Substitute Part Grouping Explanation

Substitution eligibility for the UP2UC-471-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 470 µH (within ±20% tolerance band)
• Current rating: minimum 500 mA continuous
• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Packaging format: Tape & Reel (TR)

Secondary Compatibility Factors:

• DC resistance within acceptable operating limits
• Operating temperature range compatibility
• RoHS/REACH compliance status
• Moisture sensitivity level (MSL 1 - Unlimited)

The identified substitute parts P0752.474NLT and SDR1005-471KL meet the primary matching criteria. Both maintain the 470 µH inductance specification, support 500 mA current operation, utilize surface mount packaging in tape and reel format, and provide unshielded wirewound construction. Variations in DC resistance, temperature operating ranges, and core materials are documented for circuit design consideration.

Engineering Selection Recommendations

UP2UC-471-R (Eaton - Electronics Division)

Primary selection for applications requiring the specified -25°C to 85°C operating temperature range. Offers the lowest DC resistance at 1.27 Ohm maximum, minimizing power dissipation in current-limited circuits. RoHS Compliant status supports regulatory requirements. Suitable for standard industrial and consumer electronics applications within the defined temperature envelope.

P0752.474NLT (Pulse Electronics)

Extended temperature range operation (-40°C to 130°C) accommodates automotive and industrial applications requiring broader thermal performance. DC resistance of 1.46 Ohm represents a 15% increase over the primary part. ROHS3 Compliant certification meets current regulatory standards. Identical inductance tolerance (±20%) and current rating (500 mA) maintain electrical equivalence. Larger inventory availability (7502 units) supports high-volume procurement.

SDR1005-471KL (Bourns Inc.)

Ferrite drum core construction with tighter inductance tolerance (±10%) provides enhanced precision for applications requiring controlled inductance values. Operating temperature range of -40°C to 125°C extends low-temperature performance. DC resistance of 1.7 Ohm is the highest among the three options. Continuous current rating of 450 mA is 50 mA below the primary specification; saturation current remains at 500 mA. ROHS3 Compliant. Suitable for precision filtering and tuning applications where inductance tolerance is critical.

All three parts maintain unshielded wirewound construction, surface mount packaging in tape and reel format, and MSL 1 (Unlimited) moisture sensitivity rating. Selection should account for specific circuit requirements regarding DC resistance, temperature operating range, and inductance tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can P0752.474NLT directly replace UP2UC-471-R in all applications?

A: P0752.474NLT maintains equivalent inductance (470 µH), current rating (500 mA), and packaging format. The primary difference is increased DC resistance (1.46 Ohm vs. 1.27 Ohm), resulting in approximately 15% higher power dissipation. Extended operating temperature range (-40°C to 130°C) provides broader thermal compatibility. Substitution is valid for applications where the higher DC resistance and expanded temperature range do not conflict with circuit design specifications.

Q: What is the impact of DC resistance variation among these three parts?

A: DC resistance directly affects power dissipation in the inductor. At 500 mA continuous current, UP2UC-471-R dissipates 0.318 W, P0752.474NLT dissipates 0.365 W, and SDR1005-471KL dissipates 0.425 W. Applications with thermal constraints or efficiency requirements must account for these differences. Higher DC resistance increases heat generation and may require thermal management considerations in compact designs.

Q: Why does SDR1005-471KL have a lower continuous current rating (450 mA) than the other parts?

A: SDR1005-471KL utilizes ferrite drum core construction, which exhibits different thermal and saturation characteristics compared to standard wirewound designs. The 450 mA continuous rating reflects the thermal limits of this specific core material and construction. However, saturation current remains at 500 mA, allowing brief current excursions. Applications requiring sustained 500 mA operation should use UP2UC-471-R or P0752.474NLT.

Q: Are there physical footprint compatibility concerns when substituting these parts?

A: Dimensional variations exist. UP2UC-471-R and SDR1005-471KL share identical length and width (0.500" x 0.394" / 12.70mm x 10.00mm), while P0752.474NLT is slightly larger (0.510" x 0.370" / 12.95mm x 9.40mm). Height differences range from 0.197" to 0.215" (5.00mm to 5.46mm). PCB layout and clearance requirements must be verified before substitution to ensure mechanical compatibility.

Q: What is the significance of inductance tolerance differences?

A: UP2UC-471-R and P0752.474NLT specify ±20% tolerance, while SDR1005-471KL specifies ±10% tolerance. Tighter tolerance (±10%) provides more predictable inductance values across production batches, beneficial for precision filtering, resonant circuits, and tuned applications. Standard tolerance (±20%) is acceptable for general-purpose filtering and energy storage applications where inductance variation within this band does not affect circuit performance.

Q: How do the self-resonant frequency specifications affect circuit performance?

A: UP2UC-471-R specifies 3.5 MHz self-resonant frequency, while SDR1005-471KL specifies 4 MHz. P0752.474NLT does not provide this specification. Self-resonant frequency defines the upper frequency limit where the inductor behaves as a pure inductance. Applications operating near or above these frequencies experience capacitive behavior. For circuits operating well below 1 MHz, this parameter has minimal impact.

Q: Are all three parts suitable for high-volume automated assembly?

A: All three parts are packaged in Tape & Reel (TR) format with MSL 1 (Unlimited) moisture sensitivity rating, supporting automated pick-and-place assembly without special moisture control requirements. Inventory availability is adequate for high-volume production: UP2UC-471-R (1171 units), P0752.474NLT (7502 units), and SDR1005-471KL (6300 units).
