Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7370-15WW-7 are identified as parametric equivalents within the AP7370 base product family. Substitution is valid when all critical electrical parameters match exactly: output voltage (1.5V fixed), maximum output current (300mA), maximum input voltage (18V), quiescent current (2.5 µA), operating temperature range (-40°C to 125°C), and package type (SOT-25/SC-74A). All substitute parts share identical protection features (Over Current, Over Temperature, Reverse Current, Short Circuit), compliance certifications (ROHS3, REACH Unaffected), and moisture sensitivity ratings (MSL 1). The substitutes differ only in packaging designation suffix, which reflects manufacturing tape and reel configurations but does not affect electrical performance or pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AP7370-15WW-7, AP7370-15W5-7, and AP7370-15WR-7—are Active status products from Diodes Incorporated with identical electrical specifications and compliance certifications. Selection among these equivalents is determined by packaging and inventory availability. The AP7370-15WW-7 maintains 1037 units in stock, the AP7370-15W5-7 has 1057 units available, and the AP7370-15WR-7 has 904 units in inventory. All parts meet ROHS3 compliance and REACH Unaffected status, making them suitable for applications requiring environmental regulatory adherence. The choice between these substitutes does not affect circuit performance, thermal characteristics, or protection functionality.

Frequently Asked Questions (FAQ)

Q: Can AP7370-15W5-7 and AP7370-15WR-7 be used interchangeably with AP7370-15WW-7? A: Yes. All three parts are parametric equivalents with identical electrical specifications, output voltage (1.5V), output current (300mA), input voltage range (18V max), operating temperature (-40°C to 125°C), and SOT-25 package configuration. The suffix variation reflects only tape and reel packaging designations.

Q: Are there any pinout differences between these substitute parts? A: No. All three parts use the SC-74A/SOT-753 package with identical pinout. Direct PCB substitution is possible without circuit modification.

Q: Do all substitute parts have the same protection features? A: Yes. Over Current, Over Temperature, Reverse Current, and Short Circuit protection are present in AP7370-15WW-7, AP7370-15W5-7, and AP7370-15WR-7.

Q: What is the significance of the packaging suffix (WW, W5, WR)? A: The suffix designates the tape and reel configuration for automated assembly. Electrical performance and functionality remain identical across all variants.

Q: Are compliance certifications identical across all three parts? A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected based on availability? A: Selection should be based on current inventory levels and supply chain requirements. AP7370-15W5-7 has the highest inventory (1057 units), followed by AP7370-15WW-7 (1037 units) and AP7370-15WR-7 (904 units).
