SE5230DG Equivalent & Substitute Parts

Part Overview

The SE5230DG is a general purpose operational amplifier manufactured by onsemi, housed in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The SE5230DG features rail-to-rail output capability with a 600 kHz gain bandwidth product and operates across a 1.8 V to 15 V supply range. Due to its obsolete status, identification of functionally equivalent substitute components is necessary for ongoing system support, maintenance, and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE5230DG is determined by alignment across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier type classification (General Purpose)
• Number of circuits per package (1 circuit)
• Package form factor and pin compatibility (8-SOIC surface mount)
• Slew rate performance (0.25 V/µs)
• Gain bandwidth product (600 kHz)

Electrical Operating Range Compatibility:

• Supply voltage span must encompass or exceed the original specification
• Input bias current and input offset voltage characteristics
• Output current capability per channel
• Operating temperature range suitability for the application

The OP07CS8#PBF from Analog Devices Inc. satisfies these substitution criteria through matching slew rate and gain bandwidth product specifications, identical package geometry, and compatible surface mount mounting technology. The OP07CS8#PBF operates across a 6 V to 36 V supply range, which encompasses the SE5230DG operating window. Both devices maintain MSL 1 moisture sensitivity classification and REACH compliance status.

Engineering Selection Recommendations

SE5230DG (Primary Part - Obsolete Status): The SE5230DG is classified as obsolete with no active production. Current inventory availability is limited to existing stock. This part number should not be selected for new designs or long-term production commitments.

OP07CS8#PBF (Active Substitute): The OP07CS8#PBF is an active product from Analog Devices Inc. with confirmed inventory availability. This device maintains identical slew rate and gain bandwidth product specifications, ensuring functional equivalence in applications designed for the SE5230DG. The OP07CS8#PBF is RoHS3 compliant and carries REACH compliance certification, meeting current regulatory requirements. The substitute part operates across a wider supply voltage range (6 V to 36 V), providing enhanced flexibility for systems with variable supply conditions. Both devices share identical package geometry and surface mount characteristics, enabling direct PCB layout compatibility.

Compliance Considerations: The OP07CS8#PBF is RoHS3 compliant, whereas the SE5230DG compliance status is not specified. For applications subject to RoHS directives, the OP07CS8#PBF is the appropriate selection. Both parts maintain REACH compliance and carry identical ECCN and HTSUS classifications.

Temperature Range Limitation: The OP07CS8#PBF operates across 0°C to 70°C, which is narrower than the SE5230DG range of -40°C to 125°C. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must evaluate this constraint against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the OP07CS8#PBF directly replace the SE5230DG in existing designs?

A: The OP07CS8#PBF provides functional equivalence through matching slew rate (0.25 V/µs) and gain bandwidth product (600 kHz) specifications. Both devices use identical 8-SOIC package geometry with matching pin assignments. Direct PCB substitution is supported from a physical and electrical standpoint. However, the OP07CS8#PBF operating temperature range (0°C to 70°C) is narrower than the SE5230DG (−40°C to 125°C). Applications operating outside the 0°C to 70°C window require thermal performance verification.

Q: What are the key electrical differences between these parts?

A: The OP07CS8#PBF exhibits superior input bias current (1.8 nA versus 40 nA) and input offset voltage (60 µV versus 400 µV) characteristics. The OP07CS8#PBF supply voltage range (6 V to 36 V) is wider than the SE5230DG (1.8 V to 15 V). These differences indicate the OP07CS8#PBF is suitable for applications where lower input bias current and offset voltage are beneficial, and where supply voltages remain within the 6 V to 36 V window.

Q: Are there packaging differences between these parts?

A: Both the SE5230DG and OP07CS8#PBF use 8-SOIC surface mount packages with identical 0.154" (3.90mm) width specifications. Pin-to-pin compatibility is maintained. The SE5230DG is supplied in standard packaging, while the OP07CS8#PBF is supplied in tube packaging. This difference affects handling and storage procedures but does not impact electrical performance or PCB assembly compatibility.

Q: What is the significance of the obsolete status for the SE5230DG?

A: Obsolete classification indicates onsemi has discontinued production of the SE5230DG. Existing inventory is finite and will not be replenished. For applications requiring long-term component availability and ongoing production support, transition to the active OP07CS8#PBF is necessary. The obsolete status does not affect the performance of existing SE5230DG units already deployed in systems.

Q: How do the input bias current specifications affect circuit design?

A: The OP07CS8#PBF input bias current of 1.8 nA is significantly lower than the SE5230DG specification of 40 nA. Lower input bias current reduces errors in high-impedance input circuits and minimizes offset voltage drift caused by source impedance. Applications with source impedances exceeding 1 MΩ benefit from the OP07CS8#PBF lower bias current specification.

Q: Is the OP07CS8#PBF suitable for low-voltage applications below 6 V?

A: The OP07CS8#PBF minimum supply voltage is 6 V. Applications requiring operation below 6 V cannot use this substitute. The SE5230DG supports operation down to 1.8 V, making it suitable for low-voltage battery-powered systems. For applications requiring sub-6 V operation, alternative substitutes must be evaluated.

Q: What compliance certifications apply to the OP07CS8#PBF?

A: The OP07CS8#PBF is RoHS3 compliant and REACH compliant. Both certifications indicate compliance with current environmental and hazardous substance regulations. The SE5230DG compliance status is not specified in available documentation. For applications subject to RoHS or REACH requirements, the OP07CS8#PBF meets regulatory obligations.
