Key Parameters

Substitute Part Grouping Explanation

Substitution of the EDLSD334V5R5C is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value: 330 mF (exact match required)
• Voltage rating: 5.5 V (exact match required)
• Operating temperature range: -25°C to 70°C (minimum requirement)
• Lifetime specification: 1000 Hrs @ 70°C (minimum requirement)

Mechanical Compatibility:

• Mounting type: Through Hole (required for PCB integration)
• Package configuration: Axial, Can - Vertical (required for form factor)
• Lead spacing: 0.197" (5.00 mm) (required for footprint compatibility)
• Termination: PC Pins (required for soldering compatibility)

Regulatory Compliance:

• RoHS3 compliance (required for environmental standards)

The substitute part KR-5R5V334-R from Eaton - Electronics Division meets all critical electrical and mechanical parameters while maintaining regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The KR-5R5V334-R from Eaton - Electronics Division is a direct electrical substitute for the obsolete EDLSD334V5R5C. Both components are ROHS3 compliant and share identical electrical specifications for capacitance, voltage rating, and thermal lifetime.

Mechanical Considerations: The substitute part exhibits larger physical dimensions (0.453" diameter vs. 0.413", and 0.492" height vs. 0.453"). PCB layout verification is required to confirm clearance in the mounting area. Lead spacing remains identical at 0.197" (5.00 mm), ensuring footprint compatibility.

Electrical Performance: The KR-5R5V334-R demonstrates superior ESR performance at 50 Ohm @ 1 kHz compared to the original 75 Ohm specification, resulting in lower power dissipation and improved efficiency in energy storage applications.

Availability and Status: The substitute part is currently in active production status with 5705 pieces available as new original stock, providing long-term procurement security compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the KR-5R5V334-R be used as a direct replacement for EDLSD334V5R5C?

A: Yes, the KR-5R5V334-R is electrically compatible as a direct substitute. Both components share identical capacitance (330 mF), voltage rating (5.5 V), lead spacing (0.197"), and thermal specifications (1000 Hrs @ 70°C). Physical dimensions differ slightly; PCB clearance must be verified before implementation.

Q: What is the significance of the ESR difference between the two parts?

A: The KR-5R5V334-R has lower ESR (50 Ohm vs. 75 Ohm @ 1 kHz). Lower ESR reduces resistive heating during charge/discharge cycles, improving overall system efficiency and thermal performance. This represents an improvement over the original specification.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant. The KR-5R5V334-R includes REACH Unaffected status documentation. No compliance barriers exist for substitution.

Q: What physical space considerations apply?

A: The substitute part is larger in both diameter (0.453" vs. 0.413") and height (0.492" vs. 0.453"). Verify PCB layout clearance around the mounting location. Lead spacing and termination type remain identical, ensuring electrical compatibility.

Q: Why is the original part obsolete?

A: The EDLSD334V5R5C is classified as obsolete by the manufacturer. The KR-5R5V334-R from Eaton represents the active equivalent for continued system support and new procurement.
