Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1621EEE is determined by strict adherence to the following electrical and mechanical parameters:

• Package Compatibility: Both main and substitute parts must use 16-QSOP packaging with identical physical dimensions (16-SSOP, 0.154", 3.90mm Width) to ensure PCB footprint compatibility
• Electrical Specifications: Supply voltage range (3V ~ 5.5V), supply current (150µA), and operating temperature range (-40°C ~ 85°C) must be identical
• Functional Category: Both parts must be classified as Power Management (PMIC) devices with LCD Display bias supply functionality
• Base Product Number: Parts sharing the MAX1621 base product number are considered within the same functional family

The MAX1621EEE+ qualifies as a direct substitute based on these criteria, maintaining all specified electrical and mechanical parameters while differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX1621EEE+ serves as the direct substitute for MAX1621EEE applications. Both parts maintain identical electrical performance and package specifications required for LCD Display bias supply circuits.

For Existing Designs: The MAX1621EEE+ provides functional equivalence with improved compliance status. The transition from RoHS non-compliant to ROHS3 Compliant status represents an advancement in environmental and regulatory alignment. Both parts operate within identical supply voltage (3V ~ 5.5V), current (150µA), and temperature ranges (-40°C ~ 85°C).

For New Designs: The MAX1621EEE+ is classified as "Not For New Designs," indicating limited long-term availability. Designs requiring LCD Display PMIC functionality should evaluate alternative solutions from current product lines if extended production life is required.

Compliance Considerations: The MAX1621EEE+ achieves ROHS3 compliance and maintains REACH Unaffected status, supporting modern supply chain requirements. Both parts carry EAR99 export classification and identical HTSUS coding (8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can MAX1621EEE+ directly replace MAX1621EEE in existing circuits?

A: Yes. Both parts share identical electrical specifications (3V ~ 5.5V supply, 150µA current, -40°C ~ 85°C operating range) and package configuration (16-QSOP, 16-SSOP 0.154" width). No circuit modifications are required for direct substitution.

Q: What is the difference between MAX1621EEE and MAX1621EEE+?

A: The primary differences are product status and compliance certifications. MAX1621EEE is Obsolete and RoHS non-compliant, while MAX1621EEE+ is classified as Not For New Designs and achieves ROHS3 compliance. Electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: Both parts use 16-QSOP packaging with identical physical dimensions (16-SSOP, 0.154", 3.90mm Width). The MAX1621EEE+ is supplied in Tube packaging, while the main part packaging type is not specified. PCB footprint compatibility is maintained.

Q: Why is MAX1621EEE classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The MAX1621EEE+ (Not For New Designs) represents the final variant before complete discontinuation. For new LCD Display PMIC applications, evaluation of current-generation alternatives is recommended.

Q: What are the critical parameters for substitution?

A: Substitution eligibility requires matching supply voltage range (3V ~ 5.5V), supply current (150µA), operating temperature (-40°C ~ 85°C), package type (16-QSOP), and functional category (LCD Display PMIC). All parameters must align exactly for direct replacement.
