Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7315D-135FS4-7B are identified through parametric equivalence matching. The substitution criteria are based on the following key parameters that must remain constant:

• Fixed output voltage of 1.35V
• Output current rating of 150mA
• Maximum input voltage of 5.25V
• Voltage dropout specification of 0.64V @ 150mA
• Positive fixed output configuration
• 4-XDFN Exposed Pad package type (X2-DFN1010-4)
• Surface mount mounting type
• Operating temperature range of -40°C ~ 85°C
• Over current protection feature
• Active product status
• RoHS3 compliance

Parts meeting all these electrical and mechanical parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

The identical parametric specifications ensure direct functional interchangeability without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can AP7315-135FS4-7B be used as a direct replacement for AP7315D-135FS4-7B?

A: Yes. Both parts are parametric equivalents with identical output voltage (1.35V), output current (150mA), input voltage rating (5.25V), voltage dropout (0.64V @ 150mA), package type (4-XDFN Exposed Pad), and operating temperature range (-40°C ~ 85°C). Direct substitution is supported without circuit modification.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 4-XDFN Exposed Pad package (X2-DFN1010-4) with surface mount configuration. Pinout and PCB footprint compatibility is guaranteed.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AP7315D-135FS4-7B and AP7315-135FS4-7B are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What is the difference between the part numbers?

A: The part numbers differ only in the designator suffix (D vs. no suffix). Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. The difference does not affect functional performance or compatibility.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory levels and supplier availability. Both maintain Active product status with full technical support.
