TLC252CP Equivalent & Substitute Parts

Part Overview

The TLC252CP is a CMOS dual-channel operational amplifier manufactured by Texas Instruments in 8-DIP through-hole packaging. This device operates as a general-purpose linear amplifier with low input bias current and operates across a 1.4V to 16V supply voltage range. The TLC252CP is designated as Last Time Buy, indicating discontinued production status. Identification of equivalent and substitute parts is necessary to ensure design continuity and procurement availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC252CP is determined by the following critical parameters: dual-channel amplifier configuration, through-hole or surface-mount packaging compatibility, supply voltage range overlap, operating temperature range, and regulatory compliance status. The TLC252CP operates with a minimum supply voltage of 1.4V and maximum of 16V, establishing the lower and upper bounds for acceptable substitutes.

Two substitute parts are identified based on functional equivalence:

TLV9152IDR (Texas Instruments): Maintains dual-channel amplifier architecture with expanded operating temperature range (-40°C to 125°C) and active product status. This substitute operates across 2.7V to 16V supply range, overlapping the TLC252CP maximum specification. Packaging differs as surface-mount 8-SOIC, requiring PCB redesign for through-hole applications.

NJM13404D# (Nisshinbo Micro Devices Inc.): Maintains dual-channel amplifier architecture in identical 8-DIP through-hole packaging (0.300", 7.62mm). This substitute operates across 2V to 14V supply range, overlapping the TLC252CP specification band. Operating temperature range extends to -40°C to 85°C with active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: The NJM13404D# is the appropriate substitute when PCB layout and mechanical mounting constraints require through-hole packaging identical to the TLC252CP. Both devices utilize 8-DIP (0.300", 7.62mm) packaging. The NJM13404D# maintains active product status and RoHS compliance. Supply voltage compatibility exists within the 2V to 14V range, which overlaps the TLC252CP operating band. The operating temperature range of -40°C to 85°C extends below the TLC252CP specification minimum of 0°C, providing broader environmental coverage.

For Surface-Mount Applications or Enhanced Performance: The TLV9152IDR is suitable when PCB redesign to surface-mount technology is feasible. This substitute offers superior performance characteristics including higher slew rate (20V/µs versus 2.9V/µs), increased gain bandwidth product (4.5MHz versus 2.2MHz), and lower input offset voltage (125µV versus 1.1mV). The TLV9152IDR maintains active product status, ROHS3 compliance, and operates across -40°C to 125°C, extending the operating temperature envelope. Supply voltage compatibility exists within the 2.7V to 16V range.

Regulatory and Compliance Considerations: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the TLC252CP. Both are classified under ECCN EAR99 and HTSUS 8542.33.0001, matching the original part classification.

Frequently Asked Questions (FAQ)

Q: Can the TLV9152IDR directly replace the TLC252CP on existing PCBs?

A: No. The TLV9152IDR uses 8-SOIC surface-mount packaging (0.154", 3.90mm width) while the TLC252CP uses 8-DIP through-hole packaging (0.300", 7.62mm). PCB redesign and rework are required for this substitution.

Q: What is the minimum supply voltage requirement for each substitute?

A: The TLC252CP operates at 1.4V minimum. The NJM13404D# operates at 2V minimum, and the TLV9152IDR operates at 2.7V minimum. Applications requiring operation below 2V cannot use either substitute without circuit modification.

Q: Does the NJM13404D# maintain identical pin configuration to the TLC252CP?

A: Both devices use 8-DIP packaging with 0.300" (7.62mm) spacing. Pin configuration compatibility must be verified against device datasheets for specific application circuits.

Q: What are the key performance differences between substitutes?

A: The TLV9152IDR provides higher slew rate (20V/µs versus 2.9V/µs for TLC252CP and 1.2V/µs for NJM13404D#) and higher gain bandwidth product (4.5MHz versus 2.2MHz for TLC252CP and 2MHz for NJM13404D#). The NJM13404D# provides lower input bias current (25nA versus 0.6pA for TLC252CP and 10pA for TLV9152IDR).

Q: Are both substitutes suitable for low-voltage applications?

A: The NJM13404D# supports operation down to 2V supply voltage. The TLV9152IDR requires minimum 2.7V. Applications requiring 1.4V to 2V operation cannot use either substitute.

Q: What is the inventory status of substitute parts?

A: TLV9152IDR has 15,900 pieces in stock. NJM13404D# has 776 pieces in stock. Both are active products with ongoing availability.

Q: Do the substitutes maintain RoHS compliance?

A: Yes. Both TLV9152IDR and NJM13404D# are RoHS compliant. TLV9152IDR is ROHS3 compliant. NJM13404D# is RoHS compliant.
