• Core type: Ferrite drum core, wirewound
• Shielding: Shielded construction
• Mounting: Surface mount

Secondary Compatibility Parameters:

• Current rating: minimum 23 A (equal or greater)
• DC resistance: maximum 1.14 mOhm (equal or lower)
• Saturation current: minimum 48 A (equal or greater)
• Operating temperature range: must encompass -40°C to 105°C
• RoHS compliance: ROHS3 Compliant

Substitute parts must satisfy all primary matching criteria and maintain compatibility within secondary parameters to ensure functional equivalence in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-7318-R20M-T from Abracon LLC is identified as a substitute part for the obsolete CDEP106NP-R20MC-50. Both components share identical inductance values, tolerance specifications, core material, shielding configuration, and mounting type.

Compliance and Certification Alignment: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility with the original specification.

Product Status Advantage: The ASPI-7318-R20M-T is classified as active product status, providing assured long-term availability and supply chain continuity compared to the obsolete CDEP106NP-R20MC-50.

Parameter Deviations: The ASPI-7318-R20M-T exhibits three parameter deviations from the original specification:

1. DC Resistance: 3 mOhm maximum versus 1.14 mOhm maximum (2.63× higher)
2. Saturation Current: 41 A versus 48 A (7 A lower)
3. Physical dimensions: 7.30mm × 6.80mm × 3.00mm versus 10.00mm × 10.00mm × 6.50mm (smaller package)

These deviations must be evaluated against circuit requirements. Applications with strict DC resistance or saturation current constraints may require alternative substitute candidates or circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-7318-R20M-T directly replace the CDEP106NP-R20MC-50 in all applications?

A: Direct substitution is possible only when circuit design tolerates the higher DC resistance (3 mOhm vs. 1.14 mOhm) and lower saturation current (41 A vs. 48 A). Applications sensitive to these parameters require circuit analysis or alternative substitute parts.

Q: What is the significance of the DC resistance difference?

A: The ASPI-7318-R20M-T exhibits 2.63 times higher DC resistance. In high-current applications, this increases resistive losses and heat generation. Power dissipation calculations must be performed to confirm thermal compatibility.

Q: Does the smaller package size of the ASPI-7318-R20M-T affect compatibility?

A: The ASPI-7318-R20M-T is physically smaller (7.30mm × 6.80mm × 3.00mm) compared to the CDEP106NP-R20MC-50 (10.00mm × 10.00mm × 6.50mm). PCB layout and mechanical clearance must be verified. The smaller footprint may provide design advantages in space-constrained applications.

Q: Why is the saturation current lower in the substitute part?

A: The ASPI-7318-R20M-T has a saturation current of 41 A versus 48 A in the original part. This indicates different core material characteristics or winding configuration. Applications operating near saturation limits require verification that 41 A saturation current remains acceptable.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDEP106NP-R20MC-50 and ASPI-7318-R20M-T are ROHS3 compliant, ensuring regulatory compatibility for applications subject to RoHS requirements.

Q: What is the advantage of the ASPI-7318-R20M-T regarding product status?

A: The ASPI-7318-R20M-T is classified as active product, ensuring ongoing manufacturing and supply availability. The CDEP106NP-R20MC-50 is obsolete, creating supply risk and potential discontinuation of inventory.
