UUR0J331MCL6GS Equivalent & Substitute Parts

Part Overview

The UUR0J331MCL6GS is a 330 µF, 6.3 V aluminum electrolytic capacitor manufactured by Nichicon in the UUR series. This surface mount component is rated for 2000 hours at 85°C and is classified as obsolete. Due to its obsolete status and limited inventory availability (2515 pcs), identifying qualified substitute parts is necessary for ongoing production and design continuity.

Engineering Selection Recommendations

For New Designs: UWT0J331MCL1GS (Nichicon) is the recommended primary substitute. This part is active, offers extended operating temperature range (-55°C ~ 105°C), and has substantial inventory availability (76716 pcs). The reduced height (0.303" vs 0.315") and improved thermal performance (1000 Hrs @ 105°C) provide design flexibility.

For Existing Designs with Footprint Constraints: EEE-0JA331XAP or EEE-0JA331XP (Panasonic) provide direct electrical and mechanical compatibility with the original UUR0J331MCL6GS. Both maintain identical capacitance, voltage, tolerance, and land size specifications. These parts carry AEC-Q200 automotive-grade certification and RoHS compliance, though they are classified as "Not For New Designs."

For Footprint Flexibility (8.00mm Diameter): UUR0J331MCL1GS (Nichicon), EEE-0JA331AP, or EEE-0JA331P (Panasonic) accommodate designs with larger land sizes (0.327" x 0.327"). These options provide higher ripple current ratings and greater inventory depth.

For Active Product Status: EDK337M6R3A9HAA (KEMET) is an active alternative with identical electrical specifications and compatible footprint. This part offers superior ripple current performance (280 mA @ 120 Hz, 350 mA @ 10 kHz) compared to the original.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. Panasonic parts (EEE series) include AEC-Q200 automotive certification. Nichicon UWT series provides extended temperature range support for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can UWT0J331MCL1GS replace UUR0J331MCL6GS in existing PCB layouts?

A: Yes, with minor considerations. Both parts share identical land size (0.260" x 0.260" / 6.60mm x 6.60mm) and diameter (0.248" / 6.30mm). The UWT variant is 0.012" (0.30mm) shorter in height, which is acceptable for most applications. Verify clearance in your specific layout.

Q: What is the difference between the 6.30mm and 8.00mm diameter options?

A: The 6.30mm diameter parts (UUR0J331MCL6GS, UWT0J331MCL1GS, EEE-0JA331XAP, EEE-0JA331XP, EMVA6R3ADA331MF80G, AVE337M06X16T-F, EDK337M6R3A9HAA) use 0.260" x 0.260" (6.60mm x 6.60mm) land sizes. The 8.00mm diameter parts (UUR0J331MCL1GS, EEE-0JA331AP, EEE-0JA331P) use 0.327" x 0.327" (8.30mm x 8.30mm) land sizes. Select based on your PCB footprint requirements.

Q: Are Panasonic EEE-0JA series parts suitable for new production?

A: Panasonic EEE-0JA331XAP, EEE-0JA331XP, EEE-0JA331AP, and EEE-0JA331P are classified as "Not For New Designs." These parts are suitable for legacy product support and existing design continuity but should not be selected for new development. Use UWT0J331MCL1GS or EDK337M6R3A9HAA for new designs.

Q: What is the inventory status for each substitute?

A: UWT0J331MCL1GS offers the highest availability (76716 pcs). UUR0J331MCL1GS provides 117400 pcs but is obsolete. EEE-0JA331P has 15121 pcs available. Other options range from 937 to 2886 pcs. Verify current stock with your distributor.

Q: Do all substitutes maintain the same ripple current ratings?

A: No. Ripple current varies by manufacturer and series. The original UUR0J331MCL6GS specifies 188 mA @ 120 Hz and 244.4 mA @ 10 kHz. EDK337M6R3A9HAA (KEMET) provides higher ripple current (280 mA @ 120 Hz, 350 mA @ 10 kHz). EEE-0JA331AP and EEE-0JA331P offer 300 mA @ 120 Hz and 510 mA @ 10 kHz. Confirm ripple current requirements for your application.

Q: What compliance certifications apply to these substitutes?

A: All parts are ROHS3 compliant and REACH unaffected. Panasonic EEE-0JA series parts include AEC-Q200 automotive-grade certification. Nichicon UUR and UWT series do not carry automotive certification. Select based on your application requirements.
