Substitute Part Grouping Explanation

Substitution of the CD15FD151FO3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD15FD151FO3F maintains identical specifications in the following categories:

Electrical Parameters: Capacitance value (150 pF), tolerance (±1%), voltage rating (500 V), and dielectric material (mica) are identical between the main part and substitute.

Mechanical Parameters: Mounting type (through hole), package configuration (radial), lead spacing (0.232" / 5.90 mm), physical dimensions (0.461" L × 0.189" W), and maximum seated height (0.370") are identical.

Thermal Parameters: Operating temperature range (-55°C to 125°C) is identical.

Series Classification: Both parts belong to the CD15 series and maintain active product status.

The only distinction between these parts exists in regulatory compliance status, which does not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

CD15FD151FO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. This part is recommended for legacy equipment, military applications, or systems where existing component qualification takes precedence.

CD15FD151FO3F is the appropriate selection for new designs, commercial products, and applications subject to RoHS3 compliance requirements or REACH regulations. This variant eliminates regulatory compliance concerns while maintaining complete electrical and mechanical equivalence.

Both parts are classified as active products with adequate inventory levels. Selection between these substitutes depends solely on the regulatory and compliance requirements of the end application, not on electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Are CD15FD151FO3 and CD15FD151FO3F electrically interchangeable?

A: Yes. Both parts have identical capacitance (150 pF), tolerance (±1%), voltage rating (500 V), and dielectric material (mica). Electrical performance is equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts share identical mechanical specifications: radial through-hole mounting, 0.232" lead spacing, 0.461" L × 0.189" W dimensions, and 0.370" maximum seated height. PCB layout and footprint compatibility are identical.

Q: What is the difference between these two part numbers?

A: The primary difference is regulatory compliance status. CD15FD151FO3F is ROHS3 compliant and REACH unaffected, while CD15FD151FO3 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.
