HT06CW472JN Equivalent & Substitute Parts

Part Overview

The HT06CW472JN is a 4700 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET. This component is designed for general-purpose applications requiring high-temperature operation across the range of -55°C to 200°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06CW472JN is determined by strict electrical and mechanical parameter matching. The following criteria establish valid equivalency:

Electrical Parameters (Non-negotiable):

• Capacitance value must be 4700 pF
• Voltage rating must be 100V or higher
• Tolerance must be ±5% or tighter
• Temperature coefficient must be X7R

Mechanical Parameters (Non-negotiable):

• Mounting type must be Through Hole Radial
• Package case must be Radial
• Lead style must be Straight

Thermal Parameters:

• Operating temperature range must support the application's minimum requirement of -55°C to 200°C, or the substitute's range must encompass the actual operating conditions of the target application

The SR151C472JAR from KYOCERA AVX meets the electrical and mechanical requirements but operates only to 125°C maximum, which represents a thermal limitation compared to the original part's 200°C upper limit.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The SR151C472JAR provides full electrical equivalency in capacitance, voltage rating, tolerance, and temperature coefficient. Both components are rated for 100V with X7R characteristics and ±5% tolerance, ensuring identical electrical performance in circuit operation.

Thermal Limitation: The SR151C472JAR operates to a maximum of 125°C, compared to the HT06CW472JN's 200°C rating. Selection of this substitute is appropriate only for applications where the actual operating temperature does not exceed 125°C. Applications requiring sustained operation above 125°C require alternative sourcing.

Physical Incompatibility: The SR151C472JAR has significantly smaller physical dimensions (0.150" L x 0.100" W versus 0.300" L x 0.150" W) and reduced lead spacing (0.100" versus 0.200"). Direct PCB footprint substitution is not possible without redesign. The smaller package may be advantageous for space-constrained designs but requires PCB layout modification.

Product Status: The SR151C472JAR is an active product from KYOCERA AVX, ensuring ongoing availability and supply chain stability compared to the obsolete HT06CW472JN.

Compliance: Both components carry EAR99 ECCN classification and HTSUS code 8532.24.0060. The SR151C472JAR is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the SR151C472JAR be used as a direct drop-in replacement for the HT06CW472JN?

A: No. While electrical parameters are equivalent, the SR151C472JAR has different physical dimensions and lead spacing. Direct PCB substitution without layout modification is not possible. The SR151C472JAR measures 0.150" L x 0.100" W with 0.100" lead spacing, compared to the HT06CW472JN's 0.300" L x 0.150" W with 0.200" lead spacing.

Q: What is the thermal operating range difference, and does it matter?

A: The HT06CW472JN operates from -55°C to 200°C, while the SR151C472JAR operates from -55°C to 125°C. The 75°C difference in upper temperature limit is significant for high-temperature applications. If your circuit operates above 125°C, the SR151C472JAR is not suitable without thermal management modifications or alternative component selection.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components have 4700 pF capacitance, 100V voltage rating, ±5% tolerance, and X7R temperature coefficient. Electrical circuit behavior is equivalent when thermal constraints are satisfied.

Q: What mounting considerations apply to the SR151C472JAR?

A: Both parts are through-hole radial components with straight leads. The SR151C472JAR's smaller footprint (0.100" lead spacing versus 0.200") requires PCB redesign. Verify that the smaller package dimensions fit within your available board space and that lead spacing accommodates your hole pattern.

Q: Is the SR151C472JAR compliant with current regulations?

A: Yes. The SR151C472JAR is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. Both components share the same EAR99 ECCN classification.

Q: Why is the HT06CW472JN obsolete?

A: The HT06CW472JN is classified as obsolete by KEMET. The SR151C472JAR from KYOCERA AVX is an active product, ensuring continued availability and supply chain support for equivalent functionality.
