Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC252BCP is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-channel amplifier configuration (2 circuits)
• CMOS or general-purpose amplifier technology
• Slew rate within acceptable operational range (2.9 V/µs baseline)
• Gain bandwidth product supporting 2.2 MHz applications
• Input bias current in the picoampere to nanoampere range
• Supply voltage span compatibility (minimum 1.4 V to 2.7 V; maximum 14 V to 16 V)

Package Compatibility Criteria:

• 8-pin DIP package for direct pin-compatible replacement (TLC252BCP, NJM13404D#)
• 8-pin SOIC package for surface-mount alternative (TLV9152IDR)

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required

The TLV9152IDR provides enhanced performance characteristics with rail-to-rail output, higher slew rate, and extended temperature range, suitable for applications requiring improved specifications. The NJM13404D# maintains through-hole DIP packaging identical to the TLC252BCP, offering direct mechanical and electrical compatibility with legacy board designs.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement:

The NJM13404D# is the appropriate substitute when mechanical and electrical pin compatibility with existing through-hole PCB layouts is required. Both the TLC252BCP and NJM13404D# utilize 8-DIP packaging with identical 0.300" (7.62mm) spacing. The NJM13404D# maintains active product status with RoHS compliance, ensuring long-term availability. The supply voltage span (2 V to 14 V) overlaps the TLC252BCP operating range, supporting existing circuit designs. The slew rate of 1.2 V/µs is lower than the TLC252BCP; applications sensitive to slew rate performance require circuit validation.

For Enhanced Performance with Surface-Mount Conversion:

The TLV9152IDR is suitable for new designs or redesigns incorporating surface-mount technology. This device offers superior performance metrics: 20 V/µs slew rate, 4.5 MHz gain bandwidth product, and rail-to-rail output capability. The extended operating temperature range (-40°C to 125°C) accommodates industrial and automotive applications beyond the TLC252BCP specification. The TLV9152IDR requires PCB layout modification due to 8-SOIC packaging; direct pin-for-pin replacement is not possible. Both devices are manufactured by Texas Instruments and maintain ROHS3 compliance.

Compliance and Availability:

Both substitute parts carry active product status, ensuring continued manufacturing and supply chain availability. The NJM13404D# and TLV9152IDR are REACH unaffected and RoHS compliant, meeting regulatory requirements equivalent to the TLC252BCP.

Frequently Asked Questions (FAQ)

Q: Can the TLV9152IDR replace the TLC252BCP in an existing through-hole PCB design?

A: No. The TLV9152IDR uses 8-SOIC surface-mount packaging, while the TLC252BCP uses 8-DIP through-hole packaging. Direct mechanical substitution is not possible without PCB redesign. The NJM13404D# is the appropriate through-hole substitute.

Q: What is the primary difference between the TLC252BCP and NJM13404D# in terms of electrical performance?

A: The NJM13404D# has a lower slew rate (1.2 V/µs versus 2.9 V/µs) and higher input bias current (25 nA versus 0.6 pA). The gain bandwidth product is slightly lower (2 MHz versus 2.2 MHz). Applications requiring high-speed transient response or extremely low input bias current should be evaluated for compatibility.

Q: Are both substitute parts RoHS compliant?

A: Yes. The NJM13404D# is RoHS compliant, and the TLV9152IDR is ROHS3 compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the minimum supply voltage for each part?

A: TLC252BCP: 1.4 V; TLV9152IDR: 2.7 V; NJM13404D#: 2 V. Circuits designed for operation below 2 V require the TLC252BCP or equivalent CMOS technology with lower minimum supply voltage.

Q: Can the TLV9152IDR operate at the same temperature range as the TLC252BCP?

A: The TLV9152IDR operates from -40°C to 125°C, which exceeds the TLC252BCP range of 0°C to 70°C. The TLV9152IDR is suitable for extended temperature applications. The NJM13404D# operates from -40°C to 85°C, also exceeding the TLC252BCP range.

Q: What is the significance of the TLC252BCP "Last Time Buy" status?

A: Last Time Buy indicates that Texas Instruments has announced end-of-life for this product. Existing inventory will be sold until depletion, after which the part will no longer be available. Designers should transition to active substitute parts such as the NJM13404D# or TLV9152IDR for new designs and long-term production requirements.

Q: Is the NJM13404D# a pin-for-pin compatible replacement?

A: Yes. Both the TLC252BCP and NJM13404D# use 8-DIP packaging with identical pin spacing (0.300", 7.62mm). Pin-for-pin compatibility is confirmed. Circuit validation is recommended to confirm performance adequacy for specific application requirements.

Q: What are the output current capabilities of each part?

A: The TLC252BCP does not specify output current per channel. The TLV9152IDR provides 75 mA per channel, and the NJM13404D# provides 35 mA per channel. Applications requiring high output current should use the TLV9152IDR.
