Substitute Part Grouping Explanation

Substitution of the CDH113NP-560KC is determined by strict equivalence in the following parameters:

Primary Equivalence Criteria:

Inductance value: 56 µH (±10% tolerance maintained)
Mounting type: Surface Mount
Physical footprint: 11.20mm L x 11.00mm W (identical base dimensions)
Unshielded configuration
RoHS3 compliance status

Secondary Compatibility Factors:

Current rating must equal or exceed 800 mA
DC resistance must not exceed 240mOhm to maintain circuit performance
Operating temperature range must encompass the original specification
Moisture sensitivity level MSL 1 or better

The CDH115NP-560KC qualifies as a direct substitute based on matching inductance, tolerance, footprint dimensions, unshielded design, and regulatory compliance. Enhanced current rating (1.28 A vs. 800 mA) and improved DC resistance (140mOhm vs. 240mOhm) provide superior performance margins within the same physical envelope.

Engineering Selection Recommendations

The CDH115NP-560KC is the qualified substitute for the obsolete CDH113NP-560KC based on the following engineering factors:

Product Status Alignment: The CDH115NP-560KC maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete CDH113NP-560KC.

Electrical Performance: Both parts deliver identical inductance (56 µH ±10%) at the 1 kHz test frequency. The CDH115NP-560KC provides enhanced current handling (1.28 A vs. 800 mA) and reduced DC resistance (140mOhm vs. 240mOhm), resulting in lower power dissipation and improved thermal performance in the same physical footprint.

Regulatory Compliance: Both components meet ROHS3 compliance requirements and maintain MSL 1 moisture sensitivity classification, ensuring compatibility with modern manufacturing and environmental standards.

Physical Compatibility: Identical base footprint dimensions (11.20mm x 11.00mm) support direct PCB layout reuse. The CDH115NP-560KC exhibits increased seated height (5.20mm vs. 3.70mm), which must be verified against available board clearance in the target application.

Temperature Performance: The CDH115NP-560KC extends the lower operating temperature limit to -40°C, providing broader environmental coverage than the original -30°C specification.

Frequently Asked Questions (FAQ)

Q: Can the CDH115NP-560KC be used as a direct replacement for the CDH113NP-560KC?

A: Yes. Both components share identical inductance (56 µH ±10%), footprint dimensions (11.20mm x 11.00mm), unshielded configuration, and regulatory compliance. The CDH115NP-560KC is electrically and mechanically compatible for direct substitution.

Q: What is the primary difference between these two inductors?

A: The CDH115NP-560KC offers superior electrical performance with higher current rating (1.28 A vs. 800 mA) and lower DC resistance (140mOhm vs. 240mOhm). The CDH115NP-560KC also features active production status versus the obsolete CDH113NP-560KC. Height differs by 1.50mm (5.20mm vs. 3.70mm).

Q: Will the increased height of the CDH115NP-560KC affect PCB assembly?

A: The CDH115NP-560KC has a maximum seated height of 5.20mm compared to 3.70mm for the CDH113NP-560KC. Verify available vertical clearance on the target PCB before implementation. The identical base footprint (11.20mm x 11.00mm) allows direct pad reuse.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDH113NP-560KC and CDH115NP-560KC are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the inductance tolerance for both parts?

A: Both inductors maintain ±10% inductance tolerance at the 1 kHz test frequency, ensuring equivalent circuit performance.

Q: Why is the CDH113NP-560KC listed as obsolete?

A: The CDH113NP-560KC has been discontinued from active production by Sumida America Components Inc. The CDH115NP-560KC represents the active production equivalent with enhanced specifications.

Q: Can I use the CDH115NP-560KC in applications requiring the full 800 mA rating?

A: Yes. The CDH115NP-560KC is rated for 1.28 A continuous current, which exceeds the 800 mA requirement of the original CDH113NP-560KC specification.
