Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP6293-E/SN are identified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Secondary Electrical Compatibility Parameters:

• Slew Rate: 7 V/µs (primary specification)
• Gain Bandwidth Product: 10 MHz (primary specification)
• Current - Input Bias: 1 pA (primary specification)
• Voltage - Input Offset: 3 mV (primary specification)
• Current - Supply: 1 mA (primary specification)
• Current - Output / Channel: 25 mA (primary specification)
• Voltage - Supply Span: 2.4 V to 6 V (primary specification)
• Operating Temperature: -40°C to 125°C (primary specification)

Substitute parts must maintain compatibility within the specified electrical performance envelope and support the same supply voltage range and temperature operating window. All identified substitutes share identical package geometry and surface mount characteristics, enabling direct PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

TLV2620IDR (Texas Instruments)

The TLV2620IDR is a direct substitute for the MCP6293-E/SN in applications requiring identical slew rate (7 V/µs) and extended temperature operation (-40°C to 125°C). This device matches the primary electrical specifications and maintains ROHS3 compliance with unlimited moisture sensitivity rating. The TLV2620IDR is classified as Last Time Buy product status. Supply voltage range compatibility is limited to 2.7 V to 5.5 V, which excludes the MCP6293-E/SN's lower 2.4 V minimum specification. Output current capability is slightly higher at 28 mA versus 25 mA. This substitute is suitable for designs operating within the 2.7 V to 5.5 V supply envelope.

TLV2621IDR (Texas Instruments)

The TLV2621IDR provides equivalent electrical performance to the TLV2620IDR with identical slew rate, gain bandwidth product, and temperature range specifications. This device maintains ROHS3 compliance and unlimited moisture sensitivity rating. Product status is Last Time Buy. Supply voltage range is 2.7 V to 5.5 V, matching the TLV2620IDR limitation. Output current is 28 mA. The TLV2621IDR is functionally interchangeable with the TLV2620IDR for the specified parameter set.

OPA338UA (Burr Brown)

The OPA338UA is a general-purpose rail-to-rail amplifier in 8-SOIC packaging with lower slew rate (4.6 V/µs) and higher gain bandwidth product (12.5 MHz) compared to the MCP6293-E/SN. Input bias current is significantly lower at 0.2 pA, and input offset voltage is reduced to 0.5 mV. Supply current is lower at 0.525 mA. Operating temperature range is limited to -40°C to 85°C, which excludes the extended 125°C upper specification of the MCP6293-E/SN. Supply voltage range is 2.7 V to 5.5 V. This substitute is applicable only for designs with temperature requirements not exceeding 85°C and supply voltages within the 2.7 V to 5.5 V range.

Frequently Asked Questions (FAQ)

Q: Can the OPA338UA replace the MCP6293-E/SN in all applications?

A: The OPA338UA is not a universal substitute. While it shares the same package type and general-purpose amplifier classification, it has a maximum operating temperature of 85°C, which is 40°C lower than the MCP6293-E/SN specification of 125°C. Use the OPA338UA only in applications with maximum operating temperatures not exceeding 85°C.

Q: What is the primary difference between TLV2620IDR and TLV2621IDR?

A: Both devices share identical electrical specifications including slew rate (7 V/µs), gain bandwidth product (11 MHz), input bias current (2 pA), input offset voltage (0.25 µV), supply current (0.8 mA), and output current (28 mA). They are functionally equivalent for the specified parameter set.

Q: Are all substitute parts compatible with the MCP6293-E/SN's 2.4 V minimum supply voltage?

A: No. The OPA338UA, TLV2620IDR, and TLV2621IDR all specify a minimum supply voltage of 2.7 V, which is 0.3 V higher than the MCP6293-E/SN. Designs requiring operation at 2.4 V supply voltage cannot use these substitutes.

Q: Do all substitute parts maintain RoHS3 compliance?

A: The TLV2620IDR and TLV2621IDR are explicitly RoHS3 compliant with unlimited moisture sensitivity rating. The OPA338UA compliance status is not specified in the provided data.

Q: What is the impact of different slew rates on circuit performance?

A: The MCP6293-E/SN and TLV2620IDR/TLV2621IDR share a slew rate of 7 V/µs. The OPA338UA has a lower slew rate of 4.6 V/µs, which may affect high-frequency signal fidelity and transient response characteristics. Applications sensitive to slew rate performance should use devices with matching 7 V/µs specification.

Q: Can the MCP6293-E/SN be used in place of the TLV2620IDR?

A: The MCP6293-E/SN can substitute for the TLV2620IDR in applications where the extended supply voltage range (2.4 V to 6 V) of the MCP6293-E/SN is beneficial. Both devices share identical slew rate (7 V/µs) and extended temperature operation (-40°C to 125°C). The MCP6293-E/SN provides broader supply voltage compatibility.

Q: Are there packaging differences between these devices?

A: All four devices use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. PCB layout and footprint compatibility is maintained across all substitutes.

Q: What is the significance of "Last Time Buy" product status for TLV2620IDR and TLV2621IDR?

A: Last Time Buy status indicates these devices are in end-of-life phase with limited future availability. Designs using these substitutes should consider long-term supply chain implications and evaluate the Active status MCP6293-E/SN as a primary component choice for new designs.
