MCP6567A-E/UN Equivalent & Substitute Parts

Part Overview

The MCP6567A-E/UN is a dual comparator IC manufactured by Microchip Technology, designed for general-purpose comparison applications in 1.8V operation environments. The device is packaged in a 10-pin MSOP format and maintains Active product status with full RoHS3 compliance. Given the Active status of this component and the availability of functionally equivalent alternatives from Texas Instruments, substitute parts are identified to provide design flexibility, extended supply chain options, and compatibility across different packaging and operational temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP6567A-E/UN are identified based on functional equivalence as dual comparators with general-purpose CMOS open-drain output architecture. The substitution logic is determined by the following allowed parameters:

• Dual-element comparator configuration (2 independent comparators per IC)
• CMOS open-drain output type
• General-purpose comparator classification
• Surface mount technology
• RoHS3 compliance and REACH unaffected status
• EAR99 export classification
• Identical HTSUS commodity code (8542.39.0001)

The Texas Instruments TLV3402 series (TLV3402CDGK, TLV3402ID, TLV3402IDR) meets these criteria across different packaging options and operational temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection among the MCP6567A-E/UN and its Texas Instruments TLV3402 series substitutes is determined by product lifecycle status, compliance requirements, and packaging constraints:

TLV3402IDR is the primary substitute for new designs requiring Active product status. This part maintains full RoHS3 compliance, REACH unaffected status, and EAR99 classification identical to the MCP6567A-E/UN. The extended operating temperature range (-40°C ~ 125°C) accommodates industrial and automotive applications. The 8-SOIC package requires PCB layout modification from the original 10-MSOP footprint.

TLV3402ID provides an alternative in 8-SOIC packaging with identical electrical specifications to TLV3402IDR but carries Last Time Buy product status, limiting its suitability for long-term production commitments.

TLV3402CDGK offers the closest package compatibility with 8-MSOP form factor, matching the original 10-MSOP pin count consideration. However, this variant operates within a narrower temperature range (0°C ~ 70°C) and carries Last Time Buy status, restricting its application to commercial-grade environments with limited supply availability.

All substitute parts maintain identical compliance certifications (RoHS3, REACH unaffected, EAR99) and moisture sensitivity levels, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can TLV3402 series parts directly replace the MCP6567A-E/UN without PCB modification?

A: Package compatibility varies. TLV3402CDGK uses 8-MSOP packaging, requiring minimal footprint adjustment. TLV3402ID and TLV3402IDR use 8-SOIC packaging, which differs from the original 10-MSOP and requires PCB layout redesign. Pin configuration and functional mapping must be verified against device datasheets before implementation.

Q: What is the significance of "Last Time Buy" product status for TLV3402ID and TLV3402CDGK?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for these parts. Existing inventory remains available, but no future production is planned. For applications requiring long-term supply continuity, TLV3402IDR with Active status is the recommended selection.

Q: Are the electrical performance characteristics of TLV3402 series parts equivalent to MCP6567A-E/UN?

A: The TLV3402 series provides specified electrical parameters (input offset voltage, input bias current, output current, quiescent current, CMRR, PSRR, and propagation delay) that establish functional equivalence as dual general-purpose comparators. The MCP6567A-E/UN detailed electrical specifications are not provided in the reference data; compatibility verification requires comparison against complete device datasheets.

Q: How do operating temperature ranges affect substitution decisions?

A: TLV3402IDR and TLV3402ID support -40°C ~ 125°C operation, suitable for industrial and extended-temperature applications. TLV3402CDGK operates within 0°C ~ 70°C, limiting use to commercial-grade environments. Application temperature requirements must align with the selected substitute part's rated operating range.

Q: Do all substitute parts maintain identical compliance and regulatory status?

A: Yes. All TLV3402 series substitutes maintain RoHS3 compliance, REACH unaffected status, EAR99 export classification, and MSL 1 (Unlimited) moisture sensitivity level, matching the MCP6567A-E/UN specification. Regulatory and environmental compatibility is preserved across all substitute options.
