Parameter Comparison

Engineering Selection Recommendations

Both the AP7353-31CV4-7 and AP7353D-31CV4-7 are active production components manufactured by Diodes Incorporated with identical electrical specifications and mechanical packaging. Selection between these parts is based on the following factors:

Availability and Inventory: The AP7353D-31CV4-7 has higher inventory availability (3804 pieces) compared to the AP7353-31CV4-7 (1093 pieces). For applications requiring immediate procurement or high-volume orders, the AP7353D-31CV4-7 provides greater supply assurance.

Compliance and Qualification: Both parts are ROHS3 compliant and carry AEC-Q100 automotive qualification. The AP7353-31CV4-7 explicitly lists automotive series designation, while the AP7353D-31CV4-7 includes automotive grade and AEC-Q100 qualification. Both are suitable for automotive applications within the specified operating temperature range of -40°C to 85°C.

Electrical Performance: The AP7353D-31CV4-7 exhibits marginally lower dropout voltage (0.142V versus 0.147V at 250mA), representing a 3.4% improvement in efficiency. All other electrical parameters are identical.

Regulatory Status: Both parts are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the AP7353D-31CV4-7 be used as a direct replacement for the AP7353-31CV4-7?

A: Yes. The AP7353D-31CV4-7 is a parametric equivalent substitute with identical electrical specifications, output voltage, current rating, operating temperature range, package type, and mounting configuration. Both parts are manufactured by Diodes Incorporated and carry the same compliance certifications.

Q: What is the difference between the AP7353-31CV4-7 and AP7353D-31CV4-7?

A: The primary differences are inventory availability and dropout voltage specification. The AP7353D-31CV4-7 has higher stock levels (3804 vs. 1093 pieces) and a slightly lower maximum dropout voltage (0.142V versus 0.147V at 250mA). All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the AP7353-31CV4-7 and AP7353D-31CV4-7 carry AEC-Q100 qualification and are rated for automotive use. Both operate across the temperature range of -40°C to 85°C and comply with ROHS3 and REACH requirements.

Q: What is the package type for these regulators?

A: Both parts use the 4-XFBGA (4-pin Extreme Flip Chip Ball Grid Array) package in the WLBGA form factor, with the supplier device package designation X1-WLB0707-4 (Type A1). This is a surface mount package with MSL rating of 1 (Unlimited moisture sensitivity).

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts have identical mechanical packaging, pin configuration, and mounting type (surface mount). PCB layouts designed for the AP7353-31CV4-7 are directly compatible with the AP7353D-31CV4-7 without modification.

Q: What are the key electrical specifications for component selection?

A: The critical specifications are: fixed 3.1V output voltage, 5.5V maximum input voltage, 250mA output current, 27µA quiescent current, and 0.147V (AP7353-31CV4-7) or 0.142V (AP7353D-31CV4-7) maximum dropout voltage at full load. Both include current limit, enable control, and over-current, over-temperature, and short-circuit protection.

Q: What is the PSRR specification and why is it important?

A: Power Supply Rejection Ratio (PSRR) is specified as 90dB at 100Hz declining to 70dB at 10kHz for both parts. PSRR indicates the regulator's ability to reject input voltage ripple and noise, which is critical for maintaining clean output voltage in noise-sensitive applications.

Q: Are there any moisture handling considerations for these components?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations. These components can be stored and handled without special moisture control measures, simplifying supply chain and manufacturing processes.
