Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

TL082IP is the primary recommended substitute for the obsolete TL082IPG4. Both parts are manufactured by Texas Instruments, share identical J-FET amplifier architecture, and maintain equivalent electrical specifications including slew rate (13 V/µs), gain-bandwidth product (3 MHz), and input bias current (30 pA). The TL082IP is classified as an active product with 4100 units in stock. Operating temperature range extends from -40°C to 85°C, matching the original part. Supply voltage range (10 V to 30 V) and package configuration (8-DIP through-hole) are identical.

For Extended Temperature Operation with Reduced Performance Tolerance:

TL082CP is an active Texas Instruments product suitable for applications where operating temperature does not exceed 70°C. This part exhibits slightly higher input bias current (50 pA) and input offset voltage (5 mV) compared to the TL082IPG4. Supply voltage range and package configuration remain compatible. Inventory availability is substantial at 10300 units.

For General Purpose Applications with Enhanced Output Current:

AS358P-E1 (Diodes Incorporated) and CA3240AEZ (Renesas Electronics) are general purpose amplifiers compatible with the 8-DIP package and extended temperature range (-40°C to 85°C). These parts provide higher output current capability (40 mA per channel) and lower input offset voltage (2 mV). AS358P-E1 operates across a wider supply voltage range (3 V to 36 V) and features lower supply current (700 µA per channel). CA3240AEZ provides enhanced gain-bandwidth product (4.5 MHz) and extremely low input bias current (10 pA).

For Audio and High-Performance Applications:

MUSES8820D (Nisshinbo Micro Devices) is an audio-grade amplifier offering superior gain-bandwidth product (11 MHz), enhanced output current (50 mA per channel), and exceptional input offset voltage (300 µV). This part is suitable for applications prioritizing audio fidelity and dynamic performance. Operating temperature range (-40°C to 85°C) and 8-DIP package configuration are maintained. Supply voltage range (7 V to 32 V) overlaps with the original part specifications.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with current manufacturing standards. Moisture sensitivity levels vary; TL082IP carries no moisture sensitivity designation, while TL082IPG4, TL082CP/NOPB, AS358P-E1, CA3240AEZ, and MUSES8820D are classified as MSL 1 or MSL 2.

Frequently Asked Questions (FAQ)

Q: Can TL082IP be used as a direct replacement for TL082IPG4 in existing designs?

A: Yes. TL082IP is electrically and mechanically equivalent to TL082IPG4. Both parts share identical J-FET amplifier architecture, slew rate (13 V/µs), gain-bandwidth product (3 MHz), input bias current (30 pA), and operating temperature range (-40°C to 85°C). Package configuration (8-DIP through-hole) and supply voltage range (10 V to 30 V) are identical. TL082IP is an active product with substantial inventory availability.

Q: What is the difference between TL082IP and TL082CP?

A: TL082IP and TL082CP are both J-FET amplifiers from Texas Instruments with identical electrical specifications for slew rate, gain-bandwidth product, and supply voltage range. The primary difference is operating temperature range: TL082IP operates from -40°C to 85°C, while TL082CP operates from 0°C to 70°C. TL082CP exhibits slightly higher input bias current (50 pA versus 30 pA) and input offset voltage (5 mV versus 3 mV). Selection depends on application temperature requirements.

Q: Why would I choose a general purpose amplifier like AS358P-E1 or CA3240AEZ over the TL082IP?

A: General purpose amplifiers offer different performance trade-offs. AS358P-E1 provides lower supply current (700 µA per channel versus 1.4 mA) and wider supply voltage range (3 V to 36 V), making it suitable for battery-powered or low-power applications. CA3240AEZ offers extremely low input bias current (10 pA) and enhanced gain-bandwidth product (4.5 MHz). These alternatives are appropriate when application requirements differ from the original J-FET specifications.

Q: Is MUSES8820D compatible with TL082IPG4 designs?

A: MUSES8820D is mechanically compatible (8-DIP through-hole package) and operates across the same temperature range (-40°C to 85°C). However, electrical characteristics differ significantly. MUSES8820D is an audio-grade amplifier with higher gain-bandwidth product (11 MHz), lower input offset voltage (300 µV), and higher input bias current (100 nA). This part is suitable for audio applications where enhanced performance is required, but circuit design may require optimization for the different electrical characteristics.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are RoHS compliant (ROHS3 or RoHS Compliant designation). All parts maintain REACH unaffected status. These certifications ensure compatibility with current environmental and regulatory requirements.

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

A: The 8-DIP (Dual In-line Package) with 0.300" (7.62mm) body width is a through-hole package standard for dual operational amplifiers. All substitute parts maintain this identical package configuration, ensuring direct mechanical compatibility with existing printed circuit board layouts and socket configurations. No PCB redesign is required when substituting between parts with this package specification.

Q: Can I use TL082CP/NOPB as a substitute?

A: TL082CP/NOPB is an active Texas Instruments product with J-FET amplifier architecture and 8-DIP package compatibility. However, this part exhibits different electrical specifications: supply voltage range is fixed at 36 V (versus 10 V to 30 V for TL082IPG4), operating temperature range is 0°C to 70°C (versus -40°C to 85°C), and supply current is higher (3.6 mA per channel versus 1.4 mA). Selection of this part requires verification that application requirements align with these specifications.

Q: What inventory considerations should I evaluate?

A: TL082IP offers the highest inventory availability (4100 units) among active J-FET alternatives. TL082CP provides substantial stock (10300 units). AS358P-E1 has the largest overall inventory (67400 units) among all substitutes. MUSES8820D (2945 units) and CA3240AEZ (1744 units) have moderate availability. TL082CP/NOPB has limited stock (911 units). Procurement strategy should consider both technical compatibility and inventory levels for production continuity.
