MCP6567AT-E/UN Equivalent & Substitute Parts

Part Overview

The MCP6567AT-E/UN is a dual comparator IC manufactured by Microchip Technology, designed for general-purpose comparison applications. The device operates at 1.8V and is packaged in a 10-pin MSOP configuration. With 949 units currently in stock and Active product status, this component remains available for new designs. However, equivalent alternatives from other manufacturers may be required due to supply chain considerations, design flexibility, or specific application requirements.

Substitute Part Grouping Explanation

Substitution for the MCP6567AT-E/UN is determined by functional equivalence in comparator topology and electrical performance characteristics. The TLV3402 series from Texas Instruments provides functional alternatives across multiple package configurations. Substitution validity is based on the following criteria:

• Dual comparator architecture with general-purpose application capability
• CMOS output stage with open-drain configuration
• Supply voltage compatibility within specified ranges
• Input offset voltage and bias current specifications
• Propagation delay performance
• Operating temperature range coverage
• Package compatibility (mechanical and electrical)
• Compliance certifications (RoHS3, REACH, ECCN)

The TLV3402 family offers five distinct part number variants, each differing in packaging format (Tube or Tape & Reel) and package type (8-VSSOP or 8-SOIC), allowing selection based on procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts in the TLV3402 series maintain full compliance with RoHS3, REACH, and EAR99 classifications, ensuring regulatory equivalence with the MCP6567AT-E/UN. Selection among the five TLV3402 variants should be based on the following criteria:

For extended temperature range applications (-40°C to 125°C): TLV3402ID, TLV3402IDGK, or TLV3402IDR are required, as TLV3402CDGK and TLV3402CDGKR are limited to 0°C to 70°C operation.

For packaging format requirements: TLV3402CDGK and TLV3402IDGK are supplied in Tube format, while TLV3402CDGKR and TLV3402IDR are supplied in Tape & Reel format for automated assembly.

For package type compatibility: TLV3402ID and TLV3402IDR use 8-SOIC packaging (0.154" width), while TLV3402CDGK, TLV3402CDGKR, and TLV3402IDGK use 8-VSSOP/8-MSOP packaging (0.118" width). PCB layout modifications may be required when switching between these package types.

For supply continuity: TLV3402IDR maintains Active product status with the highest inventory level (27,578 units), providing the most reliable long-term availability. All other TLV3402 variants are designated Last Time Buy.

Frequently Asked Questions (FAQ)

Q: Can TLV3402 parts directly replace MCP6567AT-E/UN without PCB modifications?

A: Functional replacement is possible, but physical compatibility depends on package selection. The MCP6567AT-E/UN uses a 10-pin MSOP package, while TLV3402 variants use either 8-VSSOP or 8-SOIC packages. PCB layout changes are required for any substitution.

Q: What is the difference between TLV3402CDGK and TLV3402IDGK?

A: Both use identical 8-VSSOP packaging and Tube format. The primary difference is operating temperature range: TLV3402CDGK operates 0°C to 70°C, while TLV3402IDGK operates -40°C to 125°C. Supply voltage ranges also differ slightly (2.5V–16V for CDGK versus 2.7V–16V for IDGK).

Q: Why are some TLV3402 variants marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued or will discontinue production of these specific part numbers. TLV3402IDR (Active status) is the recommended long-term alternative for new designs requiring the 8-SOIC package.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All TLV3402 variants listed maintain ROHS3 Compliant and REACH Unaffected status, matching the MCP6567AT-E/UN compliance profile.

Q: What is the significance of Tape & Reel versus Tube packaging?

A: Tube packaging is suitable for manual assembly or low-volume production. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume manufacturing. Selection depends on production methodology and volume requirements.

Q: Can I use TLV3402CDGK in an application requiring -40°C operation?

A: No. TLV3402CDGK is rated only to 0°C minimum. For extended temperature range applications, use TLV3402ID, TLV3402IDGK, or TLV3402IDR, all rated to -40°C.
