ECO-S2GA330BA Equivalent & Substitute Parts

Part Overview

The ECO-S2GA330BA is a 33 µF, 400 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

The TS-HA series capacitor is designed for general-purpose applications requiring 400 V rated voltage with ±20% capacitance tolerance. The obsolete status necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECO-S2GA330BA are evaluated based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 400 V minimum (equal or higher acceptable)
• Tolerance: ±20% (matching tolerance class)
• Operating Temperature Range: -25°C to 105°C (minimum requirement)
• Lifetime: 3000 Hrs @ 105°C (minimum requirement)

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00 mm)
• Case Diameter: 0.866" (22.00 mm)
• Mounting Type: Through Hole
• Polarization: Polar

Substitutes are classified into two categories:

1. Direct Equivalent (381LX330M400H202): Identical electrical ratings (33 µF, 400 V, ±20%) with matching mechanical dimensions and snap-in package configuration.

2. Upgrade Alternative (381LX330M450H012): Higher voltage rating (450 V) with identical capacitance and tolerance, providing enhanced voltage margin while maintaining mechanical compatibility.

Engineering Selection Recommendations

For Direct Replacement (ECO-S2GA330BA → 381LX330M400H202):

The 381LX330M400H202 provides direct electrical and mechanical compatibility with identical 33 µF, 400 V specifications. This part is manufactured by Cornell Dubilier Electronics and maintains active product status with ROHS3 compliance. The snap-in package configuration and lead spacing are identical, enabling direct board-level substitution. Height dimension differs (0.866" vs. 1.063"), requiring verification of available board clearance in the target application.

For Upgraded Voltage Rating (ECO-S2GA330BA → 381LX330M450H012):

The 381LX330M450H012 offers a 50 V higher voltage rating (450 V) while maintaining identical 33 µF capacitance and ±20% tolerance. This part is active and ROHS3 compliant. The elevated voltage rating provides additional design margin for applications subject to voltage transients or overvoltage conditions. Mechanical dimensions match the original part exactly, including the 1.063" seated height, enabling direct substitution without clearance concerns.

Both substitute parts maintain the required operating temperature range (-25°C to 105°C) and 3000-hour lifetime specification at 105°C. Selection between direct equivalent and upgrade alternative depends on application voltage margin requirements and available board clearance.

Frequently Asked Questions (FAQ)

Q: Can the 381LX330M400H202 be used as a direct replacement for the ECO-S2GA330BA?

A: Yes. Both parts share identical electrical specifications (33 µF, 400 V, ±20% tolerance) and mechanical package configuration (radial, can snap-in, 10.00 mm lead spacing, 22.00 mm diameter). The primary difference is seated height: 0.866" for the 381LX330M400H202 versus 1.063" for the ECO-S2GA330BA. Verify available board clearance before substitution.

Q: What is the advantage of the 381LX330M450H012 upgrade option?

A: The 381LX330M450H012 provides a 50 V higher voltage rating (450 V vs. 400 V) while maintaining identical capacitance (33 µF) and tolerance (±20%). This higher voltage rating offers increased design margin for applications experiencing voltage transients or operating near maximum rated voltage. Seated height matches the original part (1.063"), eliminating clearance concerns.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 381LX330M400H202 and 381LX330M450H012 are ROHS3 compliant. The original ECO-S2GA330BA RoHS status is not specified in available documentation.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -25°C to 105°C with 3000-hour lifetime specification at 105°C.

Q: What is the difference in ripple current ratings between the main part and substitutes?

A: The ECO-S2GA330BA specifies 300 mA @ 120 Hz and 420 mA @ 100 kHz. The 381LX330M400H202 specifies 200 mA @ 120 Hz and 300 mA @ 20 kHz. The 381LX330M450H012 specifies 400 mA @ 120 Hz and 500 mA @ 20 kHz. Application ripple current requirements must be evaluated against the selected substitute part's ratings.

Q: Can both substitute parts be used interchangeably in the same application?

A: Both parts are mechanically compatible with identical lead spacing and case diameter. Electrical compatibility depends on application voltage requirements. For circuits operating at 400 V nominal, either part is acceptable. For circuits with voltage transient concerns or requiring additional margin, the 381LX330M450H012 (450 V) is preferred.
