Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IDCS7328ER102M are qualified based on the following critical parameters: inductance value of 1 mH, ferrite drum core construction with shielding, surface mount configuration, and ROHS3 compliance. The substitution logic accommodates variations in current rating (within operational design margins), DC resistance (within acceptable circuit performance limits), and operating temperature range (minimum -40°C to 125°C or higher). All substitute parts maintain the same inductance tolerance of ±20% and are packaged in Tape & Reel format for automated assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. The ASPI-1306S-102M-T from Abracon LLC provides direct electrical equivalence with identical current rating and DC resistance specifications; however, the operating temperature maximum is limited to 85°C, which restricts use in applications requiring the full -40°C to 125°C range.

The SRR1208-102KL from Bourns Inc. offers superior DC resistance at 1.65 Ohm maximum and tighter inductance tolerance of ±10%, with full temperature range support. Current rating is reduced to 500 mA, which may require circuit evaluation for applications operating near the 530 mA specification.

The SRR1806-102M from Bourns Inc. maintains full temperature range operation and higher saturation current of 900 mA. Current rating is 450 mA with DC resistance of 2.16 Ohm, requiring assessment for circuits dependent on lower resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can SRR1208-102KL be used as a direct replacement for IDCS7328ER102M?

A: The SRR1208-102KL is electrically compatible for applications where the 500 mA current rating is sufficient. The lower DC resistance of 1.65 Ohm provides improved efficiency. Verify that circuit design does not depend on the additional 30 mA current margin provided by the original part.

Q: What is the impact of the ASPI-1306S-102M-T operating temperature limit of 85°C?

A: The ASPI-1306S-102M-T is suitable only for applications where the maximum ambient temperature does not exceed 85°C. Applications requiring operation at temperatures between 85°C and 125°C must use IDCS7328ER102M, SRR1208-102KL, or SRR1806-102M.

Q: Are all substitute parts available in the same package configuration?

A: All substitute parts are supplied in Tape & Reel (TR) packaging for surface mount assembly. Physical dimensions vary slightly between manufacturers; verify PCB footprint compatibility before design implementation.

Q: Which substitute part offers the best DC resistance performance?

A: The SRR1208-102KL provides the lowest maximum DC resistance at 1.65 Ohm, compared to 2.01 Ohm for the original part and 2.16 Ohm for the SRR1806-102M. Lower DC resistance reduces power dissipation in current-limited applications.

Q: Can inductance tolerance differences affect circuit performance?

A: The SRR1208-102KL offers ±10% tolerance compared to ±20% for other parts. Tighter tolerance may improve circuit stability in applications sensitive to inductance variation. Verify that circuit design margins accommodate the ±20% tolerance of other substitute options.
