Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD19FA103FO3 is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical capacitance (10000 pF), tolerance (±1%), rated voltage (100 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70 mm), and physical dimensions (0.720" L x 0.370" W / 18.30 mm x 9.40 mm, height 0.598" / 15.20 mm maximum). These parameters ensure direct functional and mechanical compatibility within circuit designs and printed circuit board layouts. Compliance certifications and regulatory status may differ between equivalent parts without affecting electrical or mechanical substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The CD19FA103FO3 and CD19FA103FO3F are electrically and mechanically equivalent 10000 pF mica capacitors from Cornell Dubilier Electronics. Both parts are active products with identical electrical specifications and physical dimensions, ensuring direct substitution in circuit applications.

The primary distinction between these parts is regulatory compliance status. The CD19FA103FO3F carries ROHS3 compliance certification and REACH Unaffected status, whereas the CD19FA103FO3 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on the specific regulatory requirements of the end application and target market. Applications subject to RoHS3 or REACH restrictions require the CD19FA103FO3F variant. Applications without such regulatory constraints may utilize either part based on availability and supply chain considerations. Both parts maintain identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD19FA103FO3F be used as a direct replacement for CD19FA103FO3?

A: Yes. The CD19FA103FO3F is a direct electrical and mechanical equivalent. Both parts share identical capacitance (10000 pF), tolerance (±1%), voltage rating (100 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (0.343" / 8.70 mm), and physical dimensions. Direct substitution is supported in circuit designs and PCB layouts.

Q: What is the difference between CD19FA103FO3 and CD19FA103FO3F?

A: The electrical and mechanical specifications are identical. The CD19FA103FO3F differs in regulatory compliance: it carries ROHS3 certification and REACH Unaffected status, while the CD19FA103FO3 is RoHS non-compliant and REACH Affected. Selection depends on regulatory requirements for the specific application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions: 0.720" L x 0.370" W (18.30 mm x 9.40 mm) with a maximum seated height of 0.598" (15.20 mm). Lead spacing is 0.343" (8.70 mm) for both variants. PCB layout and mechanical clearance requirements are identical.

Q: Which part should be selected for RoHS3-compliant applications?

A: The CD19FA103FO3F is ROHS3 compliant and must be used for applications subject to RoHS3 regulatory requirements. The CD19FA103FO3 is RoHS non-compliant and is not suitable for such applications.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical and mechanical interchangeability is confirmed. Regulatory compliance requirements must be evaluated for the specific application. If the design is subject to RoHS3 or REACH restrictions, the CD19FA103FO3F is required. Otherwise, either part may be used based on availability.
