TSV6291ICT Equivalent & Substitute Parts
Part Overview
The TSV6291ICT is a general-purpose operational amplifier manufactured by STMicroelectronics, housed in a 5-TSSOP SC-70-5 surface mount package. This single-circuit rail-to-rail amplifier operates across a supply voltage range of 1.5 V to 5.5 V and is rated for temperatures from -40°C to 125°C. The device is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).
Equivalent and substitute parts are identified based on matching functional characteristics: single-circuit general-purpose amplifier topology, rail-to-rail output configuration, identical SC-70-5 package format, and compatible operating temperature and supply voltage parameters. Substitutes are selected when electrical performance parameters fall within acceptable ranges for the application.

Engineering Selection Recommendations
Tier 1 - Direct Substitutes (Preferred):
LMV301MG/NOPB and LMV301MGX/NOPB are functionally equivalent to TSV6291ICT for applications where the maximum supply voltage of 5.0 V is acceptable. Both devices maintain rail-to-rail output, single-circuit topology, and SC-70-5 packaging. These parts offer superior input offset voltage (900 µV vs. 6 mV) and lower input bias current (0.182 pA vs. 1 pA). Both are RoHS3 compliant and active products. The primary limitation is the reduced maximum operating temperature (85°C vs. 125°C) and minimum supply voltage requirement of 1.8 V instead of 1.5 V.
LMV321IDCKT and LMV321M7/NOPB provide extended temperature operation to 125°C matching the TSV6291ICT. These devices feature higher slew rate (1.0 V/µs vs. 0.5 V/µs) and improved output drive capability (160 mA vs. 74 mA). Both maintain full supply voltage range compatibility (2.7 V to 5.5 V minimum to maximum). LMV321M7X/NOPB offers identical electrical performance with Tape & Reel packaging. All three are RoHS3 compliant and active products.
Tier 2 - Functional Equivalents (Application-Dependent):
LMV611MG/NOPB and LMV611MGX/NOPB extend the minimum supply voltage to 1.8 V and provide extended temperature operation (-40°C to 125°C). These devices feature higher gain bandwidth product (1.5 MHz vs. 1.3 MHz) and lower input offset voltage (1 mV vs. 6 mV). Supply current is lower (116 µA vs. 30 µA), and output drive capability is 100 mA. Both are RoHS3 compliant and active products. The slew rate is reduced to 0.42 V/µs.
LMV821M7/NOPB is suitable for applications requiring higher bandwidth (5.6 MHz) and faster slew rate (2.0 V/µs). This device operates across 2.5 V to 5.5 V supply range with -40°C to 85°C temperature rating. Supply current consumption is significantly higher (300 µA). The device is RoHS3 compliant and active. LMV821M7X is electrically identical but carries "Not For New Designs" status and RoHS non-compliance, making it unsuitable for new applications.
LMV321IDCKR (UMW manufacturer) provides voltage feedback topology with 1 MHz bandwidth and operates across 2.1 V to 5.5 V supply range. Operating temperature is limited to -25°C to 85°C. Output drive capability is reduced to 25 mA. This device is RoHS3 compliant and active but represents a lower-performance alternative.
Compliance and Status Considerations:
All recommended substitutes maintain RoHS3 compliance and REACH unaffected status. The TSV6291ICT, LMV301 series, LMV321 series, and LMV611 series are all active products suitable for new designs. LMV821M7X carries "Not For New Designs" status and RoHS non-compliance and is not recommended for new applications.
Moisture sensitivity level (MSL 1 - Unlimited) is maintained across all recommended substitutes except LMV321IDCKT, which carries MSL 2 (1 Year) rating.
Frequently Asked Questions (FAQ)
Q: Can LMV301MG/NOPB directly replace TSV6291ICT in all applications?
A: LMV301MG/NOPB is electrically compatible for applications operating at supply voltages between 1.8 V and 5.0 V and temperatures up to 85°C. The maximum supply voltage is reduced from 5.5 V to 5.0 V. If your application requires operation at 5.5 V supply or temperatures above 85°C, alternative substitutes such as LMV321IDCKT or LMV611MG/NOPB are required.
Q: What is the difference between LMV321M7/NOPB and LMV321M7X/NOPB?
A: Both devices are electrically identical with identical electrical specifications, package format (SC-70-5), and RoHS3 compliance. The primary difference is packaging: LMV321M7/NOPB is supplied in Cut Tape (CT) & Digi-Reel format, while LMV321M7X/NOPB is supplied in Tape & Reel (TR) format. Selection depends on your procurement and assembly requirements.
Q: Why does LMV821M7X show "Not For New Designs" status?
A: LMV821M7X is marked "Not For New Designs" and carries RoHS non-compliance status. This designation indicates the manufacturer is discontinuing support for new applications. For new designs, use LMV821M7/NOPB, which is RoHS3 compliant and carries active product status, or select alternative substitutes from the Tier 1 or Tier 2 categories.
Q: Are all substitute parts available in SC-70-5 package?
A: Yes. All listed substitute parts are housed in 5-TSSOP, SC-70-5, SOT-353 package format, ensuring mechanical and electrical compatibility with TSV6291ICT PCB layouts. No package conversion or board redesign is required.
Q: Which substitute offers the lowest power consumption?
A: TSV6291ICT itself offers the lowest supply current at 30 µA. Among substitutes, LMV321IDCKR provides the next lowest at 45 µA. If power consumption is critical, verify that the reduced output drive capability (25 mA) of LMV321IDCKR meets your application requirements.
Q: Can I use LMV611MG/NOPB in applications requiring operation below 1.8 V?
A: No. LMV611MG/NOPB minimum supply voltage is 1.8 V. TSV6291ICT operates down to 1.5 V. If your application requires operation below 1.8 V, TSV6291ICT or equivalent parts with 1.5 V minimum rating must be used.
Q: What is the impact of different slew rates on circuit performance?
A: Slew rate determines the maximum rate of output voltage change. TSV6291ICT has 0.5 V/µs slew rate. Substitutes with higher slew rates (LMV321 series at 1.0 V/µs, LMV821 series at 2.0 V/µs) support faster signal transitions and higher frequency operation. Substitutes with lower slew rates (LMV611 series at 0.42 V/µs) are suitable for lower-frequency applications. Verify slew rate compatibility with your signal bandwidth requirements.
Q: Are there inventory considerations when selecting substitutes?
A: Inventory levels vary significantly. TSV6291ICT has 50,400 units in stock. Among substitutes, LMV321IDCKR offers the highest inventory (95,100 units), while LMV821M7/NOPB has the lowest (3,955 units). Verify current inventory status with your supplier for production planning.
Q: What is the significance of input offset voltage differences?
A: Input offset voltage is the DC voltage difference between the two input terminals when the output is zero. TSV6291ICT has 6 mV offset. Substitutes range from 800 µV (LMV321IDCKR) to 3.5 mV (LMV821 series). Lower offset voltage reduces DC errors in precision applications. For general-purpose applications, differences are typically negligible.
Q: Can I mix different substitute parts in the same design?
A: All substitute parts are pin-compatible in SC-70-5 package and functionally equivalent for general-purpose amplifier applications. However, electrical performance differences (slew rate, bandwidth, supply current, output drive) may affect circuit behavior. Verify that all selected parts meet the complete set of application requirements before mixing in production.
