Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55BN220KN is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 22 pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G or NP0
• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.200" (5.08mm)
• Lead style: Straight

Substitution Classification:

Parametric Equivalent: ACR05B220KGS maintains identical electrical specifications (22 pF ±10%, 50V, C0G/NP0) and mechanical dimensions (0.200" L x 0.100" W, 0.200" height, 0.200" lead spacing). This part is manufactured by KEMET and carries active product status.

Similar Equivalent: 1C20C0G220J050B provides electrical compatibility (22 pF, 50V, C0G/NP0) with mechanical variations. This Vishay Beyschlag/Draloric/BC Components part features tighter tolerance (±5% versus ±10%) and different physical dimensions (0.200" L x 0.125" W, 0.250" height). Operating temperature range differs at -55°C to 125°C versus the original -55°C to 200°C specification.

Parameter Comparison

Engineering Selection Recommendations

ACR05B220KGS (Parametric Equivalent - Recommended Primary Substitute)

The ACR05B220KGS is the optimal direct replacement for the HT55BN220KN. Both parts are manufactured by KEMET and share identical electrical specifications (22 pF ±10%, 50V, C0G/NP0) and mechanical dimensions. The ACR05B220KGS maintains the full operating temperature range of -55°C to 200°C, ensuring compatibility with high-temperature applications. This part carries active product status and is available in bulk packaging with 1024 units in stock. The ACR05B220KGS is classified as RoHS non-compliant and REACH Affected, matching the regulatory profile of the original component.

1C20C0G220J050B (Similar Equivalent - Conditional Substitute)

The 1C20C0G220J050B from Vishay Beyschlag/Draloric/BC Components provides electrical compatibility with the following considerations. This part maintains the 22 pF capacitance, 50V rating, and C0G/NP0 temperature coefficient. The tolerance is tighter at ±5% compared to the original ±10%, which is advantageous for precision applications. However, the operating temperature range is limited to -55°C to 125°C, which does not support the full high-temperature capability of the original specification. Physical dimensions differ slightly (0.200" L x 0.125" W versus 0.200" L x 0.100" W, and 0.250" height versus 0.200" height), requiring verification of PCB layout clearance. This part is ROHS3 Compliant and REACH Unaffected, offering improved regulatory compliance. The 1C20C0G220J050B is suitable for applications where the reduced temperature range is acceptable and PCB space permits the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can the ACR05B220KGS directly replace the HT55BN220KN without circuit modification?

A: Yes. The ACR05B220KGS is a parametric equivalent with identical capacitance (22 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and mechanical dimensions. No circuit modifications are required. Both parts feature 0.200" lead spacing and straight leads, ensuring direct PCB compatibility.

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

A: The ACR05B220KGS is a direct parametric equivalent manufactured by KEMET with identical specifications and dimensions. The 1C20C0G220J050B is a similar equivalent from Vishay with tighter tolerance (±5% versus ±10%) but a reduced operating temperature range (-55°C to 125°C versus -55°C to 200°C) and larger physical dimensions (0.250" height versus 0.200" height).

Q: Is the 1C20C0G220J050B suitable for high-temperature applications?

A: The 1C20C0G220J050B has a maximum operating temperature of 125°C, which is lower than the original HT55BN220KN specification of 200°C. This part is not suitable for applications requiring the full high-temperature range. Verify application temperature requirements before selection.

Q: Will the 1C20C0G220J050B fit in the same PCB footprint?

A: The 1C20C0G220J050B has different physical dimensions. The width is 0.125" versus 0.100" and the seated height is 0.250" versus 0.200". Lead spacing remains at 0.200". Verify PCB layout clearance, particularly for height and width constraints, before substitution.

Q: What is the tolerance difference between the substitute parts?

A: The HT55BN220KN and ACR05B220KGS both have ±10% tolerance. The 1C20C0G220J050B has ±5% tolerance, which is tighter and may provide improved circuit performance in precision applications.

Q: Are there regulatory compliance differences between the substitutes?

A: The ACR05B220KGS is RoHS non-compliant and REACH Affected, matching the original part profile. The 1C20C0G220J050B is ROHS3 Compliant and REACH Unaffected, offering improved regulatory compliance for new designs or applications with stricter compliance requirements.

Q: What inventory availability exists for these substitutes?

A: The ACR05B220KGS has 1024 units in stock. The 1C20C0G220J050B has 10629 units in stock, providing greater availability for high-volume requirements.
