TLC27M2ID CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The TLC27M2ID is a dual-channel CMOS operational amplifier manufactured by Texas Instruments in the LinCMOS™ series, packaged in 8-SOIC surface mount configuration. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC27M2ID serves applications requiring low-power CMOS amplification with dual independent circuits in a compact form factor.

Substitute parts are necessary due to product status transition and inventory availability. Alternative models maintain functional equivalence through matching electrical specifications and mechanical compatibility while offering active production status or improved availability.

Substitute Part Grouping Explanation

Substitute parts for the TLC27M2ID are classified into two functional categories based on electrical parameter alignment:

Category 1: Direct Electrical Equivalents (Identical Specifications) Parts maintaining identical slew rate (0.62 V/µs), gain bandwidth product (635 kHz), input bias current (0.7 pA), and supply current (285 µA per dual channels). These parts preserve exact circuit performance characteristics and require no design modification.

Category 2: Enhanced Performance Alternatives (Superior Specifications) Parts with improved electrical performance including higher slew rate (5.5 V/µs), higher gain bandwidth product (3.5 MHz), lower input offset voltage (250 µV to 900 µV), and higher output current capability (45 mA per channel). These parts operate within the same supply voltage range (3-16 V minimum to maximum) and maintain 8-SOIC package compatibility but deliver enhanced performance margins.

Category 3: Low-Power Variants (Reduced Supply Current) Parts with significantly reduced supply current (10 µA per dual channels) and lower gain bandwidth product (100 kHz), suitable for power-constrained applications where the TLC27M2ID's performance specifications exceed application requirements.

Substitution validity is determined by: (1) matching package type (8-SOIC surface mount), (2) dual-circuit CMOS architecture, (3) compatible supply voltage range overlap, and (4) operating temperature range coverage of the original application requirement.

Engineering Selection Recommendations

Primary Substitute: TLC27M2IDR

The TLC27M2IDR is the direct functional equivalent manufactured by Texas Instruments. This part maintains identical electrical specifications across all measured parameters: 0.62 V/µs slew rate, 635 kHz gain bandwidth product, 0.7 pA input bias current, 1.1 mV input offset voltage, and 285 µA supply current. The TLC27M2IDR differs only in packaging format (Cut Tape & Digi-Reel® versus Tube) and product status (Active versus Last Time Buy). Both parts are ROHS3 compliant with MSL 1 rating. Selection of TLC27M2IDR is appropriate for applications requiring exact performance preservation with improved long-term availability.

Secondary Substitutes: TS272 Series (STMicroelectronics)

The TS272 family (TS272ACDT, TS272AIDT, TS272BIDT, TS272CDT, TS272IDT) provides enhanced performance characteristics suitable for applications where improved performance margins are beneficial. These parts deliver 5.5 V/µs slew rate (8.9× improvement), 3.5 MHz gain bandwidth product (5.5× improvement), and 45 mA output current per channel (1.5× improvement) compared to TLC27M2ID. Supply current increases to 1 mA per dual channels. Operating temperature range varies by grade: TS272ACDT and TS272CDT operate 0°C to 70°C; TS272AIDT, TS272BIDT, and TS272IDT operate -40°C to 125°C. All TS272 variants maintain 8-SOIC package compatibility and 3-16 V supply voltage range. Selection is appropriate when circuit design permits higher supply current consumption in exchange for enhanced bandwidth and slew rate performance.

Tertiary Substitutes: TS27L2 Series (STMicroelectronics)

The TS27L2 family (TS27L2ACDT, TS27L2AIDT, TS27L2BIDT) addresses ultra-low-power applications where supply current reduction is critical. These parts consume only 10 µA per dual channels (28× reduction) with corresponding reduction in gain bandwidth product to 100 kHz and slew rate to 0.04 V/µs. Operating temperature range varies: TS27L2ACDT operates 0°C to 70°C; TS27L2AIDT and TS27L2BIDT operate -40°C to 125°C. Selection is appropriate only when application bandwidth requirements are compatible with 100 kHz maximum gain bandwidth product and power consumption reduction is a primary design objective.

All substitute parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating. Package compatibility is confirmed for all 8-SOIC surface mount variants.

Frequently Asked Questions (FAQ)

Q1: Can TLC27M2IDR be used as a direct replacement for TLC27M2ID without circuit modification?

Yes. TLC27M2IDR maintains identical electrical specifications: 0.62 V/µs slew rate, 635 kHz gain bandwidth product, 0.7 pA input bias current, 1.1 mV input offset voltage, 285 µA supply current, and -40°C to 85°C operating temperature range. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube) and product status. No circuit design changes are required.

Q2: What are the key differences between TLC27M2ID and TS272 series substitutes?

TS272 series parts provide significantly enhanced performance: 5.5 V/µs slew rate versus 0.62 V/µs, 3.5 MHz gain bandwidth product versus 635 kHz, and 45 mA output current per channel versus 30 mA. Supply current increases from 285 µA to 1 mA per dual channels. Operating temperature range is extended to -40°C to 125°C for certain grades. These improvements are suitable for applications requiring higher bandwidth and faster signal response, provided the increased supply current is acceptable.

Q3: Are TS27L2 series parts suitable as direct replacements?

TS27L2 series parts are not direct replacements. While they maintain 8-SOIC package compatibility and dual-circuit CMOS architecture, they operate at significantly reduced bandwidth (100 kHz versus 635 kHz) and slew rate (0.04 V/µs versus 0.62 V/µs). Selection is appropriate only when application bandwidth requirements are compatible with these reduced specifications and ultra-low power consumption (10 µA versus 285 µA) is a primary design objective.

Q4: What is the operating temperature range compatibility for substitution?

TLC27M2ID operates -40°C to 85°C. TLC27M2IDR maintains this range. TS272ACDT and TS272CDT operate 0°C to 70°C (narrower range). TS272AIDT, TS272BIDT, TS272IDT, TS27L2AIDT, and TS27L2BIDT operate -40°C to 125°C (extended range). Substitution is valid when the substitute part's operating temperature range fully encompasses the application's required temperature range.

Q5: Are all substitute parts RoHS3 compliant?

Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the TLC27M2ID compliance profile.

Q6: What packaging format differences exist among substitutes?

TLC27M2ID is supplied in Tube packaging. TLC27M2IDR is supplied in Cut Tape & Digi-Reel®. TS272ACDT and TS27L2ACDT are supplied in Cut Tape & Digi-Reel®. TS272AIDT, TS272BIDT, TS272IDT, TS27L2AIDT, and TS27L2BIDT are supplied in Tape & Reel. All parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount package. Packaging format selection depends on assembly process requirements and volume quantities.

Q7: Which substitute offers the best inventory availability?

TS272CDT offers the highest inventory level at 17,007 pieces. TS272IDT provides 21,553 pieces. TS27L2BIDT offers 10,353 pieces. TLC27M2IDR provides 7,656 pieces. Inventory levels should be verified at time of procurement as quantities change continuously.
