Frequently Asked Questions (FAQ)

Q: Can APXA160ARA331MJC0G be used as a direct replacement for APXA160ARA331MJC0S?

A: Yes. APXA160ARA331MJC0G is a parametric equivalent with identical electrical specifications (330 µF, 16 V, 14 mOhm ESR, 15000 Hrs @ 105°C) and mechanical dimensions. The parts differ only in the final character of the part number suffix. Both are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between the Chemi-Con NPCAP™-PXA series parts and the Nichicon alternatives?

A: The Chemi-Con APXA160ARA331MJC0S and APXA160ARA331MJC0G parts offer 15000 Hrs @ 105°C lifetime rating with 14 mOhm ESR. Nichicon alternatives (PCJ1C331MCL1GS, PCV1C331MCL1GS, RPS1C331MCN1GS) provide 2000 to 3000 Hrs @ 105°C lifetime with ESR values ranging from 16 to 26 mOhm. Selection depends on application lifetime requirements and thermal stress conditions.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed parts maintain identical surface mount land size of 0.406" L x 0.406" W (10.30 mm x 10.30 mm) and identical diameter of 0.394" (10.00 mm). Height variations range from 0.394" to 0.500" (10.00 mm to 12.70 mm), which remain within standard radial can SMD package tolerances and do not affect PCB land pattern compatibility. Clearance verification is recommended for applications with height-constrained layouts.

Q: Which substitute part offers the best ripple current handling?

A: APXA160ARA331MJC0S and APXA160ARA331MJC0G both provide 5.05 A ripple current @ 100 kHz. Among alternatives, RPS1C331MCN1GS provides 4.8 A, 94SVP337X0016F12 provides 4.58 A, PCJ1C331MCL1GS provides 4.35 A, and PCV1C331MCL1GS provides 2.4 A. Selection should align with circuit ripple current requirements.

Q: What is the significance of REACH Affected status on certain substitute parts?

A: REACH Affected status indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Applications subject to REACH compliance requirements must use parts with REACH Unaffected status or conduct compliance assessment. APXA160ARA331MJC0S, APXA160ARA331MJC0G, 94SVP337X0016F12, and RPS1C331MCN1GS are REACH unaffected. PCJ1C331MCL1GS and PCV1C331MCL1GS are REACH affected.

Q: How does ESR variation affect circuit performance?

A: Equivalent Series Resistance (ESR) directly impacts voltage ripple, thermal dissipation, and transient response. Lower ESR values reduce voltage ripple and heat generation. The primary part and APXA160ARA331MJC0G both provide 14 mOhm ESR. Alternatives range from 16 to 26 mOhm. Applications with strict ripple voltage or thermal constraints should prioritize lower ESR values.

Q: What lifetime rating should be selected for long-term reliability applications?

A: The primary part APXA160ARA331MJC0S provides 15000 Hrs @ 105°C lifetime. For applications requiring extended operational life at elevated temperatures, this rating or the equivalent APXA160ARA331MJC0G is recommended. Alternatives provide 2000 to 3000 Hrs @ 105°C, suitable for applications with shorter operational life requirements or lower thermal stress conditions.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All listed parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
