CDR31BP330BFWS Equivalent & Substitute Parts

Part Overview

The CDR31BP330BFWS is a ceramic capacitor manufactured by KYOCERA AVX, classified as a high-reliability surface mount multilayer ceramic capacitor (MLCC). This component is currently in active production status with 1163 pieces available in bulk packaging. The part is RoHS non-compliant and carries an unlimited moisture sensitivity level (MSL 1), making it suitable for applications requiring stable performance across extended temperature ranges. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when specific packaging requirements necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR31BP330BFWS is determined by the following criteria:

Manufacturer Alignment: Both the main part and substitute must originate from KYOCERA AVX to ensure consistent design specifications and quality standards.

Regulatory Compliance: Substitute parts must maintain compatibility with the same export control classifications (ECCN: EAR99) and tariff codes (HTSUS: 8532.24.0020).

Moisture Sensitivity: The MSL 1 rating (unlimited moisture sensitivity) of the main part establishes the baseline for substitute compatibility, ensuring no additional moisture handling requirements are imposed.

Component Category: All substitutes must function as ceramic capacitors within the multilayer ceramic capacitor (MLCC) classification.

The identified substitute part KGM21BCG2A330KT meets these criteria while offering alternative packaging (Cut Tape and Digi-Reel) and documented electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The CDR31BP330BFWS remains the specified component when bulk packaging is required and RoHS non-compliance is acceptable for the application. Current inventory of 1163 pieces supports immediate procurement.

Substitute Selection Criteria: The KGM21BCG2A330KT serves as an alternative when the following conditions apply:

1. Cut Tape or Digi-Reel packaging formats are required for automated assembly processes
2. ROHS3 compliance is mandated by customer specifications or regulatory requirements
3. Higher inventory availability (7804 pieces) is needed for large-volume production runs
4. Documented electrical specifications (100V rating, C0G/NP0 temperature coefficient, ±10% tolerance) align with circuit design requirements

Compliance Consideration: The substitute part KGM21BCG2A330KT carries ROHS3 compliance status, whereas the main part is RoHS non-compliant. This distinction must be evaluated against end-product regulatory requirements before substitution.

Packaging Impact: Both parts utilize identical 0805 (2012 Metric) surface mount packages with matching footprints. The packaging format difference (Bulk versus Cut Tape/Digi-Reel) affects only procurement and assembly logistics, not electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG2A330KT be used as a direct replacement for CDR31BP330BFWS in all applications?

A: Both parts share identical 33 pF capacitance values, 0805 package dimensions, and MSL 1 moisture sensitivity ratings. The substitute is electrically compatible when the application tolerates ROHS3 compliance and the documented 100V voltage rating and C0G/NP0 temperature coefficient specifications. Verify that your circuit design requirements align with the substitute's published electrical parameters.

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

A: The main differences are packaging format (Bulk versus Cut Tape/Digi-Reel), RoHS compliance status (non-compliant versus ROHS3 compliant), and inventory availability. Both are manufactured by KYOCERA AVX and share the same 0805 surface mount package footprint.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both parts function identically in circuit applications. The compliance difference is a regulatory and procurement consideration, not a performance factor.

Q: Are there any thermal or frequency limitations I should consider?

A: The substitute part KGM21BCG2A330KT specifies an operating temperature range of -55°C to 125°C. Verify this range meets your application requirements. No frequency limitations are provided in the available specifications for either part.

Q: Can I mix these parts in the same production batch?

A: Both parts are surface mount components with identical 0805 package dimensions and footprints. From a physical assembly perspective, they are interchangeable. However, verify that your quality assurance and traceability procedures permit mixing parts with different RoHS compliance statuses and packaging formats within a single production lot.

Q: What should I do if both parts become unavailable?

A: Contact KYOCERA AVX directly for alternative part numbers within the KGM series (C0G ceramic capacitors) or CDR series that maintain the 33 pF capacitance value and 0805 package specification. Ensure any alternative maintains compatibility with your circuit's voltage and temperature coefficient requirements.
