HT55BN151KN Equivalent & Substitute Parts

Part Overview

The HT55BN151KN is a 150 pF ceramic capacitor rated at 50V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 200°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55BN151KN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 150 pF
• Tolerance: ±10%
• Voltage rating: 50V minimum
• Temperature coefficient: C0G or NP0
• Operating temperature range: -55°C to 200°C minimum
• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.200" (5.08mm)

The substitute part C052H151K5G5GA meets all mandatory parameters. Physical dimensions may vary within acceptable tolerances for through-hole radial packages, provided lead spacing remains at 0.200" (5.08mm) for PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

The C052H151K5G5GA is a direct functional equivalent to the HT55BN151KN. Both components are manufactured by KEMET and share identical electrical specifications: 150 pF capacitance, ±10% tolerance, 50V rating, and C0G/NP0 temperature coefficient across the -55°C to 200°C operating range.

The primary distinction is product status: the HT55BN151KN is obsolete, while the C052H151K5G5GA is active production. The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production runs.

Physical dimensions differ slightly (0.190" L x 0.090" W versus 0.200" L x 0.100" W), and the substitute features formed leads rather than straight leads. These dimensional variations remain within acceptable tolerances for through-hole radial package standards and do not affect electrical performance or PCB compatibility, provided lead spacing of 0.200" (5.08mm) is maintained for hole alignment.

Frequently Asked Questions (FAQ)

Q: Can C052H151K5G5GA be used as a direct replacement for HT55BN151KN in existing PCB designs?

A: Yes. Both components have identical lead spacing of 0.200" (5.08mm), matching PCB hole patterns. Electrical specifications are equivalent across all critical parameters: capacitance, tolerance, voltage rating, and temperature coefficient. Minor physical dimension differences do not affect form-fit-function compatibility.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The HT55BN151KN is obsolete and no longer in production. The C052H151K5G5GA is an active production part from the same manufacturer with identical electrical performance. For new designs or production continuity, the active substitute is the appropriate selection.

Q: Are there compliance differences between these parts?

A: The C052H151K5G5GA carries ROHS3 compliance and REACH unaffected status. The HT55BN151KN compliance information is not specified in available documentation. For applications requiring regulatory compliance certification, the C052H151K5G5GA meets current standards.

Q: Do the different lead styles (straight vs. formed) affect substitution?

A: No. Both lead styles are compatible with standard through-hole PCB assembly processes. Lead spacing remains constant at 0.200" (5.08mm), ensuring proper hole alignment and electrical connection.

Q: What are the key parameters that must match for substitution eligibility?

A: Capacitance (150 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 200°C), mounting type (through-hole), package type (radial), and lead spacing (0.200" / 5.08mm) must all match or exceed the original specification.
