MCP6H84-E/ST Equivalent & Substitute Parts

Part Overview

The MCP6H84-E/ST is a general-purpose operational amplifier featuring four independent circuits in a 14-TSSOP surface mount package. Manufactured by Microchip Technology, this rail-to-rail output amplifier operates across a 3.5V to 12V supply range with a slew rate of 5V/µs and gain bandwidth product of 5.5 MHz. The device is classified as obsolete, necessitating identification of active substitute components for new designs and ongoing production requirements. Substitute parts must maintain functional equivalence through matching package geometry, circuit count, output characteristics, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP6H84-E/ST is based on the following critical parameters that define functional equivalence:

Package Compatibility: Both substitute parts utilize the identical 14-TSSOP package with 0.173" width and 4.40mm dimensions, ensuring direct PCB footprint compatibility without layout modifications.

Circuit Configuration: All substitute candidates maintain four independent operational amplifier circuits, preserving the quad-channel architecture required for equivalent system integration.

Output Characteristics: Rail-to-rail output capability is maintained across all substitute options, supporting the full supply voltage swing required in the original design.

Operating Temperature Range: The -40°C to 125°C operating range is preserved in substitute parts, ensuring thermal performance equivalence across industrial and extended temperature applications.

Supply Voltage Compatibility: Substitute parts operate within the 2.7V to 12V range, which encompasses the original 3.5V to 12V specification, providing backward compatibility with existing power supply designs.

Compliance Standards: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the environmental and regulatory requirements of the original component.

The TS924AIPT and TS924AIYPT variants are manufactured by STMicroelectronics and carry active product status with AEC-Q100 automotive qualification, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

Primary Substitute Selection: The TS924AIYPT is the preferred substitute for the MCP6H84-E/ST. This variant is supplied in Tape & Reel (TR) packaging with 15,300 units in current inventory, providing optimal supply chain continuity for production environments. The TS924AIYPT maintains active product status with AEC-Q100 automotive qualification, ensuring long-term availability and compliance with automotive-grade reliability standards.

Secondary Substitute Selection: The TS924AIPT serves as an alternative substitute, supplied in Cut Tape (CT) and Digi-Reel® packaging with 9,702 units in inventory. This variant is suitable for lower-volume applications or prototype development where tape and reel packaging is not required. Both TS924 variants are functionally equivalent and interchangeable at the circuit level.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the environmental requirements of the original MCP6H84-E/ST. The automotive-grade qualification of the TS924 series provides additional reliability assurance for mission-critical applications.

Supply Chain Stability: The transition from the obsolete MCP6H84-E/ST to active TS924 variants eliminates long-term availability risk. Both substitute parts are manufactured by STMicroelectronics, a tier-one semiconductor supplier with established distribution networks and production capacity.

Frequently Asked Questions (FAQ)

Q: Can the TS924AIPT and TS924AIYPT be used interchangeably with the MCP6H84-E/ST?

A: Yes. Both TS924 variants are functionally equivalent substitutes. The primary difference is packaging format: TS924AIYPT is supplied in Tape & Reel (TR) for high-volume production, while TS924AIPT is supplied in Cut Tape (CT) and Digi-Reel® for lower volumes. Circuit performance and PCB footprint are identical.

Q: What is the difference between TS924AIPT and TS924AIYPT?

A: Both parts are identical in electrical performance and package geometry (14-TSSOP). The distinction is packaging and delivery format. TS924AIYPT uses Tape & Reel packaging suitable for automated assembly lines, while TS924AIPT uses Cut Tape and Digi-Reel® packaging for manual or lower-volume assembly processes.

Q: Are there any performance differences between the MCP6H84-E/ST and the TS924 substitutes?

A: The TS924 variants have lower slew rate (1.3V/µs versus 5V/µs) and lower gain bandwidth product (4 MHz versus 5.5 MHz). However, both parameters remain within acceptable ranges for general-purpose amplifier applications. The TS924 offers superior output current capability (80 mA versus 55 mA per channel) and lower input bias current (15 nA versus 10 pA), providing improved performance in many circuit topologies.

Q: Will the TS924 substitutes work with the existing PCB layout designed for the MCP6H84-E/ST?

A: Yes. Both the MCP6H84-E/ST and TS924 variants use the identical 14-TSSOP package with 0.173" width and 4.40mm dimensions. No PCB layout modifications are required for direct component substitution.

Q: What is the minimum supply voltage for the TS924 substitutes?

A: The TS924 variants operate at a minimum supply voltage of 2.7V, compared to 3.5V for the MCP6H84-E/ST. This provides additional flexibility in low-voltage applications while maintaining full compatibility with designs using the original 3.5V to 12V supply range.

Q: Are the TS924 substitutes suitable for automotive applications?

A: Yes. Both TS924AIPT and TS924AIYPT carry AEC-Q100 automotive qualification, making them suitable for automotive-grade applications. The MCP6H84-E/ST does not carry automotive qualification.

Q: What is the operating temperature range for the substitute parts?

A: Both TS924 variants operate across the -40°C to 125°C temperature range, matching the original MCP6H84-E/ST specification and supporting industrial and extended temperature applications.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: All parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The TS924 variants add AEC-Q100 automotive qualification, providing additional reliability assurance without introducing any compliance restrictions.
