Substitute Part Grouping Explanation

Substitution eligibility for the MCP6H74-E/ST is determined by the following critical parameters:

Package Compatibility: The substitute part must use the 14-TSSOP surface-mount package with identical pin configuration and physical dimensions (0.173", 4.40mm Width).

Functional Configuration: The substitute must provide four independent general-purpose operational amplifier circuits with rail-to-rail output capability.

Electrical Operating Range: The substitute must support the supply voltage range of 3.5 V minimum to 12 V maximum and operate across the temperature range of -40°C to 125°C.

Output Characteristics: The substitute must deliver rail-to-rail output performance suitable for the same application classes.

The TS924IYPT from STMicroelectronics meets these substitution criteria. Both devices share identical package form factors, quad-channel configurations, and overlapping supply voltage specifications. The TS924IYPT operates within the required temperature range and maintains rail-to-rail output capability.

Engineering Selection Recommendations

Primary Selection (MCP6H74-E/ST): This part is recommended for applications requiring the specified slew rate of 2 V/µs and gain bandwidth product of 2.7 MHz. The device is in active production with substantial inventory availability (3,137 units). Both the MCP6H74-E/ST and TS924IYPT are ROHS3 compliant and carry MSL Level 1 ratings, indicating equivalent environmental compliance.

Substitute Selection (TS924IYPT): The TS924IYPT is suitable as a substitute when the lower minimum supply voltage of 2.7 V is advantageous for battery-powered or low-voltage applications. This device carries AEC-Q100 automotive qualification, indicating suitability for automotive-grade applications. The TS924IYPT provides higher output current capability (80 mA per channel versus 53 mA) and greater gain bandwidth product (4 MHz versus 2.7 MHz), which may benefit applications requiring faster signal processing. Current inventory is 2,800 units.

Compliance Equivalence: Both devices maintain identical RoHS3 compliance status, REACH unaffected status, and MSL Level 1 moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.33.0001.

Frequently Asked Questions (FAQ)

Q: Can the TS924IYPT directly replace the MCP6H74-E/ST in existing designs?

A: Direct replacement is possible from a package and pin-count perspective, as both devices use the 14-TSSOP surface-mount package. However, circuit performance will differ due to variations in slew rate (1.3 V/µs versus 2 V/µs), gain bandwidth product (4 MHz versus 2.7 MHz), and supply current characteristics. Design validation is necessary to confirm functional equivalence for the specific application.

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

A: The MCP6H74-E/ST operates with a minimum supply voltage of 3.5 V, while the TS924IYPT operates at 2.7 V minimum. The TS924IYPT provides higher output current per channel (80 mA versus 53 mA) and greater bandwidth (4 MHz versus 2.7 MHz). The MCP6H74-E/ST has lower input bias current (10 pA versus 15 nA) and lower supply current consumption (480 µA versus 1 mA total).

Q: Are there packaging differences between these parts?

A: Both parts use identical 14-TSSOP surface-mount packages with 0.173" width and 4.40 mm dimensions. The MCP6H74-E/ST is supplied in Tube packaging, while the TS924IYPT is supplied in Tape & Reel format. This difference affects handling and automated assembly processes but does not impact electrical performance or pin compatibility.

Q: What is the significance of the AEC-Q100 qualification on the TS924IYPT?

A: AEC-Q100 qualification indicates that the TS924IYPT meets automotive industry reliability and quality standards. This qualification is relevant for applications in automotive environments or systems requiring automotive-grade component certification. The MCP6H74-E/ST does not carry this designation.

Q: Which part should be selected for low-power applications?

A: The MCP6H74-E/ST is preferable for low-power applications due to its lower supply current consumption (480 µA total versus 1 mA for the TS924IYPT). This difference becomes significant in battery-powered or energy-constrained systems.

Q: Are both parts suitable for the full -40°C to 125°C temperature range?

A: Yes, both the MCP6H74-E/ST and TS924IYPT are rated for operation across the -40°C to 125°C temperature range. Both maintain active product status and are in current production.
