Key Parameters

Substitute Part Grouping Explanation

Substitution for the UPJ2A101MPD is determined by strict equivalence in the following parameters:

• Capacitance: 100 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 / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required for PCB compatibility)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required for mechanical fit)
• Height - Seated (Max): 1.299" (33.00mm) (maximum allowable height for board clearance)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

Lifetime at temperature and ripple current ratings may vary among substitutes without affecting basic functionality, provided the application does not impose specific thermal or ripple current demands beyond the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Mechanical and Electrical Substitutes (Preferred):

UPM2A101MPD and EEU-FC2A101L are the closest substitutes to UPJ2A101MPD. Both maintain identical lead spacing (0.197" / 5.00mm), identical size diameter (0.394" / 10.00mm), and identical impedance (150 mOhms). UPM2A101MPD is a Nichicon product with matching lifetime rating (5000 Hrs @ 105°C). EEU-FC2A101L is a Panasonic product with Active product status, offering long-term availability and supply chain stability.

Secondary Substitutes (Mechanical Constraints):

UPS2A101MHD and UPW2A101MHD maintain lead spacing compatibility but feature larger diameter (0.492" / 12.50mm) and reduced height. These are suitable only if PCB layout permits the increased footprint. UPW2A101MHD offers extended lifetime (7000 Hrs @ 105°C), beneficial for high-reliability applications.

Not Recommended for Direct Substitution:

UPM2A101MHD6 has incompatible lead spacing (0.295" / 7.50mm) and larger diameter (0.630" / 16.00mm), requiring PCB redesign.

Product Status Consideration:

All Nichicon substitutes carry "Not For New Designs" status. EEU-FC2A101 and EEU-FC2A101L from Panasonic carry Active status, indicating continued manufacturing and supply availability for long-term applications.

Frequently Asked Questions (FAQ)

Q: Can UPM2A101MPD replace UPJ2A101MPD directly on the PCB?

A: Yes. UPM2A101MPD matches all critical mechanical parameters: lead spacing (0.197" / 5.00mm), size diameter (0.394" / 10.00mm), and height (1.319" / 34.60mm, within tolerance of the original 1.299"). Electrical parameters are identical. The height difference of 0.020" (0.50mm) is within typical PCB clearance margins.

Q: What is the difference between UPS2A101MHD and UPW2A101MHD?

A: Both parts share identical electrical specifications (100 µF, 100 V, ±20%) and lead spacing (0.197" / 5.00mm). The primary differences are lifetime rating (UPS2A101MHD: 3000 Hrs @ 105°C; UPW2A101MHD: 7000 Hrs @ 105°C) and physical dimensions. UPW2A101MHD is taller (0.787" / 20.00mm) but offers superior thermal endurance. UPS2A101MHD is more compact (0.866" / 22.00mm height).

Q: Why does EEU-FC2A101L have a different height than EEU-FC2A101?

A: EEU-FC2A101L is a variant with reduced lifetime rating (3000 Hrs @ 105°C versus 5000 Hrs for EEU-FC2A101), resulting in a more compact design (1.181" / 30.00mm height). Both maintain identical lead spacing and diameter, making them mechanically interchangeable in most applications where the reduced lifetime is acceptable.

Q: Can I use a substitute with different lead spacing?

A: No. Lead spacing determines PCB hole positioning. UPM2A101MHD6 with 0.295" (7.50mm) spacing cannot be installed in a PCB designed for 0.197" (5.00mm) spacing without drilling new holes and removing original traces, effectively requiring PCB redesign.

Q: Is EEU-FC2A101 a better choice than Nichicon substitutes?

A: EEU-FC2A101 and EEU-FC2A101L carry Active product status from Panasonic, ensuring continued availability and supply chain stability. However, mechanical compatibility must be verified: EEU-FC2A101 has larger diameter (0.492" / 12.50mm) and reduced height (0.787" / 20.00mm) compared to UPJ2A101MPD. EEU-FC2A101L is mechanically closer to the original, with matching diameter and comparable height.

Q: What does "Not For New Designs" mean for substitution?

A: This designation indicates the product is in mature or end-of-life phase. For legacy system repair and maintenance, these parts remain valid. For new product development, Active-status alternatives such as EEU-FC2A101 or EEU-FC2A101L are preferred to ensure long-term supply availability.
