TL062BCD Equivalent & Substitute Parts

Part Overview

The TL062BCD is a dual J-FET input operational amplifier manufactured by STMicroelectronics in an 8-SOIC surface mount package. This device is discontinued at DiGi Electronics and classified as a legacy component. The TL062BCD features low input bias current (30 nA), a gain bandwidth product of 1 MHz, and operates across a supply voltage range of 6 V to 36 V. Due to its discontinued status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance.

Substitute Part Grouping Explanation

Substitution of the TL062BCD is determined by alignment across the following critical parameters: amplifier type (J-FET vs. general purpose), number of circuits (dual configuration), package form factor (8-SOIC), supply voltage range compatibility, input bias current characteristics, and operating temperature range.

Substitute parts are grouped into two categories:

Direct Equivalents (J-FET Amplifiers): Parts maintaining J-FET input architecture with identical dual-circuit configuration, 1 MHz gain bandwidth product, and 3.5 V/µs slew rate. These include TL062BCDR, TL062ACDR, TL062ACPSR, TL062CD, and TL062CDR. These parts preserve the low input bias current characteristic (30 pA) essential for high-impedance signal conditioning applications.

Functional Alternatives (General Purpose Amplifiers): Parts with general purpose amplifier topology, dual-circuit configuration, and 8-SOIC packaging. These include AS358AMTR-G1, LM358ADR2G, and OPA2277MDTEP. These alternatives provide operational compatibility for applications where J-FET input characteristics are not mandatory, though they exhibit different input bias current and supply current specifications.

Engineering Selection Recommendations

For Direct Replacement (J-FET Architecture Required):

Select TL062BCDR (Texas Instruments, Active status) or TL062CDR (Texas Instruments, Active status) as primary equivalents. Both maintain J-FET input topology, dual-circuit configuration, 1 MHz gain bandwidth product, and 3.5 V/µs slew rate. TL062BCDR and TL062CDR are in active production with unlimited moisture sensitivity rating (MSL 1) and ROHS3 compliance. Note that Texas Instruments variants specify a minimum supply voltage of 10 V compared to the original STMicroelectronics 6 V minimum; verify supply voltage compatibility in target applications.

TL062CD (STMicroelectronics, Active status) provides an alternative with the original 6 V to 36 V supply range, maintaining full electrical equivalence to the TL062BCD while offering active product status and higher inventory availability (145,300 units).

For Functional Substitution (General Purpose Amplifier Acceptable):

Select LM358ADR2G (onsemi, Active status) for applications where J-FET input characteristics are not critical. This part offers dual general-purpose amplifier configuration in 8-SOIC packaging, 1 MHz gain bandwidth product, and active production status. Supply voltage range is 3 V to 32 V. Input bias current is 45 nA, higher than the TL062BCD but acceptable for many signal conditioning applications.

AS358AMTR-G1 (Diodes Incorporated, Active status) provides extended operating temperature range (−40°C to 85°C) and lower input bias current (20 nA) compared to LM358ADR2G, with supply voltage range of 3 V to 36 V. Higher supply current (700 µA) and output current (40 mA) may impact power budget in battery-powered designs.

OPA2277MDTEP (Texas Instruments, Active status) is suitable for precision applications requiring lower input offset voltage (20 µV) and extended temperature range (−55°C to 125°C), though higher supply current (790 µA) and lower slew rate (0.8 V/µs) must be evaluated against application requirements.

All recommended substitutes are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can TL062BCDR directly replace the original TL062BCD from STMicroelectronics?

A: TL062BCDR is electrically equivalent with identical J-FET amplifier topology, dual-circuit configuration, slew rate (3.5 V/µs), and gain bandwidth product (1 MHz). Both maintain 30 pA input bias current and 2 mV input offset voltage. The primary difference is the minimum supply voltage: TL062BCDR requires 10 V minimum versus 6 V for the original. Verify that your application supply voltage meets or exceeds 10 V. TL062BCDR is in active production status, making it the recommended direct replacement.

Q: What is the difference between J-FET and general purpose amplifier substitutes?

A: J-FET input amplifiers (TL062 series) feature extremely low input bias current (30 pA) and are optimized for high-impedance signal sources where input current leakage must be minimized. General purpose amplifiers (LM358, AS358, OPA2277) use bipolar input stages with higher input bias current (20 nA to 500 pA) but offer broader supply voltage ranges and extended temperature ratings. Select J-FET substitutes for impedance-sensitive applications; general purpose alternatives are suitable for standard signal conditioning where input bias current is not a limiting factor.

Q: Are all substitute parts available in the same 8-SOIC package?

A: All recommended substitutes are packaged in 8-SOIC (0.154", 3.90mm width) surface mount configuration, ensuring PCB layout compatibility. TL062ACPSR uses an 8-SO package (0.209", 5.30mm width), which is mechanically incompatible with standard 8-SOIC footprints. Verify package designation before selecting this alternative.

Q: What is the impact of higher supply current in general purpose alternatives?

A: General purpose amplifiers exhibit higher supply current per channel: LM358ADR2G draws 800 µA (x2 channels) compared to 200 µA for TL062BCD. AS358AMTR-G1 draws 700 µA (x2 channels). In battery-powered or power-constrained applications, this increased current consumption reduces operating time or requires larger power supplies. Evaluate total system power budget before selecting general purpose alternatives.

Q: Can OPA2277MDTEP be used in applications requiring 3.5 V/µs slew rate?

A: OPA2277MDTEP has a slew rate of 0.8 V/µs, significantly lower than the TL062BCD specification of 3.5 V/µs. This device is unsuitable for applications requiring fast signal transient response or high-frequency signal conditioning. Select OPA2277MDTEP only for precision DC or low-frequency applications where slew rate is not a performance constraint.

Q: What is the significance of product status (Active vs. Last Time Buy vs. Discontinued)?

A: Active status indicates ongoing production with stable long-term availability. Last Time Buy indicates the manufacturer has announced end-of-life; existing inventory is available but no future production is planned. Discontinued status means the part is no longer manufactured or supported. For new designs or long-term production, select parts with Active status (TL062BCDR, TL062CDR, TL062CD, AS358AMTR-G1, LM358ADR2G, OPA2277MDTEP). For legacy system maintenance, Last Time Buy parts (TL062BCD from Texas Instruments, TL062ACPSR) may be acceptable if inventory is secured.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts listed in this document are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.
