TSV358AIYPT Equivalent & Substitute Parts
Part Overview
The TSV358AIYPT is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in an 8-TSSOP surface-mount package. This device is classified as a rail-to-rail output amplifier with automotive-grade qualification (AEC-Q100) and is currently in active production status. The TSV358AIYPT is designed for applications requiring low-power, general-purpose amplification across industrial and automotive environments.
Equivalent and substitute parts are identified based on matching functional characteristics, electrical performance parameters, package compatibility, and compliance certifications. Substitution becomes necessary when the primary part experiences supply constraints, when alternative packaging formats are required for manufacturing processes, or when design flexibility demands components with comparable electrical specifications.

Engineering Selection Recommendations
Direct Package Equivalents (8-TSSOP Format)
The NCS20082DTBR2G (onsemi) and AD8532ARUZ-REEL (Analog Devices) are direct 8-TSSOP package equivalents to the TSV358AIYPT. Both devices maintain identical physical footprints and pin configurations, enabling direct board-level substitution without layout modifications. All three parts are ROHS3 compliant and REACH unaffected, meeting identical environmental compliance requirements.
The NCS20082DTBR2G operates across the full -40°C to 125°C temperature range matching the TSV358AIYPT, while the AD8532ARUZ-REEL operates to 85°C maximum. The NCS20082DTBR2G features lower supply current consumption (48 µA per channel) compared to the TSV358AIYPT (500 µA), making it suitable for power-constrained applications. The AD8532ARUZ-REEL provides higher output current capability (250 mA per channel) and faster slew rate (5 V/µs) for applications requiring greater drive capability.
Alternative Package Formats
The OPA2313IDGKR (Texas Instruments) in 8-VSSOP package and MCP6L02T-E/MS (Microchip) in 8-MSOP package provide electrical equivalence with different physical form factors. These alternatives are suitable when PCB layout constraints or manufacturing processes require alternative package geometries. Both maintain full -40°C to 125°C operating temperature range and ROHS3 compliance.
The OPA2313IDGKR offers extremely low input bias current (0.2 pA) and operates across 1.8 V to 5.5 V supply range. The MCP6L02T-E/MS provides extended supply voltage range (1.8 V to 6 V) and operates to 125°C, with very low input bias current (2 pA).
Automotive and Extended Temperature Applications
For applications requiring automotive-grade qualification, the TSV358AIYPT maintains AEC-Q100 certification. Among the substitute parts listed, none explicitly state automotive qualification. Applications requiring automotive-grade components should prioritize the TSV358AIYPT or verify automotive qualification status with manufacturers for alternative selections.
Supply Voltage Compatibility
All listed substitute parts operate within overlapping supply voltage ranges. The TSV358AIYPT operates from 2.5 V to 6 V. Substitute parts with lower minimum supply voltage (1.6 V to 1.8 V) provide additional flexibility for low-voltage applications, while those with maximum supply voltage of 5.5 V require design verification for 6 V operation.
Moisture Sensitivity Considerations
The TSV358AIYPT and most substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The OPA2313IDGK and OPA2313IDGKR carry MSL 2 (1 Year) rating, requiring standard moisture control during storage and handling.
Frequently Asked Questions (FAQ)
Q: Can the AD8532ARUZ-REEL directly replace the TSV358AIYPT on existing PCBs?
A: Yes. Both devices use identical 8-TSSOP package with 0.173" width and 4.40mm body dimensions. Pin configurations are compatible for dual general-purpose amplifier applications. No PCB layout modifications are required. However, verify that the maximum operating temperature of 85°C for the AD8532ARUZ-REEL meets application requirements, as the TSV358AIYPT operates to 125°C.
Q: What are the key differences between 8-TSSOP, 8-MSOP, 8-VSSOP, and 8-uMAX/uSOP packages?
A: These are all 8-pin surface-mount packages with different physical dimensions and body widths. The 8-TSSOP (0.173" width) and 8-MSOP (0.118" width) are the most common. The 8-VSSOP and 8-uMAX/uSOP are alternative compact formats. All maintain identical pin pitch and electrical functionality. Package selection depends on PCB layout constraints and manufacturing equipment capabilities. Verify footprint compatibility with your specific PCB design before substitution.
Q: Is the NCS20082DTBR2G suitable for automotive applications?
A: The NCS20082DTBR2G operates across the full -40°C to 125°C temperature range required for automotive environments. However, the provided specifications do not indicate AEC-Q100 qualification. The TSV358AIYPT explicitly carries AEC-Q100 automotive qualification. For applications requiring automotive-grade certification, contact the manufacturer to verify qualification status before substitution.
Q: How do slew rate differences affect circuit performance?
A: Slew rate determines how quickly an amplifier output can change voltage. The TSV358AIYPT has 0.6 V/µs slew rate. Substitute parts range from 0.4 V/µs to 5 V/µs. Lower slew rates limit high-frequency signal handling and may introduce distortion in fast-switching applications. Higher slew rates provide better performance for high-frequency signals but may increase noise in sensitive applications. Select based on your specific signal bandwidth requirements.
Q: What is the significance of input bias current differences?
A: Input bias current affects circuit accuracy and noise performance. The TSV358AIYPT has 70 nA input bias current. Substitute parts range from 0.2 pA to 70 nA. Lower input bias current reduces errors in high-impedance circuits and precision measurement applications. For general-purpose applications with moderate impedance levels, differences in this range are typically not critical. For precision instrumentation, select parts with lower input bias current (OPA2313 series at 0.2 pA).
Q: Can I use the MAX4246AUA+ in place of TSV358AIYPT for high-current output applications?
A: No. The MAX4246AUA+ provides only 30 mA output current per channel, compared to 80 mA for the TSV358AIYPT. For applications requiring 80 mA output current, the AD8532ARUZ series (250 mA per channel) or AZV832MMTR-G1 (185 mA per channel) are more suitable alternatives.
Q: Are all listed substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance certification and REACH unaffected status, matching the environmental compliance profile of the TSV358AIYPT.
Q: What supply current differences should I consider?
A: The TSV358AIYPT draws 500 µA total supply current. Substitute parts range from 48 µA to 750 µA. Lower supply current (NCS20082DTBR2G at 48 µA per channel) reduces power consumption and heat generation, beneficial for battery-powered or thermally constrained applications. Higher supply current (AD8532ARUZ at 750 µA per channel) may provide improved performance characteristics. Select based on power budget and thermal constraints.
Q: What is the difference between Cut Tape (CT) & Digi-Reel and Tape & Reel (TR) packaging?
A: Cut Tape (CT) & Digi-Reel packaging provides components on tape that can be cut to length for smaller orders or mixed component shipments. Tape & Reel (TR) packaging provides full reels for high-volume automated assembly. Both formats are suitable for surface-mount assembly. Selection depends on order quantity and assembly equipment compatibility. The TSV358AIYPT is available in Cut Tape (CT) & Digi-Reel format.
