AS358GTR-E1 Equivalent & Substitute Parts

Part Overview

The AS358GTR-E1 is a general-purpose operational amplifier manufactured by Diodes Incorporated, configured as a dual-channel integrated circuit in 8-TSSOP surface-mount packaging. This device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when the main part becomes unavailable, when inventory constraints require alternative sourcing, or when application requirements align with alternative amplifier topologies that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AS358GTR-E1 are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Dual-channel configuration (2 circuits)
• 8-TSSOP surface-mount package with 0.173" width (4.40mm)
• Operating temperature range of -40°C to 85°C
• Supply voltage overlap within the application range
• Output current capability of at least 40 mA per channel
• ROHS3 compliance and Active product status

Substitution Logic: The RC4560IPWR and TL082IPWR are qualified as substitute parts because they maintain identical package geometry, dual-channel architecture, and compatible operating temperature specifications. Both devices are surface-mount 8-TSSOP components with Active product status and ROHS3 compliance. The substitutes differ in amplifier topology (Audio and J-FET respectively) and specific electrical characteristics, but these differences do not preclude functional substitution when the application requirements align with the substitute device specifications.

Parameter Comparison

Engineering Selection Recommendations

AS358GTR-E1 Primary Selection: The AS358GTR-E1 remains the primary component choice when available. This device is manufactured by Diodes Incorporated, maintains Active product status, and is ROHS3 compliant. The general-purpose amplifier topology provides broad application compatibility with a wide supply voltage range (3 V to 36 V) and adequate output current capability (40 mA per channel).

RC4560IPWR Substitution: The RC4560IPWR is a qualified substitute when the AS358GTR-E1 is unavailable. This Texas Instruments audio amplifier maintains identical package geometry and dual-channel configuration. The RC4560IPWR is ROHS3 compliant and Active status. The supply voltage range (4 V to 32 V) overlaps substantially with the AS358GTR-E1 application envelope. Output current capability (50 mA per channel) exceeds the AS358GTR-E1 specification. The RC4560IPWR exhibits superior input offset voltage (500 µV versus 2 mV), which may provide performance advantages in precision applications.

TL082IPWR Substitution: The TL082IPWR is a qualified substitute for applications requiring J-FET input characteristics. This Texas Instruments device maintains identical package geometry and dual-channel configuration. The TL082IPWR is ROHS3 compliant and Active status. The minimum supply voltage requirement (10 V) is higher than the AS358GTR-E1 (3 V minimum), restricting use to applications with adequate supply voltage headroom. Output current capability (10 mA per channel) is lower than the AS358GTR-E1 specification and may not satisfy high-current output requirements. The J-FET input stage provides extremely low input bias current (30 pA), which is advantageous for high-impedance signal sources.

Frequently Asked Questions (FAQ)

Q: Can the RC4560IPWR directly replace the AS358GTR-E1 in all applications?

A: The RC4560IPWR is mechanically and functionally compatible with the AS358GTR-E1 due to identical 8-TSSOP packaging and dual-channel configuration. However, the RC4560IPWR is specified as an audio amplifier, whereas the AS358GTR-E1 is a general-purpose amplifier. Substitution is valid when the application requirements align with audio amplifier specifications and the supply voltage range (4 V to 32 V) is compatible with the circuit design.

Q: What are the supply voltage constraints for each substitute?

A: The AS358GTR-E1 operates from 3 V to 36 V. The RC4560IPWR operates from 4 V to 32 V, which covers most applications but excludes designs requiring 3 V minimum supply. The TL082IPWR operates from 10 V to 30 V, which restricts use to higher-voltage applications and excludes low-voltage designs.

Q: Which substitute provides the lowest input bias current?

A: The TL082IPWR provides the lowest input bias current at 30 pA, compared to 20 nA for the AS358GTR-E1 and 40 nA for the RC4560IPWR. The J-FET input stage of the TL082IPWR is advantageous for high-impedance signal conditioning applications.

Q: Are all three devices available in Tape & Reel packaging?

A: Yes. The AS358GTR-E1, RC4560IPWR, and TL082IPWR are all supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the output current capability difference between the main part and substitutes?

A: The AS358GTR-E1 provides 40 mA per channel. The RC4560IPWR provides 50 mA per channel, exceeding the main part specification. The TL082IPWR provides 10 mA per channel, which is lower and may not satisfy applications requiring the full 40 mA output current of the AS358GTR-E1.

Q: Do all devices meet the same compliance standards?

A: Yes. The AS358GTR-E1, RC4560IPWR, and TL082IPWR are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8542.33.0001.

Q: What is the operating temperature range for each device?

A: All three devices operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility across the specified operating envelope.
