Substitute Part Grouping Explanation

Substitution of the MALREKA00JS368LG0K is determined by strict equivalence across the following parameters:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 100 V (minimum acceptable)
• Tolerance: ±20% (standard for aluminum electrolytic capacitors)
• Package type: Radial, can configuration
• Mounting: Through-hole with 0.295" (7.50mm) lead spacing
• Physical dimensions: 0.630" diameter (16.00mm), height within acceptable mechanical envelope
• Polarization: Polar (unidirectional)

The substitute part 100PX680MEFC16X31.5 from Rubycon meets all core electrical and mechanical parameters. Physical height variation (34.60mm original vs. 33.00mm substitute) remains within acceptable tolerance for standard PCB layouts. Enhanced operating temperature range and extended lifetime rating of the substitute part provide improved performance margins without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 100PX680MEFC16X31.5 from Rubycon is a direct functional equivalent for the obsolete MALREKA00JS368LG0K. Both components maintain identical electrical specifications for capacitance, voltage rating, and tolerance. The substitute part carries active product status with confirmed inventory availability, ensuring long-term supply continuity.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Rubycon substitute provides extended operating temperature range (-55°C to 105°C versus -40°C to 85°C) and equivalent lifetime rating at higher temperature (2000 Hrs @ 105°C), offering improved thermal performance margins. Physical dimensions remain compatible with existing PCB layouts, with the substitute height (33.00mm) being 0.5mm shorter than the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 100PX680MEFC16X31.5 be used as a direct replacement for MALREKA00JS368LG0K?

A: Yes. Both components share identical capacitance (680 µF), voltage rating (100 V), tolerance (±20%), lead spacing (7.50mm), and package configuration (radial, can, through-hole). Physical dimensions are compatible within standard PCB assembly tolerances.

Q: What is the significance of the extended operating temperature range in the substitute part?

A: The Rubycon substitute operates from -55°C to 105°C compared to the original -40°C to 85°C range. This provides wider environmental compatibility and improved reliability margins in temperature-sensitive applications, though both parts meet the same lifetime specification at their respective maximum rated temperatures.

Q: Are there any mechanical considerations when substituting these parts?

A: The substitute part is 0.5mm shorter in seated height (33.00mm vs. 34.60mm). This minor difference is within standard PCB assembly tolerances and does not affect mechanical fit or electrical performance in standard through-hole applications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original MALREKA00JS368LG0K and substitute 100PX680MEFC16X31.5 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the original part listed as obsolete?

A: The MALREKA00JS368LG0K from the Vishay EKA series has reached end-of-life status. The Rubycon PX series substitute maintains equivalent performance with active product status and confirmed ongoing availability.
