UCC24630DBVT Equivalent & Substitute Parts

Part Overview

The UCC24630DBVT is an active, production-status secondary-side power supply controller manufactured by Texas Instruments in SOT-23-6 surface mount packaging. This integrated circuit functions as a flyback regulator controller for isolated power management applications. Secondary-side controllers are essential components in isolated power supply designs where feedback and regulation occur on the isolated output side of the transformer. Alternative models may be required due to inventory constraints, application-specific packaging needs, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The AP3108LGSTR-G1 is identified as a manufacturer-recommended substitute for the UCC24630DBVT based on functional equivalence as a secondary-side power supply controller. Both devices operate within overlapping supply voltage ranges and are designed for isolated power management applications. Substitution eligibility is determined by the following key parameters:

• Functional classification: Secondary-side controller
• Product status: Active production status
• Supply voltage compatibility: Overlapping operational ranges
• Regulatory compliance: ROHS3 and REACH compliance alignment
• Surface mount technology: Both devices use surface mount construction

The primary distinction between these parts is packaging format: the UCC24630DBVT uses SOT-23-6 (6-lead), while the AP3108LGSTR-G1 uses 9-SSOP (9-lead). This packaging difference requires PCB layout and schematic modifications during substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the UCC24630DBVT and AP3108LGSTR-G1 maintain active production status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on the following factors:

The UCC24630DBVT operates across a lower supply voltage floor (3.6V minimum) compared to the AP3108LGSTR-G1 (10V minimum), making the UCC24630DBVT suitable for applications requiring operation at lower supply voltages. The UCC24630DBVT also features a lower supply current specification (900 µA versus 1.7 mA) and an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C).

The AP3108LGSTR-G1 offers higher inventory availability (30,300 pieces versus 1,550 pieces) and features a lower moisture sensitivity level classification (MSL 3 versus MSL 1), which may reduce handling and storage requirements in certain manufacturing environments.

Packaging format differences require design modification: the SOT-23-6 package of the UCC24630DBVT differs from the 9-SSOP package of the AP3108LGSTR-G1, necessitating PCB layout changes and schematic pin reassignment during substitution.

Frequently Asked Questions (FAQ)

Q: Can the AP3108LGSTR-G1 directly replace the UCC24630DBVT without PCB modifications?

A: No. The AP3108LGSTR-G1 uses a 9-SSOP package while the UCC24630DBVT uses SOT-23-6 packaging. These packages have different pin counts, pin spacing, and physical dimensions. PCB layout redesign and schematic pin mapping are required.

Q: What is the minimum supply voltage difference between these parts?

A: The UCC24630DBVT operates from 3.6V minimum supply voltage, while the AP3108LGSTR-G1 requires a 10V minimum. Applications operating below 10V supply voltage cannot use the AP3108LGSTR-G1 as a substitute.

Q: Are both parts suitable for high-temperature applications?

A: The UCC24630DBVT supports operation to 125°C, while the AP3108LGSTR-G1 is rated to 85°C maximum. For applications requiring operation above 85°C, the UCC24630DBVT is the appropriate selection.

Q: What does MSL rating mean for component handling?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions before soldering. The UCC24630DBVT (MSL 1) has unlimited shelf life under standard conditions, while the AP3108LGSTR-G1 (MSL 3) must be soldered within 168 hours of package opening.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the UCC24630DBVT and AP3108LGSTR-G1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Which part has lower power consumption?

A: The UCC24630DBVT draws 900 µA supply current, compared to 1.7 mA for the AP3108LGSTR-G1. The UCC24630DBVT is the lower-power option.
