Substitute Part Grouping Explanation

Substitute parts for the CDEP134-6R4MC are identified based on strict electrical and mechanical parameter matching within the allowed specifications for this inductor category. The substitution logic is based on the following criteria:

Electrical Parameters (Critical):

• Inductance value: 6.4 µH
• Inductance tolerance: ±20%
• Current rating: 7 A minimum
• Saturation current: 8 A minimum
• DC resistance: 16.3 mOhm maximum
• Shielding requirement: Shielded configuration

Mechanical Parameters (Critical):

• Mounting type: Surface mount
• Physical footprint: 13.50mm x 13.50mm
• Maximum seated height: 5.00mm
• Package type: Nonstandard

Test Conditions:

• Inductance measured at 100 kHz

Parts meeting all these parameters are classified as direct electrical and mechanical equivalents. Variations in product status, core material, or compliance certifications do not affect the substitution relationship when all electrical and mechanical parameters remain identical.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Are the CDEP134-6R4MC and CDEP134NP-6R4MC electrically identical?

A: Yes. Both parts have identical inductance (6.4 µH), current rating (7 A), saturation current (8 A), DC resistance (16.3 mOhm max), and shielding configuration. They are measured at the same test frequency (100 kHz) and share the same tolerance specification (±20%).

Q: What is the difference between these two parts?

A: The primary differences are product status, compliance certifications, operating temperature range, and packaging format. The CDEP134NP-6R4MC is active, ROHS3 compliant, operates to 125°C, and is supplied in Tape & Reel format. The CDEP134-6R4MC is obsolete, RoHS non-compliant, operates to 100°C, and uses nonstandard packaging.

Q: Can the CDEP134NP-6R4MC be used as a direct replacement in existing designs?

A: Yes. The substitute part meets all electrical and mechanical specifications of the main part. The extended operating temperature range and improved compliance status make it suitable for direct substitution in applications designed for the CDEP134-6R4MC.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical footprint dimensions (13.50mm x 13.50mm) and maximum seated height (5.00mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the significance of the extended temperature range in the substitute part?

A: The CDEP134NP-6R4MC operates to 125°C compared to 100°C for the main part. This extended range provides additional thermal margin in applications subject to elevated ambient temperatures or thermal cycling conditions.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus nonstandard) does not affect electrical performance. The Tape & Reel format of the substitute part provides advantages for automated assembly and supply chain handling.
