CDRH6D38-220NC Equivalent & Substitute Parts

Part Overview

The CDRH6D38-220NC is a 22 µH shielded surface mount inductor manufactured by Sumida America Components Inc., rated for 1.3 A with a maximum DC resistance of 96 mOhm. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The part operates across the temperature range of -40°C to 100°C and is tested at 100 kHz inductance frequency. Due to its obsolete status, direct substitutes with active product availability are required for new designs and production applications.

Current rating of 1.3 A (minimum requirement)
Shielded construction (electromagnetic containment requirement)
Surface mount mounting type (assembly process compatibility)
DC resistance within acceptable operational limits

Compatible Parameter Ranges:

Inductance tolerance of ±20% or tighter (±30% or better)
Operating temperature range that encompasses or exceeds -40°C to 100°C
Package dimensions that accommodate PCB footprint constraints
Nonstandard package classification with compatible physical dimensions

Acceptable Variations:

DC resistance lower than 96 mOhm maximum (improved performance)
Higher current saturation ratings (enhanced capability)

Engineering Selection Recommendations

CDRH6D38NP-220NC (Direct Substitute - Recommended Primary Choice)

The CDRH6D38NP-220NC is the optimal substitute for the obsolete CDRH6D38-220NC. Both parts are manufactured by Sumida America Components Inc. and share identical electrical specifications: 22 µH inductance, 1.3 A current rating, 96 mOhm maximum DC resistance, and -40°C to 100°C operating temperature range. Physical dimensions and mounting characteristics are identical (6.70 x 6.70 mm footprint, 4.00 mm maximum seated height). The CDRH6D38NP-220NC maintains active product status with significantly higher inventory availability (9545 pieces versus 3018 pieces). The part achieves ROHS3 compliance, providing regulatory advantage for new designs. Packaging is available in Cut Tape and Digi-Reel formats, supporting both prototype and production workflows. This part provides direct functional and physical compatibility with zero design modification requirements.

PF0465.223NLT (Similar Substitute - Secondary Option)

The PF0465.223NLT manufactured by Pulse Electronics meets all critical electrical parameters: 22 µH inductance, 1.3 A current rating, and shielded surface mount construction. This part offers improved DC resistance performance at 86 mOhm maximum (10 mOhm lower than the main part), reducing power dissipation. Inductance tolerance is tighter at ±20% compared to ±30%. Operating temperature range extends to 125°C, exceeding the original specification. The part achieves ROHS3 compliance and REACH Unaffected status. Physical dimensions differ: 7.20 x 7.20 mm footprint with 5.20 mm maximum seated height. These dimensional differences require PCB layout verification to confirm clearance compatibility. Inventory availability is lower at 862 pieces. This part is suitable when PCB layout accommodates the larger footprint and when extended temperature performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can CDRH6D38NP-220NC be used as a direct replacement for CDRH6D38-220NC without PCB modifications?

A: Yes. The CDRH6D38NP-220NC is a direct substitute with identical electrical specifications and physical dimensions. No PCB layout modifications are required. Both parts share the same 6.70 x 6.70 mm footprint and 4.00 mm maximum seated height.
