SCEP147L-8R0 Equivalent & Substitute Parts

Part Overview

The SCEP147L-8R0 is an 8 µH shielded inductor manufactured by Signal Transformer, rated for 11.5 A continuous current with a maximum DC resistance of 7.8 mOhm. This surface mount component operates across the industrial temperature range of -40°C to 125°C and is specified for 100 kHz inductance testing. The part is Active status and ROHS3 compliant, making it suitable for modern electronic applications requiring regulated inductance performance in compact form factors.

Substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits equivalent performance specifications. The CDEP147NP-8R0MC-125 from Sumida America Components Inc. provides functional equivalence based on matching electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The CDEP147NP-8R0MC-125 qualifies as a direct substitute based on the following alignment of critical parameters:

Electrical Equivalence:

• Inductance value matches at 8 µH with identical ±20% tolerance
• DC resistance specification is identical at 7.8 mOhm maximum
• Saturation current matches at 10 A
• Current rating of 11 A meets the minimum requirement (main part rated 11.5 A)
• Operating temperature range is identical: -40°C to 125°C
• Inductance test frequency matches at 100 kHz

Mechanical Compatibility:

• Both components are surface mount, nonstandard package types
• Physical dimensions are comparable (main part: 15.00mm × 14.90mm × 8.10mm max height; substitute: 14.50mm × 14.50mm × 8.00mm max height)
• Both use Tape & Reel packaging for automated assembly

Regulatory Alignment:

• Both are ROHS3 compliant
• Both carry EAR99 ECCN classification
• Moisture sensitivity level is identical at MSL 1 (Unlimited)

The substitute differs only in core material composition (Sumida uses ferrite drum core wirewound construction versus Signal Transformer's unspecified core type) and manufacturer, but these differences do not affect the specified electrical performance or mechanical interface.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SCEP147L-8R0): The SCEP147L-8R0 is the specified component and should be used when available. It carries Active product status and full ROHS3 compliance with 945 units currently in stock, ensuring supply continuity for immediate procurement needs.

Substitute Part Selection (CDEP147NP-8R0MC-125): The CDEP147NP-8R0MC-125 is functionally equivalent and appropriate for use when the primary part is unavailable. This substitute maintains all critical electrical specifications and regulatory certifications. The current rating differential (11 A versus 11.5 A) is acceptable in applications where the design margin permits operation at the lower rating. With 1,384 units in stock, this substitute offers superior availability. Both parts are ROHS3 compliant and carry identical moisture sensitivity and export classification ratings.

Selection Criteria:

• Use SCEP147L-8R0 as the first choice when available
• Use CDEP147NP-8R0MC-125 when supply constraints require substitution
• Verify circuit design accommodates the 11 A current rating of the substitute
• Confirm PCB layout compatibility with the slightly smaller physical dimensions of the substitute (14.50mm × 14.50mm versus 15.00mm × 14.90mm)

Frequently Asked Questions (FAQ)

Q: Can CDEP147NP-8R0MC-125 be used as a direct replacement for SCEP147L-8R0?

A: Yes. Both parts meet the same electrical specifications for inductance (8 µH ±20%), DC resistance (7.8 mOhm max), saturation current (10 A), and operating temperature range (-40°C to 125°C). Both are shielded surface mount components with identical packaging format (Tape & Reel) and regulatory compliance (ROHS3). The substitute's current rating of 11 A is slightly lower than the main part's 11.5 A rating; verify your circuit design operates within this limit.

Q: What is the difference in physical size between these parts?

A: The main part (SCEP147L-8R0) measures 15.00mm × 14.90mm with a maximum seated height of 8.10mm. The substitute (CDEP147NP-8R0MC-125) measures 14.50mm × 14.50mm with a maximum seated height of 8.00mm. Both are nonstandard package types. Confirm your PCB layout accommodates the substitute's slightly smaller footprint.

Q: Are both parts RoHS compliant?

A: Yes. Both SCEP147L-8R0 and CDEP147NP-8R0MC-125 are ROHS3 compliant. Both carry identical Moisture Sensitivity Level (MSL 1 - Unlimited) and export classification (EAR99).

Q: What is the core material difference between these inductors?

A: The SCEP147L-8R0 core material is not specified in the technical data. The CDEP147NP-8R0MC-125 uses a ferrite drum core with wirewound construction. This material difference does not affect the specified electrical performance or mechanical interface.

Q: Which part should I specify in my design?

A: Specify SCEP147L-8R0 as the primary component. List CDEP147NP-8R0MC-125 as an approved substitute for procurement flexibility. Both parts deliver equivalent performance within the specified electrical and environmental parameters.

Q: Is the 0.5 A current rating difference significant?

A: The substitute's 11 A rating versus the main part's 11.5 A rating represents a 4.3% reduction in continuous current capacity. This difference is acceptable if your circuit design operates below 11 A. If your application requires the full 11.5 A rating, use the primary part (SCEP147L-8R0).
