NJM082BD Equivalent & Substitute Parts

Part Overview

The NJM082BD is a J-FET operational amplifier featuring dual circuits in an 8-DIP through-hole package, manufactured by Nisshinbo Micro Devices Inc. This device is classified as obsolete, necessitating identification of active substitute components for ongoing design requirements and production continuity. The NJM082BD operates across a wide supply voltage range of 8V to 36V with low input bias current and moderate slew rate characteristics suitable for precision analog applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM082BD is determined by the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: J-FET architecture
• Number of Circuits: Dual-channel configuration
• Package Type: 8-DIP through-hole form factor
• Mounting Compatibility: Through-hole PCB mounting

Electrical Performance Alignment:

• Slew Rate: 13 V/µs (matching specification)
• Gain Bandwidth Product: 3 MHz (matching specification)
• Input Bias Current: 30 pA (matching specification)
• Supply Voltage Range: Minimum 10V to Maximum 30V (subset of original range)

The substitute parts TL082ACP and TL082BCP from Texas Instruments satisfy functional equivalence through identical J-FET amplifier architecture, dual-circuit configuration, and 8-DIP package geometry. Both substitutes maintain the critical electrical performance parameters of slew rate, gain bandwidth product, and input bias current. The substitutes operate within a narrower supply voltage window (10V–30V) compared to the original part (8V–36V), requiring verification of application-specific supply requirements.

Parameter Comparison

Engineering Selection Recommendations

TL082ACP and TL082BCP Selection Basis:

Both TL082ACP and TL082BCP are active products from Texas Instruments with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and production environments subject to environmental compliance requirements.

Differentiation Between Substitutes:

TL082BCP exhibits superior input offset voltage specification (2 mV) compared to TL082ACP (3 mV), representing tighter offset tolerance. Selection between these two substitutes depends on application-specific offset voltage requirements. Both substitutes maintain identical slew rate, gain bandwidth product, and input bias current specifications relative to the NJM082BD.

Supply Voltage Consideration:

Applications requiring operation below 10V or above 30V cannot use TL082ACP or TL082BCP as direct substitutes. The NJM082BD operates across 8V–36V, while both Texas Instruments substitutes operate across 10V–30V. Circuit designs operating within the 10V–30V window are fully compatible with either substitute.

Operating Temperature Consideration:

The NJM082BD supports extended temperature operation (-40°C to 85°C), while both substitutes operate across 0°C to 70°C. Applications requiring operation below 0°C or above 70°C cannot use these substitutes.

Frequently Asked Questions (FAQ)

Q: Are TL082ACP and TL082BCP pin-compatible with NJM082BD?

A: Yes. All three devices use 8-DIP through-hole packaging with 0.300" (7.62mm) spacing. Pin configuration is identical across all three parts, enabling direct PCB substitution without layout modification.

Q: What is the primary difference between TL082ACP and TL082BCP?

A: The primary difference is input offset voltage specification. TL082BCP specifies 2 mV maximum offset voltage, while TL082ACP specifies 3 mV. Both maintain identical slew rate (13 V/µs), gain bandwidth product (3 MHz), and input bias current (30 pA) specifications.

Q: Can NJM082BD be replaced in applications using supply voltages below 10V?

A: No. Both TL082ACP and TL082BCP require minimum 10V supply voltage, while NJM082BD operates at 8V minimum. Applications using 8V or 9V supplies require alternative substitutes or continued use of NJM082BD inventory.

Q: Can NJM082BD be replaced in applications requiring operation above 85°C?

A: No. Both TL082ACP and TL082BCP operate to maximum 70°C, while NJM082BD operates to 85°C. High-temperature applications cannot use these substitutes.

Q: Are the Texas Instruments substitutes suitable for new product designs?

A: Yes. Both TL082ACP and TL082BCP are active products with ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs.

Q: What is the supply current difference between NJM082BD and the substitutes?

A: NJM082BD specifies 3 mA total supply current, while TL082ACP and TL082BCP specify 1.4 mA per channel (2.8 mA total for dual channels). The substitutes exhibit lower supply current consumption.

Q: Can both substitutes be used interchangeably in the same application?

A: Yes, within the specified operating parameters. Both maintain identical functional performance for slew rate, gain bandwidth product, and input bias current. Selection between them depends on input offset voltage tolerance requirements specific to the application.
