Equivalent & Substitute Parts for 2.5SLE82M

Part Overview

The Rubycon 2.5SLE82M is an 82 µF, 2.5 V aluminum polymer capacitor in the 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part delivers 9 mOhm equivalent series resistance with a 2000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring compact form factors and low impedance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2.5SLE82M is determined by the following critical parameters:

• Capacitance Value: 82 µF (exact match required)
• Package Type: 2917 (7343 Metric) surface mount (exact match required for PCB compatibility)
• ESR: 9 mOhm (exact match required for electrical performance)
• Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Voltage Rating: Rated voltage must equal or exceed the original 2.5 V specification

The Panasonic EEF-SX0G820ER qualifies as a substitute because it maintains identical capacitance, package dimensions, ESR, lifetime rating, and operating temperature range. The rated voltage of 4 V exceeds the original 2.5 V requirement, providing additional design margin without compromising circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-SX0G820ER is a direct substitute for the obsolete Rubycon 2.5SLE82M. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part carries active product status, providing long-term availability and supply chain stability compared to the obsolete original.

The higher voltage rating (4 V versus 2.5 V) and increased ripple current capability (6.3 A versus 3 A at 100 kHz) of the substitute part present no compatibility concerns and offer improved electrical margins for the application. Physical dimensions and mounting characteristics are identical, eliminating PCB redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0G820ER be used as a direct replacement without PCB modifications?

A: Yes. Both parts share identical package dimensions (2917/7343 Metric), surface mount land sizes (0.287" L x 0.169" W), and mounting type. No PCB layout changes are required.

Q: Why does the substitute part have a higher voltage rating?

A: The 4 V rating of the EEF-SX0G820ER exceeds the original 2.5 V specification. This provides additional design margin and is fully compatible with circuits designed for 2.5 V operation. Higher-rated capacitors do not create functional issues in lower-voltage applications.

Q: Are the electrical characteristics equivalent?

A: The critical electrical parameters are identical: 82 µF capacitance, 9 mOhm ESR, 2000-hour lifetime at 105°C, and -55°C to 105°C operating range. The substitute part's higher ripple current rating (6.3 A versus 3 A) represents an improvement.

Q: What is the significance of the obsolete status?

A: The Rubycon 2.5SLE82M is no longer manufactured. The Panasonic EEF-SX0G820ER maintains active product status, ensuring continued availability and manufacturing support.

Q: Are both parts RoHS compliant?

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