TL062CPSR Equivalent & Substitute Parts

Part Overview

The TL062CPSR is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SO surface mount package. This component is classified as Last Time Buy, indicating discontinued production status. The TL062CPSR operates across a 10V to 30V supply range with low input bias current (30 pA) and moderate slew rate (3.5V/µs), making it suitable for precision analog signal conditioning applications requiring low input offset voltage (3 mV).

Due to Last Time Buy status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL062CPSR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: Dual-channel (2 circuits)
• Mounting Type: Surface Mount
• Package Family: 8-SOIC form factor

Electrical Performance Boundaries:

• Supply voltage range must encompass or exceed the 10V to 30V requirement
• Input bias current must not exceed 30 pA (lower values acceptable)
• Input offset voltage must not exceed 3 mV (lower values acceptable)
• Output current per channel must support minimum 20 mA
• Slew rate and gain bandwidth product may vary without affecting basic substitutability

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level 1 required

Two substitute parts meet these criteria with varying performance enhancements.

Parameter Comparison

Engineering Selection Recommendations

TL062CDR (Texas Instruments)

The TL062CDR is the direct functional equivalent manufactured by Texas Instruments. It maintains identical electrical specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current) while offering Active product status. The primary difference is packaging width (3.90mm versus 5.30mm), which represents a physical footprint reduction. This substitute is suitable for direct replacement in new designs or redesigns where PCB space optimization is beneficial. Compliance certifications (ROHS3, MSL 1) are identical.

OP282GSZ (Analog Devices Inc.)

The OP282GSZ is a cross-manufacturer substitute from Analog Devices Inc. with enhanced electrical performance characteristics. It provides superior input bias current (3 pA versus 30 pA), lower input offset voltage (200 µV versus 3 mV), higher slew rate (9V/µs versus 3.5V/µs), and expanded gain bandwidth product (4 MHz versus 1 MHz). The supply voltage range is extended (9V to 36V versus 10V to 30V), and operating temperature range is wider (-40°C to 85°C versus 0°C to 70°C). However, output current per channel is reduced to 10 mA. This substitute is appropriate for applications requiring improved precision and dynamic performance, provided the 10 mA output current limitation is acceptable. All compliance requirements are met.

Selection Basis:

• Direct Replacement: TL062CDR for functional equivalence with Active status
• Performance Enhancement: OP282GSZ for improved precision and extended operating range, subject to output current verification

Both substitutes maintain RoHS3 compliance and MSL 1 rating, ensuring environmental and moisture handling compatibility with the original TL062CPSR.

Frequently Asked Questions (FAQ)

Q: Can TL062CDR be used as a direct pin-for-pin replacement for TL062CPSR?

A: Yes. Both devices are dual J-FET operational amplifiers in 8-SOIC packages with identical electrical specifications. Pin configuration and functional behavior are equivalent. The primary difference is physical package width (3.90mm versus 5.30mm), which does not affect electrical compatibility but may require PCB layout adjustment.

Q: What is the key limitation of OP282GSZ as a substitute?

A: The OP282GSZ provides enhanced performance in most parameters but reduces output current per channel from 20 mA to 10 mA. Applications requiring output currents exceeding 10 mA per channel must use TL062CPSR or TL062CDR.

Q: Are there temperature range considerations when substituting with OP282GSZ?

A: The TL062CPSR operates from 0°C to 70°C, while OP282GSZ operates from -40°C to 85°C. If the application requires operation below 0°C or above 70°C, OP282GSZ provides extended capability. For standard 0°C to 70°C applications, both are suitable.

Q: Does packaging width affect circuit performance?

A: No. The difference between 5.30mm and 3.90mm package widths is purely physical. Electrical performance and functional behavior are unaffected. PCB layout and routing may require adjustment to accommodate the narrower package.

Q: Are both substitutes RoHS3 compliant?

A: Yes. TL062CDR and OP282GSZ are both ROHS3 compliant with MSL 1 rating, matching the original TL062CPSR compliance status.

Q: Which substitute should be selected for new designs?

A: TL062CDR is recommended for new designs requiring direct functional equivalence with Active product status. OP282GSZ is recommended if enhanced precision (lower input offset voltage and bias current) and extended operating range are required, provided the 10 mA output current limit is acceptable.

Q: What is the significance of Last Time Buy status for TL062CPSR?

A: Last Time Buy indicates the manufacturer has discontinued production. Existing inventory is available but will not be replenished. For long-term supply security, transition to TL062CDR (Active status) or OP282GSZ is recommended.
