UP2.8B-221-R Equivalent & Substitute Parts

Part Overview

The UP2.8B-221-R is a 220 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, rated for 500 mA continuous current operation. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part operates across the temperature range of -40°C to 85°C and is suitable for surface mount applications in nonstandard package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP2.8B-221-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 220 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Core material compatibility: Ferrite or equivalent wirewound construction

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 500 mA continuous operation
• Operating temperature range: Substitute must cover or exceed -40°C to 85°C
• Physical footprint: Nonstandard package with dimensions approximately 12.90mm × 9.40mm × 2.80mm maximum height
• Moisture sensitivity: MSL 1 (Unlimited)

The P0762.224NLT from Pulse Electronics satisfies these substitution criteria through matching inductance specification, unshielded wirewound construction, surface mount configuration, and compatible physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The P0762.224NLT qualifies as a functional equivalent for the obsolete UP2.8B-221-R based on matching inductance value, tolerance, unshielded configuration, and surface mount compatibility. The substitute is actively manufactured and maintains MSL 1 classification.

Design Considerations:

The P0762.224NLT exhibits a continuous current rating of 400 mA, which is 100 mA lower than the original 500 mA specification. Applications requiring the full 500 mA continuous current capacity must evaluate whether the substitute's saturation current rating of 500 mA provides adequate margin for the intended circuit operation. The substitute's maximum height of 3.00mm exceeds the original 2.80mm by 0.20mm; PCB layout clearance must be verified for space-constrained applications.

Compliance Status:

The P0762.224NLT carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for modern manufacturing environments. Both components share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Temperature Performance:

The substitute's extended operating range to 130°C provides additional thermal margin beyond the original -40°C to 85°C specification, supporting applications in elevated ambient conditions.

Frequently Asked Questions (FAQ)

Q: Can the P0762.224NLT directly replace the UP2.8B-221-R in all applications?

A: Direct replacement is feasible for applications where continuous current demand does not exceed 400 mA. The substitute's saturation current of 500 mA accommodates transient current peaks. Applications requiring sustained 500 mA operation must evaluate circuit performance with the lower continuous rating.

Q: What is the significance of the 0.20mm height difference?

A: The P0762.224NLT maximum seated height of 3.00mm versus the original 2.80mm represents a 0.20mm increase. This difference is negligible for most PCB designs but must be verified in space-constrained applications, particularly where component stacking or clearance to adjacent circuitry is critical.

Q: Are the physical dimensions otherwise compatible?

A: Yes. The length and width dimensions are functionally equivalent (12.95mm versus 12.90mm length, and 9.40mm width for both). The dimensional variance of 0.05mm in length is within typical manufacturing tolerance and does not affect PCB footprint compatibility.

Q: What is the impact of the unspecified DC resistance in the original part?

A: The original UP2.8B-221-R does not provide DC resistance specification. The P0762.224NLT specifies 1.9 Ohm maximum DCR, enabling precise circuit analysis for applications where resistive losses affect performance. This additional specification data supports more accurate circuit modeling.

Q: How do the inductance test frequencies compare?

A: Both components specify inductance measurement at 100 kHz, ensuring direct inductance value equivalence at the same reference frequency.

Q: Is the substitute suitable for high-temperature applications?

A: The P0762.224NLT operating range extends to 130°C, compared to the original 85°C maximum. This extended range supports applications in elevated ambient or self-heating environments beyond the original specification.

Q: What packaging format is the substitute supplied in?

A: The P0762.224NLT is supplied in Tape & Reel (TR) format, standard for automated assembly processes. The original part packaging format is not specified in the provided data.
