Parameter Comparison

Engineering Selection Recommendations

Both the 397LBB200M2CC and 380LX391M200J012 are active production parts manufactured within the Cornell Dubilier family. Selection between these parts is based on availability and procurement requirements:

397LBB200M2CC (LBB Series): Primary selection when available. 668 units currently in stock. ESR of 425.09 mOhm @ 120Hz provides optimal performance for ripple current applications.

380LX391M200J012 (380LX Series): Direct substitute when primary part is unavailable. 782 units currently in stock. ESR of 470 mOhm @ 120Hz represents a 10.6% increase from the main part, remaining within acceptable operational parameters for general-purpose applications. Ripple current ratings at low frequency (1.7 A @ 120 Hz) and high frequency (2.4 A @ 20 kHz) are slightly lower than the main part but sufficient for equivalent circuit designs.

Both parts carry identical compliance certifications: ROHS3 Compliant, MSL 1 (Unlimited), and REACH Unaffected. Mechanical compatibility is guaranteed through identical lead spacing, diameter, height, and snap-in mounting configuration. Direct PCB footprint substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can 380LX391M200J012 be used as a direct replacement for 397LBB200M2CC on existing PCBs?

A: Yes. Both parts share identical mechanical specifications: 10.00 mm lead spacing, 25.00 mm diameter, 27.00 mm seated height, and radial snap-in mounting. PCB footprints are directly compatible without modification.

Q: What is the significance of the ESR difference between these parts?

A: The 397LBB200M2CC has an ESR of 425.09 mOhm @ 120Hz, while the 380LX391M200J012 has 470 mOhm @ 120Hz. This 10.6% difference falls within normal manufacturing tolerances for aluminum electrolytic capacitors and does not affect general-purpose applications. For ripple current-sensitive circuits, verify that the 380LX series ripple current ratings (1.7 A @ 120 Hz, 2.4 A @ 20 kHz) meet application requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both 397LBB200M2CC and 380LX391M200J012 are ROHS3 Compliant and REACH Unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operational temperature range for these capacitors?

A: Both parts operate across -40°C to 85°C. Rated lifetime is 3000 hours at 85°C for both parts.

Q: Can these capacitors be used interchangeably in high-ripple-current applications?

A: Ripple current ratings differ slightly. The 397LBB200M2CC supports 1.8 A @ 120 Hz and 2.646 A @ 10 kHz. The 380LX391M200J012 supports 1.7 A @ 120 Hz and 2.4 A @ 20 kHz. Verify application ripple current requirements against the selected part's specifications.

Q: What is the capacitance tolerance for both parts?

A: Both parts carry ±20% tolerance at 390 µF nominal capacitance, resulting in an acceptable range of 312 µF to 468 µF.

Q: Are these parts suitable for general-purpose applications?

A: Yes. Both parts are rated for general-purpose applications and carry active production status with substantial inventory availability.
