Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD7030-180-R are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value within ±30% tolerance band (17.3 µH nominal allows 12.1 µH to 22.5 µH range)
• Current rating equal to or greater than 1.7 A
• DC resistance (DCR) at or below 95 mOhm maximum
• Ferrite core material with shielding
• Surface mount package configuration
• Operating temperature range covering -40°C to 125°C minimum
• RoHS compliance status
• Inductance test frequency at 100 kHz

Identified Substitute Parts:

• CDRH6D28NP-180NC (Sumida America Components Inc.)
• CDRH6D38NP-180NC (Sumida America Components Inc.)

Both substitute parts meet the core electrical requirements within the specified tolerance band and are qualified for direct substitution in applications where the SD7030-180-R is specified.

Parameter Comparison

Engineering Selection Recommendations

SD7030-180-R (Primary Component): The SD7030-180-R remains the specified component with active production status. It provides the highest current rating at 1.7 A and supports the full operating temperature range to 125°C. RoHS compliance is confirmed. This part is suitable for applications requiring maximum thermal headroom and current capacity within the 17.3 µH inductance specification.

CDRH6D38NP-180NC (Preferred Substitute): This Sumida component offers the closest electrical match with 18 µH inductance, 1.5 A current rating, and 92 mOhm DCR. ROHS3 compliance is confirmed. The 4.00 mm seated height is 1.00 mm greater than the primary part; PCB layout accommodation is required. Operating temperature range extends to 100°C, which is suitable for applications not requiring the full 125°C upper limit of the primary component.

CDRH6D28NP-180NC (Secondary Substitute): This Sumida component provides 18 µH inductance with 1.32 A current rating and 95 mOhm DCR. ROHS3 compliance is confirmed. The current rating is lower than both the primary part and the CDRH6D38NP-180NC variant. This part is suitable only for applications where the maximum current requirement does not exceed 1.32 A. Operating temperature range extends to 100°C.

Compliance Considerations: All three parts carry EAR99 ECCN classification and are RoHS compliant. The substitute parts carry ROHS3 certification, which represents an enhanced compliance standard. MSL 1 rating is consistent across all parts, indicating unlimited moisture sensitivity protection suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can CDRH6D28NP-180NC replace SD7030-180-R in all applications?

A: No. The CDRH6D28NP-180NC has a maximum current rating of 1.32 A, which is lower than the SD7030-180-R rating of 1.7 A. This part is suitable only for applications where the circuit current does not exceed 1.32 A. Verify the actual circuit current requirement before substitution.

Q: What is the inductance difference between the main part and substitutes?

A: The SD7030-180-R is rated at 17.3 µH, while both Sumida substitutes are rated at 18 µH. The difference of 0.7 µH falls within the ±30% tolerance band specified for all three parts. This variation is acceptable for most filter and impedance matching applications operating at 100 kHz test frequency.

Q: Are there physical size differences that affect PCB layout?

A: Yes. The SD7030-180-R measures 7.00 x 7.00 mm with 3.00 mm seated height. Both Sumida substitutes measure 6.70 x 6.70 mm footprint. The CDRH6D38NP-180NC has 4.00 mm seated height (1.00 mm taller), while the CDRH6D28NP-180NC matches the 3.00 mm height. Verify PCB clearance and component placement before substituting the taller variant.

Q: What is the temperature operating range difference?

A: The SD7030-180-R operates from -40°C to 125°C. Both Sumida substitutes operate from -40°C to 100°C. The primary part provides 25°C additional upper temperature margin. For applications requiring operation above 100°C, the SD7030-180-R is the only qualified option among these three parts.

Q: Are all three parts RoHS compliant?

A: Yes. The SD7030-180-R carries RoHS Compliant certification. Both Sumida substitutes carry ROHS3 Compliant certification, which represents an enhanced compliance standard. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the DC resistance (DCR) difference?

A: The SD7030-180-R and CDRH6D28NP-180NC both specify 95 mOhm maximum DCR. The CDRH6D38NP-180NC specifies 92 mOhm maximum DCR, which is 3 mOhm lower. Lower DCR reduces resistive losses in the inductor. All three values are within acceptable range for typical power supply and filtering applications.

Q: Can I use CDRH6D38NP-180NC as a direct drop-in replacement?

A: The CDRH6D38NP-180NC is electrically compatible for applications where circuit current does not exceed 1.5 A and operating temperature does not exceed 100°C. Physical compatibility requires verification: the 4.00 mm seated height is 1.00 mm taller than the primary part. Confirm PCB layout clearance and component placement before substitution.

Q: What packaging format is used for all three parts?

A: All three parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Reel specifications and tape pitch should be verified with the supplier for compatibility with existing pick-and-place equipment.
