Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP6V71UT-E/OT are identified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Package compatibility: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Output configuration: Rail-to-Rail
• Number of circuits: Single circuit
• Supply voltage range: Minimum 2V to maximum 5.5V
• Operating temperature range: Minimum -40°C
• Input bias current: 1 pA maximum
• RoHS3 compliance and REACH unaffected status

The identified substitute parts (OPA336N/250 and OPA336N/3K) maintain mechanical compatibility through identical package specifications and surface mount configuration. Both substitute parts operate within the specified supply voltage range and temperature parameters. However, electrical performance characteristics differ in slew rate, gain bandwidth product, input offset voltage, supply current, and output current specifications.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: All listed parts maintain ROHS3 compliance and REACH unaffected designation, meeting current environmental and regulatory requirements for electronic component procurement.

Product Status: The MCP6V71UT-E/OT and both substitute parts (OPA336N/250 and OPA336N/3K) maintain active product status with manufacturers, ensuring continued availability and support.

Packaging and Mounting Compatibility: All parts utilize identical SOT-23-5 package specifications (SC-74A, SOT-753) with surface mount configuration, enabling direct mechanical substitution on printed circuit boards without layout modifications.

Supply Voltage Compatibility: The substitute parts operate at a minimum supply voltage of 2.3V compared to the main part's 2V minimum. Applications requiring operation below 2.3V cannot use OPA336N/250 or OPA336N/3K as direct substitutes. Both substitute parts maintain the 5.5V maximum supply voltage specification.

Temperature Range Consideration: The MCP6V71UT-E/OT operates to 125°C maximum, while substitute parts operate to 85°C maximum. Applications requiring operation above 85°C cannot use OPA336N/250 or OPA336N/3K as direct substitutes.

Electrical Performance Differences: Substitute parts exhibit lower slew rate (0.03V/µs versus 1V/µs), reduced gain bandwidth product (100 kHz versus 2 MHz), higher input offset voltage (60µV versus 8µV), lower supply current (20µA versus 170µA), and reduced output current capability (5mA versus 26mA). These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can OPA336N/250 and OPA336N/3K be used interchangeably with MCP6V71UT-E/OT?

A: Mechanical substitution is possible due to identical SOT-23-5 packaging and surface mount configuration. However, electrical performance differs significantly. The substitute parts operate at lower slew rates, reduced bandwidth, and higher input offset voltage. Application-specific circuit analysis is required to determine functional equivalence.

Q: What is the difference between OPA336N/250 and OPA336N/3K?

A: Both parts are identical in electrical specifications and package configuration. The designation difference reflects packaging quantity: OPA336N/250 indicates 250-unit tape and reel packaging, while OPA336N/3K indicates 3000-unit tape and reel packaging. Selection depends on procurement volume requirements.

Q: Are there supply voltage limitations when substituting?

A: Yes. The MCP6V71UT-E/OT operates at 2V minimum supply voltage, while OPA336N/250 and OPA336N/3K require 2.3V minimum. Applications operating below 2.3V cannot use the substitute parts.

Q: What is the maximum operating temperature for substitute parts?

A: OPA336N/250 and OPA336N/3K operate to 85°C maximum, compared to 125°C for the MCP6V71UT-E/OT. Applications requiring operation above 85°C cannot use these substitute parts.

Q: Do all parts meet current environmental compliance standards?

A: Yes. The MCP6V71UT-E/OT, OPA336N/250, and OPA336N/3K all maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What are the key electrical differences between the main part and substitutes?

A: The MCP6V71UT-E/OT is classified as a zero-drift amplifier with 1V/µs slew rate and 2MHz gain bandwidth product. The substitute parts are general-purpose amplifiers with 0.03V/µs slew rate and 100kHz gain bandwidth product. The main part also provides lower input offset voltage (8µV versus 60µV) and higher output current capability (26mA versus 5mA).

Q: Is PCB layout modification required for substitution?

A: No. All parts use identical SOT-23-5 package specifications, eliminating the need for PCB layout changes. Direct pin-for-pin substitution is mechanically feasible.
