EEU-FC2A151SB Equivalent & Substitute Parts

Part Overview

The EEU-FC2A151SB is a 150 µF, 100 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FC series. This radial, through-hole component is rated for 5000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The part is currently active and available in Tape & Box packaging with 773 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, when packaging requirements differ, or when design flexibility allows for alternative manufacturers while maintaining electrical and mechanical compatibility within specified tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance: 150 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 100 V (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Footprint): Parts with matching lead spacing (0.295" / 7.50mm), size (0.709" Dia / 18.00mm), and height specifications. These parts are pin-compatible and require no PCB layout modifications.

Compatible Substitutes (Different Footprint): Parts with different lead spacing (0.197" / 5.00mm), size (0.492" Dia / 12.50mm), or height specifications. These parts meet all electrical parameters but require PCB layout verification before implementation.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (No PCB Modification Required):

EEU-FC2A151S is the primary direct substitute. It maintains identical lead spacing (0.295" / 7.50mm), diameter (0.709" / 18.00mm), and electrical specifications as the EEU-FC2A151SB. Both parts are manufactured by Panasonic, carry Active product status, and meet AEC-Q200 automotive qualification. The only difference is packaging format (Bulk vs. Tape & Box) and a minor height reduction (0.591" vs. 0.650"), which does not affect electrical performance or mechanical compatibility.

UPJ2A151MHD6 and UPM2A151MHD6 are footprint-compatible alternatives from Nichicon. Both maintain the 0.295" lead spacing and 0.709" diameter. However, both carry "Not For New Designs" product status. UPM2A151MHD6 retains AEC-Q200 automotive qualification, while UPJ2A151MHD6 does not.

For Applications Allowing PCB Layout Modification:

EEU-FC2A151 (Panasonic, Active status, AEC-Q200) is electrically equivalent but requires PCB layout changes due to different footprint (0.197" lead spacing, 0.492" diameter, 0.984" height).

Nichicon alternatives with different footprints include UPJ2A151MHD, UPM2A151MHD, UPS2A151MHD, and UPW2A151MHD. All require PCB layout verification. UPS2A151MHD has reduced lifetime (3000 Hrs vs. 5000 Hrs @ 105°C) and should not be selected for applications requiring 5000-hour minimum lifetime. UPW2A151MHD offers extended lifetime (7000 Hrs @ 105°C) but carries "Not For New Designs" status.

Compliance Considerations:

All listed parts are ROHS3 compliant. UPM2A151MHD and UPM2A151MHD6 are REACH Affected; all others are REACH Unaffected. For automotive applications, prioritize parts with AEC-Q200 ratings: EEU-FC2A151SB, EEU-FC2A151S, EEU-FC2A151, UPM2A151MHD, and UPM2A151MHD6.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A151S be used as a direct replacement for EEU-FC2A151SB?

A: Yes. Both parts are manufactured by Panasonic with identical electrical specifications (150 µF, 100 V, ±20%, 5000 Hrs @ 105°C), matching lead spacing (0.295" / 7.50mm), and identical diameter (0.709" / 18.00mm). The height difference (0.591" vs. 0.650") does not affect compatibility. The only difference is packaging format.

Q: What is the difference between parts with 0.295" and 0.197" lead spacing?

A: Lead spacing determines PCB hole pattern and component placement. Parts with 0.295" (7.50mm) spacing have wider pin separation than parts with 0.197" (5.00mm) spacing. These are not interchangeable without PCB redesign. Verify your PCB layout before selecting a substitute with different lead spacing.

Q: Why do some substitutes have "Not For New Designs" status?

A: This designation indicates the manufacturer has discontinued the part for new applications. While existing inventory may be available, these parts are not recommended for new product development. Panasonic FC and EEU-FC series parts with Active status are preferred for new designs.

Q: Can UPS2A151MHD replace EEU-FC2A151SB?

A: UPS2A151MHD is not recommended as a substitute. While it matches capacitance, voltage, and tolerance, it has reduced lifetime (3000 Hrs vs. 5000 Hrs @ 105°C), different lead spacing (0.197" vs. 0.295"), and lacks AEC-Q200 automotive qualification. Use only if application requirements allow reduced lifetime and PCB layout modification is feasible.

Q: Are Nichicon UPM series parts suitable for automotive applications?

A: UPM2A151MHD and UPM2A151MHD6 carry AEC-Q200 automotive qualification and are suitable for automotive applications. However, both have "Not For New Designs" status. For new automotive designs, use Panasonic EEU-FC series parts or evaluate alternative current-production automotive-qualified capacitors.

Q: What is the impact of impedance differences between substitutes?

A: Impedance values (110–130 mOhms) are provided for reference. All listed parts fall within acceptable ranges for this capacitance and voltage class. Impedance differences do not prevent substitution but may affect ripple current handling characteristics in high-frequency applications. Verify ripple current requirements against the specific substitute part's datasheet.

Q: Can height differences affect PCB assembly?

A: Yes. Height variations (0.591" to 1.063") may affect component clearance, solder reflow profiles, and automated assembly processes. Verify height compatibility with your PCB design, enclosure constraints, and assembly equipment before selecting a substitute with different height specifications.
