Substitute Part Grouping Explanation

Substitution eligibility for the CDV19FF681JO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 680 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Lead Spacing: 0.343" / 8.70mm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Series: CDV19 (exact match required)

The identified substitute part CDV19FF681JO3F maintains full electrical and mechanical equivalence across all specified parameters. Both components are manufactured within the same product series and share identical form factors, allowing direct interchange in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CDV19FF681JO3 and CDV19FF681JO3F are Active products suitable for component selection. The primary differentiation between these parts lies in regulatory compliance status. The CDV19FF681JO3F variant achieves ROHS3 compliance and carries REACH Unaffected designation, making it the preferred choice for new designs or applications subject to EU environmental directives. The original CDV19FF681JO3 remains applicable in applications without such compliance requirements. Inventory availability shows 1264 pcs for the CDV19FF681JO3F versus 865 pcs for the CDV19FF681JO3, providing supply flexibility.

Frequently Asked Questions (FAQ)

Q: Can CDV19FF681JO3F be used in place of CDV19FF681JO3? A: Yes. Both parts are electrically and mechanically equivalent, sharing identical capacitance, voltage rating, tolerance, dielectric material, and physical dimensions. Direct substitution is permissible in all circuit applications.

Q: What is the difference between these two part numbers? A: The primary difference is regulatory compliance. CDV19FF681JO3F is ROHS3 compliant and REACH Unaffected, while CDV19FF681JO3 is RoHS non-compliant and REACH Affected. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.661" L x 0.220" W with a maximum seated height of 0.520", and both feature 0.343" lead spacing. PCB layout modifications are not required when substituting between these parts.

Q: Which part should be specified for new designs? A: Selection depends on applicable compliance requirements. For designs subject to RoHS3 or REACH regulations, CDV19FF681JO3F is the appropriate choice. For applications without such mandates, either part is acceptable based on availability and cost considerations.

Q: What is the operating temperature range for both parts? A: Both parts operate over the range of -55°C to 125°C, supporting identical thermal application requirements.

Q: Are lead times or availability different between these parts? A: Current inventory shows 1264 pcs of CDV19FF681JO3F in stock compared to 865 pcs of CDV19FF681JO3, offering greater immediate availability for the F variant.
