UCC3583N Equivalent & Substitute Parts

Part Overview

The UCC3583N is a secondary-side controller IC designed for power supply applications, manufactured by Texas Instruments in a 14-PDIP through-hole package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replacement in existing systems. The UCC3583N operates within a supply voltage range of 8.9V to 14V with a supply current of 3 mA and supports operating temperatures from 0°C to 70°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC3583N is determined by the following critical parameters:

• Base Product Number: UCC3583 (functional equivalence)
• Voltage - Supply: 8.9V ~ 14V (must match exactly)
• Current - Supply: 3 mA (must match exactly)
• Operating Temperature Range: 0°C ~ 70°C (must match exactly)
• Functional Application: Secondary-Side Controller (must match)

The UCC3583D qualifies as a manufacturer-recommended substitute because it shares the identical base product number (UCC3583), maintains the same electrical specifications (supply voltage, current, and temperature range), and performs the same secondary-side controller function. The primary difference is the package format: UCC3583D uses a 14-SOIC surface-mount package instead of the through-hole 14-DIP package of the UCC3583N.

Parameter Comparison

Engineering Selection Recommendations

The UCC3583D is the manufacturer-recommended substitute for the obsolete UCC3583N. Both components share identical electrical specifications and functional performance as secondary-side power supply controllers. The UCC3583D carries an Active product status, ensuring continued availability and support compared to the Obsolete status of the UCC3583N.

Selection between these parts depends on board design constraints:

• UCC3583N (14-DIP): Suitable for through-hole PCB designs or applications requiring through-hole mounting compatibility.
• UCC3583D (14-SOIC): Suitable for surface-mount PCB designs, offering reduced board space and modern manufacturing compatibility.

Both components comply with ROHS3 and maintain identical export classification (EAR99) and tariff codes (HTSUS 8542.39.0001). The electrical performance, supply voltage range (8.9V ~ 14V), supply current (3 mA), and operating temperature range (0°C ~ 70°C) are identical, ensuring functional interchangeability within the constraints of the respective package types and mounting technologies.

Frequently Asked Questions (FAQ)

Q: Can the UCC3583D directly replace the UCC3583N on an existing PCB?

A: Direct PCB replacement is not possible without redesign. The UCC3583N uses through-hole mounting (14-DIP package), while the UCC3583D uses surface-mount technology (14-SOIC package). PCB layout and footprint modifications are required for substitution.

Q: Are the electrical specifications identical between UCC3583N and UCC3583D?

A: Yes. Both components operate within the same supply voltage range (8.9V ~ 14V), draw the same supply current (3 mA), and support the same operating temperature range (0°C ~ 70°C). They perform identical secondary-side controller functions.

Q: Why is the UCC3583N listed as Obsolete?

A: The UCC3583N is obsolete due to market transition toward surface-mount technology. The UCC3583D (14-SOIC) represents the active equivalent in the UCC3583 product family.

Q: What is the significance of the Base Product Number (UCC3583)?

A: The base product number indicates the core functional design. Both UCC3583N and UCC3583D share the same base product number, confirming they are variants of the same controller architecture with different package options.

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

A: Both components carry identical compliance designations: ROHS3 Compliant, EAR99 export classification, and HTSUS code 8542.39.0001. No compliance differences exist between the two parts.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: The UCC3583N carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
