Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FG18X7R1H154KRT06 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.15 µF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.098" (2.50mm)
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 50V
• Packaging Format: Tape & Box (TB) or Cut Tape (CT)
• Product Status: Active or Not For New Designs
• Manufacturer: TDK Corporation

Two substitute parts meet these criteria:

1. FA18X7R1H154KRU06 — Direct electrical equivalent with identical voltage rating (50V), upgraded to Active product status with AEC-Q200 automotive qualification, supplied in Cut Tape packaging.

2. FG16X7R2A154KNT06 — Electrical equivalent with elevated voltage rating (100V), maintaining Active product status, supplied in Tape & Box packaging with larger physical dimensions to accommodate the higher voltage specification.

Parameter Comparison

Engineering Selection Recommendations

FA18X7R1H154KRU06 is the preferred direct substitute when:

• Identical electrical performance at 50V is required
• Active product status with long-term availability is prioritized
• AEC-Q200 automotive qualification adds value to the application
• Cut Tape packaging is compatible with assembly processes
• Physical dimensions and height remain unchanged from the original design

FG16X7R2A154KNT06 is the appropriate substitute when:

• Higher voltage margin (100V vs. 50V) is beneficial for circuit reliability
• Active product status with sustained manufacturing support is required
• Tape & Box packaging meets procurement specifications
• PCB layout can accommodate the larger physical dimensions (0.217" L x 0.138" W vs. 0.157" L x 0.098" W)
• Increased height (0.236" vs. 0.217") does not conflict with mechanical constraints

Both substitutes maintain identical lead spacing (0.098" / 2.50mm), enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can FA18X7R1H154KRU06 be used as a direct drop-in replacement for FG18X7R1H154KRT06?

A: Yes. Both parts share identical electrical specifications (0.15 µF, ±10%, 50V, X7R), operating temperature range (-55°C ~ 125°C), mounting type (through hole), package type (radial), and lead spacing (0.098" / 2.50mm). Physical dimensions and height are also identical. The primary difference is product status (Active vs. Not For New Designs) and packaging format (Cut Tape vs. Tape & Box).

Q: What is the key difference between FA18X7R1H154KRU06 and FG16X7R2A154KNT06?

A: The primary electrical difference is voltage rating: FA18X7R1H154KRU06 maintains 50V, while FG16X7R2A154KNT06 provides 100V. This voltage increase results in larger physical dimensions for FG16X7R2A154KNT06 (0.217" L x 0.138" W vs. 0.157" L x 0.098" W) and greater seated height (0.236" vs. 0.217"). Both maintain identical capacitance, tolerance, temperature coefficient, and lead spacing.

Q: Does the higher voltage rating of FG16X7R2A154KNT06 affect circuit performance?

A: No. A capacitor rated for higher voltage than required operates identically to one rated for the exact voltage needed. The 100V rating provides additional safety margin and does not alter capacitance, tolerance, or frequency response characteristics.

Q: Are there packaging considerations when switching between these substitutes?

A: Yes. FG18X7R1H154KRT06 and FG16X7R2A154KNT06 are supplied in Tape & Box (TB) format, while FA18X7R1H154KRU06 is supplied in Cut Tape (CT) format. Verify that your assembly equipment and procurement workflow support the selected packaging format.

Q: Will FG16X7R2A154KNT06 fit in the same PCB footprint as FG18X7R1H154KRT06?

A: Lead spacing is identical (0.098" / 2.50mm), so PCB footprint compatibility is maintained. However, the larger body dimensions (0.217" L x 0.138" W vs. 0.157" L x 0.098" W) and increased height (0.236" vs. 0.217") require verification that component placement does not conflict with adjacent components, traces, or mechanical structures.

Q: What does AEC-Q200 certification on FA18X7R1H154KRU06 indicate?

A: AEC-Q200 is an automotive electronics qualification standard. This certification indicates that FA18X7R1H154KRU06 meets automotive industry reliability and performance requirements. If your application requires automotive-grade components, FA18X7R1H154KRU06 is the appropriate choice.
