CD15FD391GO3F Equivalent & Substitute Parts

Part Overview

The CD15FD391GO3F is a 390 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 ROHS3 compliant. Mica capacitors of this specification are used in general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. Substitute parts are identified when equivalent electrical parameters and mechanical compatibility are maintained across the CD15 and CM05 series.

Substitute Part Grouping Explanation

Substitution eligibility for the CD15FD391GO3F is determined by strict equivalence in the following parameters:

Critical Electrical Parameters:

Capacitance value: 390 pF
Tolerance: ±2%
Voltage rating: 500 V
Dielectric material: Mica

Critical Mechanical Parameters:

Mounting type: Through Hole
Package configuration: Radial
Lead spacing: 0.232" (5.90mm)
Physical dimensions: 0.469" L x 0.209" W (11.90mm x 5.30mm)
Maximum seated height: 0.390" (9.90mm)

Operating Conditions:

Temperature range: -55°C to 125°C

Two substitute parts meet these criteria: CD15FD391GO3 (same series, different packaging designation) and CM05FD391GO3 (alternate series with identical electrical and mechanical specifications).

Engineering Selection Recommendations

CD15FD391GO3F (Primary Part): This part is the preferred selection for applications requiring ROHS3 compliance and REACH unaffected status. Active product status confirms ongoing manufacturer support and availability.

CD15FD391GO3 (Substitute - Same Series): This substitute provides identical electrical and mechanical performance within the CD15 series. Selection of this part requires acceptance of RoHS non-compliant and REACH affected status. Use this substitute only when regulatory requirements permit non-compliant components or when primary part availability is insufficient.

CM05FD391GO3 (Substitute - Alternate Series): This substitute provides identical electrical and mechanical performance within the CM05 series. Selection of this part requires acceptance of RoHS non-compliant and REACH affected status. The MSL rating differs (1 - Unlimited versus Not Applicable), indicating different moisture sensitivity classifications. Use this substitute only when regulatory requirements permit non-compliant components or when primary part availability is insufficient.

Frequently Asked Questions (FAQ)

Q: Can CD15FD391GO3 be used as a direct replacement for CD15FD391GO3F?

A: CD15FD391GO3 is electrically and mechanically equivalent. The primary difference is regulatory compliance status: CD15FD391GO3F is ROHS3 compliant and REACH unaffected, while CD15FD391GO3 is RoHS non-compliant and REACH affected. Direct substitution is possible only if your application permits non-compliant components.

Q: What is the difference between CD15FD391GO3 and CM05FD391GO3?

A: Both parts are electrically and mechanically identical with 390 pF capacitance, 500 V rating, and radial through-hole configuration. The difference is series designation (CD15 versus CM05) and moisture sensitivity level classification. Both are RoHS non-compliant and REACH affected.

Q: Are all three parts pin-compatible?

A: Yes. All three parts share identical lead spacing (0.232" / 5.90mm), physical dimensions (0.469" L x 0.209" W), and maximum seated height (0.390" / 9.90mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Which substitute should I select if RoHS compliance is not required?

A: Both CD15FD391GO3 and CM05FD391GO3 are functionally equivalent substitutes. Selection between them depends on series preference and inventory availability. CD15FD391GO3 maintains the same series as the primary part.

Q: Can these parts be used in high-temperature applications?

A: Yes. All three parts operate across the temperature range -55°C to 125°C, supporting high-temperature circuit requirements within this specification.

Q: What is the significance of the ±2% tolerance specification?

A: The ±2% tolerance indicates that actual capacitance values will fall within 382.2 pF to 397.8 pF. This tight tolerance is maintained across all three parts and is suitable for applications requiring precise capacitance values.
