EMLA250ARA331MHA0G Equivalent & Substitute Parts

Part Overview

The EMLA250ARA331MHA0G is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Chemi-Con in the Alchip™-MLA series. This surface mount radial can capacitor is designed for general purpose applications with a rated lifetime of 3000 hours at 105°C. The part is active and in production, with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained or enhanced, allowing direct replacement in circuit designs while meeting or exceeding original performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity is determined by the following criteria:

Primary Compatibility Requirements:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 25 V minimum (equal or higher acceptable)
• Package type: Radial, Can - SMD (exact match required)
• Case diameter: 0.315" (8.00mm) (exact match required)
• Surface mount land size: 0.327" L x 0.327" W (8.30mm x 8.30mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)

Secondary Enhancement Parameters:

• Lifetime @ 105°C: 3000 Hrs minimum (higher values acceptable)
• Operating temperature range: -40°C ~ 105°C minimum (wider ranges acceptable)
• Impedance: 160 mOhms reference (minor variations acceptable within electrical performance)
• RoHS compliance: ROHS3 (maintained across all substitutes)

All three substitute parts meet or exceed these criteria and are therefore valid direct replacements for the EMLA250ARA331MHA0G.

Parameter Comparison

Engineering Selection Recommendations

EMLA250ARA331MHA0G (Chemi-Con Alchip™-MLA Series)

Primary specification for general purpose applications. Baseline reference part with 3000-hour lifetime rating at 105°C. ROHS3 compliant. Suitable for non-automotive general purpose designs.

25TLV330M8X10.5 (Rubycon TLV Series)

Direct electrical equivalent with enhanced lifetime (5000 hours at 105°C). Extended operating temperature range (-55°C to 105°C). AEC-Q200 automotive qualification. Identical impedance (160 mOhms) and electrical performance. Height increase of 0.007" (0.20mm) is within typical PCB layout tolerances. Suitable for automotive and extended-life general purpose applications.

UUD1E331MNL1GS (Nichicon UUD Series)

Direct electrical equivalent with enhanced lifetime (5000 hours at 105°C). Extended operating temperature range (-55°C to 105°C). AEC-Q200 automotive qualification. Impedance 170 mOhms (10 mOhms higher than reference). Height increase of 0.007" (0.20mm) is within typical PCB layout tolerances. REACH Affected status. Suitable for automotive and extended-life general purpose applications.

EEE-FT1V331GP (Panasonic FT Series)

Voltage-upgraded equivalent (35 V rating vs. 25 V reference). Enhanced lifetime (5000 hours at 105°C). Extended operating temperature range (-55°C to 105°C). AEC-Q200 automotive qualification. Superior impedance performance (80 mOhms @ 100kHz). Height increase of 0.007" (0.20mm) is within typical PCB layout tolerances. Higher ripple current capability. Suitable for automotive applications and designs requiring voltage margin or higher ripple current handling.

Frequently Asked Questions (FAQ)

Q: Can the 25TLV330M8X10.5 replace the EMLA250ARA331MHA0G directly?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), case diameter (8.00mm), and land size (8.30mm x 8.30mm). The 25TLV330M8X10.5 offers enhanced lifetime (5000 vs. 3000 hours at 105°C) and extended temperature range (-55°C to 105°C). Height difference is 0.007" (0.20mm), which is within standard PCB layout tolerances.

Q: What is the difference between the UUD1E331MNL1GS and the reference part?

A: The UUD1E331MNL1GS maintains identical electrical specifications (330 µF, 25 V, ±20%) and package dimensions. It provides enhanced lifetime (5000 hours at 105°C) and extended operating temperature range (-55°C to 105°C). Impedance is 170 mOhms versus 160 mOhms in the reference part. REACH status differs (Affected vs. Unaffected).

Q: Why does the EEE-FT1V331GP have a 35 V rating instead of 25 V?

A: The EEE-FT1V331GP is a voltage-upgraded substitute. The higher voltage rating (35 V) provides additional design margin and is electrically compatible with 25 V circuit requirements. This part also delivers superior impedance performance (80 mOhms @ 100kHz) and higher ripple current capability (850 mA @ 100 kHz vs. 600 mA @ 100 kHz in the reference part).

Q: Are all substitute parts AEC-Q200 qualified?

A: The 25TLV330M8X10.5, UUD1E331MNL1GS, and EEE-FT1V331GP all carry AEC-Q200 automotive qualification. The reference part EMLA250ARA331MHA0G does not list AEC-Q200 qualification and is specified for general purpose applications.

Q: What is the height difference between the reference part and substitutes?

A: The EMLA250ARA331MHA0G has a maximum seated height of 0.406" (10.30mm). All three substitute parts have a maximum seated height of 0.413" (10.50mm), representing a 0.007" (0.20mm) increase. This difference is within standard PCB layout and component placement tolerances.

Q: Can I use the EEE-FT1V331GP in a 25 V circuit?

A: Yes. The EEE-FT1V331GP is rated for 35 V, which exceeds the 25 V circuit requirement. Higher voltage-rated capacitors are electrically compatible with lower voltage applications and provide additional safety margin.

Q: What is the ripple current difference between these parts?

A: At 100 kHz, the reference part handles 600 mA. The 25TLV330M8X10.5 and UUD1E331MNL1GS also handle 600 mA and 450 mA respectively. The EEE-FT1V331GP handles 850 mA at 100 kHz, providing 41.7% higher ripple current capacity.

Q: Are all parts ROHS3 compliant?

A: Yes. The EMLA250ARA331MHA0G, 25TLV330M8X10.5, UUD1E331MNL1GS, and EEE-FT1V331GP are all ROHS3 compliant.
