Substitute Part Grouping Explanation

Substitution eligibility for the CDEP134CNP-2R7MC-75 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 2.7 µH
• Inductance tolerance: ±20%
• Current rating: 8 A minimum
• Saturation current (Isat): 14.7 A minimum
• DC resistance (DCR): 10.8 mOhm maximum
• Core material: Ferrite
• Operating temperature range: -40°C to 125°C minimum
• Test frequency: 100 kHz

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Physical footprint: 13.50 mm × 13.50 mm
• Height compatibility: 4.90 mm maximum seated height
• Package type: Nonstandard

Compliance Criteria:

• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)

The substitute part CDEP134NP-2R7MC-H meets all electrical and mechanical equivalence criteria. The primary distinction is the transition from unshielded to shielded construction and from active to active product status, with a marginal increase in seated height (5.00 mm versus 4.90 mm).

Parameter Comparison

Engineering Selection Recommendations

CDEP134NP-2R7MC-H is the qualified substitute for CDEP134CNP-2R7MC-75 based on the following engineering factors:

Product Status Consideration: The main part CDEP134CNP-2R7MC-75 is classified as obsolete, creating supply chain risk for new production and long-term support. The substitute CDEP134NP-2R7MC-H maintains active product status with Sumida America Components Inc., ensuring continued availability and manufacturer support.

Electrical Equivalence: All critical electrical parameters are identical: 2.7 µH inductance at ±20% tolerance, 8 A current rating, 14.7 A saturation current, and 10.8 mOhm maximum DC resistance. Both components utilize ferrite core material and operate across the identical temperature range of -40°C to 125°C.

Mechanical Compatibility: Physical footprint dimensions are identical at 13.50 mm × 13.50 mm. The seated height increases from 4.90 mm to 5.00 mm, a 0.10 mm difference that remains within typical PCB assembly tolerances for surface mount applications.

Compliance and Certification: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility.

Shielding Transition: The substitute introduces shielded construction compared to the unshielded main part. Shielded inductors reduce electromagnetic interference (EMI) coupling to adjacent circuit elements, providing improved performance in noise-sensitive applications without degrading the specified electrical parameters.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments and provides improved handling and automated assembly compatibility compared to nonstandard packaging.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-2R7MC-H be used as a direct replacement for CDEP134CNP-2R7MC-75?

A: Yes. Both components share identical inductance (2.7 µH), current rating (8 A), saturation current (14.7 A), and DC resistance (10.8 mOhm maximum). The electrical performance is equivalent. The substitute features shielded construction and a 0.10 mm increase in seated height, both of which are compatible with standard PCB assembly processes.

Q: What is the significance of the shielding difference?

A: The main part is unshielded; the substitute is shielded. Shielded inductors contain electromagnetic fields more effectively, reducing EMI radiation to surrounding circuit components. This provides improved signal integrity in densely populated PCB layouts without altering the specified inductance or current handling characteristics.

Q: Does the 0.10 mm height difference affect PCB assembly?

A: No. The increase from 4.90 mm to 5.00 mm seated height is within standard PCB assembly tolerances and does not require design modifications. Standard pick-and-place equipment and reflow processes accommodate this variation.

Q: Why is the substitute in active product status while the main part is obsolete?

A: The CDEP134CNP-2R7MC-75 has been discontinued by the manufacturer. The CDEP134NP-2R7MC-H represents the current production equivalent, ensuring long-term supply availability and manufacturer technical support.

Q: Are there any temperature or frequency limitations with the substitute?

A: No. The substitute maintains the identical operating temperature range (-40°C to 125°C) and inductance test frequency (100 kHz) as the main part.

Q: What is the packaging difference, and does it matter?

A: The main part uses nonstandard packaging; the substitute uses Tape & Reel (TR) packaging. Tape & Reel is the industry standard for automated assembly and provides superior handling, storage, and pick-and-place compatibility. This is an improvement for production environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CDEP134CNP-2R7MC-75 and CDEP134NP-2R7MC-H are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting current environmental and regulatory requirements.

Q: Can I use the substitute in existing designs without circuit modifications?

A: Yes. The electrical parameters are identical, and the mechanical dimensions are compatible. No circuit design changes are required for substitution.
