UP2-330-R Equivalent & Substitute Parts

Part Overview

The UP2-330-R is a 33 µH unshielded wirewound inductor manufactured by Eaton - Electronics Division, part of the UNI-PAC™ 2 series. This surface mount component is rated for 2.4 A continuous current with a maximum DC resistance of 98.9mOhm and operates at 100 kHz test frequency. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original UP2-330-R becomes unavailable, when alternative packaging formats are required, or when design specifications allow for components with equivalent electrical characteristics from different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP2-330-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 33 µH (fixed)
• Inductance tolerance: ±20% (fixed)
• Mounting type: Surface Mount (fixed)
• Test frequency: 100 kHz (fixed)

Secondary Compatibility Criteria:

• Current rating: Minimum 2.4 A (substitute must meet or exceed)
• DC resistance: Maximum 98.9mOhm (substitute must not exceed)
• Saturation current: Minimum 1.7 A (substitute must meet or exceed)
• RoHS compliance: Required for equivalent substitution
• MSL rating: 1 (Unlimited) preferred for compatibility

Variable Parameters Allowing Substitution:

• Shielding type (shielded or unshielded acceptable based on circuit requirements)
• Core material (ferrite or standard acceptable)
• Packaging format (Tape & Reel or Bulk acceptable)
• Physical dimensions (nonstandard packages acceptable if mounting compatible)
• Operating temperature range (extended ranges acceptable)

All three substitute parts meet the primary matching criteria and maintain RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

ASPI-104S-330M-T (Abracon LLC)

This substitute is suitable for applications where shielded construction is required or preferred. The part meets all primary matching criteria with 33 µH inductance and ±20% tolerance. Current rating of 2.2 A is below the original 2.4 A specification; this part is appropriate only for circuits operating at or below 2.2 A continuous current. DC resistance of 93mOhm is superior to the original 98.9mOhm specification. ROHS3 compliance and MSL 1 rating ensure compatibility with standard manufacturing processes. Tape & Reel packaging matches the original format.

AX97-30330 (Triad Magnetics)

This substitute provides the highest current rating at 2.5 A, exceeding the original 2.4 A specification. The 33 µH inductance and ±20% tolerance match the original part. DC resistance of 110mOhm exceeds the original maximum of 98.9mOhm; this part is suitable only for applications where the higher resistance is acceptable. ROHS3 compliance is confirmed. Bulk packaging differs from the original Tape & Reel format. Operating temperature range of -40°C to 85°C is specified.

B82476B1333M100 (EPCOS - TDK Electronics)

This substitute offers the lowest DC resistance at 88mOhm, providing superior electrical performance compared to the original 98.9mOhm specification. Current rating of 2.3 A is below the original 2.4 A specification; this part is appropriate for circuits operating at or below 2.3 A continuous current. The 33 µH inductance and ±20% tolerance match the original part. ROHS3 compliance is confirmed. Extended operating temperature range of -55°C to 150°C provides broader thermal capability. AEC-Q200 automotive qualification is included. Tape & Reel packaging matches the original format.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-104S-330M-T replace the UP2-330-R in all applications?

A: The ASPI-104S-330M-T is suitable for applications operating at 2.2 A or below. If your circuit requires the full 2.4 A rating of the original part, this substitute is not appropriate. The shielded construction of the ASPI-104S-330M-T may provide benefits in noise-sensitive circuits but is not required for direct electrical equivalence.

Q: What is the significance of the DC resistance difference between these parts?

A: DC resistance directly affects power dissipation and voltage drop across the inductor. The B82476B1333M100 at 88mOhm produces the least heat, while the AX97-30330 at 110mOhm produces the most. Selection depends on thermal budget and efficiency requirements of the specific application.

Q: Does the shielding difference between parts affect substitution?

A: Shielding affects electromagnetic field containment and susceptibility to external interference. The unshielded UP2-330-R, AX97-30330, and B82476B1333M100 are electrically equivalent in this parameter. The shielded ASPI-104S-330M-T provides additional EMI containment but is not required for direct substitution unless circuit design specifically requires shielding.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original UP2-330-R is RoHS Compliant, and all three substitute parts are ROHS3 Compliant, confirming compliance with current RoHS regulations.

Q: What packaging formats are available?

A: The UP2-330-R, ASPI-104S-330M-T, and B82476B1333M100 are supplied in Tape & Reel format suitable for automated assembly. The AX97-30330 is supplied in Bulk format, requiring manual handling or alternative packaging for automated processes.

Q: Which substitute has the best thermal performance?

A: The B82476B1333M100 operates across the widest temperature range (-55°C to 150°C) and includes AEC-Q200 automotive qualification, indicating validated performance under demanding thermal conditions. The ASPI-104S-330M-T and AX97-30330 operate from -40°C to 85°C.

Q: Can I use the AX97-30330 if my circuit requires 2.4 A continuous current?

A: The AX97-30330 is rated for 2.5 A continuous current, which exceeds the 2.4 A requirement. This part is suitable for your application. However, verify that the higher DC resistance of 110mOhm (compared to the original 98.9mOhm) is acceptable for your thermal and efficiency specifications.
