Substitute Part Grouping Explanation

Substitution of the CD15FC681FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

  • Capacitance value: 680 pF
  • Tolerance: ±1%
  • Rated voltage: 300 V
  • Dielectric material: Mica
  • Operating temperature range: -55°C to 125°C
  • Mounting type: Through Hole
  • Package configuration: Radial
  • Lead spacing: 0.232" (5.90 mm)
  • Physical dimensions: 0.469" L x 0.209" W (11.90 mm x 5.30 mm)
  • Maximum seated height: 0.390" (9.90 mm)

The CD15FC681FO3F is classified as a parametric equivalent and direct substitute. This part maintains identical electrical specifications and mechanical form factor while offering improved compliance status.

Engineering Selection Recommendations

The CD15FC681FO3F serves as a direct electrical and mechanical substitute for the CD15FC681FO3. Both parts are active products from Cornell Dubilier Electronics in the CD15 series and maintain identical performance characteristics across all critical parameters.

The primary distinction between these parts lies in regulatory compliance status. The CD15FC681FO3F achieves ROHS3 compliance, whereas the CD15FC681FO3 is RoHS non-compliant. Additionally, the CD15FC681FO3F is REACH Unaffected, while the CD15FC681FO3 is REACH Affected. These compliance differences are significant for applications subject to European Union regulations or customer-mandated environmental standards.

From an inventory perspective, the CD15FC681FO3F offers higher stock availability at 1110 pieces compared to 679 pieces for the CD15FC681FO3.

Selection between these parts should be based on regulatory requirements applicable to the end application and supply chain constraints. Both parts are functionally interchangeable in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the CD15FC681FO3F be used as a direct replacement for the CD15FC681FO3 in existing designs?

A: Yes. The CD15FC681FO3F is electrically and mechanically identical to the CD15FC681FO3. Both parts have the same capacitance (680 pF), tolerance (±1%), rated voltage (300 V), operating temperature range (-55°C to 125°C), and physical dimensions. No circuit redesign or PCB layout modification is required.

Q: What is the difference in compliance between these two parts?

A: The CD15FC681FO3F is ROHS3 compliant and REACH Unaffected. The CD15FC681FO3 is RoHS non-compliant and REACH Affected. If your application or customer requirements mandate RoHS or REACH compliance, the CD15FC681FO3F is the appropriate selection.

Q: Are the lead spacings identical between these parts?

A: Yes. Both the CD15FC681FO3 and CD15FC681FO3F have a lead spacing of 0.232" (5.90 mm) and identical radial package dimensions of 0.469" L x 0.209" W (11.90 mm x 5.30 mm). They are pin-compatible and require no PCB modification.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 or REACH compliance, specify the CD15FC681FO3F. For applications without these requirements, either part is acceptable. The CD15FC681FO3F offers higher inventory availability.

Q: Are there any performance differences between these capacitors?

A: No. Both parts are mica dielectric capacitors with identical electrical performance specifications. They operate across the same temperature range, maintain the same tolerance, and are rated for the same voltage.
