Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6241BESA is determined by strict equivalence across the following critical parameters:

• Output Voltage: Must be 4.096V fixed
• Voltage Tolerance: Must be ±0.1%
• Output Current Capability: Must support 15 mA minimum
• Temperature Coefficient: Must be 7 ppm/°C or better
• Noise Performance: Must meet 2.4 µVp-p (0.1Hz to 10Hz) and 2 µVrms (10Hz to 10kHz)
• Input Voltage Range: Must support 8V ~ 36V
• Package: Must be 8-SOIC form factor
• Mounting Type: Must be Surface Mount

Only parts meeting all these criteria are considered direct substitutes. The MAX6241BESA+ variant qualifies as a direct substitute based on identical electrical specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MAX6241BESA+ is the direct substitute for the MAX6241BESA. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status: the MAX6241BESA is Obsolete, while the MAX6241BESA+ is Active.

For new designs and ongoing production, the MAX6241BESA+ is the appropriate selection. It provides ROHS3 compliance, whereas the original MAX6241BESA is RoHS non-compliant. Both parts maintain identical electrical performance, temperature stability, and noise characteristics required for precision voltage reference applications.

Existing designs using the MAX6241BESA can transition to the MAX6241BESA+ without circuit modification, as the parts are pin-compatible and functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can MAX6241BESA+ be used as a direct replacement for MAX6241BESA?

A: Yes. The MAX6241BESA+ is a direct substitute. Both parts have identical output voltage (4.096V), tolerance (±0.1%), output current (15 mA), temperature coefficient (7 ppm/°C), noise specifications, input voltage range (8V ~ 36V), and 8-SOIC package configuration. No circuit modifications are required.

Q: What is the difference between MAX6241BESA and MAX6241BESA+?

A: The parts are electrically and mechanically identical. The primary differences are: (1) Product Status—MAX6241BESA is Obsolete; MAX6241BESA+ is Active; (2) RoHS Compliance—MAX6241BESA is RoHS non-compliant; MAX6241BESA+ is ROHS3 Compliant; (3) Packaging—MAX6241BESA+ is supplied in Tube format.

Q: Are there alternative voltage reference ICs with different output voltages that could substitute?

A: No. Substitution requires exact equivalence in output voltage (4.096V), tolerance (±0.1%), and all electrical specifications. Parts with different output voltages or tolerance ratings are not substitutes and would require circuit redesign.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: fixed output voltage of 4.096V, ±0.1% tolerance, 15 mA output current capability, 7 ppm/°C temperature coefficient, specified noise performance (2.4 µVp-p and 2 µVrms), 8V ~ 36V input range, and 8-SOIC surface mount package. All parameters must match exactly.

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

A: Yes. The package type is a mandatory substitution criterion. The MAX6241BESA and MAX6241BESA+ both use 8-SOIC (0.154", 3.90mm Width) surface mount packaging. Parts in different packages are not compatible without PCB redesign.
