EL8201ISZ Equivalent & Substitute Parts

Part Overview

The EL8201ISZ is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation, configured as a dual-circuit (2-channel) rail-to-rail amplifier in an 8-SOIC surface-mount package. This device is classified as obsolete, indicating that direct procurement from the original manufacturer is no longer available through standard distribution channels. Identifying equivalent and substitute parts is necessary to maintain design continuity, support production requirements, and ensure long-term component availability for applications currently utilizing the EL8201ISZ.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL8201ISZ is determined by the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Package Compatibility: 8-SOIC form factor with identical 0.154" (3.90mm) width
• Circuit Configuration: Dual-circuit (2-channel) amplifier topology
• Output Architecture: Rail-to-rail output capability
• Supply Voltage Range: Minimum 3V to maximum 5V operation
• Operating Temperature Range: -40°C to 85°C
• Mounting Technology: Surface-mount configuration
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute parts identified (OPA2337UA, OPA2337UA/2K5, OPA2338UA, OPA2338UA/2K5) satisfy all primary substitution criteria. These Texas Instruments MicroAmplifier™ series devices are manufactured in the same 8-SOIC package, provide dual-circuit rail-to-rail amplification, and operate within the specified supply voltage and temperature ranges. All substitute parts maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EL8201ISZ is classified as obsolete, while all identified substitute parts (OPA2337UA, OPA2337UA/2K5, OPA2338UA, OPA2338UA/2K5) maintain active product status from Texas Instruments. Active status ensures ongoing manufacturing support, availability through distribution channels, and continued technical documentation updates.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original EL8201ISZ. This alignment ensures compatibility with current procurement and environmental regulations.

Packaging Options: Substitute parts are available in two packaging configurations: Tube (OPA2337UA, OPA2338UA) and Tape & Reel (OPA2337UA/2K5, OPA2338UA/2K5). Selection between these packaging options depends on production volume and assembly process requirements. Tape & Reel packaging is typically specified for high-volume automated assembly operations, while Tube packaging is suitable for lower-volume or manual assembly scenarios.

Performance Trade-offs: The substitute parts exhibit lower slew rates, reduced gain-bandwidth products, and lower output current capabilities compared to the EL8201ISZ. Applications requiring the original device's high-speed performance characteristics (200 V/µs slew rate, 100 MHz gain-bandwidth product, 65 mA output current) must evaluate whether the reduced performance specifications of substitute parts are acceptable for the intended circuit function. The OPA2338UA and OPA2338UA/2K5 variants provide higher performance than the OPA2337UA variants and should be prioritized when higher bandwidth or slew rate is required within the substitute part family.

Frequently Asked Questions (FAQ)

Q: Can the OPA2337UA and OPA2338UA be used interchangeably with the EL8201ISZ?

A: Both OPA2337UA and OPA2338UA are functionally compatible substitutes for the EL8201ISZ in terms of package, pin configuration, and basic operational characteristics. However, they differ in performance specifications. The OPA2337UA provides 3 MHz gain-bandwidth product and 1.2 V/µs slew rate, while the OPA2338UA provides 12.5 MHz gain-bandwidth product and 4.6 V/µs slew rate. Selection between these variants depends on the bandwidth and slew rate requirements of the specific application.

Q: What is the difference between OPA2337UA and OPA2337UA/2K5?

A: The OPA2337UA and OPA2337UA/2K5 are electrically identical devices. The primary difference is packaging: OPA2337UA is supplied in Tube packaging, while OPA2337UA/2K5 is supplied in Tape & Reel (TR) packaging. The "/2K5" designation indicates the tape and reel configuration. Selection depends on production volume and assembly process requirements.

Q: Are the substitute parts pin-compatible with the EL8201ISZ?

A: Yes. All substitute parts are configured in the 8-SOIC package with identical pin assignments and spacing (0.154" width, 3.90mm). Direct board-level substitution is possible without PCB redesign.

Q: Do the substitute parts operate within the same supply voltage range as the EL8201ISZ?

A: The EL8201ISZ operates from 3V to 5V. The substitute parts operate from 2.7V to 5.5V, providing a wider supply voltage range. This expanded range ensures compatibility with the original specification and provides additional design flexibility for lower-voltage applications.

Q: What are the key performance differences between the EL8201ISZ and the substitute parts?

A: The EL8201ISZ exhibits significantly higher performance in three areas: slew rate (200 V/µs versus 1.2-4.6 V/µs), gain-bandwidth product (100 MHz versus 3-12.5 MHz), and output current per channel (65 mA versus 9 mA). Applications sensitive to these parameters must evaluate whether the reduced performance of substitute parts is acceptable. The OPA2338UA variants provide the highest performance among the substitutes and should be considered first when performance is critical.

Q: What is the input bias current difference between the EL8201ISZ and substitute parts?

A: The EL8201ISZ has an input bias current of 1.6 µA, while all substitute parts have an input bias current of 0.2 pA. This represents a significant reduction in input bias current with the substitute parts, which may improve performance in high-impedance input circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (OPA2337UA, OPA2337UA/2K5, OPA2338UA, OPA2338UA/2K5) are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of the original EL8201ISZ.

Q: Which substitute part should be selected for new designs?

A: For new designs, the OPA2338UA or OPA2338UA/2K5 are recommended as they provide the highest performance specifications among the substitute parts (12.5 MHz gain-bandwidth product and 4.6 V/µs slew rate) while maintaining full compatibility with the EL8201ISZ package and pin configuration. Packaging selection (Tube versus Tape & Reel) should be based on production volume and assembly process requirements.
