CD30FD912GO3F Equivalent & Substitute Parts

Part Overview

The CD30FD912GO3F is a 9100 pF mica capacitor manufactured by Cornell Dubilier Electronics (CDE) in the CD30 series. This through-hole radial capacitor operates at 500 V with ±2% tolerance and is rated for temperatures from -55°C to 125°C. The part is currently active in production with 940 units in stock. Mica capacitors of this specification are used in general-purpose applications requiring stable capacitance, low loss, and high voltage performance. Alternative models may be required due to inventory constraints, compliance requirements, or specific application needs.

Substitute Part Grouping Explanation

Substitution of the CD30FD912GO3F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 9100 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Voltage Rating: 500 V (exact match required)
• Dielectric Material: Mica (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.437" / 11.10mm (exact match required)
• Physical Dimensions: 0.791" L x 0.331" W / 20.10mm x 8.40mm (exact match required)

The CD30FD912GO3 qualifies as a parametric equivalent based on identical electrical and mechanical specifications. Differences in compliance status and inventory availability are noted in the parameter comparison table.

Engineering Selection Recommendations

Primary Selection: CD30FD912GO3F is the recommended choice for applications requiring ROHS3 compliance and REACH unaffected status. This part maintains active production status with higher inventory availability (940 units).

Alternative Selection: CD30FD912GO3 provides electrical and mechanical equivalence but carries RoHS non-compliance and REACH affected designation. This substitute is suitable only for applications where regulatory compliance is not a requirement or where legacy system maintenance permits non-compliant components.

Both parts are manufactured by Cornell Dubilier Electronics in the CD30 series and share identical electrical performance characteristics, physical dimensions, and thermal operating range. Selection between these parts depends solely on compliance requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can CD30FD912GO3 be used as a direct replacement for CD30FD912GO3F?

A: CD30FD912GO3 is electrically and mechanically equivalent to CD30FD912GO3F. Both parts have identical capacitance (9100 pF), tolerance (±2%), voltage rating (500 V), physical dimensions, and lead spacing. However, CD30FD912GO3 is RoHS non-compliant and REACH affected, while CD30FD912GO3F is ROHS3 compliant and REACH unaffected. Substitution is permissible only in applications where these compliance differences are acceptable.

Q: What are the critical parameters that must match for substitution?

A: Substitution requires exact equivalence in capacitance value (9100 pF), tolerance (±2%), voltage rating (500 V), dielectric material (mica), mounting type (through hole), package configuration (radial), lead spacing (0.437" / 11.10mm), and physical dimensions (0.791" L x 0.331" W / 20.10mm x 8.40mm).

Q: Are there any physical compatibility issues between these parts?

A: No. Both CD30FD912GO3F and CD30FD912GO3 have identical physical dimensions, lead spacing, and mounting configuration. They are mechanically interchangeable in PCB layouts designed for radial through-hole capacitors with 11.10mm lead spacing.

Q: What is the difference in compliance status between these parts?

A: CD30FD912GO3F is ROHS3 compliant and REACH unaffected. CD30FD912GO3 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must use CD30FD912GO3F.

Q: Do these parts have different thermal performance?

A: No. Both parts operate across the same temperature range (-55°C to 125°C) and use identical mica dielectric material, ensuring equivalent thermal stability and performance characteristics.
