TLV2461ID Equivalent & Substitute Parts

Part Overview

The TLV2461ID is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications across industrial, consumer, and automotive sectors. The TLV2461ID is classified as obsolete; however, it remains in stock with 2450 units available. Due to its obsolete status, identifying functionally equivalent and compatible substitute components is essential for design continuity, long-term supply chain reliability, and new product development initiatives.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended for Immediate Substitution):

TLV2461IDR is the primary substitute for TLV2461ID. Both components are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 8-SOIC package. The only difference is packaging format: TLV2461ID is supplied in Tube, while TLV2461IDR is supplied in Tape & Reel (TR). TLV2461IDR maintains Active product status with 2000 units in stock, ensuring long-term availability and supply chain continuity. This substitution requires no circuit redesign and is fully pin-compatible.

Tier 2 - Cross-Manufacturer Substitutes (Performance-Equivalent):

MCP6281-E/SN, MCP6281T-E/SN, MCP6283-E/SN, and MCP6283T-E/SN (Microchip Technology) are functionally equivalent substitutes. These devices meet all mandatory compatibility criteria and exceed the TLV2461ID in slew rate (2.5 V/µs vs. 1.6 V/µs) and input bias current (0.001 nA vs. 1.3 nA). Operating temperature range extends to -40°C to 125°C, matching the original specification. Supply voltage range is 2.2 V to 6 V, which encompasses the TLV2461ID requirement of 2.7 V to 6 V. These parts are available in both Tube and Tape & Reel packaging with inventory levels ranging from 1109 to 3947 units.

TSV911AIDT (STMicroelectronics) is a high-performance alternative with superior slew rate (4.5 V/µs) and gain bandwidth product (8 MHz). It maintains the -40°C to 125°C operating range and offers exceptional input bias current performance (0.001 nA). Supply voltage range is 2.5 V to 5.5 V, which is compatible with the TLV2461ID specification. With 25200 units in stock, this part provides excellent supply availability. Packaging is Cut Tape & Digi-Reel format.

Tier 3 - Limited Compatibility Substitutes:

MAX4091ASA+ and MAX4091ASA+T (Analog Devices Inc./Maxim Integrated) meet package and mounting requirements but exhibit significantly reduced performance in slew rate (0.2 V/µs) and gain bandwidth product (0.5 MHz). These parts are suitable only for applications where lower bandwidth and slower signal processing are acceptable. Operating temperature range is -40°C to 125°C, and supply voltage range is 2.7 V to 6 V.

MAX4322ESA+ and MAX4322ESA+T (Analog Devices Inc./Maxim Integrated) have a reduced operating temperature maximum of 85°C, which does not meet the TLV2461ID specification of 125°C. These parts are not recommended for applications requiring the full -40°C to 125°C temperature range.

All substitute components are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q1: Can TLV2461IDR be used as a direct replacement for TLV2461ID?

A: Yes. TLV2461IDR is the direct substitute manufactured by Texas Instruments. Both parts have identical electrical specifications, pin configuration, and 8-SOIC package dimensions. The only difference is packaging format: TLV2461ID is supplied in Tube, while TLV2461IDR is supplied in Tape & Reel (TR). No circuit modifications are required.

Q2: What are the key differences between TLV2461ID and the Microchip MCP6281/MCP6283 series?

A: The MCP6281 and MCP6283 devices offer improved performance in slew rate (2.5 V/µs vs. 1.6 V/µs) and significantly lower input bias current (0.001 nA vs. 1.3 nA). However, input offset voltage is higher (3 mV vs. 500 µV), and output current per channel is lower (25 mA vs. 80 mA). Both families are pin-compatible in the 8-SOIC package and support the same -40°C to 125°C operating range. Selection depends on whether the application prioritizes low input bias current or high output drive capability.

Q3: Is TSV911AIDT suitable for all TLV2461ID applications?

A: TSV911AIDT is suitable for most applications requiring general-purpose amplification. It exceeds TLV2461ID performance in slew rate (4.5 V/µs vs. 1.6 V/µs) and gain bandwidth product (8 MHz vs. 6.4 MHz). However, the supply voltage maximum is 5.5 V compared to 6 V for TLV2461ID. Applications requiring operation above 5.5 V supply voltage must use alternative substitutes. Pin configuration and 8-SOIC package are identical.

Q4: Why is MAX4091ASA+ listed as a substitute if its performance is lower?

A: MAX4091ASA+ meets all mandatory compatibility criteria: 8-SOIC package, rail-to-rail output, single-circuit configuration, -40°C to 125°C operating range, and 2.7 V to 6 V supply voltage. It is included for applications where lower bandwidth and reduced slew rate are acceptable or beneficial, such as low-frequency signal conditioning or power-constrained designs. The 130 µA supply current is significantly lower than TLV2461ID (550 µA), making it suitable for battery-powered applications.

Q5: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual handling and small-quantity applications, while Tape & Reel (TR) packaging is designed for automated pick-and-place assembly. Both formats contain identical components in the same 8-SOIC package. Selection depends on manufacturing process: manual assembly typically uses Tube, while high-volume production uses Tape & Reel. Electrical performance and reliability are identical between packaging formats.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute components listed—TLV2461IDR, MAX4091ASA+, MAX4091ASA+T, MAX4322ESA+, MAX4322ESA+T, MCP6281-E/SN, MCP6281T-E/SN, MCP6283-E/SN, MCP6283T-E/SN, and TSV911AIDT—are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). This matches the compliance profile of the original TLV2461ID.

Q7: Which substitute offers the best supply availability?

A: TSV911AIDT from STMicroelectronics has the highest inventory level with 25200 units in stock. Among Texas Instruments and Microchip alternatives, MCP6281T-E/SN has 3947 units and MAX4322ESA+ has 3227 units available. TLV2461IDR, the direct replacement, has 2000 units in stock.

Q8: Can MAX4322ESA+ be used in applications requiring -40°C to 125°C operation?

A: No. MAX4322ESA+ and MAX4322ESA+T have a maximum operating temperature of 85°C, which does not meet the TLV2461ID specification of 125°C. These parts are not suitable for applications requiring the full extended temperature range. Use TLV2461IDR, MCP6281/MCP6283 series, or TSV911AIDT for full -40°C to 125°C operation.
