MAX4230AXK-T Equivalent & Substitute Parts

Part Overview

The MAX4230AXK-T is a general purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, housed in a 5-TSSOP (SC-70-5, SOT-353) surface mount package. This device features rail-to-rail output capability and is designed for low-power, single-circuit amplification applications across a 2.7V to 5.5V supply range.

The MAX4230AXK-T is classified as obsolete. Locating equivalent and substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity. Substitute components must maintain electrical compatibility across critical parameters including supply voltage range, output type, package configuration, and operating temperature specifications.

Substitute Part Grouping Explanation

Substitute parts for the MAX4230AXK-T are identified based on strict electrical and mechanical compatibility criteria. The substitution logic is structured as follows:

Primary Substitution Criteria:

• Package / Case: 5-TSSOP, SC-70-5, SOT-353 (identical physical form factor)
• Mounting Type: Surface Mount (identical assembly method)
• Amplifier Type: General Purpose (functional equivalence)
• Number of Circuits: 1 (single amplifier per package)
• Output Type: Rail-to-Rail (output swing capability)
• Operating Temperature: -40°C to 125°C (temperature range compatibility)
• Supply Voltage Range: Minimum 2.7V, Maximum 5.5V (operational envelope)

Secondary Compatibility Parameters:

• Gain Bandwidth Product: 10 MHz (frequency response specification)
• RoHS3 Compliance and MSL Level 1 (regulatory and handling requirements)

Substitute parts are grouped into two categories:

Category 1: Direct Manufacturer Equivalent MAX4230AXK+T is an identical electrical specification variant from the same manufacturer (Analog Devices Inc./Maxim Integrated) with active product status. This part maintains all electrical parameters of the original MAX4230AXK-T and differs only in packaging format (Cut Tape & Digi-Reel versus original packaging).

Category 2: Cross-Manufacturer Substitute OPA316IDCKR and OPA316IDCKT are Texas Instruments general purpose operational amplifiers in identical SC-70-5 packages. These parts meet the core substitution criteria of package compatibility, rail-to-rail output, single-circuit configuration, and temperature range. Both parts maintain active product status and ROHS3 compliance.

Engineering Selection Recommendations

MAX4230AXK+T Selection Rationale: The MAX4230AXK+T is the preferred direct substitute for the obsolete MAX4230AXK-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications across all measured parameters. The MAX4230AXK+T holds active product status, ensuring long-term availability and supply chain continuity. This part is recommended as the primary replacement option for new production and design updates.

OPA316IDCKR and OPA316IDCKT Selection Rationale: The OPA316IDCKR and OPA316IDCKT are cross-manufacturer substitutes from Texas Instruments. Both parts satisfy core substitution requirements: identical SC-70-5 package configuration, rail-to-rail output capability, single-circuit topology, and -40°C to 125°C operating temperature range. Both maintain active product status and ROHS3 compliance.

Electrical parameter differences exist between the MAX4230AXK-T and OPA316 series. The OPA316 devices exhibit lower input bias current (5 pA versus 50 pA), lower input offset voltage (500 µV versus 850 µV), and lower supply current (400 µA versus 1.2 mA). The OPA316 series supports a lower minimum supply voltage (1.8V versus 2.7V) and features a lower slew rate (6 V/µs versus 10 V/µs). These differences are within the functional envelope of general purpose amplifier applications and do not preclude substitution in circuits designed for the MAX4230AXK-T.

Both OPA316 variants (OPA316IDCKR and OPA316IDCKT) are electrically identical and differ only in packaging format (Tape & Reel variants).

Frequently Asked Questions (FAQ)

Q: Can the MAX4230AXK+T be used as a direct replacement for the MAX4230AXK-T?

A: Yes. The MAX4230AXK+T is electrically and functionally identical to the MAX4230AXK-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical specifications across all electrical parameters, package configuration, and operating conditions. The MAX4230AXK+T is the recommended primary substitute due to its active product status.

Q: What are the key differences between the MAX4230AXK-T and the OPA316IDCKR/OPA316IDCKT?

A: The OPA316 series from Texas Instruments differs from the MAX4230AXK-T in the following electrical parameters: input bias current (5 pA versus 50 pA), input offset voltage (500 µV versus 850 µV), supply current (400 µA versus 1.2 mA), minimum supply voltage (1.8V versus 2.7V), and slew rate (6 V/µs versus 10 V/µs). Package configuration, output type, gain bandwidth product, operating temperature range, and mounting method are identical. These electrical differences do not prevent substitution in general purpose amplifier applications.

Q: Are the OPA316IDCKR and OPA316IDCKT interchangeable?

A: Yes. The OPA316IDCKR and OPA316IDCKT are electrically identical. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications. The designations indicate different packaging formats (Tape & Reel variants), not electrical differences.

Q: Does the SC-70-5 package ensure mechanical compatibility across all substitute parts?

A: Yes. All substitute parts listed (MAX4230AXK+T, OPA316IDCKR, OPA316IDCKT) are housed in the 5-TSSOP SC-70-5 SOT-353 package. This identical package configuration ensures mechanical compatibility with existing printed circuit board layouts, assembly equipment, and socket configurations designed for the MAX4230AXK-T.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The MAX4230AXK+T, OPA316IDCKR, and OPA316IDCKT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). These compliance certifications match the original MAX4230AXK-T specifications.

Q: What is the supply voltage compatibility range for substitute parts?

A: The MAX4230AXK-T and MAX4230AXK+T operate across a 2.7V to 5.5V supply range. The OPA316IDCKR and OPA316IDCKT support a wider range of 1.8V to 5.5V. All substitute parts are compatible with the 2.7V to 5.5V envelope of the original part. The OPA316 series provides additional flexibility for lower voltage applications.

Q: Can the OPA316 series be used in circuits originally designed for the MAX4230AXK-T?

A: The OPA316 series can be substituted in general purpose amplifier circuits designed for the MAX4230AXK-T. The identical package, rail-to-rail output capability, single-circuit configuration, and operating temperature range ensure mechanical and functional compatibility. Circuit designers should evaluate the electrical parameter differences (input bias current, input offset voltage, slew rate, and supply current) to confirm suitability for specific application requirements.
