Key Parameters

Substitute Part Grouping Explanation

Substitution of the MALREKB00JS368LG0K is determined by strict equivalence across the following critical parameters:

• Capacitance value: 680 µF (exact match required)
• Voltage rating: 100 V (minimum acceptable)
• Tolerance: ±20% (electrical performance band)
• Operating temperature range: -55°C ~ 105°C (thermal compatibility)
• Lifetime specification: 2000 Hrs @ 105°C (reliability requirement)
• Polarization: Polar (circuit function requirement)
• Lead spacing: 0.295" (7.50mm) (PCB layout compatibility)
• Physical dimensions: 0.630" Dia (16.00mm) (mechanical fit)
• Mounting type: Through Hole (assembly process compatibility)
• Package type: Radial, Can (form factor requirement)

The substitute part 100PX680MEFC16X31.5 from Rubycon meets all critical electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 100PX680MEFC16X31.5 from Rubycon is a direct functional equivalent to the obsolete MALREKB00JS368LG0K. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Rubycon part carries active product status, ensuring ongoing availability and supply chain stability compared to the obsolete Vishay component.

Physical dimensions are compatible with existing PCB layouts, with the Rubycon part measuring 0.20" (0.50mm) shorter in seated height, which presents no mechanical interference risk in standard through-hole applications. Electrical performance is equivalent across all specified parameters, including capacitance, voltage rating, tolerance, and thermal lifetime specifications.

Frequently Asked Questions (FAQ)

Q: Can the 100PX680MEFC16X31.5 be used as a direct replacement for the MALREKB00JS368LG0K?

A: Yes. Both components share identical electrical specifications (680 µF, ±20%, 100 V, 2000 Hrs @ 105°C) and mechanical compatibility (lead spacing, diameter, through-hole mounting). The 0.20" height difference does not affect PCB assembly or circuit function.

Q: What is the primary reason for substitution?

A: The MALREKB00JS368LG0K is classified as obsolete. The Rubycon 100PX680MEFC16X31.5 maintains active product status, ensuring continued availability and manufacturing support.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: Does the height difference affect PCB design?

A: No. The Rubycon part is 0.20" (0.50mm) shorter, which is within standard PCB clearance tolerances and does not require design modification.

Q: What parameters must remain constant for substitution?

A: Capacitance (680 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), thermal lifetime (2000 Hrs @ 105°C), lead spacing (7.50mm), diameter (16.00mm), and mounting type (through-hole radial can) must all match exactly.
