Substitute Part Grouping Explanation

Substitution eligibility for the 1825HC472MAT3A is determined by strict alignment of the following critical parameters:

Core Substitution Criteria:

• Capacitance: 4700 pF (exact match required)
• Voltage Rating: 3000V (3kV) minimum (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm) (exact match required)
• Thickness: 0.100" (2.54mm) maximum (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute acceptable as tighter tolerance)
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable based on procurement and assembly requirements

The identified substitutes maintain identical electrical performance and mechanical compatibility while offering alternative tolerance specifications and packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

1825HC472KAT1A (Upgrade Substitute)

This part offers tighter capacitance tolerance (±10% versus ±20%), providing improved circuit performance where capacitance accuracy is critical. All electrical and mechanical parameters remain identical to the main part. This substitute is suitable for applications requiring enhanced tolerance specifications while maintaining full compatibility with existing designs. Product status is Active with full ROHS3 compliance.

1825HC472MAT1A (Parametric Equivalent)

This part maintains identical electrical specifications and tolerance (±20%) as the main part 1825HC472MAT3A. The primary distinction is packaging format: supplied in Tape & Reel (TR) configuration versus Cut Tape (CT) & Digi-Reel® for the main part. Selection between these parts depends on assembly line requirements and procurement volume. Product status is Active with full ROHS3 compliance.

Selection Basis:

All three parts share identical core electrical performance (4700 pF, 3000V, X7R, -55°C ~ 125°C), mechanical compatibility (1825 package, 4.50mm x 6.40mm x 2.54mm), and regulatory compliance (ROHS3, MSL 1). Substitution decisions should be based on tolerance requirements, packaging format availability, and inventory status rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825HC472MAT3A in my circuit?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical capacitance (4700 pF), voltage rating (3000V), temperature coefficient (X7R), package (1825), and operating temperature range (-55°C ~ 125°C). The tighter tolerance (±10% versus ±20%) makes it suitable for all applications where the main part is used, with improved capacitance accuracy.

Q: What is the difference between 1825HC472MAT1A and 1825HC472MAT3A?

A: Both parts are parametric equivalents with identical electrical specifications and ±20% tolerance. The difference is packaging format: 1825HC472MAT1A is supplied in Tape & Reel (TR) format, while 1825HC472MAT3A is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical performance and mechanical fit are identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—1825HC472MAT3A, 1825HC472KAT1A, and 1825HC472MAT1A—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes, provided your assembly process supports the packaging format of the substitute part. All three parts have identical mechanical dimensions (0.177" L x 0.252" W x 0.100" max thickness) and Surface Mount MLCC mounting type, ensuring PCB footprint compatibility.

Q: Which substitute should I choose for high-precision applications?

A: The 1825HC472KAT1A offers ±10% tolerance compared to ±20% for the other parts, making it the appropriate choice for circuits where capacitance accuracy directly impacts performance.

Q: Are there inventory or lead time considerations for these substitutes?

A: Inventory levels vary: 1825HC472MAT3A (879 Pcs), 1825HC472KAT1A (2400 Pcs), and 1825HC472MAT1A (629 Pcs). Availability should be confirmed with your supplier for current procurement timelines.
