Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCZ1J330MCS6GS is determined by the following critical parameters:

Direct Equivalents maintain identical electrical specifications: 33 µF capacitance, 63 V voltage rating, ±20% tolerance, 700 mOhm ESR, 3000 hour lifetime at 125°C, and identical physical footprint (8.00 mm diameter, 8.30 mm × 8.30 mm land size). The only permitted variation is seated height, which may differ within the SMD radial can package envelope without affecting PCB assembly compatibility.

Upgrade Alternatives provide enhanced voltage rating (80 V instead of 63 V) while maintaining identical capacitance, tolerance, temperature range, and physical footprint. Higher voltage rating allows operation in circuits with greater voltage margins. ESR and ripple current specifications may vary slightly due to different internal construction.

All substitute parts must be Nichicon UCZ series components with ROHS3 compliance and MSL 1 rating to ensure manufacturing process compatibility and moisture sensitivity alignment.

Parameter Comparison

Engineering Selection Recommendations

UCZ1J330MCL6GS serves as the direct equivalent replacement. This part maintains all electrical and mechanical specifications of the original component. Selection of this substitute is appropriate when exact parameter matching is required and circuit voltage margins are already established at 63 V operation.

UCZ1K330MCS6GS functions as an upgrade alternative with 80 V voltage rating. This part is suitable for applications where increased voltage headroom provides design margin benefits. The 50 mOhm increase in ESR and reduced ripple current ratings must be evaluated against specific circuit requirements. Physical footprint compatibility is maintained, enabling direct PCB substitution.

All three parts carry identical ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard surface mount assembly processes and moisture-sensitive device handling protocols.

Frequently Asked Questions (FAQ)

Q: Can UCZ1J330MCL6GS replace UCZ1J330MCS6GS in existing designs?

A: Yes. UCZ1J330MCL6GS is a direct equivalent with identical electrical specifications and physical footprint. The only difference is seated height (10.50 mm vs. 10.80 mm), which remains within the SMD radial can package envelope and does not affect PCB assembly compatibility.

Q: What is the primary advantage of using UCZ1K330MCS6GS?

A: UCZ1K330MCS6GS provides 80 V voltage rating compared to 63 V in the original part. This higher rating allows operation in circuits with greater voltage stress or transient conditions. The part maintains identical capacitance, tolerance, and physical footprint.

Q: Are there any electrical performance differences between the direct equivalent and upgrade?

A: Yes. UCZ1K330MCS6GS has 750 mOhm ESR (vs. 700 mOhm) and lower ripple current ratings: 35 mA @ 120 Hz and 70 mA @ 100 kHz (vs. 50 mA and 100 mA respectively). These differences must be evaluated against circuit ripple current requirements.

Q: Do all substitute parts have identical physical dimensions?

A: Physical diameter (8.00 mm) and land size (8.30 mm × 8.30 mm) are identical across all parts. Seated height varies
