TL062IPG4 Equivalent & Substitute Parts

Part Overview

The TL062IPG4 is a J-FET input operational amplifier featuring two independent circuits in an 8-DIP package. This device is designed for applications requiring low input bias current and low input offset voltage characteristics. The TL062IPG4 is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the TL062IPG4 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62 mm) through-hole package to ensure direct board-level compatibility.

Circuit Count: The device contains two independent amplifier circuits, requiring substitutes with identical circuit configuration.

Operating Temperature Range: All substitutes must support the -40°C to 85°C operating temperature range.

Supply Voltage Range: Substitutes must accommodate the 10 V to 30 V supply span requirement.

Compliance Requirements: All substitutes must maintain ROHS3 compliance and REACH unaffected status.

The TL062IP represents a direct equivalent with identical electrical specifications and active product status. The AS358P-E1 represents a functional substitute with different amplifier topology (general purpose versus J-FET) but compatible package, pin count, and operating parameters within the specified ranges.

Engineering Selection Recommendations

TL062IP (Texas Instruments): This part is the manufacturer-recommended equivalent for the discontinued TL062IPG4. It maintains identical electrical specifications, J-FET amplifier topology, and supply voltage range. The TL062IP is currently in active production status with substantial inventory availability. This part is the primary selection for direct replacement applications requiring preservation of original circuit performance characteristics.

AS358P-E1 (Diodes Incorporated): This part functions as a functional substitute with compatible package and pin configuration. The AS358P-E1 employs general-purpose amplifier topology rather than J-FET input architecture. Key differences include higher input bias current (20 nA versus 30 pA), lower supply voltage minimum (3 V versus 10 V), higher output current capability (40 mA versus 20 mA), and higher supply current consumption (700 µA versus 200 µA). The AS358P-E1 is suitable for applications where the lower input bias current and specific J-FET characteristics of the TL062 are not critical design requirements. This part is in active production with high inventory availability.

Both substitute options maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original device.

Frequently Asked Questions (FAQ)

Q: Can the TL062IP be used as a direct replacement for the TL062IPG4?

A: Yes. The TL062IP is the active equivalent with identical electrical specifications, amplifier topology, and package configuration. The primary difference is product status: TL062IPG4 is discontinued while TL062IP is in active production.

Q: What are the key differences between the TL062IP and AS358P-E1?

A: The TL062IP maintains J-FET input architecture with 30 pA input bias current and requires 10 V minimum supply voltage. The AS358P-E1 uses general-purpose amplifier topology with 20 nA input bias current and operates from 3 V minimum supply voltage. The AS358P-E1 provides higher output current (40 mA versus 20 mA) but consumes more supply current (700 µA versus 200 µA).

Q: Are all substitute parts compatible with the original 8-DIP through-hole footprint?

A: Yes. All listed substitutes use the 8-DIP (0.300", 7.62 mm) through-hole package, ensuring direct board-level compatibility without layout modifications.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. Both TL062IP and AS358P-E1 support the -40°C to 85°C operating temperature range specified for the TL062IPG4.

Q: Which substitute is appropriate for low-power applications?

A: The TL062IP maintains the original 200 µA supply current specification, making it suitable for low-power designs. The AS358P-E1 requires 700 µA supply current and is appropriate for applications where higher output current capability is beneficial.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both TL062IP and AS358P-E1 are ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with the original TL062IPG4.
