• Capacitance Value: Exactly 620 pF
• Tolerance: ±5%
• Voltage Rating: 300 V minimum
• Dielectric Material: Mica
• Operating Temperature Range: -55°C to 125°C minimum
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.232" (5.90 mm)
• Physical Dimensions: 0.461" L x 0.209" W (11.70 mm x 5.30 mm)
• Maximum Seated Height: 0.382" (9.70 mm)
• Manufacturer: Cornell Dubilier Electronics (CDE)
• Series: CD15

The CD15FC621JO3F meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The CD15FC621JO3F serves as a direct parametric equivalent to the CD15FC621JO3 across all electrical and mechanical specifications. Both parts are manufactured by Cornell Dubilier Electronics within the CD15 series and maintain identical performance characteristics for capacitance, voltage rating, temperature range, and physical form factor.

The primary distinction between these parts lies in regulatory compliance status. The CD15FC621JO3F achieves ROHS3 compliance and REACH unaffected status, whereas the CD15FC621JO3 is classified as RoHS non-compliant and REACH affected. Selection between these parts should be determined by the regulatory requirements of the end application and target market.

From an inventory perspective, the CD15FC621JO3F maintains higher stock availability at 2518 units compared to 787 units for the CD15FC621JO3, supporting supply chain continuity objectives.

Frequently Asked Questions (FAQ)

Q: Can the CD15FC621JO3F be used as a direct replacement for the CD15FC621JO3?

A: Yes. The CD15FC621JO3F is electrically and mechanically identical to the CD15FC621JO3. Both parts share identical capacitance (620 pF), tolerance (±5%), voltage rating (300 V), operating temperature range (-55°C to 125°C), mounting configuration (through-hole radial), lead spacing (0.232" / 5.90 mm), and physical dimensions. Substitution is valid for all applications where the original part was specified.

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

A: The primary differences are regulatory compliance and inventory levels. The CD15FC621JO3F is ROHS3 compliant and REACH unaffected, while the CD15FC621JO3 is RoHS non-compliant and REACH affected. The CD15FC621JO3F also has higher inventory availability (2518 units versus 787 units).

Q: Are there any performance differences between CD15FC621JO3 and CD15FC621JO3F?

A: No. Both parts deliver identical electrical performance. Capacitance stability, voltage rating, temperature coefficient, and all other electrical characteristics are equivalent across the specified operating range.

Q: Will the CD15FC621JO3F fit in the same PCB footprint as the CD15FC621JO3?

A: Yes. Both parts are radial through-hole components with identical lead spacing (0.232" / 5.90 mm) and physical dimensions (0.461" L x 0.209" W / 11.70 mm x 5.30 mm). PCB layout and hole spacing remain unchanged.

Q: Which part should be selected for new designs?

A: Selection should be based on regulatory requirements. For applications requiring RoHS3 compliance or REACH compliance, the CD15FC621JO3F is the appropriate choice. Both parts are active in production and suitable for new designs.
