Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAS18C102KARFC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1000 pF
• Tolerance: ±10%
• Voltage rating: 250VAC
• Temperature coefficient: X7R
• Safety ratings: X1, Y2

Mechanical Parameters:

• Package type: 1812 (4532 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.177" L × 0.126" W (4.50mm × 3.20mm)
• Maximum thickness: 0.110" (2.80mm)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: MSL 1
• RoHS3 compliance
• ECCN: EAR99
• HTSUS code: 8532.24.0020

Substitute parts must match all parameters listed above. Deviations in any electrical, mechanical, or compliance specification disqualify a part from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CAS18C102KARFC and KGK43JR73H102KV2B are active production parts with full ROHS3 compliance and identical electrical, mechanical, and environmental specifications. Selection between these parts is based on the following factors:

Inventory Availability: The KGK43JR73H102KV2B (KYOCERA AVX) has 2070 units in stock, compared to 1147 units for the CAS18C102KARFC (KEMET). Higher inventory availability may support extended production runs or reduce lead time risk.

Manufacturer Qualification: Both manufacturers are established suppliers of safety-rated ceramic capacitors. Component selection should align with existing manufacturer qualification requirements and supply chain agreements within your organization.

Compliance Certification: Both parts carry identical compliance certifications: ROHS3, EAR99 export classification, and MSL 1 moisture sensitivity rating. No compliance advantage exists between the two options.

Tape & Reel Packaging: Both parts are supplied in Tape & Reel format, ensuring compatibility with automated assembly equipment and standard component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the KGK43JR73H102KV2B replace the CAS18C102KARFC in existing designs?

A: Yes. The KGK43JR73H102KV2B is a parametric equivalent with identical electrical ratings (1000 pF, 250VAC, X7R), safety classifications (X1/Y2), mechanical dimensions (1812 package), and compliance certifications. Direct substitution is supported without design modification.
