Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2620IDBVT is determined by the following critical parameters:

Package Compatibility: All substitute parts must use SOT-23-6 surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts.

Functional Requirements: Substitute parts must provide single-channel (1 circuit) rail-to-rail output amplification with general purpose operational amplifier characteristics.

Electrical Operating Range: Substitute parts must support the minimum supply voltage of 2.7 V and maximum supply voltage of 5.5 V to maintain compatibility with the original design's power distribution architecture.

Environmental Compliance: All substitute parts must maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating to satisfy regulatory and manufacturing process requirements.

Performance Envelope: Substitute parts must operate within the -40°C to 125°C temperature range and maintain rail-to-rail output capability.

Two substitute parts meet these criteria: TLV9061SIDBVR (Texas Instruments CMOS variant) and MCP6293T-E/CH (Microchip Technology general purpose variant).

Parameter Comparison

Engineering Selection Recommendations

TLV9061SIDBVR Selection Criteria:

The TLV9061SIDBVR is a CMOS-based operational amplifier from Texas Instruments with active product status. This substitute maintains identical package configuration (SOT-23-6) and operating temperature range (-40°C to 125°C). The device supports the full 2.7 V to 5.5 V supply range required by the original design. Key electrical parameters remain within acceptable tolerance: slew rate of 6.5 V/µs (versus 7 V/µs), gain bandwidth product of 10 MHz (versus 11 MHz), and input offset voltage of 300 µV (versus 250 µV). Supply current consumption is reduced to 538 µA compared to 800 µA. Output current capability is increased to 50 mA versus 28 mA. All regulatory certifications (ROHS3, REACH unaffected, MSL 1) are maintained. This substitute is suitable for applications where lower supply current consumption is beneficial and the slightly reduced bandwidth is acceptable.

MCP6293T-E/CH Selection Criteria:

The MCP6293T-E/CH is a general purpose operational amplifier from Microchip Technology with active product status. This substitute maintains identical package configuration (SOT-23-6) and operating temperature range (-40°C to 125°C). The device supports an extended supply range of 2.4 V to 6 V, encompassing the original 2.7 V to 5.5 V requirement. Electrical performance is comparable: slew rate of 7 V/µs (identical), gain bandwidth product of 10 MHz (versus 11 MHz), and output current of 25 mA (versus 28 mA). Input bias current is reduced to 1 pA (versus 2 pA). Supply current consumption is significantly reduced to 1 µA. Input offset voltage is 3 mV (versus 250 µV), representing a notable difference in DC precision. All regulatory certifications (ROHS3, REACH unaffected, MSL 1) are maintained. This substitute is suitable for applications prioritizing ultra-low supply current consumption and where higher input offset voltage is tolerable.

Frequently Asked Questions (FAQ)

Q: Can TLV9061SIDBVR be used as a direct replacement for TLV2620IDBVT in all applications?

A: TLV9061SIDBVR is mechanically and electrically compatible within the specified parameter ranges. However, the CMOS architecture and slightly reduced gain bandwidth product (10 MHz versus 11 MHz) may affect high-frequency performance. Applications operating near the 11 MHz bandwidth limit require circuit validation.

Q: What is the primary difference between TLV9061SIDBVR and MCP6293T-E/CH?

A: TLV9061SIDBVR is a CMOS device with 538 µA supply current and 300 µV input offset voltage. MCP6293T-E/CH is a general purpose device with 1 µA supply current and 3 mV input offset voltage. Selection depends on whether low supply current or low input offset voltage is the design priority.

Q: Are all three parts (TLV2620IDBVT, TLV9061SIDBVR, MCP6293T-E/CH) pin-compatible?

A: All three parts use SOT-23-6 packaging. Pin compatibility must be verified against individual device datasheets, as SOT-23-6 packaging does not guarantee identical pin assignments across different manufacturers and product lines.

Q: What is the significance of the TLV2620IDBVT "Last Time Buy" status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory is available for final purchases, but no future production is planned. Substitution with active-status parts (TLV9061SIDBVR or MCP6293T-E/CH) is necessary for long-term design support.

Q: Does the extended supply range of MCP6293T-E/CH (2.4 V to 6 V) provide any advantage?

A: The extended minimum supply voltage of 2.4 V (versus 2.7 V for TLV2620IDBVT) allows operation in lower-voltage applications. The extended maximum of 6 V provides additional margin above the 5.5 V upper limit of the original part.

Q: How do the input offset voltage differences affect circuit design?

A: TLV2620IDBVT and TLV9061SIDBVR have input offset voltages of 250 µV and 300 µV respectively, suitable for precision applications. MCP6293T-E/CH has 3 mV offset voltage, requiring offset nulling or calibration in precision DC applications. AC-coupled or high-gain applications may be unaffected.

Q: Are there any supply current consumption implications for battery-powered designs?

A: MCP6293T-E/CH offers ultra-low supply current of 1 µA, ideal for battery-powered applications. TLV9061SIDBVR consumes 538 µA, and TLV2620IDBVT consumes 800 µA. For always-on circuits, MCP6293T-E/CH provides significant power savings.

Q: Do all substitute parts maintain the same output current capability?

A: Output current varies: TLV2620IDBVT provides 28 mA, TLV9061SIDBVR provides 50 mA (higher), and MCP6293T-E/CH provides 25 mA (slightly lower). Applications requiring maximum output current should verify compatibility with the selected substitute.
