TLV2342ID Equivalent & Substitute Parts

Part Overview

The TLV2342ID is a CMOS amplifier integrated circuit manufactured by Texas Instruments, configured as a dual-channel operational amplifier in an 8-SOIC surface mount package. This device is classified as a LinCMOS™ series component and is designated as Last Time Buy status, indicating discontinued production with limited inventory availability.

The TLV2342ID is necessary to identify equivalent substitute parts due to its Last Time Buy status. Organizations requiring this functionality for new designs or ongoing production must evaluate alternative components that maintain electrical and mechanical compatibility within the specified parameter ranges.

• Package dimensions: 0.154" width (3.90mm)
• Mounting type: Surface mount

Electrical Compatibility Parameters:

• Dual-channel configuration (2 circuits minimum)
• Supply voltage range: Minimum 2V, Maximum 8V (substitute must accommodate this range)
• Output current capability: Minimum 30 mA per channel
• Input bias current: Maximum 0.6 pA (lower values acceptable)
• Input offset voltage: Maximum 1.1 mV (lower values acceptable)
• Supply current: Maximum 1.4 mA for dual channels
• Slew rate: Minimum 3.6 V/µs
• Gain bandwidth product: Minimum 1.7 MHz
• Operating temperature range: -40°C to 85°C minimum

Compliance Requirements:

• RoHS3 compliance
• Moisture sensitivity level 1 or better
• REACH unaffected status

The TLV9102IDR meets these substitution criteria and is identified as the manufacturer-recommended equivalent.

Engineering Selection Recommendations

TLV9102IDR as Substitute for TLV2342ID:

The TLV9102IDR is qualified as a direct substitute based on the following engineering criteria:

Mechanical Compatibility: Both devices utilize identical 8-SOIC surface mount packaging with matching 0.154" (3.90mm) width dimensions, ensuring PCB layout compatibility without redesign.

Electrical Compatibility: The TLV9102IDR operates within the TLV2342ID supply voltage range of 2V to 8V (TLV9102IDR supports extended range to 16V). All critical electrical parameters meet or exceed TLV2342ID specifications: output current per channel (80 mA vs. 30 mA), slew rate (4.5 V/µs vs. 3.6 V/µs), and input offset voltage (0.3 mV vs. 1.1 mV).

Compliance Status: Both components maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.

Product Availability: The TLV9102IDR maintains Active product status with substantial inventory availability (125,096 pieces), addressing the supply constraint created by the TLV2342ID Last Time Buy designation.

Temperature Operating Range: The TLV9102IDR extends the upper operating temperature limit to 125°C, providing enhanced thermal margin beyond the TLV2342ID specification of 85°C.

Frequently Asked Questions (FAQ)

Q: Can the TLV9102IDR directly replace the TLV2342ID without PCB modifications?

A: Yes. Both devices share identical 8-SOIC packaging dimensions and surface mount configuration. Pin-to-pin compatibility is maintained, allowing direct substitution without PCB layout changes.

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

A: The TLV9102IDR provides superior performance in several parameters: higher slew rate (4.5 V/µs vs. 3.6 V/µs), lower input offset voltage (0.3 mV vs. 1.1 mV), higher output current capability (80 mA vs. 30 mA per channel), and significantly lower supply current (0.115 mA vs. 1.4 mA for dual channels). The TLV2342ID offers higher gain bandwidth product (1.7 MHz vs. 1.1 MHz) and lower input bias current (0.6 pA vs. 10 pA).

Q: Does the TLV9102IDR support the same supply voltage range as the TLV2342ID?

A: The TLV9102IDR supports the complete TLV2342ID supply range of 2V to 8V, with extended capability to 16V maximum. Applications designed for 2V to 8V operation are fully compatible.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both devices maintain identical RoHS3 compliance, MSL Level 1 moisture sensitivity rating, and REACH unaffected status. Substitution does not introduce regulatory compliance issues.

Q: Why is the TLV2342ID designated as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this device. The TLV9102IDR represents the active product line replacement, maintaining functional equivalence while providing enhanced specifications and continued availability.

Q: What is the primary advantage of substituting to the TLV9102IDR?

A: The primary advantage is sustained component availability. The TLV9102IDR maintains Active product status with high inventory levels, eliminating supply chain risk associated with the TLV2342ID Last Time Buy status. Secondary advantages include improved electrical performance characteristics and extended operating temperature range.

Q: Are there applications where the TLV2342ID cannot be substituted with the TLV9102IDR?

A: Substitution is valid for all applications within the specified electrical and thermal operating ranges. The TLV9102IDR's superior performance characteristics ensure compatibility with designs originally specified for the TLV2342ID.
