HT55BN101KN Equivalent & Substitute Parts

Part Overview

The HT55BN101KN is a 100 pF ceramic capacitor rated at 50V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for high-temperature applications with an operating range of -55°C to 200°C. The part is currently obsolete, necessitating identification of equivalent alternatives that maintain electrical and mechanical compatibility for existing designs or production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55BN101KN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 pF
• Voltage Rating: 50V
• Temperature Coefficient: C0G/NP0
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)
• Lead Style: Straight

Allowable Variations:

• Tolerance: ±10% or tighter (±5% acceptable)
• Operating Temperature Range: Must support minimum -55°C to 200°C or equivalent high-temperature capability
• Physical dimensions: Minor variations in length and height permitted if lead spacing and mounting compatibility remain unchanged

Two substitute parts meet these criteria and are classified as follows:

Parametric Equivalent: ACR05B101KGS (KEMET) — Identical electrical specifications and mechanical footprint with active product status.

Similar Equivalent: 1C20C0G101J050B (Vishay Beyschlag/Draloric/BC Components) — Meets all mandatory parameters with tighter tolerance and active status; minor dimensional variation in body width and height.

Engineering Selection Recommendations

ACR05B101KGS (KEMET) — Recommended for Direct Replacement:

The ACR05B101KGS is the primary substitute for the obsolete HT55BN101KN. This part maintains identical electrical specifications (100 pF, ±10%, 50V, C0G/NP0) and mechanical footprint (0.200" lead spacing, 0.200" body length, 0.100" body width). Both components share the same operating temperature range (-55°C to 200°C) and are manufactured by KEMET. The ACR05B101KGS holds active product status with 1111 pieces in stock, ensuring availability for production and replacement applications. The primary consideration is RoHS compliance status: the ACR05B101KGS is RoHS non-compliant and REACH Affected, which may impact regulatory requirements depending on application jurisdiction and end-use classification.

1C20C0G101J050B (Vishay Beyschlag/Draloric/BC Components) — Alternative for Compliance-Driven Applications:

The 1C20C0G101J050B serves as an alternative substitute when regulatory compliance is a primary concern. This part meets all mandatory electrical parameters (100 pF, 50V, C0G/NP0) and maintains lead spacing compatibility (0.200"). The tolerance is tighter at ±5%, providing improved capacitance stability. The component is ROHS3 Compliant and REACH Unaffected, addressing environmental and regulatory requirements. However, two limitations apply: the operating temperature range is -55°C to 125°C (not extending to 200°C), and physical dimensions differ slightly (0.125" body width and 0.250" seated height versus 0.100" and 0.200" respectively). These dimensional differences may require PCB layout verification to confirm clearance compatibility, particularly in space-constrained applications. This part is active with 4151 pieces in stock.

Selection Criteria Summary:

• Use ACR05B101KGS for direct electrical and mechanical replacement when RoHS/REACH compliance is not a constraint.
• Use 1C20C0G101J050B when ROHS3 compliance and REACH exemption are required, provided the -55°C to 125°C operating range is acceptable for the application.
• Verify PCB layout clearance for the 1C20C0G101J050B due to increased body width and height.

Frequently Asked Questions (FAQ)

Q: Can the ACR05B101KGS be used as a direct drop-in replacement for the HT55BN101KN?

A: Yes. The ACR05B101KGS is electrically and mechanically identical to the HT55BN101KN. Both components have 100 pF capacitance, ±10% tolerance, 50V rating, C0G/NP0 temperature coefficient, -55°C to 200°C operating range, and identical lead spacing (0.200"). Physical dimensions are also identical, enabling direct PCB substitution without layout modifications.

Q: What is the key difference between the two substitute parts?

A: The ACR05B101KGS (KEMET) is electrically and mechanically identical to the original part. The 1C20C0G101J050B (Vishay) offers tighter tolerance (±5% vs. ±10%), ROHS3 compliance, and REACH exemption, but has a reduced operating temperature range (-55°C to 125°C instead of -55°C to 200°C) and slightly larger physical dimensions (0.125" width and 0.250" height).

Q: Will the 1C20C0G101J050B fit in the same PCB footprint as the HT55BN101KN?

A: The lead spacing is identical (0.200"), so the component will mount to the same holes. However, the body dimensions differ: the 1C20C0G101J050B is wider (0.125" vs. 0.100") and taller (0.250" vs. 0.200"). Verify that the PCB layout provides sufficient clearance around the component location to accommodate these dimensional differences.

Q: Is the operating temperature range difference between the substitutes significant?

A: This depends on application requirements. The HT55BN101KN and ACR05B101KGS both support -55°C to 200°C operation. The 1C20C0G101J050B is limited to -55°C to 125°C. If the application requires operation above 125°C, the 1C20C0G101J050B is not suitable; use the ACR05B101KGS instead.

Q: What does RoHS non-compliant mean for the ACR05B101KGS?

A: RoHS non-compliance indicates the component may contain restricted substances (lead, cadmium, mercury, etc.) above specified thresholds. This status affects regulatory eligibility in jurisdictions with RoHS requirements (EU, California, etc.). Verify compliance requirements for your application and end market before selecting this part.

Q: Are both substitute parts currently available?

A: Yes. The ACR05B101KGS has 1111 pieces in stock, and the 1C20C0G101J050B has 4151 pieces in stock, both listed as active products with new original inventory.

Q: Can I use the 1C20C0G101J050B in a high-temperature application requiring 200°C operation?

A: No. The 1C20C0G101J050B is rated only to 125°C maximum operating temperature. For applications requiring 200°C operation, use the ACR05B101KGS, which maintains the full -55°C to 200°C range of the original HT55BN101KN.
