EEU-FC2A151S Equivalent & Substitute Parts

Part Overview

The EEU-FC2A151S is a 150 µF, 100 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 5000 hours at 105°C and carries AEC-Q200 automotive qualification. The part is currently in active production status with 933 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate alternative manufacturers for supply chain resilience, or when specific performance characteristics of substitute series better match application demands.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC2A151S is determined by the following core parameters:

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

Substitute parts are grouped into two categories based on lifetime rating and manufacturer:

Category A: 5000 Hrs @ 105°C (Direct Equivalents)

• EEU-FC2A151 (Panasonic, same series, different lead spacing and dimensions)
• UPJ2A151MHD6 (Nichicon UPJ series, matching impedance and ripple current specifications)
• UPM2A151MHD6 (Nichicon UPM series, AEC-Q200 rated, automotive qualified)

Category B: Alternative Lifetime Ratings

• UPJ2A151MHD (Nichicon UPJ series, 5000 Hrs @ 105°C, general purpose rated)
• UPM2A151MHD (Nichicon UPM series, 5000 Hrs @ 105°C, AEC-Q200 rated)
• UPS2A151MHD (Nichicon UPS series, 3000 Hrs @ 105°C, reduced lifetime)
• UPW2A151MHD (Nichicon UPW series, 7000 Hrs @ 105°C, extended lifetime)

Parameter Comparison

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): EEU-FC2A151 (Panasonic FC series, active production) is the primary substitute when the EEU-FC2A151S is unavailable. Both parts carry AEC-Q200 qualification and maintain identical electrical specifications. The dimensional difference (lead spacing 5.00mm vs. 7.50mm, height 25.00mm vs. 15.00mm) requires PCB layout verification.

UPM2A151MHD6 (Nichicon UPM series) is an alternative for automotive applications with AEC-Q200 qualification, though marked "Not For New Designs." This part matches the lead spacing and diameter of the primary part but has a slightly different height (17.00mm vs. 15.00mm).

For General Purpose Applications: UPJ2A151MHD6 (Nichicon UPJ series) provides equivalent electrical performance with matching lead spacing and diameter to the primary part. Height difference (16.50mm vs. 15.00mm) is minimal. This part is marked "Not For New Designs."

UPW2A151MHD (Nichicon UPW series) offers extended lifetime (7000 Hrs @ 105°C) for applications requiring higher reliability margins, though it has different lead spacing (5.00mm) and dimensions.

Not Recommended: UPS2A151MHD has reduced lifetime (3000 Hrs @ 105°C) and higher impedance (130 mOhms), making it unsuitable as a direct substitute for the 5000-hour rated primary part.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-FC2A151 as a direct replacement for EEU-FC2A151S?

A: Electrically, yes. Both are Panasonic FC series capacitors with identical capacitance (150 µF), voltage (100 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), and AEC-Q200 qualification. However, the lead spacing differs (5.00mm vs. 7.50mm) and the height differs (25.00mm vs. 15.00mm). PCB layout must be verified before substitution.

Q: What is the difference between UPJ and UPM series from Nichicon?

A: Both series meet the core electrical specifications (150 µF, 100 V, 5000 Hrs @ 105°C). The UPM series carries AEC-Q200 automotive qualification, while the UPJ series does not. Both are marked "Not For New Designs." The UPM series is preferred for automotive applications.

Q: Why is UPS2A151MHD listed as a substitute if it has only 3000 Hrs lifetime?

A: UPS2A151MHD meets all core electrical parameters (capacitance, voltage, tolerance, polarization, package type, operating temperature range). However, the reduced lifetime rating (3000 Hrs vs. 5000 Hrs @ 105°C) and higher impedance (130 mOhms vs. 120 mOhms) make it unsuitable for applications requiring the full 5000-hour specification. Use only if application lifetime requirements are lower.

Q: Can I use UPW2A151MHD for extended reliability?

A: UPW2A151MHD provides 7000 Hrs @ 105°C lifetime, exceeding the primary part specification. All core electrical parameters match. However, lead spacing is 5.00mm (vs. 7.50mm on the primary part) and height is 25.00mm (vs. 15.00mm). PCB layout compatibility must be confirmed.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the primary part.

Q: What is the impact of different impedance values?

A: Impedance differences (110-130 mOhms across the substitute range vs. 120 mOhms on the primary part) affect ripple current handling and high-frequency performance. For applications with strict ripple current or noise specifications, impedance matching should be verified against circuit requirements.
