Substitute Part Grouping Explanation
Substitution for the MAX6198BESA is determined by the following critical parameters:
- Fixed output voltage of 4.096V
- 8-SOIC package compatibility
- Tolerance specification (±0.12% or better)
- Operating temperature range (-40°C to 85°C minimum)
- Input voltage range compatibility (4.296V to 12.6V minimum)
The MAX6198BESA+ is a direct packaging variant with identical electrical specifications but active product status and improved RoHS compliance. The ADR292 series (ADR292ERZ, ADR292FRZ, ADR292GRZ variants) and ADR4540 series provide enhanced performance alternatives with tighter tolerances, lower temperature coefficients, and extended temperature ranges, all maintaining the same 4.096V output and 8-SOIC package format.

Engineering Selection Recommendations
For direct replacement of the MAX6198BESA in existing designs, the MAX6198BESA+ is the primary choice. It maintains identical electrical specifications and 8-SOIC packaging while offering active product status and ROHS3 compliance, eliminating obsolescence risk.
For new designs or applications requiring enhanced performance, the ADR292 series provides tighter tolerance specifications (±0.07% to ±0.15%) and extended operating temperature range (-40°C to 125°C). The ADR292FRZ and ADR292FRZ-REEL7 match the MAX6198BESA tolerance of ±0.1% while offering improved temperature stability and higher output current capability (5 mA versus 500 µA).
The ADR4540 series represents the highest performance option with exceptional tolerance (±0.02% to ±0.04%), minimal temperature coefficient (2 to 4 ppm/°C), and 10 mA output current. This series is suitable for precision measurement and calibration applications.
All substitute parts maintain the 4.096V fixed output voltage and 8-SOIC package format. All active alternatives are ROHS3 compliant, addressing regulatory requirements for new production.
Frequently Asked Questions (FAQ)
Q: Can ADR292 series parts directly replace the MAX6198BESA?
A: Yes, with design considerations. The ADR292 series maintains the 4.096V output and 8-SOIC package. However, output current is 5 mA versus 500 µA for the MAX6198BESA. Input voltage range differs (5V to 15V for ADR292 versus 4.296V to 12.6V for MAX6198BESA). Verify your circuit's input voltage and load current requirements before substitution.
Q: What is the difference between ADR292ERZ, ADR292FRZ, and ADR292GRZ?
A: These parts differ in tolerance and temperature coefficient specifications. ADR292ERZ offers ±0.07% tolerance with 8 ppm/°C temperature coefficient. ADR292FRZ provides ±0.1% tolerance with 15 ppm/°C temperature coefficient. ADR292GRZ has ±0.15% tolerance with 25 ppm/°C temperature coefficient. Select based on your precision requirements.
Q: What packaging options are available for the ADR292 series?
A: The ADR292 series is available in Tube packaging (ADR292ERZ, ADR292FRZ, ADR292GRZ) and Cut Tape with Digi-Reel packaging (ADR292ERZ-REEL, ADR292FRZ-REEL7, ADR292GRZ-REEL7). Packaging choice depends on your assembly process and volume requirements.
Q: Is the ADR4540 series suitable for replacing the MAX6198BESA?
A: The ADR4540 series is compatible in package and output voltage but offers significantly higher performance specifications. It provides superior tolerance (±0.02% to ±0.04%), lower temperature coefficient (2 to 4 ppm/°C), and higher output current (10 mA). Use ADR4540 when precision requirements exceed the MAX6198BESA specification or when extended temperature range (-40°C to 125°C) is required.
Q: Are all substitute parts RoHS compliant?
A: The MAX6198BESA is RoHS non-compliant. All active substitute parts listed (MAX6198BESA+, ADR292 series, ADR4540 series) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.
Q: What is the minimum input voltage requirement for each substitute?
A: MAX6198BESA and MAX6198BESA+ require 4.296V minimum input. ADR292 series requires 5V minimum input. ADR4540 series requires 4.2V minimum input. Ensure your power supply meets these requirements for proper operation.
