Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP5-102-R is determined by the following core electrical parameters: inductance value of 1 mH, current rating of 560 mA or greater, DC resistance of 1.8 Ohm maximum, and inductance tolerance of ±20% or tighter. All substitute parts must maintain surface mount configuration and operate within compatible temperature ranges. Mechanical dimensions and shielding characteristics are secondary considerations that may vary within acceptable limits for the application space.

The substitute parts are grouped into two categories:

Direct Equivalent (P0250.105NLT): Meets all primary electrical specifications with tighter tolerance (±15%) and extended operating temperature range (-40°C to 130°C). Dimensions vary slightly but remain within nonstandard package classification.

Similar Equivalents (7445830, 7445930): Meet core inductance and current specifications with variations in secondary parameters. Part 7445830 features a ferrite drum core with slightly higher saturation current (1.1 A). Part 7445930 operates at 600 mA current rating with 2.01 Ohm maximum DCR and includes shielding, representing a design variant rather than a direct replacement.

Parameter Comparison

Engineering Selection Recommendations

P0250.105NLT (Pulse Electronics) is the primary direct equivalent for UP5-102-R applications. This part maintains identical electrical specifications for inductance, current rating, and DC resistance while offering improved tolerance (±15% versus ±20%) and an extended operating temperature range (-40°C to 130°C). Both parts carry active product status and full RoHS compliance. The P0250.105NLT is suitable for direct substitution in designs where the extended temperature capability and tighter tolerance provide system benefits.

7445830 (Würth Elektronik WE-PD4 series) qualifies as a substitute where the ferrite drum core construction and slightly higher saturation current (1.1 A) are acceptable. This part features a smaller physical footprint (12.70 mm × 10.10 mm versus 18.40 mm × 15.00 mm) and operates across -40°C to 125°C. Selection of this part requires verification that the reduced package size accommodates board layout constraints and that the drum core construction does not introduce unacceptable electromagnetic coupling in the application.

7445930 (Würth Elektronik WE-PD3 series) represents a design variant rather than a direct equivalent. The shielded construction, 600 mA current rating, and 2.01 Ohm maximum DCR distinguish this part from the UP5-102-R specification. This part is suitable only for applications where shielding is required and the higher DCR is acceptable within circuit performance margins.

All substitute parts carry ROHS3 compliance and active product status, confirming ongoing manufacturer support and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can P0250.105NLT replace UP5-102-R in all applications?

A: P0250.105NLT meets or exceeds all primary electrical specifications of UP5-102-R (1 mH inductance, 560 mA current rating, 1.8 Ohm maximum DCR). The tighter tolerance (±15%) and extended temperature range (-40°C to 130°C) make it suitable for direct substitution. Minor dimensional variations (18.62 mm × 15.14 mm versus 18.40 mm × 15.00 mm) fall within nonstandard package classification and do not affect electrical performance.

Q: What are the key differences between 7445830 and UP5-102-R?

A: Both parts share identical inductance (1 mH), current rating (560 mA), and DC resistance (1.8 Ohm maximum). The primary differences are: 7445830 uses ferrite drum core construction versus wirewound, features a smaller package (12.70 mm × 10.10 mm), and provides slightly higher saturation current (1.1 A versus 1 A). The ferrite core may exhibit different frequency response characteristics and electromagnetic coupling behavior.

Q: Is 7445930 a suitable replacement for UP5-102-R?

A: 7445930 is not a direct equivalent. While it maintains the 1 mH inductance specification, it differs in shielding (shielded versus unshielded), current rating (600 mA versus 560 mA), DC resistance (2.01 Ohm versus 1.8 Ohm maximum), and saturation current (800 mA versus 1 A). Selection of 7445930 requires confirmation that shielding is required and that the higher DCR and lower saturation current are acceptable within circuit design margins.

Q: Are all substitute parts RoHS compliant?

A: Yes. UP5-102-R carries RoHS Compliant status. P0250.105NLT, 7445830, and 7445930 all carry ROHS3 Compliant status, confirming compliance with current regulatory requirements.

Q: What is the impact of tolerance differences between these parts?

A: UP5-102-R, 7445830, and 7445930 specify ±20% inductance tolerance. P0250.105NLT specifies ±15% tolerance, representing a tighter specification. In applications where inductance accuracy is critical, P0250.105NLT provides improved performance. In applications where ±20% tolerance is acceptable, all parts are equivalent from a tolerance perspective.

Q: Do the physical dimension differences affect PCB layout?

A: UP5-102-R measures 18.40 mm × 15.00 mm × 7.50 mm (height). P0250.105NLT measures 18.62 mm × 15.14 mm × 7.36 mm. These differences are minimal and typically do not affect PCB layout. 7445830 is significantly smaller at 12.70 mm × 10.10 mm × 7.11 mm, which may allow for more compact board designs but requires verification of footprint compatibility with existing PCB artwork.

Q: What temperature range considerations apply to substitute selection?

A: UP5-102-R operates from -25°C to 105°C. P0250.105NLT extends this to -40°C to 130°C, providing broader environmental coverage. 7445830 and 7445930 operate from -40°C to 125°C. Selection should confirm that the substitute part's temperature range meets or exceeds the application's thermal requirements.
