Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-0R9MC is a direct electrical and mechanical equivalent to the obsolete CDEP134-0R9MC. Both components share identical inductance, current rating, saturation current, DC resistance, shielding configuration, physical dimensions, and operating frequency test parameters.

The CDEP134NP-0R9MC offers the following advantages for new designs and production transitions:

Product Status: The substitute part is classified as active, ensuring ongoing availability and supply chain stability compared to the obsolete main part.

Compliance Enhancement: The CDEP134NP-0R9MC is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance improvement supports regulatory requirements in jurisdictions with RoHS mandates.

Operating Temperature Range: The substitute part extends the maximum operating temperature to 125°C, compared to 100°C for the main part. This provides additional thermal margin for applications operating at elevated temperatures within the specified range.

Packaging: The substitute part is supplied in Tape & Reel (TR) format, supporting automated assembly processes and improving handling efficiency compared to nonstandard packaging.

Core Material: The substitute part utilizes a drum core ferrite construction, whereas the main part uses standard wirewound construction. Both configurations deliver equivalent electrical performance at the specified test frequency and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the CDEP134NP-0R9MC be used as a direct replacement for the CDEP134-0R9MC in existing designs?

A: Yes. The CDEP134NP-0R9MC meets all electrical and mechanical specifications of the CDEP134-0R9MC. Inductance, current rating, saturation current, DC resistance, shielding, physical dimensions, and operating frequency are identical. The substitute part is pin-compatible and footprint-compatible for surface mount applications.

Q: What is the difference between the wirewound and drum core construction types?

A: The main part uses wirewound construction. The substitute part uses drum core wirewound construction with ferrite material. Both configurations deliver the same inductance value, current rating, and DC resistance at the specified test frequency of 100 kHz. The core material difference does not affect electrical equivalence for this application.

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

A: No. The substitute part operates from -40°C to 125°C, while the main part operates from -40°C to 100°C. The substitute part's extended upper temperature limit provides additional thermal margin and does not create incompatibility. Applications operating within the main part's original temperature range (-40°C to 100°C) remain fully compatible.

Q: What is the significance of the RoHS3 compliance on the substitute part?

A: The CDEP134NP-0R9MC is ROHS3 compliant, meeting Restriction of Hazardous Substances regulations. The main part is RoHS non-compliant. For applications subject to RoHS requirements, the substitute part satisfies regulatory compliance obligations. For applications without RoHS requirements, both parts function identically.

Q: How does the Tape & Reel packaging of the substitute part compare to the nonstandard packaging of the main part?

A: Tape & Reel (TR) packaging is a standard format for automated surface mount assembly, enabling high-speed pick-and-place operations. Nonstandard packaging may require manual handling or custom feeding systems. The substitute part's TR packaging improves manufacturing efficiency and reduces assembly costs. Electrical and mechanical performance remain equivalent.

Q: Are there any frequency-dependent performance differences between the main part and substitute part?

A: Both parts are tested at 100 kHz inductance frequency. Electrical parameters including inductance value, DC resistance, and current rating are specified at this test frequency. Performance characteristics at other frequencies are not provided in the component specifications. For applications operating at frequencies other than 100 kHz, component behavior should be evaluated based on the provided DC and AC parameters.

Q: What inventory status should be considered when selecting between the main part and substitute part?

A: The main part (CDEP134-0R9MC) is classified as obsolete with 834 pieces in stock. The substitute part (CDEP134NP-0R9MC) is classified as active with 1061 pieces in stock. For new production and long-term supply continuity, the active substitute part is the appropriate selection. The obsolete main part should be reserved for legacy system support only.
