Substitute Part Grouping Explanation

Substitution for the EET-HC2C122KA is determined by strict equivalence across the following parameters: capacitance (1200 µF), voltage rating (160 V), tolerance (±20%), package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (10.00 mm). Parts are grouped into four categories based on their relationship to the main part:

Direct Manufacturer Equivalent: Parts meeting all electrical and mechanical parameters with active product status and extended lifetime ratings.

Upgrade Equivalent: Parts with identical core specifications but enhanced performance characteristics (extended lifetime, improved ripple current handling) and active availability.

Similar Equivalent: Parts matching all core parameters but with dimensional variations in can diameter and height, maintaining functional compatibility within the snap-in package family.

Parametric Equivalent: Parts with identical electrical specifications and physical footprint, differing only in manufacturing series designation.

Engineering Selection Recommendations

For applications requiring direct replacement with identical physical footprint and electrical performance, LGG2C122MELB30 (Nichicon) and 381LQ122M160K022 (Cornell Dubilier Electronics) provide active product status with matching can diameter (30.00 mm) and height (32.00 mm).

For applications where extended component lifetime is beneficial, LGN2C122MELB30 (Nichicon) and 160MXG1200MEFCSN30X30 (Rubycon) offer 3000-hour lifetime ratings at 105°C while maintaining identical physical dimensions and electrical specifications. Both parts carry RoHS3 compliance and REACH unaffected status.

For applications with space constraints or where can diameter variation is acceptable, 381LQ122M160H452 and 381LX122M160J452 (Cornell Dubilier Electronics) provide alternative physical configurations with smaller or intermediate can diameters while maintaining the 10.00 mm lead spacing and snap-in mounting interface. The 381LX122M160J452 variant offers extended 3000-hour lifetime.

All substitute parts maintain the required 1200 µF capacitance, 160 V voltage rating, ±20% tolerance, and through-hole snap-in package compatibility with the original EET-HC2C122KA specification.

Frequently Asked Questions (FAQ)

Q: Can LGN2C122MELB30 be used as a direct replacement for EET-HC2C122KA?

A: Yes. LGN2C122MELB30 matches all critical parameters: 1200 µF capacitance, 160 V rating, ±20% tolerance, identical can diameter (30.00 mm), height (32.00 mm), and 10.00 mm lead spacing. The part is active and offers extended 3000-hour lifetime at 105°C compared to the original 2000-hour rating.

Q: What is the difference between the Nichicon and Cornell Dubilier options?

A: Nichicon parts (LGN2C122MELB30, LGG2C122MELB30) maintain the original 30.00 mm can diameter and 32.00 mm height. Cornell Dubilier 381LQ and 381LX series offer alternative can diameters (22.00 mm and 25.00 mm respectively) with increased height (47.00 mm), providing flexibility for different PCB layout constraints while preserving electrical equivalence.

Q: Are there compliance differences between substitute parts?

A: LGN2C122MELB30, 160MXG1200MEFCSN30X30, and all Cornell Dubilier parts carry RoHS3 compliance and REACH unaffected status. The original EET-HC2C122KA is REACH affected. All parts are classified as EAR99 for export control purposes.

Q: Does the 10.00 mm lead spacing remain consistent across all substitutes?

A: Yes. All substitute parts maintain 0.394" (10.00 mm) lead spacing, ensuring compatibility with existing PCB snap-in mounting interfaces designed for the EET-HC2C122KA.

Q: Which substitute offers the best performance upgrade?

A: 160MXG1200MEFCSN30X30 (Rubycon) and LGN2C122MELB30 (Nichicon) both provide 3000-hour lifetime ratings at 105°C with identical physical dimensions to the original part, representing the most direct performance enhancement while maintaining form-factor compatibility.
