Substitute Part Grouping Explanation

Substitution for the LXZ6.3VB331M6X11LL is determined by strict equivalence across the following parameters:

Core Electrical Parameters:

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

Mechanical Parameters:

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

Performance Parameters:

• Ripple Current @ 120 Hz: 145 mA minimum
• Ripple Current @ 100 kHz: 290 mA minimum
• Impedance: 250 mOhms maximum

Substitute parts are classified into three categories: Direct Manufacturer (same manufacturer, same series), Similar Manufacturer (same manufacturer, same electrical specifications), and Parametric Equivalent (different manufacturer, matching electrical and mechanical specifications).

Engineering Selection Recommendations

ELXZ6R3ELL331MFB5D (Chemi-Con LXZ Series - Similar Manufacturer)

This part is the preferred substitute for the LXZ6.3VB331M6X11LL. It maintains identical electrical specifications, mechanical dimensions, and lead spacing. The ELXZ6R3ELL331MFB5D is currently in active production status and is ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. The primary design consideration is the increased seated height of 0.512" (13.00mm) compared to the original 0.453" (11.50mm), which requires verification of available PCB clearance in the target application.

UPW0J331MED (Nichicon UPW Series - Direct Manufacturer Equivalent)

This Nichicon component provides electrical equivalence with identical capacitance, voltage, tolerance, and lifetime specifications. The UPW0J331MED features a reduced seated height of 0.433" (11.00mm), which may provide advantages in space-constrained applications. However, this part is obsolete and ROHS3 compliant. The ripple current capability at 120 Hz is higher at 188.5 mA compared to the original 145 mA, indicating improved performance characteristics.

SEK331M6R3ST (Cornell Dubilier Electronics SEK Series - Parametric Equivalent)

This CDE component meets all core electrical and mechanical substitution criteria and is currently in active production with ROHS3 compliance. The seated height matches the original at 0.453" (11.50mm). The impedance specification differs at 1.05 Ohm @ 120 Hz, and the high-frequency ripple current is specified at 240 mA @ 10 kHz rather than 100 kHz. This part is suitable for applications where the impedance and ripple current characteristics are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can ELXZ6R3ELL331MFB5D be used as a direct replacement for LXZ6.3VB331M6X11LL?

A: ELXZ6R3ELL331MFB5D is electrically and mechanically equivalent with identical capacitance, voltage, tolerance, and lead spacing. The primary consideration is the increased seated height of 0.512" (13.00mm) versus 0.453" (11.50mm). PCB clearance must be verified before substitution.

Q: What is the difference between the three substitute parts?

A: ELXZ6R3ELL331MFB5D is from the same manufacturer (Chemi-Con) and series (LXZ) as the original part. UPW0J331MED is from Nichicon and offers a shorter profile. SEK331M6R3ST is from Cornell Dubilier Electronics and is currently in active production. All three meet the core electrical specifications of 330 µF, 6.3 V, ±20% tolerance, and 2000 Hrs @ 105°C lifetime.

Q: Are all substitute parts RoHS compliant?

A: ELXZ6R3ELL331MFB5D, UPW0J331MED, and SEK331M6R3ST are all ROHS3 compliant. The original LXZ6.3VB331M6X11LL is RoHS non-compliant.

Q: Does the increased height of ELXZ6R3ELL331MFB5D affect performance?

A: The increased seated height of 0.512" (13.00mm) does not affect electrical performance. It is a mechanical consideration that requires verification of available space on the PCB or within the enclosure.

Q: Can SEK331M6R3ST be used in all applications where LXZ6.3VB331M6X11LL was used?

A: SEK331M6R3ST meets all core electrical and mechanical specifications. The impedance specification of 1.05 Ohm @ 120 Hz and ripple current at 10 kHz should be evaluated against specific application requirements to ensure compatibility.

Q: Which substitute part has the best availability?

A: According to inventory data, UPW0J331MED has the highest stock level at 4863 pieces. ELXZ6R3ELL331MFB5D has 1010 pieces, and SEK331M6R3ST has 859 pieces in stock.

Q: Are there any certifications or ratings that differ between the parts?

A: ELXZ6R3ELL331MFB5D carries AEC-Q200 automotive qualification. The original LXZ6.3VB331M6X11LL and UPW0J331MED have no specific ratings listed. SEK331M6R3ST has no specific ratings listed. All parts are REACH unaffected and classified as EAR99 for export control purposes.
