Substitute Part Grouping Explanation

Substitution of the MAX5024MASA is determined by strict equivalence across the following critical parameters:

Output configuration (Positive)
Output type (Adjustable/Fixed)
Number of regulators (1)
Maximum input voltage (65V)
Output voltage range (2.5V to 11V)
Maximum dropout voltage (1.5V @ 150mA)
Output current capability (150mA)
Quiescent current (140 µA)
Control features (Enable, Hold, Reset)
Protection features (Over Temperature, Short Circuit)

Engineering Selection Recommendations

The MAX5024MASA+ is the direct substitute for the obsolete MAX5024MASA. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The MAX5024MASA+ carries active product status from Analog Devices Inc./Maxim Integrated, providing ongoing manufacturing support and availability.

Both variants comply with ROHS3 requirements and maintain REACH unaffected status, satisfying regulatory compliance requirements for current production environments. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Selection of the MAX5024MASA+ is appropriate for new designs and production continuity where the MAX5024MASA is no longer available. Electrical performance, thermal characteristics, and control functionality remain equivalent across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can the MAX5024MASA+ be used as a direct replacement for the MAX5024MASA?

A: Yes. The MAX5024MASA+ is electrically and mechanically equivalent to the MAX5024MASA. Both parts share identical output configurations, voltage ratings, current capabilities, control features, protection mechanisms, and 8-SOIC package specifications. The primary difference is product status; the MAX5024MASA+ is actively manufactured.

Q: What is the significance of the "+" designation in MAX5024MASA+?

A: The "+" designation indicates the active production variant of the MAX5024 base product number. This notation distinguishes the currently available part from the obsolete MAX5024MASA.

Q: Are there packaging differences between MAX5024MASA and MAX5024MASA+?

A: Both parts use the same 8-SOIC (0.154", 3.90mm Width) package with exposed pad. The MAX5024MASA+ is supplied in Tube packaging format, while the original MAX5024MASA packaging format is not specified in the provided data.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching output configuration (Positive), output type (Adjustable/Fixed), single regulator topology, 65V maximum input voltage, 2.5V to 11V output voltage range, 150mA output current, 1.5V maximum dropout voltage, control features (Enable, Hold, Reset), protection features (Over Temperature, Short Circuit), and 8-SOIC package type.

Q: Does the MAX5024MASA+ maintain the same regulatory compliance as the original part?

A: Yes. The MAX5024MASA+ is ROHS3 compliant and REACH unaffected, matching the compliance status of the MAX5024MASA. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions.
