CDEP134-8R0MC Equivalent & Substitute Parts

Part Overview

The CDEP134-8R0MC is an 8 µH shielded wirewound inductor manufactured by Sumida America Components Inc., rated for 6.5 A continuous current with a maximum DC resistance of 18.4 mOhm. This component is designed for surface mount applications in nonstandard package configurations and operates across the temperature range of -40°C to 100°C.

The CDEP134-8R0MC has reached obsolete product status. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this inductor is specified in circuit designs.

Substitute Part Grouping Explanation

Substitution of the CDEP134-8R0MC is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 8 µH
• Inductance tolerance: ±20%
• Current rating: 6.5 A minimum
• Saturation current: 7.2 A minimum
• DC resistance: 18.4 mOhm maximum
• Shielding: Shielded construction required

Mechanical Equivalence Criteria:

• Mounting type: Surface mount
• Package configuration: Nonstandard
• Physical footprint: 13.50mm x 13.50mm
• Height constraint: 5.00mm maximum seated height

Test Conditions:

• Inductance measured at 100 kHz

The substitute part CDEP134NP-8R0MC meets all electrical and mechanical equivalence requirements and is therefore a direct substitute for the obsolete CDEP134-8R0MC.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-8R0MC is a direct electrical and mechanical substitute for the obsolete CDEP134-8R0MC. Selection of this substitute part is supported by the following factors:

Electrical Compatibility: All critical electrical parameters—inductance, current rating, saturation current, and DC resistance—are identical between the main part and substitute. Both components are shielded and tested at 100 kHz, ensuring equivalent performance in circuit applications.

Mechanical Compatibility: Physical footprint and mounting type are identical. The substitute part features a slightly lower seated height (4.90mm versus 5.00mm), which provides improved board-level clearance and is compatible with existing PCB layouts designed for the main part.

Thermal Performance: The substitute part extends the operating temperature range to -40°C to 125°C, compared to the main part's -40°C to 100°C. This provides additional thermal margin for applications operating at elevated temperatures.

Product Status and Compliance: The CDEP134NP-8R0MC is an active product with ROHS3 compliance, whereas the main part is obsolete and RoHS non-compliant. Adoption of the substitute part ensures long-term supply availability and regulatory compliance for new designs and production runs.

Packaging: The substitute part is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations and provides cost efficiency for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can the CDEP134NP-8R0MC be used as a direct replacement for the CDEP134-8R0MC in existing designs?

A: Yes. The CDEP134NP-8R0MC meets all electrical and mechanical equivalence criteria. Inductance, current rating, saturation current, DC resistance, shielding, footprint, and mounting type are identical. The substitute part is pin-compatible and functionally equivalent for circuit operation.

Q: What is the difference between the main part and the substitute?

A: The primary differences are: (1) the substitute uses a drum core ferrite construction versus unspecified core material in the main part; (2) the substitute has a slightly lower seated height (4.90mm vs. 5.00mm); (3) the substitute offers an extended operating temperature range (-40°C to 125°C vs. -40°C to 100°C); (4) the substitute is ROHS3 compliant and actively manufactured, whereas the main part is obsolete and RoHS non-compliant; (5) the substitute is supplied in Tape & Reel packaging.

Q: Are there any height clearance concerns when substituting the CDEP134NP-8R0MC?

A: No. The substitute part has a lower maximum seated height (4.90mm) compared to the main part (5.00mm). This provides improved clearance and is compatible with PCB layouts designed for the original component.

Q: What is the temperature operating range for each part?

A: The CDEP134-8R0MC operates from -40°C to 100°C. The CDEP134NP-8R0MC operates from -40°C to 125°C. The substitute part provides an additional 25°C of upper temperature margin.

Q: Is the CDEP134NP-8R0MC available in production quantities?

A: Yes. The CDEP134NP-8R0MC is an active product with 2412 pieces in stock as new original inventory. The main part CDEP134-8R0MC is obsolete but has 1162 pieces available.

Q: What packaging format is used for the substitute part?

A: The CDEP134NP-8R0MC is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly operations.

Q: Are both parts RoHS compliant?

A: No. The main part CDEP134-8R0MC is RoHS non-compliant. The substitute part CDEP134NP-8R0MC is ROHS3 compliant, meeting current regulatory requirements for electronic components.

Q: Do both parts have the same inductance tolerance?

A: Yes. Both the CDEP134-8R0MC and CDEP134NP-8R0MC have an inductance tolerance of ±20% at 100 kHz test frequency.

Q: What is the moisture sensitivity level for these inductors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.
