Substitute Part Grouping Explanation

Substitution eligibility for the CD19FD471FO3F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (470 pF), tolerance specification (±1%), and voltage rating (500 V) must be identical. The mica dielectric material is a defining characteristic of this component class and cannot be substituted with alternative dielectric types.

Mechanical Parameters: Mounting configuration (through-hole radial), lead spacing (0.343" / 8.70 mm), and physical envelope dimensions must match to ensure PCB compatibility without redesign.

Thermal Parameters: Operating temperature range (-55°C to 125°C) establishes the functional operating window and must be maintained.

Series Designation: Both the main part and substitute parts belong to the CD19 series, confirming design family consistency.

The identified substitute CD19FD471FO3 shares identical electrical and mechanical specifications with the main part, differing only in regulatory compliance status and inventory availability.

Engineering Selection Recommendations

Primary Selection (CD19FD471FO3F): This part is the preferred choice for applications subject to RoHS3 compliance requirements or REACH-regulated supply chains. Active product status with established inventory ensures supply continuity. The ROHS3 compliant designation and REACH Unaffected status make this part suitable for consumer electronics, industrial equipment, and regulated markets.

Substitute Selection (CD19FD471FO3): The CD19FD471FO3 provides electrical and mechanical equivalence with identical performance characteristics. This part is suitable for applications where RoHS3 compliance is not mandated and REACH restrictions do not apply. Higher current inventory (1360 units) may provide supply advantage in time-sensitive procurement scenarios. Selection of this substitute requires confirmation that end-use application and market regulations do not impose RoHS3 or REACH compliance obligations.

Compliance Verification: Design engineers must confirm regulatory requirements applicable to the end application before selecting between these parts. RoHS3 compliance is mandatory for products marketed in the European Union and certain other jurisdictions. REACH compliance affects supply chain documentation and material sourcing.

Frequently Asked Questions (FAQ)

Q: Are CD19FD471FO3F and CD19FD471FO3 electrically identical?

A: Yes. Both parts have identical capacitance (470 pF), tolerance (±1%), voltage rating (500 V), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from a mechanical and electrical standpoint. Both parts have identical lead spacing (0.343" / 8.70 mm), radial package configuration, and physical dimensions. PCB layout compatibility is maintained.

Q: What is the difference between these two parts?

A: The primary differences are regulatory compliance status and inventory levels. CD19FD471FO3F is ROHS3 compliant and REACH Unaffected, while CD19FD471FO3 is RoHS non-compliant and REACH Affected. Inventory for CD19FD471FO3 is higher (1360 units vs. 1182 units).

Q: Which part should I specify for a consumer electronics application?

A: Specify CD19FD471FO3F if the product will be sold in the European Union or regions with RoHS3 requirements. The ROHS3 compliant designation ensures regulatory compliance.

Q: Can I substitute CD19FD471FO3 for CD19FD471FO3F in an existing design?

A: Substitution is technically feasible from an electrical and mechanical perspective. However, regulatory compliance must be evaluated. If the application requires RoHS3 compliance, CD19FD471FO3 is not suitable. Confirm compliance requirements before making this substitution.

Q: What does "REACH Unaffected" mean?

A: REACH Unaffected indicates the part does not contain substances of very high concern (SVHC) listed under the EU REACH regulation. This status simplifies supply chain documentation and regulatory compliance for European markets.

Q: Are both parts currently in production?

A: Yes. Both parts maintain Active product status, indicating ongoing manufacturing and availability through authorized distributors.
