Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2082CPG4 is determined by compatibility across the following critical parameters: package type (8-DIP through-hole), number of circuits (2), supply voltage range, and amplifier classification. The substitute parts are grouped into two categories based on amplifier type and performance characteristics.

Category 1: Direct J-FET Equivalents Parts maintaining J-FET input architecture with comparable electrical specifications. These substitutes preserve the high input impedance and low input bias current characteristics of the original device.

Category 2: General Purpose and Audio Amplifiers Parts offering alternative amplifier topologies (general purpose or audio) with different electrical performance profiles but compatible package and pin configurations. These substitutes accommodate applications where the specific J-FET characteristics are not mandatory.

Substitution eligibility is determined by:

• Package compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting
• Circuit count: 2 independent circuits
• Supply voltage range overlap with application requirements
• Product status: Active or Obsolete (for inventory availability)
• Compliance certifications: RoHS3 and REACH status

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TLE2082CP

The TLE2082CP is the manufacturer-recommended equivalent for the obsolete TLE2082CPG4. This part maintains identical electrical specifications including J-FET input architecture, 45 V/µs slew rate, 10 MHz gain bandwidth product, and 20 pA input bias current. The TLE2082CP is manufactured by Texas Instruments with Active product status, ensuring long-term availability and supply chain continuity. Both parts share identical package configuration (8-DIP through-hole) and operating temperature range (0°C to 70°C). The TLE2082CP is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Secondary Recommendation: LT1057CN8#PBF

The LT1057CN8#PBF is a J-FET input operational amplifier manufactured by Analog Devices Inc. with Active product status. This substitute maintains J-FET input characteristics with superior input bias current performance (7 pA versus 20 pA). The LT1057CN8#PBF operates within a 20 V to 36 V supply range, which overlaps with the TLE2082CPG4 maximum specification but requires minimum supply voltage of 20 V. The device delivers 13 V/µs slew rate and 5 MHz gain bandwidth product, representing reduced performance compared to the original. The LT1057CN8#PBF is suitable for applications where lower input bias current and lower power consumption (1.7 mA versus 3.1 mA) are advantageous and where the reduced slew rate and bandwidth are acceptable.

Alternative Recommendation: AS358P-E1

The AS358P-E1 is a general-purpose operational amplifier manufactured by Diodes Incorporated with Active product status and high inventory availability (67,400 units). This substitute operates within a 3 V to 36 V supply range, providing broader low-voltage compatibility than the original device. The AS358P-E1 features significantly lower supply current (700 µA versus 3.1 mA), making it suitable for power-constrained applications. Input bias current is 20 nA (1000 times higher than the original), and input offset voltage is 2 mV (higher than the original 1.1 mV). The AS358P-E1 is appropriate for applications where J-FET input characteristics are not critical and where power efficiency is prioritized.

Alternative Recommendation: OP275GPZ

The OP275GPZ is an audio-grade operational amplifier manufactured by Analog Devices Inc. with Active product status. This substitute operates within a 9 V to 44 V supply range and delivers 22 V/µs slew rate and 9 MHz gain bandwidth product. The OP275GPZ provides higher output current capability (90 mA versus 48 mA) and is optimized for audio applications. Input bias current is 100 nA, and input offset voltage is 1 mV. This substitute is suitable for audio signal processing applications where the higher output current and slew rate provide performance advantages.

All recommended substitutes maintain through-hole 8-DIP package compatibility, dual-circuit configuration, and regulatory compliance (ROHS3 and REACH unaffected status).

Frequently Asked Questions (FAQ)

Q: Can the TLE2082CP directly replace the TLE2082CPG4 without circuit modifications?

A: Yes. The TLE2082CP is the manufacturer-recommended equivalent with identical electrical specifications, package configuration, and pin assignment. No circuit modifications are required for direct substitution.

Q: What is the primary difference between the TLE2082CPG4 and TLE2082CP?

A: The TLE2082CPG4 is classified as Obsolete, while the TLE2082CP is Active. Both parts are functionally identical. The TLE2082CP is recommended for new designs and production continuity due to its active status and guaranteed long-term availability.

Q: Can the LT1057CN8#PBF be used as a direct replacement?

A: The LT1057CN8#PBF is a J-FET input substitute with compatible package and pin configuration. However, it operates with a minimum supply voltage of 20 V (versus 4.5 V for the original), reduced slew rate (13 V/µs versus 45 V/µs), and lower gain bandwidth product (5 MHz versus 10 MHz). Substitution requires verification that the application supply voltage meets the 20 V minimum requirement and that the reduced performance specifications are acceptable.

Q: Is the AS358P-E1 suitable for precision applications requiring low input bias current?

A: No. The AS358P-E1 is a general-purpose amplifier with 20 nA input bias current, which is 1000 times higher than the TLE2082CPG4 (20 pA). This substitute is appropriate for applications where input bias current is not a critical specification. For precision applications requiring low input bias current, the TLE2082CP or LT1057CN8#PBF are recommended.

Q: What are the supply voltage compatibility considerations for substitution?

A: The TLE2082CPG4 operates from 4.5 V to 38 V. Substitute parts have different supply voltage ranges: TLE2082CP (4.5 V to 38 V), AS358P-E1 (3 V to 36 V), BA15218 (4 V to 32 V), LT1057CN8#PBF (20 V to 36 V), MUSES8820D (7 V to 32 V), and OP275GPZ (9 V to 44 V). Substitution requires verification that the application supply voltage falls within the substitute part's specified range.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS compliant. The TLE2082CP, AS358P-E1, BA15218, LT1057CN8#PBF, and OP275GPZ are ROHS3 compliant. The MUSES8820D is RoHS compliant. All parts are REACH unaffected.

Q: What is the significance of the 8-DIP package specification?

A: The 8-DIP (0.300", 7.62mm) package is a through-hole dual inline package with 8 pins. All substitute parts maintain this identical package configuration, ensuring mechanical and electrical compatibility with existing printed circuit board layouts and socket configurations. No PCB redesign is required for substitution.

Q: Can multiple substitute parts be used interchangeably within the same application?

A: No. Each substitute part has distinct electrical characteristics. Selection must be based on specific application requirements including supply voltage range, slew rate, gain bandwidth product, input bias current, and output current specifications. Interchangeability is not guaranteed across different substitute parts.

Q: What inventory considerations should be evaluated for substitution?

A: The TLE2082CPG4 has 1,152 units in stock (Obsolete status). The TLE2082CP has 2,200 units available (Active status). The AS358P-E1 has the highest inventory at 67,400 units. For long-term production requirements, the TLE2082CP or AS358P-E1 are recommended due to active product status and higher inventory levels.

Q: Is the operating temperature range a critical substitution parameter?

A: Yes. The TLE2082CPG4 operates from 0°C to 70°C. Substitute parts have different temperature ranges: TLE2082CP (0°C to 70°C), AS358P-E1 (-40°C to 85°C), BA15218 (-40°C to 85°C), LT1057CN8#PBF (0°C to 70°C), MUSES8820D (-40°C to 85°C), and OP275GPZ (-40°C to 85°C). Applications requiring operation below 0°C or above 70°C must select substitute parts with extended temperature ranges.
