UP2B-220 Equivalent & Substitute Parts Reference

Part Overview

The UP2B-220 is a 22 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division, rated for 2.8 A continuous current with a maximum DC resistance of 61.7 mOhm. This component is classified as obsolete product status. Due to its obsolete designation, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the UP2B-220 is determined by the following critical parameters:

Primary Matching Criteria:

Inductance value: 22 µH (exact match required)
Tolerance: ±20% (standard tolerance match)
Test frequency: 100 kHz (measurement standard match)
Mounting type: Surface Mount (form factor requirement)
Core material: Ferrite (electrical performance baseline)

Secondary Compatibility Factors:

Current rating: Minimum 2.8 A (equal or higher acceptable)
DC resistance: Maximum 61.7 mOhm (lower values acceptable; higher values require thermal analysis)
Operating temperature: Minimum -40°C ~ 85°C (wider ranges acceptable)
Shielding configuration: Unshielded preferred for direct replacement; shielded variants acceptable with EMI consideration

Substitute parts are grouped into two categories: direct equivalents (matching all primary criteria with active product status) and functional alternatives (meeting electrical specifications with minor parameter variations).

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility):

UP2B-220-R is the primary recommended substitute. This part is manufactured by the same supplier (Eaton - Electronics Division) and maintains identical electrical specifications to the obsolete UP2B-220. The only differences are active product status and ROHS3 compliance certification, making it a direct form-fit-function replacement. Tape & Reel packaging is standard for production environments.

Unshielded Alternatives (Electrical Equivalence):

AX97-30220 (Triad Magnetics) and P0751.223NL (Pulse Electronics) are unshielded alternatives matching the original shielding configuration. AX97-30220 provides higher current rating (3.1 A versus 2.8 A) with slightly elevated DCR (70 mOhm). P0751.223NL offers the widest operating temperature range (-40°C ~ 130°C) but exhibits higher DCR (114 mOhm), requiring thermal verification in current-limited applications.

Shielded Alternatives (EMI Mitigation):

CDRH124NP-220MC, CDMPIH10D48T125NP-220MC, and IDCS7328ER220M are shielded variants suitable for applications requiring electromagnetic interference suppression. IDCS7328ER220M (Vishay Dale) offers the lowest DCR (59 mOhm) and highest current rating (3.1 A) with extended temperature range (-40°C ~ 125°C). CDMPIH10D48T125NP-220MC includes AEC-Q200 automotive qualification. Selection of shielded variants requires confirmation that PCB layout and circuit topology accommodate the modified package dimensions.

Compliance Considerations:

All recommended substitutes carry ROHS3 compliance certification except CDMPIH10D48T125NP-220MC. For applications subject to RoHS regulatory requirements, UP2B-220-R, AX97-30220, CDRH124NP-220MC, IDCS7328ER220M, and P0751.223NL are qualified selections.

Frequently Asked Questions (FAQ)

Q: Can UP2B-220-R be used as a direct replacement for UP2B-220?

A: Yes. UP2B-220-R is manufactured by Eaton - Electronics Division with identical electrical specifications (22 µH, 2.8 A, 61.7 mOhm DCR) and unshielded configuration. The primary differences are active product status and ROHS3 compliance. This is the recommended primary substitute.

Q: What is the difference between shielded and unshielded substitute options?

A: Unshielded variants (UP2B-220-R, AX97-30220, P0751.223NL) maintain the original electromagnetic profile and are suitable for applications without EMI constraints. Shielded variants (CDRH124NP-220MC, CDMPIH10D48T125NP-220MC, IDCS7328ER220M) reduce radiated emissions and are required in noise-sensitive circuits. Shielded parts typically have larger physical dimensions and may require PCB layout modifications.

Q: Are there current rating differences between substitutes?

A: Yes. The UP2B-220 is rated for 2.8 A continuous current. Substitute options range from 2.6 A (P0751.223NL) to 3.1 A (AX97-30220, IDCS7328ER220M). Parts with lower ratings require circuit verification; parts with higher ratings provide design margin. DC resistance variations (59 mOhm to 114 mOhm) affect thermal performance and must be evaluated in power-dissipation-critical applications.

Q: What packaging formats are available?

A: UP2B-220-R is supplied in Tape & Reel (TR) format, standard for production assembly. CDRH124NP-220MC is available in Cut Tape (CT) & Digi-Reel® format. AX97-30220 is supplied in Box packaging. P0751.223NL packaging format is not specified in available data. Confirm packaging compatibility with assembly equipment before procurement.

Q: Which substitute offers the widest operating temperature range?

A: P0751.223NL (Pulse Electronics) operates across -40°C ~ 130°C, providing the widest temperature margin. IDCS7328ER220M and CDMPIH10D48T125NP-220MC both support -40°C ~ 125°C. The original UP2B-220 specification is -40°C ~ 85°C. Selection depends on application thermal environment requirements.

Q: Is AEC-Q200 automotive qualification available?

A: Yes. CDMPIH10D48T125NP-220MC (Sumida America Components Inc.) carries AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications. Other substitutes do not list this certification in provided data.

Q: How does DC resistance affect component selection?

A: DC resistance determines resistive losses and heat generation. Lower DCR values reduce power dissipation. IDCS7328ER220M has the lowest DCR (59 mOhm), while P0751.223NL has the highest (114 mOhm). In current-limited or thermally constrained designs, lower DCR variants are preferred. In applications with minimal current flow, DCR differences are negligible.
