Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6250BESA is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Buried Zener
• Output Voltage: Fixed 5V
• Voltage Tolerance: ±0.1%
• Temperature Coefficient: 7 ppm/°C
• Output Current: 15 mA
• Input Voltage Range: 8V ~ 36V
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature Range: -40°C ~ 85°C (TA)

The MAX6250BESA+ meets all electrical and mechanical substitution criteria, maintaining identical functional specifications while differing in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX6250BESA+ is a direct functional equivalent to the MAX6250BESA. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and provide identical electrical performance across all specified parameters.

The primary distinction is product lifecycle status: the MAX6250BESA is obsolete, while the MAX6250BESA+ maintains active production status. Additionally, the MAX6250BESA+ is ROHS3 compliant, whereas the original MAX6250BESA is RoHS non-compliant. For new designs or systems requiring ongoing component availability and regulatory compliance, the MAX6250BESA+ is the appropriate selection. For legacy system maintenance where the original part number is specified, the MAX6250BESA+ provides electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can MAX6250BESA+ be used as a direct replacement for MAX6250BESA?

A: Yes. The MAX6250BESA+ is electrically and mechanically equivalent. Both devices provide identical 5V fixed output voltage, ±0.1% tolerance, 15 mA output current, and 8-SOIC packaging. No circuit modifications are required.

Q: What is the difference between MAX6250BESA and MAX6250BESA+?

A: The devices are functionally identical. The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). The MAX6250BESA+ is the current production variant.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and mechanical dimensions. PCB layout and footprint remain unchanged.

Q: What is the availability difference between these parts?

A: The MAX6250BESA is obsolete with limited remaining inventory. The MAX6250BESA+ is in active production with higher availability. For new procurement, the MAX6250BESA+ is recommended.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental regulations, not electrical specifications. Both parts deliver identical voltage reference performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The MAX6250BESA+ can replace the MAX6250BESA in any application without design changes, provided the system can accommodate the updated RoHS compliance status if required by procurement or regulatory requirements.
