Substitute Part Grouping Explanation

Substitute parts for the WCAP-CSRF 885392005106 are qualified based on the following critical parameters:

Capacitance value must be 10 pF with tolerance of ±0.1pF. Voltage rating must be 50V or higher. Temperature coefficient must be C0G or NP0 to ensure frequency stability across the operating temperature range of -55°C to 125°C. Package must be 0402 (1005 Metric) surface mount to ensure mechanical and electrical compatibility with existing PCB layouts. Physical dimensions (0.039" L x 0.020" W, 0.022" max thickness) must match for assembly compatibility. RoHS3 compliance and MSL 1 rating are required for regulatory and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

The KYOCERA AVX 04025U100BAT2A qualifies as a parametric equivalent to the Würth Elektronik WCAP-CSRF 885392005106. Both components meet identical electrical specifications (10 pF ±0.1pF at 50V with C0G/NP0 temperature coefficient), mechanical dimensions (0402 package), and regulatory requirements (RoHS3 compliance, MSL 1). Selection between these parts may be based on availability, lead time, or supply chain requirements, as all critical parameters for RF and high-frequency applications are equivalent. Both parts maintain Active product status and are suitable for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the KYOCERA AVX 04025U100BAT2A replace the Würth Elektronik WCAP-CSRF 885392005106 in RF applications?

A: Yes. Both components have identical capacitance (10 pF ±0.1pF), voltage rating (50V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). The 0402 package dimensions and electrical characteristics are equivalent for RF and high-frequency circuit applications.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 0402 (1005 Metric) surface mount package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and 0.022" maximum thickness. PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the WCAP-CSRF 885392005106 and 04025U100BAT2A are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating. REACH status is unaffected for both components.

Q: What is the significance of the C0G/NP0 temperature coefficient for these capacitors?

A: C0G/NP0 temperature coefficient ensures minimal capacitance variation across the operating temperature range of -55°C to 125°C. This stability is critical for RF and high-frequency applications where frequency drift must be controlled.

Q: Can these 10 pF capacitors be used interchangeably in all circuit positions?

A: Yes, provided the circuit design specifies 10 pF ±0.1pF capacitance, 50V minimum voltage rating, C0G/NP0 temperature coefficient, and 0402 surface mount package. Both parts meet these requirements identically.
