Substitute Part Grouping Explanation

Substitution eligibility for the Rubycon 2.5SLG100M is determined by the following critical parameters:

• Capacitance Value: Must be 100 µF (exact match required)
• Tolerance: Must be ±20% (exact match required)
• Package / Case: Must be 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Must be Surface Mount (exact match required)
• Type: Must be Polymer (exact match required for electrical characteristics)
• Operating Temperature Range: Must support -55°C ~ 105°C minimum
• RoHS Status: Must maintain ROHS3 Compliance

The Panasonic EEF-CT0J101R qualifies as a substitute based on matching capacitance, tolerance, package, mounting type, polymer construction, operating temperature range, and RoHS3 compliance. Voltage rating and ESR differences are acceptable within the substitution framework, as the substitute's higher voltage rating (6.3 V vs. 2.5 V) provides backward compatibility, and ESR variance (15 mOhm vs. 9 mOhm) remains within acceptable operational parameters for general purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CT0J101R is suitable for direct substitution of the obsolete Rubycon 2.5SLG100M. The substitute maintains active product status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and identical thermal lifetime ratings. The substitute's higher voltage rating provides operational margin in circuits designed for the original 2.5 V specification. Packaging dimensions and surface mount compatibility are identical, eliminating PCB redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CT0J101R directly replace the Rubycon 2.5SLG100M without PCB modifications?

A: Yes. Both components use identical 2917 (7343 Metric) packaging with matching land pattern dimensions (0.287" L x 0.169" W / 7.30 mm x 4.30 mm). No PCB layout changes are required.

Q: What is the impact of the higher voltage rating (6.3 V vs. 2.5 V) on circuit operation?

A: The substitute's 6.3 V rating is backward compatible with 2.5 V circuit designs. Higher voltage rating does not degrade performance in lower voltage applications and provides additional operational margin.

Q: How does the ESR difference (15 mOhm vs. 9 mOhm) affect circuit performance?

A: The 6 mOhm ESR increase is within acceptable tolerance for general purpose applications. Ripple current handling capacity of the substitute (5.1 A @ 100 kHz) exceeds the original specification (2.7 A @ 100 kHz), maintaining thermal performance margins.

Q: Are there any compliance or certification differences between the two parts?

A: Both components maintain ROHS3 compliance, REACH Unaffected status, and identical EAR99 export classification. No compliance barriers exist for substitution.

Q: What is the significance of the Panasonic part being active status versus the Rubycon part being obsolete?

A: Active product status ensures continued manufacturing, availability through authorized distributors, and long-term supply chain reliability. This is the primary driver for substitution in obsolete component replacement scenarios.
