Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06CW473JN is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.047 µF
• Voltage rating: 100V minimum
• Tolerance: ±5%
• Mounting configuration: Through-hole radial

Mechanical Compatibility Requirements:

• Lead spacing: 0.200" (5.08mm)
• Lead style: Straight
• Package case: Radial

The substitute part C340C473J1G5TA satisfies all electrical and mechanical compatibility criteria. Both components share identical capacitance, voltage rating, tolerance, and lead spacing specifications. The primary distinction lies in temperature coefficient classification: the original part features X7R characteristics, while the substitute employs C0G/NP0 characteristics with a reduced operating temperature range of -55°C to 125°C.

Parameter Comparison

Engineering Selection Recommendations

C340C473J1G5TA as Primary Substitute:

The C340C473J1G5TA is an active production component manufactured by KEMET and represents the direct functional equivalent for the obsolete HT06CW473JN. Both parts maintain identical electrical specifications for capacitance (0.047 µF), voltage rating (100V), and tolerance (±5%). Mechanical compatibility is confirmed through matching lead spacing (0.200") and radial through-hole mounting configuration.

Temperature Coefficient Consideration:

The substitute employs C0G/NP0 temperature coefficient characteristics, which provide superior capacitance stability across temperature variations compared to X7R characteristics. The operating temperature range of the substitute extends from -55°C to 125°C, which encompasses standard industrial and commercial operating conditions. Applications requiring operation above 125°C must evaluate the reduced upper temperature limit against specific circuit requirements.

Compliance and Availability:

The C340C473J1G5TA carries active product status with 1310 units in current inventory, ensuring procurement continuity. The substitute is ROHS3 compliant and REACH unaffected, meeting contemporary regulatory requirements. The original HT06CW473JN, classified as obsolete with 849 units remaining in stock, should be transitioned to the active substitute for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can the C340C473J1G5TA directly replace the HT06CW473JN in existing circuit boards?

A: Yes, for applications operating within the -55°C to 125°C temperature range. Both components share identical lead spacing (0.200"), radial package configuration, and through-hole mounting requirements. PCB footprints are compatible without modification.

Q: What is the significance of the temperature coefficient difference between X7R and C0G/NP0?

A: X7R and C0G/NP0 represent different dielectric materials with distinct capacitance stability characteristics across temperature ranges. X7R maintains ±15% capacitance variation across its full operating range, while C0G/NP0 provides superior stability with minimal capacitance drift. For general-purpose applications, C0G/NP0 characteristics offer improved performance predictability.

Q: Are there applications where the HT06CW473JN cannot be substituted with the C340C473J1G5TA?

A: Substitution is not suitable for circuits requiring sustained operation above 125°C. The original HT06CW473JN supports operation to 200°C, while the substitute is rated to 125°C maximum. Applications with high-temperature requirements must retain the original part specification or identify alternative high-temperature ceramic capacitors.

Q: What is the physical size difference between these components?

A: The HT06CW473JN measures 0.300" L x 0.150" W with a maximum seated height of 0.300". The C340C473J1G5TA measures 0.290" L x 0.160" W with a maximum seated height of 0.494". Both components fit standard 0.200" lead spacing PCB holes. The substitute exhibits slightly greater height; verify clearance in confined mounting spaces.

Q: Is the C340C473J1G5TA available in the same packaging as the original part?

A: The C340C473J1G5TA is supplied in bulk packaging, whereas the original HT06CW473JN packaging specification was not provided. Both components are radial through-hole devices with identical lead configurations. Packaging format does not affect electrical or mechanical compatibility for circuit board assembly.

Q: What certifications apply to the substitute part?

A: The C340C473J1G5TA is ROHS3 compliant and REACH unaffected. Both certifications confirm compliance with current environmental and hazardous substance regulations applicable to electronic components in commercial and industrial applications.
