Key Parameters

Substitute Part Grouping Explanation

The CDRH104RNP-7R0NC from Sumida America Components Inc. qualifies as a direct substitute based on the following critical parameters:

• Identical inductance value: 7 µH with ±30% tolerance
• Equivalent DC resistance specification: 27 mOhm Max
• Matching saturation current: 4.8 A
• Identical shielding classification: Shielded
• Identical mounting technology: Surface Mount
• Equivalent package classification: Nonstandard
• Matching inductance test frequency: 100 kHz
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

The substitute part demonstrates functional equivalence across all specified electrical parameters. Physical dimensions show minor variation within acceptable tolerances for the nonstandard package category.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH104R-7R0 and CDRH104RNP-7R0NC are active production components with full RoHS3 compliance and identical moisture sensitivity ratings. The substitute part is suitable for applications operating within the -40°C to 100°C temperature range. For applications requiring operation above 100°C, the original SCRH104R-7R0 with its extended -40°C to 125°C range must be retained. The continuous current rating difference of 0.09 A (4.59 A versus 4.5 A) is negligible for most circuit designs given the identical saturation current specification of 4.8 A. Physical dimensions are compatible within standard PCB layout tolerances for nonstandard package inductors.

Frequently Asked Questions (FAQ)

Q: Can CDRH104RNP-7R0NC be used as a direct replacement for SCRH104R-7R0 in all applications?

A: The substitute part is functionally equivalent for applications operating within -40°C to 100°C. Applications requiring sustained operation above 100°C must use the original SCRH104R-7R0 due to its extended temperature rating to 125°C.

Q: What is the significance of the 0.09 A difference in continuous current rating?

A: Both parts share an identical saturation current of 4.8 A. The continuous current rating difference reflects manufacturer specifications but does not affect circuit compatibility for standard applications, as saturation current determines the absolute current limit.

Q: Are the physical dimension differences between the two parts significant?

A: The substitute part is 0.30mm shorter in length and 0.30mm narrower in width. Both maintain identical 4.00mm maximum seated height. These minor variations are within standard PCB layout tolerances for nonstandard package components and do not affect footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SCRH104R-7R0 and CDRH104RNP-7R0NC are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: What is the inductance tolerance for both parts?

A: Both parts are specified with ±30% inductance tolerance at 100 kHz test frequency, ensuring equivalent performance characteristics across the specified tolerance band.
