Substitute Part Grouping Explanation

Substitution of the MAX6163BESA is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 3V
• Output current capability of 5 mA
• Voltage tolerance of ±0.17%
• Temperature coefficient of 10 ppm/°C
• Noise specifications (0.1Hz to 10Hz: 35 µVp-p; 10Hz to 10kHz: 40 µVrms)
• Input voltage range of 3.2V to 12.6V
• Supply current of 120 µA
• Operating temperature range of -40°C to 85°C
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Series reference type with fixed output configuration

The MAX6163BESA+ is a direct functional equivalent that maintains all electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX6163BESA+ is the direct substitute for the obsolete MAX6163BESA. Both devices are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status and regulatory compliance:

The MAX6163BESA+ carries Active product status, ensuring ongoing manufacturer support and availability. This part achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new product designs and manufacturing operations. The MAX6163BESA remains RoHS non-compliant and is classified as obsolete, limiting its suitability for new applications.

For applications requiring the 3V fixed reference output with ±0.17% tolerance in an 8-SOIC package, the MAX6163BESA+ provides full functional equivalence with superior supply chain and compliance standing.

Frequently Asked Questions (FAQ)

Q: Can MAX6163BESA+ be used as a direct replacement for MAX6163BESA?

A: Yes. The MAX6163BESA+ is a direct substitute. All electrical specifications, output voltage, current ratings, noise characteristics, temperature range, and package dimensions are identical. The devices are pin-compatible and functionally equivalent.
