AFK157M2AP44T-F Equivalent & Substitute Parts

Part Overview

The AFK157M2AP44T-F is a 150 µF, 100 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in surface mount radial can configuration. This component is rated for automotive applications with AEC-Q200 compliance and is designed for bypass and decoupling functions in high-reliability circuits. The part maintains active product status with 5000-hour lifetime rating at 105°C operating temperature.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and reliability certifications align with the original specification. Substitution becomes necessary due to inventory availability, supply chain considerations, or design flexibility requirements while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the AFK157M2AP44T-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 150 µF (exact match)
• Voltage Rating: 100 V (exact match)
• Tolerance: ±20% (exact match)
• ESR: 170 mOhm @ 100 kHz (exact match)
• Ripple Current @ 120 Hz: 594.8 mA (exact match)
• Ripple Current @ 100 kHz: 793 mA (exact match)
• Lifetime: 5000 Hrs @ 105°C (exact match)
• Operating Temperature: -55°C to 105°C (exact match)

Mechanical Compatibility Requirements:

• Case Diameter: 16.00 mm (exact match)
• Height (Seated Max): 17.00 mm (exact match)
• Mounting Type: Surface Mount (exact match)
• Package Type: Radial, Can - SMD (exact match)

Compliance & Certification Requirements:

• AEC-Q200 Automotive Rating (required)
• RoHS3 Compliance (required)
• MSL Rating: 1 (Unlimited) (required)

The substitute part EEE-FK2A151AM meets all electrical and mechanical equivalence criteria. Surface mount land size variation (17.00 mm × 19.00 mm for AFK157M2AP44T-F versus 17.00 mm × 17.00 mm for EEE-FK2A151AM) does not affect functional substitution as both configurations accommodate standard PCB pad layouts for this case size.

Engineering Selection Recommendations

Primary Selection: AFK157M2AP44T-F

The AFK157M2AP44T-F remains the primary component choice when available. This part carries active product status with established supply inventory (727 pcs in stock) and full compliance with automotive AEC-Q200 qualification and RoHS3 requirements.

Approved Substitute: EEE-FK2A151AM

The Panasonic EEE-FK2A151AM is a direct functional equivalent suitable for substitution in applications currently specified for the AFK157M2AP44T-F. This substitute maintains:

• Identical electrical performance across all rated parameters
• Mechanical compatibility with existing PCB layouts
• Full AEC-Q200 automotive qualification
• RoHS3 compliance
• Active product status with higher inventory availability (1180 pcs in stock)

Both components are suitable for automotive bypass and decoupling applications with equivalent reliability performance over the specified 5000-hour lifetime at 105°C. Selection between these parts is determined by supply availability and procurement requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK2A151AM be used as a direct replacement for AFK157M2AP44T-F in automotive applications?

A: Yes. The EEE-FK2A151AM meets all electrical and mechanical specifications required for direct substitution. Both components carry AEC-Q200 automotive qualification and are rated for identical operating conditions, capacitance, voltage, ESR, and ripple current performance.

Q: Are there differences in surface mount land size between these parts?

A: The AFK157M2AP44T-F specifies a land size of 17.00 mm × 19.00 mm, while the EEE-FK2A151AM specifies 17.00 mm × 17.00 mm. Both configurations are compatible with standard PCB pad layouts for 16 mm diameter radial can SMD packages. The smaller land size of the Panasonic part does not affect functional performance or mechanical stability.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the AFK157M2AP44T-F and EEE-FK2A151AM carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the basis for substitution eligibility?

A: Substitution is based on exact equivalence of capacitance (150 µF), voltage rating (100 V), tolerance (±20%), ESR (170 mOhm @ 100 kHz), ripple current specifications, operating temperature range (-55°C to 105°C), lifetime rating (5000 Hrs @ 105°C), mechanical dimensions, and compliance certifications (AEC-Q200, RoHS3).

Q: Are there any applications where one part is preferred over the other?

A: Both parts are suitable for bypass and decoupling applications in automotive circuits. Selection is based on supply chain availability and procurement lead times rather than application-specific performance differences.

Q: What compliance certifications apply to both substitute parts?

A: Both the AFK157M2AP44T-F and EEE-FK2A151AM carry AEC-Q200 automotive qualification, RoHS3 compliance, and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8532.22.0020.
