HT55CW562JC Equivalent & Substitute Parts

Part Overview

The HT55CW562JC is a 5600 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.

Lead Spacing	0.200" (5.08mm)	Critical for PCB footprint compatibility

Substitute Part Grouping Explanation

Substitution of the HT55CW562JC is based on strict electrical and mechanical parameter matching. The following criteria determine valid equivalents:

Electrical Parameters (Non-negotiable):

Capacitance value: 5600 pF
Voltage rating: 100V minimum
Temperature coefficient: X7R
Tolerance: ±5% or better

Mechanical Parameters (Non-negotiable):

Mounting type: Through Hole Radial
Package case: Radial configuration
Lead style: Straight leads

Operational Parameters:

Operating temperature range must support the application's thermal requirements

The SR151C562JAA from KYOCERA AVX meets all electrical specifications. However, physical dimensions and lead spacing differ, requiring evaluation for specific PCB layout compatibility.

Engineering Selection Recommendations

The SR151C562JAA from KYOCERA AVX provides electrical equivalence to the obsolete HT55CW562JC across all critical capacitive parameters: capacitance, voltage rating, temperature coefficient, and tolerance. Both components are rated for -55°C minimum operating temperature and feature X7R stability.

Electrical Compatibility: The SR151C562JAA is electrically suitable for applications currently using the HT55CW562JC, provided the operating temperature does not exceed 125°C. Applications requiring operation above 125°C cannot use this substitute, as the HT55CW562JC supports temperatures to 200°C.

Physical Compatibility: The SR151C562JAA has a smaller footprint (0.150" length vs. 0.200") and different lead spacing (0.100" vs. 0.200"). PCB layout modifications are required for direct substitution. The component will not fit existing HT55CW562JC footprints without redesign.

Compliance Status: The SR151C562JAA carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The HT55CW562JC's compliance status is not specified in the provided data.

Availability: The SR151C562JAA is in active production with 1085 pieces in stock, compared to the obsolete HT55CW562JC with 805 pieces remaining in inventory.

Frequently Asked Questions (FAQ)

Q: Can the SR151C562JAA be used as a direct drop-in replacement for the HT55CW562JC?

A: No. While electrically equivalent, the SR151C562JAA has different physical dimensions and lead spacing. The HT55CW562JC uses 0.200" lead spacing; the SR151C562JAA uses 0.100" lead spacing. PCB layout modification is required.

Q: What is the maximum operating temperature difference between these parts?

A: The HT55CW562JC operates to 200°C, while the SR151C562JAA operates to 125°C. For applications exceeding 125°C, the SR151C562JAA is not suitable.

Q: Are both parts RoHS compliant?

A: The SR151C562JAA is ROHS3 compliant. The HT55CW562JC's RoHS status is not specified in the available documentation.

Q: What is the lead spacing difference, and why does it matter?

A: The HT55CW562JC has 0.200" (5.08mm) lead spacing; the SR151C562JAA has 0.100" (2.54mm) lead spacing. Lead spacing determines PCB hole positioning. Mismatched spacing prevents mechanical insertion into existing footprints.

Q: Can I use the SR151C562JAA in new designs?

A: Yes, the SR151C562JAA is an active product suitable for new designs. Ensure your application's maximum operating temperature does not exceed 125°C and that your PCB layout accommodates the 0.100" lead spacing.

Q: What are the tolerance specifications for both parts?

A: Both the HT55CW562JC and SR151C562JAA have ±5% tolerance, ensuring equivalent capacitance accuracy.

Q: Is the SR151C562JAA available in sufficient quantity?

A: Yes, 1085 pieces are in stock as new original inventory, providing adequate supply for production requirements.
