Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC1J181 is determined by the following criteria:

Mandatory Parameters (Must Match):

• Capacitance: 180 µF
• Voltage - Rated: 63 V
• Tolerance: ±20%
• Polarization: Polar
• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Operating Temperature Range: -55°C ~ 105°C

Flexible Parameters (May Vary):

• Lifetime @ Temperature (3000 Hrs minimum acceptable)
• Physical dimensions (diameter and height)
• Ripple current ratings
• Impedance
• Manufacturer and series designation
• Packaging format (Bulk or Cut Tape)
• Product status (Active or Not For New Designs)

All substitute parts listed maintain identical electrical specifications (capacitance, voltage, tolerance) and mechanical compatibility (lead spacing, mounting type, package style) with the main part.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications: EEU-FC1J181S and EEU-FC1J181SB are direct Panasonic alternatives with Active product status. Both maintain full electrical compatibility and offer extended 5000-hour lifetime at 105°C. EEU-FC1J181S is supplied in Bulk packaging, while EEU-FC1J181SB is supplied in Cut Tape format for automated assembly. Physical dimensions differ slightly; verify PCB layout clearance before substitution.

For Automotive AEC-Q200 Applications: The main part EEU-FC1J181 carries AEC-Q200 certification. Among substitutes, only UPM1J181MPD maintains AEC-Q200 rating; however, this part is marked Not For New Designs. EEU-FC1J181S and EEU-FC1J181SB retain AEC-Q200 certification and are recommended for automotive applications requiring active product status.

For Extended Lifetime Requirements: UPW1J181MHD6 provides 7000-hour lifetime at 105°C, the highest among all listed substitutes. This part is marked Not For New Designs. For new designs requiring extended lifetime with active status, EEU-FC1J181S offers 5000-hour lifetime.

For Dimensional Constraints: UPW1J181MPD, UPJ1J181MPD, and UPM1J181MPD maintain the original 10.00mm diameter but vary in height. UPJ1J181MPD and UPM1J181MPD are significantly taller (33.00mm and 34.60mm respectively) and require PCB layout verification. UPW1J181MPD matches original dimensions exactly but is Not For New Designs.

For Low Impedance Applications: UPM1J181MPD offers the lowest impedance at 75 mOhms, followed by UPJ1J181MPD at 110 mOhms. Both are Nichicon parts marked Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute EEU-FC1J181 with EEU-FC1J181S directly on the PCB? A: Electrical substitution is valid; both parts share identical capacitance, voltage, tolerance, and lead spacing. However, EEU-FC1J181S has different physical dimensions (0.492" diameter vs. 0.394", and 0.630" height vs. 0.787"). Verify PCB layout clearance and mounting hole spacing before substitution.

Q: What is the difference between EEU-FC1J181S and EEU-FC1J181SB? A: Both parts are electrically and mechanically identical with 180 µF, 63 V, 5000-hour lifetime specifications. The difference is packaging format: EEU-FC1J181S is supplied in Bulk, while EEU-FC1J181SB is supplied in Cut Tape (CT) for automated pick-and-place assembly.

Q: Are Nichicon UPW, UPJ, and UPM series parts suitable for new designs? A: All Nichicon substitutes listed (UPW1J181MPD, UPJ1J181MPD, UPM1J181MPD, UPW1J181MHD6) are marked Not For New Designs. For new product development, use Panasonic EEU-FC1J181S or EEU-FC1J181SB, which carry Active product status.

Q: Which substitute offers the best performance for automotive applications? A: EEU-FC1J181S maintains Active product status and AEC-Q200 automotive certification with 5000-hour lifetime. This is the recommended substitute for automotive applications requiring current product support.

Q: Can I use UPM1J181MPD as a substitute in automotive designs? A: UPM1J181MPD carries AEC-Q200 certification and is suitable for automotive applications electrically and mechanically. However, it is marked Not For New Designs, limiting its use to legacy or replacement applications only.

Q: What is the impact of different impedance values among substitutes? A: Impedance differences (ranging from 75 mOhms to 150 mOhms) affect ripple current handling and high-frequency performance. Lower impedance parts (UPM1J181MPD at 75 mOhms) provide better performance in high-ripple-current applications. Verify application ripple current requirements before selecting based on impedance.

Q: Are all listed substitutes RoHS3 compliant? A: Yes, all substitute parts listed are ROHS3 compliant. UPM1J181MPD is marked REACH Affected; verify REACH compliance requirements for your specific application and region.

Q: What is the lead spacing requirement, and do all substitutes match? A: Lead spacing is 0.197" (5.00mm) for all parts listed. This parameter is fixed and identical across the main part and all substitutes, ensuring PCB footprint compatibility.
