HT11CN101FN Equivalent & Substitute Parts

Part Overview

The HT11CN101FN is a 100 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This axial through-hole component is designed for general-purpose applications requiring high-temperature stability across the -55°C to 200°C operating range. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT11CN101FN is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 100 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage Rating: 100V (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Operating Temperature Range: -55°C ~ 200°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Axial (exact match required)
• Lead Style: Straight (exact match required)

The ACA16D101FWS meets all substitution criteria as an active product from KEMET's equivalent series, maintaining identical electrical performance and environmental ratings while offering current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The ACA16D101FWS is the direct electrical equivalent for the obsolete HT11CN101FN. Both components share identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature specifications. The substitute part is manufactured by the same supplier (KEMET) and maintains equivalent regulatory compliance status (REACH Unaffected, EAR99 classification).

The primary physical difference is the body profile: the HT11CN101FN features a cylindrical axial body (0.100" diameter), while the ACA16D101FWS uses a square axial body (0.080" square cross-section). Both maintain the same 0.170" lead length. This dimensional variation requires verification of PCB layout compatibility, particularly in applications with space constraints or existing component placement patterns. Lead spacing and insertion hole sizing should be confirmed for the target application.

The ACA16D101FWS is currently in active production with documented inventory availability (772 pcs), providing supply continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the ACA16D101FWS be used as a direct replacement for the HT11CN101FN in existing designs?

A: Electrical substitution is complete. The ACA16D101FWS maintains identical capacitance (100 pF), tolerance (±1%), voltage rating (100V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 200°C). Physical compatibility requires verification of PCB layout, as the body profile differs (cylindrical vs. square cross-section). Lead length is identical at 0.170".

Q: What is the significance of the body profile difference between these parts?

A: The HT11CN101FN has a cylindrical axial body (0.100" diameter), while the ACA16D101FWS has a square axial body (0.080" square). Both are through-hole axial components with straight leads. The dimensional change may affect PCB routing, component spacing, and visual inspection procedures. Verify that the square profile accommodates existing PCB hole patterns and clearance requirements.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts share identical regulatory status: REACH Unaffected, EAR99 classification, and HTSUS code 8532.24.0040. No compliance barriers exist for substitution.

Q: Why is the HT11CN101FN classified as obsolete?

A: The HT11CN101FN is no longer in active production. The ACA16D101FWS represents KEMET's current equivalent offering within the same product family, providing continued access to 100 pF, 100V, C0G/NP0 axial ceramic capacitors with high-temperature capability.

Q: What is the moisture sensitivity level for these components?

A: The HT11CN101FN carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The ACA16D101FWS is listed as Not Applicable for MSL, consistent with ceramic capacitor technology. Both parts are suitable for standard handling and storage conditions.
