MCP6293T-E/SN Equivalent & Substitute Parts

Part Overview

The MCP6293T-E/SN is a general-purpose operational amplifier manufactured by Microchip Technology, configured as a single-circuit rail-to-rail output device in 8-SOIC surface mount packaging. This linear amplifier is designed for applications requiring low-power operation with supply voltages between 2.4 V and 6 V across an operating temperature range of -40°C to 125°C. The part is currently in active product status with 961 units in stock.

Substitute parts become necessary when the primary component experiences supply constraints, end-of-life transitions, or when design requirements necessitate alternative electrical characteristics within compatible mechanical and functional parameters. The MCP6293T-E/SN maintains compatibility with substitute devices that share identical package geometry, circuit count, output type, and overlapping electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MCP6293T-E/SN is determined by strict adherence to the following criteria:

Mandatory Compatibility Parameters:

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

Electrical Parameter Ranges for Substitution: Substitute parts must operate within overlapping supply voltage ranges and maintain compatible slew rate, gain bandwidth product, and output current specifications. The MCP6293T-E/SN operates at 2.4 V to 6 V; substitute devices must support at minimum the lower bound of this range or higher, with maximum supply voltage at or above 5.5 V to ensure functional overlap in typical applications.

Identified Substitute Parts:

• OPA338UA (Burr Brown)
• TLV2620IDR (Texas Instruments)
• TLV2621IDR (Texas Instruments)

All three substitute devices share identical package geometry, circuit configuration, and output type. Electrical performance varies within acceptable ranges for general-purpose amplifier applications.

Parameter Comparison

Engineering Selection Recommendations

OPA338UA (Burr Brown): This substitute offers superior input bias current (0.2 pA) and input offset voltage (0.5 µV) compared to the MCP6293T-E/SN, with higher gain bandwidth product (12.5 MHz). However, the maximum operating temperature is limited to 85°C, which restricts use in applications requiring the full -40°C to 125°C range of the primary part. The OPA338UA is suitable for applications operating within -40°C to 85°C where lower input offset voltage is beneficial. Product status is active with 2210 units in stock.

TLV2620IDR (Texas Instruments): This substitute maintains identical slew rate (7 V/µs) and comparable gain bandwidth product (11 MHz) to the MCP6293T-E/SN. Operating temperature range extends to 125°C, matching the primary part. Output current per channel (28 mA) exceeds the primary part specification (25 mA). Supply current is higher at 0.8 mA versus 1 mA. The TLV2620IDR is designated Last Time Buy, indicating limited future availability. ROHS3 compliance is confirmed. This part is suitable for direct substitution in applications requiring full temperature range operation.

TLV2621IDR (Texas Instruments): Electrical specifications are identical to the TLV2620IDR, with matching slew rate (7 V/µs), gain bandwidth product (11 MHz), and operating temperature range (-40°C to 125°C). Output current per channel (28 mA) and supply current (0.8 mA) match the TLV2620IDR. The TLV2621IDR is also designated Last Time Buy. ROHS3 compliance is confirmed. This part provides equivalent substitution capability to the TLV2620IDR with identical electrical performance.

Selection Basis:

• For applications requiring operation above 85°C: TLV2620IDR or TLV2621IDR
• For applications with strict input offset voltage requirements: OPA338UA
• For long-term supply assurance: MCP6293T-E/SN (active status)
• For cost optimization with temperature constraints: OPA338UA

Frequently Asked Questions (FAQ)

Q: Can the OPA338UA replace the MCP6293T-E/SN in all applications?

A: The OPA338UA is mechanically and functionally compatible but has a maximum operating temperature of 85°C. It cannot replace the MCP6293T-E/SN in applications requiring operation above 85°C or across the full -40°C to 125°C range.

Q: What is the difference between TLV2620IDR and TLV2621IDR?

A: Based on the provided specifications, the TLV2620IDR and TLV2621IDR have identical electrical parameters, slew rate, gain bandwidth product, supply current, output current, and operating temperature range. Both are designated Last Time Buy status.

Q: Are all substitute parts ROHS3 compliant?

A: The MCP6293T-E/SN, TLV2620IDR, and TLV2621IDR are confirmed ROHS3 compliant. The OPA338UA compliance status is not specified in the provided data.

Q: What is the impact of the Last Time Buy designation on TLV2620IDR and TLV2621IDR?

A: Last Time Buy status indicates these parts are in the final phase of production with limited future availability. Designs should prioritize the active-status MCP6293T-E/SN for long-term supply continuity, or transition to alternative solutions for new designs.

Q: Can I use these substitutes interchangeably on the same PCB?

A: All substitute parts share the 8-SOIC package geometry and can be placed in the same footprint. However, electrical performance differences (slew rate, gain bandwidth product, input offset voltage, output current) may affect circuit behavior. Circuit validation is required when substituting between different manufacturers or part numbers.

Q: Which substitute offers the best performance for precision applications?

A: The OPA338UA provides the lowest input offset voltage (0.5 µV) and input bias current (0.2 pA), making it suitable for precision applications within the -40°C to 85°C operating range.

Q: What are the supply voltage compatibility constraints?

A: The MCP6293T-E/SN operates at 2.4 V to 6 V. All substitute parts operate at 2.7 V to 5.5 V. Applications using supply voltages below 2.7 V or above 5.5 V are incompatible with the substitute parts but compatible with the primary MCP6293T-E/SN.
