Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UUB1A331MNL1GS is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Surface Mount Land Size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Secondary Substitution Criteria (Allowable Variations):

• Lifetime @ 125°C: May vary (1000 Hrs minimum acceptable)
• Physical Dimensions (Diameter/Height): Minor variations acceptable within SMD can package standards
• ESR (Equivalent Series Resistance): May vary based on series design
• Ripple Current Ratings: May vary based on series design
• Manufacturer: Alternative manufacturers acceptable if all primary criteria met

Substitute parts are grouped into two categories:

Direct Substitutes (Same Manufacturer - Nichicon): Parts that maintain identical electrical specifications and package footprint while potentially offering different thermal or performance characteristics within the same product family.

Cross-Manufacturer Substitutes (Panasonic Electronic Components): Parts from alternative manufacturers that meet all primary substitution criteria and maintain full compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

Nichicon UWH1A331MCL1GS: Direct Nichicon substitute with identical package footprint and land size. Suitable for applications where thermal lifetime of 1000 hours at 125°C meets design requirements. Maintains ROHS3 compliance and MSL 1 rating.

Nichicon UCJ1A331MCL1GS: Nichicon alternative with 2000-hour thermal rating matching the original part. Height variation of 0.019" (0.50mm) requires PCB layout verification. Maintains full compliance and MSL 1 rating.

Panasonic EEE-TG1A331P: Cross-manufacturer substitute with identical 10.00mm diameter and matching land size. Rated for 2000 hours at 125°C. AEC-Q200 automotive qualification available. ROHS3 compliant with MSL 1 rating.

Panasonic EEE-TK1A331P: Extended thermal lifetime of 3000 hours at 125°C. Identical 10.00mm diameter and land size to original part. ROHS3 compliant with MSL 1 rating. Suitable for applications requiring enhanced thermal endurance.

Panasonic EEE-TP1A331AP: Extended thermal lifetime of 3000 hours at 125°C with AEC-Q200 automotive qualification. Identical 10.00mm diameter and land size. ROHS3 compliant with MSL 1 rating. Supports high temperature reflow applications.

Panasonic EEE-TG1A331UP and EEE-TK1A331UP: Smaller 8.00mm diameter variants with different land size (8.30mm x 8.30mm). These parts require PCB redesign and are not direct footprint substitutes. Suitable only when board layout permits smaller package accommodation.

Panasonic EEE-TPA331UAP: Smaller 8.00mm diameter variant with different land size (8.30mm x 8.30mm). Requires PCB redesign. Not a direct footprint substitute.

Frequently Asked Questions (FAQ)

Q: Can EEE-TG1A331UP be used as a direct replacement for UUB1A331MNL1GS?

A: No. While both parts share identical electrical specifications (330 µF, 10 V, ±20%), the EEE-TG1A331UP has a smaller 8.00mm diameter package with 8.30mm x 8.30mm land size, compared to the original 10.00mm diameter with 10.30mm x 10.30mm land size. PCB layout modification is required.

Q: What is the difference between UWH1A331MCL1GS and UUB1A331MNL1GS?

A: Both are Nichicon 330 µF, 10 V SMD aluminum electrolytic capacitors with identical package footprints. The primary difference is thermal lifetime: UWH1A331MCL1GS is rated for 1000 hours at 125°C, while UUB1A331MNL1GS is rated for 2000 hours at 125°C. Selection depends on application thermal requirements.

Q: Are Panasonic EEE-TK series parts suitable replacements?

A: Yes. Panasonic EEE-TK1A331P and EEE-TK1A331UP maintain identical electrical specifications and package footprints (for the 10.00mm diameter variant). The EEE-TK series offers extended thermal lifetime of 3000 hours at 125°C, providing enhanced reliability for demanding applications.

Q: What does AEC-Q200 qualification mean for automotive applications?

A: AEC-Q200 is an automotive electronics council qualification standard. Panasonic parts bearing this rating (EEE-TG1A331P, EEE-TP1A331AP, EEE-TPA331UAP) have undergone additional testing and validation for automotive use. These parts are suitable for automotive applications where such qualification is required.

Q: Can I use a part with higher thermal lifetime rating as a substitute?

A: Yes. Parts with higher thermal lifetime ratings (such as EEE-TK series at 3000 hours) are compatible substitutes for the original 2000-hour rated part. The higher rating provides equal or better performance and reliability.

Q: What packaging options are available?

A: The original UUB1A331MNL1GS is supplied in Tape & Reel (TR) packaging. Most substitute parts are also available in Tape & Reel format. EEE-TG1A331UP is supplied in Cut Tape (CT) & Digi-Reel format. Verify packaging requirements for your procurement and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity level, matching the original part's environmental and regulatory status.
