Equivalent & Substitute Parts for UPB1H101MPD

Part Overview

The UPB1H101MPD is a 100 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The UPB series operates across a temperature range of -40°C to 105°C with a rated lifetime of 5000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution of the UPB1H101MPD is determined by strict equivalence across the following critical parameters:

Capacitance value: 100 µF (exact match required)
Voltage rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can (exact match required)
Lead spacing: 0.138" (4.60 mm) (exact match required)
Case diameter: 0.315" (8.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Operating temperature range: -40°C to 105°C (exact match required)

Substitute parts are grouped into two categories: direct substitutes (identical electrical and mechanical specifications) and similar substitutes (meeting core electrical requirements with acceptable variations in lifetime or ripple current ratings). Height variations within the radial can package are permissible when lead spacing and case diameter remain constant, as these dimensions control PCB footprint compatibility.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: UTS1H101MPD1TA (Nichicon), 107KBM050MFH (Cornell Dubilier / Illinois Capacitor), 50YXJ100M8X11.5 (Rubycon), 50YXJ100MCE8X11.5 (Rubycon), 50YXM100MEFR8X11.5 (Rubycon), or 50ZLH100MEFCM18X11.5 (Rubycon).

For replacement of existing UPB1H101MPD units in fielded equipment, UTS1H101MPD1TA provides the closest electrical match with identical 5000-hour lifetime at 105°C and maintains the same case diameter and lead spacing. This part carries RoHS3 compliance and REACH Unaffected status.

For applications requiring extended operational life, 50YXM100MEFR8X11.5 offers 10000 hours at 105°C with RoHS3 compliance. The 50YXJ100M8X11.5 and 50YXJ100MCE8X11.5 provide 7000-hour lifetime ratings with higher ripple current capacity and RoHS3 compliance.

All substitute parts maintain identical capacitance, voltage rating, tolerance, lead spacing, case diameter, and through-hole mounting configuration. Height variations are within acceptable limits for standard PCB layouts using 0.138" (4.60 mm) lead spacing.

Frequently Asked Questions (FAQ)

Q: Can UPB1H101MPD be directly replaced with UTS1H101MPD1TA?

A: Yes. Both parts share identical electrical specifications (100 µF, 50 V, ±20% tolerance, 5000-hour lifetime at 105°C) and mechanical dimensions (0.138" lead spacing, 0.315" case diameter, through-hole mounting). Height difference (0.512" vs. 0.413") does not affect PCB compatibility. UTS1H101MPD1TA is Active status with RoHS3 compliance.

Q: What is the difference between Nichicon and Rubycon substitutes?

A: Both manufacturers provide 100 µF, 50 V radial can capacitors with identical lead spacing and case diameter. Differences exist in lifetime ratings (3000 to 10000 hours at 105°C), ripple current capacity, and product status. Selection depends on application requirements for operational life and ripple current handling.

Q: Are height variations significant for PCB layout?

A: Height variations (0.413" to 0.531") are acceptable for through-hole radial can packages when lead spacing (0.138") and case diameter (0.315") remain constant. These dimensions control PCB footprint compatibility. Verify clearance in your specific layout if space is constrained.

Q: Which substitute offers the longest operational life?

A: 50YXM100MEFR8X11.5 provides 10000 hours at 105°C, the highest rating among available substitutes. This part is Active status with RoHS3 compliance and maintains identical electrical and mechanical specifications.

Q: Can I use parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status (UHE1H101MPD, UHD1H101MPD, 50YXH100MEFC8X11.5) are suitable for replacement in existing equipment but should not be selected for new product development. For new designs, use only Active status parts.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. All Active status substitutes carry RoHS3 compliance. This is relevant for products sold in regulated markets requiring hazardous substance restrictions.
