MAX1247ACPE Equivalent & Substitute Parts

Part Overview

The MAX1247ACPE is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. The device features 2 or 4 differential/single-ended inputs, SPI data interface, and operates across a 2.7V to 5.25V supply range. The MAX1247ACPE is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Engineering Selection Recommendations

MAX1247ACPE+ is the direct equivalent substitute, maintaining identical electrical and mechanical specifications while offering active product status and RoHS3 compliance. This part is suitable for applications requiring direct replacement with modern regulatory compliance.

MAX1247BCPE+ is a parametric equivalent offering identical functional specifications and active product status with RoHS3 compliance. Selection between MAX1247ACPE+ and MAX1247BCPE+ depends on specific temperature grade or performance grade requirements defined by the base product number suffix.

Both substitute parts are available in tube packaging and provide superior compliance posture compared to the obsolete MAX1247ACPE, which carries RoHS non-compliant status.

Frequently Asked Questions (FAQ)

Q: Can MAX1247ACPE+ directly replace MAX1247ACPE in existing designs?

A: Yes. MAX1247ACPE+ maintains identical electrical specifications, pin configuration, package dimensions, and functional performance. No circuit modifications are required for direct substitution.

Q: What is the difference between MAX1247ACPE+ and MAX1247BCPE+?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the base product number suffix, which may indicate different temperature grades or performance grades. Consult the device datasheet for specific grade definitions.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MAX1247ACPE+ and MAX1247BCPE+ are RoHS3 compliant, whereas the original MAX1247ACPE is RoHS non-compliant. This compliance improvement is significant for applications subject to RoHS regulations.

Q: Is the 16-DIP through-hole package identical across all three parts?

A: Yes. All three parts use the same 16-DIP (0.300", 7.62mm) through-hole package with identical pin assignments and mechanical dimensions.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of product availability and compliance requirements. MAX1247ACPE+ and MAX1247BCPE+ are both active products with confirmed inventory, making them suitable for ongoing production use.
