Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR63BNP-180MC is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 18 µH (exact match required)
• Shielding type: Shielded (electromagnetic containment requirement)
• Mounting technology: Surface Mount (PCB assembly compatibility)
• Operating temperature range: -40°C to 100°C (environmental specification)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Secondary Compatibility Parameters:

• Current rating: Substitute must equal or exceed 780 mA
• DC resistance: Substitute must not exceed 250mOhm maximum
• Package form factor: Nonstandard surface mount packages

The CDRH5D28NP-180NC satisfies all primary criteria and exceeds current rating specifications (1 A vs. 780 mA), providing enhanced performance margin. DC resistance is reduced to 110mOhm maximum, improving efficiency characteristics.

Engineering Selection Recommendations

The CDRH5D28NP-180NC is the qualified substitute for the obsolete CDR63BNP-180MC based on the following engineering factors:

Product Status Alignment: The substitute part maintains active product status with Sumida America Components Inc., ensuring long-term availability and supply chain continuity. The main part is classified as obsolete, making transition to an active equivalent necessary for production sustainability.

Electrical Specification Compliance: Both parts deliver 18 µH inductance with shielded construction and identical operating temperature ranges (-40°C to 100°C). The substitute exceeds the current rating requirement (1 A vs. 780 mA) and reduces DC resistance (110mOhm vs. 250mOhm maximum), delivering improved thermal and efficiency performance.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), satisfying environmental and manufacturing requirements without modification.

Physical Integration: The substitute features a smaller footprint (5.70 x 5.70 mm vs. 6.20 x 5.60 mm) and reduced height (3.00 mm vs. 3.50 mm seated), providing enhanced PCB layout flexibility. Packaging is supplied in standard Tape & Reel format, improving manufacturing efficiency compared to the nonstandard packaging of the main part.

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D28NP-180NC directly replace the CDR63BNP-180MC in existing designs?

A: Yes. Both parts share identical inductance (18 µH), shielding type, operating temperature range, and RoHS compliance. The substitute exceeds current rating and reduces DC resistance, providing enhanced performance margins. Physical dimensions are comparable with the substitute offering a smaller footprint.

Q: What is the significance of the inductance tolerance difference (±20% vs. ±30%)?

A: The main part specifies ±20% tolerance while the substitute specifies ±30%. For applications requiring tighter inductance control, the main part's tolerance is superior. However, both tolerances fall within standard industrial specifications for shielded inductors. Circuit design should account for the substitute's wider tolerance range if inductance precision is critical.

Q: How does the reduced DC resistance of the substitute affect circuit performance?

A: The substitute's 110mOhm maximum DCR compared to the main part's 250mOhm maximum represents a 56% reduction in resistive losses. This improvement reduces heat generation and improves power efficiency in current-carrying applications. The substitute's higher current rating (1 A vs. 780 mA) further enhances thermal performance margin.

Q: Are there packaging considerations for production transition?

A: The main part uses nonstandard packaging while the substitute is supplied in standard Tape & Reel (TR) format. This transition improves automated assembly compatibility and reduces handling complexity. Verify that existing pick-and-place equipment supports the substitute's package dimensions (5.70 x 5.70 x 3.00 mm).

Q: What is the core material composition of each part?

A: The main part's core material is not specified in available documentation. The substitute specifies ferrite core material, which is standard for shielded surface mount inductors in this inductance and current rating range.

Q: Is the substitute suitable for high-frequency applications?

A: The main part specifies a self-resonant frequency of 26.7 MHz. The substitute's self-resonant frequency is not specified in available data. For applications operating near or above 20 MHz, verify the substitute's frequency response characteristics with the manufacturer before implementation.
