UPB2C151MHD Equivalent & Substitute Parts

Part Overview

The Nichicon UPB2C151MHD is a 150 µF, 160 V aluminum electrolytic capacitor in radial, can package format with a rated lifetime of 5000 hours at 105°C. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing design support and production continuity. Substitute parts are selected based on matching or exceeding electrical performance within the same mechanical footprint and mounting configuration.

Substitute Part Grouping Explanation

Substitution is determined by the following criteria:

Primary Matching Parameters:

Capacitance: 150 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 160 V minimum (equal or higher acceptable)
Lead Spacing: 0.295" (7.50mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Considerations:

Case diameter and height must accommodate the original footprint or be compatible with PCB layout
Lifetime rating and operating temperature range may vary
Ripple current specifications must meet or exceed application requirements

Substitute parts are categorized as:

Upgrade: Higher voltage rating or extended lifetime with identical mechanical footprint
Direct: Equivalent electrical and mechanical specifications from alternative manufacturers
Similar: Matching core specifications with minor dimensional variations

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): EEU-EB2C151S (Panasonic) provides identical 150 µF, 160 V, ±20% specifications with matching case diameter (18.00mm) and lead spacing (7.50mm). This part is active status and RoHS3 compliant, making it suitable for direct substitution in existing designs.

For Upgraded Performance (Higher Voltage Rating): UCS2E151MHD or UCY2E151MHD (Nichicon) offer 250 V rating with extended lifetime (10000-12000 hours) while maintaining identical mechanical footprint. These upgrades provide enhanced reliability margin and are recommended for applications requiring improved voltage headroom or extended service life.

For Alternative Manufacturer Options: EEU-EB2D151S (Panasonic, 200 V) and EKXG201ELL151MM25S (Chemi-Con, 200 V) provide intermediate voltage ratings with active product status and RoHS3 compliance. Both maintain the 18.00mm case diameter and 7.50mm lead spacing.

Compliance Considerations: All recommended substitutes are RoHS3 compliant. UCY2E151MHD carries REACH Affected status; verify regulatory requirements for your application region before selection.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A capacitor rated for 200 V or 250 V can replace the 160 V UPB2C151MHD, provided all other parameters (capacitance, tolerance, lead spacing, case diameter) match. Higher voltage ratings provide additional safety margin without affecting circuit operation.

Q: What is the significance of the case diameter and height dimensions? A: These dimensions determine PCB footprint compatibility. The original UPB2C151MHD uses 18.00mm diameter and 26.50mm height. Substitutes with identical dimensions (UCS2E151MHD, UCY2E151MHD, EEU-EB2D151S, EKXG201ELL151MM25S) are direct mechanical replacements. Parts with different dimensions (16.00mm or 33.00mm height) require PCB layout verification.

Q: Does lifetime rating affect substitution compatibility? A: Lifetime rating indicates expected operational hours at maximum temperature. Extended lifetime (10000-12000 hours) represents improved reliability but does not prevent substitution. Select based on application duty cycle and reliability requirements.

Q: Are there any lead spacing considerations? A: All listed substitutes maintain the 0.295" (7.50mm) lead spacing, ensuring compatibility with existing PCB hole patterns. This parameter is non-negotiable for through-hole mounting.

Q: What is the difference between Nichicon, Panasonic, Rubycon, and Chemi-Con options? A: These are different manufacturers producing equivalent aluminum electrolytic capacitors. All listed parts meet the same electrical specifications and mechanical requirements. Selection may depend on supply chain availability, cost, or specific compliance certifications required by your application.

Q: Can I substitute a part with different tolerance? A: No. All listed substitutes maintain ±20% tolerance to match the original specification. Tolerance directly affects circuit performance and must remain constant.
