Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 18253E105MAT2A is determined by the following critical parameters:

• Capacitance Value: Must be 1 µF
• Tolerance: Must be ±20%
• Temperature Coefficient: Must be Z5U
• Package / Case: Must be 1825 (4564 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: May be equal to or greater than 25V (higher voltage ratings provide additional design margin)
• Operating Temperature Range: Must support 10°C ~ 85°C minimum
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The KEMET C1825C105M5UAC7800 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while providing an upgraded voltage rating of 50V, which is compatible with 25V circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the KYOCERA AVX 18253E105MAT2A and KEMET C1825C105M5UAC7800 are active production components with ROHS3 compliance and MSL 1 ratings. The KEMET substitute provides identical electrical performance with a higher voltage rating (50V vs. 25V), which is compatible with 25V circuit applications and offers additional safety margin. Physical dimensions are within acceptable tolerances for 1825 package specifications. Both components are suitable for general-purpose applications requiring stable capacitance across the 10°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C1825C105M5UAC7800 replace the KYOCERA AVX 18253E105MAT2A in a 25V circuit?

A: Yes. The KEMET part maintains identical capacitance (1 µF), tolerance (±20%), temperature coefficient (Z5U), and package (1825). The 50V rating is compatible with 25V applications and provides additional voltage margin.

Q: Are the physical dimensions compatible between these parts?

A: Yes. Both components use the 1825 (4564 Metric) package. Dimensional variations (0.180" vs. 0.177" length, 0.051" vs. 0.049" thickness) are within standard package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the KYOCERA AVX 18253E105MAT2A and KEMET C1825C105M5UAC7800 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) ratings.

Q: What is the operating temperature range for both parts?

A: Both components operate across 10°C to 85°C with Z5U temperature coefficient, ensuring stable capacitance performance within this range.

Q: Are there any restrictions on substituting between these manufacturers?

A: No. Both manufacturers produce MLCC components to industry standards. The electrical and mechanical specifications are equivalent, and both parts are in active production status.
