Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT1028CS8#TR is determined by the following criteria:

Direct Substitutes (Identical Electrical and Mechanical Specifications): Direct substitutes maintain all electrical parameters within specification limits and share the identical 8-SOIC package form factor. These parts are interchangeable without circuit redesign.

Similar Substitutes (Compatible Electrical Performance with Functional Differences): Similar substitutes operate within the same package envelope and supply voltage range but may exhibit different amplifier classifications, bandwidth characteristics, or bias current specifications. Selection requires verification that the application tolerates these parameter variations.

Critical Substitution Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Voltage - Supply Span: 8 V minimum to 36 V maximum
• Mounting Type: Surface Mount
• Number of Circuits: 1
• RoHS3 Compliance and REACH Unaffected status

Parameter Comparison

Engineering Selection Recommendations

LT1028CS8#TRPBF (Direct Substitute): The LT1028CS8#TRPBF is a direct electrical and mechanical equivalent to the LT1028CS8#TR. Both parts share identical electrical specifications, package form factor, and compliance certifications. The primary distinction is packaging format: LT1028CS8#TRPBF is supplied in Tape & Reel configuration with significantly higher inventory availability (88,988 units). Selection of this substitute is appropriate for production volumes requiring reel packaging or when the original part number is unavailable.

INA141U (Similar Substitute): The INA141U is a Texas Instruments instrumentation amplifier that shares the 8-SOIC package envelope and operates within the 8 V to 36 V supply range. This part exhibits lower slew rate (4 V/µs versus 15 V/µs), reduced input bias current (2 nA versus 30 nA), and lower supply current (0.75 mA versus 7.6 mA). The INA141U supports extended operating temperature range (-40°C to 85°C) and features higher moisture sensitivity classification (MSL 3). Selection of this substitute is appropriate only when the application requirements accommodate the reduced bandwidth and slew rate characteristics, and when the extended temperature range provides system benefit.

All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can LT1028CS8#TRPBF be used as a direct replacement for LT1028CS8#TR?

A: Yes. The LT1028CS8#TRPBF is electrically and mechanically identical to the LT1028CS8#TR. Both parts feature identical slew rate (15 V/µs), gain bandwidth product (75 MHz), input bias current (30 nA), input offset voltage (20 µV), and supply current (7.6 mA). The parts are interchangeable without circuit modification. The primary difference is packaging format: LT1028CS8#TRPBF is supplied in Tape & Reel configuration.

Q: Is the INA141U compatible with LT1028CS8#TR applications?

A: The INA141U shares the 8-SOIC package form factor and operates within the same supply voltage range (8 V to 36 V maximum). However, the INA141U exhibits significantly different electrical characteristics: slew rate of 4 V/µs (versus 15 V/µs), -3dB bandwidth of 1 MHz (versus 75 MHz gain bandwidth product), and input bias current of 2 nA (versus 30 nA). The INA141U is classified as an instrumentation amplifier rather than a general purpose amplifier. Substitution is appropriate only when the application tolerates reduced bandwidth and slew rate performance.

Q: What is the difference between the packaging formats of LT1028CS8#TR and LT1028CS8#TRPBF?

A: LT1028CS8#TR is supplied in standard packaging format, while LT1028CS8#TRPBF is supplied in Tape & Reel (TR) configuration. Both parts are identical electrically and mechanically. Tape & Reel packaging is standard for high-volume production assembly. The selection between these formats depends on manufacturing process requirements and inventory management practices.

Q: What are the moisture sensitivity implications of selecting INA141U?

A: The LT1028CS8#TR and LT1028CS8#TRPBF are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The INA141U is classified as MSL 3 (168 Hours), requiring controlled storage conditions and limiting shelf life after packaging is opened. If the application environment or manufacturing process involves extended exposure to moisture, the MSL 3 classification of INA141U may introduce additional handling and storage requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The LT1028CS8#TR, LT1028CS8#TRPBF, and INA141U are all RoHS3 compliant and REACH unaffected. All parts meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the operating temperature range difference between the main part and INA141U?

A: The LT1028CS8#TR operates from 0°C to 70°C. The INA141U operates from -40°C to 85°C, providing extended temperature range capability. Selection of INA141U is appropriate when the application requires operation at temperatures below 0°C or above 70°C.
