Substitute Part Grouping Explanation

Substitution of the 1808CC472MATME is permissible when the following conditions are met:

Mandatory Compatibility Criteria:

• Capacitance value remains 4700 pF
• Package format remains 1808 (4520 Metric)
• Mounting type remains Surface Mount, MLCC
• Physical dimensions remain 4.60mm L × 2.00mm W × 1.80mm thickness (Max)
• Temperature coefficient remains X7R
• Operating temperature range remains -55°C to 125°C or better
• RoHS3 compliance is maintained
• MSL rating remains 1 or better

Allowable Parameter Variations:

• Voltage rating may be equal to or greater than 630V
• Tolerance may be equal to or tighter than ±20%
• Packaging format may differ (e.g., Cut Tape vs. Digi-Reel)

The substitute part KGM42BR73A472KY meets all mandatory criteria while providing enhanced voltage rating (1000V vs. 630V) and improved tolerance (±10% vs. ±20%), making it suitable for applications requiring higher voltage margin or tighter capacitance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808CC472MATME and KGM42BR73A472KY maintain Active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these parts is determined by application voltage requirements and tolerance specifications:

Select 1808CC472MATME when:

• Circuit design operates at or below 630V
• Tolerance specification of ±20% is acceptable
• Cost optimization is prioritized

Select KGM42BR73A472KY when:

• Circuit design requires voltage margin above 630V or operates at 1000V
• Tighter tolerance of ±10% is required for circuit performance
• Higher reliability margin is specified for high-voltage applications

Both parts are manufactured by KYOCERA AVX and share identical mechanical compatibility, thermal characteristics, and regulatory compliance status. The substitute part represents an upgrade path for designs requiring enhanced electrical specifications without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can KGM42BR73A472KY be used as a direct replacement for 1808CC472MATME on existing PCBs?

A: Yes. Both parts share identical package format (1808), physical dimensions (4.60mm × 2.00mm × 1.80mm max), and mounting type (Surface Mount, MLCC). No PCB layout modifications are required.

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

A: The substitute part KGM42BR73A472KY provides higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%). Capacitance value and all other electrical and mechanical parameters remain identical.

Q: Are there any thermal or environmental differences?

A: No. Both parts feature X7R temperature coefficient with identical operating range (-55°C to 125°C), MSL 1 rating, and environmental compliance status.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For applications operating at or below 630V with ±20% tolerance acceptance, either part is suitable. For applications requiring 1000V rating or ±10% tolerance, KGM42BR73A472KY is the appropriate selection.

Q: Are packaging options different between these parts?

A: The main part is available in standard packaging, while the substitute is available in Cut Tape (CT) and Digi-Reel® formats. Both formats are compatible with standard pick-and-place assembly equipment.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification.
