Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RXK331M1EBK-1016S is determined by the following critical parameters:

Electrical Parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 25 V (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing and physical dimensions must accommodate the same PCB footprint

Compliance Parameters:

• RoHS3 compliance required
• HTSUS classification: 8532.22.0020 (consistent across substitutes)

The UPM1E331MPD6 satisfies all substitution criteria through identical electrical specifications, equivalent mechanical form factor, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: UPM1E331MPD6 (Nichicon)

The UPM1E331MPD6 is the direct equivalent for the RXK331M1EBK-1016S. Both components share identical electrical specifications (330 µF, ±20%, 25 V) and mechanical form factors (radial, through-hole, can package). Both are RoHS3 compliant and classified under the same HTSUS code.

The UPM1E331MPD6 carries AEC-Q200 automotive qualification and is rated for 5000 hours at 105°C operating temperature. The component operates across the temperature range of -55°C to 105°C with specified ripple current ratings (630 mA @ 120 Hz, 825 mA @ 10 kHz) and impedance of 95 mOhms.

Product Status Consideration:

The UPM1E331MPD6 is designated as "Not For New Designs" by Nichicon. This status indicates the part is available for existing production and support but is not recommended for new circuit development. The RXK331M1EBK-1016S maintains Active status, making it the preferred choice for new designs. However, the UPM1E331MPD6 remains functionally equivalent for replacement and maintenance applications where the electrical and mechanical requirements are identical.

Frequently Asked Questions (FAQ)

Q: Can the UPM1E331MPD6 be used as a direct replacement for the RXK331M1EBK-1016S?

A: Yes. Both components have identical capacitance (330 µF), tolerance (±20%), voltage rating (25 V), and package type (radial, through-hole, can). The physical dimensions and lead spacing are compatible with the same PCB footprint. Both are RoHS3 compliant.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact matching of capacitance value, tolerance, voltage rating, polarization type, package configuration, and mounting method. Compliance certifications and HTSUS classification must also align. Dimensional compatibility with the PCB footprint is required.

Q: Why is the UPM1E331MPD6 marked as "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued active development and recommendation of this part for new circuit designs. However, the component remains available for production support and replacement applications. For new designs, the RXK331M1EBK-1016S (Active status) is the recommended choice.

Q: Are there any electrical performance differences between these parts?

A: Both components meet the same electrical specifications. The UPM1E331MPD6 provides additional performance data including ripple current ratings (630 mA @ 120 Hz, 825 mA @ 10 kHz), impedance (95 mOhms), and lifetime rating (5000 Hrs @ 105°C). These specifications confirm equivalent performance within the rated parameters.

Q: What compliance certifications apply to both parts?

A: Both the RXK331M1EBK-1016S and UPM1E331MPD6 are RoHS3 compliant. The UPM1E331MPD6 additionally carries AEC-Q200 automotive qualification. Both are classified under HTSUS code 8532.22.0020.

Q: Can these capacitors be used interchangeably in automotive applications?

A: The UPM1E331MPD6 is qualified to AEC-Q200 automotive standards. The RXK331M1EBK-1016S does not specify automotive qualification in the provided data. For automotive applications requiring AEC-Q200 certification, the UPM1E331MPD6 is the appropriate choice. For general-purpose applications, both components are functionally equivalent.

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

A: The UPM1E331MPD6 operates from -55°C to 105°C. The RXK331M1EBK-1016S does not specify an operating temperature range in the provided data. Both components are rated for 25 V at their respective operating conditions.
