TL082ACPSR Equivalent & Substitute Parts

Part Overview

The TL082ACPSR is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SO surface mount package. This part is classified as Last Time Buy, indicating discontinued production with limited remaining inventory of 8,353 pieces. The TL082ACPSR operates across a supply voltage range of 10V to 30V and is suitable for applications requiring low input bias current and moderate slew rate performance. Substitute parts are necessary due to product status transition and to ensure long-term design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL082ACPSR is determined by the following critical parameters: amplifier type (J-FET vs. General Purpose), number of circuits (2), surface mount package compatibility, supply voltage range, and operating temperature range. The substitute parts are grouped into two categories based on these criteria:

Category 1: Direct J-FET Substitutes (Preferred) Parts TL082ACDR, TL082CMX/NOPB, and TL082CM/NOPB maintain J-FET amplifier topology and dual-circuit configuration. These parts are electrically compatible with the TL082ACPSR within their specified parameter ranges. Packaging differences exist (8-SOIC width variations: 0.154" vs. 0.209"), but all are 8-pin SOIC surface mount packages suitable for standard PCB layouts.

Category 2: General Purpose Substitutes (Conditional) Parts MC33172D and MC33172DT are general-purpose operational amplifiers with dual-circuit configuration in 8-SOIC packages. These parts differ in amplifier type (General Purpose vs. J-FET) and exhibit different electrical characteristics, including lower slew rate (2V/µs vs. 13V/µs), lower gain bandwidth product (2.1MHz vs. 3MHz), and higher input bias current (20nA vs. 30pA). These parts are suitable only for applications where J-FET input characteristics are not required.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): TL082ACDR is the primary recommended substitute. It maintains identical electrical specifications to the TL082ACPSR (slew rate 13V/µs, gain bandwidth product 3MHz, input bias current 30pA, input offset voltage 3mV) and operates within the same supply voltage range (10V to 30V). The part is Active status with high inventory availability (100,098 pieces). The package width differs (0.154" vs. 0.209"), but both are standard 8-SOIC surface mount packages compatible with typical PCB layouts. All compliance certifications (ROHS3, MSL 1, REACH Unaffected) are identical.

For Extended Temperature Range Applications: MC33172DT or MC33172D provide extended operating temperature range (-40°C to 105°C vs. 0°C to 70°C) and wider supply voltage range (4V to 44V vs. 10V to 30V). These parts are suitable only for applications where J-FET input characteristics are not critical. The general-purpose amplifier topology results in significantly different electrical performance: lower slew rate (2V/µs), lower gain bandwidth product (2.1MHz), and substantially higher input bias current (20nA). Both parts are Active status with high inventory (100,400 and 45,300 pieces respectively).

For Equivalent Performance with Alternative Packaging: TL082CMX/NOPB and TL082CM/NOPB maintain J-FET topology and dual-circuit configuration. Both parts exhibit higher gain bandwidth product (4MHz vs. 3MHz) and higher input bias current (50pA vs. 30pA) compared to TL082ACPSR. Supply voltage range is fixed at 36V (vs. 10V to 30V range). These parts are Active status with lower inventory (2,264 and 2,200 pieces respectively).

All substitute parts are ROHS3 compliant, MSL 1 rated, and REACH unaffected, meeting the same environmental and regulatory requirements as the original part.

Frequently Asked Questions (FAQ)

Q: Can TL082ACDR be used as a direct drop-in replacement for TL082ACPSR? A: TL082ACDR is electrically equivalent to TL082ACPSR with identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The package width differs (0.154" vs. 0.209"), but both are 8-pin SOIC surface mount packages. PCB layout modifications may be required to accommodate the narrower package width. Verify PCB footprint compatibility before implementation.

Q: What are the key differences between J-FET and General Purpose amplifier types? A: J-FET input amplifiers (TL082 series) feature extremely low input bias current (30-50pA) and are suitable for high-impedance signal sources and precision instrumentation. General Purpose amplifiers (MC33172 series) have higher input bias current (20nA) but offer lower supply current consumption (220µA vs. 1.4-3.6mA) and extended temperature range. Selection depends on application requirements for input impedance and temperature performance.

Q: Are MC33172D and MC33172DT suitable substitutes for TL082ACPSR? A: MC33172D and MC33172DT are suitable only for applications where J-FET input characteristics are not required. These parts differ significantly in slew rate (2V/µs vs. 13V/µs), gain bandwidth product (2.1MHz vs. 3MHz), and input bias current (20nA vs. 30pA). Applications requiring high-speed signal processing or low input bias current should use TL082ACDR instead.

Q: What is the impact of supply voltage range differences? A: TL082ACPSR operates across 10V to 30V. TL082CMX/NOPB and TL082CM/NOPB are fixed at 36V supply. MC33172D and MC33172DT operate across 4V to 44V. Verify that the substitute part's supply voltage range encompasses the design's operating voltage before selection. Fixed-voltage parts require exact supply voltage matching.

Q: How do packaging differences affect PCB design? A: TL082ACPSR uses 8-SOIC with 0.209" (5.30mm) width. All substitute parts use 8-SOIC with 0.154" (3.90mm) width. The narrower package may fit existing footprints but requires verification of pad spacing and trace routing. Consult PCB layout guidelines and footprint libraries to confirm compatibility.

Q: What is the significance of Last Time Buy status for TL082ACPSR? A: Last Time Buy indicates that TL082ACPSR production has been discontinued. Current inventory of 8,353 pieces represents the final available stock. Once depleted, the part will no longer be available. Designs should transition to Active status substitutes (TL082ACDR, TL082CMX/NOPB, TL082CM/NOPB, MC33172D, or MC33172DT) to ensure long-term supply chain continuity.

Q: Are all substitute parts RoHS3 compliant? A: Yes. TL082ACPSR and all listed substitute parts (TL082ACDR, TL082CMX/NOPB, TL082CM/NOPB, MC33172D, MC33172DT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status. All parts meet identical environmental and regulatory requirements.
