Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRH4D14R-560 is based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 56 µH (exact match required)
• Inductance tolerance: ±30% (matching tolerance band)
• Shielding type: Shielded (electromagnetic containment requirement)
• Mounting type: Surface Mount (assembly compatibility)
• Inductance test frequency: 100 kHz (measurement standard alignment)

Secondary Compatibility Factors:

• Current rating must equal or exceed 370 mA
• DC resistance must not exceed 1.8 Ohm
• Operating temperature range must cover -40°C to 125°C or be compatible with application requirements
• RoHS3 compliance status
• Physical dimensions and height constraints for PCB layout

The CDRH3D28/LDNP-560NC from Sumida America Components Inc. meets all primary matching criteria and exceeds performance specifications in current rating and DC resistance, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CDRH3D28/LDNP-560NC is a direct functional substitute for the obsolete SCRH4D14R-560. Both components share identical inductance values, tolerance specifications, and shielding characteristics. The substitute part demonstrates superior electrical performance with a current rating of 760 mA (double the original specification) and significantly lower DC resistance of 325 mOhm compared to 1.8 Ohm.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility. The substitute part is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete original part.

Physical dimensions differ slightly: the substitute is marginally smaller in footprint (3.80mm vs 4.10mm) but taller in seated height (3.00mm vs 1.50mm). PCB layout verification is required to confirm height clearance compatibility with the application.

The operating temperature range of the substitute extends to 105°C versus 125°C for the original part. Applications requiring operation above 105°C must evaluate thermal requirements against the substitute's specifications.

Frequently Asked Questions (FAQ)

Q: Can the CDRH3D28/LDNP-560NC directly replace the SCRH4D14R-560 in existing designs?

A: Yes, for applications operating within -40°C to 105°C. Both parts share identical inductance (56 µH), tolerance (±30%), and shielding characteristics. The substitute provides superior current handling (760 mA vs 370 mA) and lower DC resistance (325 mOhm vs 1.8 Ohm). PCB layout must accommodate the increased seated height (3.00mm vs 1.50mm).

Q: What are the key electrical differences between these parts?

A: The substitute part exceeds the original in current rating and DC resistance performance. Saturation current is comparable (200 mA vs 210 mA). The primary trade-off is operating temperature range: the substitute is rated to 105°C versus 125°C for the original part.

Q: Are there packaging or handling differences?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, requiring identical storage and handling protocols. The substitute is supplied in Tape & Reel packaging versus the original's unspecified packaging format. Both maintain ROHS3 compliance.

Q: How do physical dimensions affect PCB integration?

A: The substitute footprint is slightly smaller (3.80mm x 3.80mm vs 4.10mm x 4.10mm), providing minor space savings. However, seated height increases from 1.50mm to 3.00mm, potentially affecting clearance with adjacent components or shielding structures. PCB layout review is necessary before implementation.

Q: What is the substitution basis for these parts?

A: Substitution is based on matching inductance value (56 µH), tolerance band (±30%), shielding type (Shielded), mounting method (Surface Mount), and test frequency (100 kHz). The substitute meets or exceeds all electrical performance requirements of the original part.
