Substitute Part Grouping Explanation

Substitution eligibility for the SCEP147S-7R7 is determined by strict equivalence across the following critical parameters:

• Inductance value: 7.7 µH at ±20% tolerance
• Current rating: 10 A minimum continuous rating
• Saturation current: 12.4 A minimum
• DC resistance: 9.85 mOhm maximum
• Shielding requirement: Shielded construction
• Operating temperature range: -40°C to 125°C minimum
• Surface mount configuration with nonstandard package dimensions
• RoHS3 compliance and MSL 1 rating

The CDEP147NP-7R7MC-95 manufactured by Sumida America Components Inc. meets all specified electrical and mechanical parameters, enabling direct substitution in applications requiring the SCEP147S-7R7.

Parameter Comparison

Engineering Selection Recommendations

Both the SCEP147S-7R7 and CDEP147NP-7R7MC-95 are active production components with full ROHS3 compliance and MSL 1 rating. The SCEP147S-7R7 is currently available with 704 units in stock. The CDEP147NP-7R7MC-95 offers higher inventory availability at 7,318 units in stock and utilizes a drum core, wirewound construction with ferrite core material. Selection between these parts should be based on supply chain requirements, lead time considerations, and inventory availability for the application timeline.

Frequently Asked Questions (FAQ)

Q: Can the CDEP147NP-7R7MC-95 be used as a direct replacement for the SCEP147S-7R7?

A: Yes. Both parts meet identical electrical specifications including 7.7 µH inductance at ±20% tolerance, 10 A current rating, 12.4 A saturation current, and 9.85 mOhm maximum DC resistance. Both are shielded surface mount inductors with identical operating temperature ranges and compliance certifications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The SCEP147S-7R7 measures 0.591" L × 0.587" W × 0.319" H (15.00mm × 14.90mm × 8.10mm). The CDEP147NP-7R7MC-95 measures 0.571" L × 0.571" W × 0.315" H (14.50mm × 14.50mm × 8.00mm). Both use nonstandard packages and surface mount configuration. PCB layout verification is necessary to confirm mechanical fit.

Q: What is the difference in core material construction?

A: The SCEP147S-7R7 core material is not specified in the product data. The CDEP147NP-7R7MC-95 uses a ferrite drum core with wirewound construction. Both achieve identical electrical performance at the specified test frequency of 100 kHz.

Q: Are both parts RoHS compliant?

A: Yes. The SCEP147S-7R7 is ROHS3 compliant. The CDEP147NP-7R7MC-95 is ROHS3 compliant. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected based on availability?

A: The CDEP147NP-7R7MC-95 has significantly higher inventory at 7,318 units compared to 704 units for the SCEP147S-7R7. Selection should align with supply chain and production schedule requirements.
