Substitute Part Grouping Explanation

Substitute parts for the 0805J2000221FCT are qualified based on matching the following critical electrical and mechanical parameters:

• Capacitance value: 220 pF
• Tolerance: ±1%
• Voltage rating: 200V
• Temperature coefficient: C0G, NP0
• Operating temperature range: -55°C to 125°C
• Package: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCC
• Packaging format: Tape & Reel (TR)
• Compliance: ROHS3 Compliant, REACH Unaffected

The identified substitutes maintain electrical equivalence and mechanical compatibility with the original part. Physical dimensions remain within acceptable tolerances for PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet identical electrical specifications and regulatory requirements. Selection between the main part and substitutes should be based on:

• Inventory availability and lead time requirements
• Supplier preference and established procurement channels
• Cost considerations within approved vendor lists
• Manufacturing location and supply chain resilience

The KGM21ECG2D221FU (KYOCERA AVX) offers the highest current inventory level at 8641 units. The C0805C221F2GAC7800 (KEMET) features low ESL characteristics and the smallest maximum thickness at 0.035" (0.88mm), which may provide advantages in high-frequency applications or space-constrained designs. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. All three parts share identical capacitance (220 pF), tolerance (±1%), voltage rating (200V), temperature coefficient (C0G, NP0), and operating temperature range (-55°C to 125°C). They are electrically equivalent for general purpose applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts use the 0805 (2012 Metric) package with surface mount mounting type. Physical dimensions are compatible with standard PCB assembly processes. Minor thickness variations (0.88mm to 1.35mm maximum) do not affect PCB layout or assembly compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020. Moisture sensitivity level is 1 (unlimited) for all parts.

Q: Which substitute part should be selected for new designs?

A: Selection should be based on procurement strategy, inventory availability, and supplier relationships. All parts meet identical electrical and mechanical requirements. The KEMET part (C0805C221F2GAC7800) offers low ESL characteristics if high-frequency performance is a design consideration.

Q: Are there any physical dimension differences that affect assembly?

A: Physical dimensions are within acceptable tolerances for 0805 package specifications. The KEMET part has the smallest maximum thickness at 0.88mm, while the KYOCERA AVX part has the largest at 1.35mm. These variations are within standard PCB assembly tolerances and do not require design changes.
