CDRH62NP-221MC Equivalent & Substitute Parts

Part Overview

The CDRH62NP-221MC is a 220 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 230 mA continuous current with a maximum DC resistance of 3.69 Ohm and operates across the temperature range of -40°C to 100°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain the same inductance value, tolerance, mounting type, and physical dimensions while meeting or exceeding the electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDRH62NP-221MC are identified based on strict equivalence of the following parameters:

Critical Matching Parameters:

• Inductance value: 220 µH
• Inductance tolerance: ±20%
• Current rating: minimum 230 mA
• DC resistance: maximum 3.69 Ohm
• Mounting type: Surface Mount
• Physical footprint: 6.60 x 6.20 x 3.00 mm (length x width x height)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute part SPD62R-224M meets all critical matching parameters. While this substitute exhibits improved electrical characteristics (lower DC resistance and higher current saturation rating), it remains within the allowed substitution envelope for this product category. The shielded construction of the substitute represents a design enhancement that does not preclude substitution in applications where the original unshielded design was specified.

Engineering Selection Recommendations

Primary Substitute: SPD62R-224M

The SPD62R-224M is the qualified substitute for CDRH62NP-221MC based on the following engineering criteria:

1. Electrical Equivalence: Both parts maintain 220 µH inductance at ±20% tolerance and operate at 1 kHz test frequency. The substitute's 320 mA current rating and 2.2 Ohm maximum DC resistance exceed the original specification, providing improved performance margin.

2. Physical Compatibility: Identical surface mount footprint (6.60 x 6.20 x 3.00 mm) ensures direct PCB layout compatibility without redesign.

3. Compliance Status: Both parts are ROHS3 compliant with MSL 1 rating, meeting regulatory and handling requirements.

4. Product Availability: The substitute is classified as Active, ensuring long-term procurement availability and supply chain continuity compared to the obsolete original part.

5. Temperature Performance: The substitute's extended operating range (-55 to 125°C) provides broader thermal margin than the original (-40 to 100°C).

Design Consideration: The substitute features shielded construction versus the original unshielded design. In applications where electromagnetic interference rejection is beneficial, this represents a design enhancement. In applications where unshielded operation is specifically required, this difference must be evaluated against circuit performance requirements.

Frequently Asked Questions (FAQ)

Q: Can SPD62R-224M be used as a direct replacement for CDRH62NP-221MC?

A: Yes. Both parts share identical inductance (220 µH), tolerance (±20%), current rating (230 mA minimum), DC resistance specification (3.69 Ohm maximum), mounting type (surface mount), and physical dimensions (6.60 x 6.20 x 3.00 mm). The substitute meets all critical electrical and mechanical parameters for direct substitution.

Q: What is the difference between shielded and unshielded construction?

A: The original CDRH62NP-221MC is unshielded; the substitute SPD62R-224M is shielded. Shielded inductors provide improved electromagnetic interference containment. This difference does not affect substitution eligibility but should be considered if the circuit design specifically requires unshielded operation.

Q: Does the lower DC resistance of the substitute affect compatibility?

A: No. The substitute's 2.2 Ohm maximum DC resistance is lower than the original 3.69 Ohm specification, representing improved performance. Lower DC resistance reduces power dissipation and heat generation, which is beneficial in all applications where the original part was used.

Q: Are there packaging differences between these parts?

A: The original part is supplied in standard packaging; the substitute is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprints. Tape & Reel packaging is standard for automated assembly processes and does not affect electrical or mechanical compatibility.

Q: What is the product status significance?

A: The original CDRH62NP-221MC is classified as obsolete, meaning Sumida has discontinued production. The substitute SPD62R-224M is classified as active, indicating current production and long-term availability from API Delevan. This ensures sustained procurement capability for new designs and production runs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CDRH62NP-221MC and SPD62R-224M are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited). Both carry EAR99 export classification and the same HTSUS code (8504.50.4000), confirming regulatory equivalence.
