Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP5-151-R is determined by strict alignment with the following critical parameters:

Inductance Value: All substitute parts must provide exactly 150 µH at the 100 kHz test frequency. This is the primary functional specification and cannot vary.

Current Rating: Substitute parts must support a minimum continuous current rating of 1.5 A. Parts with higher current ratings are acceptable as they provide additional design margin.

DC Resistance: The maximum DC resistance specification of 250 mOhm must be met or exceeded (lower DCR values are acceptable). This parameter directly affects power dissipation and thermal performance in the circuit.

Saturation Current (Isat): Substitute parts must maintain saturation current at or above 2.6 A to ensure stable performance under transient conditions.

Mounting and Package: All substitute parts must be surface mount components with nonstandard package dimensions compatible with the original PCB layout. Physical dimensions (length, width, height) must be within acceptable tolerances for mechanical fit.

Shielding Configuration: All substitute parts must be unshielded to maintain consistent EMI characteristics and circuit behavior.

Environmental and Compliance: Substitute parts must maintain RoHS compliance status and MSL rating of 1 (Unlimited) to ensure regulatory acceptance and standard handling procedures.

Engineering Selection Recommendations

P0250.154NLT (Pulse Electronics) - Direct Equivalent:

The P0250.154NLT qualifies as a direct equivalent to the UP5-151-R. Both parts share identical inductance (150 µH), current rating (1.5 A), and DC resistance (250 mOhm Max) specifications. The P0250.154NLT features a tighter inductance tolerance of ±15% compared to the UP5-151-R's ±20%, providing improved circuit performance consistency. Physical dimensions are within acceptable tolerances for PCB compatibility. The extended operating temperature range (-40°C to 130°C) provides broader environmental coverage. Both parts maintain RoHS compliance and MSL 1 rating. The P0250.154NLT is currently Active in product status with 2000 pieces in inventory, supporting reliable supply chain access.

74458215 (Würth Elektronik) - Similar Equivalent:

The 74458215 qualifies as a similar equivalent with full functional compatibility. This part maintains the same 150 µH inductance, 1.5 A current rating, and 250 mOhm Max DC resistance. The saturation current is marginally higher at 2.7 A compared to 2.6 A, providing additional transient current margin. Physical dimensions are within acceptable tolerances. The extended operating temperature range (-40°C to 125°C) supports broader environmental applications. The 74458215 is currently Active with 1239 pieces in inventory. This part features a ferrite drum core construction, which is consistent with the unshielded wirewound category. ROHS3 compliance and MSL 1 rating align with regulatory requirements.

Selection Basis:

Both substitute parts are Active in product status, ensuring long-term availability and manufacturer support. All three parts maintain identical core electrical specifications (inductance, current rating, DC resistance) and are packaged in Tape & Reel format for automated assembly. The substitute parts offer extended operating temperature ranges, which provide design flexibility for applications requiring broader environmental performance. Inventory levels for substitute parts exceed the primary part, supporting procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the P0250.154NLT be used as a direct replacement for the UP5-151-R without circuit redesign?

A: Yes. The P0250.154NLT meets all critical electrical specifications: 150 µH inductance, 1.5 A current rating, and 250 mOhm Max DC resistance. Physical dimensions are within acceptable tolerances for PCB fit. The tighter inductance tolerance (±15% vs. ±20%) may improve circuit performance. No circuit redesign is required.

Q: What is the difference between the UP5-151-R and the 74458215 in terms of core construction?

A: The UP5-151-R uses standard wirewound construction with unspecified core material. The 74458215 uses drum core, wirewound construction with ferrite core material. Both are unshielded and deliver identical electrical performance at the specified test frequency (100 kHz). The ferrite core in the 74458215 provides consistent performance characteristics across the operating temperature range.

Q: Are there any physical fit concerns when substituting these parts on existing PCBs?

A: Physical dimensions are comparable across all three parts. The UP5-151-R measures 18.40mm x 15.00mm with 7.50mm height. The P0250.154NLT measures 18.62mm x 15.14mm with 7.36mm height. The 74458215 measures 18.54mm x 15.24mm with 7.11mm height. These variations are within standard PCB design tolerances for nonstandard packages. Verify PCB footprint clearances before final assembly.

Q: Do all substitute parts maintain the same RoHS compliance level?

A: The UP5-151-R is RoHS Compliant. Both substitute parts (P0250.154NLT and 74458215) are ROHS3 Compliant, which represents an enhanced compliance standard. ROHS3 compliance is fully compatible with RoHS requirements and provides additional regulatory assurance.

Q: What is the significance of the MSL 1 (Unlimited) rating across all parts?

A: MSL 1 (Unlimited) indicates that these components have unlimited shelf life under standard storage conditions (typically 30°C/60% RH). No special moisture control or baking procedures are required before assembly. This simplifies inventory management and reduces handling complexity.

Q: Can the 74458215 be used in applications requiring the full -25°C to 105°C temperature range of the UP5-151-R?

A: Yes. The 74458215 operates across -40°C to 125°C, which fully encompasses the -25°C to 105°C range of the UP5-151-R. The extended range provides additional design margin for temperature-sensitive applications.

Q: How do the saturation current specifications compare across these parts?

A: The UP5-151-R and P0250.154NLT both specify 2.6 A saturation current. The 74458215 specifies 2.7 A saturation current. All three parts exceed the 1.5 A continuous current rating, ensuring stable performance under transient conditions. The marginal difference (0.1 A) does not affect practical circuit design.

Q: Are all three parts available in Tape & Reel packaging for automated assembly?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, supporting standard pick-and-place assembly processes. Inventory levels are: UP5-151-R (830 Pcs), P0250.154NLT (2000 Pcs), and 74458215 (1239 Pcs).
