EET-UQ2W820BA Equivalent & Substitute Parts

Part Overview

The EET-UQ2W820BA is a 82 µF, 450 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making substitute components necessary for new designs and ongoing production requirements. The TS-UQ series specifications establish the baseline parameters for identifying compatible alternatives across multiple manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the EET-UQ2W820BA are identified based on strict electrical and mechanical compatibility criteria. All substitute candidates must match the following parameters:

Capacitance: 82 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -25°C ~ 85°C minimum (equal or broader range acceptable)
Polarization: Polar (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Physical Dimensions: 0.866" Dia (22.00mm) and 0.984" Height (25.00mm) (exact match required)

All four substitute parts listed meet these core compatibility requirements. Variations in ESR, ripple current ratings, and lifetime specifications do not affect direct substitutability for general purpose applications.

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically compatible with the EET-UQ2W820BA. Selection among these alternatives should be based on the following factors:

Product Status & Availability: The 450USG82MEFCSN20X25 (Rubycon), ESMQ451VSN820MP25S (Chemi-Con), and LLS2W820MELZ (Nichicon) are all active products with confirmed inventory availability. The original Panasonic part is obsolete.

Compliance & Certifications: All substitute parts carry RoHS3 compliance or equivalent. The Rubycon and Nichicon parts explicitly state ROHS3 Compliant status. The Chemi-Con part is RoHS Compliant. All parts are classified under ECCN EAR99 and HTSUS 8532.22.0040.

Operational Longevity: The Rubycon (450USG82MEFCSN20X25) and Nichicon (LLS2W820MELZ) parts offer extended lifetime ratings of 3000 hours at 85°C, compared to 2000 hours for the original Panasonic and Chemi-Con parts.

Physical Compatibility: All substitute parts maintain identical lead spacing (0.394" / 10.00mm), diameter (0.866" / 22.00mm), and height (0.984" / 25.00mm) specifications, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the EET-UQ2W820BA?

A: Yes. All four substitute parts meet the core electrical and mechanical compatibility requirements: 82 µF capacitance, 450 V voltage rating, ±20% tolerance, identical physical dimensions, and through-hole snap-in package configuration. No circuit modifications are required.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, product status, and operational lifetime. The Rubycon and Nichicon parts offer 3000-hour lifetime ratings at 85°C, while the Panasonic original and Chemi-Con substitute provide 2000-hour ratings. All parts maintain identical electrical specifications for general purpose applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Rubycon and Nichicon parts are explicitly ROHS3 Compliant. The Chemi-Con part is RoHS Compliant. All parts meet current environmental and regulatory requirements.

Q: Does the difference in ripple current ratings affect substitutability?

A: No. All substitute parts maintain ripple current ratings within acceptable ranges for the 82 µF, 450 V snap-in capacitor category. Variations between 800 mA and 830 mA at 120 Hz, and between 1.144 A and 1.187 A at high frequency, do not impact general purpose application compatibility.

Q: What is the lead spacing for these parts?

A: All parts, including the original and substitutes, have a lead spacing of 0.394" (10.00mm), ensuring compatibility with existing PCB layouts designed for the EET-UQ2W820BA.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts are electrically and mechanically equivalent. They can be used interchangeably within the same circuit or across different production batches without affecting circuit performance or reliability.
