UP5S-151-R Equivalent & Substitute Parts

Part Overview

The UP5S-151-R is a 150 µH shielded wirewound surface mount inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 5S series. This component is rated for 1.35 A continuous current with a maximum DC resistance of 220mOhm and operates across the temperature range of -25°C to 85°C. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching package form factors are available from alternative manufacturers. Substitution becomes necessary for supply chain continuity, inventory optimization, or when primary sources experience allocation constraints.

Substitute Part Grouping Explanation

Substitute parts for the UP5S-151-R are identified based on the following substitution criteria:

Primary Matching Parameters:

• Inductance value: 150 µH (exact match required)
• Current rating: Equal to or greater than 1.35 A
• DC resistance: Not exceeding 250mOhm maximum
• Saturation current: Equal to or greater than 2.0 A
• Mounting type: Surface Mount (SMD)
• Package dimensions: Nonstandard form factor within acceptable PCB footprint tolerance
• Regulatory compliance: RoHS3 compliant, MSL 1 rating

Secondary Considerations:

• Operating temperature range compatibility with application requirements
• Shielding characteristics (shielded vs. unshielded) based on EMI/RFI environment
• Inductance frequency test point: 100 kHz (standard measurement condition)

The substitute part P0250.154NLT from Pulse Electronics meets the core electrical and mechanical substitution criteria while maintaining regulatory compliance and active product status.

Engineering Selection Recommendations

UP5S-151-R (Primary Selection):

• Recommended when shielded inductor characteristics are required for EMI/RFI suppression
• Suitable for applications operating within -25°C to 85°C temperature range
• Preferred when self-resonant frequency specification at 5 MHz is a design requirement
• Active product status with established supply chain through Eaton

P0250.154NLT (Substitute Selection):

• Acceptable substitute when shielding is not a circuit requirement
• Suitable for applications requiring extended temperature operation (-40°C to 130°C)
• Provides higher current rating (1.5 A vs. 1.35 A) and saturation current margin (2.6 A vs. 2.0 A)
• Tighter inductance tolerance (±15% vs. ±20%) may benefit precision applications
• Active product status with established supply chain through Pulse Electronics
• Both parts maintain RoHS3 compliance and MSL 1 rating

Substitution Constraints:

• Shielding difference must be evaluated against circuit EMI/RFI environment
• PCB footprint dimensions are within acceptable tolerance but should be verified against layout constraints
• DC resistance difference (30 mOhm) may affect thermal performance in high-current applications

Frequently Asked Questions (FAQ)

Q: Can P0250.154NLT directly replace UP5S-151-R in all applications?

A: Direct replacement is possible when the circuit does not require shielded inductor characteristics. The unshielded design of P0250.154NLT may introduce EMI/RFI coupling in sensitive applications. Electrical parameters (inductance, current rating, saturation current) are compatible. PCB footprint dimensions are within tolerance.

Q: What is the significance of the shielding difference?

A: UP5S-151-R is shielded, which reduces electromagnetic field radiation and susceptibility to external interference. P0250.154NLT is unshielded. Selection depends on circuit layout, proximity to sensitive components, and EMI/RFI environment. Shielding is not a substitution barrier if the application does not require it.

Q: Are the package dimensions compatible?

A: Yes. UP5S-151-R dimensions are 18.40 x 15.00 x 7.50 mm. P0250.154NLT dimensions are 18.62 x 15.14 x 7.36 mm. Differences are within typical PCB layout tolerance. Verify against specific footprint requirements before implementation.

Q: Does the higher current rating of P0250.154NLT affect compatibility?

A: No. Higher current rating (1.5 A vs. 1.35 A) and saturation current (2.6 A vs. 2.0 A) provide additional performance margin. The substitute can safely handle the design current of the original part.

Q: What is the impact of the 30 mOhm DC resistance difference?

A: UP5S-151-R has 220 mOhm maximum DCR; P0250.154NLT has 250 mOhm maximum. The 30 mOhm difference results in approximately 13.6% higher power dissipation at rated current (1.35 A). In thermal-sensitive applications, verify that the substitute's thermal performance remains acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes. Both UP5S-151-R and P0250.154NLT are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both meet regulatory requirements for restricted substance use.

Q: What is the temperature range consideration for substitution?

A: UP5S-151-R operates -25°C to 85°C. P0250.154NLT operates -40°C to 130°C. If the application requires extended temperature operation beyond 85°C, P0250.154NLT provides additional capability. For standard -25°C to 85°C applications, both are suitable.

Q: Are both parts actively manufactured?

A: Yes. Both UP5S-151-R (Eaton) and P0250.154NLT (Pulse Electronics) maintain Active product status, indicating ongoing manufacturing and availability through authorized distributors.
