CD19FC682FO3 Mica Capacitor Equivalent & Substitute Parts

Part Overview

The CD19FC682FO3 is a 6800 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD19 series. This through-hole radial capacitor operates at 300 V rated voltage with ±1% tolerance and is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

The CD19FC682FO3 is classified as Active product status. Identifying equivalent and substitute parts is necessary for procurement flexibility, inventory management, and ensuring design continuity when the primary part becomes unavailable or when compliance requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FC682FO3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 6800 pF
• Tolerance: ±1%
• Rated voltage: 300 V
• Dielectric material: Mica

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.343" (8.70 mm)
• Physical dimensions: 0.689" L x 0.331" W (17.50 mm x 8.40 mm)
• Maximum seated height: 0.571" (14.50 mm)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The CD19FC682FO3F is identified as a parametric equivalent substitute based on complete alignment with all specified electrical, mechanical, and environmental parameters.

Engineering Selection Recommendations

CD19FC682FO3F as Primary Substitute:

The CD19FC682FO3F is a direct parametric equivalent to the CD19FC682FO3 across all electrical, mechanical, and environmental specifications. Both parts are Active status products from Cornell Dubilier Electronics in the CD19 series.

The CD19FC682FO3F offers improved compliance status compared to the original part. It is ROHS3 compliant and REACH unaffected, whereas the CD19FC682FO3 is RoHS non-compliant and REACH affected. For applications subject to regulatory compliance requirements or procurement policies mandating RoHS compliance, the CD19FC682FO3F is the appropriate selection.

For applications without compliance constraints, both parts are functionally and mechanically interchangeable. Selection between them should be based on organizational compliance requirements and regulatory obligations applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can CD19FC682FO3F be used as a direct replacement for CD19FC682FO3?

A: Yes. The CD19FC682FO3F is a parametric equivalent with identical electrical specifications (6800 pF, ±1%, 300 V), dielectric material (Mica), operating temperature range (-55°C to 125°C), and mechanical configuration (Through Hole, Radial, 0.343" lead spacing, identical dimensions). Both parts are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between CD19FC682FO3 and CD19FC682FO3F?

A: The primary differences are compliance certifications. The CD19FC682FO3F is ROHS3 compliant and REACH unaffected, while the CD19FC682FO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts share identical mechanical specifications: Radial through-hole package, 0.689" L x 0.331" W (17.50 mm x 8.40 mm) dimensions, 0.343" (8.70 mm) lead spacing, and 0.571" (14.50 mm) maximum seated height. PCB layout and mounting procedures are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For designs subject to RoHS or REACH compliance mandates, the CD19FC682FO3F is the appropriate choice. For applications without such constraints, either part is acceptable based on availability and procurement policy.

Q: Are both parts currently available?

A: Yes. The CD19FC682FO3 has 786 pieces in stock, and the CD19FC682FO3F has 998 pieces in stock as new original inventory.
