RJA331M1CBK-0811S Equivalent & Substitute Parts

Part Overview

The RJA331M1CBK-0811S is an aluminum electrolytic capacitor manufactured by SURGE, rated at 330 µF capacitance with 20% tolerance and 16 V nominal voltage. This component is designed for general-purpose applications requiring radial through-hole mounting in a can package format. The part maintains Active product status and is RoHS3 compliant.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when inventory levels require alternative sourcing, or when design flexibility permits selection from qualified equivalent components. The RJA331M1CBK-0811S has been identified with one parametric equivalent: the UPS1C331MPD from Nichicon.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJA331M1CBK-0811S is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Rated voltage: 16 V (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package configuration: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing and physical dimensions must accommodate existing PCB layouts

Compliance Parameters:

• RoHS3 compliance status (required for equivalent substitution)

The UPS1C331MPD from Nichicon satisfies all electrical and mechanical equivalence criteria. However, the Nichicon part carries a "Not For New Designs" product status, indicating it is suitable for replacement and maintenance applications only.

Engineering Selection Recommendations

Primary Selection (New Designs): The RJA331M1CBK-0811S from SURGE is the recommended choice for new circuit designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It is RoHS3 compliant and suitable for applications requiring 330 µF capacitance at 16 V with standard radial through-hole mounting.

Substitute Selection (Replacement & Maintenance): The UPS1C331MPD from Nichicon is a qualified parametric equivalent for replacement applications and field maintenance. This part meets all electrical and mechanical specifications and maintains RoHS3 compliance. The "Not For New Designs" designation indicates this part is appropriate for sustaining existing products and repair scenarios where the original component is unavailable.

Both parts are suitable for general-purpose applications and share identical electrical ratings, physical dimensions, and compliance certifications. Selection between these parts should be based on availability, supply chain requirements, and design phase (new development versus maintenance).

Frequently Asked Questions (FAQ)

Q: Can the UPS1C331MPD be used as a direct replacement for the RJA331M1CBK-0811S?

A: Yes, the UPS1C331MPD is a parametric equivalent with identical capacitance (330 µF), tolerance (±20%), voltage rating (16 V), and physical dimensions. Both parts use radial through-hole mounting in a can package and are RoHS3 compliant. Direct PCB substitution is supported without layout modifications.

Q: What does "Not For New Designs" mean for the UPS1C331MPD?

A: This product status designation indicates the Nichicon UPS1C331MPD is intended for replacement and maintenance applications only. New circuit designs should specify the RJA331M1CBK-0811S or other Active-status equivalents. The "Not For New Designs" status does not affect functional performance or reliability in existing applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the RJA331M1CBK-0811S and UPS1C331MPD share identical physical specifications: 0.315" diameter (8.00mm), 0.512" maximum seated height (13.00mm), and 0.138" lead spacing (3.50mm). These parts are mechanically interchangeable on standard PCB layouts.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RJA331M1CBK-0811S and UPS1C331MPD are RoHS3 compliant. Both parts carry the same HTSUS classification (8532.22.0020), confirming regulatory equivalence for applications requiring RoHS compliance.

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

A: Both parts operate across the temperature range of -55°C to 105°C. This range supports general-purpose applications in industrial and commercial environments.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. The UPS1C331MPD can replace the RJA331M1CBK-0811S in existing assemblies without functional impact. Identical electrical ratings, physical dimensions, and mounting configurations ensure compatibility. No PCB modifications or design changes are required.
