TSH63CDT Equivalent & Substitute Parts

Part Overview

The TSH63CDT is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring three independent circuits in a 14-SOIC surface-mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The TSH63CDT delivers rail-to-rail output capability with a 60 MHz gain-bandwidth product and 98 V/µs slew rate, suitable for general-purpose signal conditioning and amplification applications.

Due to its obsolete status, identifying functionally equivalent active alternatives is essential for design continuity, procurement reliability, and long-term system support. Substitute parts must maintain compatibility across electrical performance, package form factor, and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH63CDT is determined by strict alignment across the following critical parameters:

Mechanical Compatibility: Package form factor must be 14-SOIC with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout redesign.

Electrical Compatibility: The substitute must support the same number of circuits (3 independent amplifiers), maintain rail-to-rail output capability, and operate within the supply voltage range of 5 V to 12 V minimum and maximum specifications.

Performance Envelope: Substitute devices must meet or exceed the slew rate (98 V/µs), gain-bandwidth product (60 MHz), and output current per channel (45 mA) to ensure functional equivalence in signal conditioning applications.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and surface-mount technology to align with manufacturing and environmental standards.

The MAX4019ESD+ and MAX4019ESD+T devices satisfy these substitution criteria. Both are active, three-circuit rail-to-rail amplifiers in 14-SOIC packages with enhanced electrical performance characteristics and extended operating temperature ranges.

Engineering Selection Recommendations

For Active Production and New Designs: The MAX4019ESD+T is the primary substitute for the TSH63CDT. This device is manufactured by Analog Devices Inc./Maxim Integrated with active product status, ensuring long-term availability and manufacturing support. The MAX4019ESD+T is supplied in Tape & Reel packaging, matching the original TSH63CDT format and optimizing for high-volume production environments. ROHS3 compliance is maintained, and the extended operating temperature range (-40°C to 85°C) provides broader environmental flexibility compared to the TSH63CDT specification (0°C to 70°C).

For Existing Inventory or Alternative Sourcing: The MAX4019ESD+ serves as a secondary substitute with identical electrical specifications to the MAX4019ESD+T. This variant is supplied in Tube packaging rather than Tape & Reel, making it suitable for lower-volume applications or situations where reel format is not required. Both MAX4019 variants deliver superior electrical performance, including 600 V/µs slew rate and 140 MHz gain-bandwidth product, exceeding the TSH63CDT baseline specifications.

Supply Voltage Consideration: The MAX4019 series operates at a minimum supply voltage of 3.15 V, which is lower than the TSH63CDT minimum of 5 V. In applications requiring strict 5 V to 12 V operation, the MAX4019 devices remain fully compatible and functional across this range. The maximum supply voltage for MAX4019 is 11 V, which is within the TSH63CDT maximum of 12 V, requiring verification in designs operating at the upper supply limit.

Regulatory and Compliance Status: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, aligning with the TSH63CDT environmental certifications. No additional compliance modifications are required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the MAX4019ESD+T directly replace the TSH63CDT without PCB modifications?

A: Yes. Both devices use identical 14-SOIC packages with 0.154" (3.90mm) width, ensuring footprint compatibility. No PCB layout changes are required for mechanical substitution.

Q: What are the key electrical differences between the TSH63CDT and MAX4019ESD+T?

A: The MAX4019ESD+T provides enhanced performance across multiple parameters: slew rate increases from 98 V/µs to 600 V/µs, gain-bandwidth product increases from 60 MHz to 140 MHz, and output current per channel increases from 45 mA to 120 mA. Input bias current is slightly lower (5.4 µA versus 6 µA), while input offset voltage is higher (4 mV versus 1.5 mV). These differences indicate improved high-frequency performance and output drive capability in the substitute device.

Q: Is the MAX4019ESD+ (Tube packaging) equivalent to the MAX4019ESD+T (Tape & Reel packaging)?

A: Electrically and functionally, both devices are identical. The difference is packaging format only. MAX4019ESD+T is supplied in Tape & Reel format suitable for automated assembly lines, while MAX4019ESD+ is supplied in Tube format. Select based on your production volume and assembly equipment requirements.

Q: What is the supply voltage compatibility range for substitution?

A: The TSH63CDT operates from 5 V to 12 V. The MAX4019 series operates from 3.15 V to 11 V. Direct substitution is valid across the overlapping range of 5 V to 11 V. If your design operates at exactly 12 V, verify that the 11 V maximum specification of the MAX4019 is acceptable for your application margin requirements.

Q: Does the extended operating temperature range of the MAX4019 (-40°C to 85°C) affect substitution suitability?

A: No. The extended temperature range of the MAX4019 is a superset of the TSH63CDT range (0°C to 70°C). Applications operating within the original 0°C to 70°C specification will function identically. The broader range provides additional flexibility for future applications without requiring component changes.

Q: Are there any compliance or regulatory concerns with substituting the TSH63CDT with MAX4019 devices?

A: No. Both the TSH63CDT and MAX4019 series maintain ROHS3 compliance and REACH unaffected status. No additional regulatory documentation or modifications are required for direct substitution in compliant designs.

Q: Why is the TSH63CDT classified as obsolete?

A: Obsolete status indicates that STMicroelectronics has discontinued production of this device. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. Substitution with active devices such as the MAX4019 series ensures design continuity and procurement reliability for current and future production.

Q: Can I use the MAX4019 in applications originally designed for the TSH63CDT without circuit redesign?

A: Yes, for most general-purpose amplification applications. The superior electrical performance of the MAX4019 (higher slew rate, bandwidth, and output current) makes it functionally compatible with TSH63CDT designs. However, applications with tight input offset voltage specifications (requiring the TSH63CDT's 1.5 mV specification) should evaluate the MAX4019's 4 mV offset voltage to confirm acceptable performance margins.
