Engineering Selection Recommendations

Primary Selection: EEU-HD1V331 (Panasonic Electronic Components)

The EEU-HD1V331 is the preferred substitute for the RJA331M1VBK-1012S. Both parts are active products with identical electrical and mechanical specifications. The Panasonic component carries ROHS3 compliance and is suitable for new design implementations. Current inventory availability is 1470 units.

Secondary Selection: UVY1V331MPD (Nichicon)

The UVY1V331MPD meets all electrical and mechanical substitution criteria and carries ROHS3 compliance. However, this part is designated as "Not For New Designs," indicating it is in mature or end-of-life status. This component is suitable only for replacement, repair, or maintenance applications where the original part specification must be maintained. Current inventory availability is 2090 units.

Compliance Verification

All substitute parts maintain ROHS3 compliance and share the identical HTSUS classification (8532.22.0020), confirming regulatory and tariff equivalence with the original RJA331M1VBK-1012S.

Frequently Asked Questions (FAQ)

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

A: Yes. The EEU-HD1V331 is mechanically and electrically identical to the RJA331M1VBK-1012S. Both components share identical lead spacing (5.00 mm), diameter (10.00 mm), height (14.00 mm), and all electrical parameters. No PCB modifications are required.

Q: What is the difference between the two substitute parts?

A: Both EEU-HD1V331 and UVY1V331MPD meet identical electrical and mechanical specifications. The primary difference is product status: EEU-HD1V331 is an active product suitable for new designs, while UVY1V331MPD is designated "Not For New Designs," indicating mature or end-of-life status.

Q: Are there any ripple current differences between the main part and substitutes?

A: The main part number does not specify ripple current values. Both substitute parts provide ripple current ratings of 350 mA @ 120 Hz and 525 mA at high frequency (100 kHz for Panasonic, 10 kHz for Nichicon). These ratings ensure adequate performance in filtering and energy storage applications.

Q: Can UVY1V331MPD be used in new product designs?

A: No. The UVY1V331MPD is designated "Not For New Designs." This part is suitable only for replacement, repair, or maintenance of existing equipment. For new designs, use EEU-HD1V331 or the original RJA331M1VBK-1012S.

Q: Are all three parts RoHS compliant?

A: Yes. The RJA331M1VBK-1012S, EEU-HD1V331, and UVY1V331MPD are all ROHS3 compliant, confirming compliance with current environmental and regulatory standards.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across the identical temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C, ensuring consistent thermal performance across applications.
