Engineering Selection Recommendations

Direct Parametric Equivalent: UVY1J331MPD is a direct parametric equivalent to UVZ1J331MPD. Both parts share identical electrical specifications (330 µF, 63 V, ±20%), mechanical dimensions (0.394" diameter, 0.866" height, 0.197" lead spacing), and lifetime rating (2000 Hrs @ 105°C). Both are classified as Not For New Designs. This part provides a direct substitution path with no design modifications required.

Active Product Alternatives: URZ1J331MHD, EKMG630ELL331MJ20S, and EKMQ630ELL331MJ20S are active products with current manufacturing status. URZ1J331MHD matches the electrical and thermal specifications of UVZ1J331MPD but features a reduced height (0.650" vs. 0.866"), requiring verification of PCB clearance constraints. EKMG630ELL331MJ20S (Chemi-Con KMG series, 1000 Hrs) and EKMQ630ELL331MJ20S (Chemi-Con KMQ series, 2000 Hrs) provide equivalent electrical and mechanical specifications with active product status, supporting long-term supply continuity.

Performance-Enhanced Substitutes: UPJ1J331MHD, UPM1J331MHD, and UPW1J331MHD offer extended lifetime ratings (5000 Hrs and 7000 Hrs respectively) compared to the original 2000-hour specification. These parts require mechanical compatibility verification due to increased case diameters (0.492" to 0.709") and height variations. UPM series parts include AEC-Q200 automotive qualification. Selection of performance-enhanced substitutes is appropriate when design margins permit increased component size and when extended operational life is beneficial.

Compliance Considerations: All listed parts maintain ROHS3 compliance. UPM1J331MHD and UPM1J331MHD6 are REACH Affected; all other parts are REACH Unaffected. Component selection should align with supply chain compliance requirements and end-application regulatory obligations.

Frequently Asked Questions (FAQ)

Q: Can UVY1J331MPD directly replace UVZ1J331MPD without PCB modifications? A: Yes. UVY1J331MPD is a direct parametric equivalent with identical electrical specifications, mechanical dimensions, lead spacing (0.197"), case diameter (0.394"), and height (0.866"). No PCB layout changes are required.

Q: What is the primary difference between UVZ1J331MPD and the UPJ/UPM/UPW series? A: The primary differences are lifetime rating and case size. UVZ offers 2000 Hrs @ 105°C in a 10.00 mm diameter case. UPJ, UPM, and UPW series provide 5000 Hrs and 7000 Hrs ratings in larger 12.50 mm and 18.00 mm diameter cases. These larger packages require PCB space verification before substitution.

Q: Are Chemi-Con EKMG and EKMQ series parts suitable replacements? A: Yes, for applications where active product status is required. EKMG630ELL331MJ20S and EKMQ630ELL331MJ20S match the electrical specifications and mechanical dimensions of UVZ1J331MPD. EKMQ provides the same 2000-hour lifetime; EKMG provides 1000 hours. Both are currently in active production.

Q: What is the significance of the lead spacing parameter? A: Lead spacing determines PCB footprint compatibility. UVZ1J331MPD uses 0.197" (5.00 mm) spacing. Substitutes with identical spacing (UVY1J331MPD, UPM1J331MHD, EKMG630ELL331MJ20S, EKMQ630ELL331MJ20S) are direct mechanical fits. Parts with 0.295" (7.50 mm) spacing (UPJ1J331MHD6, UPM1J331MHD6) require PCB redesign.

Q: Why do some substitutes have larger case diameters? A: Larger case diameters (0.492" and 0.709") accommodate higher ripple current ratings and extended lifetime specifications. These design enhancements require increased physical volume. PCB layout must provide adequate clearance before substitution.

Q: Can URZ1J331MHD be used as a direct replacement despite its reduced height? A: URZ1J331MHD maintains electrical equivalence and lead spacing compatibility but features reduced height (0.650" vs. 0.866"). Substitution is mechanically feasible only if PCB clearance constraints permit the shorter profile. Verify component placement and surrounding circuit elements before implementation.

Q: What compliance certifications apply to these parts? A: All listed parts are ROHS3 compliant. UPM series parts (UPM1J331MHD, UPM1J331MHD6) carry AEC-Q200 automotive qualification and are REACH Affected. All other parts are REACH Unaffected. Select parts based on end-application regulatory requirements.

Q: How does product status affect component selection? A: UVZ1J331MPD is classified as Not For New Designs, indicating end-of-life status. For new designs, select active products: URZ1J331MHD, EKMG630ELL331MJ20S, or EKMQ630ELL331MJ20S. For existing designs requiring replacement, UVY1J331MPD provides direct equivalence; active alternatives ensure long-term supply availability.
