EMZE160ARA331MHA0G Equivalent & Substitute Parts

Part Overview

The EMZE160ARA331MHA0G is a 330 µF, 16 V aluminum electrolytic capacitor manufactured by Chemi-Con in the Alchip™ MZE series. This surface mount radial can capacitor is designed for general purpose applications requiring stable capacitance and extended operational life. The component is rated for 8000 hours at 105°C and operates across a temperature range of -25°C to 105°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, substitute parts may be required due to inventory availability, lead time constraints, or specific application performance requirements while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 16TRV330M8X10.5 from Rubycon is a direct equivalent substitute for the EMZE160ARA331MHA0G from Chemi-Con. Both components are active products with ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compliance across applications.

Electrical Equivalence: Both parts maintain identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), and high-frequency ripple current rating (600 mA @ 100 kHz). The Rubycon substitute provides superior low-frequency ripple current performance (360 mA vs. 300 mA @ 120 Hz) and lower impedance (150 mOhms vs. 220 mOhms), resulting in reduced heat generation and improved transient response characteristics.

Mechanical Compatibility: The substitute part shares identical diameter (0.315" / 8.00mm) and surface mount land size (0.327" L x 0.327" W / 8.30mm x 8.30mm). The height difference of 0.007" (0.20mm) between the two components is negligible for PCB assembly and does not affect board-level clearance or thermal management.

Temperature Performance: The Rubycon part extends the lower operating temperature limit to -40°C compared to -25°C for the Chemi-Con original, providing enhanced performance in cold environment applications while maintaining identical upper temperature rating and lifetime specification.

Frequently Asked Questions (FAQ)

Q: Can the 16TRV330M8X10.5 be used as a direct replacement for the EMZE160ARA331MHA0G?

A: Yes. Both components share identical electrical specifications (330 µF, 16 V, ±20% tolerance, 8000 Hrs @ 105°C), identical mechanical dimensions (0.315" diameter, 8.30mm x 8.30mm land size), and identical compliance certifications (ROHS3, MSL 1). The components are pin-compatible and footprint-compatible for surface mount assembly.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Chemi-Con vs. Rubycon), series designation (Alchip™ MZE vs. TRV), and performance enhancements in the substitute. The Rubycon part offers lower impedance (150 mOhms vs. 220 mOhms), higher low-frequency ripple current rating (360 mA vs. 300 mA @ 120 Hz), extended lower temperature operation (-40°C vs. -25°C), and slightly greater height (0.413" vs. 0.406").

Q: Are there any PCB layout considerations when substituting these parts?

A: No significant layout changes are required. The surface mount land size is identical (0.327" L x 0.327" W / 8.30mm x 8.30mm). The height difference of 0.007" (0.20mm) is negligible and does not affect component clearance, solder reflow profiles, or thermal management design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EMZE160ARA331MHA0G and 16TRV330M8X10.5 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both are active products with no known obsolescence or supply restrictions.

Q: Which part should be selected for new designs?

A: Selection depends on availability and supply chain requirements. Both parts are functionally equivalent. The Rubycon 16TRV330M8X10.5 offers performance advantages (lower impedance, higher ripple current, extended temperature range) and higher current inventory availability (2400 pcs vs. 768 pcs).

Q: Is the impedance difference significant for circuit performance?

A: The impedance difference (150 mOhms vs. 220 mOhms) represents a 32% reduction in the substitute part. This results in lower ESR heating and improved transient voltage response, which is beneficial for power supply filtering and decoupling applications. The difference is not detrimental to circuit function but may improve overall system performance.
