Substitute Part Grouping Explanation

Substitute parts for the UP2C-471-R are identified based on the following substitution criteria:

Primary Matching Criteria:

• Inductance value: 470 µH (exact match required)
• Core type: Drum core or wirewound construction
• Shielding: Unshielded configuration
• Mounting: Surface mount technology
• Package form factor: Nonstandard drum core geometry

Secondary Compatibility Criteria:

• Current rating: Substitute must support minimum 560 mA continuous operation
• DC resistance: Lower or equivalent DCR values acceptable
• Operating temperature: Minimum range -40°C to 85°C; extended ranges acceptable
• Regulatory compliance: RoHS Compliant or ROHS3 Compliant status required
• Moisture sensitivity: MSL 1 (Unlimited) rating maintained

Identified Substitutes:

1. SDR1005-471KL (Bourns Inc.) — Direct manufacturer substitute with improved tolerance (±10% vs ±20%) and extended temperature range to 125°C. Current rating of 450 mA is below the main part specification but saturation current of 500 mA provides operational margin.

2. P0752.474NLT (Pulse Electronics) — Similar substitute with 500 mA current rating and extended temperature range to 130°C. DC resistance of 1.46 Ohm Max is higher than the main part but within acceptable operational parameters.

Engineering Selection Recommendations

UP2C-471-R (Eaton - Primary Component)

The UP2C-471-R remains the specified component for applications requiring the exact 560 mA current rating and 1.191 Ohm DCR specification. Active product status and RoHS Compliance confirm ongoing manufacturer support and regulatory alignment. This component is suitable for designs operating within the -40°C to 85°C temperature envelope.

SDR1005-471KL (Bourns - Direct Substitute)

The SDR1005-471KL serves as a direct substitute when extended temperature operation to 125°C is required. The improved inductance tolerance of ±10% provides tighter circuit performance. The 450 mA current rating is below the main part specification; however, the 500 mA saturation current and ROHS3 Compliance status support use in applications where continuous current demand does not exceed 450 mA. Dimensional compatibility is maintained with slightly reduced height (5.00 mm vs 5.20 mm).

P0752.474NLT (Pulse Electronics - Alternative Substitute)

The P0752.474NLT provides an alternative substitute with extended temperature range to 130°C and 500 mA current rating. The 1.46 Ohm Max DCR is higher than the main part, resulting in increased power dissipation. ROHS3 Compliance and unlimited MSL rating confirm regulatory suitability. Dimensional compatibility is maintained with slightly increased height (5.46 mm vs 5.20 mm).

Selection Basis:

• All substitutes maintain Active product status and current manufacturer support
• All substitutes comply with RoHS requirements (RoHS Compliant or ROHS3 Compliant)
• All substitutes maintain MSL 1 (Unlimited) moisture sensitivity rating
• Dimensional compatibility is preserved across all options for PCB assembly
• Substitutes are selected based on inductance value match, unshielded configuration, and surface mount compatibility

Frequently Asked Questions (FAQ)

Q: Can SDR1005-471KL replace UP2C-471-R in all applications?

A: The SDR1005-471KL is suitable for applications where continuous current demand does not exceed 450 mA. The main part UP2C-471-R is rated for 560 mA continuous current. If your circuit requires the full 560 mA rating, the SDR1005-471KL is not a direct replacement. However, if your actual operating current is below 450 mA, the SDR1005-471KL is compatible.

Q: What is the impact of higher DC resistance in substitute parts?

A: The P0752.474NLT has a maximum DCR of 1.46 Ohm compared to the UP2C-471-R at 1.191 Ohm. Higher DC resistance increases power dissipation according to P = I²R. At 500 mA, the P0752.474NLT dissipates approximately 0.365 W compared to 0.298 W for the UP2C-471-R. This difference must be evaluated in thermal budget calculations for your specific application.

Q: Are the physical dimensions compatible for PCB assembly?

A: All three components are surface mount inductors with nonstandard drum core packages. The SDR1005-471KL has dimensions of 12.70 x 10.00 mm with 5.00 mm height. The P0752.474NLT has dimensions of 12.95 x 9.40 mm with 5.46 mm height. The UP2C-471-R has dimensions of 12.90 x 9.40 mm with 5.20 mm height. Minor dimensional variations exist; verify PCB footprint clearance and height constraints before substitution.

Q: What is the difference between ±20% and ±10% inductance tolerance?

A: The SDR1005-471KL offers ±10% inductance tolerance compared to ±20% for the UP2C-471-R and P0752.474NLT. Tighter tolerance means the actual inductance value will be closer to the nominal 470 µH specification. For applications sensitive to inductance variation, the SDR1005-471KL provides improved performance consistency.

Q: Can I use these substitutes in high-temperature applications?

A: The SDR1005-471KL operates to 125°C and the P0752.474NLT operates to 130°C, both exceeding the UP2C-471-R specification of 85°C. If your application requires operation above 85°C, either substitute is suitable. Verify that other circuit components also support the extended temperature range.

Q: Are all parts RoHS Compliant?

A: Yes. The UP2C-471-R is RoHS Compliant. The SDR1005-471KL and P0752.474NLT are both ROHS3 Compliant, which represents an updated RoHS standard. All three components meet current regulatory requirements for lead-free and restricted substance compliance.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All three parts carry this rating, eliminating moisture sensitivity concerns for procurement and assembly processes.
