TSH63CD Equivalent & Substitute Parts

Part Overview

The TSH63CD 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 TSH63CD provides rail-to-rail output capability with moderate bandwidth performance suitable for general analog signal processing applications.

Due to its obsolete status, identifying functionally compatible substitute components is necessary for ongoing system support, design updates, and procurement continuity. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, output type, circuit count, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TSH63CD are selected based on the following critical compatibility parameters:

Mandatory Matching Criteria:

• Number of Circuits: 3 independent amplifier circuits
• Output Type: Rail-to-Rail output capability
• Package Form Factor: 14-SOIC surface-mount package with 0.154" (3.90mm) width
• Supply Voltage Overlap: Minimum 5 V to maximum 12 V operating range

Acceptable Parameter Variations:

• Amplifier Type: Buffer or Voltage Feedback amplifiers are functionally compatible with general-purpose applications
• Slew Rate: Higher values indicate improved performance and are acceptable
• Gain Bandwidth Product: Higher values indicate improved performance and are acceptable
• Current - Input Bias: Lower values indicate improved performance and are acceptable
• Voltage - Input Offset: Variations within application tolerance are acceptable
• Current - Output / Channel: Higher values provide greater drive capability and are acceptable
• Operating Temperature: Extended ranges are acceptable for applications within the TSH63CD range
• Moisture Sensitivity Level: Lower MSL ratings indicate improved handling characteristics and are acceptable

The substitute parts MAX4019ESD+ and MAX4019ESD+T meet all mandatory matching criteria and provide enhanced electrical performance across multiple parameters.

Engineering Selection Recommendations

MAX4019ESD+ (Tube Packaging)

The MAX4019ESD+ is an active, production-status substitute available in tube packaging. This device maintains full electrical compatibility with the TSH63CD across all mandatory parameters: three circuits, rail-to-rail output, and 14-SOIC package form factor. The MAX4019ESD+ demonstrates superior performance characteristics including higher slew rate (600 V/µs versus 98 V/µs), increased gain bandwidth product (140 MHz versus 60 MHz), and greater output current capability (120 mA versus 45 mA per channel). Supply voltage compatibility exists within the overlapping range of 5 V to 11 V. The device carries ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. Moisture sensitivity is improved to MSL 1 (unlimited), reducing handling constraints during assembly and storage.

MAX4019ESD+T (Tape & Reel Packaging)

The MAX4019ESD+T is functionally identical to the MAX4019ESD+ with identical electrical specifications and active production status. The primary distinction is packaging format: tape and reel configuration for automated assembly processes. This variant is appropriate for high-volume manufacturing environments requiring continuous component feed. All electrical compatibility, performance enhancements, and regulatory compliance characteristics are identical to the tube-packaged variant.

Selection Basis

Both MAX4019 variants are suitable direct substitutes for the TSH63CD. Selection between tube (MAX4019ESD+) and tape & reel (MAX4019ESD+T) packaging depends on assembly process requirements. The active production status of both variants ensures long-term availability and supply chain stability, addressing the obsolescence limitation of the original TSH63CD.

Frequently Asked Questions (FAQ)

Q: Can the MAX4019ESD+ directly replace the TSH63CD in existing designs?

A: Yes. Both devices share identical package geometry (14-SOIC, 0.154" width), three-circuit configuration, and rail-to-rail output type. Pin-to-pin compatibility is maintained. The MAX4019ESD+ operates within the TSH63CD supply voltage range (5 V to 11 V overlap) and provides superior electrical performance across bandwidth, slew rate, and output current parameters.

Q: What is the difference between MAX4019ESD+ and MAX4019ESD+T?

A: The electrical specifications are identical. The difference is packaging format: MAX4019ESD+ is supplied in tube packaging for manual or semi-automated assembly, while MAX4019ESD+T is supplied in tape and reel format for fully automated pick-and-place assembly. Select based on your manufacturing process requirements.

Q: Does the TSH63CD operate at supply voltages below 5 V?

A: No. The TSH63CD minimum supply voltage is 5 V. The MAX4019 variants support lower minimum supply voltage (3.15 V), providing additional design flexibility for low-voltage applications.

Q: Are there any temperature range limitations when substituting?

A: The TSH63CD operates from 0°C to 70°C. The MAX4019 variants operate from -40°C to 85°C, providing an extended temperature range. Applications operating within the original 0°C to 70°C range are fully compatible. Applications requiring extended temperature operation benefit from the wider range of the substitute parts.

Q: What is the significance of the MSL rating difference?

A: The TSH63CD has MSL 3 (168-hour moisture sensitivity), requiring controlled storage and handling. The MAX4019 variants have MSL 1 (unlimited), eliminating moisture sensitivity constraints. This reduces handling complexity and storage requirements during manufacturing and assembly.

Q: Are regulatory certifications maintained with the substitute parts?

A: Yes. Both the TSH63CD and MAX4019 variants carry ROHS3 compliance and REACH unaffected status. ECCN classification is identical (EAR99) for both original and substitute parts.

Q: What performance improvements does the MAX4019 provide?

A: The MAX4019 offers higher slew rate (600 V/µs versus 98 V/µs), higher gain bandwidth product (140 MHz versus 60 MHz), higher -3dB bandwidth (200 MHz versus 74 MHz), and greater output current per channel (120 mA versus 45 mA). These improvements enable faster signal processing and higher load-driving capability.

Q: Is the MAX4019 suitable for general-purpose amplifier applications?

A: Yes. Although the MAX4019 is classified as a buffer/voltage feedback amplifier, it is functionally compatible with general-purpose amplifier applications. The three-circuit configuration, rail-to-rail output, and electrical characteristics support standard analog signal conditioning, buffering, and amplification functions.
