ECO-S2GP820AA Equivalent & Substitute Parts

Part Overview

The ECO-S2GP820AA is an 82 µF, 400 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-UP series. This radial, can-style snap-in capacitor is designed for general purpose applications with a rated lifetime of 2000 hours at 85°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring this capacitance and voltage rating.

Substitute Part Grouping Explanation

Substitution for the ECO-S2GP820AA is determined by strict equivalence in the following parameters:

Capacitance: 82 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Physical Dimensions: 0.787" Dia × 1.181" Height (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

The substitute parts identified—LGU2G820MELY and LLS2G820MELY, both manufactured by Nichicon—meet all these electrical and mechanical requirements. Both are active products with improved lifetime ratings and enhanced compliance certifications compared to the obsolete ECO-S2GP820AA.

Engineering Selection Recommendations

Both LGU2G820MELY and LLS2G820MELY are direct functional equivalents to the ECO-S2GP820AA with identical electrical and mechanical specifications. Selection between them depends on application requirements:

LGU2G820MELY is suitable for applications requiring extended operating temperature range up to 105°C and extended lifetime rating of 3000 hours at that elevated temperature. This part offers the broadest thermal operating envelope.

LLS2G820MELY maintains the original operating temperature range of -25°C to 85°C while providing improved lifetime of 3000 hours at 85°C compared to the original 2000 hours. This part is appropriate for applications with standard thermal requirements.

Both substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory advantages over the obsolete ECO-S2GP820AA. Both are currently in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can LGU2G820MELY and LLS2G820MELY be used interchangeably with ECO-S2GP820AA?

A: Yes. Both parts are direct substitutes meeting identical capacitance, voltage, tolerance, and physical specifications. The primary differences are product status (active vs. obsolete), compliance certifications, and lifetime ratings at temperature.

Q: What is the difference between LGU2G820MELY and LLS2G820MELY?

A: Both parts share identical electrical and mechanical specifications. LGU2G820MELY operates to 105°C with 3000-hour lifetime at that temperature. LLS2G820MELY operates to 85°C with 3000-hour lifetime at that temperature. Selection depends on the maximum operating temperature required by your application.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts—ECO-S2GP820AA, LGU2G820MELY, and LLS2G820MELY—have identical lead spacing (0.394" / 10.00 mm), diameter (0.787" / 20.00 mm), and maximum height (1.181" / 30.00 mm). They are mechanically interchangeable in through-hole snap-in mounting applications.

Q: Why is the ECO-S2GP820AA obsolete?

A: The ECO-S2GP820AA is listed as obsolete by Panasonic. Nichicon's LGU2G820MELY and LLS2G820MELY are active products providing equivalent or superior performance characteristics and are recommended for new designs and ongoing production requirements.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both LGU2G820MELY and LLS2G820MELY are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original ECO-S2GP820AA is RoHS non-compliant.
