Substitute Part Grouping Explanation

Substitution eligibility for the GRM1555C2A6R9DA01J is determined by the following critical parameters: capacitance value (6.9 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, REACH Unaffected). Two substitute parts meet these core electrical requirements while offering different trade-offs in package size, tolerance, voltage rating, and product status.

The substitutes are grouped based on their deviation from the original specification:

• GRM0335C2A6R9CA01D: Maintains identical electrical characteristics with improved tolerance (±0.25pF vs ±0.5pF) but uses a smaller 0201 package and is currently Active in production.
• CBR04C699B5GAC: Maintains identical package size (0402) and electrical characteristics but operates at a reduced voltage rating (50V vs 100V) and is optimized for RF/microwave applications with enhanced Q factor and lower ESR.

Parameter Comparison

Engineering Selection Recommendations

GRM0335C2A6R9CA01D is the preferred substitute for applications where PCB space constraints permit package downsizing. This part maintains full electrical compatibility with the original specification while offering superior tolerance performance (±0.25pF) and Active product status, ensuring long-term availability and supply chain stability. The 0201 package requires updated PCB layout and assembly process validation.

CBR04C699B5GAC is suitable for applications where the 50V voltage rating is sufficient and RF/microwave performance characteristics are beneficial. This part maintains the original 0402 package footprint, eliminating PCB redesign requirements. The reduced voltage rating must be evaluated against circuit operating conditions. KEMET's CBR-SMD RF C0G series provides enhanced Q factor and ultra-low ESR characteristics suitable for high-frequency applications.

Both substitutes carry Active product status and full compliance certifications (ROHS3, REACH Unaffected), ensuring regulatory compliance and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can GRM0335C2A6R9CA01D be used as a direct replacement without PCB modification?

A: No. The GRM0335C2A6R9CA01D uses a 0201 package (0.60mm × 0.30mm) compared to the original 0402 package (1.00mm × 0.50mm). PCB footprint redesign and assembly process updates are required.

Q: What is the voltage derating consideration for CBR04C699B5GAC?

A: The CBR04C699B5GAC operates at 50V rated voltage versus the original 100V rating. This part is suitable only for circuits where the maximum operating voltage does not exceed 50V. Verify circuit peak voltage conditions before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both GRM0335C2A6R9CA01D and CBR04C699B5GAC are ROHS3 Compliant with REACH Unaffected status, matching the original part's compliance profile.

Q: Which substitute offers the best tolerance performance?

A: CBR04C699B5GAC provides the tightest tolerance at ±0.1pF, followed by GRM0335C2A6R9CA01D at ±0.25pF, compared to the original ±0.5pF specification.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All three parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the primary application difference between the substitutes?

A: GRM0335C2A6R9CA01D is optimized for general-purpose applications with improved tolerance. CBR04C699B5GAC is specifically designed for RF, microwave, and high-frequency applications with enhanced Q factor and ultra-low ESR characteristics.
