MCP2155T-I/SO IRDA® Controller Equivalent & Substitute Parts

Part Overview

The MCP2155T-I/SO is an IRDA® Protocol Controller with UART interface manufactured by Microchip Technology. This 18-SOIC packaged integrated circuit operates across a 3V to 5.5V supply range and is designed for infrared communication applications requiring protocol control and UART interfacing. The device is currently in active production status with full ROHS3 compliance and unlimited moisture sensitivity rating. Alternative part sourcing becomes necessary due to inventory availability, packaging format preferences, or supply chain optimization requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP2155T-I/SO is determined by strict equivalence across the following critical parameters:

• IRDA® protocol implementation
• UART interface functionality
• 18-SOIC package form factor with 0.295" (7.50mm) width specification
• Supply voltage range of 3V to 5.5V
• Operating temperature range of -40°C to 125°C
• ROHS3 compliance status
• Microchip Technology manufacturer origin

The primary distinction between the main part and substitute parts lies in packaging format (Tape & Reel versus Tube) and associated HTSUS classifications. These packaging variations do not affect electrical or mechanical compatibility, making them suitable for direct substitution in component-level applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP2155T-I/SO and MCP2155-I/SO are active production devices from Microchip Technology with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on packaging format requirements and supply chain logistics. The Tape & Reel format of the MCP2155T-I/SO is suitable for automated assembly processes, while the Tube packaging of the MCP2155-I/SO accommodates manual handling and smaller volume applications. Both devices maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can MCP2155-I/SO replace MCP2155T-I/SO in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Tape & Reel format is optimized for pick-and-place automation, while Tube format is suitable for manual component handling. PCB design, circuit functionality, and performance remain unchanged.

Q: Are there electrical performance differences between these parts?

A: No. Both parts share identical supply voltage range (3V to 5.5V), current consumption (7mA), operating temperature range (-40°C to 125°C), and IRDA® protocol implementation with UART interface.

Q: What is the significance of the packaging designation in the part number?

A: The "T" in MCP2155T-I/SO indicates Tape & Reel packaging, while MCP2155-I/SO indicates Tube packaging. This affects component delivery format and handling procedures but does not impact electrical or mechanical specifications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the full -40°C to 125°C temperature range, making them suitable for industrial and automotive environments within this specification.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both MCP2155T-I/SO and MCP2155-I/SO are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
