Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MX7548JCWP+ are qualified based on the following critical parameters that determine functional equivalence:

• 12-bit resolution with single D/A converter configuration
• Current output, unbuffered topology
• Parallel data interface with external reference capability
• R-2R resistor ladder architecture
• Identical supply voltage ranges (5V, 11.4V ~ 15.75V for both analog and digital)
• Matching INL/DNL specifications (±1 LSB maximum)
• 20-SOIC package footprint compatibility
• Operating temperature range 0°C ~ 70°C
• RoHS3 compliance and MSL Level 1 rating

The substitute parts identified (AD7548JRZ, AD7548JRZ-REEL, AD7548JRZ-REEL7) maintain electrical and mechanical compatibility with the MX7548JCWP+. Differences exist only in packaging format (Tube versus Tape & Reel) and settling time specification (1µs typical for MX7548JCWP+ versus 1.5µs typical for AD7548 variants), which do not affect functional substitution in applications where the specified settling time is acceptable.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active production status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance across industrial and commercial applications. The MX7548JCWP+ and AD7548JRZ variants are electrically and mechanically equivalent, with selection based on packaging requirements and supply availability.

For applications requiring tube packaging with individual component handling, the MX7548JCWP+ and AD7548JRZ are appropriate selections. For high-volume manufacturing or automated assembly processes, the AD7548JRZ-REEL and AD7548JRZ-REEL7 variants in Tape & Reel format provide manufacturing efficiency benefits while maintaining identical electrical performance.

The settling time difference (1µs for MX7548JCWP+ versus 1.5µs typical for AD7548 variants) does not affect substitution suitability in applications where the specified settling time margin is acceptable. Both specifications meet the same maximum INL/DNL tolerance of ±1 LSB, ensuring equivalent conversion accuracy.

Frequently Asked Questions (FAQ)

Q: Can AD7548JRZ replace MX7548JCWP+ in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical 12-bit resolution, R-2R architecture, parallel interface, and 20-SOIC package footprint. The primary difference is packaging format (Tube for both) and settling time specification (1µs versus 1.5µs typical). Substitution is valid where the specified settling time is acceptable.

Q: What is the difference between AD7548JRZ, AD7548JRZ-REEL, and AD7548JRZ-REEL7?

A: These parts are electrically identical 12-bit DACs with matching electrical specifications. The differences are packaging format only: AD7548JRZ is supplied in Tube packaging, while AD7548JRZ-REEL and AD7548JRZ-REEL7 are supplied in Tape & Reel format for automated assembly. Selection depends on manufacturing process requirements and volume handling methods.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The MX7548JCWP+ and all identified substitute parts (AD7548JRZ, AD7548JRZ-REEL, AD7548JRZ-REEL7) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, suitable for standard industrial storage and handling conditions.

Q: Does the settling time difference affect circuit performance?

A: The settling time difference (1µs for MX7548JCWP+ versus 1.5µs typical for AD7548 variants) represents a 0.5µs margin. Substitution is valid in applications where the specified settling time of 1.5µs is acceptable. Applications requiring faster settling time should retain the MX7548JCWP+.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, for the tube and Tape & Reel variants. All parts share identical 20-SOIC package dimensions (0.295", 7.50mm width) and surface mount footprint. Packaging format selection depends on assembly equipment compatibility and handling procedures.

Q: What supply voltage ranges are supported?

A: All substitute parts support identical dual supply voltage ranges: 5V single supply or 11.4V ~ 15.75V dual supply for both analog and digital supplies, enabling flexible power architecture implementation.
