Engineering Selection Recommendations

For Direct Replacement in Existing Designs: UKA1C682MHD (Nichicon) provides the closest functional match with identical electrical specifications and mechanical form factor. However, this part carries "Not For New Designs" status, limiting its use to legacy system maintenance.

For New Designs and Long-Term Availability: ECA-1CHG682 (Panasonic) is the preferred selection, offering active product status with matching 16 V rating, identical capacitance, and full mechanical compatibility. This part ensures supply chain continuity and design longevity.

For Applications Requiring Voltage Margin: 25PX6800MEFC16X31.5 (Rubycon) and EEU-HD1E682 (Panasonic) both provide 25 V ratings while maintaining identical mechanical dimensions and capacitance. These upgrades are suitable for designs where increased voltage headroom is beneficial. Both parts carry active product status.

All substitute parts maintain ROHS3 compliance and are rated for the same operating temperature range (-55°C to 105°C) and lifetime specification (2000 Hrs @ 105°C) as the original component.

Frequently Asked Questions (FAQ)

Q: Can UKA1C682MHD be used as a direct replacement for MALREKB00JS468D00K? A: Yes, UKA1C682MHD is electrically and mechanically equivalent with matching 6800 µF capacitance, 16 V rating, ±20% tolerance, and identical package dimensions. However, its "Not For New Designs" status restricts use to legacy system support.

Q: What is the difference between the 16 V and 25 V substitute options? A: The 25 V rated parts (25PX6800MEFC16X31.5 and EEU-HD1E682) provide higher voltage headroom while maintaining identical mechanical form factor and capacitance. These are suitable for applications where voltage margin is desired. The 16 V rated parts (UKA1C682MHD and ECA-1CHG682) match the original specification exactly.

Q: Are all substitute parts mechanically compatible with the original PCB layout? A: All substitute parts share the same lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), and mounting type (through hole radial). Height variations are minimal (33.00 mm to 34.60 mm), ensuring compatibility within standard PCB design tolerances.

Q: Which substitute part is recommended for new product designs? A: ECA-1CHG682 (Panasonic) is recommended for new designs due to its active product status, ensuring long-term availability and supply chain stability. For applications requiring voltage margin, 25PX6800MEFC16X31.5 (Rubycon) or EEU-HD1E682 (Panasonic) are suitable alternatives.

Q: Do all substitute parts meet the same compliance requirements? A: Yes, all substitute parts are ROHS3 compliant and REACH unaffected, matching the original component's regulatory status. All parts carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the ripple current capability of each substitute? A: UKA1C682MHD provides 1.78 A @ 120 Hz and 2.047 A @ 10 kHz. EEU-HD1E682 provides 2.04 A @ 120 Hz and 2.346 A @ 100 kHz. ECA-1CHG682 provides 1.78 A @ 120 Hz and 2.047 A @ 100 kHz. The original MALREKB00JS468D00K specifies 1.982 A @ 120 Hz.
