Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SD7030-3R3-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 3.3 µH (within ±30% tolerance specification)
• Core type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration
• Mounting: Surface mount, nonstandard package
• Operating temperature range: -40°C ~ 125°C minimum

Secondary Compatibility Factors:

• Current rating: Substitute must support application current requirements
• DC resistance: Must be acceptable for circuit performance
• Package dimensions: Physical footprint compatibility
• Compliance certifications: RoHS and REACH status

The PA4301.332NLT from Pulse Electronics meets the primary matching criteria with identical inductance, core material, shielding, and operating temperature range. Substitution is valid when the application current requirement does not exceed 2.8 A and the slightly higher DC resistance (29.9 mOhm vs. 24 mOhm) is acceptable for the circuit design.

Parameter Comparison

Engineering Selection Recommendations

SD7030-3R3-R Selection Criteria:

• Applications requiring 3.7 A current rating
• Designs where 24 mOhm DCR specification is mandatory
• Original equipment manufacturer (OEM) specifications calling for Eaton components
• RoHS Compliant requirement with standard compliance pathway

PA4301.332NLT Selection Criteria:

• Applications with maximum current requirement of 2.8 A or less
• Designs where 29.9 mOhm DCR is acceptable for circuit operation
• ROHS3 Compliant requirement for enhanced regulatory alignment
• Pulse Electronics component preference or supply chain optimization

Both parts maintain identical inductance values, ferrite core construction, shielding configuration, and operating temperature range. Selection between these components is determined by current rating requirements and acceptable DC resistance limits for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can PA4301.332NLT replace SD7030-3R3-R in all applications?

A: No. The PA4301.332NLT has a lower current rating (2.8 A vs. 3.7 A) and higher DC resistance (29.9 mOhm vs. 24 mOhm). Substitution is valid only when the application current does not exceed 2.8 A and the increased DCR does not degrade circuit performance.

Q: Are the physical dimensions compatible?

A: The components have similar but not identical dimensions. SD7030-3R3-R measures 7.00mm x 7.00mm, while PA4301.332NLT measures 7.20mm x 7.20mm. Both have 3.00mm maximum height. PCB layout verification is required before substitution.

Q: What is the significance of the ±30% inductance tolerance?

A: The ±30% tolerance indicates the acceptable range of inductance variation from the nominal 3.3 µH value. Both parts share this tolerance specification, ensuring equivalent inductance consistency in circuit applications.

Q: Are both parts RoHS compliant?

A: Yes. SD7030-3R3-R is RoHS Compliant, and PA4301.332NLT is ROHS3 Compliant. Both meet RoHS requirements and are REACH Unaffected, suitable for regulated electronic assemblies.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in high-current applications?

A: No. The SD7030-3R3-R is rated for 3.7 A, while PA4301.332NLT is rated for 2.8 A. For applications exceeding 2.8 A, only the SD7030-3R3-R meets the current requirement specification.
