RJA331M1HBK-1016S Equivalent & Substitute Parts

Part Overview

The RJA331M1HBK-1016S is a 330 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by SURGE. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with 714 units in stock.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RJA331M1HBK-1016S is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 2000 Hrs @ 105°C (exact match required)
Operating Temperature: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Critical Mechanical Parameters:

Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Height (Seated Max): 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 Selection (Active Status):

The 50PX330MEFC10X16 (Rubycon PX series) and EEU-HD1H331 (Panasonic HD series) are both active production parts with full design-in status. Both meet all electrical and mechanical specifications identical to the RJA331M1HBK-1016S. The Rubycon part offers higher ripple current capacity at 470 mA @ 120 Hz compared to 410 mA @ 120 Hz for the primary part. The Panasonic part provides additional ripple current specification at high frequency (615 mA @ 100 kHz) and carries MSL rating of 1 (Unlimited). Both parts carry ROHS3 compliance and REACH Unaffected status.

Secondary Selection (Not For New Designs):

The UVY1H331MPD (Nichicon UVY series) and UVZ1H331MPD (Nichicon UVZ series) are marked as "Not For New Designs" and should be used only for replacement or legacy system support. The UVZ1H331MPD maintains the highest inventory availability at 19,237 units. Both Nichicon parts meet all specified electrical and mechanical parameters and carry ROHS3 compliance and REACH Unaffected status.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and are suitable for applications requiring RoHS-compliant components. The Panasonic EEU-HD1H331 specifies MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 50PX330MEFC10X16 be used as a direct replacement for RJA331M1HBK-1016S?

A: Yes. The 50PX330MEFC10X16 meets all critical electrical and mechanical specifications: 330 µF capacitance, 50 V voltage rating, ±20% tolerance, 2000 Hrs @ 105°C lifetime, -55°C to 105°C operating range, 0.197" lead spacing, 0.394" case diameter, 0.689" maximum height, through-hole radial can package, and ROHS3 compliance. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the Nichicon UVY1H331MPD and UVZ1H331MPD?

A: Both parts are electrically and mechanically identical in all specified parameters. The primary difference is product status: UVY1H331MPD is marked "Not For New Designs," while UVZ1H331MPD carries the same status. Both meet the RJA331M1HBK-1016S specifications. The UVZ1H331MPD has significantly higher inventory availability (19,237 units versus 2,314 units).

Q: Are there any ripple current differences that affect substitution?

A: Ripple current ratings vary among the substitute parts. The RJA331M1HBK-1016S and EEU-HD1H331 specify 410 mA @ 120 Hz, while the 50PX330MEFC10X16 specifies 470 mA @ 120 Hz. The EEU-HD1H331 additionally specifies 615 mA @ 100 kHz. These variations do not disqualify substitution when all primary electrical and mechanical specifications are identical. Ripple current capacity is a performance characteristic that may exceed application requirements.

Q: Can I use the Panasonic EEU-HD1H331 in moisture-sensitive applications?

A: The EEU-HD1H331 carries MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. This part can be used in applications with extended storage periods or high-humidity environments without special moisture control measures.

Q: Why are some substitute parts marked "Not For New Designs"?

A: The Nichicon UVY1H331MPD and UVZ1H331MPD are marked "Not For New Designs," indicating these are legacy or end-of-life series. These parts remain suitable for replacement applications and legacy system support but should not be selected for new product designs when active alternatives are available.

Q: Do all substitute parts have identical physical dimensions?

A: Yes. All substitute parts share identical mechanical specifications: 0.197" (5.00 mm) lead spacing, 0.394" (10.00 mm) case diameter, and 0.689" (17.50 mm) maximum seated height. All are through-hole radial can packages suitable for identical PCB footprints.

Q: Which substitute part has the best inventory availability?

A: The UVZ1H331MPD (Nichicon) has the highest inventory at 19,237 units. The 50PX330MEFC10X16 (Rubycon) has 3,828 units, and the EEU-HD1H331 (Panasonic) has 1,400 units available.
