Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX1247BCPE+ are identified based on strict parameter equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 12 bits
• Sampling Rate: 133 kSPS
• Number of Inputs: 2, 4 channels
• Input Type: Differential and Single Ended capability
• Data Interface: SPI protocol
• Architecture: SAR topology
• Reference Type: External reference requirement
• Supply Voltage Range: 2.7V ~ 5.25V (both analog and digital)
• Operating Temperature: 0°C ~ 70°C
• Package: 16-DIP (0.300", 7.62mm)
• Mounting: Through Hole

All identified substitute parts maintain complete parameter alignment with the main part number across these specifications, ensuring direct functional and mechanical compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both MAX1247BCPE+ and MAX1247ACPE+ are Active product status components with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and procurement lead times. Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints. Through-hole mounting compatibility ensures direct PCB integration without design modification. Both parts are suitable for applications requiring 12-bit SAR ADC functionality with external reference configuration in the 0°C to 70°C operating range.

Frequently Asked Questions (FAQ)

Q: Can MAX1247ACPE+ be used as a direct replacement for MAX1247BCPE+?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including resolution, sampling rate, input configuration, supply voltage range, operating temperature, and package type. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or regulatory status between these parts?

A: No. Both MAX1247BCPE+ and MAX1247ACPE+ maintain identical RoHS3 compliance, REACH unaffected status, MSL rating, ECCN classification, and HTSUS code.

Q: What is the significance of the package designation 16-DIP (0.300", 7.62mm)?
