Substitute Part Grouping Explanation

Substitution of the CDEP134-4R8MC-H is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 4.8 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Current rating: 7 A minimum continuous
• Saturation current (Isat): 11 A minimum
• DC resistance (DCR): 16.3 mOhm maximum
• Shielding: Shielded construction required

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Physical footprint: 13.50 mm × 13.50 mm
• Maximum seated height: 5.00 mm
• Operating temperature range: -40°C to 100°C minimum

Compliance Considerations:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN and HTSUS classifications must align

Substitute parts must satisfy all electrical parameters within specified tolerances and maintain identical or compatible mechanical form factors to ensure direct replacement capability in existing PCB layouts.

Engineering Selection Recommendations

CDEP134NP-4R8MC-H is the direct substitute for CDEP134-4R8MC-H based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match exactly: 4.8 µH inductance, 7 A current rating, 11 A saturation current, and 16.3 mOhm maximum DC resistance. Both components are tested at 100 kHz and maintain ±20% inductance tolerance. The substitute's ferrite drum core construction achieves identical electrical performance within the specified parameters.

Mechanical Compatibility: Physical dimensions, mounting type, and form factor are identical. Both components occupy 13.50 mm × 13.50 mm footprint with 5.00 mm maximum seated height, ensuring direct PCB layout compatibility without redesign.

Thermal Performance: The substitute CDEP134NP-4R8MC-H operates across -40°C to 125°C, exceeding the original part's -40°C to 100°C range. This extended upper temperature limit provides additional operational margin.

Compliance and Supply Status: The substitute is active product status with ROHS3 compliance, addressing the obsolete status and RoHS non-compliance of the original part. Tape & Reel packaging supports automated assembly processes. Current inventory of 878 pieces ensures supply availability.

Selection Basis: Selection is based strictly on electrical parameter equivalence, mechanical form factor compatibility, product status transition from obsolete to active, and regulatory compliance improvement. No additional testing or verification is required for direct substitution in applications designed for CDEP134-4R8MC-H.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-4R8MC-H replace CDEP134-4R8MC-H in existing designs?

A: Yes. Both components share identical inductance (4.8 µH), current rating (7 A), saturation current (11 A), DC resistance (16.3 mOhm maximum), shielding, and physical dimensions (13.50 × 13.50 × 5.00 mm). Direct substitution is supported without circuit redesign or PCB layout modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance. CDEP134-4R8MC-H is obsolete and RoHS non-compliant. CDEP134NP-4R8MC-H is active production status and ROHS3 compliant. The substitute also specifies ferrite drum core construction and Tape & Reel packaging. Electrical and mechanical performance are equivalent.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The substitute's -40°C to 125°C operating range encompasses the original part's -40°C to 100°C specification. Extended temperature capability provides additional operational margin without affecting performance within the original design envelope.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly. Both components have identical physical form factors and mounting types (Surface Mount).

Q: What is the significance of the ferrite drum core in the substitute?

A: The substitute specifies ferrite drum core construction, whereas the original part's core material is not specified. This construction achieves the required 4.8 µH inductance and electrical performance within the identical physical envelope and electrical parameter limits.

Q: Is the ±20% inductance tolerance maintained in the substitute?

A: Yes. Both components maintain ±20% inductance tolerance at 100 kHz test frequency, ensuring equivalent circuit performance and design margin.

Q: Can the substitute be used in new designs?

A: Yes. CDEP134NP-4R8MC-H is active production status with ROHS3 compliance, making it suitable for new designs requiring 4.8 µH shielded inductors rated for 7 A continuous current with 16.3 mOhm maximum DC resistance in Surface Mount packages.
