TLE2021IP Equivalent & Substitute Parts

Part Overview

The TLE2021IP is a general-purpose operational amplifier manufactured by Texas Instruments in the Excalibur™ series. It is packaged in an 8-DIP (0.300", 7.62mm) through-hole configuration and is currently designated as Last Time Buy status. The device integrates one amplifier circuit suitable for general-purpose signal conditioning and amplification applications across industrial and consumer electronics.

Finding equivalent and substitute parts becomes necessary when the TLE2021IP reaches end-of-life, when alternative packaging formats are required for manufacturing flexibility, or when inventory constraints necessitate sourcing from alternative suppliers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2021IP is determined by strict electrical and mechanical compatibility criteria. The following parameters establish the substitution basis:

Primary Electrical Compatibility Criteria:

• Amplifier Type: General Purpose (single circuit)
• Slew Rate: 0.65 V/µs
• Gain Bandwidth Product: 2 MHz
• Current - Input Bias: 25 nA
• Voltage - Input Offset: 120 µV
• Current - Supply: 240 µA
• Current - Output / Channel: 20 mA
• Voltage - Supply Span: 4 V to 40 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Compatibility Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm) through-hole configuration
• Pin count and footprint must match for direct board-level substitution

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

Category 1: Direct Package Match (Through-Hole 8-DIP) Parts maintaining identical 8-DIP through-hole packaging enable direct socket replacement without PCB redesign.

Category 2: Alternative Packaging (Surface Mount) Parts with equivalent electrical specifications but different packaging formats (8-SOIC) require PCB layout modification and are suitable for new designs or board revisions.

Engineering Selection Recommendations

TLE2021IDR (Texas Instruments, 8-SOIC Surface Mount)

The TLE2021IDR is the manufacturer-recommended substitute from Texas Instruments. It maintains identical electrical specifications to the TLE2021IP, including slew rate (0.65 V/µs), gain bandwidth product (2 MHz), input bias current (25 nA), input offset voltage (120 µV), supply current (240 µA), and output current (20 mA). The device operates across the same voltage supply range (4 V to 40 V) and temperature range (-40°C to 85°C).

The primary distinction is packaging format: TLE2021IDR uses 8-SOIC surface-mount technology versus the through-hole 8-DIP of the TLE2021IP. This substitution is appropriate for new PCB designs or board revisions where surface-mount assembly is preferred. The TLE2021IDR carries Active product status and ROHS3 compliance, with higher inventory availability (7600 pcs) compared to the main part.

OP90GPZ (Analog Devices Inc., 8-DIP Through Hole)

The OP90GPZ is a through-hole 8-DIP alternative from Analog Devices Inc., enabling direct socket replacement without PCB modification. However, electrical specifications differ significantly from the TLE2021IP. The OP90GPZ exhibits substantially lower slew rate (0.012 V/µs versus 0.65 V/µs), lower input bias current (4 nA versus 25 nA), lower supply current (14 µA versus 240 µA), and lower output current per channel (5 mA versus 20 mA).

The OP90GPZ operates across a wider minimum supply voltage range (1.6 V versus 4 V) and slightly narrower maximum supply voltage (36 V versus 40 V). These electrical differences indicate the OP90GPZ is suitable only for applications where the reduced performance specifications are acceptable. The device carries Active product status and ROHS3 compliance.

Selection Criteria:

• For new designs with surface-mount capability: Select TLE2021IDR for manufacturer continuity and identical electrical performance.
• For through-hole replacement with identical performance: Verify availability of TLE2021IP or consider board redesign for TLE2021IDR adoption.
• For through-hole replacement with reduced performance requirements: OP90GPZ is suitable only when lower slew rate, reduced output current, and lower supply current are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q1: Can TLE2021IDR be used as a direct replacement for TLE2021IP on existing PCBs?

No. The TLE2021IDR uses 8-SOIC surface-mount packaging while the TLE2021IP uses 8-DIP through-hole packaging. Direct socket replacement is not possible without PCB redesign and rework. The TLE2021IDR is suitable for new board designs or board revisions incorporating surface-mount assembly.

Q2: What are the key electrical differences between TLE2021IP and OP90GPZ?

The OP90GPZ has significantly different electrical characteristics: slew rate is 0.012 V/µs (versus 0.65 V/µs), input bias current is 4 nA (versus 25 nA), supply current is 14 µA (versus 240 µA), and output current is 5 mA (versus 20 mA). These differences make OP90GPZ unsuitable for applications requiring the higher performance specifications of the TLE2021IP.

Q3: Are all substitute parts RoHS3 compliant?

Yes. Both TLE2021IDR and OP90GPZ are ROHS3 compliant, matching the compliance status of the TLE2021IP.

Q4: Which substitute part has the best inventory availability?

TLE2021IDR has the highest inventory availability at 7600 pcs, compared to 1363 pcs for OP90GPZ and 2950 pcs for the main TLE2021IP part.

Q5: Can OP90GPZ be used in applications designed for TLE2021IP?

Only if the application can tolerate the reduced electrical performance specifications. The OP90GPZ's lower slew rate, reduced output current capability, and lower supply current may not meet the requirements of circuits originally designed for TLE2021IP performance levels. Circuit simulation or prototype testing is necessary to confirm compatibility.

Q6: What is the operating temperature range for all parts?

All three parts operate across the identical temperature range of -40°C to 85°C.

Q7: What supply voltage ranges are supported?

TLE2021IP and TLE2021IDR support 4 V to 40 V. OP90GPZ supports 1.6 V to 36 V, offering lower minimum voltage but slightly lower maximum voltage.
