  • Identical mounting type: Surface Mount
  • Identical shielding configuration: Unshielded
  • Identical inductance test frequency: 1 kHz
  • Identical RoHS3 compliance status
  • Identical MSL rating: 1 (Unlimited)

Improved Parameters (CDH115NP-680KC):

  • Higher current rating: 1.2 A (vs. 760 mA)
  • Lower DC resistance: 160mOhm Max (vs. 280mOhm Max)
  • Extended operating temperature range: -40°C to 100°C (vs. -30°C to 100°C)
  • Active product status (vs. Obsolete)
  • Ferrite drum core construction (vs. standard wirewound)

The CDH115NP-680KC operates within all electrical and mechanical constraints of the original CDH113NP-680KC while providing superior performance margins and supply continuity.

Engineering Selection Recommendations

The CDH115NP-680KC is the qualified substitute for the obsolete CDH113NP-680KC based on the following engineering criteria:

Product Status Justification: The CDH113NP-680KC carries obsolete product status, indicating discontinued manufacturing and potential supply exhaustion. The CDH115NP-680KC maintains active product status with confirmed inventory availability (699 Pcs), ensuring long-term supply chain reliability.

Electrical Compatibility: Both inductors maintain identical inductance specifications (68 µH ±10%) and are tested at the same frequency (1 kHz). The substitute part's improved current rating (1.2 A vs. 760 mA) and reduced DC resistance (160mOhm vs. 280mOhm) provide superior performance margins without exceeding original design constraints.

Mechanical Compatibility: Identical footprint dimensions (11.20mm x 11.00mm) ensure PCB layout compatibility. The increased seated height (5.20mm vs. 3.70mm) requires verification of available vertical clearance in the target assembly but does not affect electrical function.

Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The substitute's extended operating temperature range (-40°C to 100°C vs. -30°C to 100°C) provides additional thermal margin.

Packaging Consideration: The CDH115NP-680KC is supplied in Tape & Reel (TR) format, supporting automated assembly processes. The original CDH113NP-680KC packaging format is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can the CDH115NP-680KC directly replace the CDH113NP-680KC on existing PCBs?

A: Direct replacement is possible with one mechanical consideration. Both parts share identical footprint dimensions (11.20mm x 11.00mm), enabling PCB layout compatibility. However, the CDH115NP-680KC has a maximum seated height of 5.20mm compared to 3.70mm for the original part. Verify available vertical clearance above the component location before implementation.

Q: Are the electrical specifications compatible between these two inductors?

A: Yes. Both inductors provide 68 µH inductance with ±10% tolerance, tested at 1 kHz. The CDH115NP-680KC operates within all electrical parameters of the CDH113NP-680KC. The substitute's higher current rating (1.2 A vs. 760 mA) and lower DC resistance (160mOhm vs. 280mOhm) represent performance improvements that do not compromise compatibility.

Q: Why is the CDH113NP-680KC classified as obsolete?

A: Obsolete product status indicates that the manufacturer has discontinued production. This classification necessitates identification of active substitute parts to maintain supply chain continuity and support long-term product availability.

Q: What is the significance of the different core materials?

A: The CDH113NP-680KC uses standard wirewound construction, while the CDH115NP-680KC employs ferrite drum core construction. Both configurations deliver the specified 68 µH inductance value. The ferrite drum core design in the substitute contributes to improved DC resistance performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDH113NP-680KC and CDH115NP-680KC maintain ROHS3 compliance status, satisfying environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating require no special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes for both parts.

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

A: The CDH115NP-680KC is supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly. The original CDH113NP-680KC packaging specification is not provided in available technical data.
