Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP2UC-101-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 100 µH (fixed requirement)
• Inductance tolerance: ±20% (acceptable range)
• Shielding configuration: Unshielded (electromagnetic environment compatibility)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

Secondary Compatibility Criteria:

• Current rating: Minimum 1.0 A (circuit load capacity)
• DC resistance: Maximum 380mOhm (power dissipation and thermal performance)
• Operating temperature range: Minimum -25°C to 85°C overlap (thermal environment)
• Saturation current (Isat): Minimum 1.2 A (magnetic core stability)

All substitute parts listed meet the primary matching criteria. Variations in secondary parameters are documented to enable application-specific selection based on circuit requirements.

Engineering Selection Recommendations

UP2UC-101-R (Eaton - Electronics Division) Primary selection for applications requiring the specified -25°C to 85°C operating range. RoHS Compliant status. Inventory availability: 11,911 pcs. Suitable for standard industrial and consumer electronics applications within the defined thermal envelope.

P0752.104NLT (Pulse Electronics) Direct substitute with extended operating temperature range (-40°C to 130°C). ROHS3 Compliant. Current rating of 1.2 A is acceptable for circuits designed for 1.3 A maximum. DC resistance of 380mOhm represents increased power dissipation compared to the main part. Inventory availability: 3,163 pcs. Suitable for applications requiring extended temperature performance or where higher ambient temperatures are encountered.

SDR1005-101KL (Bourns Inc.) Substitute with tighter inductance tolerance (±10% versus ±20%), ferrite drum core construction, and extended operating temperature range (-40°C to 125°C). ROHS3 Compliant. Current rating of 1.0 A is the lowest among all options; selection requires verification that circuit peak current does not exceed this rating. DC resistance of 330mOhm. Inventory availability: 3,418 pcs. Suitable for precision applications where inductance tolerance is critical and thermal performance extends to -40°C.

B82476A1104M000 (EPCOS - TDK Electronics) Substitute with lowest DC resistance (230mOhm), matching the 1.3 A current rating of the main part. Ferrite drum core construction. Extended operating temperature range (-55°C to 150°C) provides maximum thermal margin. ROHS3 Compliant. Inventory availability: 6,551 pcs. Optimal selection for applications prioritizing low power dissipation, high-temperature operation, or where thermal performance is a design constraint.

All substitute parts maintain Active product status and comply with RoHS requirements. Selection should be based on specific circuit requirements for current rating, DC resistance, operating temperature range, and inductance tolerance.

Frequently Asked Questions (FAQ)

Q: Can P0752.104NLT replace UP2UC-101-R in all applications?

A: P0752.104NLT is a functional substitute for applications where the 1.2 A current rating is sufficient and the higher DC resistance of 380mOhm does not exceed thermal dissipation limits. The extended operating temperature range (-40°C to 130°C) provides additional margin beyond the main part's -25°C to 85°C range. Verify circuit current requirements before substitution.

Q: What is the significance of the ±10% tolerance in SDR1005-101KL compared to ±20% in other parts?

A: The ±10% inductance tolerance in SDR1005-101KL provides tighter inductance value control, suitable for applications where inductance accuracy directly affects circuit performance (such as resonant frequency-dependent circuits). The main part UP2UC-101-R and most substitutes specify ±20% tolerance, which is acceptable for general-purpose filtering and energy storage applications.

Q: Is the ferrite core construction in SDR1005-101KL and B82476A1104M000 compatible with UP2UC-101-R applications?

A: Both ferrite core substitutes are unshielded wirewound inductors matching the main part's shielding configuration. Ferrite core construction does not introduce electromagnetic compatibility issues in unshielded applications. However, ferrite cores exhibit different frequency response characteristics. Verify that the inductance frequency test conditions (1 kHz for SDR1005-101KL versus 100 kHz for UP2UC-101-R and B82476A1104M000) align with circuit operating frequencies.

Q: Why does B82476A1104M000 have lower DC resistance than the main part?

A: B82476A1104M000 exhibits 230mOhm maximum DC resistance compared to 280mOhm in UP2UC-101-R, resulting in lower power dissipation and reduced thermal generation. This characteristic is advantageous in applications where inductor heating is a concern or where thermal management is constrained. The lower resistance does not affect functional substitution eligibility.

Q: Are there PCB layout considerations when substituting parts with different physical dimensions?

A: Physical dimensions vary between substitutes. UP2UC-101-R and SDR1005-101KL share identical footprint dimensions (0.500" L x 0.394" W). P0752.104NLT and B82476A1104M000 use larger footprints (0.510" L x 0.370" W). Height variations range from 0.197" to 0.215". Verify PCB layout clearances and component placement constraints before substitution. Footprint compatibility is required for direct board-level replacement without redesign.

Q: What is the impact of the 1.0 A current rating in SDR1005-101KL?

A: SDR1005-101KL is rated for 1.0 A continuous current, which is lower than the main part's 1.3 A rating. This part is suitable only for applications where circuit current remains below 1.0 A. Exceeding this rating risks inductor saturation and performance degradation. Verify maximum circuit current before selecting this substitute.

Q: Do all substitute parts meet the same compliance requirements as UP2UC-101-R?

A: All substitute parts are ROHS3 Compliant (enhanced RoHS compliance) or RoHS Compliant, meeting or exceeding the main part's RoHS Compliant status. All parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating identical handling and storage requirements. All parts are packaged in Tape & Reel (TR) format compatible with automated assembly processes.
