TLC27M7CPSR Equivalent & Substitute Parts

Part Overview

The TLC27M7CPSR is a CMOS linear amplifier integrated circuit manufactured by Texas Instruments, featuring two independent amplifier circuits in an 8-SO surface mount package. This device is classified as a Last Time Buy product, indicating that it is no longer in active production and existing inventory represents the final availability from the manufacturer.

The necessity to identify equivalent and substitute parts arises from the Last Time Buy status of the TLC27M7CPSR. Design engineers and procurement specialists must evaluate alternative components to ensure long-term supply chain continuity and support for ongoing production requirements. Substitute parts must maintain electrical compatibility across critical performance parameters while accommodating potential packaging and operational differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC27M7CPSR is determined by strict alignment with the following electrical and mechanical parameters:

Critical Substitution 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: 190 µV
• Current - Supply: 285 µA (x2 Channels)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 3 V to 16 V
• Operating Temperature: 0°C to 70°C
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain identical electrical performance across all specified parameters. Packaging variations are permissible when the physical form factor accommodates the application's PCB layout and assembly process requirements. The base product number TLC27M7 identifies the core electrical specification family.

Engineering Selection Recommendations

TLC27M7CDR (Manufacturer Recommended Primary Substitute)

The TLC27M7CDR is the manufacturer-recommended substitute for the TLC27M7CPSR. This part maintains identical electrical specifications across all critical parameters: CMOS amplifier type, dual-circuit configuration, 0.62 V/µs slew rate, 635 kHz gain bandwidth product, 0.7 pA input bias current, 190 µV input offset voltage, 285 µA supply current, and 30 mA output current per channel. The operating temperature range (0°C to 70°C) and supply voltage span (3 V to 16 V) are identical.

The primary distinction is packaging format: the TLC27M7CDR is supplied in Cut Tape (CT) format rather than Tape & Reel (TR), and features a narrower 8-SOIC package body width (3.90mm versus 5.30mm). The TLC27M7CDR maintains Active product status, ensuring ongoing availability and manufacturing support. Both parts are ROHS3 compliant with MSL 1 rating.

LM432MA/NOPB (Secondary Substitute with Operational Differences)

The LM432MA/NOPB is a Texas Instruments general-purpose amplifier with dual-circuit configuration and identical output current capability (30 mA per channel). This part exhibits higher gain bandwidth product (1 MHz versus 635 kHz), lower input bias current (3 nA versus 0.7 pA), higher input offset voltage (600 µV versus 190 µV), and lower supply current (150 µA versus 285 µA). The operating temperature range extends to -40°C to 85°C, and minimum supply voltage is reduced to 2.5 V.

The LM432MA/NOPB carries Obsolete product status, indicating discontinued manufacturing. This part is suitable only for applications where existing inventory is available and long-term supply is not required. The general-purpose amplifier classification and performance parameter variations necessitate circuit-level evaluation before implementation.

Frequently Asked Questions (FAQ)

Q: Can the TLC27M7CDR directly replace the TLC27M7CPSR in existing designs?

A: The TLC27M7CDR maintains identical electrical specifications and is electrically interchangeable. The primary consideration is packaging format: the TLC27M7CDR uses Cut Tape (CT) delivery and features a narrower 8-SOIC body (3.90mm width versus 5.30mm). PCB layout and assembly equipment compatibility must be verified for the narrower package body width.

Q: What is the significance of the package body width difference between TLC27M7CPSR and TLC27M7CDR?

A: Both parts use 8-SOIC surface mount packages, but the TLC27M7CPSR has a 5.30mm body width while the TLC27M7CDR has a 3.90mm body width. This difference affects PCB footprint spacing and may require layout modifications. Pin pitch and electrical connections remain compatible.

Q: Is the LM432MA/NOPB suitable as a substitute for new production designs?

A: The LM432MA/NOPB is classified as Obsolete and is not recommended for new production designs. While electrically similar in circuit count and output capability, the performance parameters differ significantly (higher gain bandwidth product, lower input bias current, higher input offset voltage, lower supply current). Additionally, Obsolete status indicates no ongoing manufacturing support.

Q: What are the key electrical differences between the TLC27M7CPSR and LM432MA/NOPB?

A: The LM432MA/NOPB exhibits higher gain bandwidth product (1 MHz versus 635 kHz), lower input bias current (3 nA versus 0.7 pA), higher input offset voltage (600 µV versus 190 µV), and lower supply current consumption (150 µA versus 285 µA). These differences may affect circuit performance in precision applications requiring low input offset voltage or low input bias current.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the TLC27M7CDR and LM432MA/NOPB are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the TLC27M7CPSR.

Q: What packaging options are available for the TLC27M7 base product?

A: The TLC27M7CPSR is supplied in Tape & Reel (TR) format, while the TLC27M7CDR is supplied in Cut Tape (CT) format. The LM432MA/NOPB is supplied in Tube format. Selection depends on production volume requirements and assembly process specifications.

Q: Can the TLC27M7CDR be used in applications requiring extended temperature operation?

A: The TLC27M7CDR maintains the same operating temperature range as the TLC27M7CPSR (0°C to 70°C). For applications requiring extended temperature operation, the LM432MA/NOPB supports -40°C to 85°C; however, this part is Obsolete and exhibits different electrical characteristics.
