Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified based on strict equivalence of electrical and mechanical parameters. The CDV30FH431JO3F substitute list includes components that maintain identical specifications across all critical parameters: capacitance value (430 pF), tolerance (±5%), voltage rating (1.5 kV), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), and package configuration (radial).

Substitution eligibility is determined by the following key parameters:

• Capacitance: 430 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1.5 kV (exact match required)
• Dielectric: Mica (exact match required)
• Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting: Through Hole (exact match required)
• Package: Radial (exact match required)

Variations in regulatory compliance status (RoHS, REACH) and inventory levels do not affect electrical or mechanical substitutability but may influence procurement decisions based on application requirements and supply chain constraints.

Parameter Comparison

Engineering Selection Recommendations

The CDV30FH431JO3F and CDV30FH431JO3F+XZX are electrically and mechanically equivalent components. Selection between these parts should be based on regulatory and compliance requirements specific to the application.

For applications requiring RoHS3 compliance: The CDV30FH431JO3F is the appropriate selection, as it meets ROHS3 Compliant status and REACH Unaffected designation.

For applications where RoHS compliance is not a requirement: The CDV30FH431JO3F+XZX provides an alternative source with identical electrical and mechanical specifications. This part is RoHS non-compliant and REACH Affected.

Both components share identical electrical performance characteristics, temperature stability, voltage rating, and physical form factor. Inventory availability should be considered as a secondary factor in component selection, with 980 units of the main part and 819 units of the substitute currently available.

Frequently Asked Questions (FAQ)

Q: Can CDV30FH431JO3F+XZX be used as a direct replacement for CDV30FH431JO3F?

A: Yes, from an electrical and mechanical standpoint. Both components have identical capacitance (430 pF), tolerance (±5%), voltage rating (1.5 kV), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), and radial package configuration. The primary difference is regulatory compliance status. Verify that your application does not require RoHS3 or REACH compliance before substituting.

Q: What is the difference between the two part numbers?

A: The suffix "+XZX" on CDV30FH431JO3F+XZX indicates a variant designation. The electrical and mechanical specifications remain identical to the base CDV30FH431JO3F. The regulatory compliance differs: the main part is ROHS3 Compliant and REACH Unaffected, while the variant is RoHS non-compliant and REACH Affected.

Q: Are there any physical dimension differences between these parts?

A: No. Both components are through-hole radial mica capacitors from the CDV30 series with identical package configurations. Physical mounting and PCB layout compatibility is maintained.

Q: Which part should I specify for a new design?

A: Specify CDV30FH431JO3F if your application or market requires RoHS3 compliance or REACH compliance. This ensures regulatory alignment and future supply chain compatibility. Use CDV30FH431JO3F+XZX only when compliance requirements do not apply to your specific application.

Q: Can I mix these parts in the same production batch?

A: Electrically and mechanically, yes. However, mixing parts with different compliance statuses may create documentation and traceability issues. Maintain consistent part selection within a single design revision or production lot.

Q: What is the temperature stability of these capacitors?

A: Both parts operate across -55°C to 125°C with mica dielectric material, which provides stable capacitance characteristics across this temperature range. Mica capacitors exhibit minimal capacitance drift over temperature.
