Key Parameters

Substitute Part Grouping Explanation

Substitution of the YFF32SC1E101M is determined by the following critical parameters:

• Capacitance Value: Must be 100 pF (exact match required)
• Package Configuration: Must be 1206 (3216 Metric), 4 PC Pad surface mount
• DC Resistance: Must not exceed 600mOhm
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: Must meet or exceed the application voltage requirement
• Compliance Standards: RoHS3 compliance required for regulatory alignment

The W3F11A1018AT1A from KYOCERA AVX meets these substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The W3F11A1018AT1A is a direct functional substitute for the YFF32SC1E101M. The substitute part maintains identical capacitance, package configuration, DC resistance specification, and operating temperature range. The substitute provides enhanced voltage rating (100V versus 25V) and increased current capacity (300 mA versus 200 mA), offering superior performance margins for the same physical footprint.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility. The substitute part's active product status ensures long-term availability and supply chain continuity, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: Can the W3F11A1018AT1A be used as a direct replacement for the YFF32SC1E101M?

A: Yes. Both parts share identical capacitance (100 pF), package configuration (1206 with 4 PC Pad), DC resistance (600mOhm maximum), and operating temperature range (-55°C to 125°C). The substitute meets all electrical and mechanical requirements for direct substitution.

Q: What are the advantages of using the W3F11A1018AT1A?

A: The substitute provides a higher voltage rating (100V versus 25V) and increased current capacity (300 mA versus 200 mA) within the same package footprint. Additionally, the part maintains active product status, ensuring reliable long-term procurement availability.

Q: Are there any physical dimension differences between these parts?

A: Minor dimensional variations exist. The YFF32SC1E101M has a maximum height of 0.039" (1.00mm) and width of 0.049" (1.25mm), while the W3F11A1018AT1A has a maximum height of 0.050" (1.27mm) and width of 0.063" (1.60mm). Both maintain the same 0.126" length (3.20mm). These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the YFF32SC1E101M and W3F11A1018AT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Both share the same ECCN (EAR99) and HTSUS classification (8532.24.0020).

Q: What is the packaging format for the substitute part?

A: The W3F11A1018AT1A is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
