Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDH113NP-181KC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 180 µH at 1 kHz test frequency
• Inductance tolerance: ±10%
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Physical footprint compatibility: 11.20mm L x 11.00mm W base dimensions

Secondary Compatibility Factors:

• Current rating must equal or exceed 450 mA
• DC resistance must not exceed 750mOhm
• Operating temperature range must encompass or exceed -30°C to 100°C
• RoHS3 compliance and MSL 1 rating required

The CDH115NP-181KC meets all primary matching criteria and provides enhanced electrical performance characteristics, making it a valid substitute for the obsolete CDH113NP-181KC.

Parameter Comparison

Engineering Selection Recommendations

The CDH115NP-181KC is the designated substitute for the obsolete CDH113NP-181KC based on the following engineering factors:

Electrical Compatibility: Both parts maintain identical inductance values (180 µH ±10%) at the standard 1 kHz test frequency. The CDH115NP-181KC provides superior electrical performance with a current rating of 720 mA compared to the 450 mA rating of the main part, and reduced DC resistance of 450mOhm maximum versus 750mOhm maximum. These improvements ensure the substitute part operates within acceptable thermal and electrical margins for applications designed around the original specification.

Compliance and Certification: Both parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance for manufacturing and field deployment.

Product Availability: The CDH115NP-181KC is classified as Active product status with confirmed inventory availability (1172 Pcs), whereas the CDH113NP-181KC is obsolete. This substitution ensures continued supply chain access for production requirements.

Physical Considerations: The substitute part maintains the same base footprint (11.20mm L x 11.00mm W) for PCB layout compatibility. The seated height increases from 3.70mm to 5.20mm maximum, requiring verification of available vertical clearance in the target application.

Temperature Range: The CDH115NP-181KC extends the lower operating temperature limit to -40°C compared to -30°C for the main part, providing enhanced performance in cold environment applications.

Frequently Asked Questions (FAQ)

Q: Can the CDH115NP-181KC be used as a direct replacement for the CDH113NP-181KC?

A: The CDH115NP-181KC is electrically compatible as a substitute. Both parts share identical inductance values (180 µH ±10%), unshielded configuration, and surface mount design. The substitute provides improved current handling (720 mA vs. 450 mA) and lower DC resistance (450mOhm vs. 750mOhm). Physical footprint compatibility is maintained on the base dimensions (11.20mm x 11.00mm). The seated height difference (5.20mm vs. 3.70mm) must be evaluated for PCB clearance constraints.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are current rating and DC resistance. The CDH115NP-181KC is rated for 720 mA continuous current with 450mOhm maximum DC resistance, compared to 450 mA and 750mOhm for the CDH113NP-181KC. Both maintain the same 180 µH inductance value and ±10% tolerance at 1 kHz test frequency.

Q: Are there any packaging differences?

A: The CDH113NP-181KC is supplied in standard packaging, while the CDH115NP-181KC is supplied in Tape & Reel (TR) format. Both use nonstandard package cases. The physical component dimensions differ only in seated height: 3.70mm maximum for the main part versus 5.20mm maximum for the substitute.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CDH113NP-181KC and CDH115NP-181KC are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: What is the temperature operating range for each part?

A: The CDH113NP-181KC operates from -30°C to 100°C. The CDH115NP-181KC operates from -40°C to 100°C, providing an extended lower temperature limit of 10°C.

Q: Why is the CDH113NP-181KC obsolete?

A: The CDH113NP-181KC is classified as obsolete product status. The CDH115NP-181KC is the active equivalent offering superior electrical performance and continued manufacturer support.
