MAX6161BESA+ Equivalent & Substitute Parts

Part Overview

The MAX6161BESA+ is a series voltage reference integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This component provides a fixed 1.25V output with ±0.32% tolerance and is designed for precision analog applications requiring stable reference voltages. The device is currently in active production status and is widely used in power management and signal conditioning circuits. Alternative components may be required due to supply constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6161BESA+ is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.25V
• Output current capability of 5 mA minimum
• Tolerance specification of ±0.32% or better
• Temperature coefficient of 15 ppm/°C or lower
• Input voltage range of 2.5V ~ 12.6V minimum
• 8-SOIC surface mount package configuration
• Series voltage reference topology
• Active product status with current manufacturing support

Only components meeting all of these criteria simultaneously qualify as direct substitutes. Deviations in any parameter eliminate substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX6161BESA+ is an active product with full manufacturing support and ROHS3 compliance certification. When selecting this component or evaluating alternatives, prioritize parts with identical electrical specifications and 8-SOIC packaging to ensure direct circuit compatibility. The ROHS3 compliance status and MSL Level 1 rating confirm suitability for standard manufacturing and storage conditions without special handling requirements. Supply chain decisions should be based on inventory availability and lead time rather than performance differentiation, as equivalent parts meeting all specified parameters deliver identical circuit performance.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct substitute for the MAX6161BESA+?

A: A direct substitute must match all electrical parameters: 1.25V fixed output, 5 mA output current, ±0.32% tolerance, 15 ppm/°C temperature coefficient, 2.5V to 12.6V input range, and 150 µA supply current. The package must be 8-SOIC surface mount, and the product must maintain active manufacturing status.

Q: Can I use a different output voltage reference in place of the MAX6161BESA+?

A: No. The 1.25V fixed output is a core functional requirement. Components with different output voltages are not substitutes and require circuit redesign.

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

A: Yes. The 8-SOIC package is a mandatory requirement for direct substitution. Different packages require PCB layout changes and are not considered equivalent.

Q: What is the significance of the ±0.32% tolerance specification?

A: The tolerance specification defines the maximum allowable deviation from the nominal 1.25V output voltage. Substitute parts must meet or exceed this tolerance requirement to maintain circuit performance specifications.

Q: Does ROHS3 compliance affect substitution eligibility?

A: ROHS3 compliance is a regulatory and manufacturing requirement. All substitute parts must maintain equivalent compliance status for production and supply chain compatibility.

Q: Can I substitute based on similar but not identical temperature coefficients?

A: No. The 15 ppm/°C temperature coefficient is a specified performance parameter. Substitutes must match this value to ensure equivalent thermal stability across the operating temperature range.
