Engineering Selection Recommendations
DC1390-224K Selection Criteria:
- Applications requiring full operating temperature range of -55°C to 125°C
- Designs where RoHS non-compliance is acceptable or not required
- Existing inventory or supply chain established with API Delevan Inc.
1140-221K-RC Selection Criteria:
- Applications operating within -55°C to 105°C temperature range
- Designs requiring ROHS3 compliance
- Applications benefiting from higher current saturation margin (14 A vs. 9.09 A)
- Higher continuous current rating (7.4 A vs. 6.9 A) provides additional design margin
- REACH unaffected status maintained
Both parts are active products with confirmed inventory availability. Selection between these components depends on specific compliance requirements and operating temperature constraints of the target application.
Frequently Asked Questions (FAQ)
Q: Can the 1140-221K-RC replace the DC1390-224K in all applications?
A: The 1140-221K-RC is electrically and mechanically equivalent for applications operating within the -55°C to 105°C temperature range. Applications requiring operation above 105°C must use the DC1390-224K, which is rated to 125°C.
Q: What is the significance of the higher current saturation rating in the 1140-221K-RC?
A: The 1140-221K-RC has a saturation current of 14 A compared to 9.09 A in the DC1390-224K. This provides additional margin before inductor saturation occurs, beneficial in circuits experiencing transient current spikes or design margin requirements.
Q: Are the physical dimensions compatible between these parts?
A: Both parts use radial, vertical cylinder packaging with similar dimensions. DC1390-224K diameter is 37.60 mm with height 27.03 mm; 1140-221K-RC diameter is 38.10 mm with height 26.16 mm. Verify PCB layout clearances for your specific application.
Q: What compliance differences exist between these parts?
A: The 1140-221K-RC is ROHS3 compliant, while the DC1390-224K is RoHS non-compliant. Both are REACH unaffected. Select based on your product's regulatory requirements.
Q: Are both parts available for immediate procurement?
A: Yes. DC1390-224K has 814 pieces in stock; 1140-221K-RC has 1269 pieces in stock, both listed as new original inventory.
Q: Do these inductors have identical DC resistance characteristics?
A: Yes. Both parts specify 50 mOhm maximum DC resistance, ensuring equivalent power dissipation and thermal performance in circuit applications.
