EKRG350ELL331MJC5S Equivalent & Substitute Parts

Part Overview

The EKRG350ELL331MJC5S is a 330 µF, 35 V aluminum electrolytic capacitor manufactured by Chemi-Con in the KRG series. This radial, through-hole component is rated for 1000 hours at 105°C and is designed for general-purpose applications. The part is currently active in production with 798 units in stock.

Substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, or when alternative manufacturers' components offer equivalent electrical and mechanical performance within the specified parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the EKRG350ELL331MJC5S is determined by the following criteria:

Primary Electrical Parameters (Must Match):

Capacitance: 330 µF
Voltage Rating: 35 V
Tolerance: ±20%
Polarization: Polar

Mechanical Parameters (Must Match):

Lead Spacing: 5.00 mm (0.197")
Diameter: 10.00 mm (0.394")
Height - Seated (Max): 14.00 mm (0.551") or equivalent
Mounting Type: Through Hole
Package / Case: Radial, Can

Operating Parameters (Must Match or Exceed):

Operating Temperature Range: -55°C ~ 105°C
Lifetime @ 105°C: 1000 hours minimum

All substitute parts listed meet these criteria. Parts with extended lifetime ratings (2000 hours @ 105°C) are acceptable as they exceed the minimum requirement and provide enhanced reliability.

Engineering Selection Recommendations

For Active Production Designs:

ECA-1VHG331 (Panasonic NHG-A series) and EEU-HD1V331 (Panasonic HD series) are recommended as primary substitutes. Both parts are marked as Active in product status, ensuring long-term availability and continued manufacturer support. Both offer extended lifetime ratings of 2000 hours at 105°C, exceeding the original part's 1000-hour specification. ECA-1VHG331 has a slightly reduced seated height of 13.50 mm compared to the original 14.00 mm, which may provide marginal PCB layout advantages. EEU-HD1V331 maintains the original 14.00 mm height specification.

For Legacy or Maintenance Applications:

UVY1V331MPD (Nichicon UVY series) and UKA1V331MPD (Nichicon UKA series) are available as alternatives. Both parts are marked as "Not For New Designs," indicating they are suitable for replacement in existing equipment or legacy systems but should not be selected for new product development. Both provide 2000-hour lifetime ratings at 105°C. UKA1V331MPD is specified for audio applications.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original EKRG350ELL331MJC5S is RoHS compliant (earlier standard). All parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Frequently Asked Questions (FAQ)

Q: Can ECA-1VHG331 be used as a direct replacement for EKRG350ELL331MJC5S?

A: Yes. Both parts have identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), and diameter (10.00 mm). ECA-1VHG331 has a seated height of 13.50 mm versus the original 14.00 mm, which is acceptable for through-hole mounting. The extended 2000-hour lifetime at 105°C exceeds the original specification.

Q: What is the difference between EEU-HD1V331 and ECA-1VHG331?

A: Both are Panasonic products with identical electrical specifications and 2000-hour lifetime ratings. The primary difference is the seated height: ECA-1VHG331 is 13.50 mm while EEU-HD1V331 is 14.00 mm. EEU-HD1V331 matches the original part's height exactly. Selection depends on PCB layout constraints.

Q: Why are UVY1V331MPD and UKA1V331MPD marked as "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued these series for new product development. These parts remain available for replacement in existing equipment and legacy systems. For new designs, Panasonic alternatives (ECA-1VHG331 or EEU-HD1V331) are preferred.

Q: Are all substitute parts through-hole mounted with radial leads?

A: Yes. All substitute parts are through-hole mounted with radial leads in a can package, maintaining identical mounting compatibility with the original EKRG350ELL331MJC5S.

Q: Do the substitute parts have the same ripple current ratings?

A: The Panasonic parts (ECA-1VHG331 and EEU-HD1V331) and Nichicon UVY1V331MPD specify 350 mA @ 120 Hz and 525 mA @ 100 kHz, which are slightly higher than the original part's 340 mA @ 120 Hz and 510 mA @ 100 kHz. UKA1V331MPD specifies 350 mA @ 120 Hz with no high-frequency ripple current specification provided.

Q: What is the inventory status of substitute parts?

A: ECA-1VHG331 has 22,199 units in stock, EEU-HD1V331 has 1,470 units, UVY1V331MPD has 2,090 units, and UKA1V331MPD has 2,292 units. The original EKRG350ELL331MJC5S has 798 units available.
