Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2220Y1K50471MXT is permissible when the following conditions are met:

Fixed Parameters (Non-Negotiable):

• Capacitance value: 470 pF
• Package / Case: 2220 (5750 Metric)
• Mounting Type: Surface Mount, MLCC
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Features: Soft Termination
• Manufacturer: Knowles Syfer
• Series: FlexiCap™

Variable Parameters (Allowed for Substitution):

• Voltage Rating: May be increased (higher voltage rating provides design margin)
• Tolerance: May be tightened (±10% is acceptable where ±20% is specified)
• Thickness: May vary within package constraints
• Inventory availability and product status

The substitute part 2220Y4K00471KXT maintains all fixed parameters while providing enhanced voltage rating (4000V vs 1500V) and improved tolerance (±10% vs ±20%), making it suitable for applications requiring higher voltage margin or tighter capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 2220Y1K50471MXT and 2220Y4K00471KXT are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current applications.

Selection between these parts depends on circuit voltage requirements:

• 2220Y1K50471MXT is appropriate for applications operating at or below 1500V with tolerance requirements of ±20%.
• 2220Y4K00471KXT is suitable for applications requiring higher voltage margin (up to 4000V) or where tighter capacitance tolerance (±10%) is specified. The reduced thickness (2.50mm vs 4.20mm) may provide design flexibility in space-constrained layouts.

Both parts maintain identical footprint dimensions (5.70mm x 5.00mm) and are pin-compatible for PCB assembly without layout modification.

Frequently Asked Questions (FAQ)

Q: Can 2220Y4K00471KXT replace 2220Y1K50471MXT in all applications?

A: Yes, provided the circuit design does not require the specific thickness of the original part. The substitute maintains identical capacitance, package footprint, and mounting characteristics while offering higher voltage rating and improved tolerance.

Q: What is the primary difference between these two parts?

A: The main differences are voltage rating (1500V vs 4000V), tolerance (±20% vs ±10%), and thickness (4.20mm vs 2.50mm). Capacitance value and package remain identical.

Q: Are there any PCB layout considerations when substituting?

A: No. Both parts use the same 2220 (5750 Metric) package with identical footprint dimensions (5.70mm x 5.00mm). PCB artwork and assembly procedures remain unchanged.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: Which part should be selected for new designs?

A: For new designs, 2220Y4K00471KXT is preferred when voltage requirements permit, as it provides design margin through higher voltage rating and improved tolerance specification.
