Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC25L2CPSR is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: CMOS configuration
• Number of Circuits: 2 independent circuits
• Output Type: Single-Ended output
• Slew Rate: 2.9 V/µs
• Gain Bandwidth Product: 110 kHz
• Current - Input Bias: 0.7 pA
• Voltage - Input Offset: 1.1 mV
• Current - Supply: 29 µA (x2 Channels)
• Voltage - Supply Span: 1.4 V (Min) to 16 V (Max)
• Operating Temperature: 0°C to 70°C
• Package / Case: 8-SOIC form factor
• RoHS3 Compliance

Identified Substitute Parts:

1. TLC25L2CDR — Direct functional equivalent with identical electrical specifications. Differs in packaging format (Tape & Reel vs. Tube) and product status (Last Time Buy vs. Obsolete). Maintains all critical electrical parameters and CMOS amplifier architecture.

2. LM432MA/NOPB — General Purpose amplifier with 2 circuits in 8-SOIC package. Presents significant electrical differences including higher Gain Bandwidth Product (1 MHz vs. 110 kHz), higher input bias current (3 nA vs. 0.7 pA), and higher supply current (150 µA vs. 29 µA). Extended operating temperature range (-40°C to 85°C). Suitable only where higher bandwidth and broader temperature operation are acceptable trade-offs.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

TLC25L2CDR is the primary substitute for TLC25L2CPSR. Both components maintain identical electrical specifications across all critical parameters: CMOS amplifier type, 2-circuit configuration, 110 kHz gain bandwidth product, 2.9 V/µs slew rate, and 29 µA supply current. The primary distinction is packaging format (Tape & Reel vs. Tube) and product lifecycle status (Last Time Buy vs. Obsolete). TLC25L2CDR offers extended availability and is suitable for direct pin-compatible replacement in existing designs. Both components are ROHS3 compliant with MSL 1 rating.

For Applications Requiring Extended Temperature Range or Higher Bandwidth:

LM432MA/NOPB presents an alternative where system requirements permit deviation from the original electrical specifications. This substitute operates across -40°C to 85°C (versus 0°C to 70°C for TLC25L2CPSR) and provides 1 MHz gain bandwidth product (versus 110 kHz). However, LM432MA/NOPB exhibits higher supply current consumption (150 µA vs. 29 µA), higher input bias current (3 nA vs. 0.7 pA), and higher minimum supply voltage requirement (2.5 V vs. 1.4 V). Selection of LM432MA/NOPB requires circuit redesign validation to confirm compatibility with these electrical differences.

Compliance Considerations:

All identified substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. REACH status is unaffected for all components.

Frequently Asked Questions (FAQ)

Q: Can TLC25L2CDR be used as a direct replacement for TLC25L2CPSR?

A: Yes. TLC25L2CDR is electrically identical to TLC25L2CPSR across all specified parameters. Both are CMOS amplifiers with 2 circuits, 110 kHz gain bandwidth product, 2.9 V/µs slew rate, and 29 µA supply current. The primary difference is packaging format (Tape & Reel vs. Tube). Pin configuration and electrical performance are equivalent, enabling direct substitution without circuit modification.

Q: What are the package differences between TLC25L2CPSR and TLC25L2CDR?

A: TLC25L2CPSR uses 8-SOIC packaging with 0.209" (5.30mm) width, while TLC25L2CDR uses 8-SOIC packaging with 0.154" (3.90mm) width. Both are surface-mount 8-pin SOIC packages with identical pin assignments. The dimensional difference reflects manufacturing process evolution. PCB layout compatibility depends on specific footprint design; verification of pad spacing is required.

Q: Why is LM432MA/NOPB listed as a substitute if it has different electrical specifications?

A: LM432MA/NOPB is identified as a substitute option for applications where the extended operating temperature range (-40°C to 85°C) and higher gain bandwidth product (1 MHz) are beneficial. However, this component exhibits higher power consumption and different input characteristics. Selection requires validation that the application can tolerate these electrical differences. LM432MA/NOPB is not a direct replacement and should not be used without circuit analysis.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC25L2CDR and LM432MA/NOPB are both ROHS3 compliant, matching the compliance status of TLC25L2CPSR. All components carry MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Last Time Buy status indicates that TLC25L2CDR has limited remaining availability from the manufacturer. This component will eventually reach end-of-life. While currently available in higher inventory (5100 pcs) compared to TLC25L2CPSR (1194 pcs), procurement planning should account for eventual discontinuation. For long-term production requirements, evaluation of alternative architectures may be necessary.

Q: Can I use LM432MA/NOPB in a low-power application designed for TLC25L2CPSR?

A: LM432MA/NOPB is not suitable for low-power applications without circuit redesign. The supply current is 150 µA (x2 channels) compared to 29 µA for TLC25L2CPSR, representing a 5.2x increase in power consumption. Additionally, the minimum supply voltage is 2.5 V versus 1.4 V, which may be incompatible with ultra-low-voltage designs. Substitution requires full system power budget recalculation.
