Substitute Part Grouping Explanation

Substitution of the CD15FD181FO3 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 180 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Type: Mica (exact match required)
• Mounting Configuration: Through Hole Radial (exact match required)
• Physical Dimensions: Lead spacing 0.232" (5.90 mm), body dimensions 0.461" L x 0.189" W (11.70 mm x 4.80 mm), height 0.370" (9.40 mm) (exact match required)
• Temperature Range: -55°C to 125°C (exact match required)

The substitute part CD15FD181FO3F meets all electrical and mechanical parameters identically to the main part. Differences exist only in compliance certifications and regulatory status.

Parameter Comparison

Engineering Selection Recommendations

CD15FD181FO3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. This part maintains active production status with established supply availability.

CD15FD181FO3F is the appropriate selection for designs requiring ROHS3 compliance and REACH-unaffected component sourcing. This variant provides identical electrical and mechanical performance while meeting stricter regulatory requirements. Higher inventory availability (2733 units) supports extended production runs and supply chain resilience.

Both parts are functionally interchangeable at the circuit level. Selection between them depends solely on compliance requirements mandated by the end application, customer specifications, or regional regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Are CD15FD181FO3 and CD15FD181FO3F electrically identical?

A: Yes. Both parts deliver identical capacitance (180 pF), tolerance (±1%), voltage rating (500 V), temperature range (-55°C to 125°C), and all other electrical parameters. They are functionally equivalent in circuit operation.

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

A: Yes. Both parts share identical physical dimensions, lead spacing (0.232" / 5.90 mm), body size (0.461" L x 0.189" W / 11.70 mm x 4.80 mm), and mounting height (0.370" / 9.40 mm). They are mechanically interchangeable in through-hole radial mounting applications.

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

A: The primary differences are compliance certifications. CD15FD181FO3F is ROHS3 compliant and REACH unaffected, while CD15FD181FO3 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which part should I specify for new designs?

A: Specify CD15FD181FO3F for new designs requiring ROHS3 compliance or REACH-unaffected sourcing. Both parts remain in active production; selection depends on regulatory requirements applicable to your application.

Q: Is there a performance difference between these parts?

A: No. Both parts operate identically across all electrical parameters, temperature ranges, and mechanical specifications. Performance differences do not exist.

Q: What is the lead spacing for these capacitors?

A: Lead spacing is 0.232 inches (5.90 millimeters) for both parts, measured center-to-center between radial leads.
