Equivalent & Substitute Parts for LLS1C223MELZ

Part Overview

The LLS1C223MELZ is a 22000 µF, 16 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in capacitor is rated for 3000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part is Active in product status and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, and lifetime rating) and compatible mechanical form factors (through-hole radial mounting, snap-in package style, and lead spacing).

Substitute Part Grouping Explanation

Substitution for the LLS1C223MELZ is determined by strict equivalence in the following electrical and mechanical parameters:

Capacitance value: 22000 µF (exact match required)
Voltage rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime rating: 3000 Hrs @ 85°C (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package style: Radial, Can - Snap-In (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (diameter and height) are permissible within the snap-in radial form factor, provided the lead spacing and mounting footprint remain compatible with the original design.

Engineering Selection Recommendations

All substitute parts listed—LLS1C223MELA, LLS1C223MELB, and SLPX223M016E3P3—are Active in product status and ROHS3 compliant, meeting the same regulatory and compliance requirements as the primary part LLS1C223MELZ. Selection among these equivalents should be based on physical space constraints within the application, as the primary difference between parts is the can diameter and height. The Nichicon LLS series parts (LLS1C223MELA and LLS1C223MELB) maintain manufacturer consistency, while the Cornell Dubilier SLPX223M016E3P3 provides an alternative from a different manufacturer with identical electrical specifications and compliance status.

Frequently Asked Questions (FAQ)

Q: Can LLS1C223MELA be used as a direct replacement for LLS1C223MELZ?

A: Yes. Both parts share identical electrical specifications: 22000 µF capacitance, 16 V voltage rating, ±20% tolerance, and 3000 Hrs @ 85°C lifetime. Both use the same 0.394" (10.00 mm) lead spacing and through-hole snap-in mounting. The difference is physical size: LLS1C223MELA has a 0.984" (25.00 mm) diameter and 1.654" (42.00 mm) height, compared to LLS1C223MELZ at 0.866" (22.00 mm) diameter and 2.047" (52.00 mm) height. Verify available board space before substitution.

Q: What is the difference between the Nichicon LLS parts and the Cornell Dubilier SLPX223M016E3P3?

A: All four parts are electrically equivalent with matching capacitance, voltage, tolerance, and lifetime ratings. The primary differences are manufacturer and physical dimensions. SLPX223M016E3P3 is manufactured by Cornell Dubilier Electronics and has a 1.181" (30.00 mm) diameter and 1.181" (30.00 mm) height. All parts are ROHS3 compliant and suitable for general-purpose applications.

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

A: All parts share the same 0.394" (10.00 mm) lead spacing, which determines PCB hole placement. However, physical can dimensions vary. Verify that the available board space accommodates the specific diameter and height of the substitute part selected. The snap-in mounting style is consistent across all parts.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed parts—LLS1C223MELZ, LLS1C223MELA, LLS1C223MELB, and SLPX223M016E3P3—are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.
