Substitute Part Grouping Explanation

Substitution of the CDH113NP-151KC is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Identical inductance value: 150 µH
• Identical inductance tolerance: ±10%
• Identical mounting type: Surface Mount
• Identical shielding configuration: Unshielded
• Identical physical footprint dimensions: 0.441" L x 0.433" W (11.20mm x 11.00mm)
• Identical RoHS3 compliance status
• Identical moisture sensitivity level: MSL 1

Allowable Parameter Variations:

• Current rating may exceed the original specification (higher current capability is acceptable)
• DC resistance may be lower than the original specification (improved performance is acceptable)
• Operating temperature range may be extended (broader range is acceptable)
• Height may vary within the nonstandard package classification
• Core material composition may differ while maintaining unshielded wirewound construction

The CDH115NP-151KC meets all primary substitution criteria and demonstrates improved electrical performance characteristics.

Engineering Selection Recommendations

The CDH115NP-151KC is a direct functional substitute for the obsolete CDH113NP-151KC based on the following engineering considerations:

Electrical Compatibility: The substitute part maintains identical inductance (150 µH) and tolerance (±10%) specifications. The improved current rating (760 mA versus 490 mA) and reduced DC resistance (400mOhm Max versus 610mOhm Max) provide enhanced electrical performance without compromising circuit function. Both components are unshielded wirewound inductors suitable for identical application requirements.

Mechanical Compatibility: The footprint dimensions are identical (0.441" L x 0.433" W / 11.20mm x 11.00mm), ensuring compatibility with existing PCB layouts. The substitute component exhibits a greater seated height (0.205" versus 0.146"), which requires verification of available vertical clearance in the assembly design.

Compliance and Availability: Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings. The CDH115NP-151KC is classified as active product status with confirmed inventory availability (1101 pieces), whereas the CDH113NP-151KC is obsolete. The substitute component is manufactured by the same supplier (Sumida America Components Inc.) and shares identical ECCN and HTSUS classifications.

Temperature Performance: The substitute component extends the lower operating temperature limit to -40°C, providing broader environmental operating range compared to the original -30°C specification.

Frequently Asked Questions (FAQ)

Q: Can the CDH115NP-151KC be used as a direct replacement for the CDH113NP-151KC?

A: The CDH115NP-151KC is electrically and mechanically compatible for direct substitution based on identical inductance, tolerance, mounting type, and footprint dimensions. The primary design consideration is the increased seated height (5.20mm versus 3.70mm), which must be verified against available vertical clearance in the assembly.

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

A: The CDH115NP-151KC provides improved electrical performance with higher current rating (760 mA versus 490 mA) and lower DC resistance (400mOhm Max versus 610mOhm Max). The inductance value and tolerance remain identical at 150 µH ±10%.

Q: Are there any compliance or certification differences?

A: Both components maintain identical ROHS3 compliance status, MSL 1 moisture sensitivity rating, ECCN classification (EAR99), and HTSUS code (8504.50.4000). No compliance differences exist between the two parts.

Q: What is the primary reason for substitution?

A: The CDH113NP-151KC is classified as obsolete product status. The CDH115NP-151KC is an active product manufactured by the same supplier with confirmed inventory availability, making it the appropriate alternative for new designs and component replenishment.

Q: Does the height difference affect PCB assembly compatibility?

A: The substitute component is 0.059" (1.50mm) taller than the original part. This dimension must be evaluated against the specific PCB assembly design to ensure adequate clearance above the component. If vertical space is constrained, alternative solutions may be required.

Q: Are both components available in the same packaging format?

A: The CDH113NP-151KC is supplied in standard packaging, while the CDH115NP-151KC is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprint dimensions.
