Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1C153MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 15000 µF (exact match required)
• Rated voltage: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 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 type: Radial, Can - Snap-In (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

Two substitute parts meet these criteria: LLS1C153MELA (Nichicon) and SLPX153M016C3P3 (Cornell Dubilier Electronics). Both maintain identical electrical and mechanical specifications with the main part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LLS1C153MELZ, LLS1C153MELA, and SLPX153M016C3P3—are Active product status and ROHS3 Compliant, meeting current regulatory requirements. Selection between these parts should be based on:

1. Physical space constraints: The LLS1C153MELZ has a smaller diameter (22.00 mm) and greater height (37.00 mm) compared to the substitute parts, which have larger diameters (25.00 mm) but reduced heights (32.00 mm and 30.00 mm respectively). PCB layout compatibility must be verified.

2. Manufacturer preference: Both Nichicon variants (LLS1C153MELZ and LLS1C153MELA) are from the same manufacturer, while SLPX153M016C3P3 is from Cornell Dubilier Electronics.

3. Ripple current performance: All parts meet the specified ripple current requirements at 120 Hz. SLPX153M016C3P3 provides documented ESR specification (44 mOhm @ 120 Hz), which may be relevant for applications sensitive to impedance characteristics.

Frequently Asked Questions (FAQ)

Q: Can LLS1C153MELA be used as a direct replacement for LLS1C153MELZ?

A: Yes. Both parts are manufactured by Nichicon with identical electrical specifications (15000 µF, 16 V, ±20%, 3000 Hrs @ 85°C). Physical dimensions differ slightly; verify PCB layout compatibility before substitution.

Q: What are the physical differences between the main part and substitutes?

A: The LLS1C153MELZ has a 22.00 mm diameter and 37.00 mm height. Both substitute parts have 25.00 mm diameter but reduced heights: LLS1C153MELA at 32.00 mm and SLPX153M016C3P3 at 30.00 mm. Lead spacing remains constant at 10.00 mm across all three parts.

Q: Are all three parts ROHS3 compliant?

A: Yes. LLS1C153MELZ, LLS1C153MELA, and SLPX153M016C3P3 are all ROHS3 Compliant.

Q: What is the significance of ESR specification in SLPX153M016C3P3?

A: The SLPX153M016C3P3 provides documented ESR of 44 mOhm @ 120 Hz. ESR affects impedance characteristics in high-frequency applications. The main part and LLS1C153MELA do not specify ESR values.

Q: Can these parts be used interchangeably in all applications?

A: Electrical specifications are equivalent across all three parts. Physical dimensions must be verified against PCB layout requirements before substitution. Lead spacing is identical (10.00 mm), ensuring mechanical compatibility with standard through-hole footprints.

Q: What is the product status of these parts?

A: All three parts are classified as Active, indicating current availability and ongoing manufacturer support.
