Substitute Part Grouping Explanation

Substitution of the LXZ63VB331M12X20LL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 7000 Hrs @ 105°C (exact match required)
Operating Temperature: -55°C ~ 105°C (exact match required)
Ripple Current capability at both 120 Hz and 100 kHz (must meet or exceed specified values)
Impedance: 85 mOhms (exact match required)

Mechanical Equivalence Criteria:

Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Two substitute parts meet these criteria:

ELXZ630ELL331MK20S (Chemi-Con LXZ series) – Same manufacturer, active product status, automotive-grade with AEC-Q200 certification, RoHS3 compliant. Height differs by 0.059" (1.50 mm).
UPW1J331MHD (Nichicon UPW series) – Different manufacturer, not for new designs status, general-purpose application, RoHS3 compliant. Identical height and form factor.

Engineering Selection Recommendations

For Active Production and New Designs: ELXZ630ELL331MK20S is the primary substitute. This Chemi-Con component maintains the same manufacturer lineage as the original part, carries active product status, and holds AEC-Q200 automotive qualification. RoHS3 compliance aligns with current regulatory requirements. The 0.059" (1.50 mm) height increase must be verified against PCB layout constraints and enclosure clearances. This part is suitable for both legacy system support and new product development.

For Legacy System Maintenance: UPW1J331MHD provides an alternative from Nichicon with identical form factor and height to the original LXZ63VB331M12X20LL. RoHS3 compliance is achieved. The "Not For New Designs" status indicates this part is available for existing system repairs but should not be selected for new development. The higher ripple current capability at 120 Hz (838.5 mA versus 645 mA) provides additional thermal margin in low-frequency applications.

Compliance Considerations: Both substitute parts achieve RoHS3 compliance, addressing environmental and regulatory requirements that the obsolete original part does not meet. Selection between ELXZ630ELL331MK20S and UPW1J331MHD depends on design phase (new versus legacy), application requirements (automotive versus general-purpose), and PCB layout constraints related to component height.

Frequently Asked Questions (FAQ)

Q: Can ELXZ630ELL331MK20S be used as a direct replacement for LXZ63VB331M12X20LL?

A: ELXZ630ELL331MK20S meets all electrical and mechanical equivalence criteria. The 0.059" (1.50 mm) height difference must be evaluated against PCB layout, enclosure clearances, and any height-sensitive mechanical constraints. If vertical space is unrestricted, this part provides direct substitution with the advantage of active product status and AEC-Q200 certification.

Q: What is the difference between ELXZ630ELL331MK20S and UPW1J331MHD?

A: Both parts match the electrical specifications and lead spacing of the original. ELXZ630ELL331MK20S is manufactured by Chemi-Con (same as the original), is actively produced, and carries automotive qualification. UPW1J331MHD is manufactured by Nichicon, has identical height to the original, but carries "Not For New Designs" status. Selection depends on manufacturer preference, application type, and design phase.

Q: Why does the original part show as obsolete?

A: The LXZ63VB331M12X20LL is classified as obsolete, indicating it is no longer in active production. Equivalent parts from current product lines must be identified for ongoing system support and new designs. Both substitute parts are available in significantly higher inventory quantities.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ELXZ630ELL331MK20S and UPW1J331MHD are RoHS3 compliant, whereas the original LXZ63VB331M12X20LL is RoHS non-compliant. This compliance upgrade is a regulatory requirement for most applications.

Q: Does the ripple current difference between UPW1J331MHD and the original part affect compatibility?

A: UPW1J331MHD has higher ripple current capability at 120 Hz (838.5 mA versus 645 mA). This provides additional thermal margin and does not create compatibility issues. The 100 kHz ripple current is identical across all three parts at 1.29 A.

Q: Which substitute should be selected for automotive applications?

A: ELXZ630ELL331MK20S is the appropriate choice for automotive applications, as it carries AEC-Q200 certification. UPW1J331MHD does not have automotive qualification and is designated "Not For New Designs."

Q: Can these parts be used interchangeably on the same PCB?

A: ELXZ630ELL331MK20S and UPW1J331MHD can be used interchangeably if PCB layout accommodates the height variation. ELXZ630ELL331MK20S is 0.059" (1.50 mm) taller. Both maintain identical lead spacing (0.197" / 5.00 mm) and case diameter (0.492" / 12.50 mm), ensuring footprint compatibility.
