Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

Capacitance: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 350 V minimum (equal or higher acceptable)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Diameter: 1.181" (30.00 mm) (exact match required)
Height: 1.260" (32.00 mm) maximum (exact match required)
Mounting Type: Through Hole (exact match required)
Package: Radial, Can - Snap-In (exact match required)
Operating Temperature: -25°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Substitution Categories:

Direct Equivalents (350 V Rating): Parts maintaining the original 350 V voltage specification with identical physical dimensions and electrical characteristics.

Upgrade Substitutes (400 V, 420 V, 450 V Rating): Parts with higher voltage ratings that maintain all other physical and electrical parameters. Higher voltage ratings provide additional safety margin in applications where the original 350 V specification is met.

Engineering Selection Recommendations

Direct Equivalent Selection (350 V Category):

LGN2V331MELB30 and LQS2V331MELB30 from Nichicon provide direct electrical and mechanical equivalence to the EET-HC2V331DA. Both parts are active products with ROHS3 compliance and extended lifetime ratings of 3000 hours at 105°C compared to the original 2000-hour specification. These parts are suitable for direct replacement in existing designs without circuit modification.

Upgrade Substitute Selection (400 V and Higher):

Rubycon parts with 400 V, 420 V, and 450 V ratings maintain identical physical dimensions and capacitance values while providing higher voltage safety margins. These upgrades are applicable in circuits where the original 350 V specification is met and higher voltage tolerance is acceptable. All upgrade substitutes are active products with ROHS3 compliance.

The 400VXH330MEFC30X30 and 400VXH330MEFCSN30X30 offer the longest operational lifetime at 5000 hours at 105°C, suitable for applications requiring extended service life. The 400MXH330MEFCSN30X30 maintains the original 2000-hour lifetime specification while providing 400 V rating and is available in high inventory (1339 Pcs).

All substitute parts share identical lead spacing (10.00 mm), diameter (30.00 mm), height (32.00 mm), and through-hole mounting configuration with the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated capacitor in place of the 350 V EET-HC2V331DA?

A: Yes. Higher voltage-rated capacitors with identical capacitance, tolerance, physical dimensions, and mounting configuration are suitable substitutes. The 400 V, 420 V, and 450 V rated parts listed maintain all other specifications and provide additional voltage safety margin.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (LGN2V331MELB30, LQS2V331MELB30) maintain the original 350 V voltage rating. Upgrade substitutes feature higher voltage ratings (400 V, 420 V, 450 V) while preserving all physical dimensions and capacitance values. Both categories are mechanically and electrically compatible.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original EET-HC2V331DA is obsolete and does not carry RoHS certification.

Q: Does the snap-in package configuration differ between manufacturers?

A: No. All parts maintain identical radial, can snap-in package specifications with 0.394" (10.00 mm) lead spacing, 1.181" (30.00 mm) diameter, and 1.260" (32.00 mm) maximum seated height.

Q: Which substitute offers the longest operational lifetime?

A: The 400VXH330MEFC30X30 and 400VXH330MEFCSN30X30 from Rubycon provide 5000-hour lifetime at 105°C, compared to the original 2000-hour specification.

Q: Can I mix different substitute part manufacturers in the same circuit?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for capacitance, voltage, tolerance, dimensions, and mounting configuration. Mixing manufacturers is permissible from a compatibility standpoint.
