Parameter Comparison

Engineering Selection Recommendations

All three capacitors listed—SM1V331MNN1012 (Chinsan), B41821A7337M000 (EPCOS - TDK), and ECA-1VM331 (Panasonic)—are Active products with ROHS3 compliance and meet the core electrical and mechanical specifications for direct substitution.

B41821A7337M000 (EPCOS - TDK Electronics) is a parametric equivalent with documented ESR of 700 mOhm @ 120 Hz and REACH Unaffected status. This part is suitable for applications where ESR specification is a design requirement.

ECA-1VM331 (Panasonic Electronic Components) is a parametric equivalent with REACH Unaffected status and Not Applicable MSL designation. This part is suitable for applications where moisture sensitivity is not a constraint.

Selection between these three parts is based on manufacturer preference, supply chain availability, and specific application requirements for ripple current handling or ESR performance.

Frequently Asked Questions (FAQ)

Q: Can B41821A7337M000 be used as a direct replacement for SM1V331MNN1012?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20%, 2000 Hrs @ 85°C) and mechanical dimensions (0.394" diameter, 0.531" height, 5.00mm lead spacing). Both are ROHS3 compliant and through-hole radial capacitors.

Q: Can ECA-1VM331 be used as a direct replacement for SM1V331MNN1012?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20%, 2000 Hrs @ 85°C) and mechanical dimensions (0.394" diameter, 0.531" height, 5.00mm lead spacing). Both are ROHS3 compliant and through-hole radial capacitors.

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

A: The SM1V331MNN1012 is rated for 550 mA @ 120 Hz and 825 mA @ 100 kHz. The B41821A7337M000 is rated for 490 mA @ 120 Hz. The ECA-1VM331 is rated for 440 mA @ 120 Hz and 748 mA @ 10 kHz. Applications requiring higher ripple current handling should reference the specific ripple current rating of the selected part.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts have identical lead spacing (5.00mm), diameter (10.00mm), and maximum seated height (13.50mm), making them mechanically interchangeable on through-hole PCB designs.

Q: What is the significance of ESR specification in B41821A7337M000?

A: ESR (Equivalent Series Resistance) of 700 mOhm @ 120 Hz is a documented electrical characteristic. Applications sensitive to ESR performance should use this specification for circuit analysis. The SM1V331MNN1012 and ECA-1VM331 do not have ESR values specified in their datasheets.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

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. The ECA-1VM331 has Not Applicable MSL, which is also acceptable for general applications.
