Substitute Part Grouping Explanation

Substitution of the AFK228M10H32B-F is determined by the following key parameters that must match or be equivalent:

Capacitance: 2200 µF (nominal value)
Voltage Rating: 10 V (minimum rated voltage)
ESR and Impedance: 60 mOhms at 100 kHz (electrical performance specification)
Lifetime Rating: 5000 hours at 105°C (thermal endurance)
Operating Temperature Range: -55°C to 105°C
Case Dimensions: 0.492" diameter (12.50 mm) with seated height up to 0.551" (14.00 mm)

Engineering Selection Recommendations

Primary Direct Equivalents (Recommended for Automotive Applications):

EEE-FK1A222AQ and EEV-FK1A222Q (both Panasonic) are the preferred substitutes. Both parts maintain identical electrical specifications to the original AFK228M10H32B-F, including ESR, ripple current ratings, and thermal characteristics. Both are AEC-Q200 certified, suitable for automotive applications, and are currently in active production with established supply chains. EEE-FK1A222AQ is available in higher quantity inventory (14,389 pcs).

Secondary Equivalent (Space-Constrained Applications):

MAL215099414E3 (Vishay Beyschlag) meets all electrical specifications and carries AEC-Q200 certification for automotive use. The seated height of 0.650" (16.50 mm) exceeds the original specification by 0.099" (2.50 mm), requiring PCB layout verification to confirm mechanical clearance in the target application. High-frequency ripple current rating (1.007 A @ 100 kHz) is equivalent to the original specification.

General Purpose Alternative (Non-Automotive Applications):

EMVY100ARA222MKG5S (Chemi-Con Alchip™ MVY series) provides electrical equivalence with identical capacitance, voltage, tolerance, ESR, and thermal lifetime. The seated height of 0.630" (16.00 mm) exceeds the original by 0.079" (2.00 mm). This part lacks AEC-Q200 certification and is rated for general purpose applications. Low-frequency ripple current (712.5 mA @ 120 Hz) and high-frequency ripple current (950 mA @ 100 kHz) are reduced compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use EMVY100ARA222MKG5S in automotive applications?

A: EMVY100ARA222MKG5S is not AEC-Q200 certified and is specified for general purpose applications only. Automotive designs require AEC-Q200 certification. Use EEE-FK1A222AQ or EEV-FK1A222Q for automotive compliance.

Q: What is the impact of height differences between substitute parts?

A: Case height variation affects PCB layout clearance. The original AFK228M10H32B-F has a maximum seated height of 0.551" (14.00 mm). MAL215099414E3 (0.650") and EMVY100ARA222MKG5S (0.630") exceed this by 2.00 mm to 2.50 mm respectively. Verify available vertical clearance on the target board before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts meet ROHS3 compliance requirements.

Q: How do ripple current ratings affect component selection?

A: Ripple current capacity determines the maximum AC current the capacitor can safely carry without exceeding temperature limits. The original specification of 1.1 A @ 100 kHz is maintained by EEE-FK1A222AQ, EEV-FK1A222Q, and MAL215099414E3. EMVY100ARA222MKG5S has a lower rating of 950 mA @ 100 kHz; verify the circuit's ripple current requirement before substitution.

Q: What is the difference between EEE-FK1A222AQ and EEV-FK1A222Q?

A: Both Panasonic parts meet identical electrical specifications and dimensional requirements. EEE-FK1A222AQ is the FK series base model with higher inventory availability. EEV-FK1A222Q is a variant within the same FK series. Selection between these parts is driven by supplier availability and lead time requirements.

Q: Can I substitute based on capacitance and voltage rating alone?

A: No. ESR, ripple current rating, and thermal lifetime must also match. These parameters determine performance in bypass and decoupling applications. Height and land size must fit the PCB layout.

Q: Are land size differences significant?

A: Land size variations are minor across all substitute parts (ranging from 0.492" to 0.531" L × W in 12.50 mm to 15.00 mm dimensions). Standard assembly equipment accommodates these variations. Verify your PCB land pattern against the selected substitute part's datasheet to confirm compatibility.
