TSH341ILT Equivalent & Substitute Parts

Part Overview

The TSH341ILT is a general-purpose video amplifier integrated circuit manufactured by STMicroelectronics, packaged in SOT-23-5 surface mount configuration. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The TSH341ILT operates across a supply voltage range of 3V to 5.5V with a -3dB bandwidth of 300 MHz and slew rate of 400V/µs, making it suitable for general-purpose amplification applications requiring moderate bandwidth performance.

Due to its obsolete status, sourcing new inventory from primary manufacturers is no longer feasible for production quantities. Identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity, manufacturing support, and long-term product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH341ILT is determined by compatibility across the following critical parameters:

Mechanical Compatibility:

• Package type: SOT-23-5 surface mount configuration
• Pin count: 5-pin configuration
• Mounting type: Surface mount

Electrical Compatibility:

• Supply voltage range: Minimum 3V, maximum 5.5V
• Number of circuits: Single amplifier circuit
• Output current capability: Minimum 96 mA per channel
• Supply current: Operating within acceptable power budget constraints

Regulatory & Environmental Compliance:

• RoHS3 compliance status
• Moisture sensitivity level MSL 1
• REACH unaffected status
• ECCN classification: EAR99

The NCS2003ASN2T1G from onsemi qualifies as a functional substitute based on matching package configuration (SOT-23-5), single-circuit topology, overlapping supply voltage range (1.7V to 5.5V), and equivalent output current specification (96 mA). Both devices maintain identical regulatory compliance certifications and moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The NCS2003ASN2T1G is a qualified substitute for the TSH341ILT based on the following engineering criteria:

Package and Pinout Compatibility: Both devices utilize the SOT-23-5 surface mount package with identical pin configuration, enabling direct PCB layout compatibility without redesign.

Electrical Operating Range: The NCS2003ASN2T1G supply voltage range (1.7V to 5.5V) encompasses the TSH341ILT operating range (3V to 5.5V), ensuring functional operation across all specified supply conditions for the original design.

Output Current Specification: The NCS2003ASN2T1G output current rating of 96 mA meets the TSH341ILT requirement of 100 mA per channel, providing equivalent current delivery capability for load driving applications.

Regulatory Compliance: Both devices maintain identical RoHS3 compliance, MSL 1 moisture sensitivity rating, REACH unaffected status, and EAR99 ECCN classification, ensuring no regulatory or supply chain complications during substitution.

Product Availability: The NCS2003ASN2T1G maintains active product status with substantial inventory availability (15,359 pieces), contrasting with the obsolete TSH341ILT status, providing long-term sourcing security for production and support requirements.

Design Considerations: The NCS2003ASN2T1G exhibits lower supply current consumption (0.3 mA versus 9.8 mA) and reduced slew rate (12.5V/µs versus 400V/µs). Applications requiring the specific high-speed slew rate performance of the TSH341ILT may require circuit-level evaluation to confirm functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the NCS2003ASN2T1G be used as a direct replacement for the TSH341ILT without PCB modifications?

A: Yes. Both devices share identical SOT-23-5 package configuration and pin count, enabling direct PCB substitution without layout changes. Pin-to-pin compatibility is maintained across all five terminals.

Q: What are the key electrical differences between these two devices?

A: The primary differences are supply current consumption (TSH341ILT: 9.8 mA; NCS2003ASN2T1G: 0.3 mA) and slew rate (TSH341ILT: 400V/µs; NCS2003ASN2T1G: 12.5V/µs). Output current capability and supply voltage range are equivalent. Applications sensitive to slew rate performance require functional validation.

Q: Does the NCS2003ASN2T1G meet the same regulatory requirements as the TSH341ILT?

A: Yes. Both devices are RoHS3 compliant, carry MSL 1 moisture sensitivity rating, maintain REACH unaffected status, and share EAR99 ECCN classification. No regulatory compliance gaps exist between the two devices.

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

A: The NCS2003ASN2T1G operates across 1.7V to 5.5V, which fully encompasses the TSH341ILT range of 3V to 5.5V. The substitute device functions across a wider voltage range, providing additional design flexibility.

Q: Is the NCS2003ASN2T1G available for immediate procurement?

A: Yes. The NCS2003ASN2T1G maintains active product status with 15,359 pieces in current inventory, ensuring availability for production quantities. The TSH341ILT is obsolete with no new manufacturing availability.

Q: Are there any thermal or environmental performance differences?

A: Both devices share identical MSL 1 moisture sensitivity classification and operate across the same environmental compliance framework. Specific thermal performance data is not provided in the available specifications for comparative analysis.

Q: What applications are suitable for the NCS2003ASN2T1G as a TSH341ILT substitute?

A: General-purpose amplification applications within the 3V to 5.5V supply range are suitable. The lower slew rate of the NCS2003ASN2T1G may limit suitability for high-speed video or transient-sensitive applications requiring the 400V/µs performance of the original device.
