Substitute Part Grouping Explanation

Substitution eligibility for the UPJ2A680MHD6TO is determined by the following critical parameters:

Capacitance: 68 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Case Diameter: 0.492" (12.50mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

All substitute parts listed meet these electrical and mechanical compatibility criteria. Variations in height, ripple current ratings, impedance, and product status are secondary considerations that do not affect basic functional substitution.

Engineering Selection Recommendations

UPM2A680MHD6TO is a direct equivalent from Nichicon's product portfolio. Both the UPJ2A680MHD6TO and UPM2A680MHD6TO share identical electrical specifications and mechanical dimensions. The UPM series includes AEC-Q200 automotive qualification, providing enhanced reliability documentation. Both parts carry Not For New Designs status.

EEU-FC2A680B is an upgrade substitute manufactured by Panasonic Electronic Components. This part maintains all critical electrical and mechanical parameters while offering Active product status, ensuring continued availability and manufacturing support. The EEU-FC2A680B includes AEC-Q200 automotive qualification and is suitable for applications requiring long-term component sourcing. Height variation is 0.020" (0.50mm) less than the main part, which may require PCB layout verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can UPM2A680MHD6TO be used as a direct replacement for UPJ2A680MHD6TO?

A: Yes. Both parts share identical capacitance (68 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), lead spacing (0.197" / 5.00mm), case diameter (0.492" / 12.50mm), and impedance (230 mOhms). Height difference is 0.019" (0.50mm), which does not affect standard through-hole PCB mounting.

Q: Is EEU-FC2A680B compatible with the original UPJ2A680MHD6TO footprint?

A: Yes. The EEU-FC2A680B maintains the same lead spacing (0.197" / 5.00mm), case diameter (0.492" / 12.50mm), and through-hole mounting configuration. Height is 0.020" (0.50mm) shorter, which is within typical PCB clearance tolerances. Verify clearance in your specific layout if height-constrained.

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

A: Both series meet the same electrical specifications for this 68 µF, 100 V rating. The UPM series includes AEC-Q200 automotive qualification. Both are designated Not For New Designs.

Q: Why should I consider EEU-FC2A680B if UPM2A680MHD6TO is available?

A: EEU-FC2A680B carries Active product status, ensuring long-term manufacturing availability and support. Both UPJ and UPM series are Not For New Designs, indicating potential future discontinuation. For applications requiring extended component sourcing windows, the Panasonic EEU-FC2A680B is the recommended long-term solution.

Q: Are all three parts RoHS compliant?

A: Yes. UPJ2A680MHD6TO, UPM2A680MHD6TO, and EEU-FC2A680B are all ROHS3 Compliant.

Q: Do ripple current differences affect substitution?

A: Ripple current ratings are application-dependent. All three parts meet the same 5000 Hrs @ 105°C lifetime specification. If your application requires ripple current handling above 289 mA @ 120 Hz, UPM2A680MHD6TO (380 mA) or EEU-FC2A680B (332.2 mA) provide higher margins. Verify your circuit's actual ripple current requirement before selection.
