Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2074ACNG4 is determined by the following critical parameters: amplifier type (J-FET input architecture), number of circuits (4-channel configuration), package format (14-DIP through-hole), supply voltage range compatibility, slew rate, gain bandwidth product, input bias current, and input offset voltage specifications.

Primary Substitute (Direct Replacement): TLE2074ACN represents the active production equivalent of TLE2074ACNG4. Both parts share identical electrical specifications, J-FET amplifier topology, 4-circuit configuration, and 14-DIP packaging. The distinction lies in product status (active versus obsolete) and packaging format (tube versus tape-and-reel).

Secondary Substitutes (Functional Alternatives): LT1058CN#PBF and LT1356CN#PBF are functional alternatives that satisfy specific application requirements but introduce parameter trade-offs. These parts maintain J-FET input characteristics and 14-DIP packaging but differ in circuit count, slew rate, bandwidth, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

TLE2074ACN is the recommended primary substitute for TLE2074ACNG4. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. Electrical specifications are identical across all critical parameters: J-FET amplifier topology, 4-circuit configuration, 45 V/µs slew rate, 10 MHz gain bandwidth product, 1 pA input bias current, and 4.5 V to 38 V supply voltage range. The only distinction is packaging format (tube versus tape-and-reel), which does not affect electrical performance. Both parts are ROHS3 compliant and REACH unaffected.

LT1058CN#PBF serves as a secondary substitute when supply constraints or design flexibility permit acceptance of reduced performance specifications. This part maintains J-FET input architecture and 4-circuit configuration in 14-DIP packaging. However, it exhibits reduced slew rate (13 V/µs versus 45 V/µs), lower gain bandwidth product (5 MHz versus 10 MHz), and higher input bias current (7 pA versus 1 pA). Supply voltage range is restricted to 20 V to 36 V, eliminating compatibility with applications requiring 4.5 V minimum supply operation. This substitute is suitable only for applications where reduced bandwidth and slew rate are acceptable.

LT1356CN#PBF is not recommended as a direct substitute due to fundamental architectural differences. This part employs voltage feedback amplifier topology rather than J-FET input design, contains only 2 circuits instead of 4, and exhibits significantly different electrical characteristics including 400 V/µs slew rate, 12 MHz bandwidth, and 80 nA input bias current. While it maintains 14-DIP packaging and through-hole mounting, the reduced circuit count (2 versus 4) and different amplifier architecture make it unsuitable for applications requiring 4-channel J-FET amplification.

Frequently Asked Questions (FAQ)

Q: Can TLE2074ACN be used as a direct replacement for TLE2074ACNG4?

A: Yes. TLE2074ACN is the active production equivalent with identical electrical specifications, amplifier type, circuit count, and package format. The parts are electrically interchangeable. Packaging format differs (tube versus tape-and-reel), but this does not affect circuit performance.

Q: What are the key differences between TLE2074ACNG4 and LT1058CN#PBF?

A: Both parts are J-FET input 4-circuit amplifiers in 14-DIP packaging. However, LT1058CN#PBF has reduced slew rate (13 V/µs versus 45 V/µs), lower gain bandwidth product (5 MHz versus 10 MHz), higher input bias current (7 pA versus 1 pA), and restricted supply voltage range (20 V to 36 V versus 4.5 V to 38 V). Substitution is valid only when reduced performance specifications are acceptable.

Q: Why is LT1356CN#PBF not recommended as a substitute?

A: LT1356CN#PBF uses voltage feedback amplifier architecture instead of J-FET input design and contains only 2 circuits instead of 4. These fundamental differences make it unsuitable for applications requiring 4-channel J-FET amplification, despite maintaining 14-DIP packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLE2074ACN, LT1058CN#PBF, and LT1356CN#PBF are all ROHS3 compliant and REACH unaffected, matching the compliance status of TLE2074ACNG4.

Q: What is the primary reason for substituting TLE2074ACNG4?

A: TLE2074ACNG4 is classified as obsolete. TLE2074ACN is the active production equivalent recommended for new designs and ongoing procurement to ensure long-term supply chain stability.

Q: Can these parts be used interchangeably in existing PCB designs?

A: TLE2074ACN is pin-compatible and electrically identical, enabling direct substitution without PCB modification. LT1058CN#PBF and LT1356CN#PBF are physically compatible (14-DIP package, through-hole mounting) but may require circuit design verification due to different electrical specifications.

Q: What supply voltage range is supported by all substitute options?

A: TLE2074ACN supports 4.5 V to 38 V, matching TLE2074ACNG4. LT1058CN#PBF supports 20 V to 36 V. LT1356CN#PBF supports 5 V to 30 V. Applications requiring operation below 5 V must use TLE2074ACN or TLE2074ACNG4.
