Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2A152MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1500 µF (exact match required)
• Rated voltage: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Lifetime rating: 3000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The LLS2A152MELA qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Variations in physical dimensions (diameter and height) and ripple current specifications remain within acceptable tolerances for general-purpose applications while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2A152MELZ and LLS2A152MELA maintain Active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these parts is based on physical space constraints and inventory availability. The LLS2A152MELZ features a smaller diameter (22.00mm) and greater height (37.00mm), while the LLS2A152MELA provides a larger diameter (25.00mm) with reduced height (32.00mm). PCB layout and enclosure dimensions determine which configuration is appropriate for a given application. Both parts deliver equivalent electrical performance across all specified parameters and are suitable for direct substitution in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can LLS2A152MELA replace LLS2A152MELZ in my circuit?

A: Yes. Both parts are electrically equivalent with identical capacitance (1500 µF), voltage rating (100 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), and operating temperature range (-40°C ~ 85°C). The primary difference is physical dimensions. Verify that your PCB layout and enclosure accommodate the LLS2A152MELA's larger diameter (25.00mm vs. 22.00mm) and shorter height (32.00mm vs. 37.00mm).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact matching of capacitance value, rated voltage, tolerance, polarization, package configuration (Radial, Can - Snap-In), mounting type (Through Hole), lead spacing (10.00mm), lifetime rating, operating temperature range, and compliance certifications. Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are there differences in ripple current handling between these parts?

A: Ripple current specifications differ slightly. The LLS2A152MELZ handles 2.45 A @ 120 Hz and 2.8175 A @ 50 kHz, while the LLS2A152MELA handles 2.47 A @ 120 Hz and 2.8405 A @ 50 kHz. These variations are minor and do not affect functional equivalence for general-purpose applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LLS2A152MELZ and LLS2A152MELA are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0040.

Q: What should I consider when selecting between these two parts?

A: Evaluate your available PCB space and enclosure dimensions. The LLS2A152MELZ is more compact in diameter but taller, while the LLS2A152MELA is wider but shorter. Both deliver identical electrical performance. Inventory availability may also influence selection, as the LLS2A152MELA currently has higher stock levels (1255 Pcs vs. 727 Pcs).
