MCP100T-485I/TT Equivalent & Substitute Parts

Part Overview

The MCP100T-485I/TT is a power management integrated circuit functioning as a supervisor with push-pull, totem pole output configuration. This single-channel reset supervisor monitors voltage levels and provides active-low reset signaling in surface-mount SOT-23-3 packaging. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, package compatibility, and operational specifications align with the original component requirements.

Substitute Part Grouping Explanation

Substitution of the MCP100T-485I/TT is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 4.725V (exact match required)
• Output Configuration: Push-Pull, Totem Pole (functional equivalence)
• Reset Logic: Active Low (functional equivalence)
• Reset Timeout: 150ms Minimum (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Type: SOT-23-3 (mechanical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Regulatory Compliance: RoHS3 Compliant, REACH Unaffected (mandatory for equivalent substitution)

The MCP809T-485I/TT qualifies as a parametric equivalent based on identical electrical specifications, package configuration, and regulatory certifications. Both devices function as single-channel supervisors with identical threshold voltage, output topology, and timing characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MCP809T-485I/TT is a direct parametric equivalent to the MCP100T-485I/TT. Both devices maintain active product status with identical electrical specifications, package configuration, and regulatory compliance certifications. Selection between these components is determined by availability and supply chain considerations rather than functional or compliance differences. Both parts satisfy RoHS3 and REACH requirements for applications requiring regulated component sourcing.

Frequently Asked Questions (FAQ)

Q: Can the MCP809T-485I/TT replace the MCP100T-485I/TT in existing designs?

A: Yes. The MCP809T-485I/TT is a parametric equivalent with identical voltage threshold (4.725V), output configuration (push-pull, totem pole), reset logic (active low), reset timeout (150ms minimum), operating temperature range (-40°C to 85°C), and SOT-23-3 package specification. No design modifications are required.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the MCP100T-485I/TT and MCP809T-485I/TT use identical SOT-23-3 surface-mount packaging (TO-236-3, SC-59). Pin configuration and footprint requirements are equivalent.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both devices are RoHS3 compliant and REACH unaffected, meeting identical regulatory standards for restricted substance compliance.

Q: What is the primary difference between these two supervisor ICs?

A: The primary difference is the base product number designation (MCP100 versus MCP809). Electrical performance, package type, and operational specifications are identical. Differences exist only in product line nomenclature and manufacturing series.

Q: Can these parts be used interchangeably in production?

A: Yes. Identical electrical specifications, package configuration, and regulatory compliance certifications support direct interchangeability in manufacturing and assembly processes.
