TLE2142CPWR Equivalent & Substitute Parts

Part Overview

The TLE2142CPWR is a general-purpose operational amplifier featuring dual circuits with rail-to-rail output capability, manufactured by Texas Instruments in a 16-TSSOP surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TLE2142CPWR operates across a wide supply voltage range of 4V to 44V and is suitable for applications requiring low input offset voltage and moderate slew rate performance. Due to its Last Time Buy status, identifying compatible substitute parts is essential for design continuity and long-term component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2142CPWR is determined by electrical and functional equivalence across core performance parameters. The primary substitute identified is the TLE2142CDR, which maintains identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. Both parts are manufactured by Texas Instruments and share the same base product number (TLE2142), confirming functional equivalence at the circuit level.

The key parameters governing substitution are:

• Dual-circuit general-purpose amplifier topology
• Rail-to-rail output configuration
• Slew rate of 45V/µs
• Gain bandwidth product of 5.9 MHz
• Input bias current of 700 nA
• Input offset voltage of 290 µV
• Supply current of 6.9 mA per dual channels
• Output current of 50 mA per channel
• Supply voltage range of 4V to 44V
• Operating temperature range of 0°C to 70°C

The primary difference between the main part and substitute is the package format: the TLE2142CPWR uses 16-TSSOP packaging, while the TLE2142CDR uses 8-SOIC packaging. This distinction affects board layout and footprint design but does not alter electrical performance or functional capability.

Parameter Comparison

Engineering Selection Recommendations

The TLE2142CDR serves as the direct electrical equivalent to the TLE2142CPWR with identical performance specifications across all functional parameters. Selection between these parts is determined by packaging requirements and product lifecycle status.

TLE2142CPWR Selection Criteria:

• Existing designs with 16-TSSOP footprint compatibility
• Last Time Buy status requires immediate procurement for legacy system support
• Current inventory of 6,240 pieces available

TLE2142CDR Selection Criteria:

• New designs requiring surface mount general-purpose dual amplifiers
• Active product status ensures long-term availability and supply continuity
• 8-SOIC package format for compact board layouts
• Current inventory of 15,440 pieces available
• Recommended for designs requiring sustained component sourcing beyond Last Time Buy windows

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The electrical equivalence permits direct functional substitution where package footprint modifications are feasible.

Frequently Asked Questions (FAQ)

Q: Can the TLE2142CDR replace the TLE2142CPWR in existing designs?

A: Electrical substitution is complete. The TLE2142CDR maintains identical performance across all specified parameters. Physical substitution requires PCB layout modification due to package format differences: 16-TSSOP versus 8-SOIC. Pin configuration and functional mapping must be verified against the respective datasheets before implementation.

Q: What is the significance of the Last Time Buy status for the TLE2142CPWR?

A: Last Time Buy indicates Texas Instruments has discontinued production of this part number. Existing inventory is limited to 6,240 pieces. For applications requiring long-term component availability, the TLE2142CDR (Active status) is the recommended alternative, with 15,440 pieces currently in stock.

Q: Are there electrical performance differences between the 16-TSSOP and 8-SOIC packages?

A: No. Both packages contain identical die and deliver identical electrical performance. The package difference affects only physical dimensions, board layout, and thermal characteristics. Electrical specifications including slew rate, bandwidth, bias current, and supply voltage range are unchanged.

Q: What compliance certifications apply to both parts?

A: Both the TLE2142CPWR and TLE2142CDR are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited moisture sensitivity). Both carry ECCN EAR99 classification and HTSUS code 8542.33.0001.

Q: Can I use the TLE2142CDR in a design originally specified for the TLE2142CPWR?

A: Functional substitution is valid. Circuit performance will be identical. Physical implementation requires PCB redesign to accommodate the 8-SOIC footprint. Pin-to-pin functional mapping must be confirmed with the device datasheets to ensure correct signal routing and power distribution.

Q: What is the difference in supply current between the two parts?

A: Supply current is identical at 6.9 mA for both dual channels. Power consumption and thermal dissipation characteristics are equivalent across both package formats.
