Key Parameters

Substitute Part Grouping Explanation

Substitution of the UES0J330MDM is determined by the following critical parameters:

Electrical Parameters:

• Capacitance value: 33 µF (fixed requirement)
• Tolerance: ±20% (fixed requirement)
• Voltage rating: Minimum 6.3 V (substitute parts may exceed this rating)
• Polarization: Bi-Polar (fixed requirement)

Mechanical Parameters:

• Lead spacing: 0.079" (2.00mm) (fixed requirement)
• Package type: Radial, Can (fixed requirement)
• Size / Dimension: 0.197" Dia (5.00mm) (fixed requirement)
• Mounting type: Through Hole (fixed requirement)

Environmental & Compliance Parameters:

• RoHS Status: ROHS3 Compliant (fixed requirement)
• Operating temperature range: Must support -40°C minimum and 85°C maximum

Substitute parts are grouped into two categories:

Upgrade Substitutes: Parts with identical capacitance, tolerance, lead spacing, package type, and mechanical dimensions, but with higher voltage ratings (16 V) and improved or equivalent lifetime ratings. These provide direct functional replacement with enhanced performance margins.

Similar Substitutes: Parts with identical capacitance, tolerance, lead spacing, package type, and mechanical dimensions, but with higher voltage ratings (25 V). These provide functional replacement with additional voltage margin.

Parameter Comparison

Engineering Selection Recommendations

UEP1C330MDD (Nichicon): Direct upgrade from the same manufacturer with identical mechanical dimensions and lead spacing. Provides higher voltage rating (16 V) and extended operating temperature range (-55°C ~ 105°C). Product status is obsolete; however, inventory availability is confirmed at 1181 pieces. Suitable for applications requiring enhanced voltage margin while maintaining the same form factor.

336BPS016M (Cornell Dubilier / Illinois Capacitor): Active product status ensures long-term availability and supply chain continuity. Provides 16 V voltage rating with doubled lifetime rating (2000 Hrs @ 85°C) compared to the original part. Height dimension is 0.512" (13.00mm), which is 0.020" taller than the original; verify PCB layout clearance before selection. Suitable for audio applications requiring extended operational life.

ECE-A1CN330U (Panasonic Electronic Components): Active product status with highest inventory availability (3193 pieces). Provides 16 V voltage rating and 2000 Hrs @ 85°C lifetime. Height dimension is 0.472" (12.00mm), which is 0.020" shorter than the original; this provides additional PCB clearance margin. Suitable for applications prioritizing supply chain stability and long-term availability.

25NXA33MEFC5X11 (Rubycon): Active product status with 25 V voltage rating, providing the highest voltage margin. Extended operating temperature range (-55°C ~ 105°C) and 1000 Hrs @ 105°C lifetime. Mechanical dimensions are identical to the original part. Suitable for applications requiring maximum voltage derating and wide temperature operation.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original UES0J330MDM?

A: Yes. All substitute parts listed have voltage ratings of 16 V or 25 V, which exceed the original 6.3 V rating. Higher voltage ratings provide additional safety margin and do not negatively impact circuit performance in applications designed for 6.3 V operation.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Mechanical compatibility depends on lead spacing, package type, and physical dimensions. All substitute parts maintain the same lead spacing (0.079" / 2.00mm) and package type (Radial, Can). Height variations exist: 336BPS016M is 0.020" taller (0.512" vs 0.492"), while ECE-A1CN330U is 0.020" shorter (0.472" vs 0.492"). Verify PCB layout clearance for height-sensitive applications.

Q: Which substitute part offers the best long-term supply availability?

A: ECE-A1CN330U (Panasonic) and 336BPS016M (Cornell Dubilier) both have active product status, ensuring ongoing manufacturing and supply chain support. ECE-A1CN330U has the highest current inventory (3193 pieces).

Q: What is the difference between "Upgrade" and "Similar" substitute classifications?

A: Upgrade substitutes (UEP1C330MDD, 336BPS016M, ECE-A1CN330U) provide 16 V ratings with equivalent or improved lifetime ratings. Similar substitutes (25NXA33MEFC5X11) provide 25 V ratings, offering maximum voltage derating but with the same 1000 Hrs @ 85°C lifetime as the original part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original UES0J330MDM.

Q: Can I substitute the UES0J330MDM in audio applications?

A: Yes. The original part is specified for audio applications. Substitute parts 336BPS016M and 25NXA33MEFC5X11 are also rated for audio applications. UEP1C330MDD and ECE-A1CN330U are rated for general purpose applications, which encompasses audio use cases.
