Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06BN221KN is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 220 pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0 (ensures stable capacitance across temperature range)
• Operating temperature range: -55°C to 200°C minimum

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.200" (5.08mm)

Tolerance Consideration: The HT06BN221KN specifies ±10% tolerance. Substitute parts with tighter tolerance (±5%) are electrically compatible and represent an improvement in precision without affecting circuit functionality.

The ACR05B221JGS meets all critical electrical and mechanical parameters while offering improved tolerance specification and active product status.

Engineering Selection Recommendations

ACR05B221JGS as Primary Substitute:

The ACR05B221JGS is the direct functional equivalent for HT06BN221KN replacement. Selection is based on the following engineering criteria:

1. Electrical Equivalence: Identical capacitance (220 pF), voltage rating (50V), and temperature coefficient (C0G/NP0) ensure direct circuit compatibility without design modification.

2. Mechanical Compatibility: Matching through-hole radial package configuration and 0.200" lead spacing enable direct PCB footprint compatibility.

3. Product Status: ACR05B221JGS maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete HT06BN221KN.

4. Tolerance Improvement: The ±5% tolerance specification of ACR05B221JGS provides superior precision compared to the ±10% tolerance of the original part, representing a technical enhancement without functional impact.

5. Compliance Considerations: ACR05B221JGS is REACH Affected and RoHS non-compliant. Design teams must verify compliance requirements against system-level specifications before implementation.

6. Certification Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications, maintaining regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can ACR05B221JGS be used as a direct replacement for HT06BN221KN without PCB modification?

A: Yes. Both components share identical lead spacing (0.200"), radial package configuration, and through-hole mounting type. Direct PCB footprint compatibility is confirmed.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The ACR05B221JGS tolerance of ±5% is tighter than the HT06BN221KN tolerance of ±10%. This represents improved manufacturing precision. In circuits where capacitance tolerance is non-critical, both specifications are functionally equivalent. In precision applications, the tighter tolerance of ACR05B221JGS may provide performance benefits.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across -55°C to 200°C, ensuring equivalent thermal performance in high-temperature applications.

Q: What does the C0G/NP0 temperature coefficient mean for substitution?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic, indicating minimal capacitance variation across the operating temperature range. Both parts maintain this specification, ensuring equivalent frequency stability and temperature performance.

Q: Why is HT06BN221KN classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. ACR05B221JGS maintains active production status, making it the appropriate choice for new designs and ongoing component procurement.

Q: Are there any compliance differences between the two parts?

A: ACR05B221JGS is marked as RoHS non-compliant and REACH Affected. Design teams must verify these compliance statuses against system-level requirements before selecting this substitute.

Q: What is the physical size difference between these components?

A: HT06BN221KN dimensions are 0.300" L x 0.150" W (7.62mm x 3.81mm) with 0.300" seated height. ACR05B221JGS dimensions are 0.200" L x 0.100" W (5.08mm x 2.54mm) with 0.200" seated height. The substitute is physically smaller while maintaining identical electrical performance and lead spacing.
