TL071ACN Equivalent & Substitute Parts

Part Overview

The TL071ACN is a J-FET input operational amplifier manufactured by STMicroelectronics, housed in an 8-DIP through-hole package. This device is classified as obsolete, though 2000 units remain in stock. The TL071ACN serves applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and long-term supply assurance.

Engineering Selection Recommendations

Tier 1 Substitutes (Highest Compatibility):

TL071BCP and TL071CP are direct substitutes from the same TL071 base product family manufactured by Texas Instruments. Both maintain active product status, ensuring long-term availability. TL071BCP offers superior input offset voltage specification (2 mV versus 3 mV). TL071CP provides the highest inventory availability (22,300 units). Both operate within the required temperature range and maintain full voltage supply span compatibility.

Tier 2 Substitutes (Extended Temperature Range):

TL071IP extends the operating temperature range to -40°C to 85°C, providing broader environmental coverage while maintaining all other electrical specifications identical to TL071CP. This variant is suitable for applications requiring industrial or extended temperature operation.

Tier 3 Substitutes (Reduced Bandwidth):

TL081ACP and TL081CP are from the TL081 base product family with reduced gain bandwidth product (3 MHz versus 4 MHz). These devices maintain lower input bias current (30 pA versus 20 pA for the main part) and support the full voltage supply span (7 V to 36 V). TL081CP offers the highest inventory availability among all substitutes (88,892 units).

Tier 4 Substitute (Alternative Series):

LF356N/NOPB is a BI-FET™ series device from Texas Instruments with 5 MHz gain bandwidth product. This part exhibits higher supply current (5 mA versus 1.4 mA) and operates within a fixed 30 V supply span, limiting its applicability to designs not requiring the full 6 V to 36 V range of the main part.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can TL071ACP, TL071BCP, and TL071CP be used interchangeably with TL071ACN?

A: Yes. All three parts are from the TL071 base product family with identical electrical specifications for supply current, output current, and supply voltage range. They share the same 8-DIP package and through-hole mounting. The primary difference is TL071BCP offers tighter input offset voltage specification (2 mV). All three are active products from Texas Instruments.

Q: What is the difference between TL071CP and TL081CP?

A: Both are J-FET operational amplifiers in 8-DIP packages from Texas Instruments. The TL071CP has a gain bandwidth product of 5.25 MHz, while TL081CP has 3 MHz. The TL081CP has lower input bias current (30 pA versus 65 pA). For applications requiring the 4 MHz bandwidth of the original TL071ACN, TL071CP is the more appropriate choice.

Q: Is TL071IP suitable for all applications where TL071ACN is used?

A: TL071IP is electrically identical to TL071CP but extends the operating temperature range to -40°C to 85°C. It is suitable for all applications where TL071ACN is used, with the added benefit of broader temperature operation. Use TL071IP when extended temperature range is required or beneficial.

Q: Why does LF356N/NOPB have higher supply current than other substitutes?

A: LF356N/NOPB is from the BI-FET™ series with different internal architecture, resulting in 5 mA supply current versus 1.4 mA for TL071 and TL081 series devices. This higher current consumption may impact power budget in battery-powered or low-power applications. LF356N/NOPB is suitable only for designs where the 5 mA supply current is acceptable.

Q: Can I use TL081ACP or TL081CP if my circuit requires 4 MHz bandwidth?

A: TL081ACP and TL081CP have 3 MHz gain bandwidth product, which is lower than the 4 MHz specification of TL071ACN. These parts are not suitable for applications with strict 4 MHz bandwidth requirements. Use TL071ACP, TL071BCP, or TL071CP instead, which provide 5.25 MHz bandwidth.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TL071ACP, TL071BCP, TL071CP, TL071IP, TL081ACP, TL081CP, and LF356N/NOPB) are ROHS3 compliant and REACH unaffected, matching the compliance status of TL071ACN.

Q: What is the minimum supply voltage for each substitute?

A: TL071ACP, TL071BCP, and TL071CP require minimum 10 V supply. TL081ACP and TL081CP require minimum 7 V supply. LF356N/NOPB requires 30 V fixed supply. The original TL071ACN operates from 6 V minimum. For applications requiring 6 V to 10 V operation, only TL081ACP or TL081CP are suitable.

Q: Which substitute has the best availability?

A: TL081CP has the highest inventory availability with 88,892 units in stock, followed by TL071CP with 22,300 units. Both are active products from Texas Instruments with established supply chains.
