CDR63BNP-560LC Equivalent & Substitute Parts

Part Overview

The CDR63BNP-560LC is a 56 µH shielded surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 460 mA continuous current with a maximum DC resistance of 720mOhm and operates across the temperature range of -40°C to 100°C. The part is classified as obsolete, making identification of suitable equivalent components necessary for ongoing design support, legacy system maintenance, and production continuity. Substitute parts must maintain the core electrical specifications while accommodating available alternatives in the current market.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR63BNP-560LC is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 56 µH (exact match required)
• Shielding type: Shielded (electromagnetic containment requirement)
• Mounting configuration: Surface Mount (PCB assembly compatibility)
• Operating temperature range: -40°C to 100°C minimum (thermal envelope)
• RoHS3 compliance: Required for regulatory alignment

Secondary Compatibility Parameters:

• Current rating: Minimum 460 mA (load capacity)
• DC resistance: Maximum 720mOhm (power dissipation and circuit performance)
• Package form factor: Nonstandard surface mount footprint (physical fit)

The CDRH5D28NP-560NC qualifies as a direct substitute based on matching inductance, shielding, surface mount configuration, temperature range, and RoHS3 compliance. This part is currently in active production status, ensuring supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The CDRH5D28NP-560NC is qualified as a direct substitute for the obsolete CDR63BNP-560LC based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains the required 56 µH inductance value and shielded configuration. The current rating of 580 mA exceeds the original 460 mA specification, providing operational margin. The DC resistance of 305 mOhm is significantly lower than the 720 mOhm maximum of the original part, resulting in reduced power dissipation and improved thermal performance in the circuit.

Regulatory and Environmental Compliance: Both parts carry ROHS3 compliance certification and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards. The operating temperature range of -40°C to 100°C is identical, maintaining thermal envelope requirements.

Production and Supply Status: The CDRH5D28NP-560NC is in active production status with 906 units currently in stock, ensuring reliable supply chain availability. The original CDR63BNP-560LC is obsolete, making this substitute the appropriate choice for new designs and legacy system support.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which differs from the original nonstandard packaging. This format is standard for high-volume surface mount assembly operations and is compatible with automated pick-and-place equipment.

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D28NP-560NC directly replace the CDR63BNP-560LC in existing designs?

A: Yes. Both parts share identical inductance (56 µH), shielding type (shielded), mounting configuration (surface mount), and operating temperature range (-40°C to 100°C). The substitute meets or exceeds all critical electrical parameters. Physical footprint compatibility should be verified against the specific PCB layout, as both parts use nonstandard surface mount packages.

Q: What is the impact of the wider tolerance (±30% vs ±15%) on circuit performance?

A: The CDRH5D28NP-560NC has a tolerance of ±30% compared to the original ±15%. This wider tolerance may affect circuits with tight inductance specifications. Applications requiring precise inductance control should evaluate whether the tolerance range remains acceptable for the intended function.

Q: Why is the DC resistance of the substitute lower (305 mOhm vs 720 mOhm)?

A: The lower DC resistance in the CDRH5D28NP-560NC results from improved core material and winding design in the newer part. This reduction decreases power dissipation and heat generation, providing a performance advantage in most applications. Circuits designed around the original 720 mOhm specification will experience improved efficiency with the substitute.

Q: Are there packaging implications when switching from the original to the substitute?

A: The original CDR63BNP-560LC uses nonstandard packaging, while the CDRH5D28NP-560NC is supplied in standard Tape & Reel (TR) format. Tape & Reel packaging is compatible with automated assembly equipment and is the industry standard for surface mount components. Procurement and assembly processes may require adjustment to accommodate this standard packaging format.

Q: Is the substitute part suitable for high-reliability applications?

A: Both parts carry ROHS3 compliance and MSL Level 1 ratings. The substitute is in active production status, indicating ongoing manufacturer support and quality control. For applications requiring specific reliability certifications or qualification testing, those requirements should be verified against the substitute part's documentation.

Q: What is the current inventory status for the substitute part?

A: The CDRH5D28NP-560NC has 906 units currently in stock as new original inventory. The original CDR63BNP-560LC has 1021 units available but is classified as obsolete with no ongoing production.
