Engineering Selection Recommendations

The EKXG451ELL820MMP1S is a direct parametric equivalent to the KXG450VB82RM18X35LL across all electrical and mechanical specifications. Selection of the substitute part is supported by the following factors:

Product Status: The original KXG450VB82RM18X35LL is obsolete, while the EKXG451ELL820MMP1S maintains active product status with confirmed inventory availability (16,262 units in stock). This ensures long-term supply continuity for repair and replacement operations.

Regulatory Compliance: The substitute part achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This upgrade in compliance status aligns with current environmental and regulatory requirements without altering electrical or mechanical performance.

Electrical Equivalence: All critical electrical parameters—capacitance, voltage rating, tolerance, ripple current specifications, and thermal lifetime—are identical between the original and substitute parts. No circuit redesign or performance adjustment is required.

Mechanical Compatibility: Lead spacing, package dimensions, and mounting configuration are identical, ensuring direct board-level compatibility without layout modifications.

The EKXG451ELL820MMP1S is suitable for direct substitution in all applications where the KXG450VB82RM18X35LL was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the EKXG451ELL820MMP1S be used as a direct replacement for the KXG450VB82RM18X35LL?

A: Yes. The EKXG451ELL820MMP1S is a parametric equivalent with identical electrical and mechanical specifications. All key parameters—capacitance (82 µF), voltage rating (450 V), tolerance (±20%), ripple current ratings, thermal lifetime, lead spacing, and package dimensions—match exactly. No circuit modifications or board layout changes are required.

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

A: The primary differences are product status and regulatory compliance. The KXG450VB82RM18X35LL is obsolete and RoHS non-compliant, while the EKXG451ELL820MMP1S is an active product with ROHS3 compliance. Electrical and mechanical performance are identical.

Q: Are there any packaging differences between these parts?

A: The original part (KXG450VB82RM18X35LL) is supplied in standard packaging, while the substitute (EKXG451ELL820MMP1S) is supplied in bulk packaging. Both use identical radial, can package formats with through-hole mounting. Packaging format does not affect component performance or board compatibility.

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 0.295 inches (7.50 mm), ensuring compatibility with standard through-hole PCB layouts designed for the original component.

Q: Are the ripple current ratings the same?

A: Yes. Both parts are rated for 715 mA ripple current at 120 Hz and 1.7875 A ripple current at 100 kHz. Thermal and electrical performance under ripple current conditions is identical.

Q: What is the thermal lifetime specification?

A: Both parts are rated for 10,000 hours of operation at 105°C, providing equivalent reliability and service life in high-temperature applications.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. ROHS3 compliance is an environmental and regulatory attribute that does not alter electrical performance, mechanical fit, or functional compatibility. The upgrade in compliance status is beneficial for systems subject to environmental regulations.
