Engineering Selection Recommendations

ELXZ630ELL152MM35S (Chemi-Con LXZ Series)

This substitute is the primary equivalent for the LXZ63VB152M18X35LL. Both components are from the same manufacturer and series, ensuring design continuity. The ELXZ630ELL152MM35S is currently in active production status, providing long-term availability. It carries ROHS3 compliance and AEC-Q200 automotive qualification, exceeding the original part's compliance profile. The height difference of 0.059" (1.50 mm) is within typical PCB clearance tolerances for through-hole radial capacitors. This part is recommended for new designs and ongoing production requiring direct replacement.

UPW1J152MHD (Nichicon UPW Series)

This substitute provides functional equivalence with identical electrical parameters. The Nichicon UPW1J152MHD offers superior ripple current capability at low frequency (2.635 A @ 120 Hz versus 1.86 A), providing additional thermal margin in ripple-current-limited applications. The part carries ROHS3 compliance. Product status is listed as Not For New Designs, indicating this component is in mature production but not recommended for new circuit designs. Height is 1.398" (35.50 mm), representing a 0.020" (0.50 mm) increase from the original. This part is suitable for legacy system support and field replacements where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can ELXZ630ELL152MM35S be used as a direct replacement for LXZ63VB152M18X35LL?

A: Yes. Both components share identical electrical specifications: 1500 µF, 63 V, ±20% tolerance, 8000 Hrs @ 105°C, and identical mechanical lead spacing and case diameter. The height difference of 1.50 mm is within standard PCB clearance for radial through-hole capacitors. Verify PCB layout clearance before substitution.

Q: What is the height difference between the original part and substitutes?

A: The LXZ63VB152M18X35LL has a maximum seated height of 1.378" (35.00 mm). The ELXZ630ELL152MM35S measures 1.437" (36.50 mm), and the UPW1J152MHD measures 1.398" (35.50 mm). Both substitutes exceed the original height by less than 2 mm, which is acceptable for most through-hole applications. Confirm PCB component clearance and enclosure constraints before implementation.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ELXZ630ELL152MM35S and UPW1J152MHD are ROHS3 compliant, whereas the original LXZ63VB152M18X35LL is RoHS non-compliant. This represents an improvement in environmental compliance for replacement applications.

Q: What is the difference in ripple current ratings?

A: The LXZ63VB152M18X35LL and ELXZ630ELL152MM35S both support 1.86 A @ 120 Hz and 3.1 A @ 100 kHz. The UPW1J152MHD supports 2.635 A @ 120 Hz and 3.1 A @ 100 kHz. The higher low-frequency ripple current in the Nichicon part provides additional thermal headroom in applications with significant 120 Hz ripple content.

Q: Why is the original part listed as obsolete?

A: The LXZ63VB152M18X35LL is obsolete and no longer in production. The ELXZ630ELL152MM35S is the active production equivalent from the same manufacturer and series, recommended for all new procurement and design activities.

Q: Can UPW1J152MHD be used for new designs?

A: The UPW1J152MHD is listed as Not For New Designs. This part is suitable for legacy system support, field replacements, and maintenance applications where existing inventory is available. For new circuit designs, use ELXZ630ELL152MM35S.

Q: Are lead spacing and case diameter identical across all three parts?

A: Yes. All three components share identical lead spacing of 0.295" (7.50 mm) and case diameter of 0.709" (18.00 mm), ensuring PCB footprint compatibility.
