MALREKB00JS468DG0K Equivalent & Substitute Parts

Part Overview

The MALREKB00JS468DG0K is a 6800 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Vishay Beyschlag/Draloric/BC Components from the EKB series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design considerations. The part features a 60 mOhm equivalent series resistance at 120 Hz and is rated for 2000 hours at 105°C operating temperature.

Substitute Part Grouping Explanation

Substitution for the MALREKB00JS468DG0K is determined by the following critical parameters: capacitance value (6800 µF), voltage rating, tolerance (±20%), physical dimensions (lead spacing, case diameter, height), mounting type (through hole radial), and compliance certifications (ROHS3).

The substitute parts are grouped into three categories:

Direct Equivalent (Same Voltage Rating): UKA1C682MHD and ECA-1CHG682 maintain the 16 V voltage rating, matching the original specification exactly.

Upgrade Substitutes (Higher Voltage Rating): 25PX6800MEFC16X31.5 and EEU-HD1E682 feature a 25 V voltage rating, providing enhanced voltage margin while maintaining identical capacitance, tolerance, physical dimensions, and thermal characteristics. These parts are electrically compatible in applications where the original 16 V rating is used, as they can safely operate at lower voltages.

All substitute parts share the same capacitance (6800 µF), tolerance (±20%), operating temperature range (-55°C to 105°C), thermal lifetime (2000 Hrs @ 105°C), lead spacing (7.50 mm), case diameter (16.00 mm), height (34.60 mm), mounting type (through hole), package type (radial, can), and ROHS3 compliance.

Engineering Selection Recommendations

For replacement of the obsolete MALREKB00JS468DG0K, the following selection criteria apply:

Direct Replacement (Same Voltage): ECA-1CHG682 (Panasonic, Active status) is the preferred direct equivalent, maintaining the 16 V voltage specification with active product status and full ROHS3 compliance. UKA1C682MHD (Nichicon) provides an alternative direct equivalent but carries "Not For New Designs" status.

Upgrade Replacement (Higher Voltage): 25PX6800MEFC16X31.5 (Rubycon, Active status) and EEU-HD1E682 (Panasonic, Active status) both offer 25 V ratings with active product status. These parts are suitable for applications where voltage margin enhancement is acceptable and provide long-term design continuity.

All substitute parts maintain ROHS3 compliance and thermal specifications identical to the original component. Selection should prioritize parts with active product status for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of a 16 V rated capacitor?

A: Yes. A 25 V rated capacitor can safely operate at 16 V or lower. The voltage rating indicates the maximum voltage the capacitor can withstand; operating at a lower voltage than the rating does not compromise functionality or reliability.

Q: Are all substitute parts physically identical to the original MALREKB00JS468DG0K?

A: All substitute parts share the same lead spacing (7.50 mm), case diameter (16.00 mm), and mounting type (through hole radial). Height varies minimally: UKA1C682MHD is 33.00 mm versus 34.60 mm for the original and other substitutes. This 0.5 mm difference is within standard PCB layout tolerances for through-hole components.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (UKA1C682MHD, ECA-1CHG682) maintain the 16 V voltage rating. Upgrade substitutes (25PX6800MEFC16X31.5, EEU-HD1E682) feature 25 V ratings, providing additional voltage headroom. Both categories are electrically compatible with the original 16 V application.

Q: Which substitute should I choose for new designs?

A: For new designs, select from parts with active product status: 25PX6800MEFC16X31.5 (Rubycon) or EEU-HD1E682 (Panasonic). Both offer long-term availability and full ROHS3 compliance. ECA-1CHG682 (Panasonic) is also active and provides direct 16 V equivalence if voltage upgrade is not required.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original MALREKB00JS468DG0K.

Q: What does "Not For New Designs" status mean?

A: "Not For New Designs" indicates the manufacturer no longer recommends the part for new product development, though existing inventory may remain available. For new designs, prioritize parts with active status.
