Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1008HC-223EKFS are identified based on the following critical electrical and mechanical parameters:

Inductance Value: 22 µH nominal with ±10% tolerance band Package Form Factor: 1008 (2520 Metric) surface mount configuration Core Type: Ferrite drum core, unshielded construction Current Handling: Minimum 200 mA continuous rating requirement DC Resistance: Maximum allowable DCR of 2.8Ω for thermal and efficiency constraints Environmental Compliance: ROHS3 compliance and operating temperature range compatibility

The NLCV25T-220K-EF from TDK Corporation meets these substitution criteria within the defined electrical and mechanical parameter space.

Parameter Comparison

Engineering Selection Recommendations

Supply Availability: The NLCV25T-220K-EF is actively produced by TDK Corporation with 33,100 pieces in current inventory, compared to the obsolete 1008HC-223EKFS status. This ensures long-term component availability for ongoing production and field service requirements.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent deployment.

Thermal Operating Range: The NLCV25T-220K-EF extends the upper operating temperature limit to 105°C versus 85°C for the original part, providing enhanced thermal margin in applications subject to elevated ambient or self-heating conditions.

Current Rating Consideration: The substitute part is rated for 160 mA continuous current, which is lower than the original 200 mA specification. Circuit designs operating at or near 200 mA maximum current require thermal analysis to confirm the substitute part operates within acceptable temperature rise limits.

DC Resistance Impact: The substitute exhibits 3.64Ω maximum DCR compared to 2.8Ω for the original part. This 30% increase in series resistance results in proportionally higher resistive losses and heat dissipation. Power budget calculations must account for this parameter difference in current-limited or efficiency-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the NLCV25T-220K-EF directly replace the 1008HC-223EKFS in existing designs?

A: Direct mechanical and electrical substitution is possible for applications operating below 160 mA continuous current. The identical inductance value, tolerance, package form factor, and core material ensure functional compatibility. However, the higher DC resistance and lower current rating require circuit-level validation before deployment.

Q: What is the impact of the 0.84Ω increase in DC resistance?

A: At 160 mA operating current, the additional resistance generates approximately 93 mW additional power dissipation compared to the original part. Thermal analysis of the PCB layout and ambient conditions is required to confirm acceptable junction temperature rise.

Q: Are the physical dimensions compatible for PCB assembly?

A: Both components use the 1008 (2520 Metric) package. The NLCV25T-220K-EF has slightly smaller physical dimensions (2.50mm × 2.00mm × 1.90mm height) compared to the 1008HC-223EKFS (2.92mm × 2.79mm × 2.10mm height). PCB footprints designed for the original part will accommodate the substitute with clearance margin.

Q: What is the significance of the higher Q factor in the substitute part?

A: The NLCV25T-220K-EF exhibits Q of 30 at 2.52 MHz versus 20 for the original part. Higher Q indicates lower losses at the test frequency, which may provide improved performance in RF filtering or resonant circuit applications. Both parts share identical self-resonant frequency of 18 MHz.

Q: Is the extended temperature range of the substitute part beneficial?

A: The NLCV25T-220K-EF operates to 105°C versus 85°C for the original part. This extended range provides additional thermal margin and may eliminate thermal derating requirements in applications subject to elevated ambient temperatures or self-heating conditions.

Q: What packaging format is available for the substitute part?

A: The NLCV25T-220K-EF is supplied in Tape & Reel (TR) format, identical to the original component, ensuring compatibility with automated assembly equipment and supply chain handling procedures.
