Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC27M9CD are grouped based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

Mandatory Compatibility Parameters:

• Amplifier Type: CMOS
• Number of Circuits: 4
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span: 3V to 16V minimum
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Substitution Categories:

Category 1: Direct Packaging Equivalent (Tube to Tape & Reel) The TLC27M9CDR represents the same base product (TLC27M9) with identical electrical specifications but supplied in Tape & Reel packaging instead of Tube. This part maintains all electrical parameters and is suitable for high-volume automated assembly processes.

Category 2: Lower Performance / Lower Power Consumption The TS27L4 series (TS27L4CDT, TS27L4AIDT, TS27L4IDT) provides CMOS 4-circuit amplifiers with reduced slew rate (0.04V/µs vs. 0.62V/µs), lower gain bandwidth product (100 kHz vs. 525 kHz), and significantly lower supply current (10µA vs. 570µA). These parts are suitable for applications where lower power consumption and reduced bandwidth requirements are acceptable.

Category 3: Higher Performance / Higher Power Consumption The TS27M4 series (TS27M4CDT, TS27M4IDT) provides CMOS 4-circuit amplifiers with higher slew rate (0.6V/µs) and higher gain bandwidth product (1 MHz) compared to the TLC27M9CD, with moderately increased supply current (150µA vs. 570µA). These parts are suitable for applications requiring enhanced frequency response.

All substitute parts maintain the 14-SOIC package footprint, surface mount compatibility, and supply voltage range required for direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): The TLC27M9CDR is the primary recommended substitute. This part maintains all electrical specifications of the TLC27M9CD while offering Active product status and higher inventory availability (15,301 pcs vs. 989 pcs). The only difference is packaging format (Tape & Reel vs. Tube), which affects assembly process compatibility but not electrical performance or board-level functionality. This substitution is appropriate for all applications currently using TLC27M9CD.

For Power-Constrained Applications: The TS27L4 series (TS27L4CDT, TS27L4AIDT, TS27L4IDT) is suitable when reduced power consumption is a design requirement. These parts consume 10µA total supply current compared to 570µA for the TLC27M9CD, representing a 57-fold reduction. The trade-off is reduced slew rate (0.04V/µs vs. 0.62V/µs) and lower gain bandwidth product (100 kHz vs. 525 kHz). Applications limited by power budget or thermal constraints may benefit from this substitution. The TS27L4AIDT and TS27L4IDT support extended operating temperature range (-40°C to 125°C) compared to the TLC27M9CD (0°C to 70°C).

For Higher Bandwidth Applications: The TS27M4 series (TS27M4CDT, TS27M4IDT) provides increased gain bandwidth product (1 MHz vs. 525 kHz) and slew rate (0.6V/µs vs. 0.62V/µs) with moderate supply current increase (150µA vs. 570µA). This substitution is appropriate for applications requiring enhanced frequency response. The TS27M4IDT supports extended operating temperature range (-40°C to 125°C).

Compliance and Regulatory Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications as the TLC27M9CD. No regulatory or compliance barriers exist for substitution.

Inventory and Availability: The TLC27M9CDR offers the highest inventory availability (15,301 pcs) among all substitutes, followed by TS27L4CDT (30,200 pcs) and TS27L4IDT (23,400 pcs). The original TLC27M9CD is limited to 989 pcs and designated Last Time Buy, making alternative sourcing strategically important for long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can I use TLC27M9CDR as a direct replacement for TLC27M9CD on my PCB?

A: Yes. The TLC27M9CDR is electrically and mechanically identical to the TLC27M9CD. Both use the 14-SOIC package with identical pinout, electrical specifications, and operating characteristics. The only difference is the packaging format (Tape & Reel vs. Tube), which affects how components are supplied and handled during assembly but does not affect board-level performance.

Q: What are the key differences between the TS27L4 series and the TLC27M9CD?

A: The TS27L4 series offers significantly lower power consumption (10µA vs. 570µA total supply current) but with reduced performance specifications. Slew rate is 0.04V/µs compared to 0.62V/µs, and gain bandwidth product is 100 kHz compared to 525 kHz. Input offset voltage is higher (900–1100 µV vs. 210 µV). These parts are suitable for low-power applications where bandwidth and precision requirements are less stringent.

Q: Can I substitute TS27M4 parts for TLC27M9CD in high-frequency applications?

A: The TS27M4 series provides higher gain bandwidth product (1 MHz vs. 525 kHz) and comparable slew rate (0.6V/µs vs. 0.62V/µs), making it suitable for applications requiring enhanced frequency response. However, supply current is higher (150µA vs. 570µA), and input offset voltage is higher (1100 µV vs. 210 µV). Substitution is appropriate only if the application can tolerate these electrical differences.

Q: Are all substitute parts available in the same 14-SOIC package?

A: Yes. All substitute parts listed use the 14-SOIC (0.154", 3.90mm Width) surface mount package. This ensures mechanical and footprint compatibility with existing PCB designs. Pinout and package dimensions are identical across all parts, allowing direct board-level substitution without layout modifications.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are different supply formats for the same component. Tape & Reel is supplied on continuous carrier tape suitable for high-speed automated pick-and-place assembly. Cut Tape is supplied in shorter tape segments suitable for lower-volume assembly or manual handling. Both formats contain identical components; the difference is in supply logistics and assembly process compatibility.

Q: Why is the TLC27M9CD designated as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer (Texas Instruments) will discontinue production of this part. Existing inventory will be sold until depletion, after which the part will no longer be available. This designation makes identifying and qualifying substitute parts essential for ensuring long-term design continuity and supply chain reliability.

Q: Can I use TS27L4AIDT or TS27M4IDT in applications requiring extended temperature operation?

A: Yes. Both TS27L4AIDT and TS27M4IDT support operating temperature range of -40°C to 125°C, compared to 0°C to 70°C for the TLC27M9CD. These parts are suitable for applications requiring extended temperature operation. The TS27L4CDT and TS27M4CDT maintain the 0°C to 70°C range matching the original part.

Q: Are there any compliance or regulatory differences between substitute parts?

A: No. All substitute parts maintain identical compliance status: ROHS3 Compliant, MSL Level 1 (Unlimited), REACH Unaffected, ECCN EAR99, and HTSUS 8542.33.0001. No regulatory or compliance barriers exist for substitution between any of these parts.

Q: Which substitute part should I select for a new design?

A: For new designs, the TLC27M9CDR is recommended as the primary choice, offering identical electrical performance to the TLC27M9CD with Active product status and high availability. If power consumption is critical, evaluate the TS27L4 series. If higher bandwidth is required, evaluate the TS27M4 series. All parts are ROHS3 compliant and suitable for production use.
