Engineering Selection Recommendations

The EKXG401ELL151MM40S is the direct equivalent substitute for the obsolete KXG400VB151M18X40LL. Selection of this substitute is based on the following engineering factors:

Product Status: The KXG400VB151M18X40LL is obsolete. The EKXG401ELL151MM40S maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance Certifications: The substitute part is ROHS3 compliant, whereas the original part is RoHS non-compliant. This upgrade aligns with current regulatory requirements for electronic components in regulated markets.

Electrical and Mechanical Equivalence: All critical parameters—capacitance, voltage rating, tolerance, temperature range, ripple current specifications, and physical dimensions—are identical between the two parts. This ensures direct pin-to-pin and form-factor compatibility on existing circuit boards.

Packaging: The substitute is supplied in bulk packaging, which may differ from the original part's packaging format but does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can EKXG401ELL151MM40S be used as a direct replacement for KXG400VB151M18X40LL on existing circuit boards?

A: Yes. The substitute part is electrically and mechanically identical. All capacitance, voltage, tolerance, temperature, ripple current, and physical dimension specifications match exactly. Through-hole mounting and radial can package configuration are identical, enabling direct board-level substitution without design modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance certification. The KXG400VB151M18X40LL is obsolete and RoHS non-compliant. The EKXG401ELL151MM40S is an active product that is ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any temperature or ripple current limitations when using the substitute?

A: No. The operating temperature range (-40°C ~ 105°C) and ripple current ratings (985 mA @ 120 Hz and 2.21625 A @ 100 kHz) are identical. The substitute part maintains the same 10000-hour lifetime at 105°C.

Q: Does the packaging format affect compatibility?

A: No. The substitute is supplied in bulk packaging rather than the original packaging format, but this affects only procurement and handling. The component itself—its electrical characteristics, physical dimensions, and mounting interface—remains unchanged.

Q: What certifications does the substitute part hold?

A: The EKXG401ELL151MM40S is ROHS3 compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Is the lead spacing identical between the two parts?

A: Yes. Both parts have 0.295" (7.50 mm) lead spacing, 0.709" (18.00 mm) diameter, and 1.575" (40.00 mm) maximum seated height. PCB footprints are identical.
