LXY63VB47RM8X12LL Equivalent & Substitute Parts

Part Overview

The LXY63VB47RM8X12LL is a 47 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete, indicating discontinuation from active production. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 3000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Due to obsolete status, equivalent and substitute parts from active product lines are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Engineering Selection Recommendations

Primary Recommendation: ELXY630ELL470MH12D

The ELXY630ELL470MH12D is the preferred substitute for the LXY63VB47RM8X12LL. Both parts are manufactured by Chemi-Con and belong to the LXY series. The ELXY630ELL470MH12D maintains active product status, ensuring continued availability and supply chain stability. This part carries ROHS3 compliance and AEC-Q200 automotive qualification, providing enhanced regulatory alignment for new designs. The electrical and mechanical parameters are identical to the main part, with a height difference of 0.059" (1.50 mm) that remains within typical PCB layout tolerances for radial capacitor applications.

Secondary Recommendations: UPJ1J470MPD, UPM1J470MPD, UPW1J470MPD

The Nichicon UPJ, UPM, and UPW series parts are direct electrical and mechanical equivalents. All three parts are classified as "Not For New Designs," indicating they remain available for legacy system support and field replacements but are not recommended for new product development. These parts carry ROHS3 compliance. The UPM1J470MPD includes AEC-Q200 automotive qualification. Height variations range from 0.453" to 0.492", all within acceptable PCB layout margins. Impedance and ripple current specifications differ from the main part but remain within functional equivalence for the specified 47 µF, 63 V application.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing regulatory requirements absent in the obsolete main part. The ELXY630ELL470MH12D and UPM1J470MPD carry AEC-Q200 certification for automotive applications. Selection should account for application-specific compliance requirements and supply chain preferences between Chemi-Con and Nichicon manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the ELXY630ELL470MH12D directly replace the LXY63VB47RM8X12LL without PCB modifications?

A: Yes. The ELXY630ELL470MH12D is mechanically and electrically equivalent. Lead spacing (0.138" / 3.50 mm) and case diameter (0.315" / 8.00 mm) are identical. The height difference of 0.059" (1.50 mm) is within standard PCB layout tolerances for through-hole radial capacitors and does not require PCB redesign.

Q: What is the significance of the "Not For New Designs" status on the Nichicon parts?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and marketing of these series but maintains production for legacy system support and field replacements. These parts remain functionally equivalent and available but should not be specified for new product development. For new designs, the ELXY630ELL470MH12D (active status) is the preferred choice.

Q: Are there differences in ripple current handling between the main part and substitutes?

A: Yes. Ripple current specifications vary across the parts due to different internal construction. The main part specifies 109.6 mA @ 120 Hz and 274 mA @ 100 kHz. The Nichicon UPJ and UPM series specify higher ripple currents (215 mA @ 120 Hz, 365 mA @ 10 kHz), while the UPW series specifies 121.5 mA @ 120 Hz and 405 mA @ 100 kHz. These variations do not affect substitutability for applications designed around the main part's specifications, as all parts meet or exceed the original ripple current requirements.

Q: What is the difference between ROHS3 compliance and the non-compliant status of the main part?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The obsolete LXY63VB47RM8X12LL predates this regulation. All substitute parts are ROHS3 compliant, making them suitable for modern supply chains and regulatory environments.

Q: Does impedance variation affect circuit performance?

A: Impedance differences reflect internal construction variations but do not affect functional substitutability for the specified 47 µF, 63 V application. The main part specifies 470 mOhms; substitutes range from 250 to 470 mOhms. Lower impedance values indicate improved high-frequency performance. Selection should account for specific circuit requirements, but all parts are functionally equivalent for general-purpose applications.

Q: Is AEC-Q200 certification required for my application?

A: AEC-Q200 certification is required only for automotive applications subject to automotive industry standards. The ELXY630ELL470MH12D and UPM1J470MPD carry this certification. For non-automotive applications, AEC-Q200 certification is not necessary, and any of the listed substitutes are acceptable.

Q: Can I use UPW1J470MPD in place of UPJ1J470MPD?

A: Yes. Both are Nichicon parts with identical electrical and mechanical specifications (47 µF, 63 V, ±20%, 3000 Hrs @ 105°C, through-hole radial package). Height difference is 0.039" (1.00 mm), within PCB layout tolerances. Selection between these parts depends on supply availability and inventory management.
