Substitute Part Grouping Explanation

Substitution for the UPS2F330MHD is determined by the following critical parameters:

Capacitance Value: 33 µF (exact match required)
Voltage Rating: 315 V minimum (equal or higher voltage rating is acceptable)
Tolerance: ±20% (standard tolerance for general purpose applications)
Polarization: Polar (electrolytic capacitor type)
Mounting Type: Through Hole (radial lead configuration)
Physical Dimensions: Lead spacing 0.295" (7.50 mm), case diameter 0.630" (16.00 mm), height compatibility within PCB layout constraints
Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts listed maintain the same capacitance, tolerance, polarization, and mounting configuration. Variations in voltage rating, lifetime rating, and physical height are noted where they differ from the original specification.

Engineering Selection Recommendations

Direct Substitutes (Same Electrical Characteristics)

UPS2F330MHD1TN and UPW2F330MHD1TN are direct electrical equivalents with identical capacitance, voltage rating, and tolerance. Both are Nichicon products with the same lead spacing and case dimensions. UPS2F330MHD1TN differs only in packaging (Cut Tape vs. bulk) and product status (Not For New Designs). UPW2F330MHD1TN offers extended lifetime (8000 Hrs vs. 3000 Hrs @ 105°C) while maintaining the same electrical specifications and physical footprint.

Manufacturer-Recommended Upgrade

UCS2G330MHD is an active product from Nichicon with superior specifications: 400 V voltage rating (exceeds 315 V requirement), 10000 Hrs lifetime @ 105°C, and higher ripple current ratings. Physical height is reduced to 0.846" (21.50 mm), which may provide PCB layout advantages. This part is suitable for direct replacement where voltage headroom and extended operational life are beneficial.

Cross-Manufacturer Alternative

EKXF451ELL330ML25S is manufactured by Chemi-Con (KXF series) and represents the highest performance option: 450 V voltage rating, 20000 Hrs lifetime @ 105°C, and superior ripple current handling. Physical dimensions are compatible with the original specification. This part is active and ROHS3 compliant, suitable for applications requiring extended service life and enhanced reliability margins.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original UPS2F330MHD.

Frequently Asked Questions (FAQ)

Q: Can UCS2G330MHD replace UPS2F330MHD directly?

A: Yes. UCS2G330MHD is electrically compatible as a direct replacement. It maintains the same 33 µF capacitance, ±20% tolerance, and through-hole radial configuration. The 400 V rating exceeds the 315 V requirement, providing additional voltage margin. Physical height is 0.846" (21.50 mm) versus 1.063" (27.00 mm) for the original, which may affect PCB layout if height clearance is constrained.

Q: What is the difference between UPS2F330MHD1TN and UPW2F330MHD1TN?

A: Both are Nichicon products with identical electrical specifications (33 µF, 315 V, ±20%). The primary difference is lifetime rating: UPS2F330MHD1TN is rated 3000 Hrs @ 105°C, while UPW2F330MHD1TN is rated 8000 Hrs @ 105°C. Both use Cut Tape packaging and have "Not For New Designs" status. Physical dimensions and lead spacing are identical.

Q: Is EKXF451ELL330ML25S compatible with the original circuit?

A: Yes. EKXF451ELL330ML25S maintains the same 33 µF capacitance, ±20% tolerance, and through-hole radial lead configuration. The 450 V rating and 20000 Hrs lifetime provide enhanced performance margins. Lead spacing (0.295" / 7.50 mm) and case diameter (0.630" / 16.00 mm) are identical. Height is 1.043" (26.50 mm), slightly less than the original 1.063" (27.00 mm).

Q: Why is the original UPS2F330MHD marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Nichicon. Equivalent alternatives with the same or superior specifications are available from the same manufacturer (UCS2G330MHD) or cross-manufacturer sources (EKXF451ELL330ML25S from Chemi-Con).

Q: What packaging options are available for substitutes?

A: UPS2F330MHD1TN and UPW2F330MHD1TN are supplied in Cut Tape (CT) packaging. UCS2G330MHD and EKXF451ELL330ML25S are supplied in Bulk packaging. Packaging selection depends on procurement volume and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (UPS2F330MHD1TN, UCS2G330MHD, UPW2F330MHD1TN, and EKXF451ELL330ML25S) are ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with the original specification.
