Key Parameters

Substitute Part Grouping Explanation

Substitution of the 36DX403G050CF2A is determined by the following critical parameters:

• Capacitance Range: The substitute must accommodate the original 40000 µF specification within acceptable tolerance limits. The MAL210118473E3 provides 47000 µF, which falls within the tolerance envelope when considering the original part's -10%, +75% tolerance specification.
• Voltage Rating: The substitute voltage rating must equal or exceed the original 50 V requirement. The MAL210118473E3 is rated at 63 V, providing adequate voltage margin.
• Package Configuration: Both parts utilize radial, can-style screw terminals with chassis-mount configuration, ensuring mechanical and electrical compatibility.
• Operating Temperature Range: Both parts operate across -40°C to 85°C, maintaining thermal compatibility.
• Polarization: Both components are polar aluminum electrolytic capacitors.
• Compliance: Both parts meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The MAL210118473E3 is a suitable substitute for the obsolete 36DX403G050CF2A based on the following factors:

• Product Status: The substitute is classified as active, ensuring continued availability and supply chain stability compared to the obsolete original part.
• Regulatory Compliance: Both components meet ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment across manufacturing and deployment environments.
• Electrical Compatibility: The substitute's 63 V rating exceeds the original 50 V requirement, and the 47000 µF capacitance is within acceptable operating parameters for general-purpose applications.
• Mechanical Fit: Lead spacing and mounting configuration are compatible, with dimensional differences that do not preclude installation in existing chassis-mount applications.
• Thermal Performance: The substitute's 15000-hour lifetime at 85°C significantly exceeds the original 1000-hour specification, providing enhanced reliability.

Frequently Asked Questions (FAQ)

Q: Can the MAL210118473E3 directly replace the 36DX403G050CF2A in existing designs?

A: Yes. Both components share identical package configurations (radial, can-style screw terminals), mounting types (chassis mount), and operating temperature ranges (-40°C to 85°C). Lead spacing and dimensional differences are minimal and do not prevent installation.

Q: What is the capacitance difference between the original and substitute parts?

A: The original part is 40000 µF; the substitute is 47000 µF. This 7000 µF increase falls within acceptable tolerance limits for general-purpose applications and does not compromise circuit functionality.

Q: Does the higher voltage rating of the substitute affect compatibility?

A: No. The substitute's 63 V rating exceeds the original 50 V requirement, providing additional voltage margin. Higher voltage ratings do not negatively impact circuit performance in applications designed for lower voltages.

Q: Are there any dimensional constraints when installing the MAL210118473E3?

A: The substitute is shorter (4.165" vs. 5.752" seated height) and slightly smaller in diameter (2.559" vs. 2.579"). These differences typically provide installation advantages in space-constrained applications. Lead spacing is nearly identical (1.122" vs. 1.126").

Q: What compliance certifications apply to both parts?

A: Both the 36DX403G050CF2A and MAL210118473E3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and deployment.
