TLC272CPSG4 Equivalent & Substitute Parts

Part Overview

The TLC272CPSG4 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-SOIC surface mount package and is designed for low-power, general-purpose analog signal processing applications requiring rail-to-rail operation across a 3V to 16V supply range.

The TLC272CPSG4 has been discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, amplifier configuration, output current capability, and thermal operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC272CPSG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Dual-channel amplifier configuration (2 circuits minimum)
• Surface mount 8-pin package compatibility
• Supply voltage range encompassing 3V to 16V operation
• Output current capability of 30 mA per channel or greater
• Operating temperature range supporting 0°C to 70°C minimum
• RoHS3 compliance and MSL Level 1 rating

Substitute Parts Identified:

TLC272CPS (Texas Instruments): Manufacturer-recommended substitute. Identical electrical specifications to TLC272CPSG4. Differs only in packaging format (Tube vs. unspecified for main part). Maintains all critical parameters including 5.3V/µs slew rate, 2.2 MHz gain bandwidth product, and 3V to 16V supply range. Product status is Last Time Buy, indicating limited future availability.

LM432MA/NOPB (Texas Instruments): General-purpose dual-channel amplifier with compatible dual-circuit configuration and 8-SOIC package. Operates across 2.5V to 16V supply range, exceeding the minimum 3V requirement of the main part. Supports extended operating temperature range of -40°C to 85°C. Differs in amplifier type classification (General Purpose vs. CMOS), slew rate specification (not provided), and gain bandwidth product (1 MHz vs. 2.2 MHz). Product status is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

TLC272CPS is the primary substitute for TLC272CPSG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including CMOS amplifier type, 2.2 MHz gain bandwidth product, 5.3V/µs slew rate, and 3V to 16V supply range. The parts differ only in packaging format. Both maintain RoHS3 compliance and MSL Level 1 rating. TLC272CPS is currently available with higher inventory (3400 Pcs) compared to TLC272CPSG4 (938 Pcs). However, TLC272CPS carries a Last Time Buy status, indicating that future availability is limited and procurement should be prioritized if long-term supply is required.

LM432MA/NOPB is a secondary substitute option. This part maintains dual-channel configuration, 8-SOIC surface mount package, and 30 mA output current per channel. The supply voltage range extends to 2.5V minimum, providing broader low-voltage compatibility. Operating temperature range extends to -40°C to 85°C, supporting wider thermal environments. However, LM432MA/NOPB differs in critical performance parameters: gain bandwidth product is 1 MHz (versus 2.2 MHz), slew rate is not specified, and amplifier type is classified as General Purpose rather than CMOS. Input bias current is significantly higher at 3 nA versus 0.7 pA. Supply current per channel is substantially lower at 0.15 mA versus 1.9 mA. LM432MA/NOPB carries an Obsolete product status, indicating no further manufacturing or support from the manufacturer. Physical package dimensions differ (0.154" width versus 0.209" width), which may affect PCB layout compatibility.

Compliance and Regulatory Status: All three parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, supporting equivalent regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can TLC272CPS directly replace TLC272CPSG4 in existing designs?

A: Yes. TLC272CPS is electrically and functionally identical to TLC272CPSG4. Both parts share the same base product number (TLC272), identical electrical specifications, and equivalent package dimensions (8-SOIC, 0.209" width). The only difference is packaging format (Tube for TLC272CPS). Direct substitution is supported without circuit modification.

Q: What are the key differences between TLC272CPS and LM432MA/NOPB?

A: Both parts are dual-channel amplifiers in 8-SOIC packages with 30 mA output current capability. TLC272CPS maintains the CMOS amplifier type with 2.2 MHz gain bandwidth product and 5.3V/µs slew rate. LM432MA/NOPB is a General Purpose amplifier with 1 MHz gain bandwidth product and unspecified slew rate. TLC272CPS operates at 1.9 mA supply current per channel; LM432MA/NOPB operates at 0.15 mA, making it more power-efficient. LM432MA/NOPB supports extended temperature range (-40°C to 85°C) and lower minimum supply voltage (2.5V). Physical package width differs: TLC272CPS is 0.209" versus LM432MA/NOPB at 0.154", which may affect PCB layout compatibility.

Q: Is LM432MA/NOPB suitable as a substitute for high-speed applications?

A: LM432MA/NOPB has a lower gain bandwidth product (1 MHz versus 2.2 MHz) and unspecified slew rate compared to TLC272CPSG4 (5.3V/µs). For applications requiring the full 2.2 MHz bandwidth or 5.3V/µs slew rate performance, LM432MA/NOPB does not provide equivalent performance specifications.

Q: What is the impact of LM432MA/NOPB's Obsolete status?

A: Obsolete status indicates that the manufacturer has discontinued production and provides no further support or availability guarantees. While current inventory exists (869 Pcs), future procurement cannot be assured. For designs requiring long-term component availability, TLC272CPS is the preferred substitute, though it carries Last Time Buy status and should be procured promptly.

Q: Are there package compatibility concerns when substituting these parts?

A: TLC272CPS uses an 8-SOIC package with 0.209" width, identical to TLC272CPSG4, ensuring direct PCB compatibility. LM432MA/NOPB uses an 8-SOIC package with 0.154" width, which is narrower. While both are 8-pin SOIC packages, the different widths may require PCB layout verification to confirm footprint compatibility with existing designs.

Q: Do all substitute parts meet the same regulatory and compliance requirements?

A: Yes. TLC272CPS and LM432MA/NOPB both maintain ROHS3 compliance, MSL Level 1 (Unlimited) rating, and REACH Unaffected status, matching the regulatory profile of TLC272CPSG4. All three parts carry the same ECCN (EAR99) and HTSUS (8542.33.0001) classifications.
