UVR2A102MHD Equivalent & Substitute Parts

Part Overview

The UVR2A102MHD is a 1000 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is classified as Not For New Designs. Due to its obsolescence status and limited availability (4996 pcs in stock), equivalent and upgraded substitute parts are necessary for ongoing production support and new design implementations. Substitute parts maintain the core electrical specifications while offering improved reliability characteristics or active product status.

Substitute Part Grouping Explanation

Substitution logic is based on the following allowed parameters: capacitance (1000 µF), voltage rating (100 V), tolerance (±20%), package type (radial can), mounting type (through hole), lead spacing (7.50 mm), case diameter (18.00 mm), and polarization (polar). Parts are grouped into three categories:

Direct Equivalents maintain identical electrical and mechanical specifications with equivalent lifetime ratings. These parts are interchangeable without design modification.

Upgraded Substitutes maintain all core electrical and mechanical parameters but offer extended lifetime ratings at higher temperatures (105°C operation vs. 85°C), improved ripple current handling, or lower impedance characteristics. These parts provide enhanced reliability for the same footprint and electrical performance.

Cross-Manufacturer Equivalents from alternative manufacturers (Cornell Dubilier, Panasonic, Rubycon, EPCOS, Chemi-Con) meet identical electrical specifications and mechanical dimensions, enabling multi-source procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can UVK2A102MHD replace UVR2A102MHD in existing designs? A: UVK2A102MHD is electrically equivalent with identical capacitance (1000 µF), voltage (100 V), tolerance (±20%), and lifetime (2000 Hrs @ 85°C). However, the height is reduced from 1.654" to 1.398", requiring verification that PCB clearance and mounting constraints are satisfied.

Q: What is the difference between direct equivalents and upgraded substitutes? A: Direct equivalents maintain identical lifetime ratings (2000 Hrs @ 85°C). Upgraded substitutes extend lifetime to 3000-10000 hours at 105°C operation while maintaining all electrical and mechanical specifications. Upgraded parts provide enhanced reliability for the same footprint and electrical performance.

Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best long-term availability? A: 108CKS100MRY (Cornell Dubilier) carries Active product status with the highest inventory (24530 pcs). EKYB101ELL102MM40S and EKZN101ELL102MM40S (Chemi-Con) also carry Active status with extended 10000-hour lifetime ratings at 105°C.

Q: Do all substitutes fit the same PCB footprint? A: All parts share identical lead spacing (7.50 mm) and case diameter (18.00 mm). Height varies from 1.398" to 1.654". PCB layout must accommodate the specific height of the selected substitute to ensure proper clearance and mounting stability.

Q: What ripple current specifications should I consider? A: Ripple current ratings vary among substitutes. UHW2A102MHD, EKYB101ELL102MM40S, and EKZN101ELL102MM40S provide the highest ripple current handling at high frequencies (4.61-3.86 A @ 100 kHz), suitable for demanding power supply applications.
