Key Parameters

Substitute Part Grouping Explanation

Substitution within the AP130 series is determined by electrical parameter equivalence across output voltage, output current, input voltage range, dropout voltage, quiescent current, and thermal protection characteristics. All three part numbers—AP130-33SAG-7, AP130-33RG-7, and AP130-33WG-7—maintain identical electrical specifications and operating performance. Differentiation occurs only in supplier device packaging designation (SOT-23-3, SC-59R, and SC-59-3 respectively) and moisture sensitivity level (MSL) rating. These packaging variants represent different manufacturing and handling specifications from Diodes Incorporated while preserving core functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are Active status products from Diodes Incorporated with ROHS3 compliance and REACH unaffected designation. Selection between AP130-33SAG-7, AP130-33RG-7, and AP130-33WG-7 is determined by packaging requirements and moisture sensitivity constraints applicable to the assembly and storage environment. AP130-33SAG-7 with MSL 1 rating is suitable for applications with unlimited shelf life and minimal moisture control requirements. AP130-33RG-7 and AP130-33WG-7, both rated MSL 3 (168 Hours), require controlled storage conditions and are appropriate for high-volume manufacturing environments with established moisture management protocols. Electrical performance and thermal protection characteristics remain constant across all three variants.

Frequently Asked Questions (FAQ)

Q: Are AP130-33SAG-7, AP130-33RG-7, and AP130-33WG-7 electrically interchangeable?

A: Yes. All three part numbers deliver identical electrical performance: 3.3V fixed output, 300mA output current, 0.5V maximum dropout voltage at 300mA, 100 µA quiescent current, and equivalent protection features. Substitution is electrically valid across all three variants.

Q: What is the difference between the three part numbers?

A: The primary differences are supplier device package designation and moisture sensitivity level. AP130-33SAG-7 uses SOT-23-3 packaging with MSL 1 (unlimited shelf life). AP130-33RG-7 uses SC-59R packaging with MSL 3 (168 hours). AP130-33WG-7 uses SC-59-3 packaging with MSL 3 (168 hours). All three are Surface Mount devices with identical electrical specifications.

Q: Which part should I select for long-term storage without moisture control?

A: AP130-33SAG-7 with MSL 1 rating is appropriate for applications requiring unlimited shelf life without active moisture management. Parts with MSL 3 rating require controlled storage conditions and have a 168-hour moisture exposure limit.

Q: Are there any compliance or certification differences between these parts?

A: No. All three part numbers are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Can I substitute these parts on an existing PCB design?

A: Substitution is valid only if the PCB footprint accommodates the target package type. SOT-23-3, SC-59R, and SC-59-3 are distinct package configurations. Verify footprint compatibility before substitution.
