0512CDMCDS-100MC Equivalent & Substitute Parts

Part Overview

The 0512CDMCDS-100MC is a 10 µH shielded wirewound inductor manufactured by Sumida America Components Inc., rated for 1.1 A continuous current with 290mOhm DC resistance. This component is classified as obsolete product status. Identification of equivalent and substitute parts is necessary due to obsolescence and potential supply discontinuation. Substitute parts must maintain electrical compatibility across inductance value, current rating, shielding characteristics, and operating temperature range while accommodating mechanical form factor variations.

Substitute Part Grouping Explanation

Substitute parts for the 0512CDMCDS-100MC are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance specification)
• Current rating: minimum 1.1 A continuous (equal or greater acceptable)
• DC resistance: 290mOhm maximum (lower values acceptable for reduced losses)
• Saturation current: minimum 2.5 A (equal or greater acceptable)
• Shielding: shielded construction (required for EMI performance)
• Inductance test frequency: 100 kHz (measurement standard)

Environmental & Compliance Criteria:

• Operating temperature range: -40°C to 105°C minimum (extended ranges acceptable)
• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) or equivalent

Mechanical Criteria:

Engineering Selection Recommendations

Primary Substitute: IHLP2020BZER100M01

The IHLP2020BZER100M01 is the qualified substitute for the obsolete 0512CDMCDS-100MC based on the following engineering factors:

Electrical Performance: All critical electrical parameters match or exceed the original specification. The 10 µH inductance value and ±20% tolerance are identical. The substitute's 2.3 A current rating and 4 A saturation current both exceed the original 1.1 A and 2.5 A specifications, providing design margin. The DC resistance of 199 mOhm maximum is lower than the original 290 mOhm, resulting in reduced power dissipation and improved efficiency.

Compliance & Availability: The substitute maintains ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and manufacturing process compatibility. The substitute is classified as active product status with 25,467 units in stock, providing reliable long-term supply availability compared to the obsolete original part.

Environmental Performance: The substitute's operating temperature range of -55°C to 125°C exceeds the original -40°C to 105°C specification, supporting extended thermal operating conditions. The specified 20 MHz self-resonant frequency provides additional design reference data not available for the original part.

Mechanical Compatibility: Both parts are surface mount inductors with nonstandard package form factors. Physical dimensions are nearly identical (0.216" L x 0.204" W vs. 0.217" L x 0.205" W), with the substitute height of 0.079" (2.00mm) exceeding the original 0.047" (1.20mm). PCB layout verification is required to confirm height clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the IHLP2020BZER100M01 directly replace the 0512CDMCDS-100MC without circuit modification?

A: Electrical substitution is valid based on matching inductance, tolerance, and shielding specifications. The substitute's superior current rating and lower DC resistance provide improved performance margins. However, the increased height (2.00mm vs. 1.20mm) requires verification of PCB clearance and component placement constraints. No circuit modifications are necessary if mechanical clearance is confirmed.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The IHLP2020BZER100M01 exhibits 199 mOhm maximum DC resistance compared to the original 290 mOhm. Lower DC resistance reduces I²R power dissipation at the rated 1.1 A operating current, resulting in lower component temperature rise and improved thermal performance. This represents an engineering improvement over the original specification.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The substitute includes REACH Unaffected status, providing additional regulatory documentation. No compliance barriers exist for substitution in applications requiring these certifications.

Q: Why is the substitute part's saturation current specification important?

A: Saturation current (Isat) defines the current level at which the inductor's inductance value begins to degrade due to core saturation. The substitute's 4 A Isat compared to the original 2.5 A provides greater margin above the 1.1 A operating current, ensuring stable inductance performance across the full operating range and transient conditions.

Q: What design considerations apply to the increased component height?

A: The substitute height of 2.00mm exceeds the original 1.20mm by 0.80mm. PCB layout review is required to confirm clearance with adjacent components, solder mask patterns, and any conformal coating or potting processes. If height constraints exist, alternative substitutes or circuit redesign may be necessary.

Q: How does the specified self-resonant frequency affect circuit performance?

A: The substitute's 20 MHz self-resonant frequency indicates the frequency at which the inductor's parasitic capacitance resonates with its inductance. This specification is relevant for high-frequency applications above 1 MHz. For DC and low-frequency applications below 100 kHz, this parameter has minimal impact on circuit performance.

Q: Is the substitute part available in the same packaging format?

A: The substitute is supplied in Cut Tape (CT) and Digi-Reel® packaging, differing from the original part's packaging specification. Both formats are standard surface mount component packaging suitable for automated assembly processes. Packaging format selection depends on production volume and assembly equipment compatibility.
