Engineering Selection Recommendations

For Direct Replacement (Same Specifications): UPS2D330MHD1TO is the direct equivalent available in Cut Tape packaging. Both maintain identical electrical specifications and 3000-hour lifetime rating at 105°C. Selection between bulk and cut tape depends on procurement and assembly requirements.

For Active Product Status: UCS2E330MHD (Manufacturer Recommended) is an active product with identical capacitance and mechanical compatibility. It provides 250 V rating and 10000-hour lifetime, exceeding the original specification. This part is suitable for new designs and ongoing production where higher reliability margins are required.

UCY2G330MHD (Upgrade) offers 400 V rating and 12000-hour lifetime with active product status. Physical dimensions remain compatible with the original footprint. This part is appropriate for applications requiring enhanced voltage headroom and extended operational life.

For Dimension-Constrained Applications: UCY2D330MPD and UAS2D330MPD feature reduced diameter (0.394" vs. 0.492") while maintaining 200 V rating and through-hole mounting. These parts are suitable for space-limited PCB layouts. UCY2D330MPD provides superior 12000-hour lifetime; UAS2D330MPD offers 2000-hour lifetime with active status.

For Compact Height Requirements: UCS2E330MHD, UCY2D330MPD, and UAS2D330MPD all feature reduced height compared to the original part, ranging from 0.846" to 0.866" versus 1.063". These are applicable where vertical clearance is constrained.

For Lower Lifetime Tolerance: URZ2D330MHD is active but rated for only 1000 hours at 105°C and features different lead spacing (0.295" vs. 0.197"). This part is not recommended as a direct substitute due to mechanical incompatibility and significantly reduced lifetime.

All recommended substitutes maintain ROHS3 compliance and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can UCS2E330MHD replace UPS2D330MHD directly? A: UCS2E330MHD is electrically compatible with 250 V rating (exceeding the 200 V requirement) and identical 33 µF capacitance. Physical dimensions and lead spacing are identical. The primary difference is reduced height (0.846" vs. 1.063") and extended lifetime (10000 vs. 3000 hours). Direct PCB substitution is possible if vertical clearance permits.

Q: What is the difference between UPS2D330MHD and UPS2D330MHD1TO? A: Both parts are electrically and mechanically identical with 33 µF, 200 V, 3000-hour specifications. The primary difference is packaging: UPS2D330MHD is supplied in bulk, while UPS2D330MHD1TO is supplied in cut tape format. Selection depends on assembly process requirements.

Q: Why do some substitutes have different physical dimensions? A: Nichicon manufactures 33 µF, 200 V capacitors across multiple series (UPS, UPW, UCS, UCY, UAQ, UAS, URZ) with varying lifetime ratings and physical form factors. Higher lifetime ratings often result in different case sizes. Substitutes with reduced diameter or height may be selected for space-constrained applications, provided lead spacing and mounting type remain compatible.

Q: Is UCY2G330MHD suitable for a 200 V application? A: Yes. UCY2G330MHD is rated for 400 V, which exceeds the 200 V requirement. Higher voltage ratings provide additional safety margin and are electrically compatible with lower-voltage applications. This part is recommended for new designs requiring extended operational life (12000 hours).

Q: What does "Not For New Designs" mean for UPS2D330MHD1TO? A: This product status indicates the part is available for existing production and maintenance but should not be selected for new circuit designs. For new designs, active products such as UCS2E330MHD or UCY2G330MHD are recommended.

Q: Can I use URZ2D330MHD as a substitute? A: URZ2D330MHD has different lead spacing (0.295" vs. 0.197") and physical dimensions, making it mechanically incompatible with the original PCB footprint. Additionally, the 1000-hour lifetime is significantly lower than the original 3000-hour rating. This part is not recommended as a direct substitute.

Q: What is the impact of reduced height on PCB design? A: Parts with reduced height (such as UCS2E330MHD at 0.846") occupy less vertical space, allowing for improved component density or clearance from adjacent components. If the original design has vertical clearance constraints, these parts provide a compatible alternative. Verify that the reduced height does not conflict with other design requirements.
