UP0.4SC-331-R Equivalent & Substitute Parts

Part Overview

The UP0.4SC-331-R is a 330 µH shielded wirewound inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 0.4SC series. This surface mount component is rated for 200 mA continuous current with a maximum DC resistance of 1.4Ohm and operates across the temperature range of -40°C to 125°C. The component is RoHS Compliant and carries an MSL rating of 1 (Unlimited), indicating minimal moisture sensitivity.

The product maintains Active status in the market. Identifying equivalent substitute parts becomes necessary when primary inventory is unavailable, when supply chain optimization is required, or when design flexibility permits component interchangeability within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP0.4SC-331-R is determined by strict alignment across the following critical parameters:

Electrical Parameters (Mandatory Match):

• Inductance value: 330 µH
• Inductance tolerance: ±20%
• Current rating: 200 mA minimum
• DC resistance: 1.4Ohm maximum
• Shielding requirement: Shielded configuration
• Q factor @ 100kHz: 40
• Self resonant frequency: 5 MHz

Mechanical Parameters (Mandatory Match):

• Mounting type: Surface Mount
• Physical footprint: 6.60mm × 4.45mm length and width
• Height seated maximum: 2.92mm
• Package classification: Nonstandard

Compliance & Environmental Parameters:

• Operating temperature range: -40°C to 125°C minimum
• RoHS compliance status
• MSL rating: 1 (Unlimited)

The SRR6603-331ML from Bourns Inc. qualifies as a direct substitute based on matching all electrical specifications, maintaining compatible physical dimensions within tolerance, and meeting or exceeding environmental and compliance requirements.

Engineering Selection Recommendations

Primary Part: UP0.4SC-331-R

The UP0.4SC-331-R maintains Active product status with confirmed inventory availability (615 pcs). This component is RoHS Compliant and carries EAR99 export classification. Selection of the primary part is appropriate when supply is available and existing design validation has been completed against this specific manufacturer's specifications.

Substitute Part: SRR6603-331ML

The SRR6603-331ML from Bourns Inc. qualifies as a direct electrical and mechanical substitute. This component demonstrates:

• Identical electrical performance across all specified parameters
• Compatible physical dimensions with negligible height variance (3.00mm vs. 2.92mm seated maximum)
• Extended lower operating temperature limit (-55°C vs. -40°C), providing broader environmental coverage
• ROHS3 Compliant status, meeting current regulatory requirements
• Higher inventory availability (2,736 pcs), supporting supply chain continuity
• Ferrite drum core construction with identical shielding and performance characteristics

Selection of the SRR6603-331ML is appropriate when primary inventory is constrained, when extended temperature range is beneficial, or when supply chain optimization favors Bourns component availability.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-331ML be used as a direct replacement for the UP0.4SC-331-R in existing designs?

A: Yes. Both components match across all critical electrical parameters (330 µH inductance, 200 mA rating, 1.4Ohm DCR, 40 Q @ 100kHz, 5 MHz self resonant frequency) and maintain compatible physical dimensions. The SRR6603-331ML height of 3.00mm seated maximum is within acceptable tolerance relative to the UP0.4SC-331-R specification of 2.92mm maximum.

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

A: The UP0.4SC-331-R uses a wirewound core construction. The SRR6603-331ML uses a ferrite drum core with wirewound configuration. Both achieve identical electrical performance specifications and shielding characteristics at the specified operating parameters.

Q: Are there temperature range differences that affect substitution?

A: The SRR6603-331ML operates across -55°C to 125°C, while the UP0.4SC-331-R operates across -40°C to 125°C. The substitute part provides extended lower temperature capability. For applications operating within the -40°C to 125°C range, both components are functionally equivalent.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the UP0.4SC-331-R and SRR6603-331ML carry MSL rating 1 (Unlimited), indicating minimal moisture sensitivity and identical handling requirements.

Q: Are the physical dimensions identical?

A: Dimensions are compatible but not identical. Length is 6.60mm for both. Width is 4.45mm (UP0.4SC-331-R) versus 4.40mm (SRR6603-331ML). Height seated maximum is 2.92mm (UP0.4SC-331-R) versus 3.00mm (SRR6603-331ML). These variations remain within acceptable PCB layout tolerances for surface mount placement.

Q: What is the compliance status of each part?

A: The UP0.4SC-331-R is RoHS Compliant. The SRR6603-331ML is ROHS3 Compliant, representing current regulatory alignment. Both carry EAR99 export classification and identical HTSUS coding (8504.50.4000).

Q: Which part should be selected for new designs?

A: Selection depends on supply availability and design requirements. For new designs, either component is acceptable based on electrical and mechanical equivalence. The SRR6603-331ML offers extended temperature range and higher current inventory availability.
