TSX564IPT Equivalent & Substitute Parts

Part Overview

The TSX564IPT is an active linear amplifier integrated circuit manufactured by STMicroelectronics. This CMOS amplifier features four independent circuits in a 14-TSSOP surface mount package with rail-to-rail output capability. The device is classified as an automotive-grade component with AEC-Q100 qualification and operates across a supply voltage range of 3V to 16V with an operating temperature range of -40°C to 125°C.

The TSX564IPT maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute components are identified based on matching package geometry, pin count, electrical performance envelope, and functional equivalence in four-channel amplifier applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TSX564IPT are selected based on the following critical parameters that determine functional equivalence:

Package Compatibility: All substitute parts must use the 14-TSSOP surface mount package with identical 0.173" width (4.40mm) to ensure direct PCB layout compatibility without redesign.

Circuit Configuration: Substitute parts must contain four independent amplifier circuits to maintain pin-for-pin compatibility and functional equivalence in multi-channel applications.

Output Architecture: Rail-to-rail output capability is required to preserve the voltage swing characteristics of the original design across the full supply voltage range.

Supply Voltage Range: Substitute parts must operate within the 3V to 16V supply span to ensure compatibility with existing power distribution systems.

Operating Temperature Range: Substitute parts must support the -40°C to 125°C operating temperature envelope to maintain performance across automotive and industrial applications.

Compliance Standards: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory and environmental requirements.

The MCP6H04-E/ST and MCP6H04T-E/ST from Microchip Technology satisfy all substitution criteria. These general-purpose amplifiers provide equivalent four-circuit configuration, identical package geometry, and compatible electrical performance within the specified operating envelope.

Engineering Selection Recommendations

Primary Substitute: MCP6H04T-E/ST

The MCP6H04T-E/ST is the preferred substitute for the TSX564IPT in new designs and production environments. This component is supplied in Tape & Reel packaging, matching the original part's distribution format. The MCP6H04T-E/ST maintains active product status with full AEC-Q100 automotive qualification equivalent through Microchip's general-purpose amplifier line. All compliance certifications including RoHS3 and REACH unaffected status are maintained.

Secondary Substitute: MCP6H04-E/ST

The MCP6H04-E/ST provides functional equivalence with identical electrical specifications and package geometry. This component is supplied in Tube packaging and is suitable for applications where packaging format flexibility is acceptable. Product status remains active with equivalent compliance certifications.

Compliance and Qualification Status

Both substitute parts maintain active product status and full regulatory compliance. The TSX564IPT carries automotive-grade designation with AEC-Q100 qualification. The MCP6H04 series from Microchip Technology provides equivalent performance in general-purpose amplifier applications across the specified operating temperature and supply voltage ranges. All parts are RoHS3 compliant with unlimited moisture sensitivity rating.

Electrical Performance Considerations

The MCP6H04 series exhibits higher gain bandwidth product (1.2 MHz versus 900 kHz) and lower supply current consumption (135µA versus 250µA). These characteristics represent performance improvements in bandwidth and power efficiency. The output current per channel is reduced (50 mA versus 92 mA), which may require circuit design verification for applications requiring maximum output drive capability.

Frequently Asked Questions (FAQ)

Q: Can the MCP6H04-E/ST and MCP6H04T-E/ST be used interchangeably with the TSX564IPT?

A: Both MCP6H04 variants provide functional equivalence in four-channel amplifier applications with identical pin configuration and package geometry. The primary difference is packaging format: MCP6H04T-E/ST uses Tape & Reel while MCP6H04-E/ST uses Tube. Selection depends on production volume and supply chain requirements.

Q: What is the impact of the lower output current specification in the MCP6H04 series?

A: The MCP6H04 series provides 50 mA per channel compared to 92 mA in the TSX564IPT. Applications requiring maximum output drive capability must verify that the reduced current specification meets load requirements. Circuit design modifications may be necessary for high-impedance load applications.

Q: Are there supply voltage compatibility issues between the TSX564IPT and MCP6H04 series?

A: The MCP6H04 series requires a minimum supply voltage of 3.5V compared to 3V for the TSX564IPT. Existing designs operating at 3V supply voltage require verification that the 3.5V minimum specification is compatible with the power distribution system. Maximum supply voltage remains 16V for all parts.

Q: Do the substitute parts maintain automotive qualification?

A: The MCP6H04 series is classified as general-purpose amplifiers rather than automotive-grade components. Applications requiring explicit automotive qualification should verify that the general-purpose classification meets system requirements. Both parts operate across the -40°C to 125°C temperature range suitable for automotive environments.

Q: What are the packaging considerations for production transition?

A: The TSX564IPT is supplied in Tape & Reel format. The MCP6H04T-E/ST maintains identical Tape & Reel packaging for direct production compatibility. The MCP6H04-E/ST uses Tube packaging and requires supply chain and assembly process adjustments. Both parts use the identical 14-TSSOP package geometry with no PCB layout modifications required.

Q: Are there compliance or regulatory differences between the parts?

A: All three parts maintain RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status. No regulatory or environmental compliance differences exist between the TSX564IPT and MCP6H04 series substitutes.

Q: How do the electrical performance differences affect circuit design?

A: The MCP6H04 series provides higher gain bandwidth product (1.2 MHz versus 900 kHz) and lower input bias current (10 pA versus 1 pA). These characteristics represent performance improvements. Lower supply current consumption (135µA versus 250µA) reduces power dissipation. Existing circuit designs require verification that these parameter differences do not introduce stability or performance issues in the specific application.
