LT1783CS5#TRMPBF Equivalent & Substitute Parts

Part Overview

The LT1783CS5#TRMPBF is a general purpose operational amplifier manufactured by Analog Devices Inc., designed for rail-to-rail applications in a compact TSOT-23-5 surface mount package. This single-circuit amplifier operates across a 2.5 V to 18 V supply range and is classified as an active product with full RoHS3 compliance. Substitute parts are identified when original inventory is unavailable, when design flexibility permits alternative specifications, or when supply chain constraints necessitate qualified alternatives that maintain functional compatibility within the application's electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the LT1783CS5#TRMPBF is determined by the following criteria:

Primary Compatibility Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: TSOT-23-5 or equivalent SOT-23-5 footprint
• Mounting Type: Surface Mount
• Voltage - Supply Span (Min): 2.5 V or lower
• Voltage - Supply Span (Max): 18 V or higher
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The TLV2381IDBVT from Texas Instruments qualifies as a substitute part. While it exhibits different performance characteristics in slew rate, gain bandwidth product, input bias current, supply current, and output current specifications, it maintains functional compatibility through identical package footprint (SOT-23-5), single-circuit general purpose amplifier topology, rail-to-rail output configuration, and overlapping supply voltage range. Both parts are surface mount devices with ROHS3 compliance and MSL-1 moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

LT1783CS5#TRMPBF Selection Criteria: Select the LT1783CS5#TRMPBF when the application requires the specified slew rate of 0.45 V/µs and gain bandwidth product of 1.3 MHz. This part is suitable for designs operating within the 0°C to 70°C temperature range and requiring higher supply current tolerance. The part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

TLV2381IDBVT Selection Criteria: The TLV2381IDBVT from Texas Instruments serves as a functional substitute when the application can accommodate lower slew rate (0.06 V/µs) and reduced gain bandwidth product (160 kHz). This substitute offers advantages in applications requiring minimal supply current consumption (7 µA versus 230 µA) and higher input bias current precision (1 pA). The TLV2381IDBVT supports an extended operating temperature range of -40°C to 125°C and maintains ROHS3 compliance with MSL-1 rating. The minimum supply voltage is 2.7 V (versus 2.5 V for the LT1783CS5#TRMPBF), and maximum supply voltage is 16 V (versus 18 V).

Both parts are active products with identical package footprints (SOT-23-5), single-circuit topology, and rail-to-rail output configuration. Selection between these parts depends on whether the application's performance requirements align with the specified electrical parameters of each device.

Frequently Asked Questions (FAQ)

Q: Can the TLV2381IDBVT directly replace the LT1783CS5#TRMPBF in all applications?

A: The TLV2381IDBVT is mechanically and functionally compatible as a substitute due to identical package footprint (SOT-23-5), single-circuit general purpose amplifier topology, and rail-to-rail output configuration. However, electrical performance differs significantly. The TLV2381IDBVT has lower slew rate (0.06 V/µs versus 0.45 V/µs) and reduced gain bandwidth product (160 kHz versus 1.3 MHz). Applications requiring the higher performance specifications of the LT1783CS5#TRMPBF cannot use the TLV2381IDBVT as a direct substitute. Conversely, applications with relaxed bandwidth and slew rate requirements can use the TLV2381IDBVT.

Q: Are there package compatibility concerns between these parts?

A: Both parts use SOT-23-5 surface mount packages. The LT1783CS5#TRMPBF uses TSOT-23-5 packaging, while the TLV2381IDBVT uses SOT-23-5 (SC-74A) packaging. These packages are mechanically and electrically compatible for PCB footprint purposes, allowing direct substitution at the board level without layout modifications.

Q: What are the supply voltage compatibility ranges?

A: The LT1783CS5#TRMPBF operates from 2.5 V to 18 V. The TLV2381IDBVT operates from 2.7 V to 16 V. Applications requiring operation below 2.7 V or above 16 V must use the LT1783CS5#TRMPBF. Applications operating within the 2.7 V to 16 V range can use either part.

Q: How do the temperature operating ranges differ?

A: The LT1783CS5#TRMPBF operates from 0°C to 70°C. The TLV2381IDBVT operates from -40°C to 125°C. Applications requiring operation below 0°C or above 70°C must use the TLV2381IDBVT. Applications within the 0°C to 70°C range can use either part.

Q: What is the significance of the supply current difference?

A: The LT1783CS5#TRMPBF draws 230 µA of supply current, while the TLV2381IDBVT draws 7 µA. For battery-powered or low-power applications, the TLV2381IDBVT provides significant power consumption advantages. For applications where supply current is not a constraint, both parts are suitable.

Q: Are both parts RoHS3 compliant?

A: Yes, both the LT1783CS5#TRMPBF and TLV2381IDBVT are ROHS3 compliant with MSL-1 (unlimited) moisture sensitivity ratings, making them suitable for applications with environmental and regulatory compliance requirements.
