UPB1H221MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UPB1H221MPD is a 220 µF, 50 V aluminum electrolytic capacitor in radial, can package with a rated lifetime of 7000 hours at 105°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The UPB series represents a general-purpose aluminum electrolytic capacitor suitable for standard industrial and consumer electronics requiring stable capacitance and moderate ripple current handling.

Substitute Part Grouping Explanation

Substitution for the UPB1H221MPD is determined by strict equivalence across the following parameters: capacitance value (220 µF), voltage rating (50 V), tolerance (±20%), polarization (polar), lead spacing (5.00 mm), case diameter (10.00 mm), mounting type (through hole), and package type (radial, can). Parts are grouped into three categories based on product status and operational characteristics:

Category 1: Active Status Equivalents — Parts with active product status and matching electrical and mechanical specifications. These are preferred for new designs and ongoing production.

Category 2: Not For New Designs — Nichicon parts with equivalent specifications but discontinued from new design consideration. These remain suitable for legacy system maintenance and replacement.

Category 3: Last Time Buy / Obsolete — Parts with limited inventory or end-of-life status. These are suitable only for immediate replacement needs where inventory is available.

All substitute parts maintain the same capacitance, voltage rating, tolerance, polarization, lead spacing, case diameter, and through-hole mounting configuration as the original UPB1H221MPD.

Engineering Selection Recommendations

For Active Production: UPB1H221MPD1AA (Nichicon, active status) is the direct Nichicon equivalent with matching 7000-hour lifetime specification. Alternatively, Rubycon 50ZLJ220M10X16 and Chemi-Con EKZN500ELL221MJ16S offer active status with extended 10000-hour lifetime at 105°C, providing enhanced reliability for long-term applications.

For Legacy System Maintenance: UHE1H221MPD (Nichicon, not for new designs) provides matching 7000-hour lifetime with high inventory availability (224,453 pcs). This part is suitable for direct replacement in existing systems where the original UPB1H221MPD is no longer available.

For Immediate Replacement with Limited Inventory: 50YXH220MEFC10X16 (Rubycon, last time buy) matches the original 7000-hour lifetime specification and mechanical dimensions but has limited inventory (2,609 pcs).

Height-Constrained Applications: MAL214231221E3 (Vishay, active status) offers a reduced height of 14.60 mm compared to the standard 17.50 mm, suitable for space-limited designs. Note: This part has a shorter 2500-hour lifetime at 105°C.

All recommended substitutes maintain identical capacitance (220 µF), voltage rating (50 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different lifetime rating? A: Yes. The UPB1H221MPD has a 7000-hour lifetime at 105°C. Substitutes with equal or longer lifetimes (such as 10000-hour parts) are directly compatible. Parts with shorter lifetimes (such as 2500 or 4000 hours) are compatible electrically but may reduce system reliability in high-temperature or long-duration applications.

Q: Are all substitute parts RoHS compliant? A: Most active-status substitutes (Rubycon ZLH/ZLJ series, Chemi-Con KYB/KZN series) are ROHS3 compliant. The original UPB1H221MPD and Nichicon UPB1H221MPD1AA are not explicitly marked as RoHS compliant in the provided specifications. Verify RoHS compliance requirements for your specific application before selection.

Q: What is the difference between Nichicon UHD1H221MPD and UHE1H221MPD? A: Both are Nichicon parts marked "not for new designs." The UHD1H221MPD has a 4000-hour lifetime at 105°C, while UHE1H221MPD matches the original 7000-hour lifetime. For replacement applications, UHE1H221MPD is preferred due to equivalent lifetime performance and significantly higher inventory (224,453 pcs vs. 6,014 pcs).

Q: Can I substitute the Vishay MAL214231221E3 in all applications? A: The Vishay part is mechanically compatible (same lead spacing, case diameter, through-hole mounting) but has a reduced height (14.60 mm vs. 17.50 mm) and shorter lifetime (2500 hours vs. 7000 hours). Use this part only in space-constrained designs where the reduced height is required and the shorter lifetime is acceptable.

Q: What is the difference between 50ZLH220MEFCSZ10X16 and 50ZLH220MEFCUA10X16? A: Both are Rubycon ZLH series parts with identical electrical specifications (220 µF, 50 V, 10000-hour lifetime) and mechanical dimensions. The difference is in packaging or regional designation (SZ vs. UA suffix). Both are active-status parts suitable for direct substitution.

Q: Are there any compliance or certification differences between manufacturers? A: Rubycon and Chemi-Con substitutes are ROHS3 compliant. The original Nichicon UPB1H221MPD and UPB1H221MPD1AA do not carry explicit RoHS certification in the provided data. All parts are EAR99 classified and REACH unaffected or affected as noted. Verify specific compliance requirements for your application and region.
