UHD1H151MPD Equivalent & Substitute Parts

Part Overview

The UHD1H151MPD is a 150 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. The UHD series offers a 4000-hour lifetime rating at 105°C with general-purpose applications. Due to its discontinued status, equivalent and upgraded substitute parts from active product lines are necessary for ongoing production, maintenance, and new design implementations.

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and suitable for direct replacement of the UHD1H151MPD in through-hole applications. Selection should prioritize parts with Active product status for new designs and long-term supply assurance.

For equivalent performance with extended lifetime:

UHE1H151MPD (Nichicon) provides 7000-hour rating with identical electrical specifications, though height is reduced to 0.492 inches.
50ZLH150MEFC10X12.5 (Rubycon) offers the highest lifetime rating at 10000 hours with matching form factor.

For automotive applications:

B41888D6157M (EPCOS - TDK Electronics) carries AEC-Q200 qualification with 7000-hour lifetime and extended temperature range to -55°C.
B41858C6157M000 (EPCOS - TDK Electronics) provides automotive-grade reliability with 5000-hour lifetime.

For general-purpose applications with active product status:

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height? A: Yes, provided the lead spacing (0.197 inches / 5.00 mm) remains identical. Height variations between 0.492 and 0.551 inches are acceptable for through-hole mounting, as they do not affect electrical performance or PCB footprint compatibility. Verify clearance in your specific application.

Q: What is the difference between parts with different lifetime ratings? A: Lifetime rating indicates the number of hours a capacitor maintains its specified electrical characteristics at maximum rated temperature (105°C). Higher lifetime ratings (9000-10000 hours) provide extended operational reliability compared to the original 4000-hour specification. Selection depends on application requirements and expected service life.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions for electronic components.

Q: Can I use automotive-grade parts (B41858C6157M000, B41888D6157M) in general-purpose applications? A: Yes. Automotive-grade parts meet or exceed general-purpose specifications and are electrically compatible. They offer additional reliability margins and extended temperature ranges (-55°C minimum vs. -40°C), making them suitable for any application requiring the 150 µF, 50 V specification.

Q: What does "Not For New Designs" mean for the UHD1H151MPD? A: This designation indicates the part has been discontinued by the manufacturer and is no longer recommended for new product development. Existing inventory may be available, but long-term supply cannot be assured. Active substitute parts should be selected for new designs.

Q: Are there differences in ripple current handling between substitute parts? A: Yes. Ripple current ratings vary by manufacturer and series. Verify that the selected substitute meets or exceeds your application's ripple current requirements at both 120 Hz (low frequency) and 100 kHz (high frequency) operating conditions.

Q: Can I mix different substitute parts in the same circuit board? A: Yes, all listed parts are electrically equivalent and mechanically compatible. Mixing different manufacturers or series in the same design is acceptable from a functional standpoint, though using a single part number per design simplifies procurement and inventory management.
