Substitute Part Grouping Explanation

Substitution of the TL062IPWRG4 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-TSSOP surface mount package to ensure direct PCB layout compatibility without redesign.

Circuit Configuration: All substitutes must provide dual-channel (2 circuit) operational amplifier functionality.

Supply Voltage Range: Substitute parts must operate within the minimum 10 V to maximum 30 V supply span required by the original design, or provide a compatible subset of this range.

Electrical Performance: Key electrical characteristics including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capacity determine functional equivalence.

Compliance & Status: Substitute parts must maintain ROHS3 compliance and MSL 1 rating. Active product status is preferred for long-term availability, though the original part is obsolete.

The substitute parts are grouped into two categories: direct J-FET equivalents (TL062IPWR) and general-purpose amplifier alternatives (LM258PT, LM258WYPT, LM2904QTH-13) that provide functional substitution with modified electrical characteristics.

Engineering Selection Recommendations

TL062IPWR (Direct Equivalent): This part is the active-status equivalent of the TL062IPWRG4, manufactured by Texas Instruments. It maintains identical electrical specifications including J-FET amplifier type, 3.5 V/µs slew rate, 1 MHz gain bandwidth product, and 30 pA input bias current. The TL062IPWR operates within the same 10 V to 30 V supply range and provides the same 8-TSSOP package footprint. This substitute is recommended as the primary replacement for direct design continuity. Both parts are ROHS3 compliant with MSL 1 rating. The TL062IPWR is currently in active production with significantly higher inventory availability (16,439 units).

LM258PT (General Purpose Alternative): This STMicroelectronics part provides functional substitution with general-purpose amplifier characteristics. It operates across a lower minimum supply voltage (3 V) and maintains the 30 V maximum, offering broader supply flexibility. The LM258PT delivers higher output current capability (40 mA per channel versus 20 mA) and improved operating temperature range (-40°C to 105°C). However, it exhibits reduced slew rate (0.6 V/µs versus 3.5 V/µs) and significantly higher input bias current (20 nA versus 30 pA). This part is suitable for applications where low input bias current is not critical. The LM258PT carries AEC-Q100 automotive qualification and is ROHS3 compliant with MSL 1 rating.

LM258WYPT (General Purpose Alternative with Enhanced Output): This STMicroelectronics variant is functionally similar to the LM258PT but provides enhanced output current capability (60 mA per channel) and improved input offset voltage (2 mV versus 5 mV). It maintains the same general-purpose amplifier characteristics, lower minimum supply voltage (3 V), and extended operating temperature range (-40°C to 105°C). The LM258WYPT is supplied in Tape & Reel packaging and carries AEC-Q100 automotive qualification with ROHS3 compliance and MSL 1 rating.

LM2904QTH-13 (Extended Temperature Alternative): This Diodes Incorporated part offers the widest operating temperature range (-40°C to 125°C) and highest maximum supply voltage (36 V) among all substitutes. It provides general-purpose amplifier functionality with 40 mA output current per channel and 2 mV input offset voltage. The LM2904QTH-13 operates at the lowest minimum supply voltage (2 V), providing maximum supply flexibility. It exhibits the lowest slew rate (0.3 V/µs) and gain bandwidth product (700 kHz) among substitutes. This part is suitable for extended temperature applications and carries AEC-Q100 automotive qualification with ROHS3 compliance and MSL 1 rating.

A: AEC-Q100 qualification indicates these parts meet automotive-grade reliability and quality standards. This certification is relevant for applications requiring automotive-level component qualification, though the original TL062IPWRG4 does not carry this designation.

Q: Which substitute part offers the highest output current capability?

A: The LM258WYPT provides the highest output current per channel at 60 mA, compared to 20 mA for the original TL062IPWRG4 and 40 mA for the LM258PT and LM2904QTH-13.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TL062IPWR, LM258PT, LM258WYPT, LM2904QTH-13) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original TL062IPWRG4 compliance status.

Q: What is the operating temperature range difference between substitutes?

A: The original TL062IPWRG4 and TL062IPWR operate from -40°C to 85°C. The LM258PT and LM258WYPT extend to -40°C to 105°C. The LM2904QTH-13 provides the widest range at -40°C to 125°C.
