The SCEP105H-R80 meets the specified electrical and mechanical requirements for substitution with the CDEP105MENP-R80PC.

Parameter Comparison

Engineering Selection Recommendations

The SCEP105H-R80 is identified as a substitute for the obsolete CDEP105MENP-R80PC based on the following engineering factors:

Electrical Performance: The SCEP105H-R80 maintains the same 800 nH inductance value and shielded configuration. The substitute exhibits a tighter inductance tolerance (±20% versus ±25%), which provides improved consistency. However, the continuous current rating of 13.5 A is lower than the main part's 16.5 A rating, and the saturation current (Isat) of 25.2 A is lower than 28 A. The DC resistance of 5.3 mOhm exceeds the main part's 3.1 mOhm maximum specification.

Mechanical Compatibility: Both components are surface mount inductors with nonstandard packages. The SCEP105H-R80 has a smaller footprint (10.40 × 10.40 mm versus 11.00 × 10.00 mm) and is marginally taller (5.60 mm versus 5.50 mm). These dimensional differences require verification against specific PCB layout constraints.

Compliance and Availability: The SCEP105H-R80 is ROHS3 compliant and carries MSL rating 1 (Unlimited), matching the main part's environmental specifications. The substitute is actively manufactured and available in standard tape and reel packaging, addressing the supply discontinuity created by the main part's obsolete status.

Application Suitability: Selection of the SCEP105H-R80 as a substitute is appropriate only for applications where the lower current ratings (13.5 A continuous, 25.2 A saturation) and higher DC resistance (5.3 mOhm) are acceptable within the circuit design margins. Applications requiring the full 16.5 A continuous current rating or the lower 3.1 mOhm DCR specification of the main part require alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the SCEP105H-R80 be used as a direct replacement for the CDEP105MENP-R80PC?

A: The SCEP105H-R80 is electrically and mechanically compatible for applications that do not require the full current rating or minimum DC resistance of the main part. The substitute has a continuous current rating of 13.5 A (versus 16.5 A) and DC resistance of 5.3 mOhm (versus 3.1 mOhm maximum). Verify that your circuit design operates within these reduced specifications before substitution.

Q: What are the key differences between these two inductors?

A: The primary differences are: (1) continuous current rating: 16.5 A main part versus 13.5 A substitute; (2) saturation current: 28 A main part versus 25.2 A substitute; (3) DC resistance: 3.1 mOhm main part versus 5.3 mOhm substitute; (4) inductance tolerance: ±25% main part versus ±20% substitute; (5) core material: metal composite main part versus unspecified substitute; (6) construction type: unspecified main part versus wirewound substitute; (7) physical dimensions: 11.00 × 10.00 mm main part versus 10.40 × 10.40 mm substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDEP105MENP-R80PC and SCEP105H-R80 are ROHS3 compliant and carry MSL rating 1 (Unlimited).

Q: What is the impact of the higher DC resistance in the substitute part?

A: The SCEP105H-R80 has a DC resistance of 5.3 mOhm compared to the main part's 3.1 mOhm maximum. This 2.2 mOhm difference results in increased resistive losses and heat generation in the inductor. For applications sensitive to power dissipation or thermal performance, this difference must be evaluated against circuit requirements.

Q: Will the SCEP105H-R80 fit in the same PCB footprint?

A: The SCEP105H-R80 has a smaller footprint (10.40 × 10.40 mm) compared to the main part (11.00 × 10.00 mm), which provides layout flexibility. However, the substitute is marginally taller (5.60 mm versus 5.50 mm). Verify that the reduced footprint and increased height are compatible with your specific PCB design and component placement constraints.

Q: What is the difference between metal composite and wirewound core construction?

A: The main part uses metal composite core material, while the substitute uses wirewound construction. These different core materials and construction methods affect inductor characteristics including frequency response, saturation behavior, and thermal performance. The specific impact depends on your application's frequency range and operating conditions.

Q: Is the SCEP105H-R80 actively manufactured?

A: Yes. The SCEP105H-R80 is classified as active product status and is available in standard tape and reel packaging, ensuring ongoing supply availability.
