Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ring generator controller ICs is determined by functional equivalence in the following parameters:

• Primary Function: Ring Generator Controller capability
• Supply Voltage Compatibility: Operating voltage range must accommodate system requirements
• Current Supply Rating: Must meet or exceed 500µA specification
• Surface Mount Compatibility: Package must support surface mount assembly processes
• Thermal Operating Range: Must cover required operational temperature envelope
• Compliance & Certification: ECCN and HTSUS classifications for regulatory alignment

The UCC3750DW is identified as a manufacturer-recommended substitute based on shared ring generator controller functionality and compatible electrical characteristics within the telecom interface category.

Parameter Comparison

Engineering Selection Recommendations

The UCC3750DW is an active product substitute for the obsolete UCC3752D. Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring regulatory alignment for export and tariff purposes.

Key considerations for component selection:

• Supply Voltage Differential: The UCC3750DW operates at 5V versus the UCC3752D's 12V supply requirement. System power architecture must accommodate this voltage difference.
• Operating Temperature Range: The UCC3752D supports -40°C ~ 125°C operation, while the UCC3750DW is rated 0°C ~ 70°C. Applications requiring extended temperature performance must evaluate thermal requirements against the substitute's narrower range.
• Package Footprint: The UCC3750DW uses a 28-SOIC package (7.50mm width) compared to the UCC3752D's 16-SOIC package (3.90mm width). PCB layout modifications are required for package accommodation.
• Current Supply: Both components maintain 500µA current supply specification, ensuring equivalent power consumption characteristics.
• Product Status: The UCC3750DW's Active status provides ongoing availability and supply chain continuity compared to the Obsolete UCC3752D.

Frequently Asked Questions (FAQ)

Q: Can the UCC3750DW directly replace the UCC3752D without circuit modifications?

A: Direct pin-for-pin replacement is not possible due to package differences (16-SOIC versus 28-SOIC). Additionally, the supply voltage requirement differs (5V versus 12V), necessitating power supply circuit evaluation and potential redesign.

Q: What is the primary reason for substitution?

A: The UCC3752D is classified as Obsolete. The UCC3750DW is an Active product offering equivalent ring generator controller functionality with ongoing manufacturer support and supply availability.

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

A: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. No regulatory compliance divergence exists between the two parts.

Q: How do the operating temperature ranges compare?

A: The UCC3752D operates across -40°C ~ 125°C, while the UCC3750DW is rated 0°C ~ 70°C. Applications requiring extended low-temperature or high-temperature operation must verify the UCC3750DW's thermal suitability.

Q: What package considerations apply to substitution?

A: The UCC3750DW's 28-SOIC package is larger than the UCC3752D's 16-SOIC package. PCB layout redesign is required to accommodate the increased footprint and pin count.

Q: Is the current supply specification equivalent?

A: Yes, both components maintain 500µA current supply rating, ensuring equivalent power consumption in ring generator controller applications.
