Substitute Part Grouping Explanation

Substitute parts for the CDRH4D22NP-680NC are qualified based on the following critical parameters:

Electrical Compatibility Criteria:

• Inductance value: 68 µH (matching nominal specification)
• Inductance tolerance: ±30% (matching tolerance band)
• Current rating: minimum 630 mA (substitute must support primary component current requirements)
• DC resistance: maximum 400 mOhm to 634.1 mOhm (lower DCR values are acceptable as they represent improved performance)
• Saturation current: minimum 330 mA (substitute must not saturate below primary component saturation point)
• Core material: Ferrite (consistent electromagnetic properties)
• Shielding: Shielded (maintains EMI containment)

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount (identical assembly process)
• Package footprint: 4.70 mm × 4.70 mm to 4.80 mm × 4.80 mm (within acceptable PCB layout tolerance)
• Height: 2.40 mm to 3.00 mm (accommodates standard assembly clearances)

Environmental & Compliance Criteria:

• Operating temperature range: -40°C minimum to 100°C minimum (substitute must cover or exceed primary range)
• RoHS3 compliance: required
• Moisture sensitivity: MSL 1 (unlimited exposure)

The substitute SRR4028-680Y meets all electrical and mechanical criteria while providing equivalent functional performance in the specified application space.

Parameter Comparison

Engineering Selection Recommendations

Primary Component Selection: The CDRH4D22NP-680NC remains the preferred component when available. It is Active product status with ROHS3 compliance and MSL 1 rating, confirming current manufacturing support and environmental regulatory adherence.

Substitute Component Selection: The SRR4028-680Y (Bourns Inc.) is qualified as a direct substitute when CDRH4D22NP-680NC availability is constrained. The substitute maintains identical inductance, tolerance, core material, shielding, and mounting type. Both components are Active status with ROHS3 compliance.

Performance Considerations: The SRR4028-680Y provides measurable performance improvements: 37% lower DC resistance (400 mOhm vs. 634.1 mOhm maximum) and higher saturation current (360 mA vs. 330 mA). These characteristics result in reduced power dissipation and improved current handling margin. The extended operating temperature range (-40°C to 125°C vs. -40°C to 100°C) provides additional thermal headroom.

Physical Considerations: The substitute component is 0.60 mm taller (3.00 mm vs. 2.40 mm seated height) and 0.10 mm larger in footprint dimensions (4.80 mm vs. 4.70 mm). Verify PCB assembly clearances and component placement constraints before substitution in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can SRR4028-680Y be used as a direct replacement for CDRH4D22NP-680NC in all applications?

A: The SRR4028-680Y is electrically compatible as a substitute. Both components share identical inductance (68 µH), tolerance (±30%), core material (ferrite), and shielding. Mechanical compatibility requires verification of PCB clearance for the 0.60 mm height difference and 0.10 mm footprint increase. Confirm assembly process compatibility with your manufacturing partner.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The SRR4028-680Y exhibits 400 mOhm maximum DCR compared to 634.1 mOhm maximum for the CDRH4D22NP-680NC. Lower DC resistance reduces I²R power dissipation in the inductor, resulting in lower operating temperature and improved efficiency. This is a performance advantage in current-carrying applications.

Q: Does the higher saturation current of the substitute part affect circuit behavior?

A: The SRR4028-680Y saturation current is 360 mA versus 330 mA for the primary component. Higher saturation current provides additional margin before inductance degradation occurs. This represents improved performance and does not negatively affect circuit operation when the primary component's saturation specification is met.

Q: Are there packaging differences between these components?

A: The CDRH4D22NP-680NC is supplied in Tape & Reel (TR) packaging. The SRR4028-680Y is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount compatible. Verify packaging format compatibility with your procurement and assembly processes.

Q: What compliance certifications apply to both components?

A: Both CDRH4D22NP-680NC and SRR4028-680Y are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) ratings. Both are classified as Active product status, confirming current manufacturing support and regulatory compliance.

Q: Can the substitute part be used in high-temperature applications?

A: The SRR4028-680Y operates to 125°C maximum, exceeding the CDRH4D22NP-680NC specification of 100°C. If your application requires operation above 100°C, the substitute component provides extended thermal capability. Verify that all other circuit components support the higher temperature range.
