Engineering Selection Recommendations

TLC2264CPWR (Texas Instruments)

The TLC2264CPWR is the manufacturer-recommended direct substitute for the discontinued TLC2264CPWRG4. This part maintains identical electrical specifications across all parameters, including slew rate, gain bandwidth product, supply current, and input characteristics. The device is currently in active production status with substantial inventory availability (12,978 pcs). Packaging differs only in format (Cut Tape & Digi-Reel® versus the original packaging), with no impact on component functionality or PCB assembly compatibility. ROHS3 compliance and MSL rating are identical. This part is the preferred selection for direct replacement in existing designs.

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

The MCP6H04 series from Microchip Technology provides functional equivalence with enhanced performance characteristics. Both variants (tube packaging for MCP6H04-E/ST and tape & reel for MCP6H04T-E/ST) deliver superior slew rate (0.8 V/µs versus 0.55 V/µs) and higher gain bandwidth product (1.2 MHz versus 730 kHz). The extended operating temperature range (-40°C ~ 125°C) exceeds the original specification. Supply current is significantly reduced (135 µA versus 850 µA), providing power efficiency benefits. Input bias current is higher (10 pA versus 1 pA) and input offset voltage is increased (700 µV versus 300 µV), representing measurable but acceptable deviations for general-purpose amplifier applications. Both parts maintain ROHS3 compliance, MSL rating 1, and active production status. Selection between MCP6H04-E/ST and MCP6H04T-E/ST depends on packaging requirements for assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TLC2264CPWR be used as a direct replacement for TLC2264CPWRG4?

A: Yes. The TLC2264CPWR is electrically and mechanically identical to the TLC2264CPWRG4. All electrical parameters, package dimensions, and pin configurations are equivalent. The only difference is packaging format (Cut Tape & Digi-Reel® versus original packaging). This part is the manufacturer-recommended substitute.

Q: What are the key differences between TLC2264CPWRG4 and MCP6H04 series?

A: The MCP6H04 series offers higher slew rate (0.8 V/µs versus 0.55 V/µs), higher gain bandwidth product (1.2 MHz versus 730 kHz), lower supply current (135 µA versus 850 µA), and extended operating temperature range (-40°C ~ 125°C versus 0°C ~ 70°C). Input bias current is higher (10 pA versus 1 pA) and input offset voltage is increased (700 µV versus 300 µV). All parts share identical package type (14-TSSOP), four-circuit configuration, and rail-to-rail output capability.

Q: Are MCP6H04-E/ST and MCP6H04T-E/ST interchangeable?

A: Yes, from an electrical and functional perspective. Both parts have identical electrical specifications. The difference is packaging format: MCP6H04-E/ST is supplied in tubes, while MCP6H04T-E/ST is supplied in tape & reel format. Selection depends on assembly process requirements and inventory management practices.

Q: Will substituting MCP6H04 for TLC2264CPWRG4 affect circuit performance?

A: The MCP6H04 series will function in circuits designed for TLC2264CPWRG4 operation. Performance differences include faster slew rate and higher bandwidth, which are generally beneficial. The higher input offset voltage (700 µV versus 300 µV) and input bias current (10 pA versus 1 pA) may require evaluation in precision analog applications with tight offset specifications. Power consumption is significantly reduced.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC2264CPWR, MCP6H04-E/ST, and MCP6H04T-E/ST are all ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). All parts meet current environmental and regulatory requirements.

Q: What is the difference between Cut Tape & Digi-Reel® and Tape & Reel packaging?

A: Both are surface-mount compatible formats. Cut Tape & Digi-Reel® (TLC2264CPWR) provides flexibility for smaller quantity orders and manual assembly. Tape & Reel (MCP6H04T-E/ST) is optimized for high-volume automated assembly processes. Component functionality is identical; packaging selection depends on production volume and assembly equipment.

Q: Can I use MCP6H04-E/ST (tube packaging) in automated assembly?

A: Tube packaging is designed for manual or semi-automated handling. For fully automated pick-and-place assembly, tape & reel format (MCP6H04T-E/ST) is the standard requirement. Verify assembly equipment compatibility before selecting tube-packaged components.

Q: Is the TLC2264CPWRG4 still available for purchase?

A: The TLC2264CPWRG4 is discontinued at DiGi Electronics. The manufacturer-recommended substitute TLC2264CPWR is in active production with 12,978 pcs in stock. Alternative suppliers may maintain limited discontinued inventory, but new designs should specify TLC2264CPWR or MCP6H04 series for long-term availability assurance.
