Substitute Part Grouping Explanation

Substitution of the UVR2F330MHD is determined by the following criteria:

Electrical Compatibility:

Capacitance value must be 33 µF
Tolerance must be ±20%
Voltage rating must be equal to or greater than 315 V
Operating temperature range must accommodate -40°C ~ 85°C minimum

Mechanical Compatibility:

Lead spacing must be 0.295" (7.50mm)
Case diameter must be 0.630" (16.00mm)
Height must not exceed 1.063" (27.00mm) for standard PCB clearance
Mounting type must be Through Hole

Engineering Selection Recommendations

Primary Recommendation - Active Status Parts:

For new applications and ongoing production support, select from parts with Active product status:

UAQ2G330MHD6 (Nichicon, 400 V, Active)
400PX33MEFC16X25 (Rubycon, 400 V, Active)
EKMG351ELL330ML25S (Chemi-Con, 350 V, Active)
EKMG401ELL330ML25S (Chemi-Con, 400 V, Active)
EKMQ401ELL330ML25S (Chemi-Con, 400 V, Active)
EKXF451ELL330ML25S (Chemi-Con, 450 V, Active)
ESMG351ELL330ML25S (Chemi-Con, 350 V, Active)
ESMG401ELL330ML25S (Chemi-Con, 400 V, Active)

Voltage Selection Criteria:

350 V rated parts (UVR2V330MHD, EKMG351ELL330ML25S, ESMG351ELL330ML25S) provide minimal voltage margin above the original 315 V specification and are suitable for direct replacement in legacy applications.

400 V rated parts (UAQ2G330MHD6, 400PX33MEFC16X25, EKMG401ELL330ML25S, EKMQ401ELL330ML25S, ESMG401ELL330ML25S) offer increased design margin and are recommended for applications requiring enhanced reliability.

450 V rated parts (ULD2W330MHD, EKXF451ELL330ML25S) provide maximum voltage margin and extended lifetime ratings (20000 Hrs @ 105°C), suitable for demanding applications requiring long-term stability.

Temperature Performance:

Parts rated for 105°C operation (UAQ2G330MHD6, EKMG351ELL330ML25S, EKMG401ELL330ML25S, EKMQ401ELL330ML25S, EKXF451ELL330ML25S) exceed the original -40°C ~ 85°C range and provide superior thermal performance.

Parts rated for 85°C operation (ESMG351ELL330ML25S, ESMG401ELL330ML25S) match the original thermal specification.

Compliance:

All substitute parts maintain ROHS3 compliance and are suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 350 V rated capacitor in place of the UVR2F330MHD (315 V)?

A: Yes. The 350 V rating exceeds the original 315 V specification, providing adequate voltage margin. Parts such as UVR2V330MHD, EKMG351ELL330ML25S, and ESMG351ELL330ML25S are electrically compatible direct replacements.

Q: What is the advantage of using a 400 V or 450 V rated substitute?

A: Higher voltage ratings provide increased design margin and improved reliability in applications subject to voltage transients or ripple current stress. 450 V rated parts additionally offer extended lifetime ratings (20000 Hrs @ 105°C versus 2000 Hrs @ 85°C), making them suitable for long-term reliability requirements.

Q: Are there mechanical differences between substitute parts?

A: All substitute parts maintain identical lead spacing (0.295" / 7.50mm) and case diameter (0.630" / 16.00mm). Height varies slightly: Nichicon and Rubycon parts measure 1.063" (27.00mm), while Chemi-Con parts measure 1.043" (26.50mm). Both heights are within standard PCB clearance tolerances and are mechanically interchangeable.

Q: Which substitute part should I select for new designs?

A: Select only from parts with Active product status: UAQ2G330MHD6, 400PX33MEFC16X25, EKMG351ELL330ML25S, EKMG401ELL330ML25S, EKMQ401ELL330ML25S, EKXF451ELL330ML25S, ESMG351ELL330ML25S, or ESMG401ELL330ML25S. The Nichicon UAQ2G330MHD6 (400 V, Active) is recommended for designs requiring Nichicon brand continuity.

Q: What is the difference between Chemi-Con KMG and SMG series?

A: Both series are 33 µF, ±20% tolerance, radial aluminum electrolytic capacitors with identical electrical and mechanical specifications. KMG series parts are rated for 2000 Hrs @ 105°C, while SMG series parts are rated for 2000 Hrs @ 85°C. Selection depends on application temperature requirements.

Q: Can I substitute a Rubycon or Chemi-Con part for the original Nichicon UVR2F330MHD?

A: Yes. All substitute parts meet the electrical and mechanical compatibility criteria. Rubycon 400PX33MEFC16X25 and Chemi-Con EKMG401ELL330ML25S or ESMG401ELL330ML25S are direct functional equivalents with Active product status and are suitable for production applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and suitable for regulated applications requiring environmental compliance certification.
