Packaging is provided in Tape & Reel (TR) format with active product status and substantial inventory availability (11,970 pcs).

P0751.103NLT (Pulse Electronics) serves as an alternative direct substitute meeting all primary electrical and mechanical criteria. This component provides a current rating of 3.8 A and maintains the required 10 µH inductance with ±20% tolerance. The DC resistance specification of 50mOhm is higher than the original 28.3mOhm; this parameter difference must be evaluated against application thermal and efficiency requirements. The operating temperature range of -40°C to 130°C encompasses the original specification. Packaging is available in Cut Tape (CT) & Digi-Reel® format with active product status and 8,411 pcs inventory.

B82476B1103M100 (EPCOS - TDK Electronics) is classified as a similar substitute with extended current capability. This component provides a higher current rating of 4.3 A while maintaining the 10 µH inductance and ±20% tolerance. The DC resistance of 27mOhm and operating temperature range of -55°C to 150°C provide performance margins beyond the original specification. This part carries AEC-Q200 qualification, indicating automotive-grade reliability. Use this substitute when higher current margin or automotive compliance is required. Packaging is Tape & Reel (TR) with active product status and 6,051 pcs inventory.

P0751.103NL (Pulse Electronics) is a packaging variant of P0751.103NLT with identical electrical specifications. This component is suitable for applications where Cut Tape packaging is not required. Inventory availability is 3,975 pcs.

SDR1005-100ML (Bourns Inc.) is classified as a similar substitute with reduced current rating. This component provides 2.9 A continuous current, which is lower than the original 3.61 A specification. Use this substitute only in applications where the actual operating current does not exceed 2.9 A. The component provides additional technical data including Q factor (43 @ 4MHz) and self-resonant frequency (26MHz). Packaging is Tape & Reel (TR) with active product status and 4,524 pcs inventory.

Frequently Asked Questions (FAQ)

Q: Can B82476A1103M000 be used as a direct replacement for UP2C-100-R without circuit modification?

A: Yes. The B82476A1103M000 meets all primary substitution criteria including inductance value (10 µH), tolerance (±20%), shielding (unshielded), mounting type (surface mount), and test frequency (100 kHz). The higher current rating (3.9 A vs. 3.61 A) and lower DC resistance (27mOhm vs. 28.3mOhm) provide improved performance margins. No circuit modification is required.

Q: What is the difference between P0751.103NLT and P0751.103NL?

A: These components are electrically identical with matching inductance, current rating, DC resistance, and operating temperature specifications. The primary difference is packaging format: P0751.103NLT is supplied in Cut Tape (CT) & Digi-Reel® format, while P0751.103NL packaging is not specified. Select based on your assembly equipment and supply chain requirements.

Q: Why does SDR1005-100ML have a lower current rating than the original UP2C-100-R?

A: The SDR1005-100ML is a different design variant from Bourns Inc. with a maximum continuous current rating of 2.9 A compared to the original 3.61 A. This component is suitable only for applications where the actual operating current does not exceed 2.9 A. For applications requiring the full 3.61 A rating, use B82476A1103M000, P0751.103NLT, or B82476B1103M100 instead.

Q: Is the higher DC resistance of P0751.103NLT (50mOhm vs. 28.3mOhm) a concern?

A: The DC resistance specification of 50mOhm is higher than the original 28.3mOhm. This parameter affects power dissipation and thermal performance. Evaluate this difference against your application's thermal budget and efficiency requirements. If thermal performance is critical, B82476A1103M000 or B82476B1103M100 with 27mOhm DCR are preferred alternatives.

Q: Can B82476B1103M100 be used in automotive applications?

A: Yes. The B82476B1103M100 carries AEC-Q200 qualification, indicating compliance with automotive-grade reliability standards. This component is suitable for automotive and other mission-critical applications requiring enhanced reliability certification.

Q: What is the physical size compatibility between substitute parts and the original UP2C-100-R?

A: All substitute parts have dimensions within 0.02" (0.5mm) of the original UP2C-100-R in length and width, with height variations within 0.018" (0.46mm). These dimensional tolerances are within standard PCB layout and assembly margins for surface mount components. Verify final PCB layout clearances for your specific application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts (B82476A1103M000, P0751.103NLT, B82476B1103M100, P0751.103NL, and SDR1005-100ML) are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the inductance test frequency difference between SDR1005-100ML and other substitutes?

A: The SDR1005-100ML is tested at 1 kHz, while the original UP2C-100-R and all other substitutes are tested at 100 kHz. This difference reflects different measurement methodologies. For applications requiring 100 kHz test frequency alignment, use B82476A1103M000, P0751.103NLT, B82476B1103M100, or P0751.103NL.

Q: Which substitute offers the best thermal performance?

A: B82476A1103M000 and B82476B1103M100 both provide DC resistance of 27mOhm, which is lower than the original 28.3mOhm and significantly lower than P0751.103NLT and SDR1005-100ML at 50mOhm. Lower DC resistance results in reduced power dissipation and improved thermal performance. B82476B1103M100 additionally provides higher current rating (4.3 A) for enhanced thermal margin.
