TLC25L2CPSRG4 Equivalent & Substitute Parts

Part Overview

The TLC25L2CPSRG4 is a CMOS amplifier integrated circuit manufactured by Texas Instruments, featuring two independent circuits with single-ended output configuration. This device is classified as a LinCMOS™ series component and is designated as Obsolete product status. The part is housed in an 8-SO surface mount package with a width of 5.30mm.

Due to its Obsolete status, locating original inventory may present supply chain challenges. Identifying equivalent and substitute parts ensures design continuity and project timeline adherence. Substitute components must maintain electrical compatibility across critical parameters including supply voltage range, input bias current, slew rate, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

TLC25L2CDR Selection Criteria:

The TLC25L2CDR represents the primary equivalent substitute for the TLC25L2CPSRG4. Both components share identical electrical specifications across all critical parameters: CMOS amplifier type, 2-circuit configuration, single-ended output, 2.9V/µs slew rate, 110 kHz gain bandwidth product, 0.7 pA input bias current, 1.1 mV input offset voltage, 29µA supply current per channel pair, and 1.4V to 16V supply voltage range. Operating temperature specifications are identical at 0°C to 70°C.

The primary distinction between these parts is packaging format and product lifecycle status. The TLC25L2CDR is supplied in Tape & Reel format with Last Time Buy status, indicating extended availability compared to the Obsolete TLC25L2CPSRG4. Both components comply with ROHS3 requirements, maintain MSL 1 (Unlimited) moisture sensitivity classification, and carry REACH Unaffected designation.

Package geometry differs: TLC25L2CPSRG4 utilizes 8-SOIC with 5.30mm width, while TLC25L2CDR employs 8-SOIC with 3.90mm width. PCB layout and footprint modifications are required for this substitution.

LM432MA/NOPB Selection Criteria:

The LM432MA/NOPB functions as a secondary substitute option when TLC25L2CDR availability is constrained. This General Purpose amplifier maintains the 2-circuit, 8-SOIC package configuration and shares identical maximum supply voltage specification (16V). However, significant electrical parameter deviations exist:

• Minimum supply voltage: 2.5V (versus 1.4V for TLC25L2CPSRG4)
• Input bias current: 3 nanoamperes (versus 0.7 picoamperes)
• Input offset voltage: 600 microvolts (versus 1.1 millivolts)
• Gain bandwidth product: 1 megahertz (versus 110 kilohertz)
• Supply current: 150µA per channel pair (versus 29µA)
• Operating temperature: -40°C to 85°C (versus 0°C to 70°C)

The LM432MA/NOPB is suitable only for applications where the lower gain bandwidth product, higher input bias current, and elevated supply current consumption are acceptable trade-offs. Extended operating temperature range provides advantage in temperature-critical environments.

All three components maintain ROHS3 compliance, MSL 1 classification, and REACH Unaffected status, satisfying regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q1: Can TLC25L2CDR directly replace TLC25L2CPSRG4 without circuit modification?

A: Electrical substitution is direct due to identical specifications. However, package geometry differs (5.30mm versus 3.90mm width in 8-SOIC form factor). PCB footprint redesign is required. Verify land pattern compatibility with your circuit board layout before implementation.

Q2: What are the primary differences between CMOS and General Purpose amplifier classifications?

A: CMOS amplifiers, including the TLC25L2 series, feature ultra-low input bias current (0.7 pA) and minimal input offset voltage (1.1 mV), making them suitable for high-impedance signal sources and precision measurement applications. General Purpose amplifiers like the LM432MA/NOPB exhibit higher input bias current (3 nA) and lower input offset voltage (600 µV), with broader gain bandwidth product (1 MHz). Selection depends on application requirements for input impedance and frequency response.

Q3: Is the LM432MA/NOPB suitable for low-voltage applications requiring 1.4V minimum supply?

A: No. The LM432MA/NOPB specifies 2.5V minimum supply voltage, making it incompatible with applications requiring 1.4V operation. The TLC25L2CDR maintains the 1.4V minimum specification and is the appropriate choice for low-voltage designs.

Q4: How does supply current consumption affect component selection?

A: TLC25L2CPSRG4 and TLC25L2CDR consume 29µA per channel pair, while LM432MA/NOPB consumes 150µA per channel pair. In battery-powered or energy-constrained applications, the CMOS variants provide significant power efficiency advantage. Calculate total system power budget to determine acceptable supply current levels.

Q5: What is the significance of "Last Time Buy" product status for TLC25L2CDR?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this component, with a defined final order date. Inventory remains available but will eventually deplete. For long-term production requirements, secure adequate stock during the Last Time Buy window. The Obsolete status of TLC25L2CPSRG4 indicates production has already ceased.

Q6: Are all three components suitable for industrial temperature range applications?

A: No. TLC25L2CPSRG4 and TLC25L2CDR operate within 0°C to 70°C range, suitable for commercial applications. The LM432MA/NOPB extends to -40°C to 85°C, accommodating industrial and automotive temperature requirements. Select based on your application's thermal environment specifications.

Q7: Do package dimension changes affect thermal performance?

A: The 8-SOIC package format remains constant across all three components. Width variation (5.30mm versus 3.90mm) reflects different manufacturing generations but does not significantly impact thermal characteristics. Thermal performance is primarily determined by die design and package material properties, which remain equivalent between TLC25L2CPSRG4 and TLC25L2CDR.

Q8: What compliance certifications apply to all substitute options?

A: All three components maintain ROHS3 Compliant status, MSL 1 (Unlimited) moisture sensitivity classification, REACH Unaffected designation, and EAR99 export control classification. These certifications satisfy regulatory requirements for commercial and industrial applications in most jurisdictions.
