CD17FD331JO3 Equivalent & Substitute Parts

Part Overview

The CD17FD331JO3 is a 330 pF mica capacitor rated for 500 V operation in radial through-hole configuration, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for RF applications requiring high Q factor and low loss characteristics. The mica dielectric provides stable performance across the operating temperature range of -55°C to 150°C.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design requirements permit selection from available alternatives that maintain identical electrical and mechanical specifications.

Engineering Selection Recommendations

CD17FD331JO3F as Primary Substitute:

The CD17FD331JO3F is a direct parametric equivalent to the CD17FD331JO3. Both parts are manufactured by Cornell Dubilier Electronics within the CD17 series and maintain identical electrical and mechanical specifications.

A key distinction exists in regulatory compliance status:

• CD17FD331JO3: RoHS non-compliant; REACH Affected
• CD17FD331JO3F: ROHS3 Compliant; REACH Unaffected

Selection between these parts is determined by application requirements and regulatory constraints. When RoHS3 compliance is mandated by design specifications or end-use regulations, the CD17FD331JO3F is the appropriate selection. When RoHS compliance is not a requirement, either part satisfies the electrical and mechanical design criteria.

Both parts are Active status products with confirmed inventory availability. The CD17FD331JO3F currently maintains higher inventory levels (1013 pcs vs. 745 pcs), which may influence procurement decisions in supply-constrained scenarios.

Frequently Asked Questions (FAQ)

Q: Can CD17FD331JO3F be used as a direct replacement for CD17FD331JO3 in all applications?

A: Yes, from an electrical and mechanical standpoint. The CD17FD331JO3F maintains identical capacitance (330 pF), tolerance (±5%), voltage rating (500 V), dielectric material (Mica), operating temperature range (-55°C to 150°C), and physical dimensions. The radial through-hole package, lead spacing (0.232"), and performance characteristics (RF, High Q, Low Loss) are identical. Selection should account for regulatory compliance requirements, as the CD17FD331JO3F is ROHS3 compliant while the CD17FD331JO3 is not.

Q: What are the critical parameters that define substitution eligibility for the CD17FD331JO3?

A: Substitution eligibility is determined by exact equivalence in: capacitance value (330 pF), tolerance (±5%), rated voltage (500 V), dielectric material (Mica), mounting type (Through Hole), package configuration (Radial), lead spacing (0.232" / 5.90mm), physical dimensions (0.469" L x 0.209" W), maximum seated height (0.390"), and operating temperature range (-55°C to 150°C). Any deviation in these parameters disqualifies a part from substitution.

Q: Are there any physical compatibility concerns when substituting CD17FD331JO3 with CD17FD331JO3F?

A: No. Both parts share identical physical dimensions, lead spacing, and radial through-hole package configuration. PCB layout, mounting hole spacing, and component clearance requirements remain unchanged. The parts are mechanically interchangeable.

Q: What is the difference between CD17FD331JO3 and CD17FD331JO3F regarding compliance?

A: The CD17FD331JO3F is ROHS3 compliant and REACH unaffected, while the CD17FD331JO3 is RoHS non-compliant and REACH affected. Both parts carry identical ECCN (EAR99) and HTSUS (8532.29.0020) classifications. Compliance selection depends on end-use application and regional regulatory requirements.

Q: Can these parts be used in RF applications?

A: Yes. Both the CD17FD331JO3 and CD17FD331JO3F are specified with RF, High Q, and Low Loss features, indicating suitability for radio frequency applications requiring stable performance and minimal signal loss.
