Substitute Part Grouping Explanation

Substitution of the MAX6250AESA is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Buried Zener
• Output Voltage: Fixed 5V
• Output Current: 15 mA
• Voltage Tolerance: ±0.02%
• Temperature Coefficient: 3 ppm/°C
• Noise Specifications: 3 µVp-p (0.1Hz to 10Hz) and 2.5 µVrms (10Hz to 10kHz)
• Input Voltage Range: 8V ~ 36V
• Operating Temperature Range: -40°C ~ 85°C
• Package: 8-SOIC

The MAX6250AESA+ is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging format, with the MAX6250AESA+ currently in active production.

Parameter Comparison

Engineering Selection Recommendations

The MAX6250AESA+ is the direct substitute for the obsolete MAX6250AESA. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The MAX6250AESA+ is currently in active production status, providing supply chain continuity for applications requiring precision 5V voltage reference functionality.

Selection between these parts is determined by availability and compliance requirements. The MAX6250AESA+ is the preferred choice for new designs and ongoing production due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the MAX6250AESA+ be used as a direct replacement for the MAX6250AESA?

A: Yes. The MAX6250AESA+ is electrically and mechanically identical to the MAX6250AESA. Both components feature the same 5V fixed output, ±0.02% tolerance, 3 ppm/°C temperature coefficient, and 8-SOIC package. No circuit modifications are required for substitution.

Q: What is the difference between MAX6250AESA and MAX6250AESA+?

A: The primary differences are product status and RoHS compliance. The MAX6250AESA is obsolete and RoHS non-compliant, while the MAX6250AESA+ is in active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both the MAX6250AESA and MAX6250AESA+ use the 8-SOIC package with identical pinout and mechanical dimensions (0.154" width, 3.90mm). PCB layout and footprints are fully compatible.

Q: What are the critical parameters for voltage reference substitution?

A: For the MAX6250AESA family, critical parameters include output voltage (5V fixed), voltage tolerance (±0.02%), temperature coefficient (3 ppm/°C), noise specifications (3 µVp-p and 2.5 µVrms), input voltage range (8V ~ 36V), and operating temperature range (-40°C ~ 85°C). All substitute parts must match these specifications exactly.

Q: Is the MAX6250AESA+ suitable for industrial temperature applications?

A: Yes. The MAX6250AESA+ operates across the -40°C ~ 85°C temperature range with a temperature coefficient of 3 ppm/°C, meeting industrial application requirements for precision voltage reference stability.
