Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (AFK157M35F24VT-F)

The AFK157M35F24VT-F from Cornell Dubilier Electronics is a direct equivalent variant of the primary part. It maintains identical electrical specifications (150 µF, 35 V, ±20%, 160 mOhm ESR, 2000 Hrs @ 105°C) with AEC-Q200 compliance. The primary difference is reduced height (10.00 mm vs. 10.50 mm) and modified land size (8.30 x 8.30 mm vs. 8.30 x 10.00 mm). This variant is suitable for space-constrained PCB layouts while preserving all electrical performance characteristics.

Enhanced Performance Options (Lower ESR)

The 35TKV150M8X10.5 (Rubycon) and EEE-FP1V151AP (Panasonic) offer reduced ESR of 80 mOhm at 100 kHz compared to the primary part's 160 mOhm. Both maintain AEC-Q200 compliance and 2000-hour lifetime at 105°C. These options provide higher ripple current capacity (850 mA @ 100 kHz vs. 600 mA) and are suitable for applications requiring lower impedance performance. Physical dimensions remain compatible within specified tolerances.

Panasonic FK Series (Standard Performance)

The EEE-FK1V151AP and EEE-FK1V151P maintain identical electrical specifications to the primary part (160 mOhm ESR, 600 mA ripple current @ 100 kHz) with AEC-Q200 compliance. The primary distinction is packaging format: EEE-FK1V151AP is supplied in Tape & Reel, while EEE-FK1V151P is supplied in Cut Tape & Digi-Reel format. Both are suitable for direct substitution in automotive applications.

Panasonic FN Series (Halogen-Free Upgrade)

The EEE-FN1V151L and EEE-FN1V151P are halogen-free variants from Panasonic's FN series. Both maintain 160 mOhm ESR, 600 mA ripple current @ 100 kHz, and AEC-Q200 compliance. These parts are designated as upgrade options and are suitable for applications with halogen-free material requirements while preserving all electrical performance characteristics of the primary part.

Nichicon UCL Series (General Purpose Alternative)

The UCL1V151MNL1GS from Nichicon provides 80 mOhm ESR and 850 mA ripple current @ 100 kHz with 2000-hour lifetime at 105°C. This part does not carry AEC-Q200 certification and is rated for general purpose applications rather than automotive. Selection of this part requires confirmation that automotive qualification is not a design requirement.

Compliance and Certification Summary

All recommended substitutes maintain RoHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and ECCN EAR99 classification. AEC-Q200 certification is present in all parts except UCL1V151MNL1GS. Selection should prioritize AEC-Q200 rated parts for automotive applications unless design specifications explicitly permit general-purpose alternatives.

Frequently Asked Questions (FAQ)

Q: Can AFK157M35F24VT-F be used as a direct replacement for AFK157M35F24T-F?

A: Yes. The AFK157M35F24VT-F is a direct electrical equivalent with identical capacitance (150 µF), voltage rating (35 V), tolerance (±20%), ESR (160 mOhm @ 100 kHz), and lifetime (2000 Hrs @ 105°C). The primary differences are reduced height (10.00 mm vs. 10.50 mm) and modified land size (8.30 x 8.30 mm vs. 8.30 x 10.00 mm). PCB layout verification is required to confirm compatibility with the modified footprint dimensions.

Q: What is the difference between 160 mOhm and 80 mOhm ESR options?

A: ESR (Equivalent Series Resistance) directly affects impedance and ripple current handling. The 80 mOhm options (35TKV150M8X10.5, EEE-FP1V151AP, UCL1V151MNL1GS) provide lower impedance and higher ripple current capacity (850 mA @ 100 kHz) compared to 160 mOhm options (600 mA @ 100 kHz). Lower ESR reduces heat generation and voltage ripple in high-frequency applications. Selection depends on circuit requirements for ripple current and thermal performance.

Q: Are all substitute parts AEC-Q200 compliant?

A: No. The UCL1V151MNL1GS from Nichicon does not carry AEC-Q200 certification and is rated for general purpose applications. All other substitutes (Cornell Dubilier AFK series, Rubycon TKV series, and Panasonic FK and FN series) maintain AEC-Q200 compliance. For automotive applications, AEC-Q200 certification is required; therefore, the Nichicon part is not suitable unless design specifications explicitly permit non-automotive-qualified components.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel packaging supplies components on cut tape segments, suitable for lower-volume or mixed-component assembly. Both formats contain identical components; the difference is in supply format and handling. Selection depends on assembly equipment compatibility and order volume requirements.

Q: Can the Panasonic FN series (halogen-free) be used in place of standard FK series?

A: Yes. The EEE-FN1V151L and EEE-FN1V151P maintain identical electrical specifications to the FK series (160 mOhm ESR, 600 mA ripple current @ 100 kHz, 2000 Hrs @ 105°C) with AEC-Q200 compliance. The FN series is designated as a halogen-free upgrade option. Selection of FN series is appropriate when halogen-free material requirements are specified in design documentation.

Q: What are the physical dimension constraints for PCB layout compatibility?

A: The primary part AFK157M35F24T-F has a maximum seated height of 10.50 mm and land size of 8.30 x 10.00 mm. Substitute parts vary within these ranges: height from 10.00 to 10.50 mm and land size from 8.30 x 8.30 mm to 8.30 x 10.00 mm. All variations are within the radial can SMD package specification. PCB layout must accommodate the specific footprint of the selected part; reduced height variants (10.00 mm) may provide additional clearance in space-constrained designs.

Q: Is the Rubycon 35TKV150M8X10.5 suitable for automotive applications?

A: Yes. The 35TKV150M8X10.5 carries AEC-Q200 compliance and is rated for automotive applications. It provides enhanced performance with 80 mOhm ESR and 850 mA ripple current @ 100 kHz compared to the primary part's 160 mOhm and 600 mA. All other electrical specifications (150 µF, 35 V, ±20%, 2000 Hrs @ 105°C, -55°C to 105°C operating range) are maintained.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: AFK157M35F24VT-F (1541 pcs), 35TKV150M8X10.5 (1560 pcs), EEE-FK1V151AP (1977 pcs), EEE-FK1V151P (2160 pcs), EEE-FP1V151AP (3576 pcs), UCL1V151MNL1GS (6311 pcs), EEE-FN1V151L (2409 pcs), and EEE-FN1V151P (3481 pcs). Inventory levels are subject to change; current availability should be verified at time of procurement.

Q: Can UCL1V151MNL1GS be used in automotive designs?

A: The UCL1V151MNL1GS does not carry AEC-Q200 certification and is rated for general purpose applications. Use in automotive designs requires explicit design approval and documentation confirming that automotive qualification is not a mandatory requirement. If AEC-Q200 compliance is specified, this part is not suitable.
