Substitute Part Grouping Explanation

Substitute parts for the MAX19693EXW-D are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

• Resolution and Converter Count: 12-bit resolution with 1 D/A converter
• Timing Performance: 4.5 ns settling time (typical)
• Signal Interface: LVDS parallel data interface with external reference
• Power Supply Requirements: Dual supply voltages (analog: 3.1V–3.5V, digital: 1.7V–1.9V)
• Linearity Specifications: INL/DNL of ±1.2 LSB and ±0.8 LSB
• Output Architecture: Current sink, unbuffered voltage output
• Thermal Range: -40°C to 85°C operating temperature
• Package Specification: 169-CSBGA (11x11) ball grid array
• Compliance: ROHS3 and REACH compliance status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Engineering Selection Recommendations

The MAX19693EXW+D is a direct parametric equivalent to the MAX19693EXW-D. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts should be based on:

1. Availability: The MAX19693EXW-D maintains higher inventory (892 pcs) compared to MAX19693EXW+D (671 pcs).
2. Product Status: Both parts are Active and suitable for new designs and production applications.
3. Compliance: Both parts meet ROHS3 and REACH requirements, ensuring regulatory compliance for industrial and commercial applications.
4. Packaging and Thermal: Identical 169-CSBGA (11x11) package and MSL rating ensure no redesign or requalification is required for PCB assembly processes.

No performance degradation occurs when substituting between these parts. The selection is driven by supply chain considerations and inventory availability rather than technical differentiation.

Frequently Asked Questions (FAQ)

Q1: Can MAX19693EXW+D replace MAX19693EXW-D in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, and package dimensions. No circuit modifications or PCB layout changes are required.

Q2: Are there differences in settling time or linearity between these parts?

A: No. Both parts specify 4.5 ns settling time (typical) and identical INL/DNL specifications of ±1.2 LSB and ±0.8 LSB. Performance is equivalent across all timing and accuracy parameters.

Q3: Do both parts require the same power supply configuration?

A: Yes. Both the MAX19693EXW-D and MAX19693EXW+D require dual supply voltages: analog supply of 3.1V to 3.5V and digital supply of 1.7V to 1.9V. Power distribution and decoupling schemes remain unchanged.

Q4: Is the 169-CSBGA (11x11) package identical for both parts?

A: Yes. Both parts use the same 169-CSBGA (11x11) ball grid array package with identical pin assignments, ball pitch, and mechanical dimensions. PCB footprints and assembly processes are interchangeable.

Q5: What is the difference between the part numbers MAX19693EXW-D and MAX19693EXW+D?

A: The difference is in the suffix designation (-D versus +D), which represents different packaging or lead finish options from the manufacturer. All electrical and functional specifications remain identical.

Q6: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -40°C to 85°C temperature range and maintain specified performance within this range. MSL rating of 3 (168 hours) applies to both parts for moisture sensitivity considerations during storage and assembly.

Q7: Do these parts require external reference voltage?

A: Yes. Both the MAX19693EXW-D and MAX19693EXW+D require an external reference voltage. The reference type is External for both parts, requiring a precision voltage source in the application circuit.

Q8: Can these parts be used interchangeably in production?

A: Yes. Both parts are Active product status with ROHS3 and REACH compliance. They are suitable for production use and can be substituted based on supply availability without requiring design changes or requalification.
