Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM2103M is determined by the following critical parameters:

Functional Compatibility Criteria:

• Category classification as Power Management (PMIC)
• Application domain: Power Supply Controller functionality
• Input voltage range compatibility
• Supply voltage operating range
• Current consumption specifications
• Operating temperature range
• Surface mount capability

Package Compatibility Considerations:

• Surface mount technology requirement
• Pin count and electrical interface equivalence
• Physical footprint accommodation in existing designs

The UCC24610DRBR qualifies as a substitute based on shared Power Management (PMIC) category classification, surface mount technology, and compatible operating temperature range. Both devices function as power supply controllers within the specified voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The NJM2103M is classified as Obsolete. The UCC24610DRBR is classified as Active, ensuring ongoing availability, manufacturing support, and supply chain continuity.

Compliance and Certification: The UCC24610DRBR carries the following certifications and compliance designations:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level (MSL): 2 (1 Year)
• ECCN: EAR99

The NJM2103M carries ECCN designation as Obsolete with no current compliance documentation.

Operational Temperature Range: The UCC24610DRBR provides an extended operating temperature range (-40°C ~ 125°C) compared to the NJM2103M (-40°C ~ 85°C), offering broader thermal performance capability.

Supply Chain Availability: Current inventory for UCC24610DRBR is 23,100 pieces, compared to 7,013 pieces for the NJM2103M. Active product status ensures continued availability for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the UCC24610DRBR directly replace the NJM2103M in existing designs?

A: Both devices are Power Management (PMIC) controllers with surface mount technology. However, package differences exist: the NJM2103M uses 8-SOIC (0.197", 5.00mm Width) while the UCC24610DRBR uses 8-VDFN Exposed Pad. PCB layout modifications are required to accommodate the different package footprint.

Q: What are the voltage parameter differences between these parts?

A: The NJM2103M operates with input voltage 4.1V ~ 4.4V and supply voltage 0.8V ~ 20V. The UCC24610DRBR operates with input voltage 4.5V ~ 5.5V. Supply voltage specification for the UCC24610DRBR is not provided in the available documentation. Application-specific voltage requirements must be evaluated against these ranges.

Q: How do the current consumption specifications compare?

A: The NJM2103M draws 460 µA supply current, while the UCC24610DRBR draws 2.15 mA. The UCC24610DRBR exhibits higher current consumption. Power budget calculations for the target application must account for this difference.

Q: What is the significance of the different operating temperature ranges?

A: The NJM2103M operates from -40°C to 85°C. The UCC24610DRBR operates from -40°C to 125°C. Applications requiring operation above 85°C benefit from the extended upper temperature limit of the UCC24610DRBR.

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

A: The UCC24610DRBR is RoHS3 Compliant and REACH Unaffected with defined Moisture Sensitivity Level (MSL) 2. The NJM2103M is Obsolete with no current compliance documentation. New designs should prioritize the UCC24610DRBR for regulatory compliance assurance.

Q: What application domains does each part serve?

A: The NJM2103M is specified for Power Supply and Supervisor applications. The UCC24610DRBR is specified for Flyback, Forward Converters, and LLC converter topologies. Application topology compatibility must be verified for the target design.
