Substitute Part Grouping Explanation

Substitution eligibility for the UCZ1J100MCS1GS is determined by strict equivalence across the following critical parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 2 Ohm @ 100 kHz (exact match required)
• Lifetime: 2000 Hrs @ 125°C (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Polarization: Polar (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The UCZ1J100MCL1GS meets all substitution criteria and is classified as a direct equivalent within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

Both the UCZ1J100MCS1GS and UCZ1J100MCL1GS are classified as "Not For New Designs" within the Nichicon UCZ series. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and deployment.

The primary distinction between these parts is the seated height specification: the UCZ1J100MCS1GS has a maximum seated height of 0.315" (8.00 mm), while the UCZ1J100MCL1GS has a maximum seated height of 0.323" (8.20 mm). This 0.008" (0.20 mm) difference is negligible for most applications and does not affect electrical performance or functional compatibility.

Selection between these equivalents should be based on PCB layout constraints and available inventory. Both parts deliver identical electrical performance across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can UCZ1J100MCL1GS replace UCZ1J100MCS1GS in existing designs?

A: Yes. Both parts are electrically equivalent with identical capacitance, voltage rating, ESR, lifetime rating, and ripple current specifications. The 0.20 mm height difference is within typical PCB design tolerances and does not affect circuit performance.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and ECCN/HTSUS classifications.

Q: What does "Not For New Designs" mean?

A: This product status indicates that while the part remains available in inventory, Nichicon recommends evaluating alternative components for new development projects. Existing designs using these parts may continue without modification.

Q: Are the land sizes identical?

A: Yes. Both parts specify identical surface mount land sizes of 0.260" L x 0.260" W (6.60 mm x 6.60 mm), ensuring PCB footprint compatibility.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
