TLE2021IDRG4 Equivalent & Substitute Parts

Part Overview

The TLE2021IDRG4 is a general-purpose operational amplifier manufactured by Texas Instruments, part of the Excalibur™ series. This device integrates one amplifier circuit in an 8-SOIC surface-mount package and is designed for applications requiring low input bias current and moderate bandwidth performance.

The TLE2021IDRG4 has been discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. The primary substitute is the TLE2021IDR, which maintains identical electrical and mechanical specifications while remaining in active production status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLE2021IDR

The TLE2021IDR is the direct equivalent to the TLE2021IDRG4. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. The TLE2021IDR is currently in active production status, ensuring supply chain continuity and long-term availability.

Compliance & Certification Alignment:

• Both parts maintain ROHS3 compliance
• Both parts carry REACH Unaffected status
• Both parts have MSL Rating 1 (Unlimited moisture sensitivity)
• Both parts are classified under ECCN EAR99 and HTSUS 8542.33.0001

Supply Availability: The TLE2021IDR is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and production-volume requirements. The TLE2021IDRG4 discontinuation does not impact functional compatibility; direct substitution is appropriate for all applications currently using the TLE2021IDRG4.

Frequently Asked Questions (FAQ)

Q: Can the TLE2021IDR be used as a direct replacement for the TLE2021IDRG4?

A: Yes. The TLE2021IDR is electrically and mechanically identical to the TLE2021IDRG4. All electrical parameters, package dimensions, and compliance certifications are equivalent. The primary difference is product status: TLE2021IDR is active, while TLE2021IDRG4 is discontinued.

Q: What is the difference between TLE2021IDRG4 and TLE2021IDR packaging?

A: The TLE2021IDRG4 was supplied in Digi-Reel® packaging. The TLE2021IDR is available in both Cut Tape (CT) and Digi-Reel® formats. Both use the same 8-SOIC package with identical pin configuration and mechanical dimensions (0.154" × 3.90mm width).

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical electrical specifications: 0.65 V/µs slew rate, 2 MHz gain bandwidth product, 25 nA input bias current, 120 µV input offset voltage, 240 µA supply current, and 20 mA output current per channel. Supply voltage range and operating temperature are also identical (4 V to 40 V, -40°C to 85°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLE2021IDRG4 and TLE2021IDR are ROHS3 compliant, REACH unaffected, and carry MSL Rating 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99.

Q: Why was the TLE2021IDRG4 discontinued?

A: The TLE2021IDRG4 discontinuation reflects standard product lifecycle management. The TLE2021IDR remains in active production and provides identical functionality, making it the recommended replacement for new designs and ongoing production.

Q: Can I use the TLE2021IDR in existing PCB designs that specify TLE2021IDRG4?

A: Yes. The TLE2021IDR is a direct pin-for-pin and functionally equivalent replacement. No PCB modifications are required. Both parts use the same 8-SOIC package with identical pinout and electrical characteristics.
