HT06AB224JN Equivalent & Substitute Parts Reference

Part Overview

The HT06AB224JN is a 0.22 µF ceramic capacitor rated at 25V with X7R temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring high-temperature operation across -55°C to 200°C. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement planning.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.22 µF	Must match exactly
Voltage Rating	25V	Minimum acceptable; higher ratings permissible
Tolerance	±5%	Must match or be tighter
Temperature Coefficient	X7R	Must match for thermal stability
Operating Temperature Range	-55°C ~ 200°C	Must meet or exceed
Mounting Type	Through Hole Radial	Must match for PCB compatibility
Lead Spacing	0.100" (2.54mm)	Critical for footprint compatibility

Substitute Part Grouping Explanation

Substitution eligibility for the HT06AB224JN is determined by the following mandatory parameters:

Matching Requirements:

Capacitance value: 0.22 µF (exact match required)
Temperature coefficient: X7R (exact match required)
Tolerance: ±5% or tighter
Mounting type: Through-hole radial configuration
Operating temperature range: Must support -55°C to 200°C minimum

Permissible Variations:

Voltage rating: May exceed 25V (higher ratings provide design margin)
Physical dimensions: May vary if lead spacing remains compatible with existing PCB footprints
Product status: Active or obsolete status does not disqualify substitution if electrical parameters align

The HP06CB224JC meets the core electrical requirements (0.22 µF, ±5%, X7R, -55°C to 200°C) but introduces a higher voltage rating (100V) and modified physical dimensions with increased lead spacing (0.200" vs. 0.100").

Parameter Comparison

Parameter	HT06AB224JN (Main Part)	HP06CB224JC (Substitute)	Compatibility Status
Manufacturer	KEMET	KEMET	Same manufacturer
Capacitance	0.22 µF	0.22 µF	Exact match
Tolerance	±5%	±5%	Exact match
Voltage Rating	25V	100V	Substitute rated higher
Temperature Coefficient	X7R	X7R	Exact match
Operating Temperature	-55°C ~ 200°C	-55°C ~ 200°C	Exact match
Mounting Type	Through Hole Radial	Through Hole Radial	Exact match
Lead Spacing	0.100" (2.54mm)	0.200" (5.08mm)	Different; requires PCB verification
Size/Dimension	0.200" L x 0.100" W (5.08mm x 2.54mm)	0.300" L x 0.125" W (7.62mm x 3.18mm)	Larger footprint
Product Status	Obsolete	Active	Substitute actively manufactured
RoHS Status	Non-compliant	Non-compliant	Same compliance status

Engineering Selection Recommendations

Primary Consideration: PCB Footprint Compatibility

The HP06CB224JC substitute introduces a critical physical difference: lead spacing increases from 0.100" to 0.200", and overall dimensions expand from 5.08mm x 2.54mm to 7.62mm x 3.18mm. Direct PCB substitution without layout modification is not feasible. This part functions as an electrical equivalent only and requires footprint redesign or manual rework for implementation.

Electrical Equivalence Confirmation

All core electrical parameters align between HT06AB224JN and HP06CB224JC:

Identical capacitance (0.22 µF) and tolerance (±5%)
Matching X7R temperature coefficient and operating range (-55°C to 200°C)
Voltage rating upgrade (100V vs. 25V) provides additional design margin without functional compromise

Product Status and Availability

The HP06CB224JC is classified as active product with 657 pieces in stock, ensuring procurement continuity. The HT06AB224JN obsolete status with 697 pieces available represents limited remaining inventory. For new designs or long-term production, the HP06CB224JC is the recommended electrical equivalent, contingent on PCB layout accommodation.

Compliance Considerations

Both parts maintain identical RoHS non-compliance and ECCN EAR99 classification. No compliance advantage exists between the two options.

Frequently Asked Questions (FAQ)

Q: Can HP06CB224JC be used as a direct drop-in replacement for HT06AB224JN?

A: No. While electrically equivalent, the HP06CB224JC has different lead spacing (0.200" vs. 0.100") and larger physical dimensions. Direct PCB substitution requires footprint modification or manual component rework.

Q: What are the key electrical parameters that make HP06CB224JC compatible with HT06AB224JN?

A: Capacitance (0.22 µF), tolerance (±5%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C) are identical. The 100V rating on the substitute exceeds the 25V requirement, providing design margin.

Q: Does the higher voltage rating (100V) of HP06CB224JC affect circuit performance?

A: No. A higher voltage-rated capacitor functions identically in circuits designed for lower voltages. The 100V rating provides additional safety margin and does not alter capacitance, tolerance, or temperature characteristics.

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

A: Both parts share identical RoHS non-compliance status and ECCN EAR99 classification. No compliance advantage exists between the two options.

Q: What is the lead spacing difference and why does it matter?

A: HT06AB224JN has 0.100" (2.54mm) lead spacing; HP06CB224JC has 0.200" (5.08mm) spacing. Lead spacing determines PCB hole positioning. Mismatched spacing prevents mechanical fit without PCB redesign or manual rework.

Q: Is HP06CB224JC available for procurement?

A: Yes. HP06CB224JC is classified as active product with 657 pieces in current inventory, ensuring supply continuity compared to the obsolete HT06AB224JN.
