CD15FC681JO3 Mica Capacitor 680 pF 300 V Radial

Part Overview

The CD15FC681JO3 is a 680 pF mica capacitor rated for 300 V operation in a radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component belongs to the CD15 series and is classified as active in product status. Mica capacitors serve critical functions in RF, analog, and high-reliability circuit applications requiring stable capacitance values and low dielectric loss. Alternative part sourcing becomes necessary when managing inventory constraints, addressing supply chain variability, or accommodating design revision requirements across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FC681JO3 is determined by strict electrical and mechanical parameter matching within the CD15 series mica capacitor family. The following parameters define acceptable substitutes:

• Capacitance Value: 680 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 300 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.232" (5.90 mm) (exact match required)
• Physical Dimensions: 0.469" L × 0.209" W × 0.390" H maximum (exact match required)

The substitute part CD15FC681JO3F maintains complete electrical and mechanical compatibility with the primary part number, differing only in regulatory compliance status and manufacturing batch traceability designations.

Parameter Comparison

Engineering Selection Recommendations

Both the CD15FC681JO3 and CD15FC681JO3F are active product offerings from Cornell Dubilier Electronics with identical electrical performance and mechanical compatibility. Selection between these parts should be driven by regulatory and compliance requirements specific to the application:

CD15FC681JO3 is appropriate for applications without RoHS compliance mandates or where non-compliant component sourcing is acceptable within the design framework.

CD15FC681JO3F is specified for designs requiring RoHS3 compliance certification and for applications subject to REACH compliance restrictions where REACH Unaffected status is mandatory. This variant eliminates restricted substance concerns in regulated supply chains.

Both parts share equivalent electrical specifications, physical dimensions, lead spacing, and temperature performance characteristics, ensuring direct functional interchangeability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are CD15FC681JO3 and CD15FC681JO3F electrically identical? A: Yes. Both parts deliver identical capacitance (680 pF ± 5%), voltage rating (300 V), temperature stability (-55°C to 125°C), and frequency characteristics as mica dielectric capacitors in the CD15 series.

Q: What is the primary difference between these two part numbers? A: The primary difference is regulatory compliance status. CD15FC681JO3F is RoHS3 Compliant and REACH Unaffected, while the original CD15FC681JO3 carries RoHS non-compliant and REACH Affected designations.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. Both parts feature identical physical dimensions, lead spacing (0.232" / 5.90 mm), and radial through-hole package configuration, enabling direct mechanical and electrical interchangeability without layout modifications.

Q: Which part should I specify for new designs? A: For new product development, specify CD15FC681JO3F to ensure compliance with current RoHS3 and REACH regulatory requirements applicable to commercial and industrial applications.

Q: Are there any thermal or frequency performance differences between these substitutes? A: No. Both parts share the identical operating temperature range (-55°C to 125°C) and mica dielectric composition, delivering equivalent frequency response and thermal stability characteristics across their rated temperature envelope.

Q: What inventory availability exists for each part? A: CD15FC681JO3 has 1122 pieces in stock, while CD15FC681JO3F has 1072 pieces in stock, both available as new original components.
