Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical compatibility:

Direct Equivalents (Same Voltage Rating - 16V):

• 16TRV330M8X10.5 (Rubycon TRV series)
• UUD1C331MNL1GS (Nichicon UUD series)

These parts maintain the 16 V voltage rating and 330 µF capacitance. Substitution is valid when the physical dimensions, mounting type, and surface mount land size are identical. The key differentiators are lifetime rating, ripple current capability, impedance, and operating temperature range.

Upgraded Voltage Ratings (Higher Voltage - 25V or 35V):

• 25TLV330M8X10.5 (Rubycon TLV series, 25V)
• UUD1E331MNL1GS (Nichicon UUD series, 25V)
• EEE-FT1V331GP (Panasonic FT series, 35V)

These parts provide higher voltage ratings while maintaining 330 µF capacitance and identical physical footprint. Upgraded voltage ratings are substitutable when circuit design permits operation at higher voltage margins. All substitute parts share the same 0.315" diameter, 8.30mm x 8.30mm surface mount land size, and radial can SMD package configuration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same 16V Rating):

The 16TRV330M8X10.5 (Rubycon TRV series) is the preferred direct equivalent. It maintains identical electrical specifications (330 µF, 16 V, ±20% tolerance) and physical dimensions. The TRV series offers extended lifetime of 8000 hours at 105°C compared to the EMLA160ARA331MHA0G's 3000 hours, with equivalent ripple current handling (600 mA @ 100 kHz) and lower impedance (150 mOhms vs. 160 mOhms). Both parts are RoHS3 compliant and MSL 1 rated.

The UUD1C331MNL1GS (Nichicon UUD series) is an alternative direct equivalent at 16 V. This part is AEC-Q200 rated and automotive qualified, with extended operating temperature range (-55°C to 105°C). However, it exhibits lower ripple current capability (450 mA @ 100 kHz) and higher impedance (170 mOhms). Packaging differs as Cut Tape with Digi-Reel® option. Selection of UUD1C331MNL1GS is appropriate when automotive qualification and extended temperature range are circuit requirements.

For Upgraded Voltage Ratings:

The 25TLV330M8X10.5 (Rubycon TLV series) and UUD1E331MNL1GS (Nichicon UUD series) both provide 25 V rating with 330 µF capacitance. Both are AEC-Q200 rated and automotive qualified. The TLV series offers 5000-hour lifetime at 105°C with 600 mA ripple current capability. The UUD1E series provides 5000-hour lifetime with 450 mA ripple current. Selection between these depends on ripple current requirements and preferred manufacturer qualification status.

The EEE-FT1V331GP (Panasonic FT series) provides the highest voltage rating at 35 V with 330 µF capacitance. This part features the lowest impedance (80 mOhms @ 100 kHz) and highest ripple current capability (850 mA @ 100 kHz). It is AEC-Q200 rated and automotive qualified. The EEE-FT1V331GP is selected when maximum voltage margin and superior high-frequency ripple current performance are required.

All substitute parts maintain identical physical footprint (0.315" diameter, 8.30mm x 8.30mm land size) and surface mount compatibility. Height variation (0.406" to 0.413") is within typical PCB assembly tolerances for radial can capacitors.

Frequently Asked Questions (FAQ)

Q: Can the 16TRV330M8X10.5 directly replace the EMLA160ARA331MHA0G?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.315" diameter, 8.30mm x 8.30mm land size), and surface mount configuration. The TRV series provides superior lifetime (8000 hours vs. 3000 hours at 105°C) and lower impedance (150 mOhms vs. 160 mOhms). No circuit redesign is required.

Q: What is the difference between direct equivalents and upgraded voltage ratings?

A: Direct equivalents maintain the same 16 V voltage rating as the EMLA160ARA331MHA0G. Upgraded voltage ratings (25 V or 35 V) provide higher voltage margins for the same 330 µF capacitance. Upgraded parts are substitutable only when circuit design permits operation at higher voltage ratings. Physical footprint remains identical across all substitute options.

Q: Why do some substitute parts have lower ripple current ratings?

A: Ripple current capability depends on internal construction and thermal design of each manufacturer's series. The UUD1C331MNL1GS and UUD1E331MNL1GS (Nichicon) are rated at 450 mA @ 100 kHz, lower than the EMLA160ARA331MHA0G's 600 mA. Selection should verify that circuit ripple current requirements do not exceed the substitute part's rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and MSL 1 rated (Unlimited moisture sensitivity level). REACH status varies: the EMLA160ARA331MHA0G and Rubycon parts are REACH Unaffected; Nichicon parts are REACH Affected.

Q: What is the significance of AEC-Q200 rating?

A: AEC-Q200 is an automotive qualification standard. The 25TLV330M8X10.5, EEE-FT1V331GP, UUD1C331MNL1GS, and UUD1E331MNL1GS are AEC-Q200 rated. The EMLA160ARA331MHA0G and 16TRV330M8X10.5 are not AEC-Q200 rated. Selection of AEC-Q200 parts is required for automotive applications.

Q: Can the height difference (0.406" vs. 0.413") affect PCB assembly?

A: The 0.007" (0.18mm) height difference is within standard PCB assembly tolerances for radial can capacitors. Both heights are compatible with standard surface mount pick-and-place equipment and reflow processes. No design modification is required.

Q: Which substitute part offers the best impedance performance?

A: The EEE-FT1V331GP (Panasonic FT series) provides the lowest impedance at 80 mOhms @ 100 kHz, compared to 160 mOhms for the EMLA160ARA331MHA0G. Lower impedance reduces voltage ripple and improves high-frequency filtering performance. The 16TRV330M8X10.5 offers 150 mOhms, a modest improvement over the main part.

Q: What packaging options are available?

A: Most substitute parts are supplied in Tape & Reel (TR) packaging. The UUD1C331MNL1GS is available in Cut Tape (CT) with Digi-Reel® option. Packaging selection depends on production volume and assembly line requirements.
