Key Parameters

Substitute Part Grouping Explanation

The AP7333-12SRG-7 qualifies as a parametric equivalent to the AP7333-12SAG-7 based on the following substitution criteria:

Electrical Parameters (Identical):

• Output voltage: 1.2V fixed
• Maximum output current: 300mA
• Maximum input voltage: 6V
• Quiescent current: 75 µA
• Supply current (max): 85 µA
• PSRR: 65dB (100Hz)
• Protection features: Over Current, Over Temperature, Short Circuit
• Operating temperature range: -40°C ~ 85°C

Mechanical & Compliance Parameters (Identical):

• Manufacturer: Diodes Incorporated
• Base product number: AP7333
• Mounting type: Surface Mount
• Package designation: TO-236-3, SC-59, SOT-23-3
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

Packaging Variation: The primary distinction is the supplier device package designation: SAG-7 uses SOT-23-3 tape & reel packaging, while SRG-7 uses SOT23R tape & reel packaging. Both packages are mechanically and electrically compatible within the TO-236-3/SC-59/SOT-23-3 family.

Parameter Comparison

Engineering Selection Recommendations

Both AP7333-12SAG-7 and AP7333-12SRG-7 are Active status products from Diodes Incorporated with identical electrical specifications and full compliance certifications (ROHS3, REACH Unaffected). Selection between these parts is determined by packaging availability and supply chain requirements rather than functional differences. The AP7333-12SRG-7 offers higher inventory availability (30,100 pcs vs. 3,951 pcs) while maintaining equivalent performance characteristics. Both parts satisfy identical design requirements for 1.2V, 300mA linear voltage regulation applications with comprehensive protection features across the -40°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Are AP7333-12SAG-7 and AP7333-12SRG-7 pin-compatible? A: Yes. Both parts use the TO-236-3/SC-59/SOT-23-3 package family with identical pinout and electrical characteristics. The difference in supplier device package designation (SOT-23-3 vs. SOT23R) reflects tape & reel packaging variations that do not affect circuit board assembly or functionality.

Q: Can I substitute AP7333-12SRG-7 for AP7333-12SAG-7 in existing designs? A: Yes. The parts are electrically and mechanically equivalent. No design changes are required. Both deliver identical 1.2V fixed output at 300mA with the same protection features and operating temperature range.

Q: What are the key parameters that define substitution eligibility? A: Substitution is based on matching output voltage (1.2V), output current (300mA), input voltage rating (6V max), quiescent current (75 µA), protection features (Over Current, Over Temperature, Short Circuit), operating temperature range (-40°C ~ 85°C), package type (SOT-23-3), and compliance certifications (ROHS3, REACH Unaffected).

Q: Do both parts have the same moisture sensitivity level? A: Yes. Both AP7333-12SAG-7 and AP7333-12SRG-7 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance differences between these parts? A: No. Both parts are ROHS3 Compliant and REACH Unaffected with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
