Equivalent & Substitute Parts for LLS1V392MELZ

Part Overview

The LLS1V392MELZ is a 3900 µF, 35 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified to provide alternative sourcing options when the primary manufacturer part is unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1V392MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 3900 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V (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)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Diameter: 0.866" (22.00mm) (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part SLPX392M035A1P3 manufactured by Cornell Dubilier Electronics (CDE) meets all critical electrical and mechanical parameters. Minor variations in height dimension and ripple current specifications at different frequencies do not affect functional substitutability in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS1V392MELZ and SLPX392M035A1P3 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability: The SLPX392M035A1P3 currently has higher inventory (2873 pcs) compared to LLS1V392MELZ (903 pcs).
• Physical Fit: The SLPX392M035A1P3 has a reduced seated height of 0.984" (25.00mm) versus 1.063" (27.00mm) for the LLS1V392MELZ. This 2 mm difference may be advantageous in space-constrained PCB layouts.
• Electrical Performance: Both parts deliver identical capacitance, voltage rating, tolerance, and ripple current at 120 Hz. The CDE part provides specified ESR data (136 mOhm @ 120 Hz), which may be beneficial for detailed circuit analysis.
• Regulatory Compliance: Both parts meet identical compliance requirements and are suitable for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can SLPX392M035A1P3 be used as a direct replacement for LLS1V392MELZ?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 3900 µF capacitance, ±20% tolerance, 35 V rating, 3000 Hrs @ 85°C lifetime, identical operating temperature range, and snap-in radial package with 10 mm lead spacing and 22 mm diameter. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference in physical dimensions?

A: The seated height differs by 2 mm. The LLS1V392MELZ has a maximum seated height of 1.063" (27.00mm), while the SLPX392M035A1P3 measures 0.984" (25.00mm). The diameter remains identical at 0.866" (22.00mm) for both parts. Verify PCB clearance requirements before substitution.

Q: Are the electrical specifications identical?

A: Both parts meet the same capacitance (3900 µF), tolerance (±20%), voltage (35 V), and ripple current at 120 Hz (2.22 A). The CDE part provides specified ESR of 136 mOhm @ 120 Hz, while the Nichicon part does not specify ESR. Ripple current at high frequency differs slightly (2.553 A @ 50 kHz for Nichicon versus 2.78 A @ 20 kHz for CDE), but both support general-purpose applications.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both LLS1V392MELZ and SLPX392M035A1P3 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0040.

Q: Which part should I select for new designs?

A: Selection depends on availability, inventory levels, and physical space constraints. Both parts are active production components suitable for equivalent applications. The CDE part offers a compact height advantage and specified ESR data. Verify lead times and cost with your component supplier.
