Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of the 6.3 V SXR102M6R3ST?

A: Yes. A 16 V rated capacitor is electrically compatible in a circuit designed for 6.3 V operation. The higher voltage rating provides additional safety margin and does not affect circuit function. The capacitance value (1000 µF) and tolerance (±20%) remain identical, ensuring equivalent electrical behavior. Physical dimensions must be verified to confirm PCB fit.

Q: What is the difference between EEU-FM0J102 and EEU-FM0J102B?

A: Both parts are electrically identical: 1000 µF, 6.3 V, ±20% tolerance, manufactured by Panasonic in the FM-A series. The difference is packaging: EEU-FM0J102 is supplied in Bulk packaging, while EEU-FM0J102B is supplied in Cut Tape (CT) packaging. Cut Tape packaging is suitable for automated pick-and-place assembly; Bulk packaging is suitable for manual assembly or reel-fed systems. Select based on assembly process requirements.

Q: Why is the height of substitute parts different from the original SXR102M6R3ST?

A: Direct equivalent parts (EEU-FM0J102, EKZE6R3ELL102MJC5S) have reduced height (14.00 mm vs. 20.00 mm original) due to different internal construction and case design by different manufacturers. Upgrade parts (16 V rated) have increased height (21.50–22.00 mm) due to larger internal capacitor elements required for higher voltage rating. Height differences must be verified against PCB layout constraints, including component clearance and solder joint accessibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—EEU-FM0J102, EEU-FM0J102B, EKZE6R3ELL102MJC5S, EEU-EB1C102, EKZE160ELL102MJ20S, UHE1C102MPD, UPW1C102MPD, and EEU-FR1V102B—are ROHS3 compliant. This ensures compatibility with modern manufacturing standards and regulatory requirements.

Q: What does "Not For New Designs" status mean?

A: "Not For New Designs" indicates that the manufacturer (Nichicon, in the case of UHE1C102MPD and UPW1C102MPD) has discontinued active development and marketing of the part. These parts remain available for replacement in existing equipment but should not be selected for new product designs. New designs should use parts with Active status to ensure long-term availability and manufacturer support.

Q: Can I substitute the SXR102M6R3ST with a 35 V rated capacitor (EEU-FR1V102B)?

A: Yes, electrically. EEU-FR1V102B is compatible in circuits designed for 6.3 V operation due to its higher 35 V rating. However, this part has a larger diameter (12.50 mm vs. 10.00 mm), which may not fit existing PCB layouts designed for the original 10.00 mm diameter. Verify PCB clearance and component spacing before selection.

Q: What is the significance of ripple current ratings?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current capability (measured at 120 Hz and 100 kHz) indicates better performance in high-frequency switching applications. Direct equivalents and upgrade parts from Panasonic and Chemi-Con generally offer equal or superior ripple current handling compared to the original SXR102M6R3ST, improving circuit reliability.

Q: Which substitute part offers the longest lifetime at 105°C?

A: EEU-EB1C102 and EEU-FR1V102B both offer 10000 hours lifetime at 105°C, compared to the original 4000 hours. These parts provide 2.5× longer operational life, enhancing system reliability in high-temperature environments. UHE1C102MPD offers 7000 hours, and UPW1C102MPD offers 5000 hours.
