Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7353-18CV4-7 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (1.8V fixed)
• Maximum output current rating (250mA)
• Input voltage range (5.5V maximum)
• Dropout voltage performance (0.237V @ 250mA)
• Package type (4-XFBGA, WLBGA)
• Control and protection feature set (Enable control, Over Current, Over Temperature, Short Circuit protection)
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (RoHS3, REACH unaffected)

The AP7353D-18CV4-7 meets all substitution criteria as a parametric equivalent within the AP7353 product family.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7353-18CV4-7 and AP7353D-18CV4-7 are Active products with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The identical MSL rating of 3 (168 Hours) applies to both variants, requiring equivalent moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can AP7353D-18CV4-7 be used as a direct replacement for AP7353-18CV4-7?
