Substitute Part Grouping Explanation

The AP7361C-10ER-13 qualifies as a parametric equivalent to the AP7361C-10E-13 based on the following substitution criteria:

Electrical Performance Match:

Identical output voltage: 1V fixed
Identical maximum input voltage: 6V
Identical output current rating: 1A
Identical dropout voltage: 0.84V @ 1A (Typ)
Identical quiescent current: 80 µA
Identical PSRR specification: 75dB ~ 55dB (1kHz ~ 10kHz)

Thermal & Protection Match:

Identical operating temperature range: -40°C ~ 85°C
Identical protection features: Over Current, Over Temperature

Compliance & Status Match:

Same manufacturer: Diodes Incorporated
Same product status: Active
Same RoHS compliance: ROHS3 Compliant
Same MSL rating: 1 (Unlimited)

Packaging Difference: The primary distinction is the supplier device package: SOT-223-3 (main part) versus SOT-223R (substitute part). Both are Surface Mount configurations within the TO-261 family, representing different tape & reel packaging formats from the same manufacturer.

Engineering Selection Recommendations

Both the AP7361C-10E-13 and AP7361C-10ER-13 are Active products from Diodes Incorporated with full ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The AP7361C-10E-13 with SOT-223-3 packaging and the AP7361C-10ER-13 with SOT-223R packaging deliver equivalent circuit performance in 1V/1A linear regulation applications. The choice between them depends on PCB assembly equipment compatibility, tape & reel format specifications, and component availability from your supply chain.

Both parts maintain identical thermal performance across the -40°C to 85°C operating range and provide equivalent protection against overcurrent and overtemperature conditions. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are identical across both variants.

Frequently Asked Questions (FAQ)

Q: Can AP7361C-10ER-13 replace AP7361C-10E-13 in existing designs?

A: Yes. The electrical specifications, output voltage, current rating, dropout voltage, quiescent current, and thermal characteristics are identical. The difference is limited to the supplier device package format (SOT-223-3 versus SOT-223R). PCB layout and assembly equipment must accommodate the specific package variant selected.

Q: What is the difference between SOT-223-3 and SOT-223R packaging?

A: Both are Surface Mount packages within the TO-261 family supplied on tape & reel. SOT-223-3 and SOT-223R represent different tape & reel configurations from Diodes Incorporated. Verify your assembly equipment specifications and PCB footprint requirements before selecting between these variants.

Q: Are both parts currently available?

A: Both parts maintain Active product status. The AP7361C-10E-13 has 725 pcs in stock, while the AP7361C-10ER-13 has 3093 pcs in stock. Availability may vary by distributor and time of order.

Q: Do these parts have identical compliance certifications?

A: Yes. Both the AP7361C-10E-13 and AP7361C-10ER-13 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. MSL rating is 1 (Unlimited) for both variants.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on matching output voltage (1V fixed), maximum input voltage (6V), output current (1A), dropout voltage (0.84V @ 1A Typ), quiescent current (80 µA), PSRR (75dB ~ 55dB), operating temperature range (-40°C ~ 85°C), and protection features (Over Current, Over Temperature).
