Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825WC562MAT9A is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 5600 pF
• Voltage Rating: 2500V (2.5kV)
• Temperature Coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation:

• Tolerance: The main part specifies ±20%. Substitute parts with tighter tolerance (±10%) are acceptable as they provide improved accuracy while maintaining functional compatibility.

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (required)
• REACH Status: REACH Unaffected (required)

The 1825WC562KAT1A qualifies as a direct substitute based on matching all critical parameters while offering improved tolerance specification (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1825WC562MAT9A and 1825WC562KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following criteria:

1825WC562MAT9A Selection:

• Applications where ±20% tolerance is acceptable
• Cost optimization when tighter tolerance is not required
• Current inventory availability (1155 pieces in stock)

1825WC562KAT1A Selection:

• Applications requiring improved capacitance accuracy (±10% tolerance)
• Designs where tighter tolerance reduces circuit performance variation
• Higher inventory availability (1784 pieces in stock)
• Tape & Reel packaging for automated assembly processes

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. The primary differentiation is tolerance specification and packaging format.

Frequently Asked Questions (FAQ)

Q: Can 1825WC562KAT1A replace 1825WC562MAT9A in existing designs?

A: Yes. The 1825WC562KAT1A is a direct substitute with identical capacitance, voltage rating, temperature coefficient, package footprint, and operating temperature range. The tighter tolerance (±10% versus ±20%) provides improved accuracy without requiring design modifications.

Q: What is the significance of the tolerance difference between these parts?

A: The main part specifies ±20% tolerance, meaning capacitance can vary from 4480 pF to 6720 pF. The substitute specifies ±10% tolerance, with capacitance ranging from 5040 pF to 6160 pF. For applications sensitive to capacitance variation, the substitute provides superior performance consistency.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1825 (4564 Metric) package with identical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm). PCB layout and assembly tooling require no modification.

Q: What is the difference between the packaging formats?

A: The 1825WC562MAT9A uses standard packaging, while the 1825WC562KAT1A is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and is standard for high-volume production.

Q: Are both parts compliant with current regulations?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. Identical electrical specifications, thermal characteristics, and mechanical compatibility ensure direct interchangeability. No circuit modifications, PCB redesign, or assembly process changes are required.
