MCP6H94T-E/ST Equivalent & Substitute Parts

Part Overview

The MCP6H94T-E/ST is a general purpose operational amplifier manufactured by Microchip Technology, featuring four independent circuits in a 14-TSSOP surface mount package. This rail-to-rail output amplifier is designed for applications requiring low power consumption and compact form factor. The device is currently in active production status with 969 units available in inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers. The MCP6H94T-E/ST has documented manufacturer-recommended equivalents from Texas Instruments that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP6H94T-E/ST is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Circuits: 4 channels
• Output Type: Rail-to-Rail
• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variation: Substitute parts may differ in slew rate, gain bandwidth product, input bias current, and output current per channel, provided these variations do not violate the application's electrical requirements. Supply voltage span minimum may be lower in substitutes (2.7V vs. 3.5V), which expands operational flexibility. Supply voltage span maximum remains at 12V.

The Texas Instruments TL974IPW and TL974IPWR meet all mandatory matching criteria and are manufacturer-recommended equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All three parts—MCP6H94T-E/ST, TL974IPW, and TL974IPWR—maintain active product status and full ROHS3 compliance with MSL 1 rating, confirming suitability for current manufacturing and long-term reliability requirements.

Packaging and Inventory Considerations:

The TL974IPWR offers the highest inventory availability (21,966 units) with Cut Tape and Digi-Reel® packaging, supporting high-volume production schedules. The TL974IPW provides intermediate availability (2,860 units) in Tube packaging. The MCP6H94T-E/ST is available in Tape & Reel format with 969 units in stock.

Electrical Performance Differences:

The MCP6H94T-E/ST exhibits higher slew rate (10V/µs vs. 5V/µs) and lower input bias current (10pA vs. 200nA), with reduced output current capability per channel (41mA vs. 80mA). The Texas Instruments substitutes provide lower minimum supply voltage (2.7V vs. 3.5V), expanding operational range in low-voltage applications.

Compliance and Regulatory Status:

All parts carry identical REACH Unaffected and EAR99 ECCN classifications, confirming equivalent regulatory standing for export and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can TL974IPW and TL974IPWR be used interchangeably with MCP6H94T-E/ST?

A: Yes, both Texas Instruments parts are manufacturer-recommended equivalents. They share identical circuit count (4), output type (rail-to-rail), package (14-TSSOP), and operating temperature range (-40°C to 125°C). The primary difference is packaging format: TL974IPW uses Tube, while TL974IPWR uses Cut Tape and Digi-Reel®.

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

A: The MCP6H94T-E/ST has higher slew rate (10V/µs) and lower input bias current (10pA). The TL974 series offers higher gain bandwidth product (12MHz vs. 10MHz) and greater output current per channel (80mA vs. 41mA). The TL974 series also supports lower minimum supply voltage (2.7V vs. 3.5V).

Q: Are there supply voltage compatibility concerns?

A: The MCP6H94T-E/ST requires minimum 3.5V supply, while TL974 substitutes operate at 2.7V minimum. Both support 12V maximum. Applications using 2.7V to 3.4V supply require the TL974 series; applications at 3.5V and above support all three parts.

Q: Does packaging format affect electrical performance?

A: No. Tube (TL974IPW) and Cut Tape/Digi-Reel® (TL974IPWR) packaging formats do not alter electrical specifications. Selection depends on assembly line equipment compatibility and inventory management requirements.

Q: Are all three parts RoHS compliant?

A: Yes. MCP6H94T-E/ST, TL974IPW, and TL974IPWR are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: Which part should be selected for high-volume production?

A: TL974IPWR is recommended for high-volume applications due to highest inventory availability (21,966 units) and Cut Tape/Digi-Reel® packaging compatibility with automated assembly equipment.
