• Mounting Type: Through Hole
• Operating Temperature Range: Minimum 0°C to 70°C coverage

Secondary Compatibility Parameters:

• Slew Rate: 13 V/µs or greater
• Gain Bandwidth Product: 3 MHz or greater
• Current - Input Bias: 30 pA or lower

Parameter Comparison

Engineering Selection Recommendations

Tier 1: Direct Equivalents (Texas Instruments TL082 Series)

TL082BCP and TL082CP are active direct equivalents manufactured by Texas Instruments. Both devices maintain identical amplifier type (J-FET), circuit count (2), package configuration (8-DIP), and mounting type (Through Hole). TL082BCP provides the closest parameter match to TL082BCPG4, with identical slew rate (13 V/µs), gain bandwidth product (3 MHz), input bias current (30 pA), and input offset voltage (2 mV). TL082CP offers the same core specifications with relaxed input bias current (50 pA) and input offset voltage (5 mV) tolerances. Both are ROHS3 Compliant and carry Active product status, ensuring long-term availability.

Tier 2: Enhanced Performance Alternatives

TL082CP/NOPB (Texas Instruments) provides increased gain bandwidth product (4 MHz) and output current capability (17 mA per channel) within the same package. This variant operates at higher supply current (3.6 mA x2 Channels) and requires symmetric ±18 V supply (36 V span). LT1169CN8#PBF (Analog Devices) offers superior input bias current (4 pA) and input offset voltage (600 µV), with higher gain bandwidth product (5.3 MHz). The LT1169CN8#PBF operates across a wider supply range (9 V to 40 V) but requires higher supply current (5.3 mA x2 Channels). Both devices are ROHS3 Compliant and Active.

Tier 3: Functional Alternatives

NJM2749AD (Nisshinbo Micro Devices) maintains J-FET amplifier type with identical slew rate (13 V/µs) and dual-circuit configuration. This device operates across extended temperature range (-40°C to 85°C) and is RoHS Compliant. Supply voltage range (12 V to 32 V) differs from the original specification. MUSES8820D (Nisshinbo Micro Devices) represents a functional alternative with Audio amplifier type classification. This device provides significantly higher gain bandwidth product (11 MHz) and output current (50 mA per channel), with extended operating temperature (-40°C to 85°C). MUSES8820D operates at lower minimum supply voltage (7 V) but requires higher supply current (8 mA). Input bias current specification (100 nA) exceeds the original device requirement.

Selection Criteria by Application:

For direct pin-compatible replacement with minimal circuit redesign, select TL082BCP or TL082CP. For applications requiring lower input bias current and improved offset voltage specifications, select LT1169CN8#PBF. For extended temperature operation, select NJM2749AD or MUSES8820D. All recommended substitutes maintain 8-DIP through-hole package compatibility and RoHS/REACH compliance.

Frequently Asked Questions (FAQ)

Q1: Can TL082BCP directly replace TL082BCPG4 without circuit modification?

A: Yes. TL082BCP maintains identical electrical specifications for slew rate (13 V/µs), gain bandwidth product (3 MHz), input bias current (30 pA), input offset voltage (2 mV), supply current (1.4 mA x2 Channels), and output current (10 mA per channel). Both devices operate across 10 V to 30 V supply range and share the 8-DIP through-hole package. No circuit redesign is required.

Q2: What is the difference between TL082BCP and TL082CP?

A: TL082BCP and TL082CP differ in input bias current and input offset voltage specifications. TL082BCP specifies 30 pA input bias current and 2 mV input offset voltage. TL082CP specifies 50 pA input bias current and 5 mV input offset voltage. Both maintain identical slew rate (13 V/µs), gain bandwidth product (3 MHz), and supply specifications. TL082BCP provides tighter input specifications; TL082CP offers relaxed tolerances. Both are Active products with ROHS3 compliance.

Q3: Why does TL082CP/NOPB require different supply voltage specifications?

A: TL082CP/NOPB is specified for symmetric ±18 V supply operation (36 V total span), compared to the original TL082BCPG4 specification of 10 V to 30 V. This variant exhibits higher gain bandwidth product (4 MHz) and increased output current capability (17 mA per channel), requiring higher supply current (3.6 mA x2 Channels). Circuit redesign is necessary if supply voltage differs from ±18 V.

Q4: Is LT1169CN8#PBF a suitable replacement for low-noise applications?

A: LT1169CN8#PBF provides superior input specifications: input bias current of 4 pA (versus 30 pA) and input offset voltage of 600 µV (versus 2 mV). Gain bandwidth product is higher (5.3 MHz versus 3 MHz). However, supply current requirement is higher (5.3 mA x2 Channels versus 1.4 mA x2 Channels), and supply voltage range differs (9 V to 40 V). Circuit redesign is required to accommodate these parameter differences.

Q5: Can MUSES8820D replace TL082BCPG4 in all applications?

A: MUSES8820D is classified as an Audio amplifier rather than a J-FET operational amplifier. While it maintains dual-circuit 8-DIP through-hole package configuration, it exhibits significantly different electrical characteristics: higher gain bandwidth product (11 MHz), higher output current (50 mA per channel), higher supply current (8 mA), and higher input bias current (100 nA). MUSES8820D is suitable only for applications where these parameter differences are acceptable. Circuit redesign is required.

Q6: What is the significance of RoHS3 compliance versus RoHS compliance?

A: ROHS3 Compliant indicates full compliance with Restriction of Hazardous Substances Directive 3, including restrictions on lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. RoHS Compliant (without the "3" designation) indicates compliance with earlier RoHS standards. Both certifications are acceptable for most applications; ROHS3 represents the current standard.

Q7: Does extended operating temperature range (-40°C to 85°C) affect substitution compatibility?

A: Extended operating temperature range does not prevent substitution if the original application operates within 0°C to 70°C. NJM2749AD and MUSES8820D both specify -40°C to 85°C operating range, providing additional temperature margin. However, other electrical parameters must still align with application requirements. Extended temperature capability does not modify electrical performance within the 0°C to 70°C window.

Q8: Are all substitute parts available in Tube packaging?

A: Packaging availability varies. TL082BCP, TL082CP, and TL082CP/NOPB are specified in Tube packaging. LT1169CN8#PBF is specified in Tube packaging. NJM2749AD is specified in Tube packaging. MUSES8820D packaging is not specified in the provided data. Confirm packaging availability with component suppliers before final selection.

Q9: What inventory levels are available for each substitute part?

A: Current inventory levels are: TL082BCP (1900 Pcs), TL082CP (10300 Pcs), TL082CP/NOPB (911 Pcs), LT1169CN8#PBF (938 Pcs), NJM2749AD (812 Pcs), and MUSES8820D (2945 Pcs). Inventory levels are subject to change. Verify current availability with component suppliers.

Q10: Which substitute part offers the best long-term availability?

A: TL082CP carries Active product status with the highest current inventory (10300 Pcs). TL082BCP also carries Active status with substantial inventory (1900 Pcs). Both Texas Instruments TL082 series variants represent the most established long-term availability path. Analog Devices LT1169CN8#PBF and Nisshinbo devices (NJM2749AD, MUSES8820D) also carry Active status with adequate inventory levels.
