Substitute Part Grouping Explanation

Substitution of the MALREKB00JS368L00K 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 window)
• Operating temperature range: -55°C ~ 105°C (thermal compatibility)
• Lifetime specification: 2000 Hrs @ 105°C (reliability requirement)
• Package type: Radial, Can (mechanical fit)
• Lead spacing: 0.295" (7.50mm) (PCB compatibility)
• Physical dimensions: 0.630" Dia (16.00mm) (form factor)
• Mounting type: Through Hole (assembly method)
• Polarization: Polar (circuit requirement)

The substitute part 100PX680MEFC16X31.5 from Rubycon meets all critical substitution criteria and maintains functional equivalence for the specified application.

Parameter Comparison

Engineering Selection Recommendations

The Rubycon 100PX680MEFC16X31.5 is a direct functional equivalent to the obsolete Vishay MALREKB00JS368L00K. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part is classified as active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Physical dimensions are compatible within acceptable tolerances for through-hole PCB assembly. The seated height difference of 0.020" (0.50mm) is negligible for standard circuit board layouts. Electrical parameters—capacitance, voltage rating, tolerance, operating temperature range, and lifetime specification—are identical, confirming direct substitution capability.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 100PX680MEFC16X31.5 be used as a direct replacement for the Vishay MALREKB00JS368L00K?

A: Yes. Both components share identical electrical specifications (680 µF, ±20%, 100 V, 2000 Hrs @ 105°C) and mechanical compatibility (radial can package, 7.50mm lead spacing, 16.00mm diameter). The substitute part is functionally equivalent for all general-purpose applications.

Q: Are there any physical dimension concerns when substituting?

A: The seated height differs by 0.020" (0.50mm), with the Rubycon part measuring 1.299" versus the Vishay part at 1.319". This variance is within standard PCB clearance tolerances and does not affect assembly or performance in typical circuit designs.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the primary reason for substitution?

A: The Vishay MALREKB00JS368L00K is classified as obsolete. The Rubycon substitute maintains active product status, ensuring reliable supply chain access and long-term availability for production and design support.

Q: Are the ripple current specifications equivalent?

A: The original part specifies 1.344 A @ 120 Hz. The substitute provides 900 mA @ 120 Hz and 1.08 A @ 10 kHz. For applications requiring specific ripple current performance, circuit-level analysis is necessary to confirm suitability based on actual operating conditions.
