TLC27M2CPS CMOS Amplifier Equivalent & Substitute Parts

Part Overview

The TLC27M2CPS is a dual-channel CMOS amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SO surface mount package. This device is classified as a LinCMOS™ series component and is currently in Last Time Buy status, indicating discontinued production with limited remaining inventory.

The TLC27M2CPS requires substitute identification due to its Last Time Buy product status. Organizations requiring continued supply of dual-channel CMOS amplifier functionality must transition to alternative part numbers that maintain electrical and mechanical compatibility while offering active production status or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27M2CPS is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: CMOS technology
• Number of Circuits: Dual-channel (2 circuits)
• Slew Rate: 0.62 V/µs minimum
• Gain Bandwidth Product: 635 kHz minimum
• Input Bias Current: 0.7 pA maximum
• Input Offset Voltage: 1.1 mV maximum
• Supply Current: 285 µA (x2 Channels) maximum
• Output Current per Channel: 30 mA minimum
• Supply Voltage Range: 3 V to 16 V
• Operating Temperature: 0°C to 70°C minimum

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package Type: 8-SOIC configuration
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Criteria:

• RoHS3 Compliance required
• REACH Unaffected status

Substitute parts must satisfy all electrical parameters within the specified ranges and maintain mechanical compatibility with the original package footprint. Parts with superior electrical performance (higher bandwidth, lower bias current, wider temperature range) are acceptable substitutes provided they do not exceed maximum ratings.

Parameter Comparison

Engineering Selection Recommendations

TLC27M2CDR (Primary Substitute)

The TLC27M2CDR is the manufacturer-recommended substitute for the TLC27M2CPS. This part maintains identical electrical specifications across all critical parameters: CMOS amplifier type, dual-channel configuration, 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 30 mA output current per channel. Both parts operate across the 3 V to 16 V supply range and share the 0°C to 70°C operating temperature specification.

The TLC27M2CDR differs from the TLC27M2CPS in packaging width (0.154" versus 0.209") and product status. The TLC27M2CDR is in Active production status with significantly higher inventory availability (55,100 pieces versus 1,834 pieces), ensuring long-term supply continuity. Both parts are ROHS3 compliant with MSL 1 rating and share the LinCMOS™ series designation.

LM432MA/NOPB (Secondary Substitute)

The LM432MA/NOPB is a general-purpose amplifier that meets the dual-channel, 30 mA output current, and 8-SOIC package requirements. This part offers superior electrical performance in several parameters: 1 MHz gain bandwidth product (versus 635 kHz), 3 nA input bias current (versus 0.7 pA), and 600 µV input offset voltage (versus 1.1 mV). The LM432MA/NOPB also provides lower supply current consumption at 150 µA (x2 Channels) and extended operating temperature range of -40°C to 85°C.

However, the LM432MA/NOPB carries Obsolete product status with limited inventory (869 pieces). This part is not recommended for new designs or long-term production applications. The LM432MA/NOPB is suitable only for legacy system maintenance where existing designs have validated this component.

Compliance and Certification Status

All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Frequently Asked Questions (FAQ)

Q: Can the TLC27M2CDR directly replace the TLC27M2CPS on existing printed circuit boards?

A: The TLC27M2CDR is electrically equivalent to the TLC27M2CPS across all specified parameters. However, the package width differs (0.154" versus 0.209"), which may affect PCB footprint compatibility. Verify that the PCB layout accommodates the narrower 8-SOIC package before implementing this substitution. Pin configuration and spacing remain identical.

Q: What is the significance of the Last Time Buy status for the TLC27M2CPS?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLC27M2CPS and will not accept new orders beyond a specified cutoff date. Existing inventory will be depleted without replenishment. Organizations dependent on this part number must transition to the TLC27M2CDR or identify alternative solutions before inventory exhaustion.

Q: Is the LM432MA/NOPB suitable for new product designs?

A: No. The LM432MA/NOPB carries Obsolete product status, indicating discontinued production with no future availability. This part is appropriate only for maintenance and repair of existing systems that have validated this component. New designs must utilize the TLC27M2CDR or other active-status alternatives.

Q: What are the key electrical differences between the TLC27M2CDR and LM432MA/NOPB?

A: The TLC27M2CDR maintains CMOS amplifier architecture with 0.62 V/µs slew rate and 635 kHz bandwidth. The LM432MA/NOPB is a general-purpose amplifier with higher 1 MHz bandwidth, lower input bias current (3 nA versus 0.7 pA), and lower input offset voltage (600 µV versus 1.1 mV). The LM432MA/NOPB also operates at lower supply current (150 µA versus 285 µA) and supports extended temperature range (-40°C to 85°C versus 0°C to 70°C).

Q: Are there packaging considerations when substituting the TLC27M2CPS?

A: Yes. The TLC27M2CPS uses an 8-SOIC package with 0.209" width, while both substitute parts use 0.154" width 8-SOIC packages. PCB footprints must be verified for compatibility. Pin count, spacing, and electrical connections remain identical across all three parts. Consult PCB layout documentation to confirm that the narrower package width does not conflict with adjacent components or trace routing.

Q: Do all three parts meet RoHS3 compliance requirements?

A: Yes. The TLC27M2CPS, TLC27M2CDR, and LM432MA/NOPB are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8542.33.0001.

Q: What supply voltage range is supported across all substitute options?

A: The TLC27M2CPS and TLC27M2CDR support 3 V to 16 V supply range. The LM432MA/NOPB supports a wider range of 2.5 V to 16 V, allowing operation at lower supply voltages. Verify that your application supply voltage falls within the supported range of your selected substitute part.
