UP0.4SC-220-R Equivalent & Substitute Parts

Part Overview

The UP0.4SC-220-R is a 22 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, designed for surface mount applications requiring 700 mA current handling capability. This component is classified as Active product status and is RoHS Compliant. Equivalent parts are identified when applications require alternative sourcing, inventory availability, or supply chain continuity while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP0.4SC-220-R is permissible with parts meeting the following criteria:

Critical Electrical Parameters (Must Match):

• Inductance: 22 µH
• Inductance Tolerance: ±20%
• Current Rating: 700 mA
• DC Resistance: 110 mOhm Max
• Shielding: Shielded
• Q Factor @ 100 kHz: 40
• Self Resonant Frequency: 25 MHz
• Inductance Test Frequency: 100 kHz

Critical Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package Type: Nonstandard
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variations:

• Operating Temperature Range: Substitute may exceed the original range
• Core Material: May differ (ferrite, iron powder, etc.)
• Physical Dimensions: Minor variations acceptable within nonstandard package classification
• Compliance Standards: Substitute must maintain RoHS compliance or equivalent

The SRR6603-220ML from Bourns Inc. satisfies all critical parameters and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: UP0.4SC-220-R (Eaton)

Use the original UP0.4SC-220-R when:

• Eaton component qualification is required by design specification
• Existing inventory or supply agreements are in place
• Operating temperature range does not exceed -40°C ~ 125°C

Alternative Selection: SRR6603-220ML (Bourns)

Use the SRR6603-220ML when:

• Supply continuity of the UP0.4SC-220-R is unavailable
• Extended low-temperature operation to -55°C is required
• Bourns component qualification is acceptable per design documentation
• ROHS3 compliance certification is preferred over RoHS Compliant status

Both components maintain Active product status and are in current production. Physical dimensions are functionally equivalent within nonstandard package tolerances. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-220ML be used as a direct replacement for UP0.4SC-220-R?

A: Yes. Both components share identical electrical specifications: 22 µH inductance, ±20% tolerance, 700 mA current rating, 110 mOhm maximum DC resistance, 40 Q factor at 100 kHz, and 25 MHz self-resonant frequency. Physical dimensions are functionally equivalent for surface mount applications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Eaton vs. Bourns), core material type (unspecified vs. ferrite drum core), operating temperature range (-40°C ~ 125°C vs. -55°C ~ 125°C), and compliance certification (RoHS Compliant vs. ROHS3 Compliant). Electrical performance is identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: Physical dimensions are nearly identical (length 6.60mm, width 4.45mm vs. 4.40mm, height 2.92mm vs. 3.00mm). PCB footprints designed for the UP0.4SC-220-R accommodate the SRR6603-220ML without modification. Both components are surface mount, nonstandard package types.

Q: Which part should be selected for new designs?

A: Either component is acceptable for new designs. Selection should be based on manufacturer qualification requirements, supply chain preferences, and temperature operating range needs. The SRR6603-220ML provides extended low-temperature capability (-55°C minimum vs. -40°C).

Q: Are moisture sensitivity levels identical?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage, handling, or assembly.

Q: What is the saturation current difference?

A: The UP0.4SC-220-R does not specify saturation current. The SRR6603-220ML specifies 300 mA saturation current. This parameter does not affect substitution eligibility as the 700 mA current rating remains the controlling specification for both parts.
