TLC25M2CP Equivalent & Substitute Parts Reference

Part Overview

The TLC25M2CP is a CMOS amplifier integrated circuit manufactured by Texas Instruments, featuring 2 circuits in an 8-DIP through-hole package with open drain output configuration. This device operates across a wide supply voltage range of 1.4V to 16V and is designed for applications requiring low input bias current and low input offset voltage characteristics.

The TLC25M2CP carries a Last Time Buy product status, indicating that Texas Instruments has discontinued this part number. This status necessitates identification of equivalent and substitute components to maintain design continuity and ensure long-term supply chain reliability for applications currently utilizing this device.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC25M2CP is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of circuits: 2 (both substitutes maintain this requirement)
• Input bias current: 0.7 pA (CMOS technology requirement)
• Input offset voltage: 1.1 mV (precision specification)
• Supply current per channel: 285 µA (power consumption profile)
• Supply voltage range overlap: Minimum 1.4V to 16V maximum
• Operating temperature range: 0°C to 70°C
• RoHS3 compliance and REACH unaffected status

Secondary Compatibility Considerations:

• Mounting type (through hole vs. surface mount affects PCB integration)
• Package footprint (8-DIP vs. 8-SOIC affects board layout)
• Output type configuration (open drain vs. standard output)
• Slew rate and gain bandwidth product (application-dependent performance metrics)

The two identified substitutes represent different trade-offs in packaging technology and performance characteristics while maintaining core electrical compatibility within the specified parameter ranges.

Engineering Selection Recommendations

TLC27M2CDR Selection Criteria:

The TLC27M2CDR is the manufacturer-recommended substitute from Texas Instruments, maintaining identical CMOS architecture, input bias current (0.7 pA), input offset voltage (1.1 mV), and supply current per channel (285 µA). This part is currently in Active product status with 55,100 units in stock, ensuring long-term availability.

The primary design consideration is the transition from through-hole (8-DIP) to surface-mount (8-SOIC) packaging. This substitution requires PCB redesign for the component footprint. The TLC27M2CDR exhibits reduced slew rate (0.62 V/µs vs. 2.9 V/µs) and lower gain bandwidth product (635 kHz vs. 1.7 MHz), which may impact applications requiring higher frequency response. The minimum supply voltage requirement increases from 1.4V to 3V, restricting operation in ultra-low voltage applications.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

NJM13404D# Selection Criteria:

The NJM13404D# is a general-purpose amplifier substitute manufactured by Nisshinbo Micro Devices Inc., maintaining the through-hole 8-DIP package format and eliminating PCB redesign requirements. This part is currently in Active product status with 776 units in stock.

This substitute differs significantly in amplifier architecture (general purpose vs. CMOS) and electrical characteristics. Input bias current increases to 25 nA (from 0.7 pA), and supply current per channel increases to 1 mA (from 285 µA), resulting in substantially higher power consumption. The minimum supply voltage requirement is 2V (vs. 1.4V), and maximum operating temperature extends to 85°C (vs. 70°C).

The NJM13404D# offers superior input offset voltage (500 µV vs. 1.1 mV) and higher gain bandwidth product (2 MHz vs. 1.7 MHz). Selection of this substitute is appropriate for applications where through-hole packaging is mandatory and where the increased input bias current and supply current are acceptable trade-offs.

Frequently Asked Questions (FAQ)

Q: Can the TLC27M2CDR directly replace the TLC25M2CP without circuit modifications?

A: The TLC27M2CDR maintains electrical compatibility in terms of input bias current, input offset voltage, and supply current per channel. However, the package transition from 8-DIP (through-hole) to 8-SOIC (surface-mount) requires PCB redesign. Additionally, the reduced slew rate (0.62 V/µs vs. 2.9 V/µs) and lower gain bandwidth product (635 kHz vs. 1.7 MHz) may require circuit validation for frequency-dependent applications. The increased minimum supply voltage (3V vs. 1.4V) eliminates compatibility with ultra-low voltage designs.

Q: What are the key differences between the TLC25M2CP and NJM13404D#?

A: Both devices maintain 2-circuit configuration and 8-DIP through-hole packaging. The NJM13404D# is a general-purpose amplifier with significantly higher input bias current (25 nA vs. 0.7 pA) and supply current per channel (1 mA vs. 285 µA). The NJM13404D# provides superior input offset voltage (500 µV vs. 1.1 mV) and higher gain bandwidth product (2 MHz vs. 1.7 MHz). Operating temperature range extends to -40°C to 85°C. These differences make the NJM13404D# suitable for applications where increased power consumption is acceptable and precision input characteristics are prioritized.

Q: Which substitute is recommended for new designs?

A: Selection depends on packaging requirements and performance priorities. For surface-mount designs, the TLC27M2CDR is the manufacturer-recommended substitute with active product status and high inventory availability. For through-hole designs, the NJM13404D# maintains package compatibility, though with different electrical characteristics. Both parts carry appropriate compliance certifications (ROHS3 and RoHS, respectively) and REACH unaffected status.

Q: Are there supply voltage compatibility issues with either substitute?

A: The TLC27M2CDR requires minimum 3V supply (vs. 1.4V for TLC25M2CP), eliminating compatibility with designs operating below 3V. The NJM13404D# requires minimum 2V supply, also restricting ultra-low voltage applications. Both substitutes maintain the 16V and 14V maximum supply limits respectively, ensuring compatibility with standard supply ranges.

Q: What is the inventory status for each substitute?

A: The TLC27M2CDR has 55,100 units in stock (cut tape and digi-reel packaging). The NJM13404D# has 776 units in stock (tube packaging). The TLC25M2CP has 2,070 units remaining as Last Time Buy inventory. Long-term design transitions should prioritize the TLC27M2CDR due to superior availability and active product status.
