Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6225ACSA is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Buried Zener
• Output Voltage: 2.5V (Fixed)
• Output Current: 15 mA minimum
• Voltage Tolerance: ±0.04%
• Temperature Coefficient: 2 ppm/°C
• Noise Performance: 1.5 µVp-p (0.1Hz to 10Hz) and 1.3 µVrms (10Hz to 10kHz)
• Input Voltage Range: 8V to 36V
• Package: 8-SOIC Surface Mount

Only parts meeting all these specifications are classified as direct substitutes. Packaging format (Tube vs. standard packaging) does not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX6225ACSA+ is a direct electrical and mechanical equivalent to the MAX6225ACSA. Both parts are identical in all functional parameters, electrical performance, and package specifications. The primary distinction is product lifecycle status: the original MAX6225ACSA is Obsolete, while the MAX6225ACSA+ maintains Active status with current manufacturing support.

The MAX6225ACSA+ additionally meets ROHS3 compliance requirements, whereas the original part is non-compliant. For new designs or systems requiring regulatory compliance with modern environmental standards, the MAX6225ACSA+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, both parts provide identical electrical performance.

Frequently Asked Questions (FAQ)

Q: Are MAX6225ACSA and MAX6225ACSA+ electrically interchangeable?

A: Yes. Both parts provide identical electrical performance across all specified parameters including output voltage, tolerance, temperature coefficient, noise characteristics, and operating ranges. They are pin-compatible and functionally equivalent.

Q: What is the difference between MAX6225ACSA and MAX6225ACSA+?

A: The parts are electrically identical. The primary differences are product status (Obsolete vs. Active) and RoHS compliance (Non-compliant vs. ROHS3 Compliant). The MAX6225ACSA+ is supplied in Tube packaging format.

Q: Can I use MAX6225ACSA+ as a replacement for MAX6225ACSA in existing designs?

A: Yes. The MAX6225ACSA+ is a direct substitute with identical electrical specifications and 8-SOIC package configuration. No circuit modifications are required.

Q: Are there any package or mounting differences?

A: Both parts use the same 8-SOIC (0.154", 3.90mm Width) Surface Mount package. Packaging format (Tube) does not affect electrical compatibility or PCB mounting procedures.

Q: Which part should I specify for new designs?

A: The MAX6225ACSA+ is recommended for new designs due to its Active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.
