Substitute Part Grouping Explanation

Substitute parts for the CM06FD821JO3 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Primary Equivalence Parameters:

Capacitance value: 820 pF (exact match required)
Voltage rating: 500 V (exact match required)
Tolerance: ±5% (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 type: Radial (exact match required)
Lead spacing: 0.343" / 8.70 mm (exact match required)
Physical dimensions: 0.650" L x 0.209" W / 16.50 mm x 5.30 mm (exact match required)

The identified substitutes CD19FD821JO3 and CD19FD821JO3F meet all primary equivalence parameters. Differences exist only in regulatory compliance status and series designation (CD19 versus CM06), which do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

CM06FD821JO3 (Primary Part): Use this part number when the original specification explicitly requires the CM06 series designation. This part is RoHS non-compliant and REACH Affected. Current inventory of 956 units supports immediate availability.

CD19FD821JO3 (Substitute - RoHS Non-Compliant): This substitute maintains identical electrical and mechanical specifications to the CM06FD821JO3. Both parts share RoHS non-compliant and REACH Affected status. The CD19FD821JO3 offers higher inventory availability (2105 units) and is suitable for applications where RoHS compliance is not required. Use this part when supply of the CM06 series is constrained.

CD19FD821JO3F (Substitute - RoHS3 Compliant): This part number is the RoHS3-compliant variant of the CD19 series. It maintains all electrical and mechanical equivalence to the CM06FD821JO3 while offering REACH Unaffected status. Select this part for applications subject to RoHS3 or REACH compliance requirements. Inventory of 1014 units ensures availability for compliant applications.

All three parts are manufactured by Cornell Dubilier Electronics and maintain Active product status, ensuring long-term supply viability.

Frequently Asked Questions (FAQ)

Q: Can CD19FD821JO3 be used as a direct replacement for CM06FD821JO3?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (820 pF), voltage rating (500 V), tolerance (±5%), dielectric material (Mica), operating temperature range (-55°C to 125°C), mounting type (Through Hole), package type (Radial), lead spacing (0.343" / 8.70 mm), and physical dimensions (0.650" L x 0.209" W / 16.50 mm x 5.30 mm). The primary difference is regulatory compliance status.

Q: What is the difference between CD19FD821JO3 and CD19FD821JO3F?

A: Both parts are electrically and mechanically identical. The CD19FD821JO3F is RoHS3 Compliant and REACH Unaffected, while the CD19FD821JO3 is RoHS non-compliant and REACH Affected. Select CD19FD821JO3F for applications requiring RoHS3 or REACH compliance.

Q: Are these parts pin-compatible?

A: Yes. All three parts feature identical lead spacing (0.343" / 8.70 mm) and radial through-hole package configuration, ensuring direct PCB compatibility without layout modifications.

Q: What is the physical footprint difference between these parts?

A: There is no physical footprint difference. All three parts share identical dimensions: 0.650" L x 0.209" W (16.50 mm x 5.30 mm) with maximum seated height of 0.512" (13.00 mm).

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 or REACH compliance requirements, specify CD19FD821JO3F. For applications without regulatory compliance constraints, either CM06FD821JO3 or CD19FD821JO3 may be used based on availability and supply chain preferences.
