Substitute Part Grouping Explanation

Substitution of the CDV19FF121JO3 is determined by strict equivalence across the following parameters:

• Capacitance Value: 120 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.343" (8.70mm) (exact match required)
• Physical Dimensions: 0.642" L x 0.189" W, Height 0.500" max (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The CDV19FF121JO3F qualifies as a direct substitute based on identical electrical and mechanical specifications. Differences in regulatory compliance status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

CDV19FF121JO3: Select this part number for applications where RoHS non-compliance is acceptable or where legacy system compatibility is required. Current inventory: 1001 pcs.

CDV19FF121JO3F: Select this part number for applications requiring ROHS3 compliance and REACH unaffected status. This variant meets modern regulatory requirements for new designs and procurement specifications. Current inventory: 1810 pcs.

Both part numbers are functionally equivalent across all electrical and mechanical parameters. Selection between them is determined by regulatory compliance requirements of the end application or procurement specification, not by technical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are CDV19FF121JO3 and CDV19FF121JO3F electrically identical?

A: Yes. Both parts have identical capacitance (120 pF), tolerance (±5%), voltage rating (1 kV), dielectric material (mica), and operating temperature range (-55°C ~ 125°C).

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.343" / 8.70mm), body dimensions (0.642" L x 0.189" W / 16.30mm x 4.80mm), and maximum seated height (0.500" / 12.70mm). They are pin-compatible and footprint-compatible.

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

A: The primary differences are regulatory compliance status. CDV19FF121JO3F is ROHS3 compliant and REACH unaffected, while CDV19FF121JO3 is RoHS non-compliant and REACH affected. Electrical and mechanical performance are identical.

Q: Can I use CDV19FF121JO3F as a direct replacement for CDV19FF121JO3?

A: Yes, for applications where ROHS3 compliance is acceptable or required. The parts are functionally and mechanically equivalent.

Q: Can I use CDV19FF121JO3 as a direct replacement for CDV19FF121JO3F?

A: Only if the application does not require ROHS3 compliance or REACH unaffected status. Electrical and mechanical compatibility is confirmed.

Q: What mounting considerations apply to both parts?

A: Both are through-hole radial components with identical lead spacing and body dimensions. They mount identically on PCBs with 0.343" (8.70mm) hole spacing.
