Engineering Selection Recommendations

Direct Equivalent - P0250.473NLT (Pulse Electronics):

The P0250.473NLT from Pulse Electronics represents a direct electrical equivalent with tighter inductance tolerance (±15% versus ±20%). This part maintains identical current ratings, saturation current, and DC resistance specifications. The extended operating temperature range (-40°C to 130°C) provides broader thermal coverage compared to the UP5-470-R. Physical dimensions are within acceptable tolerance for nonstandard package compatibility. ROHS3 compliance status confirms environmental qualification. This substitute is suitable for applications where the primary design parameters are met and extended temperature operation is beneficial.

Compatible Substitute - 74458147 (Würth Elektronik):

The 74458147 from Würth Elektronik is a drum core wirewound inductor with ferrite core material, matching all critical electrical specifications. The part maintains ±20% inductance tolerance, 2.6 A current rating, and 86 mOhm maximum DC resistance. Operating temperature range extends to -40°C to 125°C. The self-resonant frequency of 8.4 MHz is within acceptable variance of the primary part's 9 MHz specification. Physical dimensions show minimal variation in height (7.11 mm versus 7.50 mm), confirming mechanical compatibility. ROHS3 and REACH compliance status meet modern environmental standards. This substitute is appropriate for designs requiring ferrite core construction.

Compatible Substitute - ASPI-1306T-470M-T (Abracon LLC):

The ASPI-1306T-470M-T from Abracon LLC is a drum core wirewound inductor with ferrite core material, providing electrical equivalence across all primary specifications. Inductance tolerance, current rating, saturation current, and DC resistance match the primary part exactly. The self-resonant frequency of 9 MHz aligns with the UP5-470-R specification. Operating temperature range is -40°C to 85°C, which covers the primary part's minimum operating temperature but does not extend to the maximum 105°C specification. Physical dimensions are compatible with nonstandard package requirements. ROHS3 and REACH compliance status confirm environmental qualification. This substitute is suitable for applications operating within the -40°C to 85°C temperature window.

Selection Criteria Summary:

All substitute parts maintain Active product status and meet RoHS compliance requirements. Selection between substitutes depends on specific application temperature requirements and core material preferences. The Pulse Electronics P0250.473NLT offers the widest operating temperature range. The Würth Elektronik and Abracon parts provide ferrite core construction alternatives. Dimensional variations are minimal across all options, confirming mechanical interchangeability within the nonstandard package specification.

Frequently Asked Questions (FAQ)

Q: Can the P0250.473NLT replace the UP5-470-R in all applications?

A: The P0250.473NLT is electrically equivalent with matching inductance, current rating, saturation current, and DC resistance specifications. The tighter inductance tolerance (±15%) and extended operating temperature range (-40°C to 130°C) make it suitable for most applications. Physical dimensions are within acceptable tolerance for the nonstandard package footprint. Verification of specific application temperature and tolerance requirements is necessary before substitution.

Q: What is the difference between the Würth Elektronik and Abracon substitutes?

A: Both the 74458147 (Würth) and ASPI-1306T-470M-T (Abracon) are drum core wirewound inductors with ferrite cores, providing identical electrical specifications to the primary part. The primary difference is operating temperature range: Würth extends to 125°C while Abracon extends only to 85°C. Both maintain ±20% inductance tolerance and all current specifications. Physical dimensions are nearly identical between these two parts.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes, all substitute parts listed are supplied in Tape & Reel (TR) packaging format, matching the primary part's packaging specification. This ensures compatibility with automated assembly processes and standard component handling procedures.

Q: What is the significance of the inductance tolerance differences?

A: The UP5-470-R, 74458147, and ASPI-1306T-470M-T specify ±20% inductance tolerance, while the P0250.473NLT specifies ±15% tolerance. Tighter tolerance (±15%) provides more precise inductance values within the specified range. Applications requiring strict inductance accuracy may benefit from the P0250.473NLT. Applications with ±20% tolerance requirements are satisfied by all four parts.

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

A: The UP5-470-R and ASPI-1306T-470M-T specify 9 MHz self-resonant frequency, while the 74458147 specifies 8.4 MHz. The P0250.473NLT does not specify this parameter. Self-resonant frequency affects inductor behavior at high frequencies. Applications operating significantly below these frequencies are not affected by these variations. High-frequency circuit designs should verify self-resonant frequency compatibility with specific application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts meet RoHS compliance requirements. The UP5-470-R is RoHS Compliant, while the P0250.473NLT, 74458147, and ASPI-1306T-470M-T are ROHS3 Compliant. ROHS3 represents the current RoHS standard. All parts meet environmental and regulatory requirements for modern electronic applications.

Q: What are the moisture sensitivity implications?

A: All parts, including the primary UP5-470-R and all substitutes, specify Moisture Sensitivity Level (MSL) 1 with Unlimited shelf life. This classification indicates minimal moisture sensitivity and no special storage or handling requirements beyond standard component practices. All parts are suitable for standard manufacturing environments without additional moisture control measures.

Q: Can physical dimension variations affect PCB layout?

A: Physical dimensions vary slightly across the four parts. The UP5-470-R measures 0.724" L × 0.591" W × 0.295" H (max seated). Substitutes range from 0.730" to 0.733" in length, 0.596" to 0.600" in width, and 0.280" to 0.290" in height. These variations are within typical PCB layout tolerances for nonstandard package components. PCB designs with tight spatial constraints should verify specific dimension compatibility before substitution.
