TL022CPSRG4 Equivalent & Substitute Parts

Part Overview

The TL022CPSRG4 is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a dual-channel amplifier in an 8-SO surface mount package. This device is classified as Last Time Buy, indicating limited future availability from the manufacturer. The TL022CPSRG4 operates across a wide supply voltage range and is suitable for general-purpose amplification applications requiring low input bias current and moderate bandwidth characteristics.

Identification of equivalent and substitute parts is necessary due to the Last Time Buy status of the TL022CPSRG4. Alternative part numbers within the TL022 series provide functionally identical electrical performance while offering different packaging formats and current product availability status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL022CPSRG4 is determined by electrical and mechanical parameter equivalence within the TL022 operational amplifier series. All substitute parts maintain identical electrical specifications across the following critical parameters:

• Dual-channel general-purpose amplifier configuration
• Slew rate of 0.5 V/µs
• Gain bandwidth product of 500 kHz
• Input bias current of 100 nA
• Input offset voltage of 1 mV
• Supply current of 130 µA per channel pair
• Output current capability of 6 mA per channel
• Supply voltage range from 10 V to 30 V
• Operating temperature range of 0°C to 70°C
• Surface mount technology
• Identical regulatory compliance (ROHS3, REACH Unaffected)

Substitute parts differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and physical package dimensions, which do not affect electrical functionality or circuit performance.

Engineering Selection Recommendations

TL022CDR is the primary recommended substitute for the TL022CPSRG4. This part maintains complete electrical equivalence and is classified as Active product status, ensuring continued availability and long-term supply chain reliability. The TL022CDR is supplied in Cut Tape & Digi-Reel packaging format and features a narrower 8-SOIC package body (0.154" width versus 0.209" width). This dimensional difference does not affect electrical performance and may provide advantages in space-constrained PCB layouts. Current inventory of 18,100 units supports immediate procurement requirements.

TL022CPSR serves as a secondary substitute option. This part is electrically identical to the TL022CPSRG4 and maintains the same 8-SOIC package body width (0.209"). However, the TL022CPSR carries Last Time Buy status identical to the main part, indicating limited future availability. This part is suitable for applications where packaging format consistency with the TL022CPSRG4 is required, though the TL022CDR is preferred for new designs due to its Active product status.

All three parts comply with ROHS3 and REACH regulations, ensuring regulatory compliance across all substitute selections.

Frequently Asked Questions (FAQ)

Q: Can the TL022CDR be used as a direct replacement for the TL022CPSRG4 in existing designs?

A: Yes. The TL022CDR is electrically identical to the TL022CPSRG4 across all specified parameters. The primary difference is the package body width (0.154" versus 0.209"), which does not affect electrical functionality. PCB layout modifications may be required to accommodate the narrower package body if the original design was optimized for the wider 0.209" dimension.

Q: What is the significance of the packaging format difference between Tape & Reel and Cut Tape & Digi-Reel?

A: Packaging format affects handling, storage, and automated assembly processes. Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides flexibility for lower-volume production or mixed-component assembly. Both formats contain identical die and electrical performance. Selection depends on manufacturing process requirements rather than circuit functionality.

Q: Why is the TL022CDR recommended over the TL022CPSR despite identical electrical specifications?

A: The TL022CDR carries Active product status, indicating ongoing manufacturer support and guaranteed long-term availability. The TL022CPSR, like the TL022CPSRG4, is classified as Last Time Buy, signaling limited future production. For new designs or long-term production requirements, the Active status of the TL022CDR provides supply chain certainty.

Q: Are there any thermal or reliability differences between the substitute parts?

A: No thermal or reliability differences exist between the three parts. All three maintain identical operating temperature ranges (0°C to 70°C), identical moisture sensitivity levels (MSL 1), and identical regulatory compliance certifications. Thermal performance is determined by die design, which is identical across all TL022 variants.

Q: Does the narrower package body of the TL022CDR affect PCB routing or component spacing?

A: The TL022CDR's narrower 8-SOIC package body (0.154" width) may allow tighter component spacing compared to the 0.209" width of the TL022CPSRG4 and TL022CPSR. This can provide layout advantages in space-constrained applications. However, PCB design files must be updated to reflect the different package footprint dimensions to ensure proper component placement and solder pad alignment.

Q: What inventory considerations should guide part selection?

A: The TL022CDR offers the highest current inventory (18,100 units), supporting immediate procurement and reducing lead time risk. The TL022CPSRG4 (919 units) and TL022CPSR (3,609 units) have more limited inventory. For applications requiring large production quantities or long-term supply assurance, the TL022CDR is the optimal choice.
