CDH63NP-100MC Equivalent & Substitute Parts

Part Overview

The CDH63NP-100MC is a 10 µH unshielded wirewound surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 1.1 A continuous current with a maximum DC resistance of 209 mOhm and operates at 100 kHz test frequency. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement continuity. Substitute parts must maintain the 10 µH inductance specification and ±20% tolerance while accommodating variations in current rating, DC resistance, and shielding characteristics within acceptable application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH63NP-100MC is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 10 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Mounting type: Surface Mount (fixed requirement)
• Inductance test frequency: 100 kHz (fixed requirement)

Secondary Compatibility Parameters:

• Current rating: Substitute must equal or exceed 1.1 A
• DC resistance: Substitute must not exceed 209 mOhm Max
• Saturation current (Isat): Substitute must equal or exceed 1.2 A
• Physical dimensions: Substitute footprint must be compatible with PCB layout constraints
• RoHS and MSL compliance: Substitute must maintain ROHS3 Compliant and MSL 1 status

Allowable Variations:

• Shielding: Unshielded or shielded configurations are acceptable based on application electromagnetic environment requirements
• Core material: Ferrite or wirewound core types are acceptable
• Product status: Active status preferred for long-term availability

The substitute parts B82462A4103M000 and SPD62R-103M meet all primary criteria and maintain compatibility with the original CDH63NP-100MC electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

B82462A4103M000 (EPCOS - TDK Electronics)

This substitute provides improved electrical performance relative to the CDH63NP-100MC. The DC resistance is reduced to 140 mOhm Max (compared to 209 mOhm Max), resulting in lower power dissipation. Current rating of 1.15 A exceeds the original 1.1 A specification, and saturation current of 1.8 A provides additional margin. The ferrite drum core construction with unshielded configuration maintains electromagnetic compatibility with the original design. Active product status ensures long-term availability and supply chain continuity. Operating temperature range of -55°C to 150°C supports extended thermal applications. Self-resonant frequency of 32 MHz is specified. Tape & Reel packaging supports automated assembly processes. ROHS3 compliance and MSL 1 rating match the original component.

SPD62R-103M (API Delevan Inc.)

This substitute offers the highest current rating at 1.4 A with saturation current of 1.4 A, providing maximum headroom for current-limited applications. DC resistance of 180 mOhm Max is intermediate between the original and the EPCOS alternative. The shielded configuration reduces electromagnetic coupling to adjacent circuit elements, beneficial in noise-sensitive applications. Ferrite drum core construction ensures stable inductance across the operating frequency range. Active product status guarantees procurement availability. Operating temperature range of -55°C to 125°C covers standard industrial applications. Tape & Reel packaging supports high-volume assembly. ROHS3 compliance and MSL 1 rating are maintained. Physical dimensions are slightly larger (0.260" L x 0.244" W) than the original, requiring PCB layout verification.

Selection Basis:

Both substitute parts satisfy all primary electrical criteria: 10 µH inductance at ±20% tolerance, surface mount configuration, and 100 kHz test frequency. Both maintain ROHS3 compliance and MSL 1 moisture sensitivity rating. The choice between B82462A4103M000 and SPD62R-103M depends on application-specific requirements: select B82462A4103M000 for lowest DC resistance and extended temperature range; select SPD62R-103M for maximum current rating and shielded operation in electromagnetically congested environments.

Frequently Asked Questions (FAQ)

Q: Can the CDH63NP-100MC be directly replaced with B82462A4103M000 or SPD62R-103M?

A: Both substitute parts maintain the 10 µH inductance specification at ±20% tolerance and are rated for surface mount assembly at 100 kHz test frequency. Physical dimensions differ slightly; PCB layout verification is required to confirm footprint compatibility. Both substitutes exceed the original current rating and saturation current specifications, providing design margin.

Q: What is the difference between the unshielded CDH63NP-100MC and the shielded SPD62R-103M?

A: Shielding reduces electromagnetic field coupling to adjacent components and traces. The unshielded CDH63NP-100MC generates a magnetic field that may couple into nearby circuits. The shielded SPD62R-103M contains this field, reducing cross-talk in densely populated PCB layouts. Shielding increases component height and may affect thermal dissipation. Selection depends on electromagnetic environment and circuit layout constraints.

Q: Why does B82462A4103M000 have lower DC resistance than the original CDH63NP-100MC?

A: DC resistance is determined by wire gauge, winding configuration, and core material. The B82462A4103M000 uses ferrite drum core construction with optimized winding geometry, resulting in 140 mOhm Max compared to 209 mOhm Max for the original. Lower DC resistance reduces I²R power dissipation and improves thermal performance.

Q: Are there temperature range differences between the substitute parts?

A: B82462A4103M000 operates from -55°C to 150°C, while SPD62R-103M operates from -55°C to 125°C. The EPCOS part supports higher maximum temperature applications. Original CDH63NP-100MC operating temperature is not specified. Application thermal requirements determine which substitute is appropriate.

Q: Do both substitute parts support automated assembly?

A: Yes. Both B82462A4103M000 and SPD62R-103M are supplied in Tape & Reel (TR) packaging, standard for surface mount pick-and-place equipment. The original CDH63NP-100MC packaging format is not specified.

Q: What is the significance of the self-resonant frequency specification?

A: Self-resonant frequency (SRF) indicates the frequency at which the inductor transitions from inductive to capacitive behavior due to parasitic capacitance. B82462A4103M000 specifies 32 MHz SRF, ensuring inductive behavior across the 100 kHz test frequency and typical RF applications below 32 MHz. SPD62R-103M and the original CDH63NP-100MC do not specify SRF; this parameter should be obtained from the manufacturer if high-frequency performance is critical.

Q: Are there compliance or certification differences?

A: All three parts are ROHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity). B82462A4103M000 carries AEC-Q200 automotive qualification and REACH Unaffected status. SPD62R-103M carries REACH Unaffected status. These certifications support automotive and regulated industry applications.

Q: What inventory status should influence the selection decision?

A: CDH63NP-100MC is obsolete with 745 pieces in stock. B82462A4103M000 is active with 849 pieces available. SPD62R-103M is active with 10,375 pieces available. For long-term production, active status parts ensure sustained supply. SPD62R-103M offers the highest inventory availability.
