Engineering Selection Recommendations

EKZE101ELL470MJC5S (Chemi-Con KZE Series) - Upgrade Substitute:

This part is classified as active product status, ensuring long-term availability and supply chain stability. The 100 V voltage rating provides increased design margin over the original 63 V specification. Physical height increases from 12.00 mm to 14.00 mm; PCB layout verification is required to confirm clearance in the mounting area. Ripple current capacity increases to 192 mA @ 120 Hz and 480 mA @ 100 kHz, supporting higher current applications. RoHS3 compliance and identical lead spacing (5.00 mm) ensure direct PCB compatibility. This substitute is suitable for new production designs and replacement applications where increased voltage margin and ripple current handling are beneficial.

UHE2A470MPD (Nichicon UHE Series) - Similar Substitute:

This part carries product status designation "Not For New Designs," indicating it remains available for legacy system maintenance and repair but should not be selected for new development. The 100 V voltage rating matches the Chemi-Con alternative. Operational lifetime extends to 7000 hours @ 105°C, exceeding both the original part and the Chemi-Con substitute. Physical height of 12.50 mm remains within typical PCB clearance tolerances. Ripple current capacity reaches 227.5 mA @ 120 Hz and 325 mA @ 100 kHz. RoHS3 compliance is confirmed. REACH status indicates this part is affected by REACH regulations, requiring compliance verification for specific end-use applications. This substitute is appropriate for field replacement and maintenance of existing systems.

Selection Criteria Summary:

For new production: Select EKZE101ELL470MJC5S (active status, higher ripple current)
For legacy system maintenance: UHE2A470MPD remains available with extended lifetime rating
Both substitutes provide voltage margin improvement and maintain electrical/mechanical compatibility
PCB layout review required for EKZE101ELL470MJC5S due to 2.00 mm height increase

Frequently Asked Questions (FAQ)

Q: Can the SXR470M063ST be directly replaced with EKZE101ELL470MJC5S without PCB modification?

A: Direct replacement is possible with one consideration: the EKZE101ELL470MJC5S has a maximum seated height of 14.00 mm compared to 12.00 mm for the original part. Lead spacing remains identical at 5.00 mm. PCB layout must be verified to confirm adequate clearance above the capacitor location. If clearance exists, no PCB modification is required.

Q: Why do the substitute parts have 100 V ratings instead of 63 V?

A: Both identified substitutes are rated for 100 V operation. This higher voltage rating provides increased design margin and does not create incompatibility. A 100 V capacitor operates safely in a 63 V circuit. The higher rating may improve reliability and extend component lifetime in the application.

Q: Are there any electrical performance differences between the three parts?

A: Yes. Ripple current capacity differs: the original SXR470M063ST handles 140.3 mA @ 120 Hz, while EKZE101ELL470MJC5S handles 192 mA and UHE2A470MPD handles 227.5 mA. For applications with high AC ripple current, the substitutes provide superior performance. Operational lifetime also differs: original 4000 hours, EKZE101ELL470MJC5S 4000 hours, and UHE2A470MPD 7000 hours @ 105°C.

Q: What does "Not For New Designs" mean for the UHE2A470MPD?

A: This designation indicates the part is in mature/legacy status. Nichicon continues to manufacture and supply this component for replacement and maintenance of existing systems. However, for new product development, Chemi-Con EKZE101ELL470MJC5S (active status) is the recommended choice to ensure long-term availability and support.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both EKZE101ELL470MJC5S and UHE2A470MPD carry RoHS3 compliance certification, matching the original SXR470M063ST. This ensures compliance with environmental and regulatory requirements for electronic component manufacturing and disposal.

Q: What is the difference between lead spacing and physical dimensions?

A: Lead spacing (0.197" or 5.00 mm) refers to the distance between the two radial leads and determines PCB hole alignment. Physical dimensions (can diameter 10.00 mm, height 12.00-14.00 mm) refer to the component body size and determine clearance requirements above the PCB. Both must be verified for compatibility.

Q: Can capacitance tolerance affect substitution?

A: All three parts share ±20% tolerance. Tighter tolerance specifications (such as ±10%) would also be acceptable substitutes. However, looser tolerances would not meet the substitution criteria. The ±20% tolerance is a critical parameter that must be matched or improved.

Q: Is the REACH status of UHE2A470MPD a concern?

A: REACH status "Affected" indicates the part contains substances regulated under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals). This requires compliance verification based on the specific end-use application and geographic market. For applications subject to REACH regulations, documentation and substance declarations must be obtained from the manufacturer.
