Engineering Selection Recommendations

The CDEP134NP-1R6MC is the direct substitute for the obsolete CDEP134-1R6MC. Selection is based on the following engineering criteria:

Electrical Equivalence: All electrical parameters are identical, including inductance value, current ratings, saturation characteristics, and DC resistance. The component operates at the same test frequency (100 kHz) and maintains the same temperature operating range.

Mechanical Compatibility: Physical dimensions, mounting type, and package footprint are identical. The component is a direct drop-in replacement requiring no PCB redesign or layout modification.

Product Status: The CDEP134NP-1R6MC is classified as active, ensuring long-term availability and supply chain continuity. The main part CDEP134-1R6MC is obsolete and should not be specified for new designs.

Compliance Enhancement: The substitute part achieves ROHS3 compliance, exceeding the non-compliant status of the original part. This provides regulatory advantage for applications subject to RoHS requirements.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The original part was supplied in bulk format. This packaging difference does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-1R6MC be used as a direct replacement for CDEP134-1R6MC?

A: Yes. The CDEP134NP-1R6MC is a direct substitute with identical electrical specifications (1.6 µH inductance, 15 A current rating, 3.7 mOhm DCR) and mechanical dimensions (13.50 × 13.50 × 5.00 mm). No circuit modifications are required.

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

A: The primary differences are product status and packaging format. CDEP134-1R6MC is obsolete and supplied in bulk; CDEP134NP-1R6MC is active and supplied in Tape & Reel format. The "NP" designation indicates the active production variant. All electrical and mechanical parameters are identical.

Q: Are there any compliance differences?

A: Yes. CDEP134NP-1R6MC is ROHS3 compliant, while CDEP134-1R6MC is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part is the appropriate selection.

Q: Does the Tape & Reel packaging affect performance?

A: No. Tape & Reel packaging is a supply format used for automated assembly. It does not affect the electrical performance, mechanical compatibility, or reliability of the component. The inductor itself is identical.

Q: What is the saturation current specification?

A: The saturation current (Isat) is 16 A for both parts. This represents the current level at which the inductor begins to saturate. The continuous current rating is 15 A, providing a 1 A margin before saturation.

Q: Can this inductor be used in high-frequency applications?

A: The inductance value is tested at 100 kHz. The component is suitable for applications within this frequency range and lower. For applications requiring operation significantly above 100 kHz, frequency-dependent characteristics should be verified with the manufacturer.

Q: What is the moisture sensitivity level?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity. The component can be stored and handled without special moisture control measures.
