Voltage Rating: 50 V (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Lifetime: 2000 Hrs @ 105°C (exact match required)

Mechanical Parameters:

Lead Spacing: 0.197" (5.00 mm) (exact match required)
Diameter: 0.394" (10.00 mm) (exact match required)
Height: 0.689" (17.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Engineering Selection Recommendations

Primary Recommendation: 50PX330MEFC10X16 (Rubycon)

The 50PX330MEFC10X16 is the preferred substitute for the RJA331M1HBK-1016S. This part maintains active product status and meets all electrical, mechanical, and compliance requirements. With 3828 units in stock, it provides reliable availability for production requirements.

Secondary Recommendation: EEU-HD1H331 (Panasonic Electronic Components)

The EEU-HD1H331 is an active product that satisfies all specified parameters. This part is suitable for new designs and offers 1400 units in current inventory. Panasonic's HD series provides established reliability in general-purpose applications.

Alternative Options: UVY1H331MPD and UVZ1H331MPD (Nichicon)

Both Nichicon parts—UVY1H331MPD and UVZ1H331MPD—meet all electrical and mechanical specifications. However, both are designated as "Not For New Designs," indicating obsolescence or discontinuation status. The UVZ1H331MPD offers significantly higher inventory availability (19237 units) and may be suitable for legacy system maintenance or existing design support. The UVY1H331MPD (2314 units) is available but carries the same product status restriction.

Compliance Assurance

All substitute parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across all major markets and applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RJA331M1HBK-1016S with any of the listed parts without circuit modification?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical capacitance (330 µF), voltage rating (50 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and physical dimensions (10.00 mm diameter, 17.50 mm height, 5.00 mm lead spacing). Direct substitution is possible without circuit redesign.

Q: What is the difference between active and "Not For New Designs" product status?

A: Active products are currently manufactured and recommended for new circuit designs. Parts marked "Not For New Designs" are in obsolescence or discontinuation phases. For new designs, select 50PX330MEFC10X16 or EEU-HD1H331. For legacy system support, Nichicon parts remain available.

Q: Are there differences in ripple current ratings between these parts?

A: Ripple current specifications are provided for some parts but not all. The 50PX330MEFC10X16 specifies 470 mA @ 120 Hz. The EEU-HD1H331 specifies 410 mA @ 120 Hz and 615 mA @ 100 kHz. The UVY1H331MPD specifies 410 mA @ 120 Hz and 615 mA @ 10 kHz. The UVZ1H331MPD specifies 410 mA @ 120 Hz. These variations do not affect interchangeability for general-purpose applications within the specified electrical parameters.

Q: Do all parts have the same moisture sensitivity level?

A: No. The EEU-HD1H331 specifies MSL 1 (Unlimited). The 50PX330MEFC10X16, UVY1H331MPD, and UVZ1H331MPD are listed as "Not Applicable." This difference does not affect substitution compatibility for through-hole radial components in standard PCB assembly environments.

Q: Which substitute offers the best inventory availability?

A: The UVZ1H331MPD (Nichicon) provides the highest inventory level with 19237 units in stock. However, this part carries "Not For New Designs" status. For active product status with strong availability, the 50PX330MEFC10X16 (Rubycon) offers 3828 units.

Q: Are all parts suitable for the same temperature range applications?

A: Yes. All substitute parts operate across the identical temperature range of -55°C ~ 105°C with a rated lifetime of 2000 hours at 105°C. They are suitable for equivalent thermal environments.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most global markets.
