Engineering Selection Recommendations

Direct Replacement (Identical Specifications): UPS1H151MPD1TD is the direct equivalent, differing only in packaging format (Cut Tape vs. Bulk). Both are Nichicon UPS series components with identical electrical and mechanical specifications. Selection between these depends on procurement and assembly requirements.

Active Product Alternatives (Recommended for New Procurement): All remaining substitute parts are classified as Active products, making them suitable for ongoing procurement and new applications. Selection among these alternatives depends on specific application constraints:

157KXM050M (Cornell Dubilier): Maintains original height specification (0.551"), suitable for space-constrained PCB layouts. Active product status ensures long-term availability.
B41858C6157M000 and B41888D6157M (EPCOS - TDK Electronics): Both feature reduced height (0.531"), providing PCB layout flexibility. B41888D6157M offers extended lifetime (7000 hours) and lower impedance (203 mOhms), supporting applications requiring enhanced thermal stability and lower ESR performance.
MAL215051151E3 (Vishay): Compact height (0.531") with AEC-Q200 automotive qualification and 4000-hour lifetime rating.
EEU-FC1H151 and EEU-FC1H151B (Panasonic): Lowest impedance (119 mOhms) among all alternatives, beneficial for high-ripple-current applications. Both carry AEC-Q200 automotive qualification. Height variation (0.630" and 0.669") requires PCB layout verification.

Nichicon UPM1H151MPD Consideration: While electrically compatible, this part features increased height (0.866"), requiring PCB layout verification before selection. Extended lifetime (5000 hours) and lower impedance (100 mOhms) may benefit specific applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for UPS1H151MPD? A: Yes, all listed parts meet the critical electrical and mechanical parameters: 150 µF capacitance, 50 V voltage rating, ±20% tolerance, radial can package, 0.197" lead spacing, 0.394" case diameter, and through-hole mounting. However, verify PCB height clearance, as some alternatives have different maximum heights.

Q: What is the difference between UPS1H151MPD and UPS1H151MPD1TD? A: These are identical Nichicon UPS series components with the same electrical and mechanical specifications. The difference is packaging: UPS1H151MPD is supplied in Bulk packaging, while UPS1H151MPD1TD is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements.

Q: Why are some substitute parts taller than the original? A: Capacitor height varies by manufacturer design and internal construction. UPM1H151MPD (22.00 mm) and EEU-FC1H151B (17.00 mm) are taller than the original UPS1H151MPD (14.00 mm). Verify PCB layout clearance before selection. Shorter alternatives include B41858C6157M000 and MAL215051151E3 (both 14.60 mm).

Q: What does "Not For New Designs" mean for the original part? A: This status indicates the UPS1H151MPD has reached end-of-life and is no longer recommended for new product development. Existing inventory remains available for maintenance and repair. For new designs, select from Active status alternatives such as 157KXM050M, B41858C6157M000, B41888D6157M, MAL215051151E3, EEU-FC1H151, or EEU-FC1H151B.

Q: How do I choose between Active alternatives? A: Consider three factors: (1) PCB layout constraints—verify height compatibility; (2) thermal performance—higher lifetime ratings (5000-7000 hours) support demanding applications; (3) impedance requirements—lower impedance values (100-203 mOhms) reduce voltage ripple in high-current circuits. All alternatives maintain the same 150 µF, 50 V electrical core specification.

Q: Are these parts RoHS compliant? A: Yes, all listed parts are ROHS3 compliant, meeting environmental and hazardous substance restrictions.

Q: Do any of these parts have automotive qualification? A: Yes, UPM1H151MPD, B41888D6157M, MAL215051151E3, EEU-FC1H151, and EEU-FC1H151B carry AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications.
