Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX6350CPA+ is determined by strict equivalence across the following critical parameters:

• Output voltage specification (5V fixed)
• Voltage tolerance (±0.02%)
• Temperature coefficient (1 ppm/°C)
• Output current capability (15 mA minimum)
• Input voltage range compatibility (8V ~ 36V)
• Package form factor (8-DIP through-hole)
• Reference type (Series, Buried Zener)
• Noise performance specifications
• Operating temperature range (0°C ~ 70°C minimum)
• Compliance certifications (RoHS3, REACH Unaffected)

Only components meeting all these parameters qualify as direct substitutes. The MAX6350CPA+ itself represents the complete substitute list for this application requirement.

Parameter Comparison

Engineering Selection Recommendations

The MAX6350CPA+ is the specified component for applications requiring a 5V precision voltage reference with ±0.02% tolerance in an 8-DIP through-hole package. Given its Obsolete product status, inventory availability becomes a critical consideration for procurement planning.

Current stock of 2032 pieces is available as New Original. The component maintains full RoHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements for industrial and commercial applications.

For new designs or system replacements where the MAX6350CPA+ cannot be sourced, alternative 5V reference ICs from Analog Devices or other manufacturers must be evaluated against the complete parameter set specified above. Any deviation in tolerance, temperature coefficient, noise performance, or package form factor constitutes a design change requiring full validation.

Frequently Asked Questions (FAQ)

Q: Can I substitute the MAX6350CPA+ with a different voltage reference IC?

A: Only components providing identical 5V output, ±0.02% tolerance, 1 ppm/°C temperature coefficient, and 8-DIP through-hole packaging qualify as direct substitutes. Different output voltages or tolerance specifications require circuit redesign and validation.

Q: What makes the MAX6350CPA+ suitable for precision applications?

A: The combination of ±0.02% voltage tolerance, 1 ppm/°C temperature coefficient, and low noise specifications (3 µVp-p at 0.1Hz to 10Hz, 2.5 µVrms at 10Hz to 10kHz) enables use in precision analog measurement and calibration circuits.

Q: Is the 8-DIP package critical for substitution?

A: Yes. The 8-DIP (0.300", 7.62mm) through-hole package is a fixed requirement for board-level compatibility. Surface-mount alternatives or different pin counts are not compatible without PCB redesign.

Q: Does the MAX6350CPA+ meet current compliance standards?

A: The component is ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for industrial electronics manufacturing and deployment.

Q: What is the significance of the Obsolete product status?

A: Obsolete status indicates the manufacturer no longer produces this component. Existing inventory must be carefully managed for ongoing system support. Future designs should evaluate current-production alternatives meeting the same electrical and mechanical specifications.

Q: Can the MAX6350CPA+ operate outside the 0°C to 70°C temperature range?

A: No. The specified operating temperature range is 0°C to 70°C. Applications requiring extended temperature operation require alternative components rated for the required temperature range.
