Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IDCS7328ER220M are qualified based on the following critical parameters: inductance value (22 µH), inductance tolerance (±20%), current rating capability (minimum 3.1 A), DC resistance (59 mOhm maximum), core material (ferrite), shielding type (shielded), and mounting configuration (surface mount). All substitute parts maintain ferrite drum core construction with identical inductance specifications and equivalent current handling characteristics. Substitution is valid when the alternative part meets or exceeds the electrical performance envelope of the original component while maintaining mechanical compatibility with the PCB footprint and assembly process.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance equivalent to the IDCS7328ER220M. The ASPI-1306S-220M-T from Abracon LLC provides direct electrical equivalence with identical current rating and DC resistance specifications; however, the operating temperature range is limited to -40°C to 85°C, which restricts use in applications requiring the full -40°C to 125°C envelope. The SRR1208-220ML from Bourns Inc. offers superior DC resistance performance at 43 mOhm maximum and higher current rating of 4.6 A, with full temperature range support; physical dimensions are smaller (12.70mm x 12.70mm versus 18.54mm x 15.24mm), requiring PCB layout verification. The SRR1806-220M from Bourns Inc. maintains full temperature range capability and saturation current of 6.2 A with DC resistance of 53 mOhm, with physical dimensions closely matching the original part (18.30mm x 14.00mm).

Frequently Asked Questions (FAQ)

Q: Can ASPI-1306S-220M-T replace IDCS7328ER220M in all applications? A: The ASPI-1306S-220M-T is electrically equivalent for inductance, current rating, and DC resistance. Substitution is valid only for applications operating within the -40°C to 85°C temperature range. Applications requiring operation above 85°C must use SRR1208-220ML or SRR1806-220M.

Q: What are the physical footprint differences between substitute parts? A: The SRR1208-220ML has a smaller footprint (12.70mm x 12.70mm) compared to the original IDCS7328ER220M (18.54mm x 15.24mm). The SRR1806-220M footprint (18.30mm x 14.00mm) is similar to the original. PCB layout compatibility must be verified before substitution.

Q: Which substitute part offers the best DC resistance performance? A: The SRR1208-220ML provides the lowest DC resistance at 43 mOhm maximum, compared to 59 mOhm for the original part and ASPI-1306S-220M-T, and 53 mOhm for the SRR1806-220M.

Q: Are all substitute parts available in the same packaging format? A: The IDCS7328ER220M and ASPI-1306S-220M-T are supplied in Tape & Reel (TR) packaging. The SRR1208-220ML is available in Cut Tape (CT) & Digi-Reel® format. The SRR1806-220M is supplied in Tape & Reel (TR) packaging. Packaging format may affect procurement and assembly processes.

Q: What is the saturation current difference between the original and substitute parts? A: The IDCS7328ER220M, ASPI-1306S-220M-T, and SRR1806-220M all have saturation currents of 6 A or higher. The SRR1208-220ML has a lower saturation current of 4 A, which may limit performance in high-current transient conditions.
