SD7030-150-R Equivalent & Substitute Parts

Part Overview

The SD7030-150-R is a fixed surface mount inductor manufactured by Eaton - Electronics Division. This shielded drum core, wirewound inductor is rated for 1.7 A with an inductance value of 14.6 µH and a maximum DC resistance of 84 mOhm. The component operates across the temperature range of -40°C to 125°C and is RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

The SD7030-150-R maintains Active product status. Substitute parts are identified based on matching or compatible electrical specifications, mechanical dimensions, and environmental ratings to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD7030-150-R are identified based on the following electrical and mechanical compatibility criteria:

Inductance Value: The substitute must fall within the tolerance band of the primary specification. The SD7030-150-R specifies 14.6 µH ±30%, establishing an acceptable range of 10.22 µH to 18.98 µH at the 100 kHz test frequency.

Current Rating: The substitute current rating must support the application's maximum current demand. The SD7030-150-R is rated for 1.7 A continuous current.

DC Resistance: Maximum DCR of 84 mOhm ensures equivalent power dissipation and thermal performance. Substitutes with equal or lower DCR maintain or improve efficiency.

Saturation Current: The Isat specification defines the current level at which inductance begins to degrade. Substitutes must provide adequate margin above the application's peak current.

Shielding: Both the main part and substitutes must be shielded to maintain electromagnetic containment in the circuit environment.

Operating Temperature Range: The substitute must support the full operating temperature envelope of the application. The SD7030-150-R operates from -40°C to 125°C.

Mounting and Package: Surface mount technology and nonstandard package dimensions (7.00 × 7.00 × 3.00 mm) must be preserved for PCB compatibility.

Regulatory Compliance: RoHS compliance status must be maintained or upgraded.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (SD7030-150-R): Select this Eaton component when the application requires the full 1.7 A current rating and operating temperature range extending to 125°C. The part maintains Active product status with established supply availability (956 pcs in stock). RoHS compliance is confirmed.

Substitute Part (CDRH6D28NP-150NC): The Sumida CDRH6D28NP-150NC is suitable as a substitute when the application current requirement does not exceed 1.4 A and the maximum operating temperature does not exceed 100°C. The substitute provides equivalent DC resistance (84 mOhm max) and shielding characteristics. ROHS3 compliance exceeds the primary part's RoHS status. Substitute availability is higher (1,788 pcs in stock).

Mechanical Consideration: The Sumida substitute has a slightly smaller footprint (6.70 × 6.70 mm versus 7.00 × 7.00 mm). Verify PCB layout and component placement clearances before substitution. The 3.00 mm height is identical for both parts.

Compliance: Both parts meet regulatory requirements for RoHS compliance. The Sumida part's ROHS3 status represents compliance with the updated directive.

Frequently Asked Questions (FAQ)

Q: Can the CDRH6D28NP-150NC replace the SD7030-150-R in all applications?

A: No. The Sumida substitute is limited to applications where the maximum current does not exceed 1.4 A and the maximum operating temperature does not exceed 100°C. The primary Eaton part supports 1.7 A and temperatures to 125°C. Verify your application's current and temperature requirements before substitution.

Q: Are the inductance values interchangeable?

A: Yes, within the specified tolerance band. The SD7030-150-R specifies 14.6 µH ±30% and the CDRH6D28NP-150NC specifies 15 µH ±30%. Both values fall within acceptable tolerance ranges for equivalent circuit performance at the 100 kHz test frequency.

Q: What is the impact of the different package dimensions?

A: The Sumida part is 0.3 mm smaller in length and width (6.70 × 6.70 mm versus 7.00 × 7.00 mm). The height remains 3.00 mm for both parts. Verify that your PCB layout accommodates the smaller footprint. The substitute may fit in the same general area but requires confirmation of specific placement constraints and clearances.

Q: Does the DC resistance difference affect performance?

A: No. Both parts specify a maximum DC resistance of 84 mOhm. Equivalent DCR ensures identical power dissipation and thermal performance in the circuit.

Q: Is shielding maintained in the substitute?

A: Yes. Both the SD7030-150-R and CDRH6D28NP-150NC are shielded components. Electromagnetic containment characteristics are preserved in the substitute.

Q: What is the significance of the saturation current specification?

A: The saturation current (Isat) indicates the point at which the inductor's inductance begins to degrade. The SD7030-150-R specifies Isat at 1.4 A. The Sumida substitute does not provide an explicit Isat specification. Ensure your application's peak current remains below the rated current limit of 1.4 A for the substitute.

Q: Are both parts RoHS compliant?

A: Yes. The SD7030-150-R is RoHS compliant. The CDRH6D28NP-150NC is ROHS3 compliant, which represents compliance with the updated RoHS directive and is acceptable for applications requiring RoHS certification.

Q: What is the moisture sensitivity rating, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating. This indicates minimal moisture sensitivity and no special storage or handling precautions are required during normal manufacturing and assembly processes.
