Parameter Comparison

Engineering Selection Recommendations

The E36D501CSS902MFF5U qualifies as a direct electrical and mechanical equivalent to the E36D501CSS902MFF5M. Both components share identical capacitance, voltage rating, tolerance, thermal lifetime rating, operating temperature range, polarization, package configuration, and mechanical dimensions.

Key Selection Factors:

1. Product Status: The E36D501CSS902MFF5U maintains active production status, whereas the E36D501CSS902MFF5M is obsolete. Selection of the active part ensures long-term supply chain availability and reduces procurement risk.

2. Compliance Enhancement: The E36D501CSS902MFF5U carries ROHS3 compliance, representing a higher compliance standard than the RoHS Compliant designation of the main part. This upgrade does not introduce incompatibility and provides enhanced regulatory alignment.

3. Inventory Availability: The substitute part demonstrates higher current inventory levels (833 Pcs versus 722 Pcs), supporting immediate procurement requirements.

4. Electrical Performance: All electrical parameters remain identical, ensuring equivalent circuit performance, energy storage capacity, and thermal behavior within the specified operating envelope.

5. Mechanical Compatibility: Screw terminal configuration, lead spacing, can diameter, and seated height are identical, permitting direct board-level substitution without layout modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the E36D501CSS902MFF5U be used as a direct replacement for the E36D501CSS902MFF5M in existing designs?

A: Yes. The E36D501CSS902MFF5U is electrically and mechanically equivalent to the E36D501CSS902MFF5M. All critical parameters—capacitance, voltage rating, tolerance, thermal lifetime, operating temperature range, and physical dimensions—are identical. The substitute part may be installed without circuit modification or board redesign.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents a more recent compliance standard with expanded substance restrictions compared to the original RoHS Compliant designation. The E36D501CSS902MFF5U's ROHS3 compliance provides enhanced regulatory alignment and does not introduce incompatibility with designs specified for RoHS Compliant components.

Q: Are the screw terminal configurations identical between the two parts?

A: Yes. Both the E36D501CSS902MFF5M and E36D501CSS902MFF5U feature radial, can-mounted screw terminals with identical lead spacing of 1.240" (31.50 mm). Terminal compatibility is confirmed.

Q: Do the physical dimensions permit interchangeable mounting?

A: Yes. Both parts share identical can diameter (3.500" / 88.90 mm) and maximum seated height (6.102" / 155.00 mm). Chassis-mount installations accommodate both components without mechanical modification.

Q: Why is the E36D501CSS902MFF5M classified as obsolete?

A: Obsolete status indicates the part has been discontinued from active manufacturing. The E36D501CSS902MFF5U represents the active production equivalent, ensuring continued supply availability and design continuity.

Q: Is inventory availability a factor in component selection?

A: Inventory levels reflect current stock status. The E36D501CSS902MFF5U demonstrates higher availability (833 Pcs) compared to the main part (722 Pcs), supporting procurement timelines and reducing lead-time risk.

Q: Are there any thermal performance differences between the two parts?
