Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC472MAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4700 pF
• Tolerance: ±20%
• Voltage rating: 1500V (1.5kV) minimum
• Temperature coefficient: X7R
• Package designation: 1808 (4520 Metric)
• Mounting technology: Surface Mount, MLCC
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The identified substitute part C1808C472MFRAC7800 (KEMET) meets all mandatory electrical and mechanical parameters. Physical dimensions may vary within acceptable tolerances for the 1808 package class, and feature enhancements such as Low ESL do not disqualify substitution when core specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SC472MAT1A and C1808C472MFRAC7800 maintain active product status and satisfy identical electrical specifications for 4700 pF, 1500V, X7R ceramic capacitor applications. Both parts carry ROHS3 compliance and REACH Unaffected status, confirming regulatory alignment for industrial and commercial deployment.

The KEMET substitute (C1808C472MFRAC7800) offers reduced thickness (1.75mm vs. 2.20mm) and is available in Tape & Reel packaging format, which may provide advantages for automated assembly workflows. Inventory availability differs between manufacturers, with KEMET showing 2517 units in stock compared to 1150 units for the KYOCERA AVX original.

Selection between these parts should be based on supply chain requirements, packaging format compatibility with assembly equipment, and PCB layout constraints related to component height.

Frequently Asked Questions (FAQ)

Q: Can C1808C472MFRAC7800 be used as a direct replacement for 1808SC472MAT1A?

A: Yes. Both parts share identical electrical specifications (4700 pF, ±20%, 1500V, X7R, -55°C to 125°C) and are housed in the 1808 (4520 Metric) package. Physical dimensions vary slightly within package tolerance, with the KEMET part measuring 0.069" thickness versus 0.087" for the KYOCERA AVX original. This difference is acceptable for standard PCB assembly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires equivalence in capacitance (4700 pF), tolerance (±20%), voltage rating (1500V minimum), temperature coefficient (X7R), package class (1808), and mounting technology (Surface Mount MLCC). Compliance certifications (ROHS3, REACH) must also align.

Q: Does the thickness difference affect PCB layout?

A: The KEMET substitute is thinner (1.75mm vs. 2.20mm), which provides additional clearance for PCB routing and component placement. This does not create compatibility issues and may improve layout flexibility.

Q: Are both parts suitable for high voltage applications?

A: Yes. Both parts are rated for 1500V operation and include high voltage design features. The KEMET part additionally specifies Low ESL characteristics, which may provide performance benefits in high frequency or switching applications.

Q: What packaging formats are available?

A: The KYOCERA AVX original (1808SC472MAT1A) is supplied in standard packaging. The KEMET substitute (C1808C472MFRAC7800) is available in Tape & Reel format, which is optimized for automated pick-and-place assembly equipment.
