Rubycon 2.5SLG100M1.4X7.3 Equivalent & Substitute Parts

Part Overview

The Rubycon 2.5SLG100M1.4X7.3 is a 100 µF aluminum polymer capacitor rated at 2.5 V, housed in a 2917 (7343 Metric) surface mount package. This component belongs to the PC-CON and SLG series and is designated as not for new designs. Due to its discontinued status and limited availability for new applications, identifying equivalent substitute parts is necessary for design continuity and component sourcing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Rubycon 2.5SLG100M1.4X7.3 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value: 100 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Voltage rating: Substitute must equal or exceed 2.5 V
• Type: Aluminum - Polymer (same dielectric technology)
• Operating temperature range: Must cover -55°C ~ 105°C minimum
• Lifetime specification: 2000 Hrs @ 105°C or better

Mechanical Compatibility:

• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) footprint (exact match required)

Compliance Requirements:

• RoHS3 Compliant status
• MSL rating: 3 or better

The Panasonic EEF-CX0J101R meets all substitution criteria with identical capacitance, tolerance, package, and footprint, while offering superior voltage rating and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CX0J101R is a direct functional substitute for the Rubycon 2.5SLG100M1.4X7.3. Both components share identical electrical specifications for capacitance, tolerance, and thermal lifetime, with matching mechanical form factors and surface mount compatibility.

The Panasonic substitute provides advantages in product lifecycle status (Active vs. Not For New Designs) and offers higher voltage rating (6.3 V vs. 2.5 V), which provides additional design margin in applications where the original 2.5 V rating is sufficient. The substitute's higher ripple current capability (5.1 A vs. 2.7 A @ 100 kHz) and increased ESR (15 mOhm vs. 9 mOhm) remain within acceptable ranges for general purpose applications.

Both components maintain ROHS3 compliance and identical operating temperature specifications. The substitute is available in significantly higher inventory quantities, supporting production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CX0J101R be used as a direct replacement for the Rubycon 2.5SLG100M1.4X7.3?

A: Yes. Both components have identical capacitance (100 µF), tolerance (±20%), package (2917 / 7343 Metric), and physical footprint. The Panasonic substitute is electrically and mechanically compatible for direct PCB substitution.

Q: Why does the Panasonic substitute have a higher voltage rating (6.3 V vs. 2.5 V)?

A: Higher voltage rating does not prevent substitution. In applications designed for 2.5 V operation, a 6.3 V rated capacitor operates safely with additional voltage margin. This is a standard engineering practice and does not compromise circuit function.

Q: What is the impact of the higher ESR in the Panasonic substitute (15 mOhm vs. 9 mOhm)?

A: The ESR difference of 6 mOhm is within acceptable tolerance for general purpose applications. Both components are rated for identical thermal lifetime (2000 Hrs @ 105°C) and ripple current handling. Circuit-specific analysis is required only for applications with stringent ESR requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the Rubycon 2.5SLG100M1.4X7.3 and Panasonic EEF-CX0J101R are ROHS3 compliant.

Q: What is the difference in ripple current capability?

A: The Panasonic substitute supports 5.1 A ripple current at 100 kHz, compared to 2.7 A for the original part. This higher capability provides additional design margin and does not affect substitution compatibility.

Q: Can I use the Panasonic substitute in new designs?

A: Yes. The Panasonic EEF-CX0J101R has Active product status, making it suitable for new design implementations. The original Rubycon part is designated Not For New Designs.
