UP5S-102-R Equivalent & Substitute Parts

Part Overview

The UP5S-102-R is a 1 mH shielded wirewound surface mount inductor manufactured by Eaton - Electronics Division. This component is rated for 550 mA continuous current with a maximum DC resistance of 1.5 Ohm and operates across the temperature range of -25°C to 85°C. The part is classified as Active product status and is RoHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent inductance values, current ratings, and mounting specifications align within acceptable electrical and mechanical tolerances. The primary substitute for the UP5S-102-R is the P0250.105NLT from Pulse Electronics, which shares the same 1 mH inductance specification and surface mount package category.

Substitute Part Grouping Explanation

Substitution eligibility for the UP5S-102-R is determined by the following core electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 1 mH (exact match required)
• Inductance test frequency: 100 kHz
• Mounting type: Surface Mount
• Package category: Nonstandard
• Current rating: Minimum 550 mA
• Saturation current: Minimum 780 mA
• DC resistance: Within acceptable operating limits
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The P0250.105NLT from Pulse Electronics meets these core criteria with a 1 mH inductance specification, 560 mA current rating (exceeding the 550 mA requirement), and 1 A saturation current. Both parts are surface mount, nonstandard package inductors tested at 100 kHz and carry RoHS3 compliance with MSL 1 rating.

Engineering Selection Recommendations

UP5S-102-R (Eaton - Primary Component)

The UP5S-102-R is the specified component with active product status. It provides shielded construction, which reduces electromagnetic interference in sensitive circuit applications. The part carries RoHS3 compliance and MSL 1 rating, suitable for standard manufacturing and storage conditions. The operating temperature range of -25°C to 85°C covers standard industrial and commercial applications.

P0250.105NLT (Pulse Electronics - Substitute)

The P0250.105NLT is an active substitute with equivalent 1 mH inductance and surface mount configuration. This part offers improved saturation current performance (1 A versus 780 mA) and tighter inductance tolerance (±15% versus ±20%). The extended operating temperature range (-40°C to 130°C) accommodates wider environmental conditions. The unshielded design results in slightly higher DC resistance (1.8 Ohm Max versus 1.5 Ohm Max) and may introduce electromagnetic coupling in high-density layouts. Both parts are RoHS3 compliant with MSL 1 rating and carry identical ECCN and HTSUS classifications.

Selection between these parts depends on circuit requirements for electromagnetic shielding, DC resistance budget, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the P0250.105NLT replace the UP5S-102-R in all applications?

A: Both parts share identical 1 mH inductance and surface mount specifications. The primary difference is shielding: the UP5S-102-R is shielded while the P0250.105NLT is unshielded. Applications requiring EMI suppression or operating in electromagnetically sensitive environments should retain the shielded UP5S-102-R. The P0250.105NLT is suitable for applications where shielding is not a circuit requirement.

Q: What is the impact of the 0.3 Ohm difference in DC resistance?

A: The UP5S-102-R specifies 1.5 Ohm Max DCR while the P0250.105NLT specifies 1.8 Ohm Max DCR. This 0.3 Ohm difference results in increased power dissipation in the substitute part. For circuits with tight power budgets or high continuous current operation near the 550 mA rating, the lower DCR of the UP5S-102-R is preferable. For applications operating well below saturation current, this difference is typically negligible.

Q: Are the physical dimensions compatible for PCB layout?

A: The parts have similar but not identical dimensions. The UP5S-102-R measures 0.724" L x 0.591" W x 0.295" H (18.40mm x 15.00mm x 7.50mm). The P0250.105NLT measures 0.733" L x 0.596" W x 0.290" H (18.62mm x 15.14mm x 7.36mm). The differences are within 0.009" (0.22mm) for length and width, and 0.005" (0.14mm) for height. Both parts fit nonstandard package footprints and should be evaluated against specific PCB layout constraints.

Q: What is the significance of the ±15% versus ±20% tolerance difference?

A: The P0250.105NLT offers tighter inductance tolerance (±15%) compared to the UP5S-102-R (±20%). For applications requiring precise inductance values, the substitute part provides better tolerance performance. For general-purpose filtering and energy storage applications, both tolerances are typically acceptable.

Q: Do both parts support the same operating temperature range?

A: No. The UP5S-102-R operates from -25°C to 85°C, while the P0250.105NLT operates from -40°C to 130°C. For applications requiring extended low-temperature operation below -25°C or high-temperature operation above 85°C, the P0250.105NLT is required. For standard industrial temperature ranges, both parts are suitable.

Q: Are there any compliance or regulatory differences?

A: Both parts are RoHS3 compliant with MSL 1 (Unlimited) rating. Both carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications. The P0250.105NLT includes REACH Unaffected status in the provided data. From a compliance perspective, both parts are equivalent for standard applications.
