Substitute Part Grouping Explanation

Substitution for the GCM1885C1H6R9DA16D is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 6.9 pF (exact match required)
• Voltage Rating: 50V minimum (equal or higher acceptable)
• Temperature Coefficient: C0G/NP0 (mandatory for stability and frequency characteristics)
• Package Format: 0603 (1608 Metric) surface mount (physical and electrical compatibility)
• Operating Temperature Range: -55°C to 125°C (functional envelope)
• Compliance Standards: RoHS3 and REACH compliance (regulatory requirement)

The KEMET CBR06C699B5GAC meets all substitution criteria. While it features a tighter tolerance specification (±0.1 pF versus ±0.5 pF), this represents an improvement in precision and does not compromise compatibility. Both parts share identical package geometry, voltage rating, temperature coefficient, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CBR06C699B5GAC from KEMET is a direct functional equivalent to the GCM1885C1H6R9DA16D. Both components satisfy identical electrical specifications, package requirements, and regulatory compliance standards. The KEMET part offers the additional advantage of Active product status, ensuring continued availability and manufacturing support. The improved tolerance specification (±0.1 pF) of the KEMET component provides enhanced precision without introducing any compatibility concerns. Selection between these parts should be based on supply chain availability, lead time requirements, and cost considerations, as both are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the CBR06C699B5GAC replace the GCM1885C1H6R9DA16D in existing designs?

A: Yes. Both parts share identical capacitance values, voltage ratings, temperature coefficients, package formats, and operating temperature ranges. Physical dimensions and mounting characteristics are equivalent, enabling direct substitution on PCBs designed for the 0603 package.

Q: Does the tighter tolerance of the KEMET part affect compatibility?

A: No. A tolerance of ±0.1 pF is more restrictive than ±0.5 pF, meaning the KEMET part maintains capacitance within a narrower range. This represents improved precision and does not create compatibility issues in circuits designed for the original ±0.5 pF specification.

Q: Are both parts compliant with automotive and industrial standards?

A: The GCM1885C1H6R9DA16D carries AEC-Q200 automotive qualification. The CBR06C699B5GAC does not list AEC-Q200 in the provided specifications. If automotive qualification is a mandatory requirement, this distinction must be evaluated against application needs.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the Murata part has been discontinued or superseded. It may still be available from inventory but will not receive design updates or long-term manufacturing support. The KEMET equivalent, with Active status, provides assurance of continued availability and support.

Q: Are there any differences in moisture sensitivity or storage requirements?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling. Storage and handling procedures are equivalent.

Q: Can these parts be used interchangeably in RF and microwave applications?

A: Yes, from a package and electrical standpoint. The CBR06C699B5GAC is specifically marketed for RF and microwave applications with stated features of High Q, Low Loss, and Ultra Low ESR. The GCM1885C1H6R9DA16D does not list these features in the provided data. If RF performance characteristics are critical, the KEMET part may offer performance advantages.
