Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDH113NP-100MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% (must be equal or tighter)
• Mounting type: Surface Mount (exact match required)
• Package footprint: Nonstandard 11.20mm x 11.00mm (exact match required)
• Shielding configuration: Unshielded (exact match required)

Secondary Compatibility Criteria:

• Current rating: Must equal or exceed 2 A
• DC resistance: Must equal or be lower than 47mOhm Max
• Operating temperature range: Must encompass or exceed -30°C ~ 100°C
• RoHS compliance: ROHS3 Compliant (required)
• Moisture sensitivity: MSL 1 (required)

The CDH115NP-100MC qualifies as a direct substitute based on these parameters. It maintains identical inductance, tolerance, mounting type, footprint dimensions, and shielding characteristics while offering improved electrical performance through lower DC resistance and higher current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

The CDH115NP-100MC is a qualified substitute for the obsolete CDH113NP-100MC based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains identical inductance (10 µH) and tolerance (±20%), ensuring equivalent circuit performance. The lower DC resistance (28mOhm vs. 47mOhm) and higher current rating (3 A vs. 2 A) provide improved electrical performance margins without introducing incompatibility.

Physical Compatibility: Both parts share identical footprint dimensions (11.20mm x 11.00mm) and mounting type (Surface Mount), ensuring PCB layout compatibility. The increased seated height of the CDH115NP-100MC (5.20mm vs. 3.70mm) must be evaluated against available board clearance in the target application.

Compliance & Supply Status: The CDH115NP-100MC carries active product status from Sumida America Components Inc., ensuring ongoing availability and supply chain reliability. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting regulatory and environmental requirements.

Material & Construction: The CDH115NP-100MC features a drum core ferrite construction compared to the standard wirewound design of the CDH113NP-100MC. This construction difference contributes to the improved DC resistance and current rating while maintaining unshielded configuration.

Frequently Asked Questions (FAQ)

Q: Can the CDH115NP-100MC be used as a direct replacement for CDH113NP-100MC in existing designs?

A: The CDH115NP-100MC is electrically compatible as a substitute. The identical inductance, tolerance, and footprint dimensions ensure circuit functionality. However, the increased seated height (5.20mm vs. 3.70mm) requires verification of available vertical clearance on the PCB assembly.

Q: What are the key differences between these two inductors?

A: The primary differences are: (1) Current rating: CDH115NP-100MC rated for 3 A versus CDH113NP-100MC at 2 A; (2) DC resistance: CDH115NP-100MC at 28mOhm Max versus CDH113NP-100MC at 47mOhm Max; (3) Core construction: CDH115NP-100MC uses drum core ferrite versus standard wirewound; (4) Operating temperature range: CDH115NP-100MC extends to -40°C versus -30°C minimum; (5) Seated height: CDH115NP-100MC at 5.20mm versus 3.70mm; (6) Product status: CDH115NP-100MC is active versus obsolete.

Q: Why is the CDH113NP-100MC obsolete?

A: The CDH113NP-100MC is designated as obsolete by Sumida America Components Inc. The CDH115NP-100MC represents the active product line continuation with enhanced electrical performance characteristics.

Q: Are there any electrical performance advantages to using the CDH115NP-100MC?

A: The CDH115NP-100MC provides lower DC resistance (28mOhm vs. 47mOhm), resulting in reduced power dissipation and heat generation. The higher current rating (3 A vs. 2 A) provides additional design margin for current transients or future application scaling.

Q: What packaging options are available for the CDH115NP-100MC?

A: The CDH115NP-100MC is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The CDH113NP-100MC packaging format is not specified in the available data.

Q: Do both parts meet the same compliance standards?

A: Both the CDH113NP-100MC and CDH115NP-100MC are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What is the inductance tolerance specification?

A: Both parts maintain ±20% inductance tolerance, measured at 1 kHz test frequency. This tolerance applies equally to both the main part and substitute.
