Key Parameters

Substitute Part Grouping Explanation

Substitution for the MX7847J/D is determined by the following critical parameters:

• Functional equivalence: 12-bit resolution digital to analog converter architecture
• Output configuration: Voltage output with buffering capability
• Data interface: Parallel interface for digital input
• Supply voltage compatibility: External reference type with specified analog supply voltage range
• Package compatibility: Surface mount packaging suitable for the original application
• Regulatory compliance: RoHS3 compliance and REACH unaffected status maintained
• Manufacturer lineage: Parts from Analog Devices Inc./Maxim Integrated product families

The substitute part MX7847JR+ meets all these criteria as an active production equivalent within the same manufacturer's DAC product line.

Parameter Comparison

Engineering Selection Recommendations

The MX7847JR+ is the primary substitute for the obsolete MX7847J/D based on the following engineering criteria:

• Active production status: The MX7847JR+ is in active production, ensuring long-term availability and manufacturer support, whereas the MX7847J/D is obsolete with no ongoing supply.
• Regulatory compliance alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.
• Moisture sensitivity equivalence: Both parts share MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.
• Manufacturer continuity: Both parts originate from Analog Devices Inc./Maxim Integrated, ensuring consistent quality standards and technical documentation.
• Surface mount compatibility: The MX7847JR+ maintains surface mount technology, compatible with existing PCB assembly processes.

Selection of the MX7847JR+ eliminates obsolescence risk while preserving functional and compliance characteristics of the original design.

Frequently Asked Questions (FAQ)

Q: Can the MX7847JR+ directly replace the MX7847J/D in existing designs?
