Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC2A181 is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 180 µF
• Voltage Rating: 100 V
• Tolerance: ±20%
• Operating Temperature Range: -55°C ~ 105°C
• Polarization: Polar

Mechanical Parameters (Must Match):

• Package Type: Radial, Can
• Mounting Type: Through Hole
• Lead Spacing: 0.295" (7.50mm)
• Case Diameter: 0.630" Dia (16.00mm)

Acceptable Variations:

• Lifetime @ Temperature: Equal to or greater than 5000 Hrs @ 105°C
• Ripple Current ratings: May vary within acceptable operating margins
• Impedance: May vary within acceptable operating margins
• Compliance certifications: AEC-Q200 preferred for automotive applications but not mandatory for general-purpose substitution

The following parts meet these substitution criteria: UPJ2A181MHD6, UPM2A181MHD, and UPW2A181MHD6.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: EEU-FC2A181 The EEU-FC2A181 maintains active production status and carries AEC-Q200 automotive certification. This part is the preferred choice for new designs and applications requiring automotive-grade reliability.

Secondary Selection: UPJ2A181MHD6 The UPJ2A181MHD6 provides direct mechanical and electrical compatibility with identical lead spacing (0.295"), case diameter (0.630"), and impedance (110 mOhms). Height variation is minimal (0.846" vs. 0.866"). This part is suitable for applications where the primary part is unavailable, though it carries "Not For New Designs" status.

Alternative Selection: UPM2A181MHD The UPM2A181MHD maintains AEC-Q200 automotive certification and automotive application rating. However, it features different mechanical dimensions: lead spacing of 0.197" (5.00mm) and case diameter of 0.492" (12.50mm). This part requires PCB layout modification and is not a direct drop-in replacement. Selection is appropriate only when PCB redesign is feasible and automotive compliance is required.

Extended Lifetime Option: UPW2A181MHD6 The UPW2A181MHD6 offers extended lifetime rating of 8000 hours at 105°C compared to the standard 5000 hours. Mechanical dimensions match the primary part (lead spacing 0.295", case diameter 0.630"). This part is suitable for applications requiring extended operational life, though it carries "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can UPJ2A181MHD be used as a direct replacement for EEU-FC2A181? A: No. The UPJ2A181MHD has different mechanical dimensions (lead spacing 0.197" vs. 0.295", case diameter 0.492" vs. 0.630"). It requires PCB layout modification and is not a drop-in replacement.

Q: Which substitute part is a direct drop-in replacement? A: UPJ2A181MHD6 and UPW2A181MHD6 are direct drop-in replacements. Both maintain identical lead spacing (0.295") and case diameter (0.630") as the EEU-FC2A181. Height variations are minimal and typically acceptable within standard PCB clearance tolerances.

Q: What is the significance of "Not For New Designs" status? A: Parts marked "Not For New Designs" are in mature or declining production phases. They remain available for existing designs and legacy applications but should not be selected for new product development. The EEU-FC2A181 (Active status) is the recommended choice for new designs.

Q: Does UPM2A181MHD provide automotive certification? A: Yes. The UPM2A181MHD carries AEC-Q200 automotive certification and is rated for automotive applications. However, its different mechanical dimensions prevent direct substitution without PCB redesign.

Q: What is the difference between UPJ2A181MHD and UPJ2A181MHD6? A: Both parts are from the Nichicon UPJ series with identical electrical specifications. The primary difference is mechanical: UPJ2A181MHD has lead spacing of 0.197" (5.00mm) and case diameter of 0.492" (12.50mm), while UPJ2A181MHD6 has lead spacing of 0.295" (7.50mm) and case diameter of 0.630" (16.00mm). Only UPJ2A181MHD6 is mechanically compatible with EEU-FC2A181.

Q: Can I use UPW2A181MHD6 in place of EEU-FC2A181 for extended reliability? A: Yes. The UPW2A181MHD6 provides 8000-hour lifetime at 105°C versus 5000 hours for the EEU-FC2A181, with identical mechanical dimensions. It is suitable for applications requiring extended operational life, provided that "Not For New Designs" status is acceptable for your application.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (UPJ2A181MHD6, UPM2A181MHD, UPW2A181MHD6) are ROHS3 compliant, matching the compliance status of the EEU-FC2A181.
