Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX662ACSA is determined by strict equivalence across the following electrical and mechanical parameters:

• Input voltage range: 4.5V to 5.5V
• Output voltage: 12V fixed
• Output current capability: 30mA minimum
• Switching topology: Charge pump
• Package: 8-SOIC form factor
• Mounting: Surface mount
• Operating temperature range: 0°C to 70°C

The MAX662ACSA+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX662ACSA+ is the direct functional equivalent of the MAX662ACSA. Both devices share identical electrical characteristics and package specifications. Selection between these parts should be based on the following criteria:

For new designs and production requiring regulatory compliance, the MAX662ACSA+ is the appropriate choice due to its active product status and RoHS3 compliance certification. This part maintains full electrical and mechanical compatibility while meeting current environmental and regulatory standards.

The MAX662ACSA remains available for legacy system support and repair applications where existing inventory exists. However, the obsolete status of this part indicates limited future availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can MAX662ACSA+ be used as a direct replacement for MAX662ACSA in existing designs?

A: Yes. The MAX662ACSA+ is electrically and mechanically identical to the MAX662ACSA. Both devices operate with the same input voltage range (4.5V to 5.5V), produce the same fixed 12V output, deliver 30mA output current, and use the 8-SOIC package. Pin-for-pin compatibility is maintained.

Q: What is the primary difference between MAX662ACSA and MAX662ACSA+?

A: The MAX662ACSA+ is the active production variant with RoHS3 compliance certification. The MAX662ACSA is classified as obsolete. Electrical performance and package specifications are identical.

Q: Are there any thermal or frequency differences between these parts?

A: No. Both parts operate at 500kHz switching frequency and share the same operating temperature range of 0°C to 70°C. Thermal characteristics and frequency performance are equivalent.

Q: What packaging options are available for these parts?

A: Both the MAX662ACSA and MAX662ACSA+ are supplied in 8-SOIC (0.154", 3.90mm Width) surface mount packages. The MAX662ACSA+ is available in tube packaging, while the MAX662ACSA is supplied as new original stock.

Q: Are moisture sensitivity considerations different between these parts?

A: No. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
