Key Parameters

Substitute Part Grouping Explanation

The MCP3302-CI/ST qualifies as a direct substitute for the MCP3302T-CI/ST based on the following criteria:

Identical Electrical Parameters:

• 13-bit resolution
• 100 kSPS sampling rate
• 2 or 4 input channel configuration
• Differential and single-ended input support
• SPI data interface
• SAR architecture with external reference
• 5V analog and digital supply voltages
• -40°C to 85°C operating temperature range

Identical Mechanical Parameters:

• 14-TSSOP package (0.173", 4.40mm Width)
• Surface mount mounting type

Difference:

• Packaging configuration: MCP3302T-CI/ST supplied in Tape & Reel (TR); MCP3302-CI/ST supplied in Tube

Both parts share the same base product number (MCP3302), active product status, ROHS3 compliance, and MSL rating of 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

Both the MCP3302T-CI/ST and MCP3302-CI/ST are active production devices from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply chain requirements:

• MCP3302T-CI/ST (Tape & Reel): Suitable for high-volume automated assembly operations where tape and reel packaging is required for pick-and-place equipment.

• MCP3302-CI/ST (Tube): Suitable for lower-volume applications, manual assembly, or when tube packaging is preferred for component handling and storage.

Both parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing processes and storage conditions. The choice between these substitutes does not affect circuit design, PCB layout, or firmware implementation.

Frequently Asked Questions (FAQ)

Q: Can MCP3302-CI/ST replace MCP3302T-CI/ST in my design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube vs. Tape & Reel). No circuit modifications are required.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment used in high-volume manufacturing. Tube packaging is used for manual handling and lower-volume applications. Both formats contain the same component in the same 14-TSSOP package.

Q: Are there any compatibility issues with different packaging formats?

A: No. The component itself, pinout, electrical characteristics, and mechanical dimensions are identical. Packaging format only affects how the parts are supplied and handled during assembly.

Q: Do both parts have the same compliance certifications?

A: Yes. Both MCP3302T-CI/ST and MCP3302-CI/ST are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Q: Which part should I choose for my application?

A: Selection depends on your manufacturing process. Use MCP3302T-CI/ST for automated assembly with tape and reel equipment. Use MCP3302-CI/ST for manual assembly or when tube packaging is preferred. Both are functionally equivalent.
