Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP0.4SC-222-R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 2.2 mH with ±20% tolerance
• Current rating: 100 mA minimum
• DC resistance: 8.5Ohm maximum
• Q factor: 50 @ 100kHz
• Self resonant frequency: 2 MHz
• Shielding: Shielded configuration

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Physical dimensions: Compatible with 0.260" L x 0.175" W footprint (±0.010" tolerance acceptable)
• Height seated maximum: 0.115" (2.92mm) with ±0.010" variance acceptable

Compliance Requirements:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant acceptable)
• Moisture sensitivity level: MSL 1 (Unlimited)
• ECCN classification: EAR99

The SRR6603-222ML from Bourns Inc. meets all substitution criteria with equivalent electrical performance and compatible mechanical specifications.

Engineering Selection Recommendations

Primary Part: UP0.4SC-222-R

The UP0.4SC-222-R maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. This part is suitable for applications requiring the UNI-PAC™ 0.4SC series specification or when Eaton component qualification is mandated.

Substitute Part: SRR6603-222ML

The SRR6603-222ML from Bourns Inc. is qualified as a direct substitute based on electrical and mechanical equivalence. This part offers:

• Identical inductance, current rating, and DC resistance specifications
• Matching Q factor and self resonant frequency performance
• Extended operating temperature range (-55°C to 125°C versus -40°C to 125°C)
• ROHS3 compliance status
• Ferrite drum core construction with equivalent shielding performance
• Compatible physical dimensions within manufacturing tolerance

Selection between these parts is determined by supply availability, cost considerations, and specific design qualification requirements. Both parts carry Active product status and meet all compliance certifications for general industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-222ML be used as a direct replacement for the UP0.4SC-222-R in existing designs?

A: Yes. The SRR6603-222ML meets all electrical and mechanical substitution criteria. Physical dimensions are compatible within standard manufacturing tolerances. Both parts are shielded, surface mount inductors with identical inductance, current rating, and DC resistance specifications. PCB layout modifications are not required.

Q: What is the difference in core material between these two parts?

A: The UP0.4SC-222-R uses a wirewound core construction. The SRR6603-222ML uses a ferrite drum core with wirewound configuration. Both achieve equivalent electrical performance at the specified operating frequency and current levels.

Q: Are there temperature range differences that affect substitution?

A: The SRR6603-222ML extends the lower operating temperature limit to -55°C compared to the UP0.4SC-222-R at -40°C. Both parts operate to 125°C maximum. This difference does not prevent substitution; the SRR6603-222ML is compatible with all applications qualified for the UP0.4SC-222-R temperature range.

Q: Do the physical dimension differences affect PCB placement?

A: No. The length and width dimensions are equivalent (0.260" x 0.175" versus 0.260" x 0.173"). Height seated maximum differs by 0.003" (0.115" versus 0.118"), which is within standard PCB clearance tolerances and does not require design modification.

Q: What is the significance of the RoHS compliance difference?

A: The UP0.4SC-222-R carries RoHS Compliant status. The SRR6603-222ML carries ROHS3 Compliant status. Both designations indicate compliance with hazardous substance restrictions. ROHS3 represents the current regulatory standard and is fully compatible with applications requiring RoHS compliance.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the UP0.4SC-222-R and SRR6603-222ML are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the MSL rating and why is it important?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints during storage and assembly.
