TLC27M2ACPG4 Equivalent & Substitute Parts

Part Overview

The TLC27M2ACPG4 is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, part of the LinCMOS™ series. This device integrates two independent amplifier circuits in an 8-pin DIP package with through-hole mounting. The TLC27M2ACPG4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC27M2ACPG4 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: CMOS
• Number of Circuits: 2
• Slew Rate: 0.62 V/µs
• Gain Bandwidth Product: 635 kHz
• Current - Input Bias: 0.7 pA
• Voltage - Input Offset: 900 µV
• Current - Supply: 285 µA (x2 Channels)
• Current - Output / Channel: 30 mA
• Operating Temperature: 0°C ~ 70°C (TA)

Mechanical Compatibility Criteria:

• Base Product Number: TLC27M2
• Mounting Type: Through Hole or Surface Mount
• Package Type: 8-DIP or 8-SOIC
• Compliance: ROHS3, REACH Unaffected

Supply Voltage Consideration: The TLC27M2ACPG4 operates with a minimum supply voltage of 3 V. Substitute parts must support the application's supply voltage requirements within the specified range.

Two substitute parts meet these criteria with variations in packaging and product status.

Parameter Comparison

Engineering Selection Recommendations

TLC27M2ACDR (Surface Mount, 8-SOIC): This substitute is the manufacturer-recommended replacement for the TLC27M2ACPG4. The TLC27M2ACDR maintains identical electrical specifications and is currently in Active product status with high inventory availability (10,084 pcs). The primary difference is the package format: 8-SOIC surface mount versus 8-DIP through-hole. Selection of this part requires PCB redesign to accommodate surface-mount soldering. The minimum supply voltage is 4 V, which is 1 V higher than the main part; applications requiring 3 V operation must use the TLC27M2ACP instead. This part is suitable for new designs and high-volume production requiring surface-mount technology.

TLC27M2ACP (Through Hole, 8-DIP): This substitute maintains the same through-hole 8-DIP package as the TLC27M2ACPG4, enabling direct PCB compatibility without layout modifications. Electrical specifications are identical, including the 3 V minimum supply voltage. The TLC27M2ACP is designated Last Time Buy, indicating limited future availability. Inventory is available (2,168 pcs). This part is suitable for applications requiring through-hole mounting and 3 V minimum supply voltage operation. Selection should account for the Last Time Buy status and plan accordingly for long-term component sourcing.

Both substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original part.

Frequently Asked Questions (FAQ)

Q: Can the TLC27M2ACDR be used as a direct replacement for the TLC27M2ACPG4?

A: The TLC27M2ACDR is electrically equivalent but requires PCB redesign. The main part uses 8-DIP through-hole packaging, while the TLC27M2ACDR uses 8-SOIC surface-mount packaging. Additionally, the TLC27M2ACDR has a minimum supply voltage of 4 V compared to 3 V for the TLC27M2ACPG4. Direct substitution on existing PCBs is not possible without layout modification.

Q: What is the difference between TLC27M2ACP and TLC27M2ACPG4?

A: Both parts use identical 8-DIP through-hole packaging and support 3 V minimum supply voltage. The primary difference is product status: TLC27M2ACPG4 is discontinued at DiGi Electronics, while TLC27M2ACP is Last Time Buy. Electrical specifications are identical. The TLC27M2ACP can be used as a direct replacement on existing PCBs.

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

A: For new designs, the TLC27M2ACDR is recommended due to its Active product status and high inventory availability. This part requires surface-mount PCB design. If through-hole mounting is required, the TLC27M2ACP is suitable, though its Last Time Buy status should be considered for long-term production planning.

Q: Is the 1 V difference in minimum supply voltage between TLC27M2ACPG4 and TLC27M2ACDR significant?

A: Yes. If your application operates at 3 V supply voltage, the TLC27M2ACDR cannot be used. The TLC27M2ACP maintains the 3 V minimum specification and is the appropriate substitute for 3 V applications.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. The TLC27M2ACPG4, TLC27M2ACDR, and TLC27M2ACP are all ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available for these parts?

A: TLC27M2ACPG4 and TLC27M2ACP are supplied in 8-DIP through-hole packages. TLC27M2ACDR is supplied in 8-SOIC surface-mount package. Packaging options are Tape & Reel for TLC27M2ACDR and Tube for TLC27M2ACP.
