Substitute Part Grouping Explanation

Substitution of the LXY63VB82RM8X20LL is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Capacitance: 82 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (3.50 mm) (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)

Secondary Compatibility Parameters:

Ripple Current ratings (120 Hz and 100 kHz)
Impedance (210 mOhms)
Physical dimensions (diameter and height)

The substitute part ELXY630ELL820MH20D meets all primary substitution criteria and maintains compatibility across secondary parameters. Differences in product status, RoHS compliance, and application classification do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

ELXY630ELL820MH20D as Primary Substitute:

The ELXY630ELL820MH20D is the direct equivalent for the obsolete LXY63VB82RM8X20LL. Both components are manufactured by Chemi-Con within the LXY series and share identical electrical specifications across capacitance, voltage rating, tolerance, temperature range, and ripple current ratings.

The substitute part offers the following advantages:

Active product status ensures ongoing availability and supply chain continuity
ROHS3 compliance meets current regulatory requirements
AEC-Q200 automotive qualification provides additional reliability documentation
Identical electrical performance across all specified parameters
Physical dimensions are compatible with existing PCB layouts (height difference of 1.5 mm is within typical component tolerance and board clearance margins)

The height difference (0.846" vs. 0.787") does not affect electrical interchangeability and is accommodated within standard PCB design clearances for radial through-hole components.

Frequently Asked Questions (FAQ)

Q: Can ELXY630ELL820MH20D be used as a direct replacement for LXY63VB82RM8X20LL?

A: Yes. Both components are electrically and mechanically equivalent. They share identical capacitance (82 µF), voltage rating (63 V), tolerance (±20%), temperature range (-55°C ~ 105°C), and ripple current specifications. Lead spacing and package type are identical, enabling direct PCB substitution.

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

A: The substitute part is 0.846" (21.50 mm) tall compared to the original 0.787" (20.00 mm). This 1.5 mm difference is within standard component tolerance ranges and does not affect PCB layout compatibility for through-hole radial capacitors. Existing board designs accommodate this variation.

Q: Why is the substitute part listed as Active while the original is Obsolete?

A: The LXY63VB82RM8X20LL has been discontinued by Chemi-Con. The ELXY630ELL820MH20D remains in active production, ensuring availability for replacement, repair, and new applications requiring this specification.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: No. ROHS3 compliance is a manufacturing and environmental standard that does not alter electrical or mechanical performance. The substitute meets current regulatory requirements while maintaining full compatibility with the original specification.

Q: Are there any application restrictions for the substitute part?

A: The substitute is qualified for automotive applications (AEC-Q200), which encompasses the general-purpose classification of the original part. It is suitable for all applications where the original LXY63VB82RM8X20LL was specified.

Q: What parameters must remain identical for substitution to be valid?

A: Capacitance, voltage rating, tolerance, polarization, operating temperature range, lead spacing, and package type must be identical. The substitute ELXY630ELL820MH20D meets all these requirements.
