Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASPI-0312FSSA-220M-T4 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Inductance: 22 µH at 100 kHz test frequency
• Inductance Tolerance: ±20%
• Shielding: Shielded configuration
• Mounting Type: Surface Mount
• Physical Footprint: 3.00mm x 3.00mm base dimensions
• Core Type: Drum core, wirewound construction

Allowable Variation Parameters:

• Current Rating: Minimum 400 mA (higher ratings acceptable)
• DC Resistance: Up to 700mOhm (lower values preferred for efficiency)
• Operating Temperature: Must encompass -30°C to 100°C minimum
• Core Material: Ferrite or Nickel Zinc Ferrite acceptable
• Saturation Current: Minimum 430mA (higher values acceptable)

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

ASPI-0312FS-220M-T2 (Abracon LLC): This substitute is the primary equivalent for direct replacement. It maintains identical inductance, tolerance, and physical footprint while offering improved DC resistance (630mOhm vs. 700mOhm) and higher current rating (420 mA vs. 400 mA). Product status is active with ROHS3 compliance confirmed. Operating temperature range extends to 120°C, providing broader thermal coverage. Packaging is available in Tape & Reel format. Height remains at 1.20mm maximum, ensuring PCB layout compatibility.

CDRH2D18B/HPNP-220MC (Sumida America Components Inc.): This substitute provides equivalent electrical performance with the highest current rating (450 mA) and saturation current (580mA) among all options. DC resistance is comparable at 658mOhm maximum. Operating temperature range extends to -40°C, providing superior low-temperature performance. Product status is active. Physical footprint matches at 3.00mm x 3.00mm; however, maximum seated height is 1.95mm, which exceeds the original 1.20mm specification. This height difference requires PCB layout verification before selection. Packaging is Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0312FS-220M-T2 be used as a direct drop-in replacement? A: Yes. The ASPI-0312FS-220M-T2 maintains identical inductance (22 µH), tolerance (±20%), physical footprint (3.00mm x 3.00mm), and maximum height (1.20mm). All electrical parameters are within acceptable substitution ranges. Active product status ensures ongoing availability.

Q: What is the key difference between the two substitute parts? A: ASPI-0312FS-220M-T2 is the closest electrical and mechanical match from Abracon LLC. CDRH2D18B/HPNP-220MC offers higher current and saturation ratings but has a taller profile (1.95mm vs. 1.20mm), requiring PCB layout verification.

Q: Does the height difference of CDRH2D18B/HPNP-220MC affect compatibility? A: The 0.75mm additional height (1.95mm vs. 1.20mm) may impact PCB clearance, component spacing, or enclosure fit. Physical layout review is required before selection.

Q: Are both substitutes RoHS3 compliant? A: ASPI-0312FS-220M-T2 is confirmed ROHS3 compliant. CDRH2D18B/HPNP-220MC compliance status is not specified in available data.

Q: What is the impact of lower saturation current in ASPI-0312FS-220M-T2? A: The saturation current of 370mA is lower than the original 430mA specification. In applications where current approaches saturation limits, this may affect inductor performance. Verify circuit current profiles against this specification.

Q: Can these parts be used interchangeably in the same circuit? A: Both parts meet the core electrical requirements (22 µH inductance, ±20% tolerance, shielded configuration). However, differences in saturation current, DC resistance, and physical height require circuit-level validation before interchangeable use.

Q: What packaging formats are available? A: The original part used nonstandard packaging. Both substitutes are available in Tape & Reel (TR) format, which is standard for surface mount production environments.
