TLV2342IP Equivalent & Substitute Parts

Part Overview

The TLV2342IP is a CMOS amplifier integrated circuit manufactured by Texas Instruments, configured as a 2-circuit operational amplifier in an 8-pin DIP package. This device is classified as a LinCMOS™ series component and is currently designated as Last Time Buy, indicating that the manufacturer has announced end-of-life status. The TLV2342IP is designed for applications requiring low-power CMOS amplification with dual-channel configuration in through-hole mounting format.

Identification of equivalent and substitute parts becomes necessary due to the Last Time Buy status of the TLV2342IP. Engineers and procurement specialists require alternative components that maintain functional compatibility while ensuring continued availability and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2342IP requires evaluation based on the following critical parameters that define functional and mechanical compatibility:

Functional Parameters:

• Number of circuits (must equal 2)
• Amplifier classification (CMOS or General Purpose)
• Slew rate (minimum acceptable performance)
• Gain bandwidth product (frequency response capability)
• Input bias current (signal integrity)
• Input offset voltage (DC accuracy)
• Supply current (power consumption)
• Output current per channel (load driving capability)
• Supply voltage range (operating envelope)
• Operating temperature range (thermal compatibility)

Mechanical Parameters:

• Mounting type (through-hole vs. surface mount)
• Package configuration (DIP vs. SOIC)
• Physical dimensions and pin compatibility

Compliance Parameters:

• RoHS status
• REACH compliance
• Product status (active vs. end-of-life)

The TLV9102IDR is identified as a manufacturer-recommended substitute. This device maintains the dual-circuit configuration and operates within compatible supply voltage ranges, though it employs surface-mount packaging and exhibits different electrical characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TLV2342IP carries Last Time Buy designation, confirming manufacturer end-of-life status. The TLV9102IDR maintains Active product status, ensuring long-term availability and continued manufacturing support from Texas Instruments.

Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in compliant applications.

Electrical Performance Trade-offs: The TLV9102IDR demonstrates superior slew rate performance (4.5 V/µs vs. 3.6 V/µs) and enhanced output current capability (80 mA vs. 30 mA per channel). However, the TLV9102IDR exhibits lower gain bandwidth product (1.1 MHz vs. 1.7 MHz) and higher input bias current (10 pA vs. 0.6 pA). The TLV9102IDR provides superior input offset voltage accuracy (0.3 mV vs. 1.1 mV) and significantly reduced supply current consumption (0.115 mA vs. 1.4 mA for dual channels).

Packaging and Mounting Implications: The TLV2342IP utilizes through-hole 8-DIP packaging, while the TLV9102IDR employs surface-mount 8-SOIC configuration. This difference requires PCB redesign and assembly process modification. The TLV9102IDR occupies reduced board space (3.90mm width vs. 7.62mm width).

Supply Voltage Range: The TLV9102IDR supports extended maximum supply voltage (16 V vs. 8 V) and higher minimum supply voltage (2.7 V vs. 2 V). Applications operating at the TLV2342IP minimum supply voltage of 2 V require verification against TLV9102IDR minimum specification of 2.7 V.

Temperature Range: The TLV9102IDR extends maximum operating temperature to 125°C compared to the TLV2342IP specification of 85°C, providing enhanced thermal margin for high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the TLV9102IDR directly replace the TLV2342IP without PCB modification?

A: No. The TLV2342IP uses through-hole 8-DIP packaging while the TLV9102IDR uses surface-mount 8-SOIC packaging. PCB redesign is required to accommodate the different package footprint and mounting technology.

Q: What are the critical electrical differences between these devices?

A: Key differences include: (1) Gain bandwidth product is lower in the TLV9102IDR (1.1 MHz vs. 1.7 MHz); (2) Supply current is significantly lower in the TLV9102IDR (0.115 mA vs. 1.4 mA); (3) Output current capability is higher in the TLV9102IDR (80 mA vs. 30 mA); (4) Input bias current is higher in the TLV9102IDR (10 pA vs. 0.6 pA); (5) Minimum supply voltage is higher in the TLV9102IDR (2.7 V vs. 2 V).

Q: Is the TLV9102IDR suitable for applications requiring operation at 2 V supply voltage?

A: No. The TLV9102IDR minimum supply voltage specification is 2.7 V. Applications requiring 2 V operation must verify alternative substitutes or confirm that the TLV2342IP can be procured through remaining inventory channels.

Q: What compliance certifications apply to both devices?

A: Both the TLV2342IP and TLV9102IDR maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in compliant applications.

Q: How does the extended temperature range of the TLV9102IDR affect substitution decisions?

A: The TLV9102IDR operates to 125°C maximum temperature compared to the TLV2342IP specification of 85°C. This extended range provides additional thermal margin but does not restrict substitution in applications operating within the TLV2342IP temperature envelope of -40°C to 85°C.

Q: What is the significance of the rail-to-rail output specification on the TLV9102IDR?

A: Rail-to-rail output capability indicates the TLV9102IDR output voltage can swing to the positive and negative supply rails. The TLV2342IP does not specify this characteristic. This difference may affect signal amplitude in applications requiring maximum output voltage swing.

Q: Are there inventory considerations for the TLV2342IP?

A: The TLV2342IP is designated Last Time Buy with 3,486 pieces reported in stock. The TLV9102IDR maintains Active status with 125,096 pieces in inventory, providing significantly greater long-term availability assurance.
