Substitute Part Grouping Explanation

Substitution of the UPS1J331MHD is determined by strict electrical and mechanical compatibility:

Electrical Compatibility Requirements:

Capacitance: 330 µF (exact match required)
Voltage Rating: 63 V (minimum; higher ratings acceptable)
Tolerance: ±20% (matching tolerance class)
Polarization: Polar (must match)
Operating Temperature: -55°C to 105°C (minimum range required)

Mechanical Compatibility Requirements:

Package Type: Radial, Can (must match)
Mounting Type: Through Hole (must match)
Lead Spacing: 0.197" (5.00 mm) preferred for direct PCB fit
Case Diameter: 0.492" (12.50 mm) preferred for space constraints
Height: Component height must not exceed available board clearance

Acceptable Variations:

Lifetime rating may exceed 3000 Hrs @ 105°C
Ripple current capability may exceed minimum requirements
Impedance may be lower (improved performance)
Product status may be Active (preferred for new inventory)
Compliance certifications (AEC-Q200, ROHS3) may be present

Substitutes are grouped by lead spacing and case dimensions, as these determine PCB compatibility. Parts with identical lead spacing (5.00 mm) and case diameter (12.50 mm) are direct mechanical replacements. Parts with different lead spacing (7.50 mm) or case diameter (18.00 mm) require PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can UPJ1J331MHD directly replace UPS1J331MHD on the same PCB?

A: UPJ1J331MHD shares identical lead spacing (5.00 mm) and case diameter (12.50 mm), enabling direct PCB footprint compatibility. However, the height increases from 0.866" to 1.043", requiring verification that available board clearance accommodates the taller component.

Q: What is the difference between Nichicon UPS, UPJ, UPM, and UPW series?

A: These series differ in lifetime rating at 105°C: UPS provides 3000 Hrs, UPJ and UPM provide 5000 Hrs, and UPW provides 7000 Hrs. UPM series includes AEC-Q200 automotive qualification. All maintain identical electrical specifications (330 µF, 63 V, ±20%).

Q: Are MAL215058331E3 and MAL215068331E3 interchangeable?

A: Yes. Both Vishay parts share identical electrical specifications (330 µF, 63 V, ±20%, 7000 Hrs @ 105°C), mechanical dimensions (5.00 mm lead spacing, 12.50 mm diameter, 0.866" height), and compliance certifications (ROHS3, AEC-Q200). They are functionally equivalent.

Q: Which substitute offers the best long-term reliability?

A: UPW1J331MHD, MAL215058331E3, and MAL215068331E3 provide 7000 Hrs @ 105°C lifetime, the highest among available substitutes. For automotive applications, MAL215058331E3 and MAL215068331E3 add AEC-Q200 certification.

Q: Can EEU-FC1J331L be used as a drop-in replacement?

A: No. EEU-FC1J331L has a reduced case diameter (0.394" vs. 0.492") and increased height (1.181" vs. 0.866"), requiring PCB layout modification. It is suitable only for applications where space constraints permit the compact form factor.

Q: What is the difference between EEU-FC1J331 and EEU-FC1J331B?

A: Both are Panasonic FC series with identical electrical and mechanical specifications. The primary difference is packaging: EEU-FC1J331 is supplied in Bulk, while EEU-FC1J331B is supplied in Cut Tape (CT). Component performance is equivalent.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions.

Q: Which substitute has the lowest impedance?

A: UPM1J331MHD provides 49 mOhms impedance, the lowest among substitutes with 5.00 mm lead spacing and 12.50 mm diameter. This offers superior high-frequency performance compared to the original UPS1J331MHD at 120 mOhms.
