Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC27M4ACDR are qualified based on the following criteria:

Package Compatibility: All substitute parts utilize the 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and electrical pin compatibility with the original design.

Supply Voltage Range: All substitutes operate within the 3 V to 16 V supply span, maintaining compatibility with existing power distribution architectures.

Circuit Count: All substitute parts contain four independent amplifier circuits, preserving functional density and board layout requirements.

Surface Mount Technology: All candidates employ surface mount mounting technology, supporting automated assembly processes.

Compliance Standards: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Electrical Performance Boundaries: Substitutes are grouped by slew rate and gain bandwidth product characteristics, which determine suitability for specific signal processing applications. The TLC27M4ACDR operates at 0.62 V/µs slew rate and 525 kHz gain bandwidth product. Substitute parts are available in lower-performance (0.04 V/µs, 100 kHz) and higher-performance (0.6 V/µs, 1 MHz) variants, each serving distinct application requirements.

Parameter Comparison

Engineering Selection Recommendations

TS27L4AIDT (STMicroelectronics): This substitute operates across an extended temperature range (-40°C to 125°C) compared to the TLC27M4ACDR (0°C to 70°C). The TS27L4AIDT exhibits significantly lower supply current (10 µA versus 570 µA) and reduced slew rate (0.04 V/µs versus 0.62 V/µs). Selection is appropriate for applications prioritizing power efficiency and extended temperature operation where reduced signal bandwidth is acceptable. Packaging is Tape & Reel (TR).

TS27L4CDT (STMicroelectronics): This substitute maintains the same operating temperature range as the TLC27M4ACDR (0°C to 70°C) and shares identical supply voltage specifications. The TS27L4CDT provides substantially lower supply current consumption (10 µA) and reduced slew rate (0.04 V/µs). Input offset voltage is specified at 1.1 mV versus 900 µV for the main part. Selection is appropriate for cost-sensitive applications with matching temperature requirements and where power consumption reduction is prioritized. Packaging is Cut Tape (CT) with highest inventory availability (30,200 pcs).

TS27L4IDT (STMicroelectronics): This substitute operates across an extended temperature range (-40°C to 125°C) and provides the lowest supply current (10 µA) among all candidates. Slew rate is 0.04 V/µs with input offset voltage at 1.1 mV. Selection is appropriate for applications requiring extended temperature operation and minimal power consumption where reduced bandwidth is acceptable. Packaging is Cut Tape (CT) & Digi-Reel® with substantial inventory (23,400 pcs).

TS27M4IDT (STMicroelectronics): This substitute provides the highest gain bandwidth product (1 MHz) and slew rate (0.6 V/µs) among all candidates, closely matching the TLC27M4ACDR performance profile. Operating temperature range extends to -40°C to 125°C. Supply current is 150 µA, intermediate between low-power variants and the main part. Selection is appropriate for applications requiring extended temperature operation and higher signal bandwidth performance. Packaging is Cut Tape (CT) with inventory of 7,910 pcs.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the TLC27M4ACDR?

A: Substitution eligibility is determined by package compatibility (14-SOIC), circuit count (4 independent amplifiers), supply voltage range (3 V to 16 V), surface mount technology, and compliance certifications (ROHS3, REACH unaffected). Electrical performance parameters such as slew rate and gain bandwidth product define application suitability but do not prevent substitution if the application requirements align with the substitute's specifications.

Q: Can I use TS27L4CDT as a direct replacement in all applications?

A: The TS27L4CDT shares the same operating temperature range (0°C to 70°C) and package as the TLC27M4ACDR. However, it operates at significantly lower slew rate (0.04 V/µs versus 0.62 V/µs) and gain bandwidth product (100 kHz versus 525 kHz). Direct replacement is appropriate only for applications where these reduced performance parameters are acceptable. Applications requiring higher signal bandwidth or faster transient response require evaluation of TS27M4IDT or continued use of the original part.

Q: What is the advantage of TS27M4IDT over other substitutes?

A: The TS27M4IDT provides the highest gain bandwidth product (1 MHz) and slew rate (0.6 V/µs) among all substitutes, most closely matching the TLC27M4ACDR performance envelope. It also extends operating temperature to -40°C to 125°C. This substitute is selected when extended temperature operation is required without sacrificing signal bandwidth performance.

Q: Why do some substitutes have lower supply current?

A: The TS27L4 series variants (TS27L4AIDT, TS27L4CDT, TS27L4IDT) operate at 10 µA total supply current compared to 570 µA for the TLC27M4ACDR. This reduction reflects different internal circuit architecture and is accompanied by reduced slew rate (0.04 V/µs) and gain bandwidth product (100 kHz). Lower supply current is advantageous in battery-powered or power-constrained applications where bandwidth requirements permit the trade-off.

Q: Are all substitutes available in the same packaging options?

A: No. The TLC27M4ACDR is available in Cut Tape (CT) & Digi-Reel® packaging. Substitutes vary: TS27L4AIDT is Tape & Reel (TR), TS27L4CDT is Cut Tape (CT), TS27L4IDT is Cut Tape (CT) & Digi-Reel®, and TS27M4IDT is Cut Tape (CT). Packaging selection should align with assembly process requirements and inventory management practices.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the TLC27M4ACDR. All parts maintain Active product status, ensuring continued availability and support.

Q: What is the inventory status of each substitute?

A: TS27L4CDT has the highest inventory (30,200 pcs), followed by TS27L4IDT (23,400 pcs), TS27L4AIDT (1,844 pcs), and TS27M4IDT (7,910 pcs). The TLC27M4ACDR maintains 3,900 pcs in stock. Inventory levels should be considered for supply chain planning and lead time management.
