CD19FD102GO3F Equivalent & Substitute Parts

Part Overview

The CD19FD102GO3F is a 1000 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 500 V operation in radial through-hole configuration. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and high voltage performance. Mica capacitors are selected for applications demanding low loss, excellent frequency stability, and reliable operation across extended temperature ranges from -55°C to 125°C. Substitute parts are identified when original inventory becomes unavailable or when design requirements permit alternative series within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the CD19FD102GO3F are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

Capacitance value: 1000 pF
Voltage rating: 500 V minimum
Tolerance: ±2% or tighter
Dielectric material: Mica

Mechanical Parameters (Must Match):

Mounting type: Through Hole
Package configuration: Radial
Lead spacing: 0.343" (8.70mm)
Physical dimensions: 0.650" L x 0.220" W (16.50mm x 5.60mm)
Maximum seated height: 0.520" (13.20mm)

Environmental Parameters (Must Match or Exceed):

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

The CM06FD102GO3 meets all electrical and mechanical requirements for direct substitution. Both parts share identical capacitance, voltage rating, tolerance, dielectric material, mounting configuration, lead spacing, and physical dimensions. Both operate across the full -55°C to 125°C temperature range.

Engineering Selection Recommendations

Primary Selection: CD19FD102GO3F

The CD19FD102GO3F is the preferred component for new designs and applications requiring regulatory compliance. This part carries ROHS3 compliance certification and REACH Unaffected status, making it suitable for applications subject to environmental and regulatory restrictions in the European Union and equivalent markets. The part is currently in Active product status with 639 units in stock.

Alternative Selection: CM06FD102GO3

The CM06FD102GO3 provides electrical and mechanical equivalence to the CD19FD102GO3F and is suitable for applications where RoHS and REACH compliance are not required. This part is also in Active product status with 738 units in stock. The CM06 series represents an earlier CDE mica capacitor design that maintains full electrical and mechanical compatibility with the CD19 series.

Compliance Considerations:

Selection between these two parts must account for end-application regulatory requirements. The CD19FD102GO3F is mandatory for applications subject to RoHS3 or REACH regulations. The CM06FD102GO3 is acceptable only in applications where such compliance is not a design requirement or where legacy component specifications are explicitly maintained.

Frequently Asked Questions (FAQ)

Q: Can CM06FD102GO3 be used as a direct replacement for CD19FD102GO3F in all applications?

A: The CM06FD102GO3 provides direct electrical and mechanical substitution. However, regulatory compliance differences must be evaluated. If the application requires RoHS3 or REACH compliance, the CD19FD102GO3F is the only acceptable choice. For applications without such requirements, the CM06FD102GO3 is electrically and mechanically equivalent.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (1000 pF), voltage rating (500 V), tolerance (±2%), and dielectric material (mica) must match exactly. Both substitute parts meet these requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (0.343" / 8.70mm), length (0.650" / 16.50mm), width (0.220" / 5.60mm), and maximum seated height (0.520" / 13.20mm). PCB footprints are interchangeable.

Q: What is the difference in RoHS and REACH status between these parts?

A: The CD19FD102GO3F is ROHS3 Compliant and REACH Unaffected. The CM06FD102GO3 is RoHS non-compliant and REACH Affected. These differences reflect manufacturing process and material sourcing differences between the two series.

Q: Can either part be used in high-temperature applications?

A: Both parts operate across the full -55°C to 125°C temperature range. Neither part has temperature limitations that would restrict substitution based on thermal requirements alone.

Q: Are both parts currently available?

A: Yes. The CD19FD102GO3F has 639 units in stock, and the CM06FD102GO3 has 738 units in stock. Both are classified as Active product status.
