MCP3304-CI/P Equivalent & Substitute Parts

Part Overview

The MCP3304-CI/P is a 13-bit Analog to Digital Converter (ADC) manufactured by Microchip Technology, designed for data acquisition applications requiring moderate resolution and sampling rates. This SAR (Successive Approximation Register) architecture device supports 4 or 8 input channels with both differential and single-ended input configurations, communicating via SPI interface. The part is currently in active production status with 2194 units in stock. Alternative models may be required due to inventory constraints, specific application requirements, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution for the MCP3304-CI/P is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part MCP3304-BI/P maintains identical specifications in the following key areas:

  • Resolution: 13-bit
  • Sampling Rate: 100 kSPS
  • Input Configuration: 4 or 8 channels, differential and single-ended capable
  • Communication Protocol: SPI
  • Supply Voltages: 5V analog and digital
  • Operating Temperature: -40°C to 85°C
  • Package: 16-DIP through-hole
  • Compliance: ROHS3 Compliant

The MCP3304-BI/P differs only in internal temperature grade classification (indicated by the "BI" suffix versus "CI"), which does not affect functional performance within the specified operating temperature range. Both parts are manufactured by Microchip Technology and share identical pinout, electrical characteristics, and application compatibility.

Engineering Selection Recommendations

Both the MCP3304-CI/P and MCP3304-BI/P are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for current and future applications. Selection between these parts should be based on inventory availability and supply chain requirements rather than functional differences. The MCP3304-CI/P offers higher stock availability at 2194 units. The MCP3304-BI/P provides an alternative with 960 units in stock. Both parts maintain identical electrical performance and package specifications, ensuring direct interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can MCP3304-BI/P replace MCP3304-CI/P in existing designs?

A: Yes. Both parts are electrically and mechanically identical within the specified operating temperature range of -40°C to 85°C. The suffix difference (CI versus BI) indicates internal temperature grade classification only and does not affect functional performance or pinout compatibility.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 16-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions. PCB layouts and socket compatibility are identical.

Q: Do both parts support the same input configurations?

A: Yes. Both the MCP3304-CI/P and MCP3304-BI/P support 4 or 8 input channels with differential and single-ended input types. SPI communication protocol and sampling rate (100 kSPS) are identical.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for both variants.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. Both parts are in active production status with equivalent long-term availability.
