TSH84IPT's 4.5 V minimum specification.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q100 Requirement:

The TL974QPWRQ1 (Texas Instruments) is the direct functional equivalent for applications requiring automotive-grade qualification and AEC-Q100 compliance. This part maintains identical package geometry, circuit configuration, and supply voltage range compatibility with the TSH84IPT while offering active product status and extended operating temperature range (-40°C to 125°C). The TL974QPWRQ1 is available in Tape & Reel packaging with 57,201 units in stock.

For General-Purpose Applications without Automotive Qualification:

The TL974IPWR (Texas Instruments) and TL974IPW (Texas Instruments) provide equivalent functionality with active product status. Both variants feature identical electrical characteristics and package specifications. The TL974IPWR in Cut Tape & Digi-Reel packaging offers 21,966 units in stock, while the TL974IPW in Tube packaging provides 2,860 units. These parts support extended operating temperature range (-40°C to 125°C).

For Low-Power Applications:

The OP481GRUZ-REEL (Analog Devices Inc.) is suitable for applications prioritizing minimal supply current consumption. This part operates at 3.3 µA total supply current across four channels, compared to the TSH84IPT's 9.8 mA specification. The OP481GRUZ-REEL maintains identical package and circuit configuration with 2,609 units available in Tape & Reel packaging.

For Extended Lower-Voltage Operation:

The OP462HRUZ-REEL (Analog Devices Inc.) supports operation at 2.7 V minimum supply voltage, extending the lower voltage capability beyond the TSH84IPT's 4.5 V minimum. This part is available in Cut Tape & Digi-Reel packaging with 1,420 units in stock and supports extended operating temperature range (-40°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can the TL974QPWRQ1 directly replace the TSH84IPT in automotive applications?

A: Yes. The TL974QPWRQ1 maintains identical package geometry (14-TSSOP), circuit count (4 independent amplifiers), output type (rail-to-rail), and supply voltage range (2.7 V to 12 V, which encompasses the TSH84IPT's 4.5 V to 12 V requirement). Both parts carry automotive-grade qualification and AEC-Q100 certification. The TL974QPWRQ1 supports extended operating temperature range (-40°C to 125°C) compared to the TSH84IPT (-40°C to 85°C).

Q: What is the primary difference between the TL974IPWR and TL974QPWRQ1?

A: The TL974QPWRQ1 carries automotive-grade qualification and AEC-Q100 certification, while the TL974IPWR does not. Both parts are electrically identical and use the same 14-TSSOP package. Selection depends on whether automotive qualification is required for the application.

Q: Are all substitute parts compatible with the TSH84IPT's 4.5 V minimum supply voltage?

A: All identified substitute parts support operation at 4.5 V or lower minimum supply voltage (ranging from 2.7 V to 4.5 V), ensuring compatibility with applications designed for the TSH84IPT's 4.5 V to 12 V supply range.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in three packaging formats: Cut Tape & Digi-Reel (TL974IPWR, OP462HRUZ-REEL), Tape & Reel (TL974QPWRQ1, OP481GRUZ-REEL), and Tube (TL974IPW). Selection depends on production volume and assembly equipment compatibility.

Q: Does the OP481GRUZ-REEL maintain the same operating temperature range as the TSH84IPT?

A: Yes. The OP481GRUZ-REEL operates across the identical temperature range (-40°C to 85°C) as the TSH84IPT. Other substitute parts (OP462HRUZ-REEL, TL974 variants) support extended temperature range (-40°C to 125°C).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the TSH84IPT specifications.

Q: Which substitute part offers the lowest supply current consumption?

A: The OP481GRUZ-REEL operates at 3.3 µA total supply current across four channels, significantly lower than the TSH84IPT's 9.8 mA specification. This part is suitable for battery-powered or ultra-low-power applications.
