HT05BN101KN Equivalent & Substitute Parts

Part Overview

The HT05BN101KN is a 100 pF ceramic capacitor rated at 50V with C0G/NP0 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 active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the HT05BN101KN is determined by strict equivalence across the following critical parameters:

Capacitance Value: 100 pF (exact match required)
Voltage Rating: 50V (minimum acceptable rating)
Temperature Coefficient: C0G/NP0 (required for temperature stability)
Operating Temperature Range: -55°C ~ 200°C (full range compatibility)
Mounting Configuration: Through Hole Radial (mechanical compatibility with PCB layout)
Lead Spacing: 0.100" (2.54mm) (PCB footprint compatibility)
Tolerance: ±10% (performance specification)

The ACR05B101KGS meets all electrical specifications and maintains mechanical compatibility with the original part. The primary distinction is the product status transition from obsolete to active, enabling continued procurement and supply chain reliability.

Engineering Selection Recommendations

The ACR05B101KGS serves as the active equivalent to the obsolete HT05BN101KN. Both components are manufactured by KEMET and share identical electrical specifications, including capacitance, voltage rating, temperature coefficient, and operating temperature range. The transition from HT05BN101KN to ACR05B101KGS is supported by the manufacturer's product line evolution within the industrial-grade C0G/NP0 ceramic capacitor category.

Product Status Consideration: The HT05BN101KN is classified as obsolete, while the ACR05B101KGS maintains active status with confirmed inventory availability (1111 pcs in stock). This status difference is the primary driver for substitution in new designs and ongoing system support.

Compliance Status: The ACR05B101KGS is RoHS non-compliant and REACH affected. Design teams must evaluate these compliance requirements against project specifications and regulatory obligations.

Lead Spacing Variance: The ACR05B101KGS specifies a lead spacing of 0.200" (5.08mm), whereas the HT05BN101KN specifies 0.100" (2.54mm). This difference requires PCB layout verification to ensure mechanical compatibility with existing footprints. Physical lead spacing modification or PCB redesign may be necessary for direct substitution in legacy applications.

Frequently Asked Questions (FAQ)

Q: Can the ACR05B101KGS be used as a direct replacement for the HT05BN101KN?

A: The ACR05B101KGS is electrically equivalent to the HT05BN101KN across all specified parameters: capacitance, voltage rating, temperature coefficient, and operating temperature range. However, the lead spacing differs (0.200" vs. 0.100"), requiring PCB footprint verification before implementation.

Q: What is the primary reason for substituting the HT05BN101KN?

A: The HT05BN101KN is classified as obsolete. The ACR05B101KGS is the active equivalent from KEMET, ensuring continued availability and supply chain reliability for both new designs and legacy system support.

Q: Are the physical dimensions identical between these parts?

A: The body dimensions are identical (0.200" L x 0.100" W, 5.08mm x 2.54mm), and the maximum seated height is identical (0.200", 5.08mm). The lead spacing differs: HT05BN101KN has 0.100" (2.54mm) spacing, while ACR05B101KGS has 0.200" (5.08mm) spacing.

Q: What compliance certifications apply to the ACR05B101KGS?

A: The ACR05B101KGS is classified as RoHS non-compliant and REACH affected. Design teams must assess these compliance statuses against project requirements and regulatory frameworks.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the HT05BN101KN and ACR05B101KGS operate across the identical temperature range of -55°C to 200°C with C0G/NP0 temperature coefficient, providing stable capacitance performance across this extended range.
