Key Parameters

Substitute Part Grouping Explanation

Substitute components for the UP2SC-470-R are qualified based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 47 µH (exact match required)
• Shielding: Shielded construction
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Current rating: Equal to or greater than 1 A
• DC resistance: Equal to or less than 190 mOhm
• Operating temperature range: Must encompass or extend the original -25°C to 85°C range
• Inductance tolerance: ±15% or tighter

The identified substitute parts meet these criteria while offering improved or equivalent electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

DR1040-470-R (Eaton - Electronics Division): This substitute offers superior electrical performance with 1.9 A current rating and reduced DC resistance of 128 mOhm maximum, providing improved thermal characteristics. The extended operating temperature range of -40°C to 125°C exceeds the original specification. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Physical dimensions are slightly smaller (0.413" L x 0.406" W, 0.157" height), which may require PCB layout verification. The ±30% inductance tolerance is wider than the original ±15%, requiring circuit tolerance analysis. Product status is active with established supply chain availability.

SRR1005-470Y (Bourns Inc.): This substitute provides direct electrical equivalence with matching 1 A current rating and 190 mOhm maximum DC resistance. Inductance tolerance matches the original specification at ±15%. Physical dimensions and height are identical to the UP2SC-470-R, facilitating direct PCB footprint compatibility. Extended operating temperature range of -40°C to 125°C exceeds original requirements. The component is ROHS3 compliant and REACH unaffected. Product status is active with established supply availability. This option presents the lowest risk for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the DR1040-470-R replace the UP2SC-470-R in all applications?

A: The DR1040-470-R meets the core electrical requirements of 47 µH inductance and shielded construction. However, the wider inductance tolerance (±30% versus ±15%) and different saturation current (2.1 A versus 1.61 A) require circuit-level analysis. The smaller physical dimensions (0.413" L x 0.406" W versus 0.500" L x 0.394" W) necessitate PCB layout verification. Applications with tight inductance tolerance requirements should evaluate circuit performance impact.

Q: Is the SRR1005-470Y a direct replacement for the UP2SC-470-R?

A: The SRR1005-470Y provides the closest electrical match with identical current rating (1 A), DC resistance (190 mOhm maximum), and inductance tolerance (±15%). Physical dimensions and height are identical, supporting direct PCB footprint compatibility. Both components are shielded surface mount inductors with MSL 1 rating. The primary difference is manufacturer (Bourns versus Eaton) and extended operating temperature range (-40°C to 125°C versus -25°C to 85°C).

Q: What are the key differences between wirewound and drum core construction?

A: The UP2SC-470-R uses wirewound construction, while both substitute parts employ drum core wirewound construction. Drum core designs typically offer improved thermal performance and higher current handling capability. The functional inductance value, shielding effectiveness, and DC resistance characteristics remain comparable across these construction types when electrical specifications match.

Q: How do inductance tolerance differences affect circuit design?

A: The UP2SC-470-R and SRR1005-470Y specify ±15% inductance tolerance, while the DR1040-470-R specifies ±30%. In circuits where inductance value directly affects frequency response, filtering characteristics, or impedance matching, the wider tolerance of the DR1040-470-R may introduce unacceptable performance variation. Applications with tight frequency or impedance requirements should prioritize the SRR1005-470Y or verify DR1040-470-R performance across the full tolerance range.

Q: Are there packaging considerations for these substitutes?

A: The UP2SC-470-R packaging information is not specified in available data. Both substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. Verify that your procurement and assembly processes support TR packaging format.

Q: What is the significance of the extended operating temperature range?

A: Both substitute parts operate across -40°C to 125°C, compared to the original -25°C to 85°C range. This extended range provides additional design margin for applications subject to extreme environmental conditions. However, if your application operates only within the original temperature range, this extended capability does not provide functional advantage.

Q: How do saturation current ratings affect component selection?

A: The UP2SC-470-R has Isat of 1.61 A, the DR1040-470-R has Isat of 2.1 A, and the SRR1005-470Y has Isat of 1.3 A. Saturation current represents the point at which inductance begins to degrade under increasing current. The SRR1005-470Y's lower Isat (1.3 A) provides less margin above the 1 A rated current. Applications approaching maximum current ratings should consider the DR1040-470-R for improved headroom.
