UVZ2A101MPH Equivalent & Substitute Parts

Part Overview

The UVZ2A101MPH is a 100 µF, 100 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 part operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current performance.

Substitute Part Grouping Explanation

Substitution for the UVZ2A101MPH is determined by strict equivalence across the following parameters: capacitance (100 µF), voltage rating (100 V), tolerance (±20%), polarization (polar), package type (radial, can), lead spacing (0.197" / 5.00mm), and mounting type (through hole). Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Substitutes: Parts from the same manufacturer (Nichicon) with identical electrical specifications and physical dimensions. These include UVZ2A101MPD, which differs only in packaging format and product status.

Cross-Manufacturer Direct Equivalents: Parts from different manufacturers meeting all core electrical and mechanical parameters. EKMG101ELL101MJ20S (Chemi-Con) and ECA-2AHG101 (Panasonic) provide full parametric equivalence with identical capacitance, voltage, tolerance, lead spacing, and package dimensions.

Similar Functional Alternatives: Parts meeting core electrical specifications with minor dimensional variations. SEK101M100ST (Cornell Dubilier Electronics) maintains identical capacitance, voltage, and tolerance but differs in can diameter (0.512" vs 0.394") and height (0.787" vs 0.866"), requiring PCB layout verification before substitution.

Engineering Selection Recommendations

For Direct Replacement: UVZ2A101MPD provides the closest substitution as a Nichicon part with identical electrical and mechanical specifications. However, its "Not For New Designs" status limits application to legacy system maintenance only.

For New Designs and Active Production: EKMG101ELL101MJ20S (Chemi-Con) and ECA-2AHG101 (Panasonic) are preferred selections. Both parts are active products with ROHS3 compliance, matching all core parameters including capacitance, voltage, tolerance, lead spacing, and package dimensions. EKMG101ELL101MJ20S operates at 1000 hours lifetime at 105°C compared to the original 2000 hours; applications requiring extended thermal life should specify ECA-2AHG101.

For Space-Constrained Applications: ECA-2AHG101 maintains identical physical dimensions to the original part while offering active product status and full compliance certifications.

For Alternative Consideration: SEK101M100ST (Cornell Dubilier Electronics) meets all electrical specifications and offers 2000-hour lifetime at 105°C with ROHS3 compliance. The larger can diameter (0.512" vs 0.394") and reduced height (0.787" vs 0.866") require PCB layout verification to confirm mechanical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can UVZ2A101MPD be used as a direct replacement for UVZ2A101MPH? A: Yes, UVZ2A101MPD is electrically and mechanically identical to UVZ2A101MPH. However, its "Not For New Designs" status restricts use to legacy system repairs and maintenance applications only.

Q: What is the primary difference between EKMG101ELL101MJ20S and ECA-2AHG101? A: Both parts are cross-manufacturer equivalents with identical capacitance, voltage, tolerance, and physical dimensions. The key difference is thermal lifetime: EKMG101ELL101MJ20S is rated for 1000 hours at 105°C, while ECA-2AHG101 is rated for 2000 hours at 105°C, matching the original part's thermal performance.

Q: Can SEK101M100ST be used in existing PCB designs? A: SEK101M100ST meets all electrical specifications but has a larger can diameter (0.512" vs 0.394") and shorter height (0.787" vs 0.866"). PCB layout verification is required to confirm the component fits within the allocated space and does not interfere with adjacent components.

Q: Are all substitute parts RoHS compliant? A: Yes, all listed substitute parts (UVZ2A101MPD, EKMG101ELL101MJ20S, SEK101M100ST, and ECA-2AHG101) are ROHS3 compliant. The original UVZ2A101MPH is RoHS non-compliant.

Q: Which substitute part is recommended for new product designs? A: EKMG101ELL101MJ20S or ECA-2AHG101 are recommended for new designs. Both are active products with full compliance certifications. Select ECA-2AHG101 if 2000-hour thermal lifetime at 105°C is required; select EKMG101ELL101MJ20S if 1000-hour lifetime is acceptable.

Q: Do all substitute parts have identical lead spacing? A: Yes, all substitute parts maintain 0.197" (5.00mm) lead spacing, ensuring compatibility with existing PCB through-hole patterns.
