Substitute Part Grouping Explanation

Substitution for the MAX6350ESA is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Buried Zener
• Output Voltage: Fixed 5V
• Voltage Tolerance: ±0.02%
• Temperature Coefficient: 1.5 ppm/°C
• Noise Performance: 3 µVp-p (0.1Hz to 10Hz) and 2.5 µVrms (10Hz to 10kHz)
• Output Current: 15 mA
• Input Voltage Range: 8V ~ 36V
• Package: 8-SOIC
• Operating Temperature Range: -40°C ~ 85°C

The MAX6350ESA+ meets all electrical and mechanical specifications required for direct substitution. The primary distinction is product status and packaging format, with the MAX6350ESA+ classified as Active and supplied in Tube packaging, compared to the Obsolete status of the original part.

Parameter Comparison

Engineering Selection Recommendations

The MAX6350ESA+ is the direct functional equivalent of the MAX6350ESA. Both parts share identical electrical specifications and mechanical packaging. The MAX6350ESA+ is recommended for new designs and replacement applications due to its Active product status and ROHS3 compliance. The obsolete status of the MAX6350ESA indicates limited future availability; transition to MAX6350ESA+ is appropriate for supply chain continuity and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX6350ESA+ be used as a direct replacement for MAX6350ESA?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output voltage, tolerance, temperature coefficient, noise performance, and 8-SOIC packaging. The primary difference is product status and RoHS compliance.

Q: What is the difference between MAX6350ESA and MAX6350ESA+?

A: The MAX6350ESA+ is the Active production variant with ROHS3 compliance, while the MAX6350ESA is Obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.
