Engineering Selection Recommendations

Primary Substitute: EEU-HD1V331 (Panasonic Electronic Components)

The EEU-HD1V331 is the recommended substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is ROHS3 compliant and carries REACH Unaffected certification. The Panasonic HD series provides 1470 pieces in current inventory, supporting immediate procurement needs.

Secondary Substitute: UVY1V331MPD (Nichicon)

The UVY1V331MPD is a parametric equivalent with identical electrical and mechanical specifications. However, this part carries a "Not For New Designs" product status, indicating that Nichicon has discontinued active development for this model. While the part remains functionally equivalent and ROHS3 compliant, it is suitable only for legacy system maintenance, repair, and replacement applications where the original part number must be maintained. Nichicon UVY series inventory shows 2090 pieces available.

Both substitutes are electrically and mechanically interchangeable with the RJA331M1VBK-1012S and require no circuit modifications or PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can EEU-HD1V331 be used as a direct replacement for RJA331M1VBK-1012S?

A: Yes. The EEU-HD1V331 is a parametric equivalent with identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), ripple current (350 mA @ 120 Hz), and mechanical dimensions (10.00 mm diameter, 14.00 mm height, 5.00 mm lead spacing). No circuit modifications are required.

Q: What is the difference between the SURGE RJA and Panasonic HD series?

A: Both series are aluminum electrolytic capacitors with identical electrical and mechanical specifications for this 330 µF, 35 V rating. The primary differences are manufacturer, product status (both Active), and inventory availability. The Panasonic HD series is recommended for new designs due to active manufacturer support.

Q: Why is the Nichicon UVY1V331MPD marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Nichicon has transitioned this product line and is no longer actively developing or promoting it for new applications. The part remains functionally equivalent and available in inventory, but is intended for legacy system support and replacement applications only.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RJA331M1VBK-1012S, EEU-HD1V331, and UVY1V331MPD are all ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share identical lead spacing (5.00 mm), diameter (10.00 mm), height (14.00 mm), and through-hole mounting type. They are mechanically and electrically interchangeable without PCB modification.

Q: What is the ripple current rating for high-frequency applications?

A: The RJA331M1VBK-1012S specifies 350 mA @ 120 Hz (low frequency). The Panasonic EEU-HD1V331 provides additional high-frequency ripple current rating of 525 mA @ 100 kHz. The Nichicon UVY1V331MPD provides 525 mA @ 10 kHz. For applications requiring high-frequency ripple current performance, the Panasonic substitute offers superior specifications.

Q: Which substitute should be selected for long-term production?

A: The EEU-HD1V331 (Panasonic) is recommended for long-term production due to Active product status, established manufacturer support, and REACH compliance certification. This ensures consistent availability and compliance with evolving regulatory requirements.
