TL054ID Equivalent & Substitute Parts

Part Overview

The TL054ID is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a 4-circuit linear amplifier in a 14-SOIC surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The TL054ID belongs to the LinCMOS™ series and is ROHS3 compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL054ID is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 operational amplifiers per package
• Package / Case: 14-SOIC surface mount form factor
• Electrical Performance: Slew Rate, Gain Bandwidth Product, Input Bias Current, Input Offset Voltage
• Power Supply Requirements: Voltage span compatibility (10 V to 30 V minimum)
• Output Current Capability: 80 mA per channel minimum
• Compliance: ROHS3 and REACH requirements

Substitute parts are grouped into two categories based on product status and packaging format:

Category 1: Active Status Substitutes - Parts with active manufacturing status and current availability Category 2: Last Time Buy / Obsolete Status Substitutes - Parts with limited procurement windows

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TL054IDR

The TL054IDR is the manufacturer-recommended direct substitute for the TL054ID. This part maintains identical electrical specifications across all critical parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capability. The TL054IDR is in active production status with current inventory availability (1310 pcs), ensuring long-term procurement viability. Packaging format differs only in tape & reel presentation (Cut Tape & Digi-Reel®) versus tube packaging, with identical 14-SOIC form factor dimensions (0.154", 3.90mm width). Both parts are ROHS3 compliant and REACH unaffected.

Secondary Recommendation: TL054CNSR

The TL054CNSR provides electrical equivalence to the TL054ID with identical performance specifications. This part carries Last Time Buy status, indicating a defined procurement window before discontinuation. The operating temperature range is narrower (0°C to 70°C versus -40°C to 85°C), which may restrict use in extended temperature applications. Package dimensions differ slightly (0.209", 5.30mm width versus 0.154", 3.90mm width), requiring PCB layout verification. Inventory availability is limited (1148 pcs). This substitute is suitable only for applications within the specified temperature range and where PCB footprint accommodation is feasible.

Alternative Consideration: LF247DT

The LF247DT from STMicroelectronics offers J-FET amplifier functionality in a 4-circuit configuration with 14-SOIC packaging. This part exhibits performance variations that require application-level evaluation: higher gain bandwidth product (4 MHz versus 2.7 MHz), lower input bias current (20 pA versus 30 pA), higher input offset voltage (3 mV versus 560 µV), and reduced output current per channel (40 mA versus 80 mA). The supply voltage requirement is fixed at 44 V, incompatible with the TL054ID's 10 V to 30 V range. The LF247DT is active production with substantial inventory (17352 pcs) and extended operating temperature range (-40°C to 105°C). This part is suitable only for applications where the electrical parameter differences and fixed supply voltage are acceptable.

Frequently Asked Questions (FAQ)

Q: Can TL054IDR be used as a direct replacement for TL054ID in existing designs?

A: Yes. The TL054IDR maintains identical electrical specifications and 14-SOIC package dimensions. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube). No circuit modifications are required.

Q: What is the key difference between TL054IDR and TL054CNSR?

A: Both parts are electrically equivalent to TL054ID. TL054IDR is in active production with full temperature range (-40°C to 85°C), while TL054CNSR is Last Time Buy status with narrower temperature range (0°C to 70°C) and slightly different package width (0.209" versus 0.154"). Select TL054IDR for new designs and long-term availability.

Q: Is LF247DT a suitable substitute for TL054ID?

A: LF247DT is not a direct substitute. While both are J-FET 4-circuit amplifiers in 14-SOIC packages, LF247DT has different electrical specifications: higher bandwidth (4 MHz), lower output current (40 mA versus 80 mA), higher input offset voltage (3 mV versus 560 µV), and fixed 44 V supply voltage incompatible with TL054ID's 10 V to 30 V range. Use LF247DT only if application requirements align with these parameter differences.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TL054IDR, TL054CNSR, and LF247DT are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the TL054ID compliance profile.

Q: What is the inventory status for each substitute?

A: TL054IDR has 1310 pcs available (active status). TL054CNSR has 1148 pcs available (Last Time Buy status). LF247DT has 17352 pcs available (active status). For long-term procurement, TL054IDR is recommended.

Q: Can TL054CNSR be used in applications requiring -40°C operation?

A: No. TL054CNSR operating temperature range is 0°C to 70°C. Applications requiring -40°C operation must use TL054IDR or LF247DT.

Q: What are the package dimension differences between substitutes?

A: TL054ID and TL054IDR both use 14-SOIC with 0.154" (3.90mm) width. TL054CNSR uses 14-SOIC with 0.209" (5.30mm) width, requiring PCB footprint verification. LF247DT uses 14-SOIC with 0.154" (3.90mm) width, matching TL054ID dimensions.
