Substitute Part Grouping Explanation

Substitution of the UCZ1A331MCS6GS is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR specification: 200 mOhm @ 100 kHz (exact match required)
• Lifetime rating: 3000 Hrs @ 125°C (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.315" Dia (8.00 mm) × 0.425" H (10.80 mm) (exact match required)
• Surface mount land size: 0.327" L × 0.327" W (8.30 mm × 8.30 mm) (exact match required)
• RoHS3 compliance (required for new designs)

The substitute parts listed below meet all these criteria and are sourced from active product lines with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts, EEE-TC1A331UV and EEE-TPA331UAV from Panasonic Electronic Components, are direct electrical and mechanical equivalents to the UCZ1A331MCS6GS. The primary distinction between the original part and substitutes is product status: the UCZ series is classified as Not For New Designs, while both Panasonic alternatives are Active products with current manufacturing support.

For new design implementations, either Panasonic substitute is appropriate. Both parts carry AEC-Q200 automotive qualification and are rated for automotive and high-temperature reflow applications, providing enhanced reliability assurance compared to the original Nichicon part. The Panasonic substitutes maintain identical electrical performance, physical footprint, and compliance certifications (ROHS3, REACH Unaffected).

For legacy system maintenance or continued production of existing designs using the UCZ1A331MCS6GS, either substitute provides drop-in compatibility without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can EEE-TC1A331UV and EEE-TPA331UAV be used interchangeably with UCZ1A331MCS6GS?

A: Yes. Both Panasonic parts are electrically and mechanically equivalent. They share identical capacitance (330 µF), voltage rating (10 V), tolerance (±20%), ESR (200 mOhm @ 100 kHz), lifetime rating (3000 Hrs @ 125°C), operating temperature range (-40°C ~ 125°C), and physical dimensions (0.315" Dia × 0.425" H with 0.327" × 0.327" land size). No circuit or PCB modifications are required.

Q: What is the difference between EEE-TC1A331UV and EEE-TPA331UAV?

A: Both parts are functionally equivalent for the specified electrical parameters. The primary differences are manufacturer series designation (TCU vs. TP) and ripple current ratings at specific frequencies. EEE-TC1A331UV provides 266.5 mA @ 120 Hz and 410 mA @ 100 kHz, while EEE-TPA331UAV provides 175.5 mA @ 120 Hz and 270 mA @ 100 kHz. Selection depends on application ripple current requirements.

Q: Why is the original UCZ1A331MCS6GS marked as Not For New Designs?

A: This designation indicates the part has been superseded in Nichicon's active product portfolio. Panasonic equivalents are recommended for new designs to ensure long-term supply continuity and access to current manufacturing support.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both EEE-TC1A331UV and EEE-TPA331UAV are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original UCZ1A331MCS6GS.

Q: Do the substitute parts have automotive qualification?

A: Yes. Both Panasonic substitutes carry AEC-Q200 rating and are specified for automotive and high-temperature reflow applications, providing enhanced qualification compared to the original part.

Q: Will the substitute parts fit the existing PCB layout?

A: Yes. All three parts share identical physical dimensions (0.315" Dia × 0.425" H) and surface mount land size (0.327" L × 0.327" W), ensuring direct PCB compatibility without layout modification.
