LT6000IDCB Equivalent & Substitute Parts

Part Overview

The LT6000IDCB is a general-purpose operational amplifier manufactured by Analog Devices Inc., designed for rail-to-rail applications in a compact 6-DFN (2x3) surface mount package. This device features a single amplifier circuit with low input bias current and operates across a wide supply voltage range of 1.8 V to 18 V.

The LT6000IDCB carries an obsolete product status, making it necessary to identify equivalent and substitute components for new designs and ongoing production requirements. Substitute parts maintain functional compatibility while offering improved availability and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT6000IDCB is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Amplifier type: General Purpose
• Number of circuits: 1
• Output configuration: Rail-to-Rail
• Slew rate: 0.018 V/µs
• Gain bandwidth product: 60 kHz

Electrical Parameters:

• Input bias current: 12 nA (main part specification)
• Input offset voltage: 500 µV
• Supply current: 15 µA (main part specification)
• Output current per channel: 10 mA
• Supply voltage range: 1.8 V to 18 V

Physical Parameters:

• Package type: 6-WFDFN Exposed Pad
• Mounting: Surface Mount
• Moisture sensitivity: MSL 1 (Unlimited)

Environmental Parameters:

• Operating temperature range: -40°C to 85°C

The LT6000IDCB#TRPBF qualifies as a direct substitute based on identical functional specifications, package configuration, and environmental ratings. Differences in input bias current (4 nA vs. 12 nA) and supply current (20 µA vs. 15 µA) represent improvements in the substitute part and do not preclude substitution in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

The LT6000IDCB#TRPBF is the direct substitute for the obsolete LT6000IDCB. Selection of the substitute part is based on the following engineering criteria:

Product Status: The LT6000IDCB carries obsolete status, while the LT6000IDCB#TRPBF maintains active product status with ongoing manufacturer support and guaranteed availability.

Regulatory Compliance: The LT6000IDCB#TRPBF is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in industrial and commercial applications.

Functional Equivalence: Both parts maintain identical electrical specifications for amplifier type, output configuration, slew rate, gain bandwidth product, input offset voltage, and output current capability. The substitute part demonstrates improved input bias current (4 nA vs. 12 nA) and maintains compatibility with the original 1.8 V to 18 V supply range, with the substitute rated to 16 V maximum.

Package Compatibility: Both parts utilize the 6-WFDFN Exposed Pad surface mount package with identical pinout and thermal characteristics, enabling direct board-level substitution without layout modifications.

Packaging Format: The LT6000IDCB#TRPBF is supplied in Cut Tape (CT) and Digi-Reel® packaging, providing standard production-ready formats for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the LT6000IDCB#TRPBF be used as a direct replacement for the LT6000IDCB in existing designs?

A: Yes. The LT6000IDCB#TRPBF is a direct substitute with identical package, pinout, and functional specifications. The substitute part meets or exceeds the electrical performance of the original part across all critical parameters.

Q: What is the difference in input bias current between the two parts?

A: The LT6000IDCB specifies 12 nA input bias current, while the LT6000IDCB#TRPBF specifies 4 nA. This represents an improvement in the substitute part and does not affect substitution compatibility. Applications designed for 12 nA will operate within specification with the lower 4 nA bias current.

Q: Are there differences in supply voltage ratings?

A: The LT6000IDCB is rated for 1.8 V to 18 V supply operation. The LT6000IDCB#TRPBF is rated for 1.8 V to 16 V. For applications operating above 16 V, the original part specification must be retained. For applications within the 1.8 V to 16 V range, the substitute part is fully compatible.

Q: What packaging formats are available for the substitute part?

A: The LT6000IDCB#TRPBF is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, both suitable for automated pick-and-place assembly and standard production workflows.

Q: Does the substitute part meet current environmental regulations?

A: Yes. The LT6000IDCB#TRPBF is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Is the 6-WFDFN Exposed Pad package identical between both parts?

A: Yes. Both the LT6000IDCB and LT6000IDCB#TRPBF use the 6-WFDFN Exposed Pad package with identical pinout, dimensions, and thermal characteristics, enabling direct board-level substitution.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
