Substitute Part Grouping Explanation

Substitution eligibility for the UVK1J331MPD1TD is determined by strict equivalence across the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in ripple current ratings, lifetime specifications at different temperatures, and operating temperature ranges are noted but do not disqualify substitution when the primary parameters align.

Engineering Selection Recommendations

Nichicon Series (UFW1J331MPD1TD, UKW1J331MPD1TD, UVR1J331MPD1TD): These parts maintain identical electrical and mechanical specifications to the UVK1J331MPD1TD. All are ROHS3 compliant and REACH unaffected. UFW1J331MPD1TD offers the highest inventory availability at 10763 pieces. All three Nichicon alternatives carry Not For New Designs status, consistent with the original part.

Würth Elektronik 860010775019: This part is Active status and ROHS3 compliant. Height is 0.846" (21.50 mm) versus 0.866" (22.00 mm) on the original, a 0.02" reduction that may affect board layout in space-constrained applications. Ripple current at 100 kHz is 1.04742 A, comparable to the original specification.

Chemi-Con ESMG630ETD331MJ20S: This part is Active status and ROHS3 compliant. Packaging is Tape & Box (TB) rather than Cut Tape (CT). Height is 0.846" (21.50 mm). Ripple current at 100 kHz is 1.065 A, matching the original high-frequency specification.

Panasonic ECA-1JHG331B: This part is Active status with extended operating temperature range (-55°C ~ 105°C) and higher lifetime rating (2000 Hrs @ 105°C). ROHS3 compliant. Height matches the original at 0.866" (22.00 mm). Ripple current specifications are lower than the original.

Panasonic ECA-1JM331B: This part is Active status and ROHS3 compliant. Operating temperature and lifetime match the original specification. Height is 0.866" (22.00 mm). Ripple current at 10 kHz is 935 mA versus 975 mA on comparable Nichicon alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute UVK1J331MPD1TD with any of these parts directly?

A: Yes, all listed parts meet the core electrical and mechanical parameters: 330 µF capacitance, 63 V voltage rating, ±20% tolerance, 0.197" lead spacing, 0.394" package diameter, and through-hole mounting. Physical height varies slightly on some alternatives; verify board layout clearance before installation.

Q: What is the difference between Nichicon UFW, UKW, and UVR series?

A: All three series share identical electrical specifications and operating parameters with the original UVK series. Differences are internal to the manufacturer's product line organization. Selection can be based on inventory availability and application requirements.

Q: Should I choose an Active status part over Not For New Designs?

A: Active status parts (Würth Elektronik, Chemi-Con, Panasonic) indicate ongoing manufacturer support and production. For new designs or long-term supply chain planning, Active status parts are preferable. For legacy system repair, any electrically equivalent part is suitable.

Q: Does the 0.02" height difference on Würth Elektronik and Chemi-Con parts matter?

A: Height difference is 0.846" versus 0.866" on the original. Verify available board clearance above the capacitor location. In most applications, this 0.02" (0.5 mm) reduction is not problematic, but space-constrained designs require confirmation.

Q: What is the advantage of Panasonic ECA-1JHG331B with extended temperature range?

A: The ECA-1JHG331B operates from -55°C to 105°C with 2000 Hrs lifetime at 105°C, compared to -40°C to 85°C on the original. This provides thermal margin for applications subject to higher ambient temperatures or thermal cycling, though it is not required for direct substitution.

Q: Are all parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.
