Parameter Comparison

Engineering Selection Recommendations

The 25TRV330M10X10.5 (Rubycon TRV series) is a direct substitute for the EMZE250ARA331MJA0G based on the following engineering criteria:

Electrical Equivalence: Both parts provide identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), and lifetime specification (8000 Hrs @ 105°C). High-frequency ripple current performance is identical at 850 mA @ 100 kHz.

Mechanical Compatibility: Both parts share identical diameter (10.00mm), surface mount land size (10.30mm x 10.30mm), and package configuration (Radial, Can - SMD). The height difference of 0.007" (0.20mm) between seated maximums is within typical PCB assembly tolerances for surface mount components.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage requirements.

Performance Enhancement: The substitute part exhibits lower impedance (120 mOhms versus 160 mOhms) and higher low-frequency ripple current capability (510 mA @ 120 Hz versus 425 mA), providing improved performance margins in general purpose applications.

Temperature Range: The substitute part extends the lower operating temperature limit to -40°C, providing broader environmental compatibility without compromising upper temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 25TRV330M10X10.5 be used as a direct replacement for the EMZE250ARA331MJA0G on existing PCBs?

A: Yes. Both parts share identical surface mount land size (10.30mm x 10.30mm), diameter (10.00mm), and package configuration (Radial, Can - SMD). The 0.007" height difference falls within standard PCB assembly tolerances and does not affect placement or soldering processes.

Q: Are there electrical performance differences between these parts?

A: Core electrical specifications are identical: 330 µF capacitance, 25 V rating, ±20% tolerance, and 8000 Hrs @ 105°C lifetime. The substitute part provides lower impedance (120 mOhms versus 160 mOhms) and higher low-frequency ripple current (510 mA @ 120 Hz versus 425 mA @ 120 Hz), representing performance improvements for general purpose applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EMZE250ARA331MJA0G and 25TRV330M10X10.5 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH unaffected and classified as EAR99 for export purposes.

Q: What is the operating temperature difference between these parts?

A: The original part operates from -25°C to 105°C. The substitute part extends the lower limit to -40°C while maintaining the same 105°C upper limit. This expanded range provides greater environmental flexibility without affecting performance in the original operating window.

Q: Are there any mechanical constraints when substituting these parts?

A: No mechanical constraints exist. Both parts are surface mount radial can capacitors with identical land sizes and mounting requirements. Standard SMD assembly equipment and processes apply to both parts without modification.

Q: Which part should be selected for new designs?

A: Selection between these parts depends on inventory availability and application-specific requirements. Both parts are Active status with equivalent electrical performance for general purpose applications. The substitute part's lower impedance and extended temperature range may provide advantages in demanding environments.
