Substitute Part Grouping Explanation

The AP7370-28WR-7 qualifies as a parametric equivalent to the AP7370-28WW-7 based on the following substitution criteria:

Electrical Equivalence:

• Identical output voltage: 2.8V fixed
• Identical maximum input voltage: 18V
• Identical output current rating: 300mA
• Identical quiescent current: 2.5 µA
• Identical protection feature set: Over Current, Over Temperature, Reverse Current, Short Circuit
• Identical operating temperature range: -40°C ~ 125°C

Mechanical & Packaging Equivalence:

• Identical package designation: SC-74A, SOT-753
• Identical mounting type: Surface Mount
• Identical supplier device package: SOT-25

Compliance & Certification Equivalence:

• Identical RoHS status: ROHS3 Compliant
• Identical MSL rating: Level 1 (Unlimited)
• Identical REACH status: REACH Unaffected

The substitution is based solely on matching all provided electrical, mechanical, and compliance parameters. Both parts share the same base product number (AP7370) and differ only in tape reel configuration designation.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7370-28WW-7 and AP7370-28WR-7 maintain Active product status with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts is determined by inventory availability and tape reel configuration requirements rather than functional or electrical differences.

The AP7370-28WW-7 currently maintains 918 pieces in stock inventory, while the AP7370-28WR-7 maintains 815 pieces. Both parts carry identical MSL Level 1 rating, eliminating moisture sensitivity constraints for storage and handling.

Component selection should prioritize availability and supply chain logistics. No electrical, thermal, or mechanical re-qualification is required when substituting between these parts in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can AP7370-28WR-7 replace AP7370-28WW-7 in production designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (2.8V fixed), output current (300mA), input voltage tolerance (18V maximum), operating temperature range (-40°C to 125°C), and package designation (SC-74A, SOT-753). No circuit redesign or re-qualification is required.

Q: What is the difference between AP7370-28WW-7 and AP7370-28WR-7?

A: The parts differ only in tape reel configuration designation (WW versus WR suffix). All electrical, mechanical, and compliance parameters are identical. The difference reflects packaging and supply chain handling specifications only.

Q: Are both parts RoHS compliant?

A: Yes. Both AP7370-28WW-7 and AP7370-28WR-7 are ROHS3 Compliant with MSL Level 1 rating and REACH Unaffected status.

Q: What protection features are included in these regulators?

A: Both parts include Over Current, Over Temperature, Reverse Current, and Short Circuit protection features.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical Surface Mount packaging (SC-74A, SOT-753) and SOT-25 supplier device package designation, enabling direct PCB footprint compatibility without layout modifications.
