TLC2254CPWR Equivalent & Substitute Parts Reference

Part Overview

The TLC2254CPWR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This LinCMOS™ series device delivers rail-to-rail output capability with low input bias current and is classified as Active product status. The device operates across a 4.4V to 16V supply range and is suitable for applications requiring low-power, general-purpose amplification in compact form factors.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the operational amplifier category, maintaining compatibility with the 14-TSSOP package footprint and surface-mount assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC2254CPWR are identified based on strict equivalence within the following allowed parameters:

Primary Substitution Criteria:

• Package / Case: 14-TSSOP (0.173", 4.40mm Width)
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Mounting Type: Surface Mount
• Category: Linear, Amplifiers (General Purpose)

Secondary Compatibility Parameters:

• Voltage - Supply Span (Min): 3.5V or higher (accommodates TLC2254CPWR minimum of 4.4V)
• Voltage - Supply Span (Max): 16V or higher
• Current - Output / Channel: 50 mA or greater
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The MCP6H04-E/ST and MCP6H04T-E/ST from Microchip Technology satisfy all primary and secondary substitution criteria. Both variants share identical electrical specifications and differ only in packaging format (Tube versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity:

The MCP6H04-E/ST and MCP6H04T-E/ST are valid substitutes for the TLC2254CPWR based on electrical and mechanical parameter equivalence. Both substitute parts maintain the same package footprint (14-TSSOP), circuit count (4), output configuration (rail-to-rail), and mounting technology (surface mount). All three parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, confirming regulatory and environmental compatibility.

Packaging Considerations:

The TLC2254CPWR is supplied in Cut Tape (CT) and Digi-Reel® formats. The MCP6H04-E/ST is supplied in Tube packaging, while the MCP6H04T-E/ST is supplied in Tape & Reel (TR) format. Selection between substitute variants depends on assembly line requirements and tape-and-reel compatibility with pick-and-place equipment.

Product Status:

All three parts maintain Active product status, confirming ongoing manufacturer support and availability.

Compliance Certifications:

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8542.33.0001, ensuring regulatory alignment for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can MCP6H04-E/ST and MCP6H04T-E/ST be used interchangeably with TLC2254CPWR?

A: Yes, both Microchip parts are electrical and mechanical equivalents. The difference between MCP6H04-E/ST and MCP6H04T-E/ST is packaging format only (Tube versus Tape & Reel). Selection depends on assembly process requirements.

Q: What are the key differences in electrical performance between TLC2254CPWR and the MCP6H04 variants?

A: The MCP6H04 series exhibits higher slew rate (0.8V/µs versus 0.12V/µs) and higher gain bandwidth product (1.2MHz versus 210kHz). Input bias current is higher (10pA versus 1pA), and input offset voltage is higher (700µV versus 200µV). These differences do not prevent substitution but should be evaluated for specific application requirements.

Q: Are the operating temperature ranges compatible?

A: The TLC2254CPWR operates from 0°C to 70°C, while MCP6H04-E/ST and MCP6H04T-E/ST operate from -40°C to 125°C. The substitute parts support a wider temperature range, making them suitable for applications requiring extended temperature operation.

Q: Do all three parts fit the same PCB footprint?

A: Yes. All three parts use the 14-TSSOP package with identical dimensions (0.173" width, 4.40mm). PCB layout and footprint design are directly compatible without modification.

Q: What is the difference between MCP6H04-E/ST and MCP6H04T-E/ST?

A: Both parts are electrically identical. MCP6H04-E/ST is supplied in Tube packaging; MCP6H04T-E/ST is supplied in Tape & Reel (TR) format. Choose based on your assembly equipment compatibility and volume requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. TLC2254CPWR, MCP6H04-E/ST, and MCP6H04T-E/ST are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity, confirming environmental and regulatory compatibility.

Q: What supply voltage range is supported?

A: TLC2254CPWR supports 4.4V to 16V. MCP6H04-E/ST and MCP6H04T-E/ST support 3.5V to 16V. The substitute parts accommodate a lower minimum supply voltage, expanding application flexibility.
