Package Type: Must be Radial, Can - Snap-In
Lead Spacing: Must be 0.394" (10.00 mm)
Case Diameter: Must be 0.866" (22.00 mm) for direct substitutes; larger diameters indicate mechanical incompatibility

Parts are categorized as follows:

Direct Substitutes (160 V rated, identical mechanical footprint):

160MXG470MEFCSN22X25 (Rubycon MXG series)
LGN2C471MELZ25 (Nichicon LGN series)
EKMQ161VSN471MP25S (Chemi-Con KMQ series)

Upgrade Options (Higher voltage ratings, same mechanical footprint):

LGG2D471MELZ25 (Nichicon LGG series, 200 V)
LGG2Z471MELZ25 (Nichicon LGG series, 180 V)

Similar Parts (160 V rated, different mechanical dimensions):

381LX471M160A202 (Cornell Dubilier 381LX series, 35.00 mm diameter)
381LX471M160H022 (Cornell Dubilier 381LX series, 32.00 mm height)

Engineering Selection Recommendations

For Direct Replacement (Identical Footprint, 160 V Rating):

Select from 160MXG470MEFCSN22X25, LGN2C471MELZ25, or EKMQ161VSN471MP25S when PCB layout constraints require exact mechanical compatibility with the original EET-HC2C471BA. All three options are active products with ROHS3 compliance. The Rubycon and Nichicon options offer extended lifetime ratings (3000 hours at 105°C) compared to the original specification (2000 hours).

For Voltage Upgrade (Same Footprint, Higher Rating):

LGG2D471MELZ25 (200 V) and LGG2Z471MELZ25 (180 V) maintain identical mechanical dimensions while providing higher voltage margins. These are suitable for designs requiring increased voltage headroom. Both are active Nichicon products with ROHS3 compliance.

For Mechanical Accommodation (Different Footprint):

381LX471M160H022 (Cornell Dubilier) provides a 160 V equivalent with increased height (32.00 mm vs. 27.00 mm) and extended lifetime (3000 hours). This option is viable only if PCB layout permits the additional height. The 381LX471M160A202 variant has a larger diameter (35.00 mm) and is suitable only for applications with sufficient board space.

All substitute options carry ROHS3 compliance and are classified as active products, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V rated capacitor in place of a 160 V rated capacitor?

A: Yes. Higher voltage ratings are electrically compatible with lower voltage applications. The LGG2D471MELZ25 (200 V) and LGG2Z471MELZ25 (180 V) are suitable upgrades that maintain the same mechanical footprint and capacitance value.

Q: What is the difference between direct substitutes and similar parts?

A: Direct substitutes (160MXG470MEFCSN22X25, LGN2C471MELZ25, EKMQ161VSN471MP25S) maintain identical case diameter (22.00 mm) and height (27.00 mm), ensuring drop-in compatibility. Similar parts (381LX series) have different mechanical dimensions and require PCB layout verification before use.

Q: Does the extended lifetime rating (3000 hours vs. 2000 hours) affect compatibility?

A: No. Extended lifetime is a performance benefit and does not affect electrical or mechanical compatibility. Parts with longer lifetime ratings are direct substitutes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What should I verify before selecting a substitute part?

A: Verify PCB layout constraints for case diameter and height. Confirm that the operating temperature range (-40°C to 105°C) meets application requirements. Validate that the voltage rating is equal to or higher than the original specification (minimum 160 V).

Q: Why is the original EET-HC2C471BA classified as obsolete?

A: Obsolescence reflects manufacturer discontinuation. Active substitute parts from Rubycon, Nichicon, Cornell Dubilier, and Chemi-Con provide equivalent or superior performance with ongoing supply availability.
