LTC6246CS6#TRPBF Equivalent & Substitute Parts

Part Overview

The LTC6246CS6#TRPBF is a general-purpose operational amplifier manufactured by Analog Devices Inc., configured as a single-circuit rail-to-rail amplifier in a TSOT-23-6 surface-mount package. This device is designated as Last Time Buy, indicating discontinued production status. The LTC6246CS6#TRPBF delivers high-speed performance with a 180 MHz gain-bandwidth product and 90 V/µs slew rate, suitable for applications requiring fast signal conditioning and amplification across a 2.5 V to 5.25 V supply range.

Due to the Last Time Buy status, equivalent substitute parts are necessary for ongoing design support and procurement continuity. Suitable alternatives must maintain functional compatibility through matching package type, pin configuration, and core electrical parameters within acceptable operating ranges.

Substitute Part Grouping Explanation

Substitute parts for the LTC6246CS6#TRPBF are selected based on the following critical parameters that determine functional interchangeability:

Package Compatibility: All substitute parts must use SOT-23-6 surface-mount packaging with identical pin configuration to ensure direct board-level replacement without layout modifications.

Electrical Specifications: Substitute parts must operate within the supply voltage range of 2.5 V to 5.25 V minimum and support rail-to-rail output operation. Single-circuit general-purpose amplifier topology is required.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and EAR99 export classification to satisfy regulatory and procurement standards equivalent to the original part.

Product Status: Active production status of substitute parts ensures long-term availability and supply chain continuity, addressing the Last Time Buy status of the original device.

The OPA341NA/250 and OPA341NA/3K from Texas Instruments meet these substitution criteria through matching package type, rail-to-rail output capability, compatible supply voltage ranges, and active product status.

Engineering Selection Recommendations

Primary Substitutes: The OPA341NA/250 and OPA341NA/3K are functionally equivalent substitutes for the LTC6246CS6#TRPBF. Both devices share identical package configuration, supply voltage compatibility, and rail-to-rail output characteristics. The distinction between OPA341NA/250 and OPA341NA/3K relates to tape reel packaging specifications (250-unit and 3000-unit reels respectively) rather than electrical performance.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and EAR99 export classification, satisfying regulatory requirements equivalent to the original device. The active product status of both OPA341 variants ensures sustained availability and manufacturing support.

Supply Voltage Consideration: Substitute parts support a maximum supply voltage of 5.5 V, which exceeds the LTC6246CS6#TRPBF specification of 5.25 V. This provides additional operational margin within standard industrial supply tolerances.

Operating Temperature Range: Substitute parts operate across -55°C to 125°C, extending beyond the original device range of 0°C to 70°C. Applications limited to the original temperature specification remain fully compatible with substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the OPA341NA/250 and OPA341NA/3K be used interchangeably with the LTC6246CS6#TRPBF?

A: Yes. Both OPA341 variants are direct substitutes. The primary difference between OPA341NA/250 and OPA341NA/3K is the tape reel quantity (250 units versus 3000 units per reel). Electrical performance and package configuration are identical.

Q: Are there any pin configuration differences between the LTC6246CS6#TRPBF and substitute parts?

A: No. All parts use SOT-23-6 packaging with identical pin assignments, enabling direct board-level replacement without schematic or layout modifications.

Q: What is the difference between the OPA341NA/250 and OPA341NA/3K part numbers?

A: The suffix designates packaging reel size. OPA341NA/250 is supplied in 250-unit tape reels, while OPA341NA/3K is supplied in 3000-unit tape reels. Electrical specifications and performance are identical.

Q: Do the substitute parts operate within the same supply voltage range?

A: The substitute parts support 2.5 V to 5.5 V operation, which encompasses the original LTC6246CS6#TRPBF range of 2.5 V to 5.25 V. The additional 0.25 V maximum rating provides operational margin.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both OPA341NA/250 and OPA341NA/3K are ROHS3 compliant, matching the compliance status of the original device.

Q: What is the product status of the substitute parts?

A: Both OPA341 variants are Active products with ongoing manufacturing support, addressing the Last Time Buy status of the LTC6246CS6#TRPBF and ensuring long-term procurement availability.
