HT14CB473KN Equivalent & Substitute Parts

Part Overview

The HT14CB473KN is a 0.047 µF ceramic capacitor manufactured by KEMET, rated for 100V operation with X7R temperature coefficient characteristics. This axial through-hole component is designed for general-purpose applications requiring high-temperature performance across the -55°C to 200°C operating range. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and design continuity.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.047 µF	Must match exactly
Voltage Rating	100V	Must match or exceed
Temperature Coefficient	X7R	Must match for temperature stability
Mounting Type	Through Hole Axial	Must match for PCB compatibility
Operating Temperature Range	-55°C ~ 200°C	Substitute must support application requirements
Tolerance	±10%	Substitute tolerance must be equal or tighter

Substitute Part Grouping Explanation

Substitution of the HT14CB473KN is based on the following critical parameters:

Mandatory Match Criteria:

Capacitance value: 0.047 µF (exact match required)
Voltage rating: 100V minimum
Temperature coefficient: X7R (ensures equivalent capacitance stability across temperature)
Mounting configuration: Through-hole axial (PCB footprint compatibility)

Acceptable Variation Criteria:

Tolerance: Substitute tolerance of ±5% is tighter than the original ±10%, making it acceptable
Operating temperature range: Substitute range of -55°C ~ 125°C covers the lower portion of the original range; suitability depends on application maximum temperature requirement
Physical dimensions: Minor variations in diameter and length are acceptable provided lead spacing and mounting holes align with PCB design

The SA301C473JAR from KYOCERA AVX meets all mandatory criteria and represents a direct functional equivalent for applications not requiring operation above 125°C.

Engineering Selection Recommendations

SA301C473JAR Selection Criteria:

The SA301C473JAR is suitable as a direct substitute for the HT14CB473KN when the following conditions are met:

Temperature Requirement: The application maximum operating temperature does not exceed 125°C. If sustained operation above 125°C is required, this substitute is not appropriate.
Tolerance Requirement: The tighter ±5% tolerance of the SA301C473JAR is acceptable and provides improved capacitance stability compared to the original ±10% specification.
Physical Fit: The smaller physical dimensions (0.150" Dia x 0.290" L versus 0.155" Dia x 0.400" L) must be verified against PCB layout constraints. The reduced size may provide layout benefits but requires confirmation that lead spacing and mounting hole alignment are compatible.
Compliance Status: The SA301C473JAR is an active production part with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment.
Packaging: The substitute is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SA301C473JAR replace the HT14CB473KN in all applications?

A: No. The SA301C473JAR is suitable only for applications where the maximum operating temperature does not exceed 125°C. The original HT14CB473KN supports operation to 200°C. Verify your application's temperature requirements before substitution.

Q: What does the X7R temperature coefficient mean?

A: X7R indicates a ceramic capacitor with a temperature coefficient of ±15% over the operating temperature range. Both parts share this specification, ensuring equivalent capacitance stability characteristics across their respective temperature ranges.

Q: Are the physical dimensions critical for substitution?

A: Yes. While the SA301C473JAR is physically smaller, the lead spacing and mounting hole positions must align with your PCB design. Measure the lead-to-lead distance and verify compatibility with existing PCB footprints before substitution.

Q: Why is the SA301C473JAR tolerance tighter (±5% vs ±10%)?

A: Tighter tolerance indicates improved manufacturing precision. The ±5% tolerance of the SA301C473JAR is a superior specification that provides better capacitance consistency. This is an advantage for applications sensitive to capacitance variation.

Q: Is the SA301C473JAR RoHS compliant?

A: Yes. The SA301C473JAR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original HT14CB473KN compliance status is not specified in the provided data.

Q: What is the difference between Tape & Reel and other packaging formats?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly. If your manufacturing process uses manual insertion or requires different packaging, alternative sourcing may be necessary.

Q: Can I use the SA301C473JAR if my circuit operates at 150°C?

A: No. The SA301C473JAR maximum operating temperature is 125°C. Operation at 150°C exceeds the component's rated specification and may result in capacitance drift or failure. The original HT14CB473KN supports 150°C operation.
