ELXZ6R3ELL331MFB5D Equivalent & Substitute Parts

Part Overview

The ELXZ6R3ELL331MFB5D is a 330 µF, 6.3 V aluminum electrolytic capacitor manufactured by Chemi-Con in the LXZ series. This radial, through-hole component is rated for 2000 hours at 105°C and is designed for automotive applications with AEC-Q200 compliance. The part is currently in active production status with 1010 units in stock.

Substitute parts are necessary when the primary component becomes unavailable, when design flexibility is required across manufacturing sources, or when inventory constraints necessitate alternative sourcing from qualified manufacturers. The substitute identified for this application maintains electrical and mechanical compatibility within the specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELXZ6R3ELL331MFB5D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Size / Dimension: 0.248" Dia (6.30mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The substitute part UPW0J331MED meets all critical electrical and mechanical parameters. Minor variations in height dimension and ripple current specifications do not affect functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Primary Component: ELXZ6R3ELL331MFB5D (Chemi-Con LXZ Series)

Selection of the primary component is appropriate for new designs and production applications. The part carries active product status, AEC-Q200 automotive qualification, and maintains full availability with 1010 units in current inventory. This component is suitable for automotive applications requiring certified reliability standards.

Substitute Component: UPW0J331MED (Nichicon UPW Series)

The UPW0J331MED is electrically and mechanically equivalent across all critical parameters. However, this component carries obsolete product status, indicating discontinued manufacturing. The substitute is suitable for legacy system maintenance, repair applications, or as a secondary sourcing option when primary component availability is constrained. The height dimension is 0.079" (2.00mm) shorter than the primary component; this variation must be evaluated against specific PCB layout constraints and mechanical clearance requirements in the target application.

Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can UPW0J331MED be used as a direct replacement for ELXZ6R3ELL331MFB5D in automotive applications?

A: The UPW0J331MED meets all critical electrical and mechanical parameters required for functional substitution. However, the primary component carries AEC-Q200 certification while the substitute does not list this rating. For automotive applications requiring AEC-Q200 compliance, the primary component ELXZ6R3ELL331MFB5D is the specified choice. The substitute is suitable for non-AEC-Q200 applications or legacy system repairs.

Q: What is the significance of the height dimension difference between these parts?

A: The ELXZ6R3ELL331MFB5D has a maximum seated height of 0.512" (13.00mm), while the UPW0J331MED measures 0.433" (11.00mm). This 0.079" (2.00mm) difference must be evaluated against PCB layout, component clearance, and mechanical assembly constraints. The shorter substitute may provide additional clearance in space-constrained designs but requires verification against specific board layout requirements.

Q: Why is the UPW0J331MED listed as obsolete?

A: Obsolete product status indicates that Nichicon has discontinued manufacturing of this component. While 4863 units remain in current inventory, future availability cannot be guaranteed. The primary component ELXZ6R3ELL331MFB5D is recommended for new designs to ensure long-term supply chain stability.

Q: Are the ripple current specifications identical between these parts?

A: Ripple current specifications differ at low frequency: the primary component is rated for 145 mA @ 120 Hz, while the substitute is rated for 188.5 mA @ 120 Hz. Both components are rated identically at high frequency (290 mA @ 100 kHz). The substitute's higher low-frequency ripple current rating indicates enhanced performance in this parameter and does not restrict substitution.

Q: Do both parts require the same PCB footprint?

A: Both components share identical lead spacing (0.098" / 2.50mm) and identical diameter (0.248" / 6.30mm), ensuring compatible PCB footprints. The height difference does not affect footprint compatibility but may affect vertical clearance in the assembly. PCB layout verification is required to confirm adequate clearance for the specific component selected.

Q: What compliance certifications apply to each component?

A: Both components are ROHS3 compliant and REACH unaffected. The primary component carries AEC-Q200 automotive qualification; the substitute does not list this certification. For applications requiring automotive-grade reliability standards, the primary component is the specified selection.
