CDV16FF681JO3 Mica Capacitor - Equivalent & Substitute Parts

Part Overview

The CDV16FF681JO3 is a 680 pF mica capacitor rated for 1 kV with ±5% tolerance, designed for through-hole radial mounting in RF and high-Q applications. This component is currently active in production. Alternative models become necessary when addressing RoHS compliance requirements or when inventory constraints necessitate functional equivalents that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the CDV16FF681JO3 is determined by maintaining identical electrical and mechanical parameters across the following critical specifications:

• Capacitance Value: 680 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 1 kV (minimum requirement; higher ratings acceptable)
• Dielectric Material: Mica (mandatory for RF and high-Q performance characteristics)
• Operating Temperature Range: -55°C to 150°C (exact match required)
• Mounting Configuration: Through-hole radial (exact match required)
• Lead Spacing: 0.232" (5.90mm) (exact match required for PCB compatibility)
• Package Dimensions: 0.461" L x 0.173" W, Height 0.500" max (exact match required)

The CDV16FF681JO3F variant qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

Selection between CDV16FF681JO3 and CDV16FF681JO3F depends on compliance requirements:

CDV16FF681JO3F is the preferred selection for applications requiring RoHS3 compliance or REACH unaffected status. This variant maintains identical electrical performance and mechanical compatibility while eliminating compliance constraints associated with the non-compliant version.

CDV16FF681JO3 remains suitable for applications where RoHS compliance is not mandated and REACH-affected materials are acceptable. Both variants are active in production and functionally interchangeable in circuits where regulatory compliance is not a specification requirement.

Frequently Asked Questions (FAQ)

Q: Are CDV16FF681JO3 and CDV16FF681JO3F electrically identical? A: Yes. Both parts feature identical capacitance (680 pF), tolerance (±5%), voltage rating (1 kV), dielectric material (mica), and operating temperature range (-55°C to 150°C).

Q: Can CDV16FF681JO3F be used as a drop-in replacement for CDV16FF681JO3? A: Yes. The substitute part has identical lead spacing (0.232" / 5.90mm), package dimensions (0.461" L x 0.173" W), and mounting configuration. No PCB layout modifications are required.

Q: What is the primary difference between these two part numbers? A: The CDV16FF681JO3F is RoHS3 compliant and REACH unaffected, while the CDV16FF681JO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which variant should I specify for new designs? A: Selection depends on design compliance requirements. If RoHS3 compliance or REACH unaffected status is mandatory, specify CDV16FF681JO3F. If compliance is not required, either part is suitable.

Q: Is inventory a factor in substitution decision? A: CDV16FF681JO3F has greater available inventory (2172 pieces versus 908 pieces), which may influence supply chain decisions independent of technical compatibility.
