Substitute Part Grouping Explanation

Substitution of the OP293ES-REEL is determined by compatibility across the following critical parameters: package type (8-SOIC surface mount), amplifier topology (general-purpose operational amplifier), supply voltage range, operating temperature range, and output current capability. The OP293ES-REEL is a single-circuit device; therefore, direct equivalents must maintain this configuration. Substitute parts may feature enhanced performance characteristics such as higher slew rates, increased gain bandwidth products, or improved input offset voltage specifications, provided they operate within compatible supply voltage and temperature ranges and maintain the same physical package footprint.

The substitution logic recognizes two categories:

Direct Equivalent: OP293ESZ-REEL maintains identical electrical specifications and differs only in packaging format (Tape & Reel versus bulk reel configuration) and product status (Active versus Obsolete).

Functional Substitutes: LM258ADT, LM258DT, LM2904AYDT, LM2904DT, LM2904YDT, LM358ADT, LM358DT, MC33078DT, and MC33078YDT provide operational amplifier functionality in the same 8-SOIC package with compatible supply voltage ranges. These parts feature dual-circuit configurations (2 circuits per package) and enhanced performance parameters including higher slew rates and gain bandwidth products. Selection depends on application requirements for circuit count, bandwidth, and temperature operating range.

Engineering Selection Recommendations

Direct Equivalent Selection:

OP293ESZ-REEL is the recommended direct equivalent for OP293ES-REEL. This part maintains identical electrical specifications and mechanical package configuration. The primary distinction is product status: OP293ESZ-REEL is Active and available in Tape & Reel packaging format, whereas OP293ES-REEL is Obsolete. OP293ESZ-REEL is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new production.

Substitute Part Selection Based on Application Requirements:

For applications requiring extended temperature operation (-40°C to 125°C) with dual-circuit capability and active product status, LM2904AYDT is suitable. This part is AEC-Q100 qualified and ROHS3 compliant, offering 40 mA output current per channel and 1.1 MHz gain bandwidth product.

For applications with relaxed temperature requirements (0°C to 70°C) and automotive qualification, LM358ADT provides dual-circuit functionality with 1.1 MHz gain bandwidth product and 40 mA output current per channel. This part is AEC-Q100 qualified and ROHS3 compliant.

For applications requiring high-speed operation (7 V/µs slew rate, 15 MHz gain bandwidth product), MC33078DT and MC33078YDT are suitable. Both parts are AEC-Q100 qualified, ROHS3 compliant, and maintain dual-circuit configuration with 37 mA output current per channel. Minimum supply voltage requirement is 5 V.

Parts designated "Not For New Designs" (LM2904DT) or "Obsolete" (LM358DT) should not be selected for new production designs.

Frequently Asked Questions (FAQ)

Q: Can OP293ES-REEL be directly replaced with OP293ESZ-REEL?

A: Yes. OP293ESZ-REEL is the direct equivalent of OP293ES-REEL. Both parts maintain identical electrical specifications, operating temperature range (-40°C to 125°C), supply voltage range (1.7 V to 36 V), and 8-SOIC package configuration. The primary difference is packaging format (Tape & Reel) and product status (Active versus Obsolete). OP293ESZ-REEL is recommended for new production.

Q: Why do substitute parts like LM258ADT have different circuit counts?

A: The OP293ES-REEL contains a single operational amplifier circuit, while LM258ADT and similar substitutes contain two operational amplifier circuits in the same 8-SOIC package. Applications requiring only one amplifier circuit can utilize one of the two available circuits in dual-circuit devices. The second circuit remains available for additional signal processing functions or can be configured as a unity-gain buffer for impedance isolation.

Q: What is the minimum supply voltage requirement for MC33078DT?

A: MC33078DT requires a minimum supply voltage of 5 V, compared to 1.7 V for OP293ES-REEL. Applications operating at supply voltages below 5 V cannot use MC33078DT as a substitute. For low-voltage applications, LM2904AYDT or LM258ADT are appropriate alternatives, both supporting 3 V minimum supply voltage.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected. OP293ES-REEL, being an obsolete part, does not carry current ROHS3 compliance documentation. OP293ESZ-REEL is the recommended equivalent for applications requiring ROHS3 compliance.

Q: What is the significance of AEC-Q100 qualification?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. Parts bearing this qualification (LM2904AYDT, LM358ADT, MC33078DT, MC33078YDT) are suitable for automotive applications and high-reliability industrial applications. Non-qualified parts may be suitable for general-purpose applications with less stringent reliability requirements.

Q: Can OP293ES-REEL be used in applications requiring operation above 105°C?

A: Yes. OP293ES-REEL operates to 125°C maximum, exceeding the 105°C limit of LM258ADT and MC33078DT. For applications requiring extended temperature operation to 125°C, LM2904AYDT, LM2904DT, or LM2904YDT are suitable substitutes, all supporting -40°C to 125°C operating range.

Q: What is the difference between LM2904AYDT and LM2904YDT?

A: Both parts are manufactured by STMicroelectronics and feature dual-circuit configuration in 8-SOIC package. LM2904AYDT provides 1.1 MHz gain bandwidth product with 40 mA output current per channel. LM2904YDT provides 700 kHz gain bandwidth product with 30 mA output current per channel. Selection depends on application bandwidth requirements and output current demands.

Q: Is the 8-SOIC package footprint identical across all listed parts?

A: Yes. All parts are housed in 8-SOIC package with 0.154" (3.90 mm) width. Physical footprint and pin configuration are identical, enabling direct PCB layout compatibility. Electrical pin assignments follow standard operational amplifier conventions across all listed parts.
