Substitute Part Grouping Explanation

Substitute parts for the ELL-4GG150M are selected based on the following critical parameters:

Inductance Value: Must be 15 µH with ±20% tolerance
Inductance Test Frequency: Must be measured at 100 kHz
Mounting Type: Surface mount only
Current Handling: Minimum continuous current rating of 580 mA
DC Resistance: Maximum 500 mOhm to maintain electrical performance
Compliance: ROHS3 compliant, MSL 1 rating
Physical Compatibility: Nonstandard package with similar footprint dimensions (3.80mm x 3.80mm base)

Two active substitute parts meet these criteria: ASPI-4030S-150M-T (Abracon LLC) and CDH38D11SLDNP-150MC (Sumida America Components Inc.).

Engineering Selection Recommendations

ASPI-4030S-150M-T (Abracon LLC) is the primary substitute for the ELL-4GG150M. This part exceeds the current rating requirement (1.11 A vs. 580 mA), features lower DC resistance (190 mOhm vs. 500 mOhm), and maintains shielding characteristics. The part is active in production with ROHS3 compliance and unlimited MSL rating. The increased height (3.00 mm vs. 1.40 mm) and slightly larger footprint (4.00mm x 4.00mm vs. 3.80mm x 3.80mm) must be evaluated for PCB layout compatibility. The specified operating temperature range (-40°C ~ 125°C) and self-resonant frequency (16 MHz) provide additional performance margin.

CDH38D11SLDNP-150MC (Sumida America Components Inc.) is an alternative substitute with identical footprint dimensions (3.80mm x 3.80mm) and lower height (1.20 mm vs. 1.40 mm). This part meets the current rating requirement (670 mA vs. 580 mA) and maintains DC resistance within specification (490 mOhm Max vs. 500 mOhm). However, this part is unshielded, which may introduce electromagnetic interference considerations in noise-sensitive applications. The part is active in production with ROHS3 compliance and unlimited MSL rating. Operating temperature range is -40°C ~ 105°C.

Both substitutes are ROHS3 compliant with MSL 1 ratings, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can ASPI-4030S-150M-T be used as a direct replacement for ELL-4GG150M?

A: ASPI-4030S-150M-T meets all electrical specifications and exceeds current handling capability. The primary consideration is physical compatibility: the part is 1.60 mm taller (3.00 mm vs. 1.40 mm) and has a slightly larger footprint (4.00mm x 4.00mm vs. 3.80mm x 3.80mm). PCB layout must accommodate these dimensional differences.

Q: What is the key difference between the two substitute parts?

A: ASPI-4030S-150M-T is shielded with superior current handling (1.11 A) and lower DC resistance (190 mOhm). CDH38D11SLDNP-150MC is unshielded but maintains the original footprint dimensions and lower profile height (1.20 mm). Shielding selection depends on electromagnetic interference requirements in the application.

Q: Are both substitute parts available in production quantities?

A: Yes. ASPI-4030S-150M-T has 36,136 pieces in stock. CDH38D11SLDNP-150MC has 1,122 pieces in stock. Both are active products from their respective manufacturers.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both ASPI-4030S-150M-T and CDH38D11SLDNP-150MC are ROHS3 compliant with MSL 1 (Unlimited) ratings, matching the original ELL-4GG150M specifications.

Q: What is the impact of lower DC resistance in ASPI-4030S-150M-T?

A: Lower DC resistance (190 mOhm vs. 500 mOhm) reduces resistive losses and heat generation during operation. This improves efficiency and thermal performance, particularly in high-current applications.

Q: Should shielding be a factor in selecting between the two substitutes?

A: Shielding is critical in applications with sensitive analog circuits, high-frequency signals, or noise-sensitive measurements. ASPI-4030S-150M-T maintains shielding characteristics of the original part. CDH38D11SLDNP-150MC is unshielded and may require additional circuit-level filtering or layout considerations to manage electromagnetic emissions.
