TLV274CPWRG4 Equivalent & Substitute Parts

Part Overview

The TLV274CPWRG4 is a general-purpose operational amplifier featuring four independent circuits in a 14-TSSOP surface-mount package. This device delivers rail-to-rail output capability with a 3 MHz gain-bandwidth product and operates across a 2.7 V to 16 V supply range. The TLV274CPWRG4 is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements when the original part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV274CPWRG4 is determined by strict electrical and mechanical compatibility across the following criteria:

Primary Substitution Criteria:

• Four independent operational amplifier circuits
• Rail-to-rail output configuration
• 14-TSSOP surface-mount package with identical 0.173" (4.40mm) width
• Supply voltage range compatibility (minimum 2.7 V, maximum 16 V)
• General-purpose amplifier classification

Secondary Compatibility Factors:

• Slew rate performance (2.6 V/µs baseline)
• Gain-bandwidth product (3 MHz baseline)
• Input bias current (1 pA baseline)
• Input offset voltage (500 µV baseline)
• Output current per channel (8 mA baseline)
• Total supply current (550 µA across four channels)

Substitute parts must maintain identical package geometry and pinout to ensure direct board-level replacement without layout modification. Electrical parameter variations are acceptable when the substitute part meets or exceeds the performance envelope required by the application circuit.

Engineering Selection Recommendations

TLV274CPWR (Texas Instruments)

The TLV274CPWR is the direct manufacturer-recommended substitute for the obsolete TLV274CPWRG4. Both parts share identical electrical specifications, including 2.6 V/µs slew rate, 3 MHz gain-bandwidth product, 1 pA input bias current, and 500 µV input offset voltage. The TLV274CPWR maintains the same 2.7 V to 16 V supply range and 0°C to 70°C operating temperature window. This part is currently in active production status with 22,000 units in stock. The TLV274CPWR is available in Cut Tape and Digi-Reel packaging options. Selection of this part ensures electrical and thermal performance equivalence with zero design modification required. ROHS3 compliance and MSL 1 rating are maintained.

MCP6H04-E/ST and MCP6H04T-E/ST (Microchip Technology)

The MCP6H04 series from Microchip Technology provides functional substitution with notable performance trade-offs. Both MCP6H04-E/ST (Tube packaging) and MCP6H04T-E/ST (Tape & Reel packaging) deliver four rail-to-rail operational amplifier circuits in identical 14-TSSOP package geometry. The MCP6H04 series exhibits reduced slew rate (0.8 V/µs versus 2.6 V/µs) and lower gain-bandwidth product (1.2 MHz versus 3 MHz). Input bias current increases to 10 pA, and input offset voltage rises to 700 µV. Supply current consumption decreases to 135 µA across four channels, and output current per channel increases to 50 mA. The minimum supply voltage requirement increases to 3.5 V, eliminating compatibility with 2.7 V supply designs. Operating temperature range extends to -40°C to 125°C. These parts are active production items with 2,918 units (MCP6H04-E/ST) and 3,800 units (MCP6H04T-E/ST) in inventory. Selection of MCP6H04 variants requires circuit validation to confirm that reduced bandwidth and slew rate performance remain acceptable for the target application. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can TLV274CPWR be used as a direct replacement for TLV274CPWRG4 without circuit modification?

A: Yes. The TLV274CPWR is electrically and mechanically identical to the TLV274CPWRG4. All electrical parameters, package dimensions, pinout, and supply voltage ranges are equivalent. No circuit redesign or board layout changes are required.

Q: What are the key differences between TLV274CPWR and MCP6H04 series?

A: The primary differences are slew rate (2.6 V/µs versus 0.8 V/µs), gain-bandwidth product (3 MHz versus 1.2 MHz), input bias current (1 pA versus 10 pA), input offset voltage (500 µV versus 700 µV), and minimum supply voltage (2.7 V versus 3.5 V). The MCP6H04 series offers higher output current per channel (50 mA versus 8 mA) and lower total supply current (135 µA versus 550 µA). Operating temperature range is extended on the MCP6H04 series (-40°C to 125°C versus 0°C to 70°C).

Q: Can MCP6H04 variants be used in applications designed for TLV274CPWRG4?

A: MCP6H04 substitution requires circuit validation. Applications requiring 2.7 V minimum supply voltage cannot use MCP6H04 parts due to the 3.5 V minimum requirement. Applications sensitive to slew rate or bandwidth performance must confirm that 0.8 V/µs slew rate and 1.2 MHz bandwidth are acceptable. Input offset voltage and bias current specifications differ and may affect precision analog circuits.

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

A: Both parts are electrically identical. The difference is packaging format: MCP6H04-E/ST is supplied in Tube packaging, while MCP6H04T-E/ST is supplied in Tape & Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLV274CPWR, MCP6H04-E/ST, and MCP6H04T-E/ST are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the recommended substitute if 2.7 V minimum supply voltage is required?

A: TLV274CPWR is the only substitute that maintains 2.7 V minimum supply voltage compatibility. MCP6H04 variants require minimum 3.5 V supply and are not suitable for 2.7 V applications.

Q: Can these parts be used interchangeably in production?

A: TLV274CPWR can be used interchangeably with TLV274CPWRG4 without qualification. MCP6H04 variants require design review and circuit validation before production implementation due to performance parameter differences.
