MALREKA05JS510D00K Equivalent & Substitute Parts

Part Overview

The MALREKA05JS510D00K is a 10000 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Vishay Beyschlag/Draloric/BC Components from the EKA series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges.

Substitute Part Grouping Explanation

Substitution for the MALREKA05JS510D00K is determined by strict equivalence in the following parameters:

Capacitance: 10000 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50mm) (exact match required)
Diameter: 0.630" (16.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Differences in operating temperature range, lifetime rating, and ripple current specifications do not disqualify parts from functional equivalence in applications where the original part's performance envelope is not exceeded.

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance, providing long-term procurement viability compared to the obsolete MALREKA05JS510D00K.

16PX10000MEFC16X31.5 (Rubycon PX Series): This upgrade substitute offers extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C). Height is 0.020" shorter than the original part. Suitable for applications requiring enhanced thermal performance.

EEU-HD1C103 (Panasonic HD Series): This upgrade substitute provides extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C). Physical dimensions match the original part exactly. Suitable for applications requiring enhanced thermal performance.

16PK10000MEFC16X31.5 (Rubycon PK Series): This parametric equivalent maintains the original operating temperature range (-40°C ~ 85°C) and lifetime rating (2000 Hrs @ 85°C). Physical dimensions match the original part exactly. Suitable for direct replacement in applications with matching thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 16PX10000MEFC16X31.5 or EEU-HD1C103 in place of MALREKA05JS510D00K?

A: Yes. Both parts meet all core electrical and mechanical substitution criteria: 10000 µF capacitance, 16 V rating, ±20% tolerance, identical package type, lead spacing, and diameter. Both are active products with ROHS3 compliance. The extended temperature range and higher temperature lifetime rating represent performance improvements over the obsolete original part.

Q: What is the difference between 16PX10000MEFC16X31.5 and 16PK10000MEFC16X31.5?

A: Both are Rubycon radial aluminum electrolytic capacitors with identical electrical ratings. The PX series (16PX10000MEFC16X31.5) operates across -55°C ~ 105°C with 2000 Hrs @ 105°C lifetime. The PK series (16PK10000MEFC16X31.5) operates across -40°C ~ 85°C with 2000 Hrs @ 85°C lifetime. Select based on your application's thermal requirements.

Q: Will the height difference of 16PX10000MEFC16X31.5 affect PCB layout?

A: The 16PX10000MEFC16X31.5 is 0.020" (0.50mm) shorter than the original part. This minor difference is unlikely to cause PCB layout issues in most applications. Verify clearance in your specific design if height-constrained space is a concern.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MALREKA05JS510D00K, 16PX10000MEFC16X31.5, EEU-HD1C103, and 16PK10000MEFC16X31.5 are all ROHS3 compliant.

Q: Which substitute should I choose for a new design?

A: For new designs, either 16PX10000MEFC16X31.5 or EEU-HD1C103 are recommended as they are active products with extended thermal performance. Choose based on manufacturer preference and availability. For applications with strict thermal constraints matching the original part, 16PK10000MEFC16X31.5 provides parametric equivalence.
