Engineering Selection Recommendations

For Direct Replacement (Same Voltage - 160 V):

UCA2C470MHD is the direct equivalent from Nichicon's active product line. It maintains identical electrical specifications (47 µF, ±20%, 160 V) and mechanical dimensions while offering extended lifetime (12000 Hrs @ 105°C versus 5000 Hrs). This part is ROHS3 compliant and suitable for applications requiring no voltage margin increase.

For Upgraded Performance (Higher Voltage Ratings):

Upgrade substitutes provide higher voltage ratings (200 V or 250 V) while maintaining the same capacitance and mechanical footprint. These parts are appropriate for applications where:

Circuit voltage margins require additional headroom
Extended component lifetime is beneficial
Active product availability is prioritized over exact voltage matching

Nichicon UCS and UCY series parts offer ROHS3 compliance and extended operating temperature ranges (-40°C to 105°C). Rubycon BXC and CFX series parts provide alternative sourcing with comparable specifications.

Product Status Consideration:

All recommended substitutes are classified as Active products, ensuring long-term availability and supply chain continuity. The original UPB2C470MHD and UCA2C470MHD are both obsolete; therefore, migration to active product lines (UCS, UCY, or equivalent third-party alternatives) is recommended for new designs and production planning.

Frequently Asked Questions (FAQ)

Q: Can UCS2D470MHD (200 V) be used in place of UPB2C470MHD (160 V)?

A: Yes. The UCS2D470MHD is a direct upgrade substitute. Higher voltage rating provides additional safety margin in the circuit. All other electrical and mechanical parameters are compatible. The part is active and ROHS3 compliant.

Q: What is the difference between Nichicon UCY and UCS series?

A: Both series maintain identical capacitance (47 µF), tolerance (±20%), and mechanical dimensions. The UCY series offers extended lifetime (12000 Hrs @ 105°C) compared to UCS (10000 Hrs @ 105°C). Both support expanded operating temperature range (-40°C to 105°C).

Q: Why does EKXG251ELL470MK20S have a different height (0.787" vs 0.846")?

A: EKXG251ELL470MK20S from Chemi-Con has a reduced seated height of 0.787" (20.00mm) compared to the standard 0.846" (21.50mm). This part is mechanically compatible if vertical space constraints allow the shorter dimension. All other parameters match the substitution criteria.

Q: Are Rubycon BXC and CFX series parts compatible with the original UPB2C470MHD?

A: Yes. Rubycon BXC and CFX series parts (200BXC47MEFC12.5X20, 250BXC47MEFC12.5X20, 200CFX47MEFC12.5X20, 250CFX47M12.5X20) maintain the required capacitance, tolerance, lead spacing, and mounting type. Height variation (0.866" vs 0.846") is within typical mechanical envelope tolerances for radial can packages. All parts are ROHS3 compliant and active products.

Q: Which substitute offers the longest lifetime at 105°C?

A: Nichicon UCY2D470MHD3 and UCY2E470MHD3, along with Rubycon 200BXC47MEFC12.5X20 and 250BXC47MEFC12.5X20, all offer 12000 hours lifetime at 105°C, the maximum among available substitutes.

Q: Is the UCA2C470MHD still available if it is marked obsolete?

A: UCA2C470MHD is classified as obsolete. For new production and long-term supply assurance, active product substitutes (UCS, UCY, or equivalent third-party series) are recommended. Inventory availability may vary by distributor.
