HT05BN301KN Equivalent & Substitute Parts

Part Overview

The HT05BN301KN is a 300 pF radial ceramic capacitor manufactured by KEMET, rated for 50V operation with C0G/NP0 temperature coefficient characteristics. This component is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 200°C). The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT05BN301KN is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value within ±10% tolerance band (acceptable range: 270 pF to 330 pF)
• Voltage rating equal to or greater than 50V
• Temperature coefficient C0G/NP0 for stable performance across the operating temperature range
• Operating temperature range minimum of -55°C to 200°C

Mechanical Compatibility Requirements:

• Through-hole radial package configuration
• Lead spacing compatible with 0.100" (2.54mm) PCB hole patterns
• Radial lead style for standard component insertion

Compliance and Status:

• Active product status for ongoing availability
• RoHS and REACH compliance for current manufacturing standards

The C052H331K5G5GA meets the electrical requirements through its 330 pF capacitance (within the ±10% tolerance band of the original 300 pF specification), matching voltage rating, temperature coefficient, and operating temperature range. However, mechanical differences in lead spacing and lead style require evaluation for specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

The C052H331K5G5GA serves as an electrical equivalent to the HT05BN301KN based on matching voltage rating, temperature coefficient, operating temperature range, and capacitance value within the specified tolerance band. Both components are manufactured by KEMET and share identical electrical performance characteristics for general-purpose applications.

The substitute part is classified as active product status, ensuring ongoing availability and manufacturing support compared to the obsolete HT05BN301KN. The C052H331K5G5GA carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production.

Mechanical differences exist in lead spacing (0.200" versus 0.100") and lead style (formed leads versus straight leads). These differences require PCB layout evaluation to determine compatibility with existing hole patterns and component insertion processes. The substitute part's formed leads and increased lead spacing may necessitate PCB redesign or manual lead adjustment for direct replacement in legacy applications.

Frequently Asked Questions (FAQ)

Q: Can the C052H331K5G5GA directly replace the HT05BN301KN in all applications?

A: Electrical substitution is valid based on matching voltage rating, temperature coefficient, and operating temperature range. The 330 pF capacitance falls within the ±10% tolerance band of the original 300 pF specification. However, mechanical compatibility depends on PCB hole spacing and lead insertion requirements. The substitute part features 0.200" lead spacing compared to the original 0.100" spacing, requiring PCB layout verification.

Q: What is the capacitance tolerance relationship between 300 pF and 330 pF?

A: The 300 pF part with ±10% tolerance has an acceptable range of 270 pF to 330 pF. The 330 pF substitute falls at the upper tolerance limit of the original specification, making it electrically equivalent for general-purpose applications where the tolerance band is acceptable.

Q: Are there compliance differences between the main part and substitute?

A: The HT05BN301KN product status is listed as obsolete with unspecified compliance documentation. The C052H331K5G5GA is an active product with ROHS3 compliance and REACH unaffected status, meeting current manufacturing and environmental standards.

Q: What are the physical dimension differences?

A: The HT05BN301KN measures 0.200" L x 0.100" W with 0.100" lead spacing and straight leads. The C052H331K5G5GA measures 0.190" L x 0.090" W with 0.200" lead spacing and formed leads. These differences affect PCB footprint compatibility and component insertion methods.

Q: Is the substitute part suitable for high-temperature applications?

A: Both parts operate across the identical temperature range of -55°C to 200°C with C0G/NP0 temperature coefficient, providing stable capacitance performance in high-temperature environments. The substitute part is suitable for applications requiring this temperature range.
