Engineering Selection Recommendations

For Direct Replacement (Maintenance/Repair): Select UKA1C682MHD when exact electrical and mechanical compatibility with the original MALREKB05JS468D00K is required. This Nichicon part maintains identical 16 V voltage rating and all dimensional specifications. Although marked "Not For New Designs," it serves as the functional equivalent for existing circuit boards and legacy equipment.

For New Designs and Production: Select ECA-1CHG682 (Panasonic) as the primary choice. This part is active product status, ROHS3 compliant, and matches all critical parameters including 16 V rating and 2000-hour lifetime at 105°C. It provides enhanced ripple current performance at high frequency (2.047 A @ 100 kHz) compared to the original specification.

For Applications Requiring Voltage Margin: Select either 25PX6800MEFC16X31.5 (Rubycon) or EEU-HD1E682 (Panasonic) when circuit design permits higher voltage rating. Both parts are active product status with identical mechanical fit and capacitance. The 25 V rating provides additional safety margin in applications subject to voltage transients or supply variations. EEU-HD1E682 offers superior ripple current performance (2.04 A @ 120 Hz, 2.346 A @ 100 kHz).

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V original? A: Yes. The 25PX6800MEFC16X31.5 and EEU-HD1E682 are electrically and mechanically compatible substitutes with higher voltage rating. Higher voltage rating does not degrade performance in 16 V applications and provides additional safety margin. All other parameters including capacitance, tolerance, dimensions, and lifetime remain identical.

Q: What is the difference between the direct equivalent and upgrade substitutes? A: The UKA1C682MHD is a direct equivalent matching the original 16 V rating. The upgrade substitutes (25PX6800MEFC16X31.5 and EEU-HD1E682) feature 25 V rating instead of 16 V. Selection depends on circuit requirements and design margin preferences.

Q: Are all substitute parts through-hole mounted with identical lead spacing? A: Yes. All substitute parts maintain 0.295" (7.50 mm) lead spacing, 0.630" (16.00 mm) case diameter, and through-hole mounting type. Height varies slightly: UKA1C682MHD is 1.299" (33.00 mm) versus 1.319" (34.60 mm) for others. This minor difference does not affect PCB compatibility.

Q: Which substitute part should I select for new product designs? A: ECA-1CHG682 (Panasonic) is recommended for new designs. It carries active product status, ensuring long-term availability and supply chain stability. It matches all original specifications and provides enhanced high-frequency ripple current performance.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is the significance of "Not For New Designs" status on the UKA1C682MHD? A: This designation indicates the part is available for replacement and maintenance applications but is not recommended for incorporation into new product designs. It remains a valid direct equivalent for legacy equipment repair and existing circuit board replacement.

Q: How do ripple current ratings affect component selection? A: Ripple current rating indicates the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. The original MALREKB05JS468D00K specifies 1.982 A @ 120 Hz. Substitute parts with equal or higher ripple current ratings are suitable. EEU-HD1E682 and ECA-1CHG682 provide higher ripple current performance, offering additional design margin in high-current applications.
