TLC27M2ACP Equivalent & Substitute Parts

Part Overview

The TLC27M2ACP is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, classified within the LinCMOS™ series. This device integrates two independent amplifier circuits in an 8-pin DIP package configured for through-hole mounting. The TLC27M2ACP is designated as Last Time Buy, indicating discontinued production status. Identification of equivalent substitute components becomes necessary for ongoing design support, production continuity, and system maintenance where through-hole or surface-mount alternatives are required.

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27M2ACP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence 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 (per channel)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 3–16 V (or 4–16 V minimum)
• Operating Temperature Range: 0°C to 70°C

Mechanical & Packaging Criteria:

• Base Product Number: TLC27M2
• Package Type: 8-pin DIP or 8-pin SOIC
• Compliance: ROHS3 Compliant, REACH Unaffected

The TLC27M2ACDR qualifies as a direct electrical substitute with identical performance specifications. The primary distinction is packaging format: the main part uses through-hole DIP mounting, while the substitute employs surface-mount SOIC technology. Both devices share the same base product number and electrical characteristics, confirming functional interchangeability within their respective mounting contexts.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The TLC27M2ACP carries Last Time Buy status, indicating production discontinuation. The TLC27M2ACDR is designated Active, confirming ongoing availability and manufacturing support from Texas Instruments.

Electrical Compatibility

All electrical parameters—including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current—are identical between the main part and substitute. Both devices operate across the 0°C to 70°C temperature range and comply with ROHS3 and REACH requirements.

Supply Voltage Consideration

The TLC27M2ACDR specifies a minimum supply voltage of 4 V, compared to 3 V for the TLC27M2ACP. Applications requiring operation below 4 V must retain the original TLC27M2ACP or identify alternative components with lower minimum supply specifications.

Packaging and Mounting Context

Selection between TLC27M2ACP and TLC27M2ACDR depends on circuit board design:

• Through-hole PCB designs: TLC27M2ACP (8-DIP package)
• Surface-mount PCB designs: TLC27M2ACDR (8-SOIC package)

Both packages accommodate the same die and electrical performance. Substitution requires corresponding changes to PCB layout, footprint, and assembly process.

Compliance and Regulatory

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying equivalent regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can TLC27M2ACDR replace TLC27M2ACP in all applications?

A: Electrical replacement is valid when the application supply voltage is 4 V or higher. The substitute provides identical amplifier performance. However, physical replacement requires PCB redesign to accommodate the 8-SOIC surface-mount package instead of the 8-DIP through-hole package.

Q: What is the significance of the Last Time Buy status on TLC27M2ACP?

A: Last Time Buy indicates Texas Instruments has discontinued production of this part number. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. The TLC27M2ACDR, with Active status, represents the recommended path for new designs and ongoing production.

Q: Are there electrical performance differences between the two part numbers?

A: No. Both devices share identical electrical specifications: 0.62 V/µs slew rate, 635 kHz gain bandwidth product, 0.7 pA input bias current, 900 µV input offset voltage, 285 µA supply current per channel, and 30 mA output current per channel.

Q: What is the minimum supply voltage difference, and does it matter?

A: TLC27M2ACP operates from 3 V minimum; TLC27M2ACDR requires 4 V minimum. If your application uses a 3 V supply, the substitute cannot be used. Verify your circuit's supply voltage specification before selecting the substitute.

Q: Can I use TLC27M2ACDR in a through-hole socket designed for TLC27M2ACP?

A: No. The TLC27M2ACDR is a surface-mount 8-SOIC package and cannot be inserted into a through-hole DIP socket. Physical package incompatibility requires PCB redesign and assembly process modification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TLC27M2ACP and TLC27M2ACDR are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What inventory status should I expect?

A: TLC27M2ACP (Last Time Buy) has limited remaining inventory. TLC27M2ACDR (Active) maintains higher stock levels through authorized distributors, supporting both immediate procurement and long-term supply continuity.
