Key Parameters

Substitute Part Grouping Explanation

Substitution of the UHE1J331MHD is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)

The EEU-EB1J331 from Panasonic Electronic Components meets all these criteria and qualifies as a direct substitute. Physical dimensions and ripple current ratings may vary within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

The EEU-EB1J331 is the qualified substitute for the UHE1J331MHD based on electrical and mechanical parameter equivalence. The Panasonic part carries Active product status, ensuring continued availability and support for production applications. Both components are ROHS3 compliant and share identical electrical specifications for capacitance, voltage rating, tolerance, and thermal performance.

The primary physical difference is the seated height: the EEU-EB1J331 measures 0.866" (22.00 mm) compared to the UHE1J331MHD at 0.984" (25.00 mm). This 3 mm reduction in height must be evaluated against PCB layout constraints and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the EEU-EB1J331 be used as a direct replacement for the UHE1J331MHD?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lead spacing (5.00 mm), and package configuration (radial, through-hole). Electrical performance is equivalent across the specified operating range.

Q: What is the significance of the height difference between these parts?

A: The EEU-EB1J331 is 3 mm shorter in seated height (22.00 mm vs. 25.00 mm). This difference must be verified against PCB layout, component clearance, and mechanical assembly requirements before substitution.

Q: Why is the UHE1J331MHD marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. The EEU-EB1J331, with Active product status, is the recommended choice for new designs and ongoing production requiring this capacitance and voltage specification.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The UHE1J331MHD is REACH Affected, while the EEU-EB1J331 is REACH Unaffected. Compliance requirements should be verified against your application and regional regulations.

Q: Do ripple current ratings differ between these parts?

A: Yes. The EEU-EB1J331 has lower ripple current ratings (381 mA @ 120 Hz, 495.3 mA @ 100 kHz) compared to the UHE1J331MHD (612.5 mA @ 120 Hz, 875 mA @ 100 kHz). Applications requiring high ripple current handling must confirm the substitute meets thermal and performance requirements.
