Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE2021AIP are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Range: Minimum 4V, Maximum 40V
• RoHS Compliance: ROHS3 Compliant

Mechanical Compatibility Criteria:

• Package Type: 8-DIP through-hole configuration (0.300", 7.62mm)
• Mounting Type: Through Hole

Substitute parts are grouped into two categories based on packaging format:

Category 1: Through-Hole Package Substitutes Parts maintaining the 8-DIP through-hole package format for direct pin-compatible replacement.

Category 2: Surface-Mount Package Substitutes Parts with equivalent electrical specifications but in alternative surface-mount packages, requiring PCB redesign or adapter solutions.

Engineering Selection Recommendations

TLE2021AIDR (Texas Instruments) - Recommended for Electrical Equivalence

The TLE2021AIDR is the direct electrical equivalent of the TLE2021AIP, manufactured by the same supplier (Texas Instruments) within the same Excalibur™ series. This part maintains identical electrical specifications including slew rate (0.65 V/µs), gain bandwidth product (1.7 MHz), input bias current (25 nA), input offset voltage (80 µV), supply current (240 µA), and output current (20 mA). The operating temperature range (-40°C to 85°C) and supply voltage span (4V to 40V) are identical. The TLE2021AIDR is currently in Active product status, ensuring ongoing availability and support. The primary difference is packaging: TLE2021AIDR uses 8-SOIC surface-mount format instead of 8-DIP through-hole. This substitution requires PCB redesign or use of surface-mount to through-hole adapter solutions. Both parts are ROHS3 compliant.

OP90GPZ (Analog Devices Inc.) - Alternative for Through-Hole Applications

The OP90GPZ maintains the 8-DIP through-hole package format, eliminating the need for PCB redesign. This part is manufactured by Analog Devices Inc. and is currently in Active product status. The OP90GPZ shares the same operating temperature range (-40°C to 85°C) and general-purpose amplifier classification. However, electrical specifications differ significantly: the OP90GPZ exhibits lower slew rate (0.012 V/µs versus 0.65 V/µs), lower input bias current (4 nA versus 25 nA), higher input offset voltage (125 µV versus 80 µV), lower supply current (14 µA versus 240 µA), and lower output current (5 mA versus 20 mA). The supply voltage range is wider (1.6V to 36V). These differences indicate the OP90GPZ is optimized for low-power applications with relaxed speed and output current requirements. Selection of OP90GPZ requires verification that application performance tolerances accommodate the reduced slew rate and output current specifications.

Frequently Asked Questions (FAQ)

Q1: Can TLE2021AIDR be used as a direct replacement for TLE2021AIP without PCB modification?

A: No. While TLE2021AIDR is electrically identical to TLE2021AIP, the packaging differs. TLE2021AIP uses 8-DIP through-hole format (0.300", 7.62mm), while TLE2021AIDR uses 8-SOIC surface-mount format (0.154", 3.90mm Width). Direct substitution requires either PCB redesign to accommodate surface-mount soldering or use of a surface-mount to through-hole adapter. Pin assignments are compatible between these packages.

Q2: What are the key electrical differences between TLE2021AIP and OP90GPZ?

A: The primary electrical differences are: (1) Slew Rate: TLE2021AIP is 0.65 V/µs; OP90GPZ is 0.012 V/µs; (2) Input Bias Current: TLE2021AIP is 25 nA; OP90GPZ is 4 nA; (3) Input Offset Voltage: TLE2021AIP is 80 µV; OP90GPZ is 125 µV; (4) Supply Current: TLE2021AIP is 240 µA; OP90GPZ is 14 µA; (5) Output Current: TLE2021AIP is 20 mA; OP90GPZ is 5 mA. These differences indicate OP90GPZ is optimized for low-power operation with reduced speed and output drive capability.

Q3: Is OP90GPZ suitable for applications requiring high slew rate performance?

A: No. The OP90GPZ slew rate of 0.012 V/µs is significantly lower than the TLE2021AIP specification of 0.65 V/µs. Applications requiring fast signal transitions, high-frequency amplification, or rapid output changes should not use OP90GPZ as a substitute. Verify application slew rate requirements before selecting OP90GPZ.

Q4: Are all substitute parts RoHS3 compliant?

A: Yes. Both TLE2021AIDR and OP90GPZ are ROHS3 compliant, matching the compliance status of TLE2021AIP. All three parts are suitable for applications with RoHS compliance requirements.

Q5: What is the significance of TLE2021AIP being in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued or will discontinue production of TLE2021AIP. Customers requiring this component should transition to alternative parts. TLE2021AIDR (same manufacturer, active status) is the recommended transition path for electrical equivalence. OP90GPZ (alternative manufacturer, active status) is suitable for through-hole applications where electrical specification differences are acceptable.

Q6: Can TLE2021AIDR and OP90GPZ be used interchangeably in the same application?

A: No. While both are general-purpose operational amplifiers with the same operating temperature range, the electrical specifications differ substantially. TLE2021AIDR maintains identical electrical performance to TLE2021AIP. OP90GPZ has reduced slew rate, lower output current, and different input bias current characteristics. Selection between these parts depends on specific application requirements for speed, output drive capability, and power consumption.

Q7: What supply voltage ranges are supported by each substitute part?

A: TLE2021AIP and TLE2021AIDR both support 4V to 40V supply span. OP90GPZ supports a wider range of 1.6V to 36V. Applications operating at supply voltages below 4V or above 36V require careful evaluation of part suitability.
