Equivalent & Substitute Parts for ECO-S2GP101AA

Part Overview

The Panasonic ECO-S2GP101AA is a 100 µF, 400 V aluminum electrolytic capacitor in radial, can snap-in package with through-hole mounting. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production support. The part operates across a temperature range of -25°C to 85°C with a rated lifetime of 2000 hours at 85°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECO-S2GP101AA is determined by the following mandatory parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 400 V minimum (equal or higher voltage acceptable)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.787" Dia (20.00mm) (exact match required)
• Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical compatibility criteria. Variations in lifetime rating, operating temperature range, and ripple current specifications are secondary considerations that do not prevent functional substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All four Nichicon substitute parts satisfy the mandatory electrical and mechanical compatibility requirements for the ECO-S2GP101AA. Selection among these alternatives depends on application-specific constraints:

LLS2G101MELY provides direct voltage and temperature equivalence to the original part while offering improved lifetime (3000 hours at 85°C versus 2000 hours). This part is the closest functional match and is recommended for applications with identical thermal and operational profiles. Height is reduced to 1.181" (30.00mm), which may provide PCB layout advantages.

LGU2G101MELY extends the operating temperature range to 105°C and provides 3000-hour lifetime at that elevated temperature. This part is suitable for applications requiring higher thermal margin or operation in warmer environments. Physical dimensions match the original part exactly.

LGUW6101MELY offers the highest voltage rating at 420 V, providing additional voltage margin over the original 400 V specification. Operating temperature extends to 105°C with 3000-hour lifetime. This part is appropriate for applications where voltage headroom is beneficial or where thermal performance is critical.

LLS2W101MELY provides the highest voltage rating at 450 V with 3000-hour lifetime at 85°C. This part is suitable for applications requiring maximum voltage margin while maintaining the original operating temperature range.

All substitute parts carry ROHS3 compliance and REACH unaffected status, addressing regulatory requirements not met by the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can LLS2G101MELY be used as a direct replacement for ECO-S2GP101AA?

A: Yes. LLS2G101MELY matches all mandatory parameters: 100 µF capacitance, ±20% tolerance, 400 V rating, radial snap-in package, through-hole mounting, 10.00mm lead spacing, and 20.00mm diameter. The reduced height (30.00mm versus 35.00mm) is mechanically compatible with standard PCB layouts designed for the original part.

Q: What is the difference between LGU2G101MELY and LLS2G101MELY?

A: Both parts share identical electrical specifications (100 µF, ±20%, 400 V) and physical dimensions. LGU2G101MELY extends the operating temperature range to 105°C and provides 3000-hour lifetime at that temperature, whereas LLS2G101MELY operates to 85°C with 3000-hour lifetime at 85°C. LGU2G101MELY is preferred for applications requiring higher thermal performance.

Q: Why do LGUW6101MELY and LLS2W101MELY have higher voltage ratings?

A: These parts are rated at 420 V and 450 V respectively, compared to the original 400 V specification. Higher voltage ratings provide additional safety margin in applications subject to voltage transients or where design margins are critical. These parts are electrically and mechanically compatible with 400 V circuit designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four Nichicon substitute parts carry ROHS3 compliance certification, whereas the original Panasonic ECO-S2GP101AA is RoHS non-compliant. This compliance is mandatory for many modern applications and regulatory environments.

Q: Will the reduced height of LLS2G101MELY affect PCB layout?

A: LLS2G101MELY has a maximum seated height of 30.00mm compared to 35.00mm for the original part and other substitutes. This 5.00mm reduction is mechanically compatible with standard through-hole PCB designs and may provide layout advantages. No circuit modifications are required.

Q: What is the inventory status of these substitute parts?

A: LLS2G101MELY: 724 pcs, LGU2G101MELY: 918 pcs, LGUW6101MELY: 1051 pcs, LLS2W101MELY: 869 pcs. All parts are available as new original stock from Nichicon.
