TLC2274ACPW Equivalent & Substitute Parts

Part Overview

The TLC2274ACPW 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 slew rate of 3.6V/µs and a gain bandwidth product of 2.25 MHz, suitable for precision analog signal conditioning and amplification applications. The TLC2274ACPW is classified as obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility while offering active product status and continued manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2274ACPW is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Package type: 14-TSSOP surface-mount configuration
• Pin count and footprint: 14-pin TSSOP (0.173", 4.40mm width)
• Mounting type: Surface mount

Electrical Compatibility:

• Circuit count: Four independent operational amplifier circuits
• Output configuration: Rail-to-rail output capability
• Output current per channel: 50 mA minimum
• Supply voltage range: Minimum 4.4 V to maximum 16 V
• Input bias current: 1 pA maximum
• Input offset voltage: 300 µV maximum
• Slew rate: 3.6 V/µs minimum
• Gain bandwidth product: 2.25 MHz minimum

Compliance & Status:

• RoHS3 compliance
• Moisture sensitivity level: 1 (unlimited)
• Active product status preferred for long-term availability

Substitute parts must satisfy all mechanical and electrical parameters listed above. Packaging format (tube, cut tape, or tape & reel) does not affect functional substitution but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLC2274ACPWR

The TLC2274ACPWR is the direct functional equivalent of the TLC2274ACPW. Both devices are manufactured by Texas Instruments and share identical electrical specifications across all critical parameters: slew rate (3.6 V/µs), gain bandwidth product (2.25 MHz), input bias current (1 pA), input offset voltage (300 µV), and supply current (4.8 mA across four channels). The TLC2274ACPWR maintains active product status, ensuring continued availability and manufacturer support. The only difference is packaging format: TLC2274ACPWR is supplied in cut tape (CT) format rather than tube. This substitute is recommended for applications requiring exact electrical performance matching and long-term supply chain stability.

Secondary Substitutes: MCP6H04-E/ST and MCP6H04T-E/ST

The MCP6H04-E/ST (tube packaging) and MCP6H04T-E/ST (tape & reel packaging) are manufactured by Microchip Technology and provide functional substitution with design trade-offs. Both devices maintain the four-circuit, rail-to-rail configuration in 14-TSSOP packaging and support the full 4.4 V to 16 V supply range. However, these devices exhibit reduced performance in three key parameters: slew rate (0.8 V/µs versus 3.6 V/µs), gain bandwidth product (1.2 MHz versus 2.25 MHz), and input bias current (10 pA versus 1 pA). The MCP6H04 series offers superior power efficiency (135 µA total supply current versus 4.8 mA) and extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). These substitutes are suitable for applications where reduced bandwidth and slew rate are acceptable, and where lower power consumption or extended temperature operation provides system benefits.

All substitute parts maintain RoHS3 compliance, MSL rating 1 (unlimited), and identical mechanical compatibility with the original TLC2274ACPW footprint.

Frequently Asked Questions (FAQ)

Q: Can TLC2274ACPWR be used as a direct replacement for TLC2274ACPW?

A: Yes. The TLC2274ACPWR is electrically identical to the TLC2274ACPW across all specified parameters. Both devices deliver 3.6 V/µs slew rate, 2.25 MHz gain bandwidth product, 1 pA input bias current, and 300 µV input offset voltage. The only difference is packaging format (cut tape versus tube). Both are 14-TSSOP surface-mount devices with identical pin configurations and footprints.

Q: What are the key differences between the TLC2274ACPW and MCP6H04 series?

A: The primary differences are slew rate (3.6 V/µs for TLC2274 versus 0.8 V/µs for MCP6H04), gain bandwidth product (2.25 MHz versus 1.2 MHz), input bias current (1 pA versus 10 pA), and supply current (4.8 mA versus 135 µA). The MCP6H04 series offers lower power consumption and extended temperature range (-40°C to 125°C). Applications requiring high-speed signal conditioning should use TLC2274ACPWR. Applications prioritizing power efficiency or extended temperature operation may use MCP6H04 variants.

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

A: Yes, electrically and mechanically. Both are identical MCP6H04 devices with the same electrical specifications. 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 procurement and assembly requirements.

Q: What is the impact of reduced slew rate in MCP6H04 substitutes?

A: Slew rate determines the maximum rate of voltage change at the output. The MCP6H04 slew rate of 0.8 V/µs is lower than the TLC2274ACPW specification of 3.6 V/µs. This limits the maximum frequency and amplitude of output signal transitions. Applications with high-frequency or high-amplitude transient requirements should retain the TLC2274ACPWR. Applications with slower signal conditioning requirements are unaffected by this difference.

Q: Do all substitute parts maintain the same 14-TSSOP footprint?

A: Yes. All substitute parts—TLC2274ACPWR, MCP6H04-E/ST, and MCP6H04T-E/ST—use the 14-TSSOP package with 0.173" width (4.40 mm). Pin count, spacing, and mechanical dimensions are identical. PCB layout and assembly processes require no modification.

Q: Are there supply voltage compatibility concerns with MCP6H04 substitutes?

A: No. The MCP6H04 series supports a minimum supply voltage of 3.5 V, which is lower than the TLC2274ACPW minimum of 4.4 V. Both devices support the maximum 16 V supply. Systems designed for 4.4 V to 16 V operation are fully compatible with MCP6H04 substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All parts—TLC2274ACPW, TLC2274ACPWR, MCP6H04-E/ST, and MCP6H04T-E/ST—are RoHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity), and are REACH unaffected. All meet ECCN EAR99 classification and HTSUS code 8542.33.0001.
