Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APX393M8G-13 are qualified based on the following criteria:

Electrical Compatibility Parameters:

• Dual-channel general purpose comparator configuration
• Open-drain output stage capability
• Supply voltage range overlap with 2.5V ~ 5.5V specification
• Input offset voltage, bias current, and propagation delay within acceptable operating margins
• Quiescent current performance suitable for the application

Mechanical Compatibility Parameters:

• 8-pin surface mount package (8-MSOP or 8-SOIC variants)
• 0.118" to 0.154" package width tolerance
• Surface mount mounting type

Compliance Parameters:

• ROHS3 compliance
• Active product status
• EAR99 export classification

The substitute parts MCP6567-E/MS, MCP6567T-E/MS, and TS332IYDT meet these criteria with variations in packaging format and extended operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

MCP6567-E/MS and MCP6567T-E/MS (Microchip Technology): These parts maintain identical 8-MSOP package geometry and pinout compatibility with the APX393M8G-13. Both devices feature extended supply voltage range (1.8V ~ 5.5V) and extended operating temperature range (-40°C ~ 125°C). The primary difference between these two variants is packaging format: MCP6567-E/MS is supplied in Tube packaging, while MCP6567T-E/MS is supplied in Cut Tape with Digi-Reel format. Both achieve ROHS3 compliance and MSL 1 rating. Propagation delay is significantly improved at 80ns versus 600ns for the original part. Input bias current is substantially lower at 1pA. These parts are suitable for applications where extended temperature operation or lower power consumption is beneficial.

TS332IYDT (STMicroelectronics): This part provides an alternative in 8-SOIC package format with 0.154" width, representing a 0.036" increase in package width compared to the 8-MSOP standard. The TS332IYDT operates across 1.6V ~ 5V supply range and -40°C ~ 125°C temperature range. This device features the lowest quiescent current at 26µA and highest output current capability at 93mA. The part includes AEC-Q100 automotive qualification and carries automotive-grade designation. Propagation delay is 720ns, slightly higher than the original APX393M8G-13. Package footprint differences require PCB layout verification before selection.

All substitute parts maintain active product status and ROHS3 compliance, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can MCP6567-E/MS and MCP6567T-E/MS be used interchangeably with APX393M8G-13?

A: Yes, both Microchip parts are pin-compatible and functionally equivalent within the 8-MSOP package. The difference between these two variants is packaging format only: MCP6567-E/MS uses Tube packaging while MCP6567T-E/MS uses Cut Tape with Digi-Reel format. Electrical performance and pinout are identical.

Q: What are the package compatibility considerations for TS332IYDT?

A: The TS332IYDT uses 8-SOIC package format instead of 8-MSOP. While both are 8-pin surface mount packages, the SOIC variant has a larger body width (0.154" versus 0.118"). PCB footprint and layout must be verified for compatibility. Pin assignments should be confirmed against the original design before substitution.

Q: Which substitute part offers the best performance improvement?

A: The MCP6567 variants (both -E/MS and T-E/MS) provide the most significant performance improvement with 80ns propagation delay compared to 600ns for the APX393M8G-13, representing a 7.5x improvement. Input bias current is also substantially reduced from 0.25µA to 1pA. These improvements come with extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C).

Q: Are all substitute parts suitable for automotive applications?

A: Only the TS332IYDT carries AEC-Q100 automotive qualification and automotive-grade designation. The MCP6567 variants and APX393M8G-13 do not include automotive qualification. Application requirements should determine whether automotive-grade components are necessary.

Q: What is the impact of MSL rating differences?

A: The APX393M8G-13 has MSL 3 rating (168 hours maximum floor life), while all substitute parts have MSL 1 rating (unlimited floor life). MSL 1 components offer greater flexibility in storage and handling without moisture bake-out requirements. This represents an advantage for inventory management and supply chain logistics.

Q: Can supply voltage range differences affect circuit operation?

A: The APX393M8G-13 operates from 2.5V ~ 5.5V. MCP6567 variants extend the lower limit to 1.8V, while TS332IYDT operates from 1.6V ~ 5V. If the application operates below 2.5V, only the substitute parts will function. If the application operates within 2.5V ~ 5.5V, all parts are compatible.
