RXK331M1VBK-1020S Equivalent & Substitute Parts

Part Overview

The RXK331M1VBK-1020S is an aluminum electrolytic capacitor manufactured by SURGE with a capacitance of 330 µF, rated voltage of 35 V, and tolerance of ±20%. This radial, through-hole component is designed for general-purpose applications requiring stable capacitance performance across industrial temperature ranges. The part is currently Active in product status and fully compliant with ROHS3 standards.

Equivalent and substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design flexibility permits the use of alternative manufacturers' components that meet identical electrical and mechanical specifications. The substitute parts listed maintain full compatibility with the original RXK331M1VBK-1020S across all critical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the RXK331M1VBK-1020S is determined by strict equivalence across the following parameters:

• Capacitance Value: 330 µF (exact match required)
• Rated Voltage: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Configuration: Through Hole (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Can Diameter: 0.394" (10.00 mm) (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The substitute parts UPJ1V331MPD and UPM1V331MPD meet all mandatory electrical and mechanical parameters. Both components are manufactured by Nichicon and provide direct functional equivalence to the RXK331M1VBK-1020S.

Engineering Selection Recommendations

RXK331M1VBK-1020S (Primary Component)

The RXK331M1VBK-1020S maintains Active product status and is the preferred selection for new designs and ongoing production. This component is manufactured by SURGE and carries full ROHS3 compliance with ECCN classification 3A001.

UPJ1V331MPD (Nichicon - General Purpose Applications)

The UPJ1V331MPD is classified as Not For New Designs but remains available for legacy system support and replacement applications. This component is suitable for general-purpose applications and carries ROHS3 compliance with EAR99 ECCN classification. The UPJ1V331MPD exhibits an impedance of 96 mOhms and is not subject to REACH restrictions.

UPM1V331MPD (Nichicon - Automotive Applications)

The UPM1V331MPD is classified as Not For New Designs but is qualified for automotive applications under AEC-Q200 standards. This component features a lower impedance of 60 mOhms compared to the UPJ1V331MPD and carries ROHS3 compliance with EAR99 ECCN classification. The UPM1V331MPD is subject to REACH regulations. The automotive qualification and lower impedance characteristics make this component suitable for automotive circuit applications requiring enhanced performance specifications.

Both Nichicon substitutes provide electrical and mechanical equivalence to the RXK331M1VBK-1020S. Selection between UPJ1V331MPD and UPM1V331MPD depends on application requirements: general-purpose circuits favor the UPJ1V331MPD, while automotive applications benefit from the AEC-Q200 qualification and improved impedance characteristics of the UPM1V331MPD.

Frequently Asked Questions (FAQ)

Q: Can UPJ1V331MPD and UPM1V331MPD be used interchangeably with RXK331M1VBK-1020S?

A: Both Nichicon components meet all mandatory electrical and mechanical specifications of the RXK331M1VBK-1020S, including capacitance, voltage rating, tolerance, package type, mounting configuration, and lead spacing. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between UPJ1V331MPD and UPM1V331MPD?

A: Both components share identical capacitance, voltage, tolerance, and physical dimensions. The primary differences are: UPM1V331MPD carries AEC-Q200 automotive qualification and exhibits lower impedance (60 mOhms versus 96 mOhms). UPM1V331MPD is subject to REACH regulations, while UPJ1V331MPD is not. Height specifications differ slightly (0.866" for UPM1V331MPD versus 0.846" for UPJ1V331MPD).

Q: Are there height clearance concerns when substituting these parts?

A: The UPM1V331MPD has a maximum seated height of 0.866" (22.00 mm), while the UPJ1V331MPD has a maximum seated height of 0.846" (21.50 mm). Both heights are within typical PCB clearance tolerances for radial through-hole capacitors. Verify specific board layout constraints before final component selection.

Q: Do these substitute parts maintain the same lead spacing?

A: All three components maintain identical lead spacing of 0.197" (5.00 mm) and can diameter of 0.394" (10.00 mm). PCB footprints designed for the RXK331M1VBK-1020S accommodate both Nichicon substitutes without modification.

Q: What is the significance of the "Not For New Designs" status on the Nichicon parts?

A: This designation indicates that Nichicon recommends these components for legacy system support and replacement applications only. For new product development, the active RXK331M1VBK-1020S is the preferred selection. However, the Nichicon components remain fully functional and available for existing designs requiring component replacement.

Q: Are all three components RoHS3 compliant?

A: All three components carry ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.
