LTC1050CS8#TR Equivalent & Substitute Parts

Part Overview

The LTC1050CS8#TR is an active chopper (zero-drift) amplifier manufactured by Analog Devices Inc., designed for precision analog signal conditioning applications requiring minimal input offset voltage. This single-circuit operational amplifier is classified as a Linear Amplifier and is currently in active product status. The device is housed in an 8-SOIC surface mount package with a width of 3.90mm.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative part numbers or packaging configurations. The primary reason for identifying substitutes is to ensure design flexibility, accommodate supply chain variations, and provide alternative sourcing options while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC1050CS8#TR is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier type classification (Chopper/Zero-Drift)
• Number of circuits (1 circuit)
• Slew rate (4 V/µs)
• Gain bandwidth product (2.5 MHz)
• Input bias current (10 pA)
• Input offset voltage (0.5 µV)
• Supply current (1 mA)
• Supply voltage range (4.75 V to 16 V)

Mechanical & Package Criteria:

• Package type (8-SOIC)
• Package dimensions (0.154", 3.90mm width)
• Mounting type (Surface Mount)

Compliance & Status Criteria:

• Product status (Active)
• RoHS compliance (ROHS3 Compliant)
• Moisture sensitivity level (MSL 1)

The LTC1050CS8#TRPBF is identified as a direct substitute based on identical electrical specifications, identical package configuration, and equivalent compliance certifications. The primary distinction is the packaging format (Tape & Reel with lead-free designation) and the extended operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Parameter Comparison

Engineering Selection Recommendations

LTC1050CS8#TR is suitable for applications operating within the 0°C to 70°C temperature range with standard commercial or industrial environmental conditions. This part number is available in standard packaging format and maintains full ROHS3 compliance and REACH unaffected status.

LTC1050CS8#TRPBF is the appropriate selection for applications requiring extended operating temperature coverage (-40°C to 85°C), including military, aerospace, or harsh industrial environments. The TRPBF designation indicates Tape & Reel packaging with lead-free termination, providing enhanced supply chain flexibility and higher inventory availability (29,242 units in stock versus 856 units for the standard variant). This part maintains identical electrical performance and compliance certifications while offering broader temperature operational capability.

Both parts are active products from Analog Devices Inc. and are suitable for direct substitution within their respective temperature operating ranges. Selection between the two should be based on the specific application's temperature requirements and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can LTC1050CS8#TRPBF be used as a direct replacement for LTC1050CS8#TR?

A: Yes, LTC1050CS8#TRPBF is a direct electrical substitute for LTC1050CS8#TR. All core electrical parameters are identical, including slew rate, gain bandwidth product, input bias current, input offset voltage, and supply specifications. The primary differences are the extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and packaging format (Tape & Reel with lead-free designation). Substitution is valid when the application's temperature requirements fall within the extended range or when the standard temperature range is sufficient.

Q: What is the significance of the TRPBF designation?

A: The TRPBF designation indicates the part is supplied in Tape & Reel packaging format with lead-free (PbF) termination. This packaging format is standard for high-volume automated assembly processes and provides better handling and storage characteristics. The lead-free termination ensures compliance with RoHS3 regulations and environmental standards.

Q: Are both parts RoHS compliant?

A: Yes, both LTC1050CS8#TR and LTC1050CS8#TRPBF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the difference in operating temperature ranges?

A: LTC1050CS8#TR operates from 0°C to 70°C, suitable for standard commercial and industrial applications. LTC1050CS8#TRPBF operates from -40°C to 85°C, providing extended temperature coverage for military, aerospace, and extreme environment applications. The extended range does not affect electrical performance within the overlapping temperature window (0°C to 70°C).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, both parts use identical 8-SOIC package dimensions (0.154", 3.90mm width) and surface mount configuration. They are mechanically and electrically interchangeable at the PCB level. No layout or design modifications are required for substitution.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts have MSL 1 (Unlimited), indicating unlimited shelf life under normal storage conditions without moisture baking requirements. This simplifies inventory management and reduces handling constraints during manufacturing and assembly.

Q: Which part should be selected for new designs?

A: For new designs, LTC1050CS8#TRPBF is the preferred choice due to extended temperature range capability, higher inventory availability, and standard Tape & Reel packaging format. This part provides greater design flexibility and supply chain resilience without performance trade-offs.
