Key Parameters

Substitute Part Grouping Explanation

Substitution of the CK05BX331K is evaluated based on the following critical parameters provided in the technical specification:

Mounting and Package Compatibility: All substitute parts must be radial, through-hole ceramic capacitors to maintain mechanical and electrical compatibility with existing PCB layouts.

Electrical Specification Alignment: Substitute parts must match the primary capacitance value, voltage rating, and tolerance classification. The capacitance designation "331K" indicates 330 pF with K-class tolerance.

Material and Temperature Performance: Ceramic capacitor dielectric material (temperature coefficient) and operating temperature range determine thermal stability and long-term reliability in the application environment.

Regulatory and Compliance Status: Product status must be active, and compliance certifications (ECCN, HTSUS) must align with end-use requirements and supply chain regulations.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration—Compliance Requirements: The main part (CK05BX331K) carries RoHS non-compliance status, while the substitute C317C331K2R5TA is ROHS3 compliant. Selection between these parts depends on end-use regulatory requirements. Applications subject to RoHS directives or requiring ROHS3 compliance must use the substitute part.

Product Availability and Supply Chain Status: Both parts maintain active product status with confirmed inventory. The main part has 844 pieces in stock; the substitute has 1071 pieces. Active status ensures continued availability for both immediate and future requirements.

Electrical and Mechanical Compatibility: Both parts are radial ceramic capacitors with matching capacitance (330 pF), tolerance (±10%), and through-hole mounting. The substitute provides explicit voltage rating (200V) and temperature coefficient (X7R) specifications, offering enhanced thermal stability across the operating range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: What makes C317C331K2R5TA a suitable substitute for CK05BX331K?

A: Both parts are radial ceramic capacitors with identical 330 pF capacitance and ±10% tolerance. Both are active products with through-hole mounting and matching regulatory codes (ECCN EAR99, HTSUS 8532.24.0060). The substitute offers explicit electrical specifications including 200V voltage rating and X7R temperature coefficient.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS status reflects manufacturing process and material composition compliance with regulatory directives, not electrical performance. The main part is RoHS non-compliant; the substitute is ROHS3 compliant. Selection depends on whether the end application or supply chain requires RoHS certification.

Q: Are the physical dimensions and lead spacing compatible?

A: Both parts use radial, through-hole packaging with 0.200" (5.08mm) lead spacing, ensuring PCB footprint compatibility. The substitute part maximum seated height is 0.200" (5.08mm), confirming dimensional compatibility for standard circuit board designs.

Q: Can these parts be directly swapped in existing designs?

A: Yes. Both parts share identical mounting type (through-hole radial), capacitance value (330 pF), tolerance (±10%), lead spacing (0.200"), and regulatory classification (ECCN EAR99, HTSUS 8532.24.0060). Physical and electrical compatibility allows direct substitution, subject to compliance requirements.

Q: What should I verify before selecting a substitute part?

A: Confirm the application's voltage requirement (the substitute specifies 200V rating), operating temperature range (the substitute covers -55°C ~ 125°C), and RoHS compliance mandates. Verify PCB layout dimensions match the 0.200" lead spacing and 0.200" maximum height specifications.
