Substitute Part Grouping Explanation

Substitution eligibility for the UPJ2A331MHD6TN is determined by strict alignment of the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can with identical lead spacing (0.295" / 7.50 mm) and case dimensions (0.709" Dia / 18.00 mm, 1.063" height max)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute parts identified—UPM2A331MHD6TN (Nichicon) and EEU-FC2A331SB (Panasonic Electronic Components)—meet all these criteria and are therefore electrically and mechanically interchangeable with the main part.

Engineering Selection Recommendations

UPM2A331MHD6TN (Nichicon): This part is a parametric equivalent offering identical electrical and mechanical specifications to the UPJ2A331MHD6TN. However, it carries the same "Not For New Designs" status. Selection of this substitute is appropriate for direct replacement in existing production lines where component continuity is required. The UPM2A331MHD6TN includes AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components.

EEU-FC2A331SB (Panasonic Electronic Components): This part is classified as an upgrade option due to its "Active" product status, making it the preferred choice for new designs and long-term production planning. The EEU-FC2A331SB meets all electrical and mechanical compatibility requirements and carries AEC-Q200 automotive qualification. Its active status ensures continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can UPM2A331MHD6TN be used as a direct replacement for UPJ2A331MHD6TN?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and physical dimensions (0.709" diameter, 1.063" height, 0.295" lead spacing). They are electrically and mechanically interchangeable.

Q: What is the difference between the parametric equivalent and the upgrade option?

A: The UPM2A331MHD6TN is a parametric equivalent with matching specifications but carries "Not For New Designs" status. The EEU-FC2A331SB is an upgrade with "Active" product status, ensuring long-term availability and manufacturer support. Both are functionally equivalent; the upgrade is recommended for new designs.

Q: Are there any differences in ripple current ratings?

A: Yes. The UPJ2A331MHD6TN specifies 1.08 A @ 120 Hz and 1.42 A @ 10 kHz. The UPM2A331MHD6TN provides 1.26 A @ 120 Hz and 1.65 A @ 10 kHz. The EEU-FC2A331SB specifies 923 mA @ 120 Hz and 1.42 A @ 100 kHz. All three parts meet the same 5000-hour lifetime specification at 105°C and share identical impedance (70 mOhms). Application-specific ripple current requirements should be evaluated against these values.

Q: Do all three parts have the same RoHS compliance?

A: Yes. All three parts are ROHS3 Compliant, meeting the same environmental regulatory requirements.

Q: Which part should be selected for new product designs?

A: The EEU-FC2A331SB (Panasonic) is the recommended choice for new designs due to its "Active" product status. This ensures continued manufacturer support, availability, and compliance with long-term supply chain requirements.
