IR11672ASPBF Equivalent & Substitute Parts

Part Overview

The IR11672ASPBF is a Power Management IC (PMIC) manufactured by Infineon Technologies, functioning as a secondary-side controller for power supply applications. This 8-SOIC packaged device operates with an input voltage of 200V and a supply voltage range of 11.4V to 18V, delivering 50 mA supply current. The device is part of the Advanced Smart Rectifier™ series and is classified as discontinued at DiGi Electronics. Due to its discontinued status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the IR11672ASPBF is determined by functional equivalence within the secondary-side controller category and compatibility across the following critical parameters:

Primary Substitution Criteria:

• Functional classification: Secondary-side power supply controller
• Package type: Surface mount, 8-pin configuration
• Supply voltage compatibility: Operating range must accommodate 11.4V ~ 18V or equivalent input specifications
• Current handling capability: Minimum 50 mA supply current requirement
• Temperature rating: Operating range of -25°C to 125°C or broader
• Compliance standards: ROHS3 compliance and equivalent regulatory certifications

The UCC24610DRBR from Texas Instruments qualifies as a functional equivalent based on its secondary-side controller architecture, surface mount 8-pin package (8-SON), and active product status with higher inventory availability.

Engineering Selection Recommendations

The UCC24610DRBR is an active substitute for the discontinued IR11672ASPBF based on the following engineering factors:

Product Status: The IR11672ASPBF is discontinued at DiGi Electronics, whereas the UCC24610DRBR maintains active product status with significantly higher inventory availability (23,100 units versus 5,044 units).

Compliance & Certifications: Both devices maintain ROHS3 compliance, identical MSL ratings (2, 1 Year), and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001), ensuring regulatory continuity.

Functional Equivalence: Both devices operate as secondary-side controllers within power supply architectures, with compatible surface mount configurations and thermal operating ranges that overlap at the critical -25°C to 125°C specification window.

Package Consideration: The IR11672ASPBF uses 8-SOIC packaging while the UCC24610DRBR uses 8-SON packaging. Both are 8-pin surface mount configurations with similar footprint dimensions, though PCB layout modifications may be required due to different pin pitch and body dimensions.

Frequently Asked Questions (FAQ)

Q: Can the UCC24610DRBR directly replace the IR11672ASPBF without circuit modifications?

A: Both devices function as secondary-side controllers with compatible thermal and compliance specifications. However, the package transition from 8-SOIC to 8-SON requires PCB footprint redesign. Pin-to-pin functional compatibility must be verified against the specific application schematic and datasheet pin assignments.

Q: What is the primary reason for substitution?

A: The IR11672ASPBF is discontinued at DiGi Electronics. The UCC24610DRBR provides functional equivalence as an active product with higher inventory availability, ensuring design continuity and supply chain reliability.

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

A: No. Both devices maintain identical ROHS3 compliance status, MSL ratings, and regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001), ensuring no regulatory impact from substitution.

Q: How do the supply voltage specifications compare?

A: The IR11672ASPBF specifies 11.4V ~ 18V supply voltage, while the UCC24610DRBR specifies 4.5V ~ 5.5V input voltage. These represent different circuit topologies and application contexts. Voltage compatibility must be verified against your specific power supply design.

Q: What packaging considerations apply to this substitution?

A: The IR11672ASPBF uses 8-SOIC (0.154", 3.90mm width) packaging, while the UCC24610DRBR uses 8-SON (3x3) packaging. Both are surface mount 8-pin devices, but different body dimensions and pin pitch require PCB layout modifications. Consult manufacturer datasheets for precise footprint specifications.

Q: Is the operating temperature range compatible?

A: Yes. The IR11672ASPBF operates from -25°C to 125°C, while the UCC24610DRBR operates from -40°C to 125°C. The UCC24610DRBR provides an extended lower temperature range, ensuring compatibility across the original device's thermal specification window.
