TSV854AIYPT Equivalent & Substitute Parts
Part Overview
The TSV854AIYPT is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a 4-circuit rail-to-rail device in a 14-TSSOP surface-mount package. This IC is designed for low-voltage analog signal processing applications requiring multiple amplification stages. The part is active in production with automotive-grade qualification (AEC-Q100) and operates across an extended temperature range of -40°C to 125°C.
Equivalent and substitute parts are identified based on matching functional specifications, package geometry, electrical performance parameters, and compliance certifications. Alternative components serve applications where the TSV854AIYPT is unavailable, end-of-life, or where design flexibility permits component substitution within defined electrical and mechanical constraints.

Engineering Selection Recommendations
Automotive-Qualified Alternatives:
The LMV324Q1MTX/NOPB (Texas Instruments) is the primary automotive-grade substitute for the TSV854AIYPT. Both parts carry AEC-Q100 qualification and operate across the full -40°C to 125°C temperature range. The LMV324Q1MTX/NOPB is supplied in Tape & Reel packaging, matching the original part's delivery format. This part exhibits higher output current capability (160 mA per channel versus 70 mA) and lower supply current consumption (410 µA total versus 130 µA), making it suitable for applications requiring increased output drive or reduced power dissipation.
The LMV324Q3MT/NOPB (Texas Instruments) provides automotive qualification with identical electrical specifications to the LMV324Q1MTX/NOPB but operates to 85°C maximum. This part is supplied in Tube packaging and is appropriate for applications with reduced upper temperature requirements.
General-Purpose Alternatives (Non-Automotive):
The AD8544ARUZ and AD8544ARUZ-REEL (Analog Devices Inc.) maintain the full -40°C to 125°C operating range with superior input bias current performance (4 pA versus 27 nA). These parts differ in packaging format: AD8544ARUZ is supplied in Tube, while AD8544ARUZ-REEL is supplied in Cut Tape & Digi-Reel format. Both exhibit reduced output current capability (30 mA per channel) and lower supply current (45 µA total).
The LMV324IPWR, LMV324MT/NOPB, and LMV324MTX/NOPB (Texas Instruments) provide -40°C to 125°C operation with enhanced output current (40 to 160 mA per channel). These parts differ in packaging and output current specifications. The LMV324MT/NOPB and LMV324MTX/NOPB offer the highest output current (160 mA per channel).
Limited-Temperature Alternatives:
The APX324TSG-13 (Diodes Incorporated) and Rohm Semiconductor parts (BD12734FVJ-E2, LMR934FVJ-E2) operate to 85°C maximum and are suitable only for applications with reduced upper temperature requirements. The APX324TSG-13 provides higher output current (90 mA per channel) but elevated supply current (340 µA total). The Rohm parts exhibit lower slew rates and reduced output current capability.
Compliance Status:
All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the TSV854AIYPT. Parts carrying automotive qualification (LMV324Q1MTX/NOPB, LMV324Q3MT/NOPB) are restricted to applications requiring AEC-Q100 certification.
Frequently Asked Questions (FAQ)
Q: Can the AD8544ARUZ directly replace the TSV854AIYPT in automotive applications?
A: The AD8544ARUZ is not automotive-qualified and does not carry AEC-Q100 certification. It is suitable only for general-purpose applications. For automotive designs, use LMV324Q1MTX/NOPB or LMV324Q3MT/NOPB.
Q: What is the primary difference between LMV324Q1MTX/NOPB and LMV324Q3MT/NOPB?
A: Both parts are automotive-qualified with identical electrical specifications. The LMV324Q1MTX/NOPB operates to 125°C and is supplied in Tape & Reel packaging. The LMV324Q3MT/NOPB operates to 85°C maximum and is supplied in Tube packaging. Select based on temperature requirements and packaging format.
Q: Are all substitute parts pin-compatible with the TSV854AIYPT?
A: Yes. All substitute parts use the 14-TSSOP package with identical pin assignments and footprint dimensions (0.173", 4.40mm width). PCB layout modifications are not required for package compatibility.
Q: Which substitute part has the lowest power consumption?
A: The AD8544ARUZ and AD8544ARUZ-REEL exhibit the lowest supply current at 45 µA total (across 4 channels). The TSV854AIYPT consumes 130 µA, while most Texas Instruments LMV324 variants consume 410 µA.
Q: Can I use APX324TSG-13 in a design requiring -40°C to 125°C operation?
A: No. The APX324TSG-13 operates only to 85°C maximum. It is not suitable for applications requiring the full -40°C to 125°C temperature range. Use LMV324Q1MTX/NOPB, LMV324IPWR, or AD8544ARUZ variants instead.
Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?
A: Tape & Reel (TR) packaging supplies components on continuous tape suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging supplies components on cut tape segments, typically for lower-volume or mixed-component orders. Both formats are compatible with standard pick-and-place equipment.
Q: Does the LMV324MT/NOPB offer advantages over LMV324MTX/NOPB?
A: Both parts have identical electrical specifications and operate to -40°C to 125°C. The primary difference is packaging: LMV324MT/NOPB is supplied in Tube format, while LMV324MTX/NOPB is supplied in Cut Tape & Digi-Reel format. Select based on procurement and assembly requirements.
Q: Is the TSV854AIYPT still in active production?
A: Yes. The TSV854AIYPT is listed as active product status with 2263 pieces in stock. Equivalent and substitute parts are identified to provide design flexibility and supply chain alternatives.
Q: Which substitute part most closely matches the TSV854AIYPT's output current specification?
A: The APX324TSG-13 provides 90 mA per channel output current, closest to the TSV854AIYPT's 70 mA specification. However, the APX324TSG-13 operates only to 85°C. For full -40°C to 125°C operation with comparable output current, the LMV324MT/NOPB and LMV324MTX/NOPB provide 160 mA per channel.
Q: Can I substitute the TSV854AIYPT with a part having different slew rate or gain-bandwidth product?
A: Substitution is permissible only if the application specifications allow for the different slew rate and gain-bandwidth product values. Verify that the substitute part's dynamic performance meets circuit bandwidth and settling time requirements. Consult application schematics and signal processing specifications before substitution.
