Engineering Selection Recommendations

Direct Substitutes (Preferred):

LAR2D102MELZ50 and LGN2D102MELZ50 (Nichicon) are direct substitutes with identical lead spacing, case diameter, and snap-in package configuration. Both are active products with ROHS3 compliance. LGN2D102MELZ50 offers extended lifetime (3000 hours vs. 2000 hours at 105°C), providing improved reliability margin. LAR2D102MELZ50 maintains the original 2000-hour specification.

EKMQ201VSN102MP50S (Chemi-Con) matches the original dimensions exactly (22.00 mm diameter, 52.00 mm height) and maintains 2000-hour lifetime. ROHS3 compliance and active product status support long-term availability.

Similar Substitutes (Space-Dependent):

Cornell Dubilier 381LR and 381LX series parts meet all electrical specifications with extended 3000-hour lifetime at 105°C. These parts vary in case diameter and height:

381LR102M200J452 and 381LX102M200J052: 25.00 mm diameter, suitable for compact layouts
381LR102M200K032 and 381LX102M200K032: 30.00 mm diameter, moderate footprint
381LR102M200A022 and 381LX102M200A022: 35.00 mm diameter, larger footprint

All Cornell Dubilier parts feature ROHS3 compliance and active product status. The 381LR series specifies 149 mOhm ESR at 120 Hz, lower than the original 199 mOhm specification, improving thermal performance.

Selection Criteria:

Choose Nichicon or Chemi-Con substitutes when board space matches the original 22.00 mm diameter and 50-52 mm height. Select Cornell Dubilier parts when board layout permits larger case diameters and the extended 3000-hour lifetime provides system-level benefits. All recommended substitutes maintain through-hole mounting, 10.00 mm lead spacing, and snap-in package configuration.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different case diameter?

A: Yes, if board layout permits. All substitute parts maintain the same 10.00 mm lead spacing and snap-in package type. Verify that the larger case diameter (up to 35.00 mm) does not interfere with adjacent components or board routing. Height variation (32.00 mm to 52.00 mm) must also be confirmed against available vertical clearance.

Q: What is the difference between 381LR and 381LX series parts?

A: Both series meet identical electrical specifications (1000 µF, 200 V, ±20%, 3000 Hrs @ 105°C). The 381LR series specifies 149 mOhm ESR at 120 Hz, while 381LX series does not specify ESR. Both are suitable substitutes; selection depends on ESR performance requirements and available inventory.

Q: Are all substitute parts RoHS compliant?

A: Yes. Nichicon LAR and LGN series, Cornell Dubilier 381LR and 381LX series, and Chemi-Con EKMQ series are all ROHS3 compliant. The original EET-HC2D102BA is not RoHS compliant, making active substitutes advantageous for new designs and regulatory compliance.

Q: Can I substitute a part with lower lifetime rating?

A: No. The original EET-HC2D102BA specifies 2000 hours at 105°C. Substitute parts must meet or exceed this specification. Nichicon LAR2D102MELZ50 and Chemi-Con EKMQ201VSN102MP50S maintain 2000-hour rating. Nichicon LGN2D102MELZ50 and all Cornell Dubilier parts exceed this with 3000-hour rating.

Q: What is the impact of ESR differences?

A: Lower ESR improves thermal performance and reduces ripple current heating. Cornell Dubilier 381LR series specifies 149 mOhm ESR, lower than the original 199 mOhm, providing thermal margin. This is beneficial in high-ripple-current applications. Nichicon and Chemi-Con parts do not specify ESR but are electrically qualified for the application.

Q: Are snap-in packages interchangeable with solder-lead packages?

A: No. The EET-HC2D102BA uses snap-in package configuration for quick-connect terminals. All substitute parts listed maintain snap-in package type. Solder-lead or other package types are not compatible with the original mounting interface.

Q: Which substitute offers the best long-term availability?

A: Nichicon LGN2D102MELZ50 and Chemi-Con EKMQ201VSN102MP50S are active products with high inventory levels (839 and 1,000,400 units respectively), supporting long-term procurement. Cornell Dubilier 381LR and 381LX series also maintain active status with substantial inventory across multiple case diameter options.
