SCEP147L-100 Equivalent & Substitute Parts

Part Overview

The SCEP147L-100 is a 10 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring high current handling and low DC resistance. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or application-specific packaging needs.

Key Parameters

Substitute Part Grouping Explanation

The CDEP147NP-100MC-125 manufactured by Sumida America Components Inc. qualifies as an equivalent substitute based on the following critical parameters:

Inductance value matches at 10 µH with identical ±20% tolerance. Current rating of 10 A is within acceptable operating range relative to the primary part's 10.2 A specification. DC resistance is identical at 9.85 mOhm maximum. Saturation current matches at 9.2 A. Both components feature shielded construction, identical operating temperature range (-40°C ~ 125°C), and equivalent inductance test frequency of 100 kHz. Both are RoHS3 compliant with MSL rating of 1 (Unlimited). Surface mount configuration and nonstandard package classification are consistent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both SCEP147L-100 and CDEP147NP-100MC-125 are Active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging requirements and dimensional constraints. The SCEP147L-100 is supplied in Tape & Reel format, while the CDEP147NP-100MC-125 is available in Cut Tape and Digi-Reel packaging options. Dimensional differences are minor: the Sumida part is slightly smaller in footprint (14.50mm x 14.50mm versus 15.00mm x 14.90mm) and marginally lower in seated height (8.00mm versus 8.10mm). Current rating differential of 0.2 A is negligible for applications operating below 10 A continuous load.

Frequently Asked Questions (FAQ)

Q: Can CDEP147NP-100MC-125 directly replace SCEP147L-100 in existing designs?

A: Yes. Both components share identical inductance (10 µH), tolerance (±20%), DC resistance (9.85 mOhm max), saturation current (9.2 A), operating temperature range (-40°C ~ 125°C), and shielding characteristics. The 0.2 A current rating difference is not a limiting factor for standard applications. Dimensional variations are minor and typically accommodated within standard PCB layout tolerances.

Q: What are the packaging differences between these parts?

A: SCEP147L-100 is supplied in Tape & Reel (TR) format. CDEP147NP-100MC-125 is available in Cut Tape (CT) and Digi-Reel® packaging. Selection depends on assembly line equipment compatibility and procurement volume requirements.

Q: Are both parts compliant with current regulatory standards?

A: Both components are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts, indicating no special storage or handling requirements.

Q: What is the significance of the 0.2 A current rating difference?

A: The SCEP147L-100 is rated at 10.2 A while CDEP147NP-100MC-125 is rated at 10 A. Both share identical saturation current of 9.2 A. This minor difference does not affect substitution suitability for applications operating within standard design margins below 10 A continuous current.

Q: Do dimensional differences affect PCB layout compatibility?

A: Dimensional variations are minimal. CDEP147NP-100MC-125 footprint is 0.571" x 0.571" (14.50mm x 14.50mm) versus SCEP147L-100 at 0.591" x 0.587" (15.00mm x 14.90mm). Height difference is 0.004" (0.10mm). These variations are typically within standard PCB design tolerances and do not require layout modifications for standard applications.
