Substitute Part Grouping Explanation

Substitution of the 1825WC562MAT1A is permissible with the 1825WC562KAT1A based on the following criteria:

Critical Parameters (Must Match):

• Capacitance: 5600 pF (identical)
• Voltage - Rated: 2500V (2.5kV) (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Package / Case: 1825 (4564 Metric) (identical)
• Physical Dimensions: 0.177" L x 0.252" W, 0.100" max thickness (identical)

Allowable Variation:

• Tolerance: ±20% (main part) vs. ±10% (substitute) — the substitute offers tighter tolerance, which is acceptable for applications designed for the main part's tolerance specification
• Packaging: Bulk vs. Tape & Reel (TR) — packaging format difference does not affect electrical or mechanical compatibility

Parameter Comparison

Engineering Selection Recommendations

Both the 1825WC562MAT1A and 1825WC562KAT1A are Active products manufactured by KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts should be based on:

Tolerance Requirements: The 1825WC562KAT1A provides ±10% tolerance compared to the ±20% tolerance of the 1825WC562MAT1A. Applications requiring tighter capacitance tolerance should specify the 1825WC562KAT1A.

Packaging Format: The 1825WC562MAT1A is supplied in bulk packaging, while the 1825WC562KAT1A is supplied in Tape & Reel (TR) format. Production environments utilizing automated pick-and-place equipment typically require Tape & Reel packaging.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent compliance posture for regulated applications.

Inventory Availability: The 1825WC562MAT1A has 1002 pieces in stock, while the 1825WC562KAT1A has 1784 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can the 1825WC562KAT1A replace the 1825WC562MAT1A in existing designs?

A: Yes. The 1825WC562KAT1A is electrically and mechanically compatible with the 1825WC562MAT1A. Both parts share identical capacitance (5600 pF), voltage rating (2500V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical dimensions (1825 package, 4.50mm x 6.40mm x 2.54mm max). The substitute offers tighter tolerance (±10% vs. ±20%), which is acceptable for applications designed for the main part.

Q: What is the difference between these two parts?

A: The primary differences are tolerance specification and packaging format. The 1825WC562KAT1A features ±10% tolerance versus ±20% for the 1825WC562MAT1A, and is supplied in Tape & Reel (TR) format rather than bulk packaging. All electrical and mechanical parameters remain identical.

Q: Are there any compatibility issues with PCB assembly?

A: No. Both parts use identical Surface Mount MLCC mounting technology and the 1825 (4564 Metric) package format. PCB footprints, reflow profiles, and assembly processes are interchangeable.

Q: Does the tighter tolerance of the 1825WC562KAT1A affect circuit performance?

A: The ±10% tolerance of the 1825WC562KAT1A is a subset of the ±20% tolerance specification of the 1825WC562MAT1A. Circuits designed for ±20% tolerance will operate within specification with the tighter tolerance substitute. Applications requiring specific tolerance bands should confirm the substitute falls within the required range.

Q: Which packaging format should I select?

A: Bulk packaging (1825WC562MAT1A) is suitable for manual assembly or small-volume production. Tape & Reel packaging (1825WC562KAT1A) is required for automated pick-and-place assembly systems used in high-volume manufacturing.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1825WC562MAT1A and 1825WC562KAT1A are ROHS3 Compliant with REACH Unaffected status, meeting regulatory requirements for restricted substance use.
