Parameter Comparison

Engineering Selection Recommendations

The LLS1K103MELC from Nichicon is a qualified substitute for the LP103M080H9P3. Both parts are Active in product status and maintain ROHS3 compliance and REACH unaffected classification. The substitute part meets all critical electrical and mechanical specifications for direct board-level replacement.

The operating temperature range of the substitute part extends to 85°C maximum, compared to 105°C for the primary part. Applications operating continuously at temperatures above 85°C require verification against the specific thermal environment. The substitute part provides extended lifetime rating at 85°C (3000 Hrs) compared to the primary part at 105°C (1000 Hrs), indicating superior performance stability in the lower temperature operating window.

Both parts are suitable for general-purpose applications and maintain identical footprint and lead spacing characteristics for through-hole mounting on standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can LLS1K103MELC replace LP103M080H9P3 in all applications?

A: LLS1K103MELC meets all critical electrical and mechanical specifications for direct substitution. Applications operating continuously above 85°C should evaluate thermal performance against specific design requirements, as the substitute part is rated to 85°C maximum operating temperature compared to 105°C for the primary part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (0.394" / 10.00mm), diameter (1.378" / 35.00mm), and mounting type (Through Hole, Radial Can - Snap-In). The substitute part height is 2.047" (52.00mm) compared to 1.969" (50.00mm) for the primary part. This 2mm difference must be verified against PCB clearance constraints in the specific application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both LP103M080H9P3 and LLS1K103MELC are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the difference in capacitance tolerance between these parts?

A: Both parts share identical ±20% tolerance specification. Capacitance value is 10000 µF for both parts.

Q: Are ripple current ratings provided for the primary part?

A: Ripple current specifications are not provided for the LP103M080H9P3. The substitute part LLS1K103MELC specifies 6.63 A @ 120 Hz and 7.6245 A @ 50 kHz. Applications with specific ripple current requirements should reference the primary manufacturer's detailed datasheet.
