EMVA160ARA331MHA0G Equivalent & Substitute Parts

Part Overview

The EMVA160ARA331MHA0G is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Chemi-Con in the Alchip™ MVA series. This surface mount radial can capacitor is rated for 2000 hours at 85°C and operates across a temperature range of -40°C to 85°C. The component is designed for general purpose applications and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand enhanced thermal performance, when higher voltage ratings are required for circuit margin, or when automotive-grade certifications are mandated by application specifications.

Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Package type: Radial, Can - SMD (physical and electrical compatibility)
Mounting type: Surface Mount (PCB assembly compatibility)
Physical dimensions: 0.315" diameter, compatible height range (10.00mm to 10.50mm acceptable)
Polarization: Polar (required for electrolytic capacitor function)

Secondary Substitution Criteria:

Lifetime rating: 2000 hours minimum at rated temperature
Operating temperature range: Must encompass -40°C to 85°C minimum
Ripple current capability: Must meet or exceed application requirements

Engineering Selection Recommendations

For Direct Replacement (Same Thermal and Voltage Specifications):

The EMVY160ARA331MHA0G from Chemi-Con provides a direct functional equivalent with enhanced thermal performance. Both parts maintain 330 µF capacitance and 16 V rating with identical physical dimensions. The EMVY series extends the operating temperature range to -55°C and improves ripple current handling to 450 mA at 100 kHz compared to 291.6 mA in the original EMVA series. Both are ROHS3 compliant and carry unlimited MSL rating.

For Extended Thermal Performance (16 V Rating with Enhanced Temperature Range):

The EMVE160ARA331MHA0G, 16TRV330M8X10.5, AFK337M16F24T-F, EEE-FK1C331P, and EEV337M016A9MAA all provide extended operating temperature ranges to -55°C or -40°C upper limit of 105°C. The 16TRV330M8X10.5 offers the longest lifetime rating at 8000 hours at 105°C. The AFK337M16F24T-F, EEE-FK1C331P, and EEV337M016A9MAA are AEC-Q200 rated automotive-grade components with 160 mOhm impedance at 100 kHz and 600 mA ripple current capability.

Frequently Asked Questions (FAQ)

Q: Can EMVY160ARA331MHA0G replace EMVA160ARA331MHA0G in all applications?

A: Yes, for applications operating within -40°C to 85°C. The EMVY series provides identical capacitance, voltage rating, and physical dimensions with enhanced ripple current capability (450 mA vs. 291.6 mA at 100 kHz). If the application requires operation below -40°C, the EMVY series extends to -55°C, providing additional margin.

Q: What is the difference between 16 V and 25 V rated parts?

A: The 25 V rated parts (EMZA250ARA331MHA0G, EMZJ250ARA331MHA0G, EMVA250ARA331MHA0G) provide higher voltage margin for the same 330 µF capacitance. These are used when circuit design requires additional safety margin or when the capacitor may experience voltage transients. Physical dimensions remain compatible with the original 16 V design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the EMVA160ARA331MHA0G.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. Parts carrying this rating (16SEV330M8X10.5, AFK337M16F24T-F, EEE-FK1C331P, EMZA250ARA331MHA0G, EMZJ250ARA331MHA0G) meet automotive reliability, temperature cycling, and performance requirements and are suitable for automotive applications.

Q: Can I use a part with higher ripple current rating than required?

A: Yes. Higher ripple current capability indicates the capacitor can handle greater AC current stress. Using a part with higher ripple current rating than required does not degrade performance and provides additional design margin.

Q: What is the significance of lifetime rating differences?

A: Lifetime rating indicates the number of hours a capacitor maintains specified performance at a given temperature. The 16TRV330M8X10.5 offers 8000 hours at 105°C compared to 2000 hours for most other parts. Extended lifetime ratings provide longer component life in high-temperature applications.

Q: Are there physical dimension differences between substitute parts?

A: Yes. Most substitute parts have a maximum height of 0.413" (10.50mm) compared to 0.394" (10.00mm) for the original EMVA160ARA331MHA0G. The EMZJ250ARA331MHA0G is 0.406" (10.30mm). All maintain the same 0.315" diameter and compatible land size patterns. Verify PCB clearance before substitution.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed substitute parts carry MSL 1 rating.

Q: Can I substitute a part with different packaging (Cut Tape vs. Tape & Reel)?

A: Packaging affects supply chain and assembly processes but not electrical performance. The EMVA250ARA331MHA0G uses Cut Tape packaging while most others use Tape & Reel. Verify your assembly equipment compatibility before selecting based on packaging type.
