UCM1C331MCL1GS Equivalent & Substitute Parts

Part Overview

The UCM1C331MCL1GS is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Nichicon in surface mount radial can package. This component is designed for automotive applications with AEC-Q200 qualification and operates across -55°C to 105°C with a rated lifetime of 2000 hours at 105°C. The part is actively produced and ROHS3 compliant, making it suitable for modern automotive and industrial electronics requiring stable capacitance performance in demanding thermal environments.

Equivalent substitute parts are identified when they maintain identical or superior electrical characteristics, matching mechanical compatibility, and equivalent or better reliability ratings. Substitute identification ensures design continuity and supply chain flexibility without compromising performance or safety requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the UCM1C331MCL1GS is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Surface mount land size: 0.260" L x 0.260" W (6.60mm x 6.60mm) (exact match required)
• Operating temperature range: -55°C to 105°C (minimum requirement)
• Lifetime rating: 2000 Hrs @ 105°C (minimum requirement)
• Polarization: Polar (exact match required)
• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory alignment)

The EEE-FTC331XAP manufactured by Panasonic Electronic Components meets all substitution criteria and is classified as an equivalent part for the UCM1C331MCL1GS.

Parameter Comparison

Engineering Selection Recommendations

Both the UCM1C331MCL1GS and EEE-FTC331XAP are active production parts with identical electrical specifications and equivalent mechanical compatibility. Selection between these parts may be based on:

• Supply chain availability and lead time requirements
• Inventory status and procurement cost
• Manufacturer preference or qualification requirements
• PCB assembly process compatibility with either manufacturer's specifications

Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for automotive and industrial applications. The maximum height difference of 0.004" (0.10mm) between the two parts is within typical PCB assembly tolerances and does not affect functional performance or mechanical fit on standard surface mount land patterns.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FTC331XAP be used as a direct replacement for the UCM1C331MCL1GS?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, operating temperature range, lifetime rating, and surface mount land size. The maximum height difference of 0.004" (0.10mm) is within standard PCB assembly tolerances and does not affect compatibility.

Q: Are there any electrical performance differences between these parts?

A: Both parts meet the same ripple current specifications at 100 kHz (600 mA) and operate across the same temperature range with equivalent lifetime ratings. The ESR specifications are equivalent at 160 mOhms @ 100 kHz.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the UCM1C331MCL1GS and EEE-FTC331XAP carry AEC-Q200 qualification, confirming suitability for automotive applications.

Q: Are there any RoHS or regulatory compliance differences?

A: Both parts are ROHS3 compliant. The UCM1C331MCL1GS is REACH Affected, while the EEE-FTC331XAP is REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical surface mount land sizes (0.260" L x 0.260" W) and matching mechanical dimensions ensure direct PCB compatibility without design modifications.
