HT06BW104JN Equivalent & Substitute Parts

Part Overview

The HT06BW104JN is a 0.1 µF ceramic capacitor manufactured by KEMET, rated for 50V operation with X7R temperature coefficient characteristics. This radial through-hole component is designed for general-purpose applications requiring high-temperature performance across an operating 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 while offering active product status and current availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06BW104JN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.1 µF
• Tolerance: ±5%
• Temperature Coefficient: X7R
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)
• Physical footprint compatibility: 0.300" L x 0.150" W

Allowable Variation Parameters:

• Voltage Rating: Substitute parts may exceed the original 50V rating, provided the higher voltage does not create incompatibility with the circuit design
• Operating Temperature Range: Substitute parts may have a narrower upper temperature limit than the original -55°C ~ 200°C specification, provided the application does not require the full high-temperature range
• Product Status: Active status is preferred over obsolete status for long-term supply assurance
• Packaging Format: Tape & Reel (TR) is acceptable as a substitute for bulk packaging

The SR302C104JAATR1 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The SR302C104JAATR1 (KYOCERA AVX) qualifies as a direct electrical and mechanical substitute for the obsolete HT06BW104JN (KEMET) based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains identical capacitance (0.1 µF), tolerance (±5%), and temperature coefficient (X7R) specifications. The 200V voltage rating of the substitute exceeds the original 50V requirement, providing additional design margin without introducing circuit incompatibility. The X7R temperature coefficient ensures stable capacitance performance across the operating temperature range.

Mechanical Compatibility: Both parts share identical lead spacing (0.200"), footprint dimensions (0.300" L x 0.150" W), and radial through-hole mounting configuration. The substitute exhibits a maximum seated height of 0.360" compared to the original 0.300", representing a 0.060" increase. This dimensional difference must be evaluated against available board clearance in the target application.

Product Status and Compliance: The substitute part carries Active product status, ensuring long-term supply availability and manufacturing continuity. The SR302C104JAATR1 is ROHS3 Compliant and REACH Unaffected, providing regulatory compliance documentation suitable for industrial and commercial applications.

Temperature Range Consideration: The substitute operates across -55°C to 125°C, compared to the original -55°C to 200°C range. Applications requiring sustained operation above 125°C must retain the original HT06BW104JN specification or identify alternative high-temperature solutions.

Frequently Asked Questions (FAQ)

Q: Can the SR302C104JAATR1 be used as a direct replacement for the HT06BW104JN in all applications?

A: The SR302C104JAATR1 is electrically and mechanically compatible for applications operating within -55°C to 125°C. Applications requiring sustained operation above 125°C require alternative solutions. The 0.060" increase in seated height must be verified against available board clearance.

Q: Why does the substitute part have a higher voltage rating (200V vs. 50V)?

A: Higher voltage ratings do not create incompatibility in circuits designed for lower voltages. The 200V rating provides additional design margin and component robustness without affecting circuit performance. The capacitance, tolerance, and temperature coefficient remain identical.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designates a temperature coefficient of ±15% across the operating range, ensuring stable capacitance performance across temperature variations. Both the original and substitute parts share this specification, maintaining consistent circuit behavior.

Q: Are there packaging differences between the two parts?

A: The HT06BW104JN is supplied in bulk packaging, while the SR302C104JAATR1 is supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format selection depends on assembly process requirements and inventory management practices.

Q: What compliance certifications does the substitute part provide?

A: The SR302C104JAATR1 is ROHS3 Compliant and REACH Unaffected, providing regulatory compliance documentation for industrial, commercial, and consumer applications subject to environmental regulations.

Q: How does the seated height difference affect PCB design?

A: The substitute part's maximum seated height of 0.360" exceeds the original 0.300" by 0.060". PCB layouts with minimal clearance above component placement areas must be evaluated to ensure the additional height does not create mechanical interference with adjacent components or enclosure constraints.

Q: Is the SR302C104JAATR1 suitable for high-temperature applications above 125°C?

A: No. The SR302C104JAATR1 operates to a maximum of 125°C. Applications requiring sustained operation above 125°C must retain the original HT06BW104JN specification or identify alternative high-temperature ceramic capacitor solutions rated for extended temperature ranges.
