Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPA336MDBVREP is determined by strict adherence to the following criteria:

Primary Compatibility Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: SC-74A, SOT-753
• Supplier Device Package: SOT-23-5
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Parameter Ranges for Substitution:

• Voltage - Supply Span (Min): 2.3 V or lower
• Voltage - Supply Span (Max): 5.5 V or higher
• Operating Temperature: Must encompass or match -55°C ~ 125°C range

The three substitute parts identified—MCP606T-I/OT, MCP6286T-E/OT, and MCP6421T-E/OT—satisfy all primary compatibility requirements and operate within acceptable supply voltage and temperature ranges. Variations in slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel are permissible within the general-purpose amplifier category, provided the physical package and electrical interface remain compatible.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active production status and ROHS3 compliance, ensuring regulatory alignment with the OPA336MDBVREP. Selection among substitutes is based on specific application requirements and operational constraints:

MCP606T-I/OT is suitable for applications requiring moderate performance enhancement over the OPA336MDBVREP. This part offers improved slew rate (0.08 V/µs versus 0.03 V/µs) and higher gain bandwidth product (155 kHz versus 100 kHz), with reduced input offset voltage (250 µV versus 500 µV). Supply current is marginally lower at 18.7 µA. However, the maximum operating temperature is limited to 85°C, which restricts use in extended temperature applications. Moisture sensitivity is improved to MSL 1 (Unlimited).

MCP6286T-E/OT provides significantly enhanced performance characteristics, including substantially higher slew rate (2 V/µs) and gain bandwidth product (3.5 MHz). This part accommodates the full operating temperature range (-40°C ~ 125°C) and maintains the 5.5 V maximum supply voltage. Increased supply current (540 µA) and input offset voltage (1.5 mV) reflect the higher performance tier. This substitute is appropriate for applications demanding faster signal processing and wider bandwidth.

MCP6421T-E/OT is optimized for ultra-low power consumption, with supply current of only 4.4 µA—substantially lower than the OPA336MDBVREP at 23 µA. This part supports the full operating temperature range (-40°C ~ 125°C) and extends the minimum supply voltage to 1.8 V, enabling operation in battery-powered and energy-constrained applications. Slew rate (0.05 V/µs) and gain bandwidth product (90 kHz) remain comparable to the original part. Moisture sensitivity is improved to MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can MCP606T-I/OT be used in applications requiring operation below -40°C?

A: No. The MCP606T-I/OT operating temperature range is -40°C ~ 85°C. For applications requiring operation at -55°C, the OPA336MDBVREP, MCP6286T-E/OT, or MCP6421T-E/OT must be used.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences between the OPA336MDBVREP and substitute parts?

A: The OPA336MDBVREP has MSL 2 (1 Year), indicating a one-year shelf life limit after moisture exposure. All three substitute parts have MSL 1 (Unlimited), providing indefinite shelf life. This affects storage, handling, and supply chain management protocols.

Q: Are all substitute parts pin-compatible with the OPA336MDBVREP?

A: Yes. All substitute parts use the SC-74A, SOT-753 package with SOT-23-5 supplier device package configuration, ensuring identical pinout and PCB footprint compatibility.

Q: Which substitute part is recommended for battery-powered applications?

A: The MCP6421T-E/OT is optimized for battery-powered designs, offering the lowest supply current at 4.4 µA and the lowest minimum supply voltage at 1.8 V.

Q: Can MCP6286T-E/OT be used as a direct replacement in all OPA336MDBVREP applications?

A: MCP6286T-E/OT is physically and electrically compatible but exhibits significantly different performance characteristics, including higher slew rate, gain bandwidth product, supply current, and input offset voltage. Application-specific circuit analysis is required to confirm suitability.

Q: What is the inventory availability status of substitute parts?

A: MCP6421T-E/OT has the highest inventory at 93,070 units. MCP606T-I/OT has 55,400 units available. MCP6286T-E/OT has 6,400 units available. The OPA336MDBVREP has 757 units in stock.

Q: Are all parts compliant with REACH and RoHS regulations?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
