Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC152MAT1A is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 1500 pF
• Temperature Coefficient: X7R
• Package / Case: 1808 (4520 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Flexible Parameters (May Vary):

• Voltage - Rated: May be equal or higher than 1000V
• Tolerance: May be equal or tighter than ±20%

The substitute part 1808GC152KAT1A meets all fixed parameter requirements while providing enhanced electrical characteristics through higher voltage rating (2000V) and improved tolerance (±10%), making it suitable for applications requiring greater voltage margin or tighter capacitance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC152MAT1A and 1808GC152KAT1A are Active products with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

The 1808AC152MAT1A is the primary selection for applications with 1000V voltage requirements and standard ±20% tolerance specifications.

The 1808GC152KAT1A serves as a direct substitute when higher voltage margin is required (2000V rating) or when tighter capacitance tolerance (±10%) is specified in the design. Both parts maintain identical physical dimensions, thermal characteristics, and moisture sensitivity ratings, ensuring mechanical and thermal compatibility in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 1808GC152KAT1A replace 1808AC152MAT1A in all applications?

A: Yes, provided the application circuit can accommodate the higher voltage rating (2000V vs. 1000V). The substitute part maintains identical capacitance, package dimensions, and operating temperature range.

Q: What is the significance of the tolerance difference (±20% vs. ±10%)?

A: The 1808GC152KAT1A provides tighter capacitance tolerance, resulting in more precise capacitance values across the production batch. Applications requiring strict capacitance specification benefit from this improved tolerance.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1808 (4520 Metric) package with dimensions of 0.181" L x 0.079" W (4.60mm x 2.00mm) and maximum thickness of 0.071" (1.80mm), ensuring direct PCB layout compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

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

A: Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient characteristics.
