TSH310ILT Equivalent & Substitute Parts

Part Overview

The TSH310ILT is a current feedback amplifier manufactured by STMicroelectronics, housed in a SOT-23-5 surface mount package. This device is classified as obsolete, indicating discontinuation from active production. The TSH310ILT delivers high-speed amplification with a slew rate of 115V/µs and -3dB bandwidth of 230 MHz, making it suitable for applications requiring fast transient response and wide bandwidth performance. Due to its obsolete status, identifying functionally compatible alternatives is necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH310ILT requires evaluation based on the following critical parameters:

Package Compatibility: Both the main part and substitute must share identical physical packaging (SOT-23-5 / SC-74A, SOT-753) to ensure direct board-level compatibility without layout modifications.

Electrical Interface: Single-circuit operational amplifier topology with surface mount configuration and identical supply voltage range compatibility (4.5V to 5.5V minimum overlap).

Environmental & Compliance Alignment: Operating temperature range (-40°C to 85°C), RoHS3 compliance, MSL Level 1, and REACH unaffected status must be maintained across substitutes.

Performance Characteristics: While the TSH310ILT is a current feedback amplifier optimized for high-speed applications, substitute parts may operate under different amplifier topologies (general purpose, rail-to-rail) provided they meet the physical and electrical interface requirements for the application circuit.

The MCP6001T-I/OT is identified as a substitute based on matching package type, surface mount configuration, single-circuit design, identical operating temperature range, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

TSH310ILT Status: The TSH310ILT is obsolete and no longer manufactured by STMicroelectronics. This status necessitates identification of alternative components for new designs or production continuity.

MCP6001T-I/OT Suitability: The MCP6001T-I/OT is an active product from Microchip Technology with confirmed availability (557,200 units in stock). It shares identical physical packaging (SOT-23-5), surface mount configuration, single-circuit topology, and operating temperature range with the TSH310ILT. Both devices maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status.

Performance Trade-offs: The MCP6001T-I/OT operates as a general purpose, rail-to-rail amplifier with significantly lower slew rate (0.6V/µs versus 115V/µs) and reduced bandwidth (1 MHz gain bandwidth product versus 230 MHz). The substitute exhibits lower input bias current (1 pA versus 3.1 µA), higher input offset voltage (4.5 mV versus 1.7 mV), and reduced output current capability (23 mA versus 110 mA). The MCP6001T-I/OT supports a wider minimum supply voltage range (1.8V versus 4.5V).

Selection Basis: Component selection between the TSH310ILT and MCP6001T-I/OT must be determined by application-specific performance requirements. The TSH310ILT's high-speed characteristics (115V/µs slew rate, 230 MHz bandwidth) are suitable for transient-rich, wideband signal processing. The MCP6001T-I/OT is appropriate for low-frequency, general-purpose amplification with lower power consumption and extended supply voltage flexibility. Both devices meet identical compliance and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the MCP6001T-I/OT directly replace the TSH310ILT in existing designs?

A: Physical package compatibility (SOT-23-5) permits direct board-level substitution without layout modification. However, electrical performance differences require circuit-level evaluation. The MCP6001T-I/OT's significantly lower slew rate (0.6V/µs) and bandwidth (1 MHz) differ substantially from the TSH310ILT's high-speed characteristics (115V/µs, 230 MHz). Applications dependent on fast transient response or wideband performance may not function correctly with the MCP6001T-I/OT.

Q: What are the key performance differences between these devices?

A: The TSH310ILT is a current feedback amplifier optimized for high-speed applications with 115V/µs slew rate and 230 MHz bandwidth. The MCP6001T-I/OT is a general purpose, rail-to-rail amplifier with 0.6V/µs slew rate and 1 MHz gain bandwidth product. The TSH310ILT provides higher output current (110 mA) and lower input offset voltage (1.7 mV). The MCP6001T-I/OT offers lower input bias current (1 pA) and lower supply current (100 µA).

Q: Are both devices available in the same packaging?

A: Yes. Both the TSH310ILT and MCP6001T-I/OT are housed in SC-74A, SOT-753 packages (SOT-23-5 supplier designation) with surface mount configuration. This identical packaging permits direct board-level substitution without PCB redesign.

Q: What is the supply voltage compatibility between these parts?

A: The TSH310ILT operates within 4.5V to 5.5V supply range. The MCP6001T-I/OT operates within 1.8V to 6V supply range. The overlap region (4.5V to 5.5V) permits substitution in circuits designed for the TSH310ILT's supply specification. Circuits utilizing the MCP6001T-I/OT's extended lower voltage capability (1.8V to 4.5V) cannot use the TSH310ILT.

Q: Do both devices meet the same compliance standards?

A: Yes. Both the TSH310ILT and MCP6001T-I/OT are ROHS3 compliant, carry MSL Level 1 (unlimited moisture sensitivity), and are REACH unaffected. Both devices operate across the identical temperature range (-40°C to 85°C).

Q: Why is the TSH310ILT marked as obsolete?

A: The TSH310ILT is classified as obsolete, indicating discontinuation from active production by STMicroelectronics. Obsolete status reflects end-of-life designation and unavailability for new orders from the manufacturer. The MCP6001T-I/OT maintains active product status with confirmed ongoing production and availability.

Q: What applications are suitable for each device?

A: The TSH310ILT's high slew rate (115V/µs) and wide bandwidth (230 MHz) suit high-speed signal conditioning, transimpedance amplification, and wideband filtering applications. The MCP6001T-I/OT's lower bandwidth (1 MHz) and reduced slew rate suit low-frequency sensor signal conditioning, audio amplification, and general-purpose analog signal processing where high-speed performance is not required.
