Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFK227M2AR44B-F is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value of 220 µF (exact match required)
• Voltage rating of 100 V (minimum requirement)
• Tolerance of ±20% or tighter
• Operating temperature range of -55°C to 105°C (minimum coverage required)
• Lifetime rating of 5000 Hrs @ 105°C (minimum requirement)
• Polarization type: Polar (required for electrolytic capacitors)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.709" Dia (18.00mm) × 0.669" H (17.00mm) (exact match required)
• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory compliance)

The identified substitute parts meet all these criteria and are manufactured by Panasonic Electronic Components, a qualified automotive-grade supplier.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic substitute parts (EEE-FK2A221AM and EEV-FK2A221M) are direct functional equivalents to the discontinued AFK227M2AR44B-F based on the following engineering criteria:

Electrical Compatibility: All three parts share identical capacitance (220 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and lifetime specification (5000 Hrs @ 105°C). The impedance values of the Panasonic substitutes (153 mOhms) are within acceptable tolerance of the original part (150 mOhms), with a variance of 2%. Ripple current specifications are identical across all three parts.

Mechanical Compatibility: The substitute parts maintain identical physical dimensions (0.709" Dia × 0.669" H), package type (Radial, Can - SMD), and mounting type (Surface Mount), ensuring direct PCB footprint compatibility without design modification.

Compliance and Qualification: Both substitute parts carry AEC-Q200 automotive qualification and RoHS3 compliance, meeting the regulatory and quality requirements of the original part. MSL rating of 1 (Unlimited) matches the original specification.

Availability and Product Status: The original AFK227M2AR44B-F is discontinued at DiGi Electronics. Both Panasonic substitutes are active products with substantial inventory availability. EEV-FK2A221M offers significantly higher inventory (1,000,300 pcs) compared to EEE-FK2A221AM (4,214 pcs).

Packaging Considerations: EEE-FK2A221AM is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. EEV-FK2A221M is supplied in Cut Tape (CT) & Digi-Reel® format, offering flexibility for both manual and automated assembly. Selection between these two should be based on production assembly requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK2A221AM or EEV-FK2A221M be used as direct replacements for AFK227M2AR44B-F without PCB modification?

A: Yes. Both Panasonic parts are direct mechanical and electrical equivalents. They share identical physical dimensions (0.709" Dia × 0.669" H), package type (Radial, Can - SMD), and electrical specifications (220 µF, 100 V, ±20% tolerance). No PCB layout changes are required.

Q: Are the substitute parts qualified for automotive applications?

A: Yes. Both EEE-FK2A221AM and EEV-FK2A221M carry AEC-Q200 automotive qualification, matching the original part's automotive rating. Both are suitable for automotive, bypass, and decoupling applications.

Q: What is the difference between EEE-FK2A221AM and EEV-FK2A221M?

A: The primary difference is packaging format. EEE-FK2A221AM is supplied in Tape & Reel (TR) format, while EEV-FK2A221M is supplied in Cut Tape (CT) & Digi-Reel® format. Electrically and mechanically, both parts are identical. Selection depends on assembly process requirements and inventory management preferences.

Q: Do the substitute parts meet RoHS3 compliance?

A: Yes. Both EEE-FK2A221AM and EEV-FK2A221M are RoHS3 compliant, matching the original part's environmental compliance status.

Q: Is the impedance difference between the original part (150 mOhms) and substitutes (153 mOhms) significant?

A: No. The 3 mOhm difference represents a 2% variance, which is within acceptable engineering tolerance for aluminum electrolytic capacitors in bypass and decoupling applications. Both parts meet the same ripple current specifications (687.8 mA @ 120 Hz and 917 mA @ 100 kHz).

Q: What is the moisture sensitivity level (MSL) of the substitute parts?

A: Both substitute parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. This matches the original part's MSL specification.

Q: Are there any temperature or lifetime differences between the original and substitute parts?

A: No. All three parts share identical operating temperature range (-55°C to 105°C) and lifetime specification (5000 Hrs @ 105°C).

Q: Which substitute part should be selected for high-volume production?

A: EEV-FK2A221M is recommended for high-volume production due to significantly higher inventory availability (1,000,300 pcs) and Cut Tape & Digi-Reel® packaging compatibility with automated assembly equipment.
