EET-HC2W331LA Equivalent & Substitute Parts

Part Overview

The Panasonic EET-HC2W331LA is a 330 µF, 450 V aluminum electrolytic capacitor in radial, can snap-in package format, rated for general-purpose applications. This component features a 2000-hour lifetime at 105°C and operates across the temperature range of -25°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the EET-HC2W331LA is determined by strict equivalence across the following parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can - Snap-In (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Diameter: 1.378" (35.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Operating temperature range: -25°C ~ 105°C (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in lifetime rating (2000 Hrs to 5000 Hrs @ 105°C), ESR specifications, ripple current ratings, and compliance certifications do not disqualify parts from substitution, as these represent performance enhancements or different manufacturing standards rather than incompatibilities.

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications (330 µF, 450 V, ±20% tolerance) and mechanical compatibility (radial snap-in package, 10.00 mm lead spacing, 35.00 mm diameter, through-hole mounting). Selection among active alternatives depends on application-specific requirements:

For applications requiring exact height match to the original EET-HC2W331LA (1.457" / 37.00 mm), select from: 450HXG330MEFC35X35, 450VXG330MEFC35X35, 450VXG330MEFCSN35X35, B43508C5337M062, or B43508C5337M2.

For applications with space constraints permitting reduced height (1.260" / 32.00 mm or 1.063" / 27.00 mm), the Rubycon MXH, MXK, VXH, and VXK series provide compact alternatives while maintaining full electrical equivalence.

For applications subject to RoHS3 compliance requirements, exclude 450VXG330MEFC35X35 (RoHS non-compliant). All other active substitutes carry ROHS3 Compliant certification.

For applications requiring extended operational lifetime, Rubycon VXG, VXH, and VXK series (5000 Hrs @ 105°C) and Rubycon HXG series (3000 Hrs @ 105°C) exceed the original 2000-hour specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height rating?

A: Yes, provided the application PCB layout accommodates the dimensional change. The 450MXK330MEFC35X25 (1.063" height) and 450MXH330MEFCSN35X30 (1.260" height) are electrically equivalent to the EET-HC2W331LA (1.457" height) and maintain identical lead spacing and diameter. Verify clearance in your specific assembly before substitution.

Q: What is the difference between parts with and without "SN" in the part number?

A: The "SN" designation indicates a specific manufacturing variant or packaging specification. Both variants (with and without "SN") meet the same electrical and mechanical requirements for substitution. Consult the manufacturer datasheet for any process-specific differences if your application has specialized requirements.

Q: Are all substitute parts RoHS compliant?

A: Nine of the ten listed substitutes carry ROHS3 Compliant certification. The exception is 450VXG330MEFC35X35, which is RoHS non-compliant. For applications requiring RoHS3 compliance, select from the remaining nine alternatives.

Q: Does extended lifetime (5000 Hrs vs. 2000 Hrs) affect compatibility?

A: No. Extended lifetime represents improved performance and does not affect electrical or mechanical compatibility. Parts with 3000-hour or 5000-hour ratings are direct substitutes for the 2000-hour original specification.

Q: What is the significance of different ESR values?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance but does not determine substitutability. The original EET-HC2W331LA specifies 553 mOhm @ 120 Hz. Substitute parts with lower ESR values provide improved performance characteristics. Consult application requirements if ripple current or thermal dissipation are critical design parameters.

Q: Can I mix different substitute part numbers in the same assembly?

A: Yes, provided all selected parts meet the core electrical specifications (330 µF, 450 V, ±20% tolerance) and mechanical requirements (radial snap-in, 10.00 mm lead spacing, 35.00 mm diameter). Ensure height compatibility with your PCB layout if mixing parts with different seated heights.
