• Inductance tolerance: ±30% (identical)
• Shielding: Shielded (identical)
• Core material: Ferrite (identical)
• Mounting type: Surface Mount (identical)
• Inductance test frequency: 100 kHz (identical)
• RoHS3 compliance: Yes (identical)
• Moisture sensitivity level: 1 (Unlimited) (identical)

The substitute part maintains all critical electrical specifications required for functional equivalence in the target application.

Parameter Comparison

Engineering Selection Recommendations

The CDRH2D14NP-3R3NC is the qualified substitute for the obsolete ASPI-0320S-3R3N-T3. Selection is based on:

• Active product status ensuring ongoing availability and supply chain support
• Identical electrical specifications (inductance, current rating, DC resistance, tolerance)
• ROHS3 compliance matching the original part
• Equivalent moisture sensitivity classification
• Extended operating temperature range (-40°C ~ 100°C vs. -25°C ~ 100°C), providing broader environmental compatibility
• Saturation current specification of 1.2 A exceeds the original 1.1 A rating, offering improved margin

Physical dimensions differ slightly (3.00mm vs. 3.20mm footprint; 1.10mm vs. 2.00mm height). PCB layout verification is required to confirm mechanical fit within the target application's spatial constraints.

Frequently Asked Questions (FAQ)

Q: What makes CDRH2D14NP-3R3NC a valid substitute for ASPI-0320S-3R3N-T3?

A: Both parts share identical inductance (3.3 µH), current rating (1.24 A), DC resistance (125mOhm Max), tolerance (±30%), shielding type, core material, and mounting configuration. These parameters define functional equivalence for inductor selection.

Q: Are there physical compatibility concerns?

A: The substitute part has a smaller footprint (3.00mm vs. 3.20mm) and lower profile (1.10mm vs. 2.00mm). PCB layout must be reviewed to confirm the component fits within available space and clearance requirements.

Q: Does the substitute part meet compliance requirements?

A: Yes. CDRH2D14NP-3R3NC is ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's certifications.

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

A: The substitute part specifies 1.2 A saturation current versus 1.1 A for the original. This represents improved performance margin and does not restrict substitution.

Q: What is the operating temperature range difference?

A: CDRH2D14NP-3R3NC operates from -40°C to 100°C, compared to -25°C to 100°C for the original part. The extended lower temperature range provides additional environmental flexibility.

Q: Is packaging format a consideration?

A: The substitute is supplied in Tape & Reel (TR) format. Confirm compatibility with assembly equipment and procurement workflows.
