Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP5-220-R is permissible when the alternative component meets or exceeds the following critical electrical and mechanical parameters:

Core Substitution Criteria:

• Inductance value of 22 µH at 100 kHz test frequency
• Current rating of 3.5 A minimum
• DC resistance of 47 mOhm maximum
• Surface mount nonstandard package configuration
• Saturation current of 7 A minimum
• Operating temperature range that encompasses -25°C to 105°C
• Moisture sensitivity level of 1 (Unlimited)
• RoHS compliance status

Substitution Categories:

Direct Equivalent (P0250.223NLT): Pulse Electronics component with identical electrical specifications, tighter inductance tolerance (±15% vs ±20%), extended operating temperature range (-40°C to 130°C), and ROHS3 compliance. Mechanical dimensions are within acceptable tolerance variance.

Similar Equivalent (74458122): Würth Elektronik component with ferrite drum core construction, matching electrical specifications, identical inductance tolerance (±20%), extended operating temperature range (-40°C to 125°C), and ROHS3 compliance. Mechanical dimensions are within acceptable tolerance variance.

Conditional Equivalent (74459122): Würth Elektronik component with shielded construction, reduced current rating (3.4 A vs 3.5 A), increased DC resistance (59 mOhm vs 47 mOhm max), and reduced saturation current (6 A vs 7 A). This component is suitable only for applications where shielding is required and the reduced electrical ratings are acceptable.

Parameter Comparison

Engineering Selection Recommendations

P0250.223NLT (Pulse Electronics) - Direct Equivalent: This component is the preferred direct substitute for the UP5-220-R. It maintains identical electrical specifications with a tighter inductance tolerance of ±15%, providing improved performance consistency. The extended operating temperature range of -40°C to 130°C exceeds the original specification, offering greater thermal margin. ROHS3 compliance and REACH Unaffected status provide enhanced regulatory alignment. Mechanical dimensions are within acceptable tolerance variance for PCB layout compatibility. This component is suitable for direct replacement in all applications where the UP5-220-R is specified.

74458122 (Würth Elektronik) - Similar Equivalent: This component provides equivalent electrical performance with ferrite drum core construction. The inductance tolerance of ±20% matches the original specification. The extended operating temperature range of -40°C to 125°C provides thermal margin beyond the original -25°C to 105°C range. ROHS3 compliance and REACH Unaffected status meet current regulatory requirements. Mechanical dimensions are within acceptable tolerance variance. This component is suitable for applications where the original UP5-220-R specifications are met and ferrite core construction is acceptable.

74459122 (Würth Elektronik) - Conditional Equivalent: This component is suitable only for applications where shielded inductor construction is required. The reduced current rating of 3.4 A (versus 3.5 A), increased DC resistance of 59 mOhm (versus 47 mOhm max), and reduced saturation current of 6 A (versus 7 A) represent electrical derating. This component is not a direct substitute for the UP5-220-R in applications requiring the full 3.5 A current rating or 47 mOhm maximum DC resistance specification. Use only when shielding requirements justify the electrical parameter reduction.

Frequently Asked Questions (FAQ)

Q: Can P0250.223NLT be used as a direct replacement for UP5-220-R?

A: Yes. The P0250.223NLT meets all critical electrical specifications of the UP5-220-R with identical inductance (22 µH), current rating (3.5 A), DC resistance (47 mOhm max), and saturation current (7 A). The tighter inductance tolerance (±15%) and extended operating temperature range provide performance advantages. Mechanical dimensions are within acceptable tolerance variance for PCB layout compatibility.

Q: What is the difference between 74458122 and 74459122?

A: The 74458122 is an unshielded component with specifications matching the UP5-220-R (3.5 A current rating, 47 mOhm max DCR, 7 A saturation current). The 74459122 is a shielded component with reduced electrical ratings (3.4 A current rating, 59 mOhm max DCR, 6 A saturation current). The shielding in 74459122 introduces electromagnetic isolation but at the cost of reduced current handling capability and increased DC resistance.

Q: Are all substitute parts RoHS compliant?

A: Yes. The UP5-220-R is RoHS Compliant. All substitute parts (P0250.223NLT, 74458122, and 74459122) are ROHS3 Compliant, which represents an enhanced compliance standard. All components meet current regulatory requirements for hazardous substance restrictions.

Q: What are the mechanical compatibility considerations?

A: All components are surface mount nonstandard package types with Tape & Reel (TR) packaging. Mechanical dimensions vary slightly: UP5-220-R (18.40mm x 15.00mm x 7.50mm max height), P0250.223NLT (18.62mm x 15.14mm x 7.36mm max height), 74458122 (18.54mm x 15.24mm x 7.11mm max height), and 74459122 (18.54mm x 15.24mm x 7.62mm max height). These dimensional variations are within acceptable tolerance for standard PCB layout practices. Verify footprint compatibility with your specific PCB design.

Q: Which substitute part has the best temperature performance?

A: The P0250.223NLT offers the widest operating temperature range at -40°C to 130°C, compared to the original UP5-220-R range of -25°C to 105°C. Both Würth components (74458122 and 74459122) operate from -40°C to 125°C. All components maintain MSL rating of 1 (Unlimited) for moisture sensitivity.

Q: Can 74459122 be used in place of UP5-220-R?

A: The 74459122 is not a direct substitute due to reduced electrical ratings. The current rating is reduced to 3.4 A (versus 3.5 A), DC resistance is increased to 59 mOhm max (versus 47 mOhm max), and saturation current is reduced to 6 A (versus 7 A). Use 74459122 only in applications where shielded inductor construction is required and these reduced electrical parameters are acceptable for your circuit design.

Q: What is the inductance tolerance difference between parts?

A: The UP5-220-R and 74458122 and 74459122 all have ±20% inductance tolerance. The P0250.223NLT has a tighter ±15% tolerance, providing improved inductance value consistency and potentially better circuit performance in applications sensitive to inductance variation.

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

A: Yes. All components (UP5-220-R, P0250.223NLT, 74458122, and 74459122) are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
